A study of 15 professional welders found they developed typical clinical signs of Parkinson's disease 15 years earlier than the general population. Brain imaging scans revealed no significant difference in dopamine levels between the welders and control patients, suggesting a possible environmental link.
A study by Penn researchers found that a common gene delivery system for muscular dystrophy can trigger an immune response in mice unless paired with a muscle-specific promoter. The use of restricted promoters is crucial before expanding clinical trials.
Idun Pharmaceuticals recreates key apoptosis reaction to understand mechanism of programmed cell death. The company screens new drugs modulating apoptosis using the assay, aiming to treat cancers, heart attacks, and strokes.
A landmark survey shows that patients with major depression often feel their illness isn't under complete control and experience few quality-of-life improvements. The study highlights a significant communication gap between primary care physicians and patients, leading to inadequate treatment and side effect management.
A study by Raben et al. found that postobese women have different metabolic profiles than never obese women, with greater insulin sensitivity and more efficient triacylglycerol storage. This suggests that weight loss may not entirely eliminate the risks associated with obesity.
A study published in the American Journal of Clinical Nutrition found that energy-restricted diets had the most beneficial effects on serum lipids, lowering triglycerol concentrations and elevating HDL cholesterol. The authors suggest reevaluating current low-fat diet recommendations for individuals with excess body weight.
The Canadian Medical Association Journal has published new clinical practice guidelines for managing lymphedema related to breast cancer treatment. The guidelines include an updated patient version for women battling the condition. These updates aim to improve patient care and outcomes.
A new study by Cincinnati Children's Hospital Medical Center reveals that some children receive five times more radiation than necessary during CT scans. Researchers found that adjusting technical factors like tube current and pitch can significantly reduce exposure without sacrificing image quality.
A study found that the cholesterol-lowering drug pravastatin reduced stroke risk by 20% in patients with heart disease or high cholesterol. The medication also showed benefit when combined with aspirin and blood-pressure-lowering drugs, providing a new approach to preventing strokes.
Scientists have detected early indications of a lobster decline in the Gulf of Maine, with juvenile lobsters showing a 40% decrease in Penobscot Bay. The research team's approach to monitoring three stages of lobster life suggests widespread declines at least west of Penobscot Bay.
A study by Dr. Vivek Goel and colleagues found that women with early-stage breast cancer treated in specialized teaching hospitals had a higher 5-year survival rate than those treated in community hospitals. The results suggest that initial treatment at specialized centers may be advantageous for women with small tumors.
A study found that nutrient-dense food supplementation significantly lowered serum homocysteine and methylmalonic acid levels, indicating a reduction in cardiovascular risk. However, exercise had no effect on neuropsychological functioning or nutritional health in frail elderly subjects.
A new therapy effectively treats a disease similar to multiple sclerosis in monkeys by targeting T cells that cause the disease. The approach could soon be tested against MS and other autoimmune diseases in humans, offering potential for improved treatment options.
A new study found that puberty causes a general metabolic slowdown in both white and African American adolescents, with African Americans having greater lean mass in limbs but lower lean mass in the trunk. This difference may contribute to a lower resting energy expenditure (REE) in African Americans.
A new study found that women treated in teaching hospitals for initial breast cancer surgery had a five-year survival rate of 93%, compared to 89% for those treated in community hospitals. Comprehensive care approaches and multidisciplinary services may contribute to these differences.
