Washington, April 17 : A new study suggests that the drugs used to treat sexual dysfunction in men may some say also address some forms of female sexual disorders.

Medical College of Georgia researchers Kyan J. Allahdadi, Rita C. Tostes, and R. Clinton Webb say that female sexual dysfunction may partly result from inadequate supply of blood to the female genitals, and that it may be addressed with erectile dysfunction drugs.

Originally developed as therapy for hypertension, such drugs work by dilating blood vessels sufficiently to produce erections in males.

London, Apr 17 : Scientists have found that the body comprises a cellular "First Aid" system for brain cells in which certain immune cells in the blood, called regulatory T lymphocytes (Treg), inhibit ischemic stroke-related inflammation.

Dr. Roland Veltkamp, senior physician at the Neurology Clinic of Heidelberg University Hospital, points out that the regulator cytokine interleukin 10 (IL 10) plays an important role in this protection, and that this work offers a new approach to stroke therapy.

London, Apr 17 : In what could be called a miracle, a 38-year-old Brit mum gave birth to healthy twins just minutes after suffering a massive heart failure.

Nina Whear gave birth to twins Evie and Alfie through caesarean section moments after her weeping husband bade her an emotional farewell.

Whear, of Lamas, Norwich, suffered heart failure two weeks before the babies were due on January 6.

Washington, April 17 : Swedish researchers have found that adults use brown fat to convert energy into heat, a finding that may lead to novel treatments for overweight and obesity.

Sven Enerback, Professor at the Institute of Biomedicine at the Sahlgrenska Academy, University of Gothenburg, points out that the brown fat found in infants is traditionally believed to disappear as a person grows up.

However, the researcher insists, the new study has shown the presence of brown fat cells in the lower part of the neck in adults, just above their collarbones.

During the study, the researchers tested the region of brown fat cells in the neck by placing five volunteers, in thin clothing, in a chilly room for a couple of hours.

Washington, April 17 : Scientists at the University of Washington have moved a step closer to developing more effective treatments for jet lag, by finding out that this problem disrupts sleep by upsetting internal clocks in two separate but linked groups of neurons in a structure in the brain called the suprachiasmatic nucleus.

The researchers have revealed that this structure lies below the hypothalamus at the base of the brain.

Washington, April 16 : A minimally invasive surgical approach has been found to have certain advantages that makes it a preferable treatment for some stomach cancer patients.
