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. "We are definitely optimistic that this time there will be some movement, that this time there will be not just talk about an HIV strategy for the AU but how to tackle an action-oriented p...FDA Approves Human Hookworm Vaccine for Phase I Safety Trials

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
Researchers at Columbia University MedicalCenter have discovered a way to overcome one of the major hurdles ingene therapy for cancer: its tendency to kill normal cells in theprocess of eradicating cancer cells.In a new study published in the Jan. 25 issue of the Proceedings of theNational Academy of Sciences (PNAS), the researchers demonstrated thatthe technique works by incorporating it i...S. cerevisiae Direct Transformation Kit from Wako Chemicals USA, Inc.

Arthritis causes inflammation of a joint or joints and the surrounding tissues and affects millions of people all over the world. Anti-arthritic drugs can cause side effects and surgery can be expensive, however there is hope from a natural product liquid glucosamine and chondroitin sulfates. Some excellent results with an approach based on a combination of the two supplements have been r...Bypass Heart Surgery Performed Without General Anesthesia
A minimally invasive direct coronary artery bypass (MIDCAB) procedure was performed at Pittsburgh while the patient was awake. The operation was done under thoracic epidural anesthesia. This approach may help in discharging the patient early from the hospital. Dr. Zenati from the team of doctors who performed the surgery said that patients who are operated in this way may not have to go t...Hasford Double Ended Lacrimal Dilator

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. It may be a bench-top or floor model, refrigerated or non-cooled, but this apparatus, because of its unique ability to fractionate liquid specimens by creating spin-induced high g-forces, has long been a standard tool for both diagnosis and research applications. For all this utility, t...Monitoring Options Expand for Therapeutic Agents and Drugs of Abuse
In keeping with the recent proliferation of rapid, easy-to-use diagnostic tests, many assays and collection products have entered the marketplace to help clinicians assess dosage appropriateness of therapeutic drugs and to screen for the presence of drugs of abuse. Some of these products require laboratory support while many simple test kits are suitable for point of care use by medical profe...Testing for Human Papillomavirus
