A NASA review highlights known and potential gender differences in physiological responses to spaceflight, including cardiovascular and exercise physiology, barophysiology, and pharmacotherapeutics. The review also addresses reproductive issues such as menstrual function and endometriosis in space.
Researchers at the University of Pittsburgh Medical Center have successfully implanted LBS-neurons into patients with chronic stroke, showing a greater than 10% increase in metabolic activity in damaged areas. The surrounding area showed maintained or improved function, suggesting integration of the new neurons.
Jan L. Breslow and David A. Ness received the 2001 American Heart Association Gold Heart Award for their leadership in research, administration, and volunteer work. The award recognizes their significant contributions to advancing heart health through their work with the association.
Researchers have discovered that synthetic superoxide dismutase and catalase can extend the lifespan of C. elegans nematode worms by approximately 50%. These catalytic drugs convert oxygen radicals into water, reducing oxidative stress and protecting mitochondrial function.
Researchers at Boston University developed a computer model to analyze how molecules move through super-cooled water, providing insights into life's survival at sub-zero temperatures. By understanding the 'energy landscape' of super-cooled water, scientists can predict how molecules diffuse and carry nutrients to cells.
Researchers have found a way to convert oil to methane gas using specialized microorganisms living beneath the earth's surface. This breakthrough could lead to safer oil exploration and more efficient extraction methods.
Aging affects dopamine levels, leading to decreased glucose metabolism and brain activity in regions related to cognition. This finding may help develop interventions for age-related cognitive decline.
A new study found that walking rapidly for 45 minutes, three days a week, can significantly improve mental-processing abilities in adults over 60. The exercise triggered faster reaction times and heightened the ability to ignore distractions on computer tasks.
The editorial reviews the effects of moderate alcohol consumption on stimulating appetite and food intake. It highlights the need for long-term studies to understand its impact on body weight.
The new volume of the American Geophysical Union's Antarctic Research Series delves into the complex ecosystems found in Antarctic sea ice. Researchers explore various habitats, including algal biomass, nitrogen metabolism, and numerical ecosystem modeling studies, providing insights into the biodiversity of this unique environment.
Researchers found that extrusion-processed wheat bran in cereals can reduce the number of aberrant crypt cells in laboratory rats by up to 40%, compared to raw wheat bran and flaked cereals. The study suggests that processing wheat bran improves its health-promoting properties, making it a potential tool in reducing colon cancer risk.
The first investigation of estrogen metabolism in prostate cancer will determine if differences exist between healthy men and those with the disease. The study aims to find potential new strategies to prevent this important disease.
Researchers at UPMC Health System found abnormally high metabolism in the amygdala, a small area of the brain, may cause many symptoms of depression. The study's findings may lead to more effective antidepressant and mood stabilizing treatments for nearly 19 million people affected by these disorders.
According to Bruce Rittmann, microbes can break down a wide variety of pollutants, including PCBs and chlorinated solvents, through processes such as in situ bioremediation. In these processes, microbes are fed oxygen and nutrients to stimulate their growth and degradation of contaminants.
