Researchers uncover attack mechanism of illness-inducing bacterium found in shellfish

An infectious ocean-dwelling bacterium found in oysters and other shellfish kills its host's cells by causing them to burst, providing the invader with a nutrient-rich meal, researchers at UT Southwestern Medical Center have found.

Alternative vaccine strategy shows promise in prostate cancer patients

New research indicates that giving patients a continuous low dose of an immune system booster, a method known as metronomic dosing, as part of a therapeutic prostate cancer vaccine strategy is safe and produces similar immune responses and fewer side effects than the more common dosing method, which is not well tolerated by many patients. This study, led by researchers at that National Cancer Institute (NCI), part of the National Institutes of Health, was published in the Aug. 15, 2008, issue of Clinical Cancer Research.

NanoBio vaccine for hepatitis B shows promise

Chronic hepatitis B infects 400 million people worldwide, many of them children. Even with three effective vaccines available, hepatitis B remains a stubborn, unrelenting health problem, especially in Africa and other developing areas. The disease and its complications cause an estimated 1 million deaths globally each year.

Rare case explains why some infected with HIV remain symptom free without antiretroviral drugs

AIDS experts at Johns Hopkins say they have compelling evidence that some people with HIV who for years and even decades show extremely low levels of the virus in their blood never progress to full-blown AIDS and remain symptom free even without treatment, probably do so because of the strength of their immune systems, not any defects in the strain of HIV that infected them in the first place.

In-depth review of current research on the health effects of vitamin D

Despite considerable progress in research to understand the health effects of vitamin D, experts convened by the NIH to review the available data found major gaps in the evidence. The data are strongest in the area of bone health among elderly men and post-menopausal women, suggesting that increased vitamin D intake can improve bone health and prevent falls. For other age groups and health issues, though, it is too early to say conclusively whether more vitamin D might be beneficial.

NanoViricides reports HIVCide-I significantly superior to current anti-HIV three drug cocktail standard

NanoViricides, Inc. said that additional biological tests and data analysis have shown that animals treated with its lead anti-HIV drug candidate, HIVCide-I, demonstrated a substantially greater reduction in viral load -- number of infectious virus particles per milliliter of blood -- when compared to the animals given the anti-HIV "combo cocktail" in a preliminary animal study. An important objective of anti-HIV treatment is to minimize the viral load.

Early treatment key to combating hepatitis C virus

Canadian researchers have shown that patients who receive early treatment for Hepatitis C virus (HCV) within the first months following an infection, develop a rapid poly-functional immune response against HCV similar to when infection is erradicted spontaneously, according to a new study published in the Journal of Virology.

RNAi used to dramatically suppress HIV infection in an organism

Hopes languished last September when a promising candidate HIV vaccine failed to work. Despite this setback, many researchers still believe immunization is possible, and a new study suggests they're correct-at least at the cellular level.
