Researchers found that obese subjects showed an attenuated response to simulated sunlight, with serum vitamin D concentrations less than half those of lean individuals. Oral administration of vitamin D2 was more effective in raising serum concentrations, suggesting that obese individuals sequester vitamin D in body fat.
A new study shows that drug treatment interruptions can boost HIV-specific immune responses in chronically infected patients, with one patient controlling his viral infection without drugs for at least four months. This approach, known as structured treatment interruption, may provide a sustainable alternative to current treatments.
Researchers found that 19 out of 47 people with mild cognitive impairment who had difficulty identifying smells went on to develop Alzheimer's disease. The study suggests that the inability to recognize smells, combined with a lack of awareness about impaired olfactory senses, may be used as a predictor of impending Alzheimer's disease.
A six-month study found that isoflavone-rich soy protein isolate attenuated bone loss in the lumbar spine of perimenopausal women. The treatment group showed a significant reduction in bone mineral density and content compared to the control group. This suggests that soy may be a useful adjunct therapy for preventing osteoporosis in wo...
Adolescents raised on a strict macrobiotic diet during infancy and early childhood show signs of impaired cognitive function, including lower intelligence and spatial ability scores. A study found an association between vitamin B12 status and cognitive abilities, highlighting the potential risks of avoiding animal products.
The American Geophysical Union Fall 2000 meeting will take place at the Moscone Convention Center in San Francisco from December 15 to 19. Press registrants can access scientific sessions, the Press Room, and Briefing Room with a valid badge.
A study by Penn State researchers found that consuming larger portions of puffed-up food servings can reduce hunger and lead to a lower calorie intake. The study suggested using whipped foods like low-fat frozen desserts or air-popped popcorn as alternatives to manage weight.
Researchers at INEEL develop systems model to accurately assess greenhouse gas emissions from energy use. The model considers various factors, including energy efficiency and facility operations.
Research by Penn State and University of Nebraska found that moderate aggression is associated with a stronger immune system, particularly among CD4 cells. Men who reported engaging in occasional fights or aggressive acts had higher levels of lymphocytes, indicating a more rapid and intense response to pathogens.
Baltimore researchers will develop a new type of measles vaccine protecting infants younger than 9 months old, reducing global suffering and death rate from measles. A DNA vaccine approach using genetic material of the virus will be tested in humans to determine its effectiveness.
Researchers found that aerosol cyclosporine significantly reduced P-gp activity in lung transplant patients' immune cells, increasing effective drug absorption. The study aims to improve immunosuppressant therapy efficiency and reduce side effects.
A study published in the American Journal of Clinical Nutrition found that walking and weight loss reduced midthigh fat and improved glucose metabolism in older obese women. The intervention resulted in significant decreases in body weight, waist circumference, and cholesterol levels, as well as improvements in aerobic capacity.
A new process for making beta-lactam compounds could facilitate the creation of new antibacterial drugs, overcoming cost and chirality challenges. The process uses quinine as a catalyst to produce large batches of beta-lactams with desirable properties.
A large study of 191 nuns found no correlation between phosphorus and protein intake and calcium absorption. The researchers suggested that high protein diets may actually contribute to a negative calcium balance due to increased urinary calcium loss.
