Their discovery shows positive effects of drugs that may lead to effective new treatments for the neurodegenerative disease. iPSC are made from patient skin cells rather than from embryos and can become any type of cells in the laboratory. http://medicalxpress.com/news/2013-05-stem-cell-treatment-rare-genetic.html Diseases, Conditions, Syndromes Fri, 10 May 2013 13:40:50 EST news287412041 A new, free iPad application developed at UCLA helps women navigate through the sometimes confusing process of selecting a birth control method without sacrificing quality of information. The app is appealing to look at, easy to use, and highlights the most effective types of birth control, while also revealing any potential side effects, risks and warning signs. http://medicalxpress.com/news/2013-05-mobile-health-app-birth-method.html Obstetrics & gynaecology Wed, 08 May 2013 15:56:50 EST news287247403 (Medical Xpress)—Subway may promote itself as the "healthy" fast food restaurant, but it might not be a much healthier alternative than McDonald's for adolescents, according to new UCLA research. http://medicalxpress.com/news/2013-05-adolescents-subway-food-healthier-mcdonald.html Health Wed, 08 May 2013 07:08:25 EST news287215697 (Medical Xpress)—Very little has been known about the epigenetic events—developmental and environmental factors affecting genes—that occur prior to the invasive growth of head and neck squamous cell carcinomas and their spread to other parts of the body, or metastasis. http://medicalxpress.com/news/2013-05-trigger-neck-cancer-cells.html Cancer Wed, 08 May 2013 07:07:36 EST news287215646 (Medical Xpress)—UCLA life scientists have identified a gene previously implicated in Parkinson's disease that can delay the onset of aging and extend the healthy life span of fruit flies.
