Viral DNA sequence a possible trigger for breast cancer

A small sequence of DNA in the envelope (Env) protein of a mouse breast tumor virus (called MMTV) can transform breast cells into cancer cells, according to a study by Katz et al. in the February 7 issue of The Journal of Experimental Medicine. The ability of this motif to transform cells single-handedly suggests that viral infection may be an important and previously unrecognized trigger for bre...

New push for public health, AIDS spending at African Union summit

Activists hope this weekend's African Union (AU) summit will net commitments to boost government spending on public health, helping to curb the spread of AIDS, which killed 2.3 million Africans in 2004.

UAB scientists discover the origin of a mysterious physical force

Ever since the 1970s, scientists have been trying to establish the cause of a repulsive force occurring between different electrostatically charged molecules, such as DNA and other biomolecules, when they are very close to each other in aqueous media. This force became know as hydration force. Jordi Faraudo, a researcher for the Department of Physics at the Universitat Autònoma de Barcelo...

Columbia research lifts major hurdle to gene therapy for cancer

New Drug for Bronchial Asthma

Well, we thought that we had antibodies for just about everything well, we have an anti-IgE antibody now for bronchial asthma. This is particularly useful in bronchial asthma where an attack can be brought by a number of noxious and non-noxious stimuli. This has also been proven to induce symptomatic relief.How does that apply to the Indian context? Well, first we can try by ridding ourse...

Rapid Whole Blood Testing for Infectious Mononucleosis Antibodies

The Epstein Barr virus (EBV), which causes infectious mononucleosis (IM), is one of the most common human viruses. EBV occurs worldwide, and most people become infected with EBV sometime during their lives. In the United States, as many as 95 percent of adults between 35 and 40 years of age have been infected. In most developed countries, including the U.S., infection with EBV most often occu...

Bench-Top Centrifuges--Basic Tools for the Small Lab

No matter how elementary or advanced, every clinical laboratory possesses one essential devicea centrifuge.
