Researchers at NYU School of Medicine have developed a method to measure anatomical changes in the entorhinal cortex, a key memory center in the brain. This technique uses MRI scans and reveals that patients with very mild Alzheimer's disease show significant shrinkage in this area compared to healthy volunteers.
Researchers found a strong relationship between reading nutrition labels and eating less fat. People who read labels tend to consume 30% or less of their daily calories from fat, compared to 35% for non-label readers.
Klaus Toepfer warns of a growing global conflict over natural resources, particularly water, as the world's population is projected to increase dramatically. He advocates for monitoring drinking water reserves, cooperative agreements, and economic incentives for new technologies to promote water conservation.
A 10-year-old study found that early childhood anemia can lead to poor school performance and mild to moderate mental retardation. The research strengthens the need for effective identification and treatment of iron deficiency in early childhood.
Researchers mapped brain regions affected by cocaine and found that addiction is linked to the right side of the brain. The study used a powerful brain-imaging technique to map frontal-lobe regions associated with cocaine's effects in 20 cocaine addicts.
A large retrospective study found that poor dietary intake of animal protein in postmenopausal women is associated with an increased risk of hip fracture. In contrast, calcium and vitamin D intake had no significant association.
Scientists have developed a novel gene therapy system that uses a molecular rheostat to control the activity of therapeutic genes. This system allows for precise dosage control and can be achieved through oral administration of a simple pill.
A study by Westwood Squibb Center for Dermatology Research found that Medicare policies contradict medical practice for treating actinic keratoses, which can develop into squamous cell carcinoma. In most cases, doctors prefer to remove lesions immediately, but Medicare won't reimburse doctors who do so on the first visit.
A study published in the American Journal of Clinical Nutrition found that African American women who lost weight on reducing diets burned less resting energy expenditure than their white counterparts. This difference was significant and may contribute to the higher prevalence of obesity among Black women in the US.
A large Danish study found moderate wine consumption protects against coronary heart disease. Red wine's high antioxidant content is linked to a healthier diet, including more fruit, vegetables, and fish consumed by wine drinkers compared to beer or spirits consumers.
