OHSU study suggests that HRT may act on cancer cells to produce less aggressive tumors

A study of nearly 300 breast cancer patients at Oregon Health & Science University found that women who use hormone replacement therapy (HRT) have less aggressive tumors and are more likely to be diagnosed through mammograms than other methods. Also, HRT users with breast cancer had significantly better survival rates than non-HRT users. The study is published in the September issue of the journal T

The same sanitizing agent used to rid federal office buildings of anthrax – chlorine dioxide gas – can effectively eliminate deadly bacteria from apples and other fruits and vegetables, according to Purdue University researchers.

Scientists at Purdue began experiments using the gas to kill pathogens found on food long before anthrax was detected in mail sent to offices in New York and Washington, D.C., shortly after the terrorist attacks one year ago. The latest university test measured how

The use of drugs/pharmaceuticals in cattle rearing is the object of a recent study, carried out by two researchers from the Centro de Estudos Farmacêuticos, Laboratório de Bromatologia, Hidrologia e Nutrição (Pharmaceutical Study Centre, Bromatology, Hydrology and Nutrition Laboratory) at the Pharmacy Faculty of Coimbra University. The consequences for consumers are, from a public health standpoint, the most significant conclusions to take from an exhaustive work of literary revision in these matters

A study by the coordinator of the Research Group on Climate at the Barcelona Science Park, University of Barcelona, Dr Xavier Rodó, and other researchers at the University of Michigan and the International Center for Diarrhoeal Disease Research in Bangladesh, provides evidence not only that climatic variation associated with the El Niño-Southern Oscillation (ENSO) affects the appearance of cholera epidemics, as shown by a previous publication in Science by the same group, but also that the relationsh

Cancer develops from a single damaged cell subsequent to an accumulation of genetic errors in a number of its genes. The nature of these alterations and the order in which they occur differ from one cancer to another : hence, the “pathways” that may lead to cancer are numerous.

CNRS and INSERM researchers at the Institut Curie have just discovered a new tumor development pathway in colon cancer, one of the most common forms of cancer (35,000 new cases every year in France).

Highly Active Antiretroviral Therapy, or HAART, is the standard of care for HIV/AIDS patients and has prolonged the lives of countless persons with the disease. HAART has been associated, however, with the emergence of lipodystrophy syndromes. In this month’s issue of the journal Mitochondrion*, researchers from the National Cancer Institute (NCI), the National Institute of Standards and Technology (NIST), and Purdue University, West Lafayette, Ind., report that protease inhibitors, a component
