Bone loss in women with breast cancer may not be prevented by calcium supplements
Date: Aug-30-2013Women undergoing treatment for breast cancer are widely prescribed calcium and vitamin D supplements to prevent and manage osteoporosis, an unwanted side effect of breast cancer therapies. However, new research from Wake Forest Baptist Medical Center finds that the recommended daily doses of these supplements may not prevent loss of bone mineral density (BMD) in these women. Study author Gary G. Schwartz, Ph.D., a cancer epidemiologist at Wake Forest Baptist, said the purpose of the study was to examine whether a seemingly common sense prescribing practice actually works...
New 3D scanner reveals what high heels really do to feet
Date: Aug-30-2013For most women, wearing high heels is a must. But although they look good, there is no denying the pain they can cause. Now, researchers have created a 3D scanner that shows exactly why high heels cause so much pain, and what damage they can cause to feet and ankles. A research team at the Royal National Orthopedic Hospital (RNOH) created the new 3D scanner, which they say is set to transform how foot and ankle problems are diagnosed...
Skin self-exams recommended for Hispanics
Date: Aug-30-2013More than three-quarters of Hispanics patients in North Carolina aren't performing skin self-exams (SSE) to detect possible skin cancers, and physicians need to do a better job of educating their patients about this potentially life-saving practice, say researchers in the School of Medicine at the University of North Carolina at Chapel Hill. Study results were reported earlier this year in the Research Letters section of the Archives of Dermatology. [Nota: Una versión español de este comunicado de noticia llega tras la versión Inglés...
The cerebral cortex is the brain region where memory associations are linked and stored - not the hippocampus
Date: Aug-30-2013'Where' and 'how' memories are encoded in a nervous system is one of the most challenging questions in biological research. The formation and recall of associative memories is essential for an independent life. The hippocampus has long been considered a centre in the brain for the long-term storage of spatial associations. Now, Mazahir T...
Young women who experience dating violence face economic barriers
Date: Aug-30-2013Dating violence in adolescence not only takes a physical and emotional toll on young women, it also leads to less education and lower earnings later in life, according to a first-of-its-kind study led by a Michigan State University researcher. A young woman's educational performance may be hindered by her partner's actions, such as destroying books or homework or causing injuries that prevent her from going to school...
Recommended hybrid screening strategy for colorectal cancer
Date: Aug-30-2013A strategy that combines two effective colorectal cancer screening methods, fecal immunological test and colonoscopy, may improve prevention and detection of colorectal cancer and reduce costs, according to a new study in Clinical Gastroenterology and Hepatology (CGH), the official clinical practice journal of the American Gastroenterological Association. The study used a simulation model to test a hybrid screening strategy consisting of annual or biennial fecal immunological test at younger ages (50 to 65 years of age), combined with a single colonoscopy when the patient is 66 years old...
Promising therapeutic target for hard-to-treat brain tumor
Date: Aug-30-2013Johns Hopkins researchers say they have found a specific protein in nearly 100 percent of high-grade meningiomas -- the most common form of brain tumor -- suggesting a new target for therapies for a cancer that does not respond to current chemotherapy. Importantly, the investigators say, the protein -- NY-ESO-1 -- is already at the center of a clinical trial underway at the National Cancer Institute. That trial is designed to activate the immune systems of patients with other types of tumors that express the protein, training the body to attack the cancer and eradicate it...
Maximizing the safety of in vivo testing
Date: Aug-30-2013New classes of therapeutic antisense oligonucleotides can have toxic effects on the liver. A novel machine learning-based approach used to predict the hepatotoxic potential of an antisense drug based on its chemical sequence is presented in Nucleic Acid Therapeutics, a peer-reviewed journal from Mary Ann Liebert, Inc. publishers. The article is available on theNucleic Acid Therapeutics website...
Changing attitudes among young footballers towards gay teammates
Date: Aug-30-2013Young footballers on the verge of becoming professionals are now much more likely to be supportive of gay teammates than a decade ago, according to new research from sociologists at the universities of Kent and Winchester. Conducted via interviews with 22 Premier League academy footballers aged 16-18, the research found that all the participants would openly accept one of their colleagues coming out...
Barber Pole worm genome provides an essential platform to understand drug resistance in parasitic worms
Date: Aug-30-2013Researchers have identified five enzymes that are essential to the survival of a parasitic worm that infects livestock worldwide and is a great threat to global food security. Two of these proteins are already being studied as potential drug targets against other pathogens. The team sequenced the genome of Haemonchus contortus, or the barber pole worm, a well-studied parasitic worm that resides in the gut of sheep and other livestock globally...
