January 13 2017. A study reported on December 23, 2016 in Biology Open suggests a benefit for niacin (vitamin B3) in the treatment of early stage Parkinson’s disease. The research involved fruit flies with a mutation which results in a condition similar to human Parkinson’s disease. L. Miguel Martins and colleagues at the University of Leicester fed the flies a diet supplemented with niacin, which is a precursor to nicotinamide adenine dinucleotide (NAD), a coenzyme needed for the generation of energy in the cells’ mitochondria. NAD also helps protect neurons from degeneration.
January 18 2017. An article published on January 17, 2017 in Nature Communications reports the conclusion of researchers at the University of Wisconsin-Madison and the National Institute on Aging (NIA) that calorie restriction among older rhesus monkeys results in longer life. The research, which attempted to resolve conflicting findings concerning the effect of calorie restriction on life span, is the first collaboration between the two competing research teams.
January 20 2017. Inflammaging, defined as chronic, systemic low-grade inflammation that occurs with aging in the absence of overt infection, has been hypothesized as a mechanism of age-associated disease and premature mortality. A cause of inflammaging has been attributed to lifetime exposure to a variety of antigens via the intestine.
January 23 2017. A study reported on January 11, 2017 in The Aging Male found improvements in testosterone levels, erectile function and indicators of metabolic syndrome among men who received vitamin D over a one year period. “Given that patients with low total testosterone often have low vitamin D levels, collectively, research suggests a relationship between low vitamin D and low total testosterone, and increased risk of type 2 diabetes mellitus,” note Ondor Canguven of Hamad General Hospital in Doha, Qatar and colleagues.
January 25 2017. An article appearing on January 11, 2017 in the American Journal of Clinical Nutrition provides more evidence for a higher vitamin E requirement among people with metabolic syndrome, a cluster of factors that increase the risk of diabetes and cardiovascular disease. The research builds on findings reported in the November 2015 issue of the journal, in which Richard S. Bruno and colleagues had determined that vitamin E was less bioavailable in subjects with metabolic syndrome than healthy subjects.
January 27 2017. On January 25, 2017, The Laryngoscopereported the discovery of researchers at Thomas Jefferson University of mechanisms associated with the drug metformin against cancer of the head and neck. "This study is the first step in showing how metformin acts on head and neck tumors, and we are excited that it could eventually offer patients a method of improving their outcomes with few side effects," announced senior author Ubaldo Martinez-Outschoorn.
testosteroneJanuary 30 2017. A clinical trial reported in the January 2017 issue of Pain Physician uncovered a benefit for supplementing with vitamin D among individuals with chronic lower back pain. The condition is the second most common pain complaint after headache and can be notoriously resistant to treatment.
