Sexual Content In Films Affects Adolescent Sexual Behavior
Date: Jul-27-2012Young people who watch more sexual content from movies also tend to engage in more sexual behavior and begin sexual activity at an earlier age, according to a University of Missouri researcher's study. "We can't say that watching sexual content in movies is directly responsible for adolescents' sexual behavior," said Ross O'Hara, currently a post-doctoral fellow at the University of Missouri, who conducted the research with other psychological scientists while at Dartmouth College. "However, there is a correlation between the two...
Blood Vessels Created In The Lab Using Adult Stem Cells From Liposuction
Date: Jul-27-2012Adult stem cells extracted during liposuction can be used to grow healthy new small-diameter blood vessels for use in heart bypass surgery and other procedures, according to new research presented at the American Heart Association's Basic Cardiovascular Sciences 2012 Scientific Sessions. Millions of cardiovascular disease patients are in need of small-diameter vessel grafts for procedures requiring blood to be routed around blocked arteries...
START Analysis Of Terrorism And The Olympics
Date: Jul-27-2012History offers a warning, but no clear pattern on the true risk of terrorism at the Olympic Games, concludes a new report by the National Consortium for the Study of Terrorism and Responses to Terrorism (START) based at the University of Maryland. The Olympic Games have been terror targets on three separate occasions since 1970, claiming 22 lives and wounding more than 100, the report says. It compiles and analyzes data from START's comprehensive Global Terrorism Database (GTD)...
Mouse Model Of Inherited Heart Disease And Muscular Dystrophies Responds Well To Rapamycin
Date: Jul-27-2012Rapamycin, an immunosuppressant drug used in a variety of disease indications and under study in aging research labs around the world, improved function and extended survival in mice suffering from a genetic mutation which leads to dilated cardiomyopathy (DCM) and rare muscular dystrophies in humans. There are currently no effective treatment for the diseases, which include Emery-Dreifuss Muscular Dystrophy and Limb-Girdle Muscular Dystrophy. The familial form of DCM often leads to sudden heart failure and death when those affected reach their 40's and 50's...
Congenital Deafness May Be Reversed By Gene Therapy
Date: Jul-27-2012A new gene therapy approach can reverse hearing loss caused by a genetic defect in a mouse model of congenital deafness, according to a preclinical study published by Cell Press in the journal Neuron. The findings present a promising therapeutic avenue for potentially treating individuals who are born deaf...
Children On Low-Protein Diet Predisposed To Hypertension In Adulthood
Date: Jul-27-2012Studies have shown that the offspring of mothers on a low-protein diet are more likely to develop hypertension as adults. Now, Drs. Gao, Yallampalli, and Yallampalli of the University of Texas Medical Branch at Galveston report that in rats, the high maternal testosterone levels associated with a low-protein diet are caused by reduced activity of an enzyme that inactivates testosterone, allowing more testosterone to reach the fetus and increase the offspring's susceptibility to adulthood hypertension...
Nerve Damage And Locally Produced Proteins
Date: Jul-27-2012Several years ago, Prof. Michael Fainzilber and his group in the Biological Chemistry Department made a surprising discovery: Proteins thought to exist only near the cell nucleus could also be found in the far-off regions of the body's longest cells - peripheral nerve cells that extend processes called axons, reaching up to a meter in length in adult humans. These proteins, known as importins, have a well-studied role in the vicinity of the nucleus: They shuttle various molecules through the protective nuclear membrane...
New Study Finds Evidence Of Memory Impairments With 1 Year Of Recreational Use Of Ecstasy
Date: Jul-27-2012There has been significant debate in policy circles about whether governments have over-reacted to ecstasy by issuing warnings against its use and making it illegal. In the UK, David Nutt said ecstasy was less dangerous than horseback riding, which led to him being fired as the government's chief drug advisor. Others have argued that ecstasy is dangerous if you use it a lot, but brief use is safe. New research published online by the scientific journal Addiction, gives some of the first information available on the actual risk of using ecstasy...
New HIV Prevention Approach For Women: Phase III Trial Of Dapivirine Ring Has Begun In Africa
Date: Jul-27-2012A large clinical trial testing the long-term safety and effectiveness of a new approach for preventing HIV in women - a vaginal ring used once a month - is now underway in Africa, researchers announced at the XIX International AIDS Conference (AIDS 2012). ASPIRE - A Study to Prevent Infection with a Ring for Extended Use - is a Phase III trial evaluating a vaginal ring that contains dapivirine, a potent antiretroviral (ARV) drug originally developed to treat HIV...
Risk Of Endometrial Cancer Reduced In Women Who Give Birth After Age 30
Date: Jul-27-2012Women who last give birth at age 40 or older have a 44 percent decreased risk of endometrial cancer when compared to women who have their last birth under the age of 25, according to strong evidence in a new, international study led by a researcher at the Keck School of Medicine of USC. Endometrial cancer strikes the endometrium, the tissue lining the uterus (womb), and is the most common gynecological cancer in the United States. Veronica "Wendy" Setiawan, Ph.D...
