Cholesterol byproduct blocks heart health benefits of estrogen
New findings by UT Southwestern Medical Center researchers show that a byproduct of cholesterol metabolism interferes with the beneficial effects estrogen has on the cardiovascular system, providing a better understanding of the interplay between cholesterol and estrogen in heart disease.[see more details in eurekalert.com]
Gene determines whether male body odor smells pleasant
Up to one-third of adult humans cannot perceive an odor in a component of male body odor that induces physiological responses in both men and women. To those who do, androstenone either takes on a pleasant sweet odor or a repulsive urine-like one. New research from Rockefeller University and Duke University traces this variability to mutations in a single odorant receptor gene, a finding that raises questions of how people detect other people�s body odor.[see more details in eurekalert.com]
Good earth: Brown chemists show origin of soil-scented geosmin
Brown University chemists have figured out precisely how the warm, slightly metallic scent of freshly turned soil is made. In Nature Chemical Biology, the team describes how geosmin, the organic compound responsible for the scent, is produced by an unusual bifunctional enzyme.[see more details in eurekalert.com]
M.D. Anderson-led team reports possible key to autoimmune disease
A self DNA-peptide complex triggers an immune response like that caused by a virus or other invading microbe. Researchers believe this response is both a likely key driver of autoimmune disease and an integral part of an early warning system that flags tissue damage to launch a protective inflammatory response to injury.[see more details in eurekalert.com]
The importance of gene regulation for common human disease
A new study published in Nature Genetics on Sunday Sept. 16, 2007, shows that common, complex diseases are more likely to be due to genetic variation in regions that control activity of genes, rather than in the regions that specify the protein code. This surprising result comes from a study at the Wellcome Trust Sanger Institute of the activity of almost 14,000 genes in 270 DNA samples collected for the HapMap Project.[see more details in eurekalert.com]

More Sick Leave Given To Men By Male GPs Compared With Female Counterparts
Male patients are given more certified sick leave by male doctors compared with the amount of sick notes given to females by female doctors, a new study has revealed. Mild mental disorders (MMDs) such as depression and anxiety were the commonest cause of complaint by women, followed by musculoskeletal problems for which males sought a higher proportion of medical attention. The research revealed however, that male patients were granted a longer amount of sick leave for MMDs compared with female patients, by doctors of both genders groups.[see more details in sciencedaily.com]
