Researchers from Memorial Sloan-Kettering Cancer Center found that hospitals with high volume of surgery for selected procedures had substantially lower surgical mortality rate. Mortality rates were 40-80% lower in these hospitals compared to those with limited experience.
Researchers have discovered a novel function of the Survival Motor Neuron (SMN) protein essential for mRNA production in all cells. This finding links SMN deficiency to spinal muscular atrophy, a leading genetic cause of infant death, and paves the way for potential therapeutic interventions.
Researchers have found that decreasing pan evaporation does not necessarily mean less evaporation in surrounding landscapes. By considering regional land-surface moisture, environmental engineers explain how evaporation figures can drop due to saturated terrain, resolving the paradox.
Scientists at the University of Chicago have discovered a substance that can induce hair follicle formation in mature skin cells, offering new possibilities for treating premature baldness. By manipulating the beta-catenin molecule, researchers were able to create new hair follicles from adult skin cells, paving the way for potential t...
Researchers at Duke University have identified 31 genes that react to cadmium exposure, including 22 previously unknown genes. These findings offer new insights into the toxic effects of cadmium and potential biomarkers for monitoring contamination.
Researchers at UT Southwestern Medical Center have identified a mutation that prevents sperm maturation in mice, which could lead to treatments for male sterility and development of new male contraceptives. The morc gene is expressed only in males during the earliest stages of sperm production.
Researchers found that rats fed high amounts of fructose for a year showed age-related alterations in their skin and bone collagen. Fructose consumption may decrease glucose tolerance, increase insulin resistance, and speed up glycation, contributing to aging processes.
Researchers identified five common 'warning signals' of depression: less enjoyment from activities, self-disappointment, hopelessness, irritability, and difficulty sleeping. These symptoms were reported by at least 90% of the sample, and women reported self-disappointment with the greatest frequency.
Researchers at UT Southwestern Medical Center discovered that vitamin E can prevent the early stages of plaque formation by inhibiting the attachment of white blood cells to endothelial cells. Vitamin E's antioxidant properties help reduce the risk of atherosclerosis, or hardening of the arteries.
The new detection system, developed by Dr. Gregg Henderson and his team, samples the air in building walls to analyze for termites' unique gases. Early detection could prevent significant damage, saving homeowners millions annually.
A Norwegian study found that depressed men with congestive heart failure are more likely to perceive themselves as physically limited, even if their physicians rate them highly. In contrast, women with the condition tend to have a more realistic assessment of their abilities.
