Washington, Sept 17 : A team of scientists from Yerkes National Primate Research Center and the Emory Vaccine Center has reached a step closer to determining why SIV and HIV infection leads to AIDS in some primate species but not others.

Studying the mangabeys, the natural hosts for the AIDS viruses that remain healthy despite SIV infection, the researchers have found that their immune systems are activated to a significantly lower extent during the infection than are the immune systems of rhesus macaques.

The researchers say that this difference may explain why SIV and HIV infection leads to AIDS in some primate species but not others.

Melbourne, Sept 17 : An increasing number of women in generation Y age group have become a victim of chlamydia, a sexually transmitted infection (STI) that can cause infertility, according to a sexual health researcher, who describes it as a "little epidemic".

Researcher and lecturer Dr Melissa Kang said the rates of chlamydia infections have significantly increased in the Gen Ys over the past decade.

The cases of chlamydia has quadrupled from 1999 to 2007 and the most affected were young women aged 20 to 24

The cases increased from 335 per 100,000 people in 1999, to 1300 per 100,000 people in 2007.

Women and girls aged between 15 and 19 had the second highest rate and young men aged 20 to 24 the third.

Melbourne, Sept 17 : Consuming alcohol can be good for your heart, but you have to be a lazy smoker with an aversion to fruit and vegetables to reap the full benefits, suggests a Brit researcher.

UK’s leading researcher on the link between health and behaviour, the Australian expatriate Michael Marmot, found that smokers with the worst diets and poorest exercise habits could consume as many as 14 standard drinks a week, and still cut the risk of having a heart attack, stroke or other form of cardiovascular disease.

Greater quantities were less beneficial, though still better for those people than being teetotal.

Case of Niketa Mehta brought Medical Termination of Pregnancy (MTP) Act under public eye. The 37-year old MTP Act, allows termination of pregnancy from 12 to 20 weeks, if two medical practitioners are of opinion that “there exists a substantial risk that, if the child were born it would suffer from physical or mental abnormalities so as to be seriously handicapped.”

Sleep Apnea in men, is also linked to erectile dysfunction(ED). A recent research by researchers from the University of Louisville, has offered a hope regarding treatment of erectile dysfunction(ED). In patients suffering from obstructive sleep apnea syndrome (OSAS), ED is linked to the chronic intermittent hypoxia—oxygen deprivation (CIH) experienced during these episodes of obstructed breathing.

Dr. David Gozal, professor of pediatrics at the University of Louisville, said: “Even relatively short periods of CIH … are associated with significant effects on sexual activity and erectile function.”
