A recent survey of over 43,000 US adults found that middle-aged adults are at a higher risk of developing depression, with the highest lifetime risk among those aged 45-64. The study also revealed significant correlations between depression and substance use disorders, anxiety, and personality disorders.
The Harvard Center for Risk Analysis examines the health effects of fish consumption, finding that moderate intake reduces stroke risk by 17% and coronary heart disease mortality by 3.9%. However, high mercury exposure may harm cognitive development.
Eating one fish meal per week provides significant nutritional benefit, but decreasing fish consumption can lead to lost omega-3 fatty acids and increased risks of coronary heart disease and stroke. The study suggests that the government advisories may be doing more harm than good by limiting fish intake.
A team of researchers has isolated a new defensin, plectasin, from fungi that is highly effective against drug-resistant bacteria. Plectasin targets specific strains of Streptococcus pneumoniae and Streptococcus pyogenes, including those resistant to conventional antibiotics.
A new study finds that cigarette smoking exacerbates brain atrophy in alcoholics, particularly in regions such as the parietal and temporal lobes. The researchers discovered a direct relationship between brain volume and cognitive function among non-smoking alcoholics, but no similar link was found among smokers.
A study by USF researchers found that green tea's epigallocatechin-3-gallate (EGCG) decreases production of the Alzheimer's-related protein beta-amyloid, leading to a 54% reduction in brain-clogging plaques. EGCG may be effective in preventing and treating Alzheimer's disease through dietary supplementation.
