A simple feedback resistor switch keeps latent HIV from awakening
Upon entering a cell, a virus often becomes dormant, turning off its genes and laying low until awakened by som e trigger from its environment. When that trigger is pulled, the virus quickly ramps up production of proteins through built-in positive-feedback loops that turn up gene transcription. view more (2006-12-26)
Pediatric HIV: Oral lesions are commonly associated with the disease
Across the globe, the presence of HIV is wide-spread. At the end of 2004, the United Nations HIV/AIDS program estimated that 2.5 million children under the age of 15 were affected worldwide. view more (2006-10-09)
Widely used hepatitis B drug spurs HIV drug resistance
A Johns Hopkins study has proven false established medical practice that an antiretroviral drug widely used to treat hepatitis B liver infections was safe to use on its own in patients co-infected with HIV. view more (2007-03-01)
How breastfeeding affects HIV transmission
Mother to child transmission of HIV accounts for a large proportion of HIV infections in children, with many infected as a result of breastfeeding, which requires transfer of the virus across mucosal barriers. view more (2005-10-21)
New HIV statistics indicate increasing toll of AIDS on African American community
The country's leading African-American lawmakers, civil rights leaders and medical experts today called on the federal government to adopt and implement a new blueprint to address the HIV/AIDS crisis in the African-American community. view more (2006-11-17)
HIV treatments improve health, but nutritional issues remain
Despite the success of highly active antiretroviral treatment (HAART), people with HIV may still be at higher risk for nutritional deficiencies and abnormalities. view more (2006-12-26)
CHAVI announces international search for genes affecting HIV response
A pioneering collaboration among U.S., European and Australian researchers announced June 20, 2006, will seek to identify genetic differences in the way people respond to HIV. view more (2006-06-20)
HIV Infection Stems From Few Viruses
A new study reveals the genetic identity of human immunodeficiency virus (HIV), the version responsible for sexual transmission, in unprecedented detail. view more (2008-05-16)
Heidelberg Virologists Make HIV Luminate
A working group of virologists headed by Professor Hans-Georg Kr'¤usslich at Heidelberg University Hospitals, jointly with Professor Hanswalter Zentgraf, Division of Applied Tumor Virology of the Deutsches Krebsforschungszentrum (German Cancer Research Center, DKFZ), have been the first to label Human Immunodeficiency Viruses (HIV) for visual... view more...

Causes of global death and disease in the next 25 years
In 1993, the World Bank sponsored the 1990 Global Burden of Disease study carried out by researchers at Harvard University and the World Health Organization (WHO). This study provided the first comprehensive global estimates of death and illness by age, sex, and region. view more (2006-11-28)
AIDS-related cognitive impairment exists in two separate forms
Cognitive impairment in people with AIDS exists in two forms - one mild, another severe - each affecting different areas of the brain. view more (2006-04-06)
Injection of synthetic polymer may improve facial wasting syndrome associated with HIV
Facial injections of polylactic acid, a synthetic biodegradable polymer, may help improve the debilitating facial lipoatrophy (loss of fat in the face) associated with HIV infection and its treatment. view more (2006-03-21)
AIDS study challenges conventional treatment guidelines for HIV patients
A newly published study by investigators at the Center for AIDS Research at Case Medical Center, led by Benigno RodrÃguez, MD, along with a nationwide team of AIDS/HIV experts, strongly challenges conventional thinking about the role of measurements of the amount of HIV particles in the blood as a method of predicting a patient's ability to fight... view more...

Monkeys vaccinated against SIV survive longer after infection
Results of two new studies sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), a component of the National Institutes of Health (NIH), suggest that even if an HIV vaccine offers imperfect protection against the virus, it might provide vaccinated individuals with an important benefit: a significant survival advantage... view more...

The Role Of Sexually Transmitted Diseases, Malaria, And Tuberculosis On The Hiv-1/Aids Epidemic In Africa (p 2177)
The effect of HIV-1 on other infectious diseases in Africa is an increasing public health concern. In a review in this week's issue of THE LANCET, Elizabeth Corbett from the London School of Hygiene and Tropical Medicine, UK, and the Harare Biomedical Research and Training Institute, Zimbabwe, and colleagues describe the role that three major... view more...

Imitating monkey's 'jumping genes' could lead to new treatments for HIV
UCL (University College London) scientists have taken a significant step in understanding how retroviruses such as HIV can move between species and the biological mechanisms behind the 'jumping genes' which make some monkeys immune. They will now use this knowledge to develop a gene therapy treatment for HIV/AIDS in humans. view more (2008-02-19)
Body's anti-HIV drug explained
Humans have a built-in weapon against HIV, but until recently no one knew how to unlock its potential. view more (2008-10-13)
Researchers discover new battleground for viruses and immune cells
Vaccines have led to many of the world's greatest public health triumphs, but many deadly viruses, such as HIV, still elude the best efforts of scientists to develop effective vaccines against them. view more (2008-02-07)
STDs disrupt genetic bottleneck that usually constrains HIV infection
Scientists have shown that HIV faces a genetic "bottleneck" when the virus is transmitted heterosexually from one person to another, by way of the genital mucosa. view more (2009-01-23)
Adolescent condom use with 'casual' versus 'main' partners
This week, a new study from researchers at the Bradley Hasbro Children's Research Center and Brown Medical School, finds that teen attitudes toward condom use with whom they perceive as casual sexual partners versus main partners is crucial in developing effective HIV intervention programs. view more (2006-08-23)
