Gene links to anorexia identified: Largest genetic study of the eating disorder detects common and rare variants (November 20, 2010) -- Scientists have identified both common and rare gene variants associated with the eating disorder anorexia nervosa. In the largest genetic study of this psychiatric disorder, the researchers found intriguing clues to genes they are subjecting to further investigation, including genes active in neuronal signaling and in shaping interconnections among brain cells. ... > full story
Personalized medicine: Tumor analysis reveals new opportunities for existing cancer drugs (November 20, 2010) -- Targeted cancer therapies such as trastuzumab (Herceptin), gefitinib (Iressa) and erlotinib (Tarceva) could be used to treat a wider range of cancers than previously thought, according to new research. ... > full story
Designing more effective anti-HIV antibodies (November 20, 2010) -- Although people infected with HIV produce many antibodies against the protein encapsulating the virus, most of these antibodies are strangely ineffective at fighting the disease. A new study suggests why some of the most common of these antibodies don't work: they target the protein in a form it takes after the virus has already invaded the cell, when it's too late, report researchers. ... > full story
Cholesterol-lowering statins boost bacteria-killing cells (November 20, 2010) -- Widely prescribed for their cholesterol-lowering properties, recent clinical research indicates that statins can produce a second, significant health benefit: lowering the risk of severe bacterial infections such as pneumonia and sepsis. Scientists now describe how statins activate the bacterial killing properties of white blood cells. ... > full story
Reports claiming amyotrophic lateral sclerosis caused by head trauma lacks scientific validation, review finds (November 20, 2010) -- A recent study suggesting that amyotrophic lateral sclerosis (ALS) may be attributed to "repetitive head trauma experienced in collision sports" lacks scientific epidemiological evidence to support this claim. In a review of the 12-patient study, several experts specializing in motor neuron diseases challenge the findings as entirely pathological and without clinical merit. ... > full story
Graphic images influence intentions to quit smoking (November 20, 2010) -- Marketing researchers surveyed more than 500 U.S. and Canadian smokers and found that the highly graphic images of the negative consequences of smoking have the greatest impact on smokers' intentions to quit. The most graphic images, such as those showing severe mouth diseases, including disfigured, blackened and cancerous tissue, evoked fear about the consequences of smoking and thus influenced consumer intentions to quit. ... > full story
New target identified for stopping tumors developing their own blood supply (November 20, 2010) -- Researchers have found that a newly developed drug, which is aimed at a particular receptor involved in the development of blood vessels that sustain tumor growth, is active in patients with advanced cancers and, in some cases, has halted the progress of the disease. The drug targets a different molecular pathway to other anti-angiogenesis drugs and may provide a new option to treat cancer. ... > full story
Combination therapy improves survival time for patients with advanced liver cancer (November 20, 2010) -- Treatment of inoperable advanced liver cancer with the agent doxorubicin (routinely used to treat this condition) in addition to the agent sorafenib resulted in greater overall survival and progression-free survival, compared to patients who received treatment with doxorubicin alone, according to a new study. ... > full story
New approach finds success in teaching youth with autism (November 20, 2010) -- Researchers are developing an effective social competence curriculum to help autistic children. ... > full story
First synthetic activator of two critical proteins identified: New approach to treat numerous metabolic disorders? (November 19, 2010) -- Scientists have identified a novel synthetic activator of a pair of proteins that belong to a protein family playing key roles in human metabolism and immune function. The discovery could provide new and potentially more effective therapeutic approaches to diseases ranging from diabetes to osteoporosis. ... > full story
Pomegranate juice reduces damage to tissues, inflammation and infections, study suggests (November 19, 2010) -- Studies in recent years have claimed multiple health benefits of pomegranate juice, including that it is a good source of antioxidants and lowers both cholesterol and blood pressure, especially in diabetic and hypertensive patients. A preliminary study now suggests that it can ward off a number of complications in kidney disease patients on dialysis, according to new study. ... > full story
First successful salivary stone removal with robotics (November 19, 2010) -- Doctors report the first use of a surgical robot guided by a miniature salivary endoscope to remove a 20mm salivary stone and repair the salivary duct of a patient. Giant stones have traditionally required complete removal of the salivary gland. This technique not only saves the salivary gland, but reduces blood loss, scarring, and hospital stay. ... > full story
