Influence of a Novel Food-Grade Formulation of Red Chili Extract on Overweight Subjects
St. Thomas College (India), September 12 2020
Abstract

Capsaicinoids from pungent red chilies (Capsicum annum and Capsicum frutescens) have received significant attention as a natural supplement for the management of obesity. However, the consumption of chili extract at physiologically relevant dosage of capsaicinoids is a challenge owing to its pungency and gastrointestinal discomforts. The present study reports the systemic absorption, safety and influence of a novel, food-grade, and sustained-release formulation of capsaicinoids-rich red chili extract using fenugreek dietary fiber (Capsifen®). Twenty-four healthy overweight subjects were randomized into placebo (n = 12) and Capsifen (n = 12) groups and supplemented with 200 mg × 1/day of Capsifen (4 mg capsaicinoids/day) for 28 days. Influence of Capsifen on eating behavior and appetite was followed by Three-Factor Eating Questionnaire (TFEQ) and Council of Nutrition Appetite Questionnaire (CNAQ), respectively. Consumption of Capsifen did not reveal any adverse events or deviations in hematology and biochemical parameters related to safety. However, a significant decrease in body weight (2.1%), w/h ratio (4%) and body mass index (BMI) (2.2%) were observed among Capsifen group when compared to placebo. The TFEQ and appetite analysis revealed a significant improvement in uncontrolled eating and reduction in appetite among Capsifen subjects. The UPLC-ESI-MS/MS analysis confirmed the absorption of capsaicinoids from CAP supplementation. The study further demonstrated the safety and tolerability of Capsifen at the investigational dosage. Thus, the significant reduction in anthropometric parameters such as body weight, w/h ratio, and BMI along with the improvement in eating behaviour as well as appetite, indicated the potential body weight management effect of Capsifen.

 

Study on the effect of rosemary and ginger essential oils against Klebsiella pneumoniae

 
Damanhour University and  Pharos University (Egypt), September 21, 2020
 

Klebsiella pneumoniae is a nosocomial pathogen in outbreaks of hospital infections. It is one of the major factors for morbidity and mortality in hospitalized patients especially those infected with colistin resistant pathogens. Many plant essential oils have antimicrobial activities and have been investigated as natural sources to combat multiple antibiotic resistances. Moreover; recent advances in phytonanotechnology have created exciting opportunities for the management of many infections. 

This study aims at investigating the antimicrobial and antibiofilm effect of rosemary and ginger essential oil-based nano-sized formulations on colistin resistant K. pneumonia clinical isolates.

Isolation and identification of 30 K. pneumonia isolates from different human samples was done followed by antibiotic susceptibility testing and detection of biofilm gene (mrkD). Examination of the activity of the tested essential oils and their chitosan nanoparticle formulations against the selected isolates was made by determination of their MICs using broth microdilution method followed by biofilm inhibition test and quantitative real-time PCR for the expression of mrkD gene in the presence of the oils and nanoparticles formulations compared to untreated bacterial isolates.

Our results showed that the minimum inhibitory concentrations of rosemary and ginger oils were found to be 1250 μg/ml, nanostructured lipid carrier-rosemary oil and nanostructured lipid carrier-ginger oil were 625 μg/ml and rosemary oil loaded chitosan nanoparticles and ginger oil loaded chitosan nanoparticles were 156 μg/ml. Results also revealed complete (100%) inhibition for mrkD gene expression when compared to untreated K. pneumonia. 

We can conclude that oil loaded chitosan nanoparticles show a high antimicrobial and antibiofilm activity.

 

 

The unintended consequence of becoming empathetic

University of Michigan, September 16, 2020

When people say that they want to change things about their personalities, they might not know about the inadvertent consequences these changes could bring. In fact, changes in personality may also lead to changes in political ideologies, say researchers from Michigan State University and the University of Granada, who led the study.

"We found this interesting effect where people wanted to improve on things like being more emotionally connected to others -- or, becoming more empathetic," said William Chopik, assistant professor of psychology at MSU. "But we found that this leads to changes in their political souls as well, which maybe they weren't intending. We saw that in these personality changes toward greater empathy, people placed a lot more importance upon more liberal ideologies -- like how you should treat other people and take others' perspectives."

The study, published in the most recent edition of Journal of Research in Personality, is the first to look at shifts in personalities and morals due to volitional change -- or, changes one brings upon oneself.

Chopik and co-authors from Southern Methodist University and the University of Illinois asked 414 volunteer participants to take a weekly questionnaire. Such questions included how they would react in certain situations, if they wanted to improve or change themselves, how they felt about helping others and other personality-related queries. Additionally, the researchers measured participants' "empathic concern" -- or, feelings that would arise when they saw someone in need or doing poorly. The researchers continued the weekly questionnaire for four months.

"Among the questions, we asked participants how they felt about five broad moral foundations: care, fairness, loyalty, authority and purity. We tracked sentiments week-to-week," Chopik said. "While these are common for personality-related assessments, individual moral foundations can also help explain attitudes toward various ideologies, ethical issues and policy debates."

Generally, liberal and progressive people tend to prioritize two of the five moral foundations: care and fairness; whereas, conservatives draw from all five -- including the more binding foundations: loyalty to the ingroup, respect for authority, and observance of purity and sanctity standards, Chopik said.

"Our study shows that when people are motivated to change, they can successfully do so," he said. "What we were surprised to find was that an upward trajectory for something like perspective-taking aligned with the person's shift towards the more liberal foundations."

The researchers did not intend for their study to generalize personality traits of one political party or another, but rather to see if -- and how -- a person could change themselves and what might be a result of their "moral transformation."

"Being a better perspective-taker exposes you to all sorts of new ideas, so it makes sense that it would change someone because they would be exposed to more diverse arguments," Chopik said. "When you become more empathic, it opens up a lot of doors to change humans in other ways, including how they think about morality and ideology -- which may or may not have been intended."

 

 

Evidence for Korean Ginseng's effects on improving bone health

Hospital of Chonbuk National University, Sept. 9, 2019

The Korea Ginseng Association introduced new evidence of Korean Ginseng's efficacy on bone health.

Korean Ginseng refers to ginsengs produced in Korea. Ginseng's scientific name, Panax ginseng, is named after the Greek word 'Panax', meaning cure for all diseases; indeed, ginseng has been sought after medicine since the ancient times. It has been proven to improve immune system and fatigue previously, and now even for bone health, as seen in recent research released in Korea.

In June of 2019, Rural Development Administration, Korea Research Institute of Bioscience & Biotechnology (KRIBB) and Hospital of Chonbuk National University confirmed the efficacy of Korean ginseng's efficacy on bone health in a research conducted for 3 years and followed up for another two years. The clinical application study was performed with three groups of female participants over the age of 40 and who suffer from bone loss. There were a total of 90 participants, with 30 participants in each group. The participants in the control group were given placebo, while the other groups were given ginseng extracts (3g per day and 1g per day). 

The results indicated that the level of osteocalcin was 11.6 times higher in the test group than the control group; the level of calcium was 3 times higher in the test group with 3g extracts as well. The change in Osteoarthritis rating before and after taking the extract was also significant, indicating ginseng's efficacy on improving pain and rigidity due to bone loss. 

In animal testing, ginseng extract (300mg per kg of mouse body mass) was administered for 8 weeks in Panax that were 112 weeks old. The result also indicated that bone density was 32% higher in the test group. The calcium concentration and bone formation effect were also higher in the test group. 

The Korea Ginseng Association's president Mr. Ban mentioned, "With this new evidence on ginseng's efficacy on bone health, we have even more pride for our Korean Ginseng. We hope to continue to find scientifically based evidence for the ginseng's benefits."

 
 

Immune system may have another job—combatting depression

Yale University, September 18, 2020

An inflammatory autoimmune response within the central nervous system similar to one linked to neurodegenerative diseases such as multiple sclerosis (MS) has also been found in the spinal fluid of healthy people, according to a new Yale-led study comparing immune system cells in the spinal fluid of MS patients and healthy subjects. The research, published Sept. 18 in the journal Science Immunology, suggests these immune cells may play a role other than protecting against microbial invaders—protecting our mental health.

The results buttress an emerging theory that gamma interferons, a type of immune cell that helps induce and modulate a variety of immune system responses, may also play a role in preventing depression in healthy people.

"We were surprised that normal spinal fluid would be so interesting," said David Hafler, the William S. and Lois Stiles Edgerly Professor of Neurology, professor of immunobiology and senior author of the study.

Previous research has shown that blocking gamma interferons and the T cells they help produce can cause depression-like symptoms in mice. Hafler notes that depression is also a common side effect in patients with MS treated with a different type of interferon.

Using a powerful new technology that allows a detailed examination of individual cells, the researchers show that while the characteristics of T cells in the spinal fluid of healthy people share similarities with those of MS patients, they lack the ability to replicate and cause the damaging inflammatory response seen in autoimmune diseases such as MS.

In essence, the immune system in the brains of all people is poised to make an inflammatory immune system response and may have another function than defending against pathogens, Hafler said.

"These T cells serve another purpose and we speculate that they may help preserve our mental health," he said.

Hafler said that his lab and colleagues at Yale plan to explore how immune system responses in the central nervous system might affect psychiatric disorders such as depression.

 

Avocado pulp improves cardiovascular and autonomic recovery following submaximal running

Sao Paulo State University (Brazil), August 23, 2020

Abstract

Previous studies have demonstrated that regular avocado consumption presents advantageous effects on cardiovascular system. However, little attention has been paid to the use of avocado as a dietary supplement, in particular, for individuals involved in physical exercise training. Therefore, this study aims to evaluate the effect of acute avocado pulp intake on cardiovascular and autonomic recovery subsequent to moderate exercise. Using a crossover, randomized, double-blind and placebo-controlled trial design, 16 healthy female adults underwent two protocols: Avocado pulp (600 mg in capsule) and placebo (600 mg starch in capsule). After the ingestion of Avocado pulp or placebo, the subjects were seated for 60 min at rest, followed by running on a treadmill at a submaximal level and then remained seated for 60 min during recovery from the exercise. Heart rate (HR), heart rate variability (HRV) [rMSSD, SD1, HF (ms2)] and skin conductance were evaluated before and during exercise, as well as during recovery. HR, systolic blood pressure, HRV and skin conductance recovered faster when subjects were given avocado pulp prior to exercise. In conclusion, avocado pulp improved cardiovascular and autonomic recovery after exercise, suggesting a reduced risk of cardiovascular events after exertion. The current results support the beneficial effects of ingestion of avocado prior to submaximal treadmill running.

 

Study shows vitamin E needed for proper nervous system development

Oregon State University, September 21, 2020

 

In research with key ramifications for women of childbearing age, findings by Oregon State University scientists show that embryos produced by vitamin E-deficient zebrafish have malformed brains and nervous systems.

"This is totally amazing - the brain is absolutely physically distorted by not having enough vitamin E," said Maret Traber, a professor in the OSU College of Public Health and Human Sciences.

The study led by Traber, the Ava Helen Pauling Professor at Oregon State's Linus Pauling Institute, was published today in Scientific Reports.

Zebrafish are a small freshwater species that go from a fertilized egg to a swimming fish in about five days. They are highly prized for studying the development and genetics of vertebrates. 

Zebrafish share a remarkable similarity to humans at the molecular, genetic and cellular levels, meaning many findings are immediately relevant to humans. Embryonic zebrafish are of special interest because they develop quickly, are transparent and are easy to care for.

Vitamin E was discovered in 1922, identified because it was essential for fertilized rat eggs to culminate in live births.

"Why does an embryo need vitamin E? We've been chasing that for a long time," said Traber, a leading authority on vitamin E who has been researching the micronutrient for three decades. "With this newest study we actually started taking pictures so we could visualize: Where is the brain? Where is the brain forming? How does vitamin E fit into this picture?"

In an embryo, a brain primordium and the neural tube appear early and will form the nervous system and "innervate" - supply with nerves - all organs and body structures. Without vitamin E, the zebrafish embryos showed neural tube defects and brain defects.

"They were kind of like folic acid-deficient neural tube defects, and now we have pictures to show the neural tube defects and brain defects and that vitamin E is right on the closing edges of the cells that are forming the brain," Traber said. 

In healthy organisms, neural crest cells drive the creation of facial bones and cartilage and innervate the body, building the peripheral nervous system.

"Acting as stem cells, the crest cells are important for the brain and spinal cord and also go on to be the cells of about 10 different organ systems including the heart and liver," Traber said. "By having those cells get into trouble with vitamin E deficiency, basically the entire embryo formation is dysregulated. It is no wonder we see embryo death with vitamin E deficiency."

Traber likens it to the children's game KerPlunk, in which kids take turns pulling out the straws that support several dozen marbles in a vertical tube. When the wrong straw is pulled out, everything collapses; vitamin E is the straw whose extraction brings down the house on embryo development, especially with the brain and nervous system.

"Now we're at the point where we're so close being able to say exactly what's wrong when there isn't enough vitamin E but at the same time we're very far away because we haven't found what are the genes that are changing," she said. "What we know is the vitamin E-deficient embryos lived to 24 hours and then started dying off. At six hours there was no difference, by 12 hours you see the differences but they weren't killing the animals, and at 24 hours there were dramatic changes that were about to cause the tipping point of total catastrophe."

Vitamin E, known scientifically as alpha-tocopherol, has many biologic roles and in human diets is most often provided by oils, such as olive oil. It is found in high levels in foods such as hazelnuts, sunflower seeds and avocados.

Vitamin E is a group of eight compounds - four tocopherols and four tocotrienols - distinguished by their chemical structure. Alpha-tocopherol is what vitamin E commonly refers to and is found in supplements and in foods associated with a European diet; gamma-tocopherol is the type of vitamin E most commonly found in a typical American diet.

"Plants make eight different forms of vitamin E, and you absorb them all, but the liver only puts alpha-tocopherol back into the bloodstream," said Traber. "All of the other forms are metabolized and excreted. I've been concerned about women and pregnancy because of reports that women with low vitamin E in their plasma have increased risk of miscarriage."

Joining Traber on the study were Brian Head of the Linus Pauling Institute, Jane La Du and Robyn Tanguay of the OSU College of Agricultural Sciences and Chrissa Kioussi of the OSU College of Pharmacy.

The Oregon Veterinary Diagnostic Lab supported the research with technical assistance, and the Ava Helen Pauling Endowment and the National Institute of Environmental Health Sciences of the National Institutes of Health contributed toward the study's funding.

 

Lactobacillus rhamnosus attenuates bone loss and maintains bone health 

All India Medical Institute (India), September 18, 2020

 

According to news reporting based on a preprint abstract, “Osteoporosis is a systemic-skeletal disorder characterized by enhanced fragility of bones leading to increased rates of fractures and morbidity in large number of populations. Probiotics are known to be involved in management of various-inflammatory diseases including osteoporosis.

“But no study till date had delineated the immunomodulatory potential of Lactobacillus rhamnosus (LR) in bone-health.

“In the present study, we examine the effect of probiotic-LR on bone-health in osteoporotic (Ovx) mice model.

“We observed that administration of LR attenuated bone-loss in Ovx mice. Both the cortical and trabecular bone-content of LR treated group was significantly higher than Ovx-group. Remarkably, the percentage of osteoclastogenic-CD4+Ror{gamma}t+Th17 cells at distinct immunological sites such as BM, spleen, LN and PP were significantly reduced, whereas the percentage of anti-osteoclastogenic-CD4+Foxp3+Tregs and CD8+Foxp3+Tregs were significantly enhanced in LR-treated group thereby resulting in inhibition of bone-loss. The immunomodulatory-role of LR was further supported by serum-cytokine data with a significant reduction in proinflammatory-cytokines (IL-6, IL-17 and TNF-) along with enhancement in anti-inflammatory-cytokines (IL-10, IFN-{gamma}) in LR treated-group. Altogether, the present study for the first time establishes the osteoprotective role of LR on bone-health, thus highlighting the potential of LR in the treatment and management of various bone related diseases including osteoporosis.”
