A new study published in the Journal of the American Dietetic Association found that many middle-aged and older Americans are not getting adequate nutrition. Supplement use was associated with meeting recommended dietary intakes for calcium, magnesium, and vitamin C, but potassium intake remained low regardless of supplement use.
A study reveals that fire-related deaths are a major public-health problem in India, with over 163,000 deaths in 2001, mostly among young women. The authors estimate that these deaths are six times higher than reported by the police and suggest common causes including kitchen accidents, self-immolation, and domestic violence.
A study suggests that childhood sleep problems persisting through adolescence can affect cognitive abilities, particularly executive functioning. Sleep problems during late childhood and early adolescence, such as being overtired or sleeping more than others, were found to be strong predictors of later executive control.
A new study suggests that drinking alcohol in early adulthood may increase the risk of reflux esophagitis (RE) and Barrett's esophagus (BE), while wine consumption may reduce this risk. Higher education levels are also inversely associated with BE risk, suggesting socioeconomic status plays a role in the development of these conditions.
Dr. Nagy's method uses a novel wrapping procedure to deliver specific genes, overcoming major hurdles for personalized stem cell therapies. The breakthrough accelerates stem cell technology and provides a road map for new clinical approaches to regenerative medicine.
Scientists have discovered a compound called zymosan that can respond to two different receptors in dendritic cells, sending both stimulatory and calming messages. This finding could guide the development of vaccines against infectious agents and potentially boost the immune system's ability to fight chronic infections.
Researchers have developed a potent drug against melanoma by combining compounds from green vegetables with selenium. The new compound, isoselenocyanate, targets the Akt3 protein and reduces tumor growth by 50-60%, showing potential for low-toxicity treatment.
Research published in Clinical Gastroenterology and Hepatology found that patients with upper GI bleeding admitted on weekends had a 22% higher mortality rate and were less likely to undergo early endoscopy. Patients with peptic ulcer-related UGIB also faced increased mortality, hospital charges, and length of stay.
A new study reveals that children with attention deficit/hyperactivity disorder (ADHD) have a shorter total sleep time and reduced rapid eye movement (REM) sleep compared to healthy controls. This intrinsic sleep problem may contribute to the symptoms of ADHD.
Researchers have long focused on Toxin A, but a new study reveals Toxin B is the real culprit behind C-diff's deadly effects. The discovery has significant implications for treatment and prevention strategies.
Duke researchers found that a blood-derived lymph node dendritic cell type plays a key role in developing acute T-cell responses. This discovery challenges traditional views on dendritic cell function and has implications for vaccine science and autoimmune disease therapy development.
A school-based sleep intervention improved adolescents' sleep problems, producing a high retention rate of 83% and increasing students' knowledge of sleep-related issues. However, the positive effect disappeared at the six-week follow-up.
