CHICAGO – Patients with certain genes or specific factors related to use of the anti-clotting drug clopidogrel are more likely to experience a blood clot within a coronary stent shortly after placement, according to a study in the October 26 issue of JAMA.

CHICAGO – Among men who were current or former heavy smokers, undergoing lung cancer screening with computed tomography (CT) scanning identified a substantial proportion who had chronic obstructive pulmonary disease (COPD), suggesting that this method may be helpful as an additional tool in detecting COPD, according to a study in the October 26 issue of JAMA.
Changes in North American ecosystems over the past 150 years have caused coyotes to move from their native habitats in the plains and southwestern deserts of North America to habitats throughout the United States.
It's a moment burned into the minds of Red Sox and Yankee fans alike – sitting inches away from the television, fists clenched, tightness in the chest and the unbearable urge to look away…
More patients with ovarian carcinoma carry cancer-predisposing mutations, and in more genes, than previously thought.
A rapid experimental method for screening genomes has located mutations in 12 genes for inherited cancers of the ovary, fallopian tubes and peritoneum (the thin tissue lining the lower abdomen).
PITTSBURGH, Oct. 25 – A panel of blood proteins can predict which patients with the progressive lung disease idiopathic pulmonary fibrosis (IPF) are likely to live at least five years or to die within two years, say researchers at the University of Pittsburgh School of Medicine and Centocor R&D. The findings, published online last week in the American Journal of Respiratory and Critical Care Medicine, could help doctors determine those patients in imminent need of a lung transplant and those who can wait a while longer.
MOUNTAIN VIEW, CA – (October 25, 2011) – 23andMe, Inc., a leading personal genetics company, has announced the first-time discovery of the potentially protective nature of the gene serum/glucocorticoid regulated kinase 1 (SGK1) which appears to be protective against a high-risk leucine-rich repeat kinase 2 (LRRK2) mutation for Parkinson's disease (PD).
RICHLAND, Wash. -- Early detection of breast cancer saves thousands of lives each year. But screening for breast cancer also produces false alarms, which can cause undue stress and costly medical bills. Now, a recent study using patient blood reveals a possible way to reduce the number of false alarms that arise during early screening. Researchers found a panel of proteins shed by breast cancer that are easily detected and can distinguish between real cancer and benign lumps.
Any way you slice it, bread that contains critical nutrients could help combat severe malnutrition in impoverished regions. That is the goal of a group of Johns Hopkins University undergraduate students who are using synthetic biology to enhance common yeast so that it yields beta carotene, the orange substance that gives carrots their color. When it's eaten, beta-carotene turns into vitamin A.
Alexandria, Va., USA - In a report on a preclinical investigation titled "Flagellin Enhances Saliva IgA Response and Protection of Anti-caries DNA Vaccine," lead author Wei Shi, Wuhan Institute of Virology, Chinese Academy of Sciences, and his team of researchers demonstrate that anti-caries DNA vaccines, including pGJA-P/VAX, are promising for preventing dental caries. However, challenges remain because of the low immunogenicity of DNA vaccines.
A low-fat diet with fish oil supplements eaten for four to six weeks prior to prostate removal slowed down the growth of prostate cancer cells -- the number of rapidly dividing cells -- in human prostate cancer tissue compared to a traditional, high-fat Western diet.
Tampa, FL -- Researchers at the University of South Florida (USF) College of Public College Health have shown for the first time in a rodent model that the earliest form of malaria parasites can lay dormant in red blood cells and "wake up," or recover, following treatment with the antimalarial drug artesunate.
For years, scientists believed the vast phenotypic differences between humans and chimpanzees would be easily explained – the two species must have significantly different genetic makeups. However, when their genomes were later sequenced, researchers were surprised to learn that the DNA sequences of human and chimpanzee genes are nearly identical. What then is responsible for the many morphological and behavioral differences between the two species?
Researchers in the Virginia-Maryland Regional College of Veterinary Medicine at Virginia Tech have identified the first strains of hepatitis E virus from farmed rabbits in the United States. It is unknown whether the virus can spread from rabbits to humans.
PHILADELPHIA - Obesity and insulin resistance are almost inevitably associated with increases in lipid accumulation in the liver, a serious disease that can deteriorate to hepatitis and liver failure. A real paradox in understanding insulin resistance is figuring out why insulin-resistant livers make more fat. Insulin resistance occurs when the body does a poor job of lowering blood sugars.
