A potent suppressor of endometrial cancer is revealed (February 14, 2010) -- Treatment of endometrial cancer has not advanced significantly in 30 years and there are no screening tests to promote early detection. Researchers have developed a new approach to specifically target genetic changes to the endometrial cells in mice. Using this new technique, they show that loss of an emerging tumor suppressor causes abnormal growth and widespread malignancy of cells lining the uterus. ... > full story
Diabetes drug ups risk for bone fractures in older women, study suggests (February 14, 2010) -- A new study finds women with type 2 diabetes who take a commonly prescribed class of medications to treat insulin resistance may be at a higher risk for developing bone fractures. After taking a thiazolidinedione (TZD) for one year, women are 50 percent more likely to have a bone fracture than patients not taking TZDs, according to study results. And those at the greatest risk for fractures from TZD use are women older than 65. ... > full story
Assistive technology helps dementia sufferers get through the day (February 14, 2010) -- Tens of millions of elderly people in the EU suffering from mild dementia may be able to look after themselves, and free up their carers, thanks to a new system. ... > full story
Genetic secrets to jumping the species barrier (February 13, 2010) -- Scientists have pinpointed specific mutations that allow a common plant virus to infect new species. Understanding the genetics of the key interactions between viruses and hosts could provide insight to how some viruses manage to jump the species barrier and even give us a better idea of how animal diseases are generated. ... > full story
Restrictions on female plasma may not be warranted (February 13, 2010) -- Three years after the US blood banking industry issued recommendations that discourage transfusing plasma from female donors because of a potential antibody reaction, researchers discovered that female plasma actually may have advantages. ... > full story
The biggest loser: Maternal obesity puts a load on her offspring that lasts a lifetime (February 13, 2010) -- As if there are not enough reasons for obese people to lose weight, a new research report adds several more. In a study involving rats, researchers found that obesity in mothers causes cellular programming in utero that predisposes offspring to inflammation-related disorders (such as Alzheimer's, Parkinson's, type 2 diabetes, stroke, heart disease and more) from birth, regardless of whether or not the offspring are obese themselves. ... > full story
Muscle loss finding may one day save physiques (February 13, 2010) -- Mice that lack a particular antioxidant enzyme show impairment of cell energy centers called mitochondria. This leads to smaller and weaker muscles, and may help scientists better understand age-related muscle atrophy and other neuromuscular diseases. ... > full story
Epigenetic signals differ across alleles (February 13, 2010) -- Researchers have identified numerous novel regions of the genome where the chemical modifications involved in controlling gene expression are influenced by either genetic variation or the parental origin of that particular stretch of DNA. This contradicts previous assumptions that epigenetic signals are generally equal across both copies of a given region of the genome, except at a small number of known imprinted genes. ... > full story
Male college students also victims of violence at girlfriends' hands (February 13, 2010) -- Researchers are looking at the impact that being a victim of violence has on male versus female college students in heterosexual relationships. They that found the biggest predictor of whether male and female college students would use violence against a partner was whether the partner was violent toward them. ... > full story
Scientists synthesize unique family of anti-cancer compounds (February 13, 2010) -- Scientists have streamlined the process for synthesizing a family of compounds with the potential to kill cancer and other diseased cells, and have found that they represent a unique category of anti-cancer agents. ... > full story
Low levels of natural antibodies behind stroke (February 13, 2010) -- The chances of suffering a stroke are linked to the presence of a certain type of antibody in the immune system, a new study from Sweden shows. The researchers hope to be able to develop a vaccine that can mobilize the body's own defense against arteriosclerosis and stroke. ... > full story
Role of protein pair in obesity regulation (February 13, 2010) -- New research implicates a new protein in obesity development and highlights a protein pair's "team effort" in regulating obesity and insulin resistance. ... > full story
