Both HIV-1 and HIV-2 are of zoonotic origin , and the closest simian relatives of HIV-1 and HIV-2 have been found in the common chimpanzee (Pan troglodytes) and the sooty mangabey (Cercocebus atys) respectively. Given that humans come in frequent contact with primates in many parts of subsaharan Africa, particularly through hunting and handling primate bushmeat the possibility of additional zoonotic transfers of primate lentiviruses from species other than chimpanzees and sooty mangabeys has to be co

Scientists have developed a blood test that may reveal changes in the brain caused by Alzheimer’s disease. The technique, tested so far only in mice, predicts the amount of amyloid plaque (formed from clumps of proteins that kill surrounding cells) in an animal’s brain. The research, detailed in a report in the current issue of the journal Science, holds promise for the development of predictive methods to diagnose the disease years ahead of the onset of clinical symptoms.

Women with early breast cancer could avoid needless chemotherapy thanks to work carried out in Chicago on identifying biochemical markers which indicate whether or not cancer is likely to spread to other parts of the body, the 3rd European Breast Cancer Conference in Barcelona heard today (Saturday 23 March).

Ruth Heimann, Associate Professor in the department of radiation and cellular oncology at the University of Chicago, USA, said that patients with early breast cancer which has not sprea

The first clinical trial in Europe of a revolutionary approach to diagnosing breast cancer has just got under way at one of the UK’s leading breast cancer centres.
The research involves a minute endoscope, no thicker than a few strands of human hair, which can pass through the nipple and search for the earliest signs of cancer within the breast.

Consultant breast surgeon, Dr Nicolas Beechey-Newman from Guy’s Hospital in London, told a news briefing at the 3rd European Breast Cancer Confe

Swedish stem cell researchers are in a good position to become even more successful than in recent years. This can be achieved by improving the collaboration between research groups, and by increasing the number of researchers in the field through, for example, the introduction of “come-home” grants for those who have been abroad. Equally important would be economic commitment to basic research on stem cells, and the creation of regulations for emergent commercial aspects so that researchers can main

An anti-oestrogen compound, discovered only four years ago, has been found to inhibit the growth of breast cancer cells using a unique mechanism which enables it to work against tumours that are resistant to other anti-oestrogens, the 3rd European Breast Cancer Conference in Barcelona heard today (Thursday 21 March).

Yasuji Yamamoto, from the Institute of Molecular and Cellular Biosciences at the University of Tokyo in Japan, said the compound, known as TAS-108, was being assessed in phase l
