Protective factors may prevent alcoholism

Article Abstract:

Brain imaging techniques have helped scientists identify factors that may protect an individual with a genetic disposition to alcoholism from developing the disorder further. Scientists have discovered that high levels of certain receptors in the brain that regulate dopamine, a chemical involved in the brain's reward circuitry, may counteract a genetic disposition to alcoholism suggesting that medical or environmental interventions that boost [D.sub.2] receptor levels may be potential treatments.

Group backs emergency contraception

Article Abstract:

The American College of Obstetricians and Gynecologists (ACOG) has launched 'Ask Me', a campaign to educate women about emergency contraception and to encourage them to get an advance prescription from their physician in case they ever need it. Leaders from the ACOG, who launched the campaign in May 2006, believe that emergency contraception is an important component of family planning and better access to it might help reduce the number of unplanned pregnancies and abortions in the US.

Routine male circumcision could prevent millions of HIV infections in Africa

Article Abstract:

An analysis published by an international team of researchers in July 2006 revealed that routine circumcision of all men in Africa could prevent 2 million new HIV infections and avert 300,000 deaths over the next 10 years. The research team analyzed data from a randomized controlled reduced sexual transmission of HIV from women to men by 60% and data on the prevalence of circumcision and HIV infection in Africa to determine the potential impact of this intervention.
