New study shows benefit of early therapy in HIV-infected infants

...tive Study developed a way to standardize CD4 cell counts in relation to age, and thus better evaluate immune status. They call this age-adjusted CD4 cell count the "z-score." Based on data collected over the past 20 years on infected children born to HIV-1 infected women, the investigators concluded that ...

Leave it to salmon to leave no stone unturned

...lmon through the UW's Alaska Salmon Program. Using counts of spawning sockeye for the last 50 years and previously measured nest sizes, Moore calculates that every summer the sockeye disturb at least 30 percent of the stream beds of two Alaskan streams he studied. And in years when salmon populations are h...

How can we protect patients with weakened immune systems from influenza?

Access to antiretrovirals unlikely to reduce HIV infection rates

...stic laboratories that could routinely measure CD4 counts and viral loads of HIV-infected individuals (only if this is done could people be treated before they develop overt symptoms). They also took into account different ways that people might change their sexual behavior if they get treatment (which migh...

Cholesterol gets 'thumbs up' for role in digit development

When a new mother counts her newborn's fingers and toes, she probably doesn't realize that cholesterol may be to thank for baby's complete set of 20 digits. Although cholesterol has a bad rap as the sticky, fatty substance responsible for clogging arteries, Vanderbilt Univ...

Flesh-eating bacteria escape body's safety net

Nizet explained that the researchers' findings could lead to novel treatments for Strep-related diseases. "Instead of attempting to kil...

Study shows AIDS drugs cost-effective, care underfunded

...s who were sicker ?that is, who had lower CD4 cell counts ?as for healthier patients with higher CD4 cell counts. But the sicker patients ran up much higher bills for other care: Expenditures were almost six times greater for hospitalizations, and almost eight times greater for non-HAART medications, for th...

Compound from marine bacteria shows potential as multiple myeloma therapy

... in some myeloma patients, including altered blood counts and nerve pain. In some patients, the disease can be resistant or become resistant to bortezomib. Because NPI-0052 and bortezomib attack the same intracellular target in different ways, the Dana-Farber researchers contend that combining these two ag...

A new step towards an AIDS vaccine

...1 and correlates with high viral load, reduced CD4 counts and susceptibility to opportunistic infections, and is only partially reverted by anti-retroviral therapy. By identifying the active component of HIV-1 which stimulates pDC function, and consequently other antigen presenting cell function, the author...

Zinc supplements safe for HIV-infected children

...on, HIV-1 RNA in plasma and CD4+ T lymphocyte cell counts were measured one month before the study, at the first study visit and three, six and nine months after the start of supplementation. The study authors found no increase in plasma HIV-1 viral load measurements in the children receiving zinc, meaning...

In the future, Dr. Krishnamoorthy looks toward the potential use of stem cells for this purpose, and also the development of better immunosuppressive medications to keep the body from rejecting the transpla...

Forsyth scientists find three bacteria associated with oral cancer

...SCC. And, in fact, we found that elevated salivary counts of the three bacteria correctly identified 80% of individuals with oral cancer and 83% of controls." If their findings are replicated in future studies, the Forsyth team envisions a simple saliva test that could be administered by dental technicians...

Once you get new blood, those defects disappear from the population. Hybrids are better than inbred animals." The paper also no...

Space matters: Estimating species diversity in the fossil record

Of the 5,417 volunteers who were enrolled, 368 became infected during the study. The vaccine was found not to be effective in preventing HIV infection; infection rates amon...

Results from this study are even more promising than results using Bexxar after other therapies have failed. In those studies, 70 percent of patients responded to Bexxar an...
