The Government Assault Against Ivermectin and other Safe SARS-2 Treatments
Richard Gale and Gary Null PhD
Progressive Radio Network, September 1, 2021
Had the FDA and Anthony Fauci’s National Institute for Allergies and Infectious Disease (NIAID) started approving existing clinically-proven and inexpensive drugs for treating malaria, parasites and other pathogens at the start of the pandemic, millions of people would have been saved from experiencing serious infections or dying from the SARS-CoV-2 virus. Why federal health officials never followed this strategy is a question the mainstream media refuses to ask.
Another question that the medical establishment, let alone our compliant media, is why have they failed to ask whether there are reliable studies in the peer-reviewed literature and testimonies from thousands of day-to-day clinical physicians worldwide who treat Covid-19 patients with these drugs, in particular hydroxychloroquine (HCQ) and Ivermectin. We may also point out the many different natural remedies, such as nigella sativa, curcumin, vitamin D, melatonin, etc, which have been shown to be effective against SARS-2 infections. In most nations, there has been enormous success in treating Covid patients at the early and moderate stages of infection. However, in the US, Anthony Fauci, Bill Gates, the FDA and our federal medical officials have categorically denied their use. In fact during the past couple weeks, there has been an aggressive and concerted effort to erect obstacles to prevent the employment of these more effective drugs. More recently a widespread campaign is underway to denigrate them altogether.
For example, the TOGETHER trial is now touted by the mainstream media as a flagship study showing that ivermectin is ineffective and even dangerous to prescribe. The study was conducted by professor Edward Mills at McMaster University in Ontario. If we are to believe the New York Times, the trial, which enrolled 1,300 patients, was discontinued because Mills claimed the drug was no better than a placebo. However, there is strong reason to believe this entire trial was nothing less than a staged theatrical performance. When asked, Mills denied having any conflict of interests. However, Mills happens to be employed as a clinical trial advisor for the Bill and Melinda Gates Foundation. The Gates Foundation was also the trial’s principal funder. It may be noted that various organizations and agencies in other nations, such as the Health Products Regulatory Authority in South Africa, which have banned ivermectin, are often funded by Gates. It is naïve to believe that Gates has any philanthropic intentions whatsoever to see a highly effective treatment for SARS-2 infections reach worldwide approval. These drugs are in direct competition to his enormous investments and unwavering commitment to the Covid-19 vaccines.
In the meantime, Americans only have monoclonal antibody therapy and the controversial and ineffective drug Remdesivir at their disposal. Remdesivir’s average effectiveness for late stage treatment is only 22 percent. A Chinese study published in The Lancet found no statistically significant benefit in the drug and 12 percent of participants taking the drug had to discontinue treatment due to serious adverse effects, especially liver and kidney damage.
When questions are posited as a general argument for advocating expedient measures to protect public health during this pandemic, would it not have been wise to have prioritized for emergency use HCQ, Ivermectin, and other remedies with a record of curtailing Covid, such as the antibiotic azithromycin, zinc, selenium, Vitamins C and D, and melatonin as a first line of defense? There was absolutely no need to have waited for experimental vaccines or experimental drugs such as Remdesivir before the pandemic became uncontrollable. But this is what Fauci and Trump, and now Biden, permitted to happen.
If this strategy of medical intervention had been followed, would it have been successful? The answer is likely an unequivocal “yes”. Both HCQ and, even better, Ivermectin have been prophylactically prescribed by physicians working on pandemic’s front lines with enormous success. Yet those American physicians struggling to get this urgent message out to federal health officials are being marginalized and ridiculed en masse. Only in the US, the UK, France, South Africa and several other developed nations has there been a stubborn hubris to deny their effectiveness. The World Health Organization recommends Ivermectin for Covid-19 so why not the US and these other nations? Under oath, multiple physicians and professors at American medical schools have testified before Congress to present the scientific evidence supporting HCQ and Ivermectin. These are otherwise medical professionals at the very heart of treating Covid-19 patients.
Today, American journalism is in shambles. In fact, it is a disgrace. The American public is losing trust in the media. Whether it is CNN, the New York Times, the Washington Post, the liberal tabloid Daily Beast, NPR or PBS, each has unlimited resources to properly investigate the federal and institutional machinery behind the government health policies being thrust upon us. Yet no mainstream journalist has found the moral compass to bring this truth to the public.
In the meantime, we are allowing millions to die, and countless others to be seriously affected from a severe infection because of professional medical neglect and a healthcare system favoring the pharmaceutical industry’s frantic rush to develop expensive novel drugs and experimental vaccines. The incentive by the drug makers is to take every advantage available within the FDA’s emergency use loopholes to get their products approved as quickly as possible. The primary advantage is that these novel drugs and vaccines can then leap over regulatory hurdles, which otherwise would require them to conduct lengthy and thorough clinical trials to prove their efficacy and safety. The consequence is that none of the new pharmaceutical Covid-19 interventions have been adequately reviewed.
On the other hand, HCQ and Ivermectin have an established legacy of prior research and have been on the market for decades. Worldwide, it is not unreasonable to claim that billions of people have been treated with these drugs.
Below is a breakdown of the studies conducted so far for HCQ, Ivermectin and Vitamin D specifically for combatting the SARS-CoV-2 virus
Hydroxychloroquine
344 studies, 250 peer-reviewed have been conducted specifically for Covid-19
281 have been clinical trials that involved 4,583 scientists and over 407,627 patients
64% improvement in 31 early treatment trials
75% improvement in 13 early stage infection treatment mortality results
21% improvement in 190 late stage infection treatment trials (patients in serious condition)
23% improvement in 44 randomized controlled trials
Full list of HCQ studies and details: https://c19hcq.com
Ivermectin
131 studies, 52 peer-reviewed have been conducted specifically for Covid-19
63 have been clinical trials that involved 613 scientists and over 26,398 patients
58% improvement in 31 randomized controlled trials
86% improvement in 14 prophylaxis trials
72% improvement in 27 early stage infection treatment trials
40% improvement in 22 late stage infection treatment trials
58% improvement in 25 mortality results
Full list of Ivermectin studies and details: https://c19ivermectin.com
Other inexpensive repurposed drugs for treating SARS-2
Fluvoxamine
88% improvement in early treatment
29% improvement in late stage treatment
63% improvement in all 7 peer-reviewed studies
Vitamin D
101 studies conducted by over 875 scientists
63 sufficiency studies with 34,863 patients
33 treatment trials with 46,860 patients
42% improvement in 33 treatment trials
56% improvement in 68 sufficiency studies
55% improvement in 19 treatment mortality results
Full list of Vitamin D studies and details: https://c19vitamind.com
In contrast there have been 21 studies enrolling 35,744 patients in Remdesivir trials showing only a 22% improvement in all studies combined. This rate is below that of simply taking probiotics (5 studies at 24% improvement), melatonin (7 studies at 62% improvement), curcumin (4 studies at 71% improvement), nigella sativa (3 studies at 84% improvement), quercetin (4 studies at 76% improvement), and aspirin (7 studies at 37% improvement). Despite the small number of trials and low numbers of enrolled participants, early results indicate that greater attention and funding needs to be allocated for more rigorous research if there is to be any success in curbing SARS-2 infections’ severity.
Please share this information. The inept policies and measures being taken by our federal health officials and by both the former Trump and present Biden administrations are unparalleled in American healthcare history. And never before has the media been so willing to self-censor and been so grossly irresponsible to hide the published science and the truth.

Can low temperature-aged garlic enhance exercise performance?
Korea Univesity & National Institute of Agricultural Sciences (South Korea), October 8, 2021
Scientists from South Korea’s National Institute of Agricultural Sciences and Korea University looked at aged garlic to see whether it could help reduce fatigue. To do this, they conducted a study on mice fed with a special low-temperature-aged garlic (LTAG).
Their findings were published in the Journal of Medicinal Food.
Testing the fatigue-fighting effects of low temperature-aged garlic
The researchers chose to use LTAG because it lacked the pungent odor and spicy flavor of regular garlic, making it easier to use for animal testing.
To create the LTAG, the researchers stored garlic in a sealed container, aging at 60 C for 60 days. The resulting LTAG was then peeled and pulverized, before being added to 200 milliliters of 70 percent ethanol (EtOH), which was then subjected to ultrasonic extraction three times. This 70 percent EtOH and LTAG extract was then concentrated under a vacuum at 45 C and then lyophilized to create a dry LTAG residue.
After the creation of the LTAG, the researchers then separated mice into six groups. The first group was given a low dose of LTAG extract; the second was fed a high dose of LTAG extract; the third was given a low dose of garlic extract; and the fourth was given a high dose of garlic extract. The fifth and sixth groups consisted of normal mice that were given phosphate-buffered saline (PBS) instead of garlic. One of these control groups was made to exercise while the other group was not.
The mice in the five groups were forced to run on a treadmill for four weeks. With each passing week, the amount of exercise the mice would have to do on the treadmills would increase. This was done by increasing both the speed that the mice had to run, and the amount of time they had to spend running. (Related: How to alleviate fatigue with herbal medicine.)
After 28 days of treatment, five mice from each group were subjected to a final, exhaustive treadmill test. This test increased the treadmill speed from 15 meters per minute (m/min) to 40 m/min every 3 minutes. During this test, the running time was monitored until each mouse failed to follow the increase in speed on three consecutive occasions and lag occurred. At this point, the mouse’s total running time was recorded.
The effect of the LTAG on the levels of glucose, lactate dehydrogenase (LDH), free fatty acid (FFA) and lactate in the mice’s blood. Following the final exercise, the mice were killed and blood samples were collected from them. In addition, the mice’s gastrocnemius muscles were also isolated and frozen in liquid nitrogen for testing.
LTAG treated mice demonstrated less fatigue
Following the exhaustive running tests, the researchers found that the mice treated with LTAG extract were able to run for much longer than the control mice.
Meanwhile, looking at the blood tests, they noted that the mice treated with LTAG extract exhibited lower levels of glucose, LDH, FFA and lactate. More importantly, the LTAG treated mice had increased amounts of glycogen and creatine kinase (CK) in their muscles.
Glycogen storage is an important source of energy during exercise. It serves a central role in maintaining the body’s glucose homeostasis by supplementing blood glucose. Because of this, glycogen is seen as an accurate marker for fatigue, with increased glycogel levels closely associated with improved endurance and anti-fatigue effects.
CK, on the other hand, is known to be an accurate indicator of muscle damage. During muscle degeneration, muscle cells are dissolved and their contents enter the bloodstream. As a result, when muscle damage occurs, muscle CK comes out into the blood. As such, fatigue tends to lead to lower muscle CK levels and higher blood CK levels.
Higher levels of glycogen and muscle CK in the LTAG treated mice indicated that they experienced less fatigue than the other groups.
Based on these findings, the researchers believe that LTAG has potential for use as an anti-fatigue agent.
Mindfulness meditation helps preterm-born adolescents
University of Geneva (Switzerland), October 7, 2021
Adolescents born prematurely present a high risk of developing executive, behavioral and socio-emotional difficulties. Now, researchers from Geneva University Hospitals (HUG) and the University of Geneva (UNIGE) have revealed that practicing mindfulness may help improve these various skills. The study, published in the journal Scientific Reports, suggests using mindfulness as a means of clinical intervention with adolescents, whether prematurely born or not.
Several studies have already shown that very preterm (VPT) children and adolescents are at higher risk of exhibiting cognitive and socio-emotional problems that may persist into adulthood. To help them overcome the difficulties they face, researchers from the HUG and UNIGE have set up an intervention based on mindfulness, a technique known to have beneficial effects in these areas. Mindfulness consists in training the mind to focus on the present moment, concentrating on physical sensations, on breathing, on the weight of one's body, and even on one's feelings and thoughts, completely judgment-free. The mindfulness-based interventions generally take place in a group with an instructor along with invitations to practice individually at home.
To accurately assess the effects of mindfulness, a randomized controlled trial was performed with young adolescents aged 10 to 14, born before 32 weeks gestational weeks. Scientists quickly found that mindfulness improves the regulation of cognitive, social and emotional functions, in other worlds, our brain's ability to interact with our environment. Indeed, it increases the ability to focus on the present—on thoughts, emotions and physical sensations, with curiosity and non-judgment. Thanks to this practice, adolescents improve their executive functions, i.e. the mental processes that enable us to control our behavior to successfully achieve a goal. As a result, young people find it easier to focus, manage and regulate their behavior and emotions in everyday life.
For eight weeks, the young teens spent an hour and a half each week with two mindfulness instructors. They were further encouraged to practice mindfulness daily at home.
Parents were also involved in this study. They were asked to observe their child's executive functions, for example the ability to regulate their emotions and attentional control, their relationships with others and their behavior. The adolescents also underwent a series of computerized tasks to assess their reactions to events. A comparison of their test results with a control group that did not practice mindfulness shows a positive impact of the intervention on the adolescents' everyday life and on their ability to react to new events.
"Each teenager is unique, with their own strenghts and difficulties. Through their involvement in this study, our volunteers have contributed to show that mindfulness can help many young people to feel better, to refocus and to face the world, whether they were born preterm born or not," agree Dr. Russia Hà-Vinh Leuchter, a consultant in the Division of Development and Growth, Department of Paediatrics, Gynaecology and Obstetrics at Geneva University Hospitals, and Dr. Vanessa Siffredi, a researcher at the Child Development Laboratory at the Department of Paediatrics, Gynaecology and Obstetrics at the UNIGE Faculty of Medicine, two of the authors of this work. "However, while the practice of meditation can be a useful resource, it is important to be accompanied by well-trained instructors", they specify.
The adolescents who took part in the program are now between 14 and 18 years. Scientists are currently evaluating the long-term effects of mindfulness-based intervention on their daily attention and stress. Furthermore, to validate their clinical data with neurobiological measurements, researchers are currently studying the effects of mindfulness on the brain using magnetic resonance imaging (MRI).
Iron deficiency in middle age is linked with higher risk of developing heart disease
University Heart and Vasculature Centre Hamburg (Germany) 6 October 2021
Approximately 10% of new coronary heart disease cases occurring within a decade of middle age could be avoided by preventing iron deficiency, suggests a study published today in ESC Heart Failure, a journal of the European Society of Cardiology (ESC).1
“This was an observational study and we cannot conclude that iron deficiency causes heart disease,” said study author Dr. Benedikt Schrage of the University Heart and Vasculature Centre Hamburg, Germany. “However, evidence is growing that there is a link and these findings provide the basis for further research to confirm the results.”
Previous studies have shown that in patients with cardiovascular diseases such as heart failure, iron deficiency was linked to worse outcomes including hospitalisations and death. Treatment with intravenous iron improved symptoms, functional capacity, and quality of life in patients with heart failure and iron deficiency enrolled in the FAIR-HF trial.2 Based on these results, the FAIR-HF 2 trial is investigating the impact of intravenous iron supplementation on the risk of death in patients with heart failure.
The current study aimed to examine whether the association between iron deficiency and outcomes was also observed in the general population.
The study included 12,164 individuals from three European population-based cohorts. The median age was 59 years and 55% were women. During the baseline study visit, cardiovascular risk factors and comorbidities such as smoking, obesity, diabetes and cholesterol were assessed via a thorough clinical assessment including blood samples.
Participants were classified as iron deficient or not according to two definitions: 1) absolute iron deficiency, which only includes stored iron (ferritin); and 2) functional iron deficiency, which includes iron in storage (ferritin) and iron in circulation for use by the body (transferrin).
Dr. Schrage explained: “Absolute iron deficiency is the traditional way of assessing iron status but it misses circulating iron. The functional definition is more accurate as it includes both measures and picks up those with sufficient stores but not enough in circulation for the body to work properly.”
Participants were followed up for incident coronary heart disease and stroke, death due to cardiovascular disease, and all-cause death. The researchers analysed the association between iron deficiency and incident coronary heart disease, stroke, cardiovascular mortality, and all-cause mortality after adjustments for age, sex, smoking, cholesterol, blood pressure, diabetes, body mass index, and inflammation. Participants with a history of coronary heart disease or stroke at baseline were excluded from the incident disease analyses.
At baseline, 60% of participants had absolute iron deficiency and 64% had functional iron deficiency. During a median follow-up of 13.3 years there were 2,212 (18.2%) deaths. Of these, a total of 573 individuals (4.7%) died from a cardiovascular cause. Incidence coronary heart disease and stroke were diagnosed in 1,033 (8.5%) and 766 (6.3%) participants, respectively.
Functional iron deficiency was associated with a 24% higher risk of coronary heart disease, 26% raised risk of cardiovascular mortality, and 12% increased risk of all-cause mortality compared with no functional iron deficiency. Absolute iron deficiency was associated with a 20% raised risk of coronary heart disease compared with no absolute iron deficiency, but was not linked with mortality. There were no associations between iron status and incident stroke.
The researchers calculated the population attributable fraction, which estimates the proportion of events in 10 years that would have been avoided if all individuals had the risk of those without iron deficiency at baseline. The models were adjusted for age, sex, smoking, cholesterol, blood pressure, diabetes, body mass index, and inflammation. Within a 10-year period, 5.4% of all deaths, 11.7% of cardiovascular deaths, and 10.7% of new coronary heart disease diagnoses were attributable to functional iron deficiency.
“This analysis suggests that if iron deficiency had been absent at baseline, about 5% of deaths, 12% of cardiovascular deaths, and 11% of new coronary heart disease diagnoses would not have occurred in the following decade,” said Dr. Schrage.
“The study showed that iron deficiency was highly prevalent in this middle-aged population, with nearly two-thirds having functional iron deficiency,” said Dr. Schrage. “These individuals were more likely to develop heart disease and were also more likely to die during the next 13 years.”
Dr. Schrage noted that future studies should examine these associations in younger and non-European cohorts. He said: “If the relationships are confirmed, the next step would be a randomised trial investigating the effect of treating iron deficiency in the general population.”
Consumption of a bioactive compound from Neem plant could significantly suppress development of prostate cancer
National University of Singapore, September 29, 2021
Oral administration of nimbolide, over 12 weeks shows reduction of prostate tumor size by up to 70 per cent and decrease in tumor metastasis by up to 50 per cent
A team of international researchers led by Associate Professor Gautam Sethi from the Department of Pharmacology at the Yong Loo Lin School of Medicine at the National University of Singapore (NUS) has found that nimbolide, a bioactive terpenoid compound derived from Azadirachta indica or more commonly known as the neem plant, could reduce the size of prostate tumor by up to 70 per cent and suppress its spread or metastasis by half.
Prostate cancer is one of the most commonly diagnosed cancers worldwide. However, currently available therapies for metastatic prostate cancer are only marginally effective. Hence, there is a need for more novel treatment alternatives and options.
"Although the diverse anti-cancer effects of nimbolide have been reported in different cancer types, its potential effects on prostate cancer initiation and progression have not been demonstrated in scientific studies. In this research, we have demonstrated that nimbolide can inhibit tumor cell viability -- a cellular process that directly affects the ability of a cell to proliferate, grow, divide, or repair damaged cell components -- and induce programmed cell death in prostate cancer cells," said Assoc Prof Sethi.
Nimbolide: promising effects on prostate cancer
Cell invasion and migration are key steps during tumor metastasis. The NUS-led study revealed that nimbolide can significantly suppress cell invasion and migration of prostate cancer cells, suggesting its ability to reduce tumor metastasis.
The researchers observed that upon the 12 weeks of administering nimbolide, the size of prostate cancer tumor was reduced by as much as 70 per cent and its metastasis decreased by about 50 per cent, without exhibiting any significant adverse effects.
"This is possible because a direct target of nimbolide in prostate cancer is glutathione reductase, an enzyme which is responsible for maintaining the antioxidant system that regulates the STAT3 gene in the body. The activation of the STAT3 gene has been reported to contribute to prostate tumor growth and metastasis," explained Assoc Prof Sethi. "We have found that nimbolide can substantially inhibit STAT3 activation and thereby abrogating the growth and metastasis of prostate tumor," he added.
The findings of the study were published in the April 2016 issue of the scientific journal Antioxidants & Redox Signaling. This work was carried out in collaboration with Professor Goh Boon Cher of Cancer Science Institute of Singapore at NUS, Professor Hui Kam Man of National Cancer Centre Singapore and Professor Ahn Kwang Seok of Kyung Hee University.
The neem plant belongs to the mahogany tree family that is originally native to India and the Indian sub-continent. It has been part of traditional Asian medicine for centuries and is typically used in Indian Ayurvedic medicine. Today, neem leaves and bark have been incorporated into many personal care products such as soaps, toothpaste, skincare and even dietary supplements.
Review looks at the efficacy of acupuncture in treating insulin resistance
Guangzhou University of Chinese Medicine (China), October 8, 2021
In their report, researcherss from Guangzhou University of Chinese Medicine in China explored the role of acupuncture in treating insulin resistance. The study was published in the journal Complementary Therapies in Clinical Practice.
Earlier studies have reported the effectiveness of acupuncture in treating insulin resistance and related conditions.
The review looked at acupuncture and its effects on clinical outcomes.
The researchers searched the following databases for randomized controlled trials involving insulin resistance patients treated with acupuncture:
Cochrane Central Register of Controlled Trials
Embase
Medline (via OVID)
China National Knowledge Infrastructure (CNKI)
Wan Fang and China Science and Technology Journal Database (VIP)
The studies show that homeostasis model assessment of insulin resistance significantly decreased with acupuncture treatment.
Other significant decreases include fasting blood glucose, postprandial blood glucose and fasting insulin.
Acupuncture increased insulin sensitivity with very few adverse effects.
In sum, acupuncture is a safe and effective alternative treatment for insulin resistance.
Blueberries may improve attention in children following double-blind trial
University of Reading (UK), October 10, 2021
Primary school children could show better attention by consuming flavonoid-rich blueberries, following a study conducted by the University of Reading.
In a paper published in Food & Function, a group of 7-10 year olds who consumed a drink containing wild blueberries or a matched placebo and were tested on their speed and accuracy in completing an executive task function on a computer.
The double blind trial found that the children who consumed the flavonoid-rich blueberry drink had 9% quicker reaction times on the test without any sacrifice of accuracy. In particular, the effect was more noticeable as the tests got harder.
Professor Claire Williams, a neuroscience professor at the University of Reading said:
"This is the first time that we have seen the positive impact that flavonoids can have on the executive function of children. We designed this double blind trial especially to test how flavonoids would impact on attention in young people as it's an area of cognitive performance that hasn't been measured before.
"We used wild blueberries as they are rich in flavonoids, which are compounds found naturally in foods such as fruits and their juices, vegetables and tea. They have been associated with a range of health benefits including antioxidant and anti-inflammatory effects, and our latest findings continue to show that there is a beneficial cognitive effect of consuming fruit and vegetables, tea, coffee and even dark chocolate which all contain flavonoids."
The children were then asked to pay attention to an array of arrows shown on a PC screen and press a key corresponding to the direction that the central arrow was facing. The task was repeated over a number of trials, where cognitive demand was manipulated by varying how quickly the arrows appeared, whether there were additional arrows appearing either side of the central arrow, and whether the flanking arrows were pointing in the same/different direction as the central arrow.
Previous Reading research has shown that consuming wild blueberries can improve mood in children and young people, simple memory recall in primary school children, and that other flavonoid rich drinks such as orange juice, can also improve memory and concentration.
The Wild Blueberry Association of North America provided a freeze-dried powder made from wild blueberries which was used in the study but did not provide any additional financial support and did not play a role in the design of the study.
Wild blueberries are grown and harvested in North America, and are smaller than regular blueberries, and are higher in flavonoids compared to regular varieties.
The double-blind trial used a flavonoid-rich wild blueberry drink, with a matched placebo contained 8.9g of fructose, 7.99g of glucose and 4 mg of vitamin C matching the levels of nutrients found in the blueberry drink.
The amount of fructose is akin to levels found in a standard pear.
This was an executive function task- requiring participants to pay attention to stimuli appearing on screen and responding correctly. The task was a simple one- responding to the direction of an arrow in the middle of a screen (by pressing left/right arrow key) but we then varied how quickly the stimuli appeared, whether there was additional arrows appearing either side of the stimuli and whether those flanking arrows were pointing in the same/different direction as they direction you had to respond.
There are 6 main classes of flavonoids:
Anthocyanins – found in berry fruits such as the blueberries used in this study and also in red wine.
Flavonols - found in onions, leeks, and broccoli
Flavones - found in parsley and celery,
Isoflavones - found in soy and soy products,
Flavanones - found in citrus fruit and tomatoes
Flavanols—found in green tea, red wine, and chocolate
Nocebo effect: Does a drug's high price tag cause its own side effects?
University Medical Center Hamburg (Germany), October 5, 2021
Pricey drugs may make people more vulnerable to perceiving side effects, a new study suggests—and the phenomenon is not just "in their heads."
The study delved into the so-called "nocebo effect." It's the negative version of the well-known placebo effect, where people feel better after receiving a therapy because they expected good things.
With the nocebo effect, patients' worries over treatment side effects make them feel sick.
In this study, researchers found that people were more likely to report painful side effects from a fake drug when told it was expensive.
But it wasn't just something people were "making up." Using brain imaging, the researchers traced the phenomenon to specific activity patterns in the brain and spine.
"These findings are a strong argument against the perception of placebo and nocebo effects as being only 'fake' effects—created purely by imagination or delusions of the patient," said lead researcher Alexandra Tinnermann. She is with the University Medical Center Hamburg-Eppendorf, in Germany.
Dr. Luana Colloca, a researcher at the University of Maryland in Baltimore, agreed.
"This is not merely a reflection of people's biases," said Colloca, who wrote an editorial published with the study.
"Expectations do modulate symptoms and patients' responses to treatment," she said.
For the study, Tinnermann's team recruited 49 healthy volunteers and randomly assigned them to test one of two itch-relieving "medical creams."
In reality, both creams were identical and contained no active ingredients. However, people in both groups were told that the products could have the side effect of making the skin more sensitive to pain.
There was only one apparent difference between the two phony creams: One came in fancy packing with a high price tag; the other was cheap.
After participants applied the creams to their forearms, the researchers had them undergo a standard test that measured their tolerance for heat-induced pain.
It turned out that people who'd used the expensive cream were more sensitive to pain during the tests. On average, their pain rating hovered around a 15—within the "mild" pain range—whereas people using the cheap cream barely registered any discomfort.
It's likely, Tinnermann said, that people expect a pricey medication to be potent—which could also make them expect more side effects.
Colloca agreed. We are all "vulnerable" to such outside influences, she said, be it a drug's price or how it's given (by IV versus mouth, for instance).
However, we are not just imagining those placebo or nocebo effects, both researchers noted.
Using functional MRI brain scans, Tinnermann's team found specific patterns of nervous system activity in people who had a nocebo response to the pricey cream.
That included a change in "communication" between certain brain structures and the spinal cord, Tinnermann said.
According to Colloca, research like this can have practical uses. Doctors could, for instance, inform patients that drug prices or other factors can sway their expectations about a treatment's benefits and risks—and that, in turn, can influence whether they feel better or develop side effects.
There is, however, no research into whether that kind of knowledge helps prevent patients from the nocebo effect, Tinnermann said.
But, she added, health professionals can be aware that patients' expectations "play a huge role in medicine"—and be mindful of how they talk about a medication and its possible side effects.
It's an important matter, Colloca said, because the nocebo effect can cause people to stop taking needed medications.
Colloca pointed to the example of cholesterol-lowering statins.
The potential for those medications to cause muscle pain has been widely reported. And one recent study found evidence that this knowledge can make statin users more likely to report muscle pain side effects.
Other research, Colloca said, has shown that when people stop taking their statins, their risk of heart attack and stroke rises.

Raspberries, ellagic acid reveal benefits in two studies
Oregon State University, October 1, 2021.
Articles that appeared recently in the Journal of Berry Research report that raspberries and compounds present in the fruit could help support healthy body mass and motor function, including balance, coordination and strength.
In one study, Neil Shay and colleagues at Oregon State University fed mice a high fat, high sugar diet plus one of the following: raspberry juice concentrate, raspberry puree concentrate, raspberry fruit powder, raspberry seed extract, ellagic acid (a polyphenol that occurs in a relatively high amount in raspberries), raspberry ketone, or a combination of raspberry ketone and ellagic acid. Additional groups of animals received a high fat, high sugar diet alone or a low fat diet.
While mice that received the high fat and sugar diet alone experienced a significant increase in body mass, the addition of raspberry juice concentrate, raspberry puree concentrate or ellagic acid plus raspberry ketone helped prevent this effect. Of note, mice that received raspberry juice concentrate experienced gains similar to those of animals given a low fat diet. "We hope that the findings from this study can help guide the design of future clinical trials," Dr Shay stated.
In another study, Barbara Shukitt-Hale, PhD, and her associates at Tufts University's Human Nutrition Research Center on Aging gave 19 month old rats a control diet or a diet enhanced with raspberry extract for 11 weeks. Psychomotor behavior was assessed during week 7 and cognitive testing was conducted during weeks 9-10.
Animals that received raspberry performed better on psychomotor coordination and balance, and had better muscle tone, strength and stamina than those that received a control diet. "These results may have important implications for healthy aging," stated Dr Shukitt-Hale. "While further research in humans is necessary, animal model studies are helpful in identifying deficits associated with normal aging."
Massage doesn't just make muscles feel better, it makes them heal faster and stronger
Harvard University, October 6, 2021
Massage has been used to treat sore, injured muscles for more than 3,000 years, and today many athletes swear by massage guns to rehabilitate their bodies. But other than making people feel good, do these "mechanotherapies" actually improve healing after severe injury? According to a new study from researchers at Harvard's Wyss Institute for Biologically Inspired Engineering and John A. Paulson School of Engineering and Applied Sciences (SEAS), the answer is "yes."
Using a custom-designed robotic system to deliver consistent and tunable compressive forces to mice's leg muscles, the team found that this mechanical loading (ML) rapidly clears immune cells called neutrophils out of severely injured muscle tissue. This process also removed inflammatory cytokinesreleased by neutrophils from the muscles, enhancing the process of muscle fiber regeneration. The research is published in Science Translational Medicine.
"Lots of people have been trying to study the beneficial effects of massage and other mechanotherapies on the body, but up to this point it hadn't been done in a systematic, reproducible way. Our work shows a very clear connection between mechanical stimulation and immune function. This has promise for regenerating a wide variety of tissues including bone, tendon, hair, and skin, and can also be used in patients with diseases that prevent the use of drug-based interventions," said first author Bo Ri Seo, Ph.D., who is a Postdoctoral Fellow in the lab of Core Faculty member Dave Mooney, Ph.D. at the Wyss Institute and SEAS.
Seo and her coauthors started exploring the effects of mechanotherapy on injured tissues in mice several years ago, and found that it doubled the rate of muscle regeneration and reduced tissue scarring over the course of two weeks. Excited by the idea that mechanical stimulation alone can foster regeneration and enhance muscle function, the team decided to probe more deeply into exactly how that process worked in the body, and to figure out what parameters would maximize healing.
They teamed up with soft robotics experts in the Harvard Biodesign Lab, led by Wyss Associate Faculty member Conor Walsh, Ph.D., to create a small device that used sensors and actuators to monitor and control the force applied to the limb of a mouse. " The device we created allows us to precisely control parameters like the amount and frequency of force applied, enabling a much more systematic approach to understanding tissue healing than would be possible with a manual approach," said co-second author Christopher Payne, Ph.D., a former Postdoctoral Fellow at the Wyss Institute and the Harvard Biodesign Lab who is now a Robotics Engineer at Viam, Inc.
Once the device was ready, the team experimented with applying force to mice's leg muscles via a soft silicone tip and used ultrasound to get a look at what happened to the tissue in response. They observed that the muscles experienced a strain of between 10-40%, confirming that the tissues were experiencing mechanical force. They also used those ultrasound imaging data to develop and validate a computational model that could predict the amount of tissue strain under different loading forces.
They then applied consistent, repeated force to injured muscles for 14 days. While both treated and untreated muscles displayed a reduction in the amount of damaged muscle fibers, the reduction was more pronounced and the cross-sectional area of the fibers was larger in the treated muscle, indicating that treatment had led to greater repair and strength recovery. The greater the force applied during treatment, the stronger the injured muscles became, confirming that mechanotherapy improves muscle recovery after injury. But how?
Evicting neutrophils to enhance regeneration
To answer that question, the scientists performed a detailed biological assessment, analyzing a wide range of inflammation-related factors called cytokines and chemokines in untreated vs. treated muscles. A subset of cytokines was dramatically lower in treated muscles after three days of mechanotherapy, and these cytokines are associated with the movement of immune cells called neutrophils, which play many roles in the inflammation process. Treated muscles also had fewer neutrophils in their tissue than untreated muscles, suggesting that the reduction in cytokines that attract them had caused the decrease in neutrophil infiltration.
The team had a hunch that the force applied to the muscle by the mechanotherapy effectively squeezed the neutrophils and cytokines out of the injured tissue. They confirmed this theory by injecting fluorescent molecules into the muscles and observing that the movement of the molecules was more significant with force application, supporting the idea that it helped to flush out the muscle tissue.
To pick apart what effect the neutrophils and their associated cytokines have on regenerating muscle fibers, the scientists performed in vitro studies in which they grew muscle progenitor cells (MPCs) in a medium in which neutrophils had previously been grown. They found that the number of MPCs increased, but the rate at which they differentiated (developed into other cell types) decreased, suggesting that neutrophil-secreted factors stimulate the growth of muscle cells, but the prolonged presence of those factors impairs the production of new muscle fibers.
"Neutrophils are known to kill and clear out pathogens and damaged tissue, but in this study we identified their direct impacts on muscle progenitor cell behaviors," said co-second author Stephanie McNamara, a former Post-Graduate Fellow at the Wyss Institute who is now an M.D.-Ph.D. student at Harvard Medical School (HMS). "While the inflammatory response is important for regeneration in the initial stages of healing, it is equally important that inflammation is quickly resolved to enable the regenerative processes to run its full course."
Seo and her colleagues then turned back to their in vivo model and analyzed the types of muscle fibers in the treated vs. untreated mice 14 days after injury. They found that type IIX fibers were prevalent in healthy muscle and treated muscle, but untreated injured muscle contained smaller numbers of type IIX fibers and increased numbers of type IIA fibers. This difference explained the enlarged fiber size and greater force production of treated muscles, as IIX fibers produce more force than IIA fibers.
Finally, the team homed in on the optimal amount of time for neutrophil presence in injured muscle by depleting neutrophils in the mice on the third day after injury. The treated mice's muscles showed larger fiber size and greater strength recovery than those in untreated mice, confirming that while neutrophils are necessary in the earliest stages of injury recovery, getting them out of the injury site early leads to improved muscle regeneration.
"These findings are remarkable because they indicate that we can influence the function of the body's immune system in a drug-free, non-invasive way," said Walsh, who is also the Paul A. Maeder Professor of Engineering and Applied Science at SEAS and whose group is experienced in developing wearable technology for diagnosing and treating disease. "This provides great motivation for the development of external, mechanical interventions to help accelerate and improve muscle and tissue healing that have the potential to be rapidly translated to the clinic."
The team is continuing to investigate this line of research with multiple projects in the lab. They plan to validate this mechanotherpeutic approach in larger animals, with the goal of being able to test its efficacy on humans. They also hope to test it on different types of injuries, age-related muscle loss, and muscle performance enhancement.
"The fields of mechanotherapy and immunotherapy rarely interact with each other, but this work is a testament to how crucial it is to consider both physical and biological elements when studying and working to improve human health," said Mooney, who is the corresponding author of the paper and the Robert P. Pinkas Family Professor of Bioengineering at SEAS.
"The idea that mechanics influence cell and tissue function was ridiculed until the last few decades, and while scientists have made great strides in establishing acceptance of this fact, we still know very little about how that process actually works at the organ level. This research has revealed a previously unknown type of interplay between mechanobiology and immunology that is critical for muscle tissue healing, in addition to describing a new form of mechanotherapy that potentially could be as potent as chemical or gene therapies, but much simpler and less invasive," said Wyss Founding Director Don Ingber, M.D., Ph.D., who is also the Judah Folkman Professor of Vascular Biology at (HMS) and the Vascular Biology Program at Boston Children's Hospital, as well as Professor of Bioengineering at SEAS.
Vitamin E could help protect older men from pneumonia
University of Helsinki (Finland), October 7 2021.
An article that appeared in Clinical Interventions in Aging reported a protective role for vitamin E against pneumonia in older men.
For the current investigation, Dr Harri Hemilä of the University of Helsinki, Finland analyzed data from the Alpha-Tocopherol Beta-Carotene (ATBC) Cancer Prevention Study conducted in Finland. The trial included 29,133 men between the ages of 50 to 69 years who smoked at least five cigarettes daily upon enrollment. Participants received alpha tocopherol (vitamin E), beta carotene, both supplements, or a placebo for five to eight years.
The current study was limited to 7,469 ATBC participants who started smoking at age 21 or older. Among this group, supplementation with vitamin E was associated with a 35% lower risk of developing pneumonia in comparison with those who did not receive the vitamin. Light smokers who engaged in leisure time exercise had a 69% lower risk compared with unsupplemented members of this subgroup. The risk in this subgroup of developing pneumonia by age 74 was 12.9%.
Among the one-third of the current study's population who quit smoking for a median period of two years, there was a 72% lower risk of pneumonia in association with vitamin E supplementation. In this group, exercisers who received vitamin E experienced an 81% lower pneumonia risk.
Dr Hemilä observed that the benefit for vitamin E in this study was strongest for older subjects—a group at higher risk of pneumonia.
"The current analysis of individual-level data suggests that trials on vitamin E and pneumonia on nonsmoking elderly males are warranted," he concluded.
Toxic fatty acids to blame for brain cell death after injury
New York University, October 7, 2021
Cells that normally nourish healthy brain cells called neurons release toxic fatty acids after neurons are damaged, a new study in rodents shows. This phenomenon is likely the driving factor behind most, if not all, diseases that affect brain function, as well as the natural breakdown of brain cells seen in aging, researchers say.
Previous research has pointed to astrocytes—a star-shaped glial cell of the central nervous system—as the culprits behind cell death seen in Parkinson's disease and dementia, among other neurodegenerative diseases. While many experts believed that these cells released a neuron-killing molecule to "clear away" damaged brain cells, the identity of this toxin has until now remained a mystery.
Led by researchers at NYU Grossman School of Medicine, the new investigation provides what they say is the first evidence that tissue damage prompts astrocytes to produce two kinds of fats, long-chain saturated free fatty acids and phosphatidylcholines. These fats then trigger cell death in damaged neurons, the electrically active cells that send messages throughout nerve tissue.
Publishing Oct. 6 in the journal Nature, the study also showed that when researchers blocked fatty acid formation in mice, 75 percent of neurons survived compared with 10 percent when the fatty acids were allowed to form. The researchers' earlier work showed that brain cells continued to function when shielded from astrocyte attacks.
"Our findings show that the toxic fatty acids produced by astrocytes play a critical role in brain cell death and provide a promising new target for treating, and perhaps even preventing, many neurodegenerative diseases," says study co-senior author Shane Liddelow, Ph.D.
Liddelow, an assistant professor in the Department of Neuroscience and Physiology at NYU Langone Health, adds that targeting these fats instead of the cells that produce them may be a safer approach to treating neurodegenerative diseasesbecause astrocytes feed nerve cells and clear away their waste. Stopping them from working altogether could interfere with healthy brain function.
Although it remains unclear why astrocytes produce these toxins, it is possible they evolved to destroy damaged cells before they can harm their neighbors, says Liddelow. He notes that while healthy cells are not harmed by the toxins, neurons become susceptible to the damaging effects when they are injured, mutated, or infected by prions, the contagious, misfolded proteins that play a major role in mad cow disease and similar illnesses. Perhaps in chronic diseases like dementia, this otherwise helpful process goes off track and becomes a problem, the study authors say.
For the investigation, researchers analyzed the molecules released by astrocytes collected from rodents. They also genetically engineered some groups of mice to prevent the normal production of the toxic fats and looked to see whether neuron death occurred after an acute injury.
"Our results provide what is likely the most detailed molecular map to date of how tissue damage leads to brain cell death, enabling researchers to better understand why neurons die in all kinds of diseases," says Liddelow, also an assistant professor in the Department of Ophthalmology at NYU Langone.
Liddelow cautions that while the findings are promising, the genetic techniques used to block the enzyme that produces toxic fatty acids in mice are not ready for use in humans. As a result, the researchers next plan is to explore safe and effective ways to interfere with the release of the toxins in human patients. Liddelow and his colleagues had previously shown these neurotoxic astrocytes in the brains of patients with Parkinson's, Huntington's disease, and multiple sclerosis, among other diseases.
Clinical trial for nicotinamide riboside: Vitamin safely boosts levels of important cell metabolite linked to multiple health benefits
University of Iowa Health Care, October 3, 2021
In the first controlled clinical trial of nicotinamide riboside (NR), a newly discovered form of Vitamin B3, researchers have shown that the compound is safe for humans and increases levels of a cell metabolite that is critical for cellular energy production and protection against stress and DNA damage.
Studies in mice have shown that boosting the levels of this cell metabolite -- known as NAD+ -- can produce multiple health benefits, including resistance to weight gain, improved control of blood sugar and cholesterol, reduced nerve damage, and longer lifespan. Levels of NAD+ diminish with age, and it has been suggested that loss of this metabolite may play a role in age-related health decline.
These findings in animal studies have spurred people to take commercially available NR supplements designed to boost NAD+. However, these over-the-counter supplements have not undergone clinical trials to see if they work in people.
The new research, reported in the journal Nature Communications, was led by Charles Brenner, PhD, professor and Roy J. Carver Chair of Biochemistry at the University of Iowa Carver College of Medicine in collaboration with colleagues at Queens University Belfast and ChromaDex Corp. (NASDAQ: CDXC), which supplied the NR used in the trial. Brenner is a consultant for ChromaDex. He also is co-founder and Chief Scientific Adviser of ProHealthspan, which sells NR supplements under the trade name Tru NIAGEN®.
The human trial involved six men and six women, all healthy. Each participant received single oral doses of 100 mg, 300 mg, or 1,000 mg of NR in a different sequence with a seven-day gap between doses. After each dose, blood and urine samples were collected and analyzed by Brenner's lab to measure various NAD+ metabolites in a process called metabolomics. The trial showed that the NR vitamin increased NAD+ metabolism by amounts directly related to the dose, and there were no serious side effects with any of the doses.
"This trial shows that oral NR safely boosts human NAD+ metabolism," Brenner says. "We are excited because everything we are learning from animal systems indicates that the effectiveness of NR depends on preserving and/or boosting NAD+ and related compounds in the face of metabolic stresses. Because the levels of supplementation in mice that produce beneficial effects are achievable in people, it appears than health benefits of NR will be translatable to humans safely."
The next step will be to study the effect of longer duration NR supplementation on NAD+ metabolism in healthy adults, but Brenner also has plans to test the effects of NR in people with diseases and health conditions, including elevated cholesterol, obesity and diabetes, and people at risk for chemotherapeutic peripheral neuropathy.
Prior to the formal clinical trial, Brenner conducted a pilot human study -- on himself. In 2004, he had discovered that NR is a natural product found in milk and that there is pathway to convert NR to NAD+ in people. More than a decade of research on NR metabolic pathways and health effects in mice and rats had convinced him that NR supplementation had real promise to improve human health and wellness. After consulting with UI's institutional review board, he conducted an experiment in which he took 1 gram of NR once a day for seven days, and his team analyzed blood and urine samples using mass spectrometry. The experiment showed that Brenner's blood NAD+ increased by about 2.7 times. In addition, though he reported immediate sensitivity to flushing with the related compound niacin, he did not experience any side effects taking NR.
The biggest surprise from his metabolomic analysis was an increase in a metabolite called NAAD, which was multiplied by 45 times, from trace levels to amounts in the micromolar range that were easily detectable.
"While this was unexpected, I thought it might be useful," Brenner says. "NAD+ is an abundant metabolite and it is sometimes hard to see the needle move on levels of abundant metabolites. But when you can look at a low-abundance metabolite that goes from undetectable to easily detectable, there is a great signal to noise ratio, meaning that NAAD levels could be a useful biomarker for tracking increases in NAD+ in human trials."
Brenner notes this was a case of bidirectional translational science; having learned something from the initial human experiment, his team was able to return to laboratory mice to explore the unexpected NAAD finding in more detail.
Brenner's mouse study showed that NAAD is formed from NR and confirmed that NAAD levels are a strong biomarker for increased NAD+ metabolism. The experiments also revealed more detail about NAD+ metabolic pathways.
In particular, the researchers compared the ability of all three NAD+ precursor vitamins -- NR, niacin, and nicotinamide -- to boost NAD+ metabolism and stimulate the activity of certain enzymes, which have been linked to longevity and healthbenefits. The study showed for the first time that oral NR is superior to nicotinamide, which is better than niacin in terms of the total amount of NAD+ produced at an equivalent dose. NR was also the best of the three in stimulating the activity of sirtuin enzymes. However, in this case, NR was the best at stimulating sirtuin-like activities, followed by niacin, followed by nicotinamide.
The information from the mouse study subsequently helped Brenner's team design the formal clinical trial. In addition to showing that NR boosts NAD+ in humans without adverse effects, the trial confirmed that NAAD is a highly sensitive biomarker of NAD+ supplementation in people.
"Now that we have demonstrated safety in this small clinical trial, we are in a position to find out if the health benefits that we have seen in animals can be reproduced in people," says Brenner, who also is co-director of the Obesity Research and Education Initiative, professor of internal medicine, and a member of the Fraternal Order of Eagles Diabetes Research Center at the UI.
Protecting the ozone layer is delivering vast health benefits
Montreal Protocol will spare Americans from 443 million skin cancer cases
National Center for Atmospheric Research, October 7, 2021
An international agreement to protect the ozone layer is expected to prevent 443 million cases of skin cancer and 63 million cataract cases for people born in the United States through the end of this century, according to new research.
The research team, by scientists at the National Center for Atmospheric Research (NCAR), ICF Consulting, and U.S. Environmental Protection Agency (EPA), focused on the far-reaching impacts of a landmark 1987 treaty known as the Montreal Protocol and later amendments that substantially strengthened it. The agreement phased out the use of chemicals such as chlorofluorocarbons (CFCs) that destroy ozone in the stratosphere.
Stratospheric ozone shields the planet from harmful levels of the Sun’s ultraviolet (UV) radiation, protecting life on Earth.
To measure the long-term effects of the Montreal Protocol, the scientists developed a computer modeling approach that enabled them to look to both the past and the future by simulating the treaty’s impact on Americans born between 1890 and 2100. The modeling revealed the treaty’s effect on stratospheric ozone, the associated reductions in ultraviolet radiation, and the resulting health benefits.
In addition to the number of skin cancer and cataract cases that were avoided, the study also showed that the treaty, as most recently amended, will prevent approximately 2.3 million skin cancer deaths in the U.S.
“It’s very encouraging,” said NCAR scientist Julia Lee-Taylor, a co-author of the study. “It shows that, given the will, the nations of the world can come together to solve global environmental problems.”
The study, funded by the EPA, was published in ACS Earth and Space Chemistry. NCAR is sponsored by the National Science Foundation.
Mounting concerns over the ozone layer
Scientists in the 1970s began highlighting the threat to the ozone layer when they found that CFCs, used as refrigerants and in other applications, release chlorine atoms in the stratosphere that set off chemical reactions that destroy ozone. Concerns mounted the following decade with the discovery of an Antarctic ozone hole.
The loss of stratospheric ozone would be catastrophic, as high levels of UV radiation have been linked to certain types of skin cancer, cataracts, and immunological disorders. The ozone layer also protects terrestrial and aquatic ecosystems, as well as agriculture.
Policy makers responded to the threat with the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer, in which nations agreed to curtail the use of certain ozone-destroying substances. Subsequent amendments strengthened the treaty by expanding the list of ozone-destroying substances (such as halons and hydrochlorofluorocarbons, or HCFCs) and accelerating the timeline for phasing out their use. The amendments were based on Input from the scientific community, including a number of NCAR scientists, that were summarized in quadrennial Ozone Assessment reports.
To quantify the impacts of the treaty, the research team built a model known as the Atmospheric and Health Effects Framework. This model, which draws on various data sources about ozone, public health, and population demographics, consists of five computational steps. These simulate past and future emissions of ozone-destroying substances, the impacts of those substances on stratospheric ozone, the resulting changes in ground-level UV radiation, the U.S. population’s exposure to UV radiation, and the incidence and mortality of health effects resulting from the exposure.
The results showed UV radiation levels returning to 1980 levels by the mid-2040s under the amended treaty. In contrast, UV levels would have continued to increase throughout this century if the treaty had not been amended, and they would have soared far higher without any treaty at all.
Even with the amendments, the simulations show excess cases of cataracts and various types of skin cancer beginning to occur with the onset of ozone depletion and peaking decades later as the population exposed to the highest UV levels ages. Those born between 1900 and 2040 experience heightened cases of skin cancer and cataracts, with the worst health outcomes affecting those born between about 1950 and 2000.
However, the health impacts would have been far more severe without the treaty, with cases of skin cancer and cataracts rising at an increasingly rapid rate through the century.
“We peeled away from disaster,” Lee-Taylor said. “What is eye popping is what would have happened by the end of this century if not for the Montreal Protocol. By 2080, the amount of UV has tripled. After that, our calculations for the health impacts start to break down because we’re getting so far into conditions that have never been seen before.”
The research team also found that more than half the treaty’s health benefits could be traced to the later amendments rather than the original 1987 Montreal Protocol. Overall, the treaty prevented more than 99% of potential health impacts that would have otherwise occurred from ozone destruction. This showed the importance of the treaty’s flexibility in adjusting to evolving scientific knowledge, the authors said.
The researchers focused on the U.S. because of ready access to health data and population projections. Lee-Taylor said that the specific health outcomes in other countries may vary, but the overall trends would be similar.
“The treaty had broad global benefits,” she said.
What is Boron?
The trace mineral boron provides profound anti-cancer effects, in addition to maintaining stronger bones.
Life Extension, September 2021
Boron is a trace mineral found in the earth’s crust and in water. Its importance in human health has been underestimated.
Boron has been shown to have actions against specific types of malignancies, such as:
Cervical cancer: The country Turkey has an extremely low incidence of cervical cancer, and scientists partially attribute this to its boron-rich soil.1 When comparing women who live in boron-rich regions versus boron-poor regions of Turkey, not a single woman living in the boron-rich regions had any indication of cervical cancer.2(The mean dietary intake of boron for women in this group was 8.41 mg/day.) Boron interferes with the life cycle of the human papillomavirus (HPV), which is a contributing factor in approximately 95% of all cervical cancers.1 Considering that HPV viruses are increasingly implicated in head and neck cancers,3,4 supplementation with this ultra-low-cost mineral could have significant benefits in protecting against this malignancy that is increasing in prevalence.
Lung cancer: A study conducted at the University of Texas MD Anderson Cancer Center between 1995 and 2005 found that increased boron intake was associated with a lower risk of lung cancer in postmenopausal women who were taking hormone replacement therapy.
Prostate cancer: Studies point to boron’s ability to inhibit the growth and spread of prostate cancer cells. In one study, when mice were exposed to boric acid, their tumors shrank by as much as 38%.6 One analysis found that increased dietary boron intake was associated with a decreased risk of prostate cancer.7
Several human and animal studies have confirmed the important connection between boron and bone health.
Boron prevents calcium loss,8 while also alleviating the bone problems associated with magnesium and vitamin D deficiency.9 All of these nutrients help maintain bone density.
A study in female rats revealed the harmful effects a deficiency in boron has on bones, including:10
Decreased bone volume fraction, a measure of bone strength,
Decreased thickness of the bone’s spongy inner layer, and
Decreased maximum force needed to break the femur.
And in a study of post-menopausal women, supplementation with3 mg of boron per day prevented calcium loss and bone demineralization by reducing urinary excretion of both calcium and magnesium.8
In addition to its bone and anti-cancer benefits, there are nine additional reasons boron is an important trace mineral vital for health and longevity. It has been shown to:1
Greatly improve wound healing,
Beneficially impact the body’s use of estrogen, testosterone, and vitamin D,
Boost magnesium absorption,
Reduce levels of inflammatory biomarkers, such as high-sensitivity C-reactive protein (hs-CRP) and tumor necrosis factor α (TNF-α),
Raise levels of antioxidant enzymes, such as superoxide dismutase (SOD), catalase, and glutathione peroxidase,
Protect against pesticide-induced oxidative stress and heavy-metal toxicity,
Improve the brain’s electrical activity, which may explain its benefits for cognitive performance, and short-term memory in the elderly,
Influence the formation and activity of key biomolecules, such as S-adenosyl methionine (SAM-e) and nicotinamide adenine dinucleotide (NAD+), and
Potentially help ameliorate the adverse effects of traditional chemotherapeutic agents.
Because the amount of boron varies in the soil, based on geographical location, obtaining enough boron through diet alone can be difficult.
Supplementing with low-cost boron is an effective way to maintain adequate levels of this overlooked micronutrient.

Natural compound in basil may protect against Alzheimer's disease pathology
University of South Florida, October 5, 2021
Fenchol, a natural compound abundant in some plants including basil, can help protect the brain against Alzheimer's disease pathology, a preclinical study led by University of South Florida Health (USF Health) researchers suggests.
The new study published Oct. 5 in the Frontiers in Aging Neuroscience, discovered a sensing mechanism associated with the gut microbiome that explains how fenchol reduces neurotoxicity in the Alzheimer's brain.
Emerging evidence indicates that short-chain fatty acids (SCFAs)– metabolites produced by beneficial gut bacteria and the primary source of nutrition for cells in your colon—contribute to brain health. The abundance of SCFAs is often reduced in older patients with mild cognitive impairment and Alzheimer's disease, the most common form of dementia. However, how this decline in SCFAs contributes to Alzheimer's disease progression remains largely unknown.
Gut-derived SCFAs that travel through the blood to the brain can bind to and activate free fatty acid receptor 2 (FFAR2), a cell signaling molecule expressed on brain cellscalled neurons.
"Our study is the first to discover that stimulation of the FFAR2 sensing mechanism by these microbial metabolites (SCFAs) can be beneficial in protecting brain cells against toxic accumulation of the amyloid-beta (Aβ) protein associated with Alzheimer's disease," said principal investigator Hariom Yadav, Ph.D., professor of neurosurgery and brain repair at the USF Health Morsani College of Medicine, where he directs the USF Center for Microbiome Research.
One of the two hallmark pathologies of Alzheimer's disease is hardened deposits of Aβ that clump together between nerve cells to form amyloid protein plaques in the brain. The other is neurofibrillary tangles of tau protein inside brain cells. These pathologies contribute to the neuron loss and death that ultimately cause the onset of Alzheimer's, a neurodegenerative disease characterized by loss of memory, thinking skills and other cognitive abilities.
Dr. Yadav and his collaborators delve into molecular mechanisms to explain how interactions between the gut microbiome and the brain might influence brain health and age-related cognitive decline. In this study, Dr. Yadav said, the research team set out to uncover the "previously unknown" function of FFAR2 in the brain.
The researchers first showed that inhibiting the FFAR2 receptor (thus blocking its ability to "sense" SCFAs in the environment outside the neuronal cell and transmit signaling inside the cell) contributes to the abnormal buildup of the Aβ protein causing neurotoxicity linked to Alzheimer's disease.
Then, they performed large-scale virtual screening of more than 144,000 natural compounds to find potential candidates that could mimic the same beneficial effect of microbiota produced SCFAs in activating FFAR2 signaling. Identifying a natural compound alternative to SCFAs to optimally target the FFAR2 receptor on neurons is important, because cells in the gut and other organs consume most of these microbial metabolites before they reach the brain through blood circulation, Dr. Yadav noted.
Dr. Yadav's team narrowed 15 leading compound candidates to the most potent one. Fenchol, a plant-derived compound that gives basil its aromatic scent, was best at binding to the FFAR's active site to stimulate its signaling.
Further experiments in human neuronal cell cultures, as well as Caenorhabditis (C.) elegans (worm) and mouse models of Alzheimer's disease demonstrated that fenchol significantly reduced excess Aβ accumulation and death of neurons by stimulating FFAR2 signaling, the microbiome sensing mechanism. When the researchers more closely examined how fenchol modulates Aβ-induced neurotoxicity, they found that the compound decreased senescent neuronal cells, also known as "zombie" cells, commonly found in brains with Alzheimer's disease pathology.
Zombie cells stop replicating and die a slow death. Meanwhile, Dr. Yadav said, they build up in diseased and aging organs, create a damaging inflammatory environment, and send stress or death signals to neighboring healthy cells, which eventually also change into harmful zombie cells or die.
"Fenchol actually affects the two related mechanisms of senescence and proteolysis," Dr. Yadav said of the intriguing preclinical study finding. "It reduces the formation of half-dead zombie neuronal cells and also increases the degradation of (nonfunctioning) Aβ, so that amyloid protein is cleared from the brain much faster."
Before you start throwing lots of extra basil in your spaghetti sauce or anything else you eat to help stave off dementia, more research is needed—including in humans.
In exploring fenchol as a possible approach for treating or preventing Alzheimer's pathology, the USF Health team will seek answers to several questions. A key one is whether fenchol consumed in basil itself would be more or less bioactive (effective) than isolating and administering the compound in a pill, Dr. Yadav said. "We also want to know whether a potent dose of either basil or fenchol would be a quicker way to get the compound into the brain."
Researchers find sense of purpose associated with better memory
Florida State University, October 6, 2021
Add an improved memory to the list of the many benefits that accompany having a sense of purpose in life.
A new study led by Florida State University researchers showed a link between an individual's sense of purpose and their ability to recall vivid details. The researchers found that while both a sense of purpose and cognitive function made memories easier to recall, only a sense of purpose bestowed the benefits of vividness and coherence.
The study, which focused on memories related to the COVID-19 pandemic, was published in the journal Memory.
"Personal memories serve really important functions in everyday life," said Angelina Sutin, a professor in the College of Medicine and the paper's lead author. "They help us to set goals, control emotions and build intimacy with others. We also know people with a greater sense of purpose perform better on objective memory tests, like remembering a list of words. We were interested in whether purpose was also associated with the quality of memories of important personal experiences because such qualities may be one reason why purpose is associated with better mental and physical health."
Nearly 800 study participants reported on their sense of purpose and completed tasks that measured their cognitive processing speed in January and February 2020, before the ongoing coronavirus pandemic took hold in the U.S. Researchers then measured participants' ability to retrieve and describe personal memories about the pandemic in July 2020, several months into the public health crisis.
Participants with a stronger sense of purpose in life reported that their memories were more accessible, coherent and vivid than participants with less purpose. Those with a higher sense of purpose also reported many sensory details, spoke about their memories more from a first-person perspective and reported more positive feeling and less negative feeling when asked to retrieve a memory.
The researchers also found that depressive symptoms had little effect on the ability to recall vivid details in memories, suggesting that the connection between life purpose and memory recall is not due to the fewer depressive symptoms among individuals higher in purpose.
Purpose in life has been consistently associated with better episodic memory, such as the number of words retrieved correctly on a memory task. This latest research expands on those connections to memory by showing a correlation between purpose and the richness of personal memory.
"We chose to measure the ability to recall memories associated with the COVID-19 pandemic because the pandemic is an event that touched everyone, but there has been a wide range of experiences and reactions to it that should be apparent in memories," said co-author Martina Luchetti, an assistant professor in the College of Medicine.
Along with the association with better memory, previous research has found other numerous benefits connected with having a sense of purpose, from a lower risk of death to better physical and mental health.
"Memories help people to sustain their well-being, social connections and cognitive health," said co-author Antonio Terracciano, a professor in the College of Medicine. "This research gives us more insight into the connections between a sense of purpose and the richness of personal memories. The vividness of those memories and how they fit into a coherent narrative may be one pathway through which purpose leads to these better outcomes.
Vitamin D protects against severe asthma attacks
Queen Mary University of London, October 3, 2021
Taking oral vitamin D supplements in addition to standard asthma medication could halve the risk of asthma attacks requiring hospital attendance, according to research led by Queen Mary University of London (QMUL).
Asthma affects more than 300 million people worldwide and is estimated to cause almost 400,000 deaths annually. Asthma deaths arise primarily during episodes of acute worsening of symptoms, known as attacks or 'exacerbations', which are commonly triggered by viral upper respiratory infections.
Vitamin D is thought to protect against such attacks by boosting immune responses to respiratory viruses and dampening down harmful airway inflammation.
The new study, funded by the National Institute for Health Research, and published in The Lancet Respiratory Medicine, collated and analysed the individual data from 955 participants in seven randomised controlled trials, which tested the use of vitamin D supplements.
Overall, the researchers found that vitamin D supplementation resulted in:
a 30 per cent reduction in the rate of asthma attacks requiring treatment with steroid tablets or injections - from 0.43 events per person per year to 0.30.
a 50 per cent reduction in the risk of experiencing at least one asthma attack requiring Accident and Emergency Department attendance and/or hospitalisation - from 6 per cent of people experiencing such an event to 3 per cent.
Vitamin D supplementation was found to be safe at the doses administered. No instances of excessively high calcium levels or renal stones were seen, and serious adverse events were evenly distributed between participants taking vitamin D and those on placebo.
Lead researcher Professor Adrian Martineau said: "These results add to the ever growing body of evidence that vitamin D can support immune function as well as bone health. On average, three people in the UK die from asthma attacks every day. Vitamin D is safe to take and relatively inexpensive so supplementation represents a potentially cost-effective strategy to reduce this problem."
The team's use of individual participant data also allowed them to query the extent to which different groups respond to vitamin D supplementation, in more detail than previous studies.
In particular, vitamin D supplementation was found to have a strong and statistically-significant protective effect in participants who had low vitamin D levels to start with. These participants saw a 55 per cent reduction in the rate of asthma exacerbations requiring treatment with steroid tablets or injections - from 0.42 events per person per year to 0.19.
However, due to relatively small numbers of patients within sub-groups, the researchers caution that they did not find definitive evidence to show that effects of vitamin D supplementation differ according to baseline vitamin D status.
Professor Hywel Williams, Director of the NIHR Health Technology Assessment Programme, said: "The results of this NIHR-funded study brings together evidence from several other studies from over the world and is an important contribution to reducing uncertainties on whether Vitamin D is helpful for asthma - a common condition that impacts on many thousands of people worldwide."
Dr David Jolliffe from QMUL, first author on the paper, added: "Our results are largely based on data from adults with mild to moderate asthma: children and adults with severe asthma were relatively under-represented in the dataset, so our findings cannot necessarily be generalised to these patient groups at this stage. Further clinical trials are on-going internationally, and we hope to include data from them in a future analysis to determine whether the promise of today's results is confirmed in an even larger and more diverse group of patients."
Study Shows Lifestyle Choices Have Significant Impact on Multiple Chronic Conditions, Significant Implications For Reducing Costs
Yale University, October 05, 2021
In a study published in the Journal of Preventive Medicine, Adams and colleagues showed a linear association between a number of modifiable risk factors and multiple chronic conditions, making those modifications a key to health care cost savings and to preventing a wide range of conditions.
The data analyzed for the study, https://authors.elsevier.com/a/1VpFeKt2pmc9H, were from the publicly available 2013 Behavioral Risk Factor Surveillance System and included 483,865 non-institutionalized US adults ages 18 years old or older. Chronic conditions included asthma, arthritis, heart disease, stroke, chronic obstructive pulmonary disease (COPD), cognitive impairment, cancer other than skin, and kidney disease. Risk factors included obesity, current smoking, sedentary lifestyle, inadequate fruit and vegetable consumption and sleeping other than seven to eight hours, while depression, hypertension, high cholesterol, and diabetes were considered in each category.
Previous research by Thorpe and colleagues had estimated that the care of adults with four or more chronic conditions (17.1% of all adults in the study) is responsible for 77.6% of all health care costs in the U.S. today.
The potential savings by reducing just two risk factors (diabetes and hypertension) and their related comorbidity was estimated previously by Ormond and colleagues at $9 billion annually over one to two years and closer to $25 billion a year after 5 years or more, factoring in possible complications.
True Health Initiative founder, at Yale University Director and study co-author David L. Katz, MD, MPH, FACLM, pointed out that in addition to costs, another implication of the study results is an individual's access to healthcare if they have one or more of the chronic conditions.
"Although insurers decide what qualifies as a pre-existing condition, all the chronic conditions used in this study except cognitive impairment are commonly included," he said. "Individuals with a pre-existing condition could be denied coverage or face higher premiums. While having a pre-existing condition might not affect coverage for adults eligible for Medicare, over half of all adults with multiple chronic conditions are ages 18 to 64 years."
American College of Lifestyle Medicine President George Guthrie, MD, MPH, FACLM, said the study confirms the necessity for addressing the root cause of chronic conditions.
"The evidence shows that the risks for chronic disease are rooted in lifestyle choices," he said. "More than ever, it is important to emphasize lifestyle medicine as the first treatment option for preventing, treating, and in some cases, reversing the cause of chronic conditions. If we can help people with chronic conditions, we can add years to their life and life to their years, as well as lower the ever-increasing costs of healthcare for everyone."
Physical athletes' visual skills prove sharper than action video game players
University of Waterloo (Canada), October 7, 2021
Athletes still have the edge over action video gamers when it comes to dynamic visual skills, a new study from the University of Waterloo shows.
For an athlete, having strong visual skills can be the difference between delivering a peak performance and achieving average results.
"Athletes involved in sports with a high-level of movement—like soccer, football, or baseball—often score higher on dynamic visual acuity tests than non-athletes," said Dr. Kristine Dalton of Waterloo's School of Optometry & Vision Science. "Our research team wanted to investigate if action video gamers—who, like e-sport athletes, are regularly immersed in a dynamic, fast-paced 2D video environment for large periods of time—would also show superior levels of dynamic visual acuity on par with athletes competing in physical sport."
While visual acuity (clarity or sharpness of vision) is most often measured under static conditions during annual check-ups with an optometrist, research shows that testing dynamic visual acuity is a more effective measure of a person's ability to see moving objects clearly—a baseline skill necessary for success in physical and e-sports alike.
Using a dynamic visual acuity skills-test designed and validated at the University of Waterloo, researchers discovered that while physical athletes score highly on dynamic visual acuity tests as expected, action video game players tested closer to non-athletes.
"Ultimately, athletes showed a stronger ability to identify smaller moving targets, which suggests visual processing differences exist between them and our video game players," said Alan Yee, a Ph.D. candidate in vision science. All participants were matched based on their level of static visual acuity and refractive error, distinguishing dynamic visual acuity as the varying factor on their test performance.
These findings are also important for sports vision training centers that have been exploring the idea of developing video game-based training programs to help athletes elevate their performance.
"Our findings show there is still a benefit to training in a 3D environment," said Dalton. "For athletes looking to develop stronger visual skills, the broader visual field and depth perception that come with physical training may be crucial to improving their dynamic visual acuity—and ultimately, their sport performance."
The study, Athletes demonstrate superior visual dynamic visual acuity, authored by Waterloo's School of Optometry & Vision Science's Dalton, Yee, Dr. Elizabeth Irving and Dr. Ben Thompson, was recently published in the journal Optometry and Vision Science.
Probiotic Akkermansia muciniphila and environmental enrichment reverse cognitive impairment associated with high-fat high-cholesterol consumption
University of Oviedo (Spain), September 8, 2021
Nonalcoholic steatohepatitis (NASH) is one of the most prevalent diseases globally. A high-fat, high-cholesterol (HFHC) diet leads to an early NASH model. It has been suggested that gut microbiota mediates the effects of diet through the microbiota–gut–brain axis, modifying the host’s brain metabolism and disrupting cognition. Here, we target NASH-induced cognitive damage by testing the impact of environmental enrichment (EE) and the administration of either Lacticaseibacillus rhamnosus GG (LGG) or Akkermansia muciniphila CIP107961 (AKK). EE and AKK, but not LGG, reverse the HFHC-induced cognitive dysfunction, including impaired spatial working memory and novel object recognition; however, whereas AKK restores brain metabolism, EE results in an overall decrease. Moreover, AKK and LGG did not induce major rearrangements in the intestinal microbiota, with only slight changes in bacterial composition and diversity, whereas EE led to an increase in Firmicutes and Verrucomicrobia members. Our findings illustrate the interplay between gut microbiota, the host’s brain energy metabolism, and cognition. In addition, the findings suggest intervention strategies, such as the administration of AKK, for the management of the cognitive dysfunction related to NASH.
In this study, we described cognitive, brain metabolism, and microbiota alterations associated with high-fat and high-cholesterol consumption. In addition, we clearly showed that environmental enrichment and A. muciniphila CIP107961 restore cognitive dysfunction. Furthermore, we revealed that cognitive improvement is associated with differential effects of environmental enrichment and this strain of A. muciniphila on brain metabolism and gut microbiota. Finally, we discovered that restored cognitive function was associated with the administration of A. muciniphila CIP107961, but not L. rhamnosus GG, which may be clinically relevant when selecting probiotics for treating HFHC-derived pathologies.
In conclusion, the microbiota and cognition are intimately connected through the gut–brain axis, and in HFHC pathologies they can be influenced by environmental enrichment and A. muciniphila CIP107961 administration. Cognitive improvement was accompanied by changes in brain metabolic activity and gut microbial composition analysis, pointing to specific microbiota targets for intervention in diet-induced pathologies. However, some mechanisms other than major changes in microbiota composition and the combined effect of environmental enrichment and A. muciniphila administration, which we identified in this study, may also be biologically relevant and will need to be investigated in future studies due to their relative contributions to the selection of effective treatments for patients.

Red onion effective at killing cancer cells, study says
University of Guelph (Ontario)
If you’re looking for a flavorful way to help fight and prevent cancer, add red onion to your shopping list. It will be worth the effort … as you will soon see why.
In the first study of its kind, University of Guelph researchers looked at how the Ontario-grown red onion and several others affected the growth and proliferation of cancer cells. Their findings indicate that all onions are not created equal.
The Canadian researchers looked at five different kinds of onion in total from the province of Ontario. They assessed the onions in terms of their effects against cancer cells and their ability to prevent cancer. Of the five species tested, the Ruby Ring red onion was the most effective.
Few people are aware that onions are somewhat of a superfood. Hopefully, studies like these will help to change that. Onions in general have very high concentrations of the flavonoid quercetin. However, the Ruby Ring Ontario red onion has particularly high levels of these compounds as compared with other species.
In the study, colon cancer cells were placed in direct contact with quercetin that was extracted from the five onion varieties studied. It was found that all of the onion types created an unfavorable environment for cancer cells and initiated cancer cell death, or apoptosis. Communication between the cancer cells seems to be disrupted by the compounds in the onions, and this can help to fight and prevent cancer.
The study also showed that the Ruby Ring red onion was high in anthocyanin, a compound that helps to enrich the scavenging properties of quercetin. This in turn supports quercetin in fighting cancer cells and helping to prevent cancer.
Anthocyanin is the molecule that gives vegetables like red onions their rich, deep color. This is in keeping with the general increased healthbenefits that can be gained from other dark or brightly colored vegetables and fruits. The recent onion study results were published in the journal Food Research International.
While all of the onions studied showed the ability to inhibit cancer cells, red onions were particularly effective. Their beneficial compounds blocked the production of both colon cancer cells and breast cancer cells within the controlled conditions of the study.
The next step is to complete human trials to further explore the cancer fighting effects of onions. Researchers are also working on an extraction technique to isolate the quercetin in onions so that it can be administered as a cancer therapy.
In the meantime, finding ways to include more of this cancer-fighting superfood into your diet can allow you to experience many health benefits. Enjoy red onions in salads, on sandwiches and cooked into soups, stews and stir-fry dishes.
Age and aging have critical effects on the gut microbiome
Cedars-Sinai Medical Center, October 4, 2021
Researchers at Cedars-Sinai have found that aging produces significant changes in the microbiome of the human small intestine distinct from those caused by medications or illness burden. The findings have been published in the journal Cell Reports.
"By teasing out the microbial changes that occur in the small bowel with age, medication use and diseases, we hope to identify unique components of the microbial community to target for therapeutics and interventions that could promote healthy aging," said Ruchi Mathur, MD, the study's principal investigator.
Research exploring the gut microbiome, and its impact on health, has relied predominantly on fecal samples, which do not represent the entire gut, according to Mathur. In their study, investigators from Cedars-Sinai's Medically Associated Science and Technology (MAST) Program analyzed samples from the small intestine–which is over 20 feet in length and has the surface area of a tennis court–for examination of the microbiome and its relationship with aging.
"This study is the first of its kind to examine the microbial composition of the small intestine of subjects 18 years of age to 80. We now know that certain microbial populations are influenced more by medications, while others are more affected by certain diseases. We have identified specific microbes that appear to be only influenced by the chronological age of the person," said Mathur, an endocrinologist and director of the Diabetes Outpatient Treatment & Education Center.
The 21st century has been referred to as the "era of the gut microbiome" as scientists turn considerable attention to the role trillions of gut bacteria, fungi and viruses may play in human health and disease. The microbiome is the name given to the genes that live in these cells. Studies have suggested that disturbances in the constellations of the microbial universe may lead to critical illnesses, including gastroenterological diseases, diabetes, obesity, and some neurological disorders.
While researchers know that microbial diversity in stool decreases with age, Cedars-Sinai investigators identified bacteria in the small bowel they refer to as "disruptors" that increase and could be troublesome.
"Coliforms are normal residents of the intestine. We found that when these rod-shaped microbes become too abundant in the small bowel–as they do as we get older–they exert a negative influence on the rest of the microbial population. They are like weeds in a garden," said study co-author Gabriela Leite, Ph.D.
Investigators also found that as people age, the bacteria in the small intestine change from microbes that prefer oxygen to those that can survive with less oxygen, something they hope to understand as the research continues.
"Our goal is to identify and fingerprint the small intestinal microbial patterns of human health and disease. Given the important role the small bowel plays in absorption of nutrients, changes in the microbiome in this location of the gut may have a greater impact on human health, and warrants further study," said Mark Pimentel, MD, director of the MAST program and a co-author of the study.
This research is part of Cedars-Sinai's ongoing REIMAGINE study: Revealing the Entire Intestinal Microbiota and its Associations with the Genetic, Immunologic, and Neuroendocrine Ecosystem.
Study finds no association between caffeine intake and invasive breast cancer risk
University of Buffalo, September 28, 2021
Researchers from the University at Buffalo conducted a study of nearly 80,000 postmenopausal women in the U.S. to determine whether caffeine consumption from coffee and tea has any association with invasive breast cancer.
The average age when U.S. women reach menopause, 51, also happens to coincide with the age group—50- to 64-year-olds—that has the highest reported caffeine consumption. In addition to that, the average age of breast cancer diagnosis in the U.S. is 62.
This overlap of age at menopause, age at diagnosis of breast cancer and age with high caffeine consumption gave greater weight to the importance of clarifying whether caffeine intake impacts breast cancer risk in postmenopausal women.
It does not, according to the UB researchers' findings, published in August in the International Journal of Cancer.
"From our literature review, many studies have found significant associations between coffee and/or tea consumption and reduced breast cancer incidence whereas a few studies have reported elevated risk. Our study, however, found no association," said study first author Christina KH Zheng, who worked on the study while completing her master's in epidemiology at UB. She is now a surgical resident in the MedStar Baltimore general surgery program.
"About 85% of Americans drink at least one caffeinated beverage a day. It is important for the public to know whether consumption of caffeinated beverages has beneficial or harmful effects on breast cancer, the most common type of cancer and second-leading cause of cancer death for U.S. women," said Lina Mu, MD, Ph.D., the study's senior author, who is an associate professor of epidemiology and environmental health at UB.
"The overlap of age at diagnosis of breast cancer and age with high consumption of caffeine, and the inconsistent findings from previous studies motivated us to study whether this lifestyle factor could affect breast cancer risk in postmenopausal women," said Kexin Zhu, a study co-first author and epidemiology Ph.D. student in UB's School of Public Health and Health Professions.
Researchers looked at a sample of 79,871 participants in the Women's Health Initiative Observational Study. Participants have for decades now completed yearly health questionnaires that help researchers learn more about diet and exercise habits, as well as disease, and any possible linkages.
After a median follow-up of 16 years, there were 4,719 cases of invasive breast cancer identified.
At first glance, women who reported drinking two to three cups of caffeinated coffee per day had a 12% higher risk of invasive breast cancer compared to non-drinkers. But that association was not statistically significant after adjusting for lifestyle factors, such as smoking and alcohol consumption.
"Seeing null results after adjusting for lifestyle, demographic and reproductive factors informs us of the complexity that is the relationship between caffeine intake and invasive breast cancer risk," Zheng said.
"Some lifestyle factors, like drinking alcohol and physical activity, might be associated with both coffee intake and breast cancer risk," Zhu explained. "Therefore, they might confound the initial positive associations. After we took the lifestyle factors into account, the results suggested that regular coffee drinking might not have an impact on invasive breast cancer risk."
The risk of invasive breast cancer was even higher—22%—for women who reported drinking two to three cups of decaffeinated coffee each day. It was slightly lower when adjusted for lifestyle variables (smoking history, alcohol consumption, physical activity, etc.), and the association was not statistically significant when further accounting for reproductive variables such as family history of breast cancer and number of children
The researchers were unable to determine if the elevated risk is due to the decaffeinated nature of the coffee, the amount consumed, or another factor unique to this population that was not accounted for in the study.
The researchers did not observe a significant association between overall tea consumption and invasive breast cancer. Additional research needs to be done in order to understand whether different types of teas have different effects on breast cancer risk, Zhu said.
Liver function improves with the consumption of Broccoli sprout extract
Tokai University Tokyo Hospital (Japan), October 5, 2021
A Japanese study of broccoli sprouts and liver function has found the sulforaphane-rich food to be highly beneficial. An extract from broccoli sprouts given to male participants was shown to improve hepatic abnormalities and overall liver function significantly.
For the study, the researchers conducted a double blind, randomized placebo-controlled trial of males with fatty liver disease. The subjects received either extract of broccoli sprouts in capsule form, or a placebo. The capsules contained glucoraphanin, a precursor for the sulforaphane in broccoli sprouts.
A number of key liver function markers were measured before and after the trial. It was determined that dietary supplementation with extract of broccoli improved liver functioning by decreasing alkali phosphatase activity and oxidative stress markers.
Broccoli sprout extract was also found to prevent NDMA-induced chronic liver failure in rats. The researchers believe the antioxidants in broccoli sprouts are effective in suppressing the mechanisms of liver failure at a cellular level.
The reduction of oxidative stress is crucial in protecting the liver and improving its health, and broccoli is loaded with health-supporting antioxidants.
Non-alcoholic fatty liver disease (NAFLD) is also reaching epidemic proportions, with nearly 30 percent of Americans (90 million people) having some level of the disease. Like hep C, NAFLD can result in liver failure and cancer of the liver in the most severe cases.
Exposure to environmental toxins exacerbates liver conditions as well, with the glyphosate found in weed killers, like Roundup, particularly harmful.
The good news is that liver conditions are preventable by embracing a healthy lifestyle. Eating plenty of organic fruits and vegetables, exercising regularly and avoiding alcohol and cigarettes can do wonders for liver health.
As evidenced by the recent research out of Japan, sulforaphane-rich broccoli sprouts can be a key component in supporting healthy liver function. Milk thistle, vitamin E, black seed oil and dandelion root have also shown effectiveness in supporting and detoxifying the liver.
How cannabis-like substances keep the brain in balance
Utrecht University (Netherlands), October 4, 2021
Whenever we learn, remember or forget something, a surprisingly active role is played by cannabis-like substances in the brain. Researchers at Utrecht University found that the substances actively balance connections in the brain that allow cells to either activate or inhibit each other. The discovery reveals how brain cells influence each other, and how psychiatric disorders can arise when this process goes wrong.
Although wisdom comes with age, our brain does not store every single experience or lesson learned. In addition to learning and remembering, our brains are also equipped to forget irrelevant things or drop unused skills. In order to find a balance in this, brain cellsconstantly communicate with each other through connections that activate or inhibit the cells. Researchers from Utrecht University discovered that brain cells can form new, inhibitory connections via so-called endocannabinoids. They reported their discovery in Journal of Neuroscience.
Counterbalance
Endocannabinoids derive their name from the cannabis plant, which contains similar substances. The researchers discovered the role of endocannabinoids when they induced brain cells of mice to strengthen activating connections. In response, the brain cells also started making new inhibitory connections. The researchers found that endocannabinoids kickstarted the new connections.
Surprisingly active role
The researchers were surprised to find that these substances play such an active role. "Nobody expected this from endocannabinoids," says research leader Dr. Corette Wierenga, neurobiologist at Utrecht University.
It was already known that endocannabinoids can influence the functioning of our brains. But until now researchers assumed that the substances were merely involved in adjusting existing connections. "Now it appears that the system of endocannabinoids can actively push the production of new inhibitory connections, with which brain cells actively regulate the balance."
Psychiatric disorders caused by imbalance
The discovery could help scientists to better understand how psychiatric disordersand other abnormalities in the brain develop. In many of these disorders, the balance between inhibitory and activating connections is disturbed. During an epileptic seizure, for example, this balance is seriously disturbed. Although in many other disorders the disturbance is more subtle, for example in schizophrenia, the impact can still be equally profound.
Cannabis-related unbalance
The balance between activating and inhibiting connections in our brain is constantly being adjusted in response to our experiences. Whenever we experience something, the connections change, and the brain must restore the balance. Cannabis use can disrupt that balance.
"Occasional cannabis use will not seriously disturb the balance," says Wierenga. "But if the balance is disturbed for a longer period, it can cause problems. For example, children of mothers who smoked marijuana during pregnancy can experience problems with neurological development."
Early stages of life
The balance is especially important in early stages of life, Wierenga says. "During our development, brain connections are constantly changing. Especially during that period, it is important that inhibitory and activating connections remain coordinated. If the coordination is malfunctioning or disturbed, you can imagine that the system becomes disrupted. And unfortunately, disruptions that occur so early cannot be easily repaired later in life."
According to Wierenga, such disruptions can lead not only to loss of memory, but also initiate more serious consequences. For example, the brain might grow out to less adaptive to stressful situations. "When this happens, things get out of hand more easily in the brain, because inhibition and activation are out of balance. That could lead to learning and behavioral problems."
Predicting and preventing disorders
Creating a deeper understanding of the role endocannabinoids play in the brain, could lead to psychiatric disorders being more predictable or even prevented in the future. The publication in Journal of Neuroscience now sets out a new direction in which more knowledge can be built up. Wierenga: "Ultimately, as a researcher, we want to understand how brain cells coordinate the balance and what happens when that balance is disturbed.
Glycerin is safe, effective in psoriasis model
Medical College of Georgia at Augusta University, October 4, 2021
Patients with psoriasis have reported that glycerin, an inexpensive, harmless, slightly sweet liquid high on the list of ingredients in many skin lotions, is effective at combatting their psoriasis and now scientists have objective evidence to support their reports.
They found that whether applied topically or ingested in drinking water, glycerin, or glycerol, helps calm the classic scaly, red, raised and itchy patches in their psoriasismodel, Dr. Wendy Bollag, cell physiologist and skin researcher at the Medical College of Georgia and Charlie Norwood VA Medical Center and her colleagues report in the International Journal of Molecular Sciences.
The studies also provide more evidence of the different ways glycerin enables the healthy maturation of skin cells through four stages that result in a smooth, protective skin layer. Psoriasis is an immune-mediated problem that typically surfaces in young adults in which skin cells instead multiply rapidly, piling up into inflamed patches.
"We have experimental data now to show what these patients with psoriasis are reporting," says Bollag, who nearly 20 years ago first reported in The Journal of Investigative Dermatology that glycerin, a natural alcohol and water attractor known to help the skin look better, also safely helped it function better by helping skin cells mature properly.
Bollag's early report led to many anecdotal reports from individuals and their reports ultimately led to the newly published study.
Topically, glycerin is known to have a soothing, emollient effect. But another key part of its magic, which Dr. Bollag has helped delineate, is its conversion to the lipid, or fat, phosphatidylglycerol, which ultimately regulates the function of keratinocytes, our major skin cell type, and suppresses inflammation in the skin.
Glycerin gets into the skin through avenues like aquaporin-3, a channel expressed in skin cells, and the MCG scientists have shown that once inside, aquaporin 3 funnels glycerin to phospholipase-D-2, an enzyme that converts fats in the external cell membrane into cell signals, ultimately converting glycerin to phosphatidylglycerol.
In 2018, Bollag and team reported that topical application of phosphatidylglycerol reduced inflammation and the characteristic raised skin patches in a mouse model of psoriasis. This time they decided to look at the impact of its widely available precursor glycerin.
For the new studies, they used imiquimod, which is known to produce psoriasis-like plaques on humans using it for problems like genital warts and some skin cancers, to produce an animal model. The mice either drank the sweet natural alcohol or the scientists applied it topically. Either way, glycerin helped reduce development of the characteristic skin lesions, the scientists report, a finding which helps underline that glycerin works in more than one way to improve the skin condition.
Externally, glycerin showed its action as an emollient because even in mice missing phospholipase-D-2, it was beneficial. Additionally, topically it appears to compete with hydrogen peroxide for space inside the aquaporin 3 channel. Hydrogen peroxide is commonly known as a mild antiseptic but we produce it as well and at low levels it's a cell signaling molecule. But at high levels, hydrogen peroxide produces destructive oxidative stress, which can actually cause psoriasis.
The scientists found that topical glycerin reduced the levels of hydrogen peroxide entering skin cells. When they added glycerin and hydrogen peroxide at the same time directly to skin cells, they found that glycerin protected against the oxidative stress from hydrogen peroxide.
"Glycerol is basically outcompeting the hydrogen peroxide in getting in there and preventing it from being able to enter and increase oxidative stress," Bollag says. Oil and water don't mix, so yet another way glycerin may be helpful is by supporting the skin's major role as a water permeability barrier so that, as an extreme, when we sit in a bathtub the bath water doesn't pass through our skin so we blow up like a balloon, she says.
On the other hand, when glycerin was ingested by the mice missing the phospholipase- D-2, which converts fats or lipids in a cell's membrane to signals, it simply did not work, Bollag says, which confirmed their earlier findings that internally anyway, glycerin pairs with the enzyme to produce the signal essential to skin cell maturation.
Some of their other most recent work is detailing more about how phosphatidylglycerol decreases inflammation.
Bollag would like next steps to also include clinical trials with dermatologists and patients and is working to find a formulation scientist who can make what she thinks will be the optimal combination: glycerin and phosphatidylglycerol in the same topical cream.
The addition of phosphatidylglyerol itself, rather than just the glycerin that makes it, is essentially a backup since there is some evidence that in psoriasis the essential conversion of glycerin to phosphatidylglycerol is not optimal. Bollag's lab and others have shown reduced levels of aquaporin 3 in psoriasis, which likely means less phosphatidylgycerol, so making more glycerin available may help, albeit not as efficiently, raise the availability of this lipid essential to normal skin cell proliferation.
Moving quickly into clinical trials should be comparatively easy since, as with glycerin, there already is experience with the use of phosphatidylglycerol in humans. For example, it's a component of some high-end cosmetics, Bollag says.
She suspects that this sort of two-punch combination, could help keep early signs of psoriasis at bay and, with more advanced disease, use existing psoriasis treatments to get the skin condition under control then start applying glycerin to help keep it that way.
Bollag and her colleagues reported in 2018 in the Journal of Investigative Dermatology that in a mouse model of psoriasis, phosphtidylglycerol reduced inflammation and the characteristic raised skin lesions of psoriasis.
While its exact cause is unclear, psoriasis is an immune-mediated condition and patients have higher levels of inflammation, as well as too many skin cells being produced then maturing abnormally. The heightened inflammation also puts them at increased risk for problems like heart disease.
Biologics used to treat psoriasis work different ways to stem this overactive immune response but in addition to their high cost, can put the patient at risk for problems like serious infections and cancer. The only side effect she has seen in about 20 years of working with glycerin and the clinical and cosmetic use already out there, is it can leave the skin feeling slightly sticky.
Our bodies can make glycerol from the carbohydrates, proteins and fats that we eat or already have in our body.
