Ph.D. candidate Lital Alfonta wins Kaye Award

Lital Alfonta, a Ph.D. candidate in the Faculty of Science at the Hebrew University of Jerusalem, has developed a fast, inexpensive test to determine if an AIDS patient has developed resistance to the medication he is taking. Ms. Alfonta was selected to receive the prestigious Kaye Innovation Award for her work, which could vastly improve treatment of AIDS patients.

Ms. Alfonta, who developed the test under the guidance of Prof.

Rising levels of gonorrhoea and syphilis across western Europe since 1995 imply that complacency over HIV prevention efforts may have set in among individuals and some governments, argue researchers in this week’s BMJ.

Angus Nicoll and Francoise Hamers examined national trends in diagnosed HIV infections, gonorrhoea, and infectious syphilis from 1995 to 2000.

They found the numbers of new diagnoses of sexually acquired HIV infections increased by 20% in western Europe. Rates of go

Popular arthritis drugs, known as selective COX 2 inhibitors, may not be superior to traditional non-steroidal anti-inflammatory drugs, conclude researchers in this week’s BMJ.

A study published in September 2000 concluded that the COX 2 inhibitor, celecoxib, was associated with a lower rate of stomach and intestinal ulcers than two older drugs for arthritis. However, only data for the first six months of the study were published. When all the data were considered, the published results appe

Scientists from Imperial College London have discovered that xenon gas could help in protecting damaged nerve cells.

The research, published today in Anesthesiology, shows that xenon, an inert gas, acts as a neuroprotectant, helping to protect damaged nerve cells from dying. Based upon pre-clinical trials, researchers believe it could have human applications, eventually leading to treatments for people suffering from nerve damaging illnesses, such as strokes, and brain and spinal cord injur

Authors of a research letter in this week’s issue of THE LANCET describe a new technique where the detection of a specific protein in faeces could be a marker for colorectal cancer.

Colorectal cancer is a common disease (causing around 500,000 deaths each year worldwide), and screening methods that are more reliable than colonoscopy and faecal-blood assessment are needed for earlier disease detection. Nicholas Coleman and colleagues from the MRC Cancer Cell Unit, Cambridge, UK, aim to develo

Giving magnesium sulphate injections to pregnant women with pre-eclampsia halves the risk of eclampsia developing and can save their lives. This is the conclusion of a major international clinical trial funded by the Medical Research Council (MRC) and published in this week’s The Lancet.

The three-year £2.5 million study, the ‘Magpie’* Trial, was conducted in 33 countries spanning the UK and much of the developing world where eclampsia is the most common cause of death for pregnant women. Th
