MCG researcher among first to receive NIH stimulus funding

... NeSmith says. Some drugs used to treat cocaine addiction have adverse effects on the kidneys, so it's important to know if a patient suffers from asymptomatic renal disease. If that's the case, alternative drug doses or treatments could be used. The study also will examine the relationship between ...

Early administration of antiretroviral therapy can improve survival

... for establishing a guideline cutoff point. Current clinical guides recommend waiting for the CD4 count to fall below 350 cells per milliliter (L) in asymptomatic patients.

Anti-herpes treatment reduces HIV levels in women infected with both viruses

... and, in addition, reduces the quantity of HIV in the plasma. As expected, there was also dramatic reduction in the detection of symptomatic and asymptomatic presence of HSV-2. The effects appeared to gradually increase over the 3 month follow-up period, with no sign of abating.' These results indicate a ...

Bad blood between boys and girls

... and colleagues analysed the effect of latent (or dormant) toxoplasmosis on the probability of the birth of a boy in humans. Latent toxoplasmosis is asymptomatic but is usually a life-long infection characterised by the presence of anti-Toxoplasma antibodies in the blood. They analysed over 1800 clinical ...

Effective HIV control may depend on viral protein targeted by immune cells

... In people receiving no antiretroviral treatment, the improved HIV control associated with Gag-specific CD8 response would probably translate into asymptomatic infection for more than a decade, compared with progression to AIDS within two to three years of infection in those with no Gag responses. The ...

Viral marker of human migration suspect

... or JCV, is a small double-stranded DNA virus that is thought to be primarily transmitted from parents to their children. Infection is usually asymptomatic unless a person has a weak immune system, in which case the virus can cause neurological disease. There are more than 14 subtypes of the virus, ...

HIV-1's high virulence might be an accident of evolution

... can exhaust the immune system," he said. "If you could somehow dampen the response, it might effectively convert the condition to the more chronic, asymptomatic infection seen in monkeys." Further studies by the team will examine whether SIVs carrying Nef genes artificially made incapable of limiting T ...

New results validating Pall prion reduction filter disclosed at ISBT Congress

... that they could have caught the disease through infected blood. In the U.S., a second cow just tested positive for BSE. "Considering the lengthy, asymptomatic incubation period of vCJD in people, no one can accurately determine the magnitude of the next wave of an outbreak. Nor do we know how many people ...

Forsyth scientists find three bacteria associated with oral cancer

... are not diagnosed until their oral cancer is in its advanced stages," Mager said. In part, that is because, in its early stages, oral cancer may be asymptomatic or mimic benign conditions, so those who have it do not seek dental or medical care. "A saliva test would be an easy, non-invasive way to diagnose or ...

Boosting HIV screening can increase survival and is cost effective

... return on investment. "HIV is a severe disease that, left untreated, produces substantial morbidity and mortality," said Paltiel. "It has a long asymptomatic phase, which can be diagnosed using very effective, inexpensive tests. Most importantly, early detection speeds linkage to proven, life-prolonging ...
