Mayo Clinic researchers use human antibody to cure malignant melanoma in mice
Mayo Clinic researchers have manipulated a human antibody to induce an anti-tumor response in living mice that consistently curbs -- and often cures -- malignant melanoma, one of the most lethal forms of skin cancer and the most common cancer of young adults.  more

HIV clinician fatalism hinders 'prevention for positives' counseling
UCSF researchers have found that some physicians express a sense of fatalism about HIV prevention and this belief -- that changes in sexual risk behavior by their HIV-positive patients are unlikely -- is hindering the provision of prevention counseling services in publicly-funded clinics. more

Most Americans not sure about the sources of high cholesterol
Results from a recent nationwide survey showed that most respondents did not know that high cholesterol comes from two sources, even though the respondents reported having high cholesterol. When asked about the sources of cholesterol, more than three-quarters of respondents (77 percent) stated incorrectly that the food they eat contributes the most to high cholesterol. In fact, the cholesterol in the bloodstream is not just absorbed from the food people eat, but the majority is produced naturally in the body.  more


Fauci to present research update at World AIDS Conference in Bangkok
At the XV International AIDS Conference in Bangkok, Thailand, Anthony S. Fauci, M.D., director of the National Institute of Allergy and Infectious Diseases (NIAID) and chief of the NIAID Laboratory of Immunoregulation (LIR), will present his laboratory’s latest findings on how aberrant immune activation underlies HIV pathogenesis. He will discuss how viral-induced direct and indirect immune activation has an important impact on the physiologic state of the latent CD4+ T-cell reservoir of HIV. In addition, he will discuss the effects of aberrant immune activation on the phenotype and function of T cells, B cells and natural killer (NK) cells. more

Link established between presence of a key protein and the aggressiveness of prostate cancer
Prostate cancer is much more likely to be aggressive if a key protein called Stat5 is found activated and in abundance in the cancer cells, report researchers from Georgetown University's Lombardi Comprehensive Cancer Center. By inhibiting this protein, called Stat5, doctors are exploring how to develop a new treatment strategy for advanced prostate cancer.  more
