Where the fat’s at

In real estate, location is everything. The same might be said of lipids — those crucial cellular fats and oils that serve as building blocks for cells and as key energy sources for the body.

Experts Testify on Much-Improved Troops' Chem-Bio Defense Gear

American troops deployed overseas for the war against Iraq are much better equipped to deal with possible chemical or biological attacks than their Gulf War predecessors, DoD experts said on Capitol Hill today. “I can assure you our war fighters are much better prepared to fight and win in a weapons of mass destruction environment than they were in 1991,” Dr. Dale Klein, assistant to the Secretary of Defense for nuclear, chemical, and biological defense programs, remarked to members of the House Armed Services Terrorism Subcommittee. The U.S. government has warned Iraqi dictator Saddam Hussein and his military commanders not to use chemical, biological or nuclear weapons of mass destruction against U.S. or coalition troops, the Iraqi population, or neighbors in the event of war. If Iraq does deploy WMDs against U.S. or coalition troops, American officials have said that swift and severe retaliation would follow.

Technology, Transformation Improve Battlefield Health Care

Advances in technology and changes in procedures are leading to improved health care for troops before, during and after deployments, U.S. defnse officials say. “An array of medical technologies and capabilities” is being used to provide “layers of protection” to U.S. service members on the modern battlefield, the Defense Department’s top physician said today. Vaccines, protective and detective equipment, and first-rate front-line care combine to ensure American forces are prepared to face any threat, Dr. William Winkenwerder, assistant secretary of defense for health affairs, said in a Pentagon press briefing with several military medical experts.

Common industrial chemical now linked to male infertility

A chemical widely used in industry and present in ground water supplies, has now been found in the semen fluid of infertile men, reports a Queen’s University research scientist. Dr. Poh-Gek Forkert’s study of male mechanics who use trichloroethylene (TCE) in the workplace shows the presence of TCE in their seminal fluid. The team’s findings are reported in the March issue of the international journal, Drug Metabolism and Disposition.

Tapeworm trick could make drugs more effective

To survive and thrive in a decidedly hostile environment, the lowly tapeworm uses a chemical trick to evade the propulsive nature of its intestinal home. Capitalizing on that tapeworm chemistry, scientists at the University of Wisconsin-Madison believe they may have found a way to slow the transit of drugs through the intestine, making them more effective in their delivery and holding out the promise not only of more effective treatment, but also of lowering dosage and cost, and eliminating wasted medicine.
