New evidence shows that drug-resistant virus passed from mother-to-child can quickly establish itself in infants? CD4+ T cells where it can hide for years, likely limiting their options for future treatment. The study is published in the May 15 issue of The Journal of Infectious Diseases, now available online.
Dr Deborah Lehmann, who leads infectious diseases research at the Telethon Institute for Child Health Research, said the findings show that infection is an increasing concern in affluent countries.
The National Institutes of Health estimates that eight out of ten people will suffer from back pain, making it one of the most common medical problems today. The good news is that you can treat it, minimize it, and even prevent it by following some back-friendly guidelines.
An interactive “supermap” that portrays the mutations and spread of the avian flu around the globe over time should help researchers and policy makers better understand the virus and anticipate further outbreaks, according to a new study involving University of Colorado at Boulder and Ohio State University researchers.
The ability of HIV-1 to develop high levels of genetic diversity and acquire mutations to escape immune pressures contributes to our difficulties in producing a vaccine. David Nickle et al present here an efficient algorithm to develop vaccines that cope with the diversity of HIV or other variable pathogens.
A Medical College of Wisconsin and Children?s Research Institute team in Milwaukee has created a free, searchable genetic database that will significantly improve diagnostic testing and genetic tracking of human and animal influenza viruses. The site, which is automatically updated weekly, will also facilitate rapid response as new virus strains emerge to cause either annual epidemics or the next pandemic.
It has long been known that UV light can damage DNA, reducing its ability to replicate and interact with proteins, and often resulting in the development of skin cancers. However, not much is known about how the elasticity of DNA strands is altered upon exposure to UV light.
Bird flu patients who get early treatment with the antiviral drug Tamiflu have the best chances of surviving while using steroids can do more harm than good, the World Health Organization (WHO) said.
Some HIV-infected patients in Uganda who self paid for their antiretroviral medications experienced interruptions in drug supply due to either financial demands or supply logistical disruptions. These treatment interruptions led to the development of resistance to antiretroviral medications in patients.
A new study has pinpointed a natural ingredient of human blood that effectively blocks HIV-1, the virus predominantly responsible for human AIDS, from infecting immune cells and multiplying.
