Researchers call for early diagnosis of flesh-eating infections Posted: 17 Sep 2012 09:42 AM PDT Researchers stress that orthopedists should have a high index of suspicion for necrotizing fasciitis, or flesh-eating bacterial infection, in every patient with pain or other symptoms that are out of proportion to the initial diagnosis. |
Toxic protein build-up in blood shines light on fatal brain disease Posted: 17 Sep 2012 09:39 AM PDT A new light-based technique for measuring levels of the toxic protein that causes Huntington's disease (HD) has been used to demonstrate that the protein builds up gradually in blood cells. The findings shed light on how the protein causes damage in the brain, and could be useful for monitoring the progression of HD, or testing new drugs aimed at suppressing production of the harmful protein. |
Adequate sleep helps weight loss Posted: 17 Sep 2012 09:39 AM PDT Adequate sleep is an important part of a weight loss plan and should be added to the recommended mix of diet and exercise, states an expert. |
Cervical cancer and pre-cancer cervical growths require single HPV protein Posted: 17 Sep 2012 09:38 AM PDT Human papillomavirus (HPV) has long been implicated in cervical cancer, but details of how it happens have remained a mystery. Now researchers have found that a single HPV protein is required for cervical cancer and even pre-cancer growths in the cervix to survive. |
Mechanism that leads to diabetes, blindness, identified Posted: 17 Sep 2012 09:38 AM PDT The rare disorder Wolfram syndrome is caused by mutations in a single gene, but its effects on the body are far reaching. Now, researchers report that they have identified a mechanism that affects both insulin-secreting cells and neurons. The finding will aid in the understanding of Wolfram syndrome and also may be important in the treatment of milder forms of diabetes and other disorders. |
Eating well during pregnancy reduces baby's obesity risk regardless of mom's size Posted: 17 Sep 2012 09:38 AM PDT If you are overweight and pregnant, your baby isn't destined to become obese, according to a research report. The report shows that modifying fat intake during pregnancy to a moderate level benefits the child regardless of the mother's size. Specifically, they found that the protein "SIRT1" rewrites a developing fetus' histone code, which affects his or her "epigenetic likelihood" of being overweight throughout his or her lifetime. |
Scientists bid to develop anthrax vaccine to counteract world bioterrorism threat Posted: 17 Sep 2012 09:34 AM PDT A team of scientists is leading new research to develop a vaccine against anthrax to help counteract the threat of bioterrorism. |
At the right place at the right time: New insights into muscle stem cells Posted: 17 Sep 2012 09:31 AM PDT Muscles have a pool of stem cells in special niches which provides a source for muscle growth and for the regeneration of injured muscles. Researchers have elucidated how these stem cells colonize these niches. They also show that the stem cells weaken when, due to a mutation, they locate outside of the muscle fibers. |
Scientists reveal how natural antibiotic kills tuberculosis bacterium Posted: 17 Sep 2012 09:31 AM PDT A natural product secreted by a soil bacterium shows promise as a new drug to treat tuberculosis report scientists.
