HIV virus may hide in brain HealthDay News via Bloomberg Businessweek Share ![]() ![]() ![]() ![]() The brain can be a convenient hiding place for HIV, the virus that causes AIDS. That's the finding of Swedish researchers who analyzed samples from about 70 HIV-infected patients who'd been taking anti-HIV drugs. The tests showed that about 10 percent of the patients — a larger proportion than expected — had traces of HIV in their spinal fluid but not in their blood. More
Limit fingerstick devices to just 1 patient, FDA and CDC say Medscape Medical News Share ![]() ![]() ![]() ![]() In the war against the transmission of bloodborne pathogens such as hepatitis B virus, the U.S. Centers for Disease Control and Prevention and the U.S. Food and Drug Administration recommended that fingerstick devices should never be used with more than one person. They issued similar guidance for point-of-care (POC) blood-testing devices such as glucometers and instruments for insulin administration. The two federal agencies said the shared used of blood lancing and POC testing devices has led to a steady rise in reports of bloodborne-pathogen infections — mostly involving hepatitis B virus — during the past 10 to 15 years. More Company recalls ground beef after E. coli reports CNN Share ![]() ![]() ![]() ![]() Cargill Meat Solutions Corp. has recalled about 8,500 pounds of ground beef that may be contaminated with E. coli, the U.S. Department of Agriculture announced. The move came after three people, two in Maine and one in New York, were identified as becoming ill from a strain of E. coli, the government said. More
Anti-JCV antibody ELISA could help determine PML risk Medscape Medical News Share ![]() ![]() ![]() ![]() Researchers from Biogen Idec Inc and Elan Corporation Inc say they have developed an enzyme-linked immunosorbent assay (ELISA) that can detect JC virus antibodies in serum and plasma. They hope that with further research the assay could be used to identify patients with multiple sclerosis at greatest risk of developing progressive multifocal leukoencephalopathy (PML) associated with natalizumab treatment and help guide use of this immunosuppressive agent. More Scientists create liver cells from patients' skin Reuters Share ![]() ![]() ![]() ![]() Scientists have created liver cells in a lab for the first time using reprogrammed cells from human skin, paving the way for the potential development of new treatments for liver diseases that kill thousands each year. Cambridge University scientists who reported their results in the Journal of Clinical Investigation, said they also found a way of avoiding the kind of intense political and ethical rows over embryonic stem cells which are currently hampering work in the United States.

The trials of testosterone testing Clinical Laboratory News Share ![]() ![]() ![]() ![]() Are there times when a test is so unreliable and imprecise that it simply shouldn't be used with certain patients? That's the debate swirling around total testosterone assays — direct immunoassays in particular—when used for testing in women and children. Concentrations of this steroid hormone may be as low as 0.17 nmol/L for these populations, compared with 11.1 nmol/L, the lower range of normal in men. A growing body of evidence has clearly demonstrated that the performance of some immunoassays at such low concentrations is sub-par at best, prompting experts to question their use in women and children. More Macrophages: The 'defense' cells that help throughout the body Science Daily Share ![]() ![]() ![]() ![]() The term "macrophage" conjures images of a hungry white blood cell gobbling invading bacteria. However, macrophages do much more than that: Not only do they act as antimicrobial warriors, they also play critical roles in immune regulation and wound — healing. They can respond to a variety of cellular signals and change their physiology in response to local cues. More |
