Study of gene transfer for erectile dysfunction shows promise
The first human study using gene transfer to treat erectile dysfunction (ED) shows promising results and suggests the potential for using the technology to treat overactive bladder, irritable bowel syndrome and asthma, according to the researchers. "In the small pilot study, this new therapy was well tolerated and safe," said George Christ, Ph.D., senior researcher and a professor at the I...'Erectile dysfunction' drugs heighten natural anti-cancer activity
Sildenafil and other "impotence drugs" that boost the production of a gassy chemical messenger to dilate blood vessels and produce an erection now also show promise in unmasking cancer cells so that the immune system can recognize and attack them, say scientists at the Johns Hopkins Kimmel Cancer Center. Tests at Hopkins on mice with implanted colon and breast tumors showed that tumor size...Protein may hold key to decreasing organ dysfunction rates in heart transplants
A new study, led by Felix Aigner, M.D., has identified a protein known as Lipocalin-2 (Lcn-2) as potentially responsible for regulating the body's inflammatory response during heart transplants. One of the major complications involved with many transplantations is the damage done to the transplanted heart during and immediately following surgery, known as ischemia and reperfusion (IR). In particu...Erectile dysfunction in diabetes is due to selective defect in the brain
A new study sheds additional light on how erectile dysfunction (ED) interacts with diabetes. The study is another step in uncovering the link between the two disorders, and may lead to improved efficacy in treatments. The study, "Lack of Central Nitric Oxide Triggers Erectile Dysfunction in Diabetes," was conducted by Hong Zheng, William G. Mayhan, and Kaushik P. Patel, Departments of Cel...Gene therapy delivery of nerve growth factors reverses erectile dysfunction in animal model
Rats with erectile dysfunction, or ED, that were injected with a gene therapy vector containing either of two nerve growth factors were able to regain normal function after four weeks, according to a study conducted by University of Pittsburgh School of Medicine researchers. These findings are being presented at the 10th annual meeting of the American Society of Gene Therapy, which is convenin...Women suffer from sexual dysfunction too
Millions of postmenopausal women suffer from sexual dysfunctions- painful intercourse, sexual dissatisfaction and a multitude of physiological and psychological problems. However if the patients and their doctors communicated better, most of these problems can be treated properly. Almost all women, as they go through menopause, will gradually develop changes in genital organs-particularl...Hypertensive Drug Improves Sexual Dysfunction in Hypertensive Men
Losartan, a new anti hypertensive drug appears to improve sexual function among the hypertensive men with erectile dysfunction. As the cause of impotence, really it is the disease process itself, probably from reduced vascular compliance. According to American Journal of Medical sciences, a study evaluated hypertensive men with erectile dysfunction and found that their overall sexual sat...New dimension in the treatment of female sexual dysfunction
Female sexual dysfunction is associated with loss of libido, low motivation and fatigue, most often occurring in women who have attained their menopause or whose ovaries had been removed surgically for some reason. Dehydroepiandosterone(DHEA), may serve as an effective treatment in such sexual dysfunction, according to a study released at the 96th annual meeting of the American Urologica...Moderate Use of Analgesics - Not Associated With Kidney Dysfunction
According to a new study, occasional use of aspirin, acetaminophen, or other pain relievers for everyday aches and pains is not associated with kidney dysfunction among healthy men. As analgesic use is so common, even small increases in the relative risk of renal dysfunction could have a significant impact on rates of renal disease. Some earlier studies have suggested that regul...Control of anger disorder connected to Brain Dysfunction
According to a study, the scientists have bound dysfunction in a particular brain region to a psychiatric disorder marked by uncontrolled aggression. They say their findings extend the link that has been found between the brain area--called the orbital/medial prefrontal cortex circuit,// or OMPCC and impulsive aggression. In this case, the researchers studied 30 patients diagnosed with...
