An analysis of previous studies suggests that for patients with a suspected blood clot in a deep vein of a leg, withholding anticoagulation therapy after a negative whole-leg compression ultrasound is associated with a low risk of developing a blood clot during the subsequent 3 months, suggesting that multiple ultrasounds may not be necessary for some low-risk patients, according to an article in the February 3 issue of JAMA.

Being diagnosed with prostate cancer may increase a man's risk of suicide or cardiovascular death, especially right after diagnosis, according to a new study published online February 2 in the Journal of the National Cancer Institute.
GAINESVILLE, Fla. — A 60-million-year-old relative of crocodiles described this week by University of Florida researchers in the Journal of Vertebrate Paleontology was likely a food source for Titanoboa, the largest snake the world has ever known.
RICHMOND, Va. (Feb. 2, 2010) – An international team of researchers has identified a new theoretical approach that may one day make the synthesis of hydrogen fuel storage materials less complicated and improve the thermodynamics and reversibility of the system.
Pyrethroids, among the most widely-used home pesticides, are winding up in California rivers at levels toxic to some stream-dwellers, possibly endangering the food supply of fish and other aquatic animals, according to a new study by researchers at the University of California, Berkeley, and Southern Illinois University (SIU).
The traditional practice of restricting food and fluids during labour does not provide any benefits, finds a new review co-authored by a Queen's University Associate Professor.
"Based on our review, there is no convincing and current evidence to support restriction of fluids, and perhaps food, for women during labour. Women should be able to choose for themselves," says Dr. Joan Tranmer of the Queen's School of Nursing.
WASHINGTON, DC (February 2, 2010) – Pamphlets detailing the warning signs associated with heart disease may soon end up in an unexpected location: your child's pediatrician's office. According to new research from the Centers for Disease Control and Prevention (CDC), one in five American teens has at least one risk factor for developing heart disease in adulthood.
LOS ANGELES (Feb. 1, 2010) – Fat tissue in women with Polycystic Ovary Syndrome produces an inadequate amount of the hormone that regulates how fats and glucose are processed, promoting increased insulin resistance and inflammation, glucose intolerance, and greater risk of diabetes and heart disease, according to a study conducted at the Center for Androgen-Related Research and Discovery at Cedars-Sinai Medical Center.
Agricultural Research Service (ARS) scientists have developed an efficient and cost-effective method to speed up the breeding of scab-resistant barley cultivars, thus improving crop quality for small-grain breeders in the Northern Plains.
Shiaoman Chao, a molecular geneticist at the ARS Cereal Crops Research Unit in Fargo, N.D., collaborated with scientists from North Dakota State University and the University of Minnesota in the study.
CHICAGO -- Gail Donnelly's classmates nicknamed her "Knobby" because she was so skinny all her bones seemed to poke out from under her skin. But when Donnelly turned 27, that once knobby frame disappeared under mysteriously ballooning weight. Her diet hadn't changed, she was still walking several miles a day, but she gained 50 pounds in just six months.
DALLAS – Feb. 2, 2010 – Prostate cancer cells are more likely to spread to other parts of the body if a specific gene quits functioning normally, according to new data from researchers at UT Southwestern Medical Center.
A new weight-loss supplement tested by the University of Oklahoma Health and Exercise Science Department has the potential to burn as many calories as a 20-minute walk, according to Joel T. Cramer, assistant professor of exercise physiology.
By considering molecular-level events on a broader scale, researchers now have a clearer, if more complicated, picture of how one class of immune cells goes wrong when loaded with cholesterol. The findings reported in the February 3rd issue of Cell Metabolism, a Cell Press publication, show that, when it comes to the development of atherosclerosis and heart disease, it's not about any one bad actor—it's about a network gone awry.
Cleft palate has been linked to dozens of genes. During their investigation of one of these genes, researchers at Washington University School of Medicine in St. Louis were surprised to find that cleft palate occurs both when the gene is more active and when it is less active than normal.
Exposure to severe stress early in life increases the risk of alcohol and drug addiction. Yet surprisingly, some adults sexually abused as children — and therefore at high risk for alcohol problems — carry gene variants that protect them from heavy drinking and its effects, according to researchers at Washington University School of Medicine in St. Louis.
