New research shows that women suffering from Persistent Genital Arousal Disorder (PGAD), a condition marked by unprovoked, intrusive and persistent sensations of genital arousal that are unrelieved by one or several orgasms, are likely to experience a variety of associated psychological conditions.
Women who have this rare and often distressing condition often experience related depression, anxiety, panic attacks and frequently show a past history of sexual victimization. The condition is accompanied by frustration, guilt, anxiety and distress for the sufferer. The first-ever study on PGAD…

Research about to published in the journal Molecular Psychiatry, resulting from a collaboration between scientists in Germany, Portugal and the UK, suggests that stress contribute directly to the development of Alzheimer’s disease (AD).
According to the results now published, stress induces the production of amyloid beta (Ab) peptide – the molecule associated with the neural plaques characteristic of the disease – and also makes neurons more vulnerable to Ab toxicity. Administration of glucocorticoids (GC) - the production of which is the first physiological response to stress – was shown…
For older patients with end-stage renal disease (ESRD), the results of kidney transplants from "expanded criteria non-beating-heart" donors are not good, according to a paper presented at the American Society of Nephrology's 40th Annual Meeting and Scientific Exposition in San Francisco.
Led by Dr. Jagbir Gill of University of California Los Angeles, the researchers analyzed the outcomes of nearly 31,000 patients aged 60 or older who received deceased-donor kidney transplants in the United States between 1995 and 2006. Data for the study came from the Organ Procurement and Transplantation…
Nursing mothers needn't worry. A new study shows that breastfeeding does not increase breast sagging. University of Kentucky plastic surgeon Dr. Brian Rinker and his colleagues conducted the study with patients at UK HealthCare Cosmetic Surgery Associates. The study found that breastfeeding does not adversely affect breast shape.
"A lot of times, if a woman comes in for a breast lift or a breast augmentation, she'll say 'I want to fix what breastfeeding did to my breasts'," Rinker said. As a result, Rinker decided to find out if breast sagging was a direct result of breastfeeding.

The shortage of islet cells limits the development of islet transplantation. One new approach was reported in the October 21 issue of the World Journal of Gastroenterology because of its great significance in enhancing the output of islet cells.
The article describes the differentiation of rat pancreatic ductal epithelial cells into insulin-producing cells by the transfection of PDX-1. In recent years, though great efforts have been made to differentiate embryonic stem cells, pancreatic ductal epithelial multipotent progenitor cells and bone marrow stem cells into islet cells, the process of…
Gold really does make you feel better, and not just because you can buy things to make misery more tolerable. Scientists at Duke University Medical Center say new insight into the healing properties of gold may renew interest in gold salts as a treatment for rheumatoid arthritis and other inflammatory diseases.
Physicians first used injections of gold salts in the early 1900s to ease the pain and swelling associated with arthritis. But treatment came at a high cost: The shots took months to take effect and side effects included rashes, mouth sores, kidney damage and occasionally, problems…
Researchers have found that vaccination against influenza strains seems to be more effective in a semi-urban population than in a rural population of schoolchildren in Gabon, Africa, according to an article in the Dec. 1 issue of The Journal of Infectious Diseases. The study suggests that infection with parasites and/or poor nutrition may have an impact on the effectiveness of influenza vaccine.
Lead author E. van Riet (Department of Parasitology, Leiden University Medical Center, Leiden, The Netherlands) and a team of researchers analyzed antibody and cellular responses to influenza A and B…
A clinical trial evaluating a brain cancer vaccine in patients with newly diagnosed brain cancer has begun at NYU Medical Center. The study will evaluate the addition of the vaccine following standard therapy with surgery and chemotherapy in patients with glioblastoma multiforme, a deadly form of brain cancer.
The vaccine, called DCVax-Brain, incorporates proteins found in patients’ tumors and is designed to attack cancer cells containing these proteins. The study underway at NYU Medical Center is an expansion of an earlier phase I trial of the vaccine. The vaccine is made by the Northwest…
While acne is oftentimes as much a part of being a teenager as dating and Friday night football games, a new study examining the prevalence of acne in adults age 20 and older confirms that a significant proportion of adults continue to be plagued by acne well beyond the teenage years. In particular, women experience acne at higher rates than their male counterparts across all age groups 20 years and older.
In the study entitled, “The prevalence of acne in adults 20 years and older,” published online in the Journal of the American Academy of Dermatology, dermatologist Julie C. Harper, MD,…
Responding to media reports of recent studies that emphasized the dangers of angioplasty in women compared to men, Dr. Alexandra J. Lansky, MD, Director of the Angiographic Core Laboratory and the Women's Cardiovascular Health Initiative at the Cardiovascular Research Foundation, said that the comparison to men overshadows the true benefit to women of early intervention.
“We should be comparing interventional strategies in women to other therapies in women, in order to determine whether or not they are beneficial. The comparison to men is largely irrelevant,” says Lansky.
“Recent news…
