Female condoms should be promoted as an effective solution to prevent the spread of HIV/AIDS

While scientists work to find the 'perfect' solution to preventing the spread of HIV/AIDS, a reasonable option--the female condom--is not being promoted, especially in African and southeast Asian countries where the deadly virus is most prevalent, according to a new study.

Carbon coatings to prevent bacteria collecting on indwelling catheters

This team of physicists have coated catheters and ureter stents with an extremely thin layer of diamond-like carbon. DLC-coated surfaces do not react chemically with their environment; they are hardwearing, can be sterilised and reduce friction.

Five advanced tests provide answers to couples with unexplained infertility

For couples struggling with infertility, "all routine tests came back negative" are not the words they want to hear. With up to 15% of couples with "unexplained infertility" and another 3% struggling with recurrent pregnancy loss, advanced tests help doctors find answers for their most challenging cases.

Silicone facial implants provide HAART patients with a healthier appearance

Highly active antiretroviral therapy (HAART) for the treatment of HIV/AIDS is the name given to treatment regimens recommended by leading HIV experts to aggressively suppress viral replication and progress of HIV disease. These treatment regimens have been shown to reduce the amount of virus so that it becomes undetectable in a patient's blood.

Carbon dioxide laser could be the fix for photoaging or skin damaged by the sun

Excessive exposure to the sun early in life can make a person look older than he/she really is. Premature wrinkling and skin damage from sun exposure is also called photoaging. Photoaging, unlike natural aging, results in course, dry skin, freckling, skin discoloration, leathery skin, and deep wrinkles.
