Researchers find genetic proof on how osteoarthritis destroys cartilage

A team of orthopaedic researchers has found definitive, genetic proof of how the most common form of arthritis destroys joint cartilage in nearly 21 million aging Americans, according to a study published online Sept. 2 in the Journal of Bone and Mineral Research. The findings serve as an important foundation for the design of new treatments for osteoarthritis (OA), researchers said.

Discovery of novel candidate gene for inflammatory bowel diseases

A study of Crohn's disease and ulcerative colitis in children has identified a gene that influences whether children get these diseases early in life, and points to a potential new target for treatment.

Vitamin B deficiency may cause vascular cognitive impairment

A deficiency of B-vitamins may cause vascular cognitive impairment, according to a new study. Researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University used an experimental model to examine the metabolic, cognitive, and microvascular effects of dietary B-vitamin deficiency.

Hopkins researchers piece together gene "network" linked to schizophrenia

Reporting this week in the Archives of General Psychiatry, researchers at the Johns Hopkins University School of Medicine have uncovered for the first time molecular circuitry associated with schizophrenia that links three previously known, yet unrelated proteins.

Issues on cholesterol: diet, statins and genetics

Genetic lipoprotein disorders are frequently seen in patients with premature coronary artery disease (CAD). An example of strong genetic predisposition is the disorder: familial hypercholesterolemia, where a single gene defect (the low density lipoprotein receptor) contributes to most of the familial expression of CAD.

Anti-itching drug clemizole shows promise against hepatitis C

The fight against the liver disease hepatitis C has been at something of an impasse for years, with more than 150 million people currently infected, and traditional antiviral treatments causing nasty side effects and often falling short of a cure. Using a novel technique, medical and engineering researchers at Stanford University have discovered a vulnerable step in the virus' reproduction process that in lab testing could be effectively targeted with an obsolete antihistamine.

Blood vessel cells are instructed to form tube-like structures

How do blood vessel cells understand that they should organise themselves in tubes and not in layers? A research group from Uppsala University shows for the first time that a special type of "instructor" molecule is needed to accomplish this. These findings, published in the scientific journal Blood, might be an important step towards using stem cells to build new organs.

Why transplanted insulin cells die

New research can enhance survival of islets transplants and improve treatment of type 1 diabetes. Transplantation of insulin-producing cell islets, so-called islets of langerhans is an appealing strategy for treatment of type 1 diabetes. But it turns out that these are short-lived, and the procedure needs to be repeated.

Gleevec receives FDA priority review for gastrointestinal stromal tumors after surgery

Novartis has announced that Gleevec (imatinib mesylate) tablets, (known as Glivec (imatinib) outside the US, Canada and Israel), has been granted priority review status by the US Food and Drug Administration (FDA) as the first therapy to be reviewed for use after surgery in kit-positive gastrointestinal stromal tumors (GIST).

Young type-2 diabetic men suffer low testosterone levels

Young men with type 2 diabetes have significantly low levels of testosterone, endocrinologists at the University at Buffalo have found -- a condition that could have a critical effect on their quality of life and on their ability to father children.

Breastfeeding could reduce risk of aggressive form of breast cancer that disproportionately affects black, younger women

Breastfeeding for at least six months might lower the risk of developing so-called "triple negative" breast cancer, an aggressive form of the disease that is more common in black and younger women, according to a study published on Monday in the journal Cancer, the Seattle Post-Intelligencer reports (Paulson, Seattle Post-Intelligencer, 8/24).

Normalizing tumor vessels to improve chemotherapy drug delivery

Chemotherapy drugs often never reach the tumors they're intended to treat, and radiation therapy is not always effective, because the blood vessels feeding the tumors are abnormal-"leaky and twisty" in the words of the late Judah Folkman, MD, founder of the Vascular Biology program at Children's Hospital Boston.
