Study of menopausal women finds no benefit from hormone therapy and antioxidant vitamins
... heart attack and death and angiographic change, a predictor of future coronary events. By this measure, women receiving active hormone therapy showed more progression of their coronary disease than women receiving placebo. Women receiving active vitamins had a similar degree of angiographic change as women r...NIH study shows MRI provides faster, more accurate way to diagnose heart attacks
...pecific than abnormal EKG. "MRI was the strongest predictor of acute coronary syndrome - for both heart attacks and unstable angina," said Dr. Andrew Arai, principal investigator of the study, who leads the cardiovascular imaging section of the NHLBI Laboratory of Cardiac Energetics. "MRI allows us to look a...Family history doesnt predict colon cancer genes, behavior
.... Despite these findings, family history is a poor predictor of whether an individual has a colon cancer-related gene or diet or medication risk factors, Keku and colleagues conclude.There was no significant difference in how often individuals with a family history participated in colon cancer screenings compa...Leatherback sea turtles careening towards extinction
...or bottom features? "Unfortunately the single best predictor is swordfish catch the more swordfish caught, the higher the rate of leatherback bycatch," says Crowder. To help remedy this problem, U.S. longline fisheries already have been restricted or closed, but this will not adequately protect leatherbacks. ...A new way to compare human and other primate genomes
... high blood levels of apo(a) are an important risk predictor for cardiovascular disease. The desire to study apo(a) is the reason Rubin and his research group began the development of their phylogenetic shadowing technique. "We could not study apo(a) by comparing human DNA sequences to the sequences of evoluti...As harmful as osteoporosis but less well known - New research better explains sarcopenia

... C35 may eventually become a target of therapy and predictor of prognosis in breast cancer," said Deepak M. Sahasrabudhe, M.D., director of the Hematology-Oncology Fellowship Program and Professor of Medicine and Oncology at the University of Rochester School of Medicine and Dentistry, New York. The study, a...Physical activity in the elderly ruled in part by genetics
...city (maximal ability to perform work) is a strong predictor for the risk of death in men, both healthy and with cardiovascular disease. These findings, adding to the understanding that biological factors have a role in age-related physical activity decline, will make a significant contribution to the effort ...Location of ulcerations in diabetic patients may be explained by blood flow

Ultimately, this research will lead to treatments, which propose to alter the repetitive pressures experienced by the plantar surface of the foot to improve skin vascular compensatory mechanisms....Carnegie Mellon University research story ideas on DNA
...d into a protein, so it can be a wildly inaccurate predictor of a protein's presence. Furthermore, one mRNA can undergo editing (splicing) to produce many different proteins whose presence wouldn't be captured by simply detecting the mRNA. To circumvent these issues, Mellon faculty have created groundbreakin...Tufts University biologists unveil more mysteries of fireflies flash
...hat the length of a male firefly's flash is a good predictor of the nuptial gift he's capable of delivering. "Because Photinus fireflies don't eat once they become adults, male nuptial gifts provide a key source of nutrition for a female and her eggs," says Cratsley. Lewis plans to continue her firefly rese...Estrogen patch compared to pill minimizes cardiovascular risk factor in postmenopausal women

...unt of lipid inside the muscle cell is a very good predictor of insulin resistance," said Shulman. Studies of the fat tissue in the elderly subjects showed that the fat cells were not releasing the extra fat that was accumulating in muscle. Thus, reasoned the researchers, the fatty molecules in the muscle cel...Biodiversity's response to ecosystem productivity depends on historical plant, animal relationships

Such a predictor could help patients and families, with their physicians, decide the most appropriate action, which could range from more aggressive therapy at the outset to avoiding therapies that are more likely to hurt quality of life for the patient than to exten...Genetic differences revealed by SNPS play a role in risk, prevention and outcome for cancer
