...o the development of protease inhibitors, the powerful drugs that revolutionized the treatment of HIV/AIDS; pioneering research that led to the use of azt to block mother-to-child transmission of HIV, resulting in the virtual elimination of this form of HIV transmission in the industrialized world; and s...

HIV Eradication Unlikely Following Bone Marrow Transplantation

...gested that utilising more potent anti-HIV drugs alongside pre-transplant chemo- or radiation therapy might provide a more satisfactory outcome, since azt monotherapy had been used in most cases (Huzicka 1999). Since then, however, other less toxic and/or invasive methods of HIV eradication have b...

Individu...ad and similarly, there was a lack of correlation between concentrations of azt and 3TC and plasma/milk viral loads. In 10% of cases, NVP drug concen...

Health-Care Workers Exposed to HIV on Job Need Preventive Treatment

...s, found that the odds of becoming infected with HIV were reduced by about 81 percent among those who took zidovudine — an anti-HIV drug also known as azt or Retrovir — after exposure. The study also reported that the odds of HIV infection were higher if a health-care worker had a deep injury, if there w...

Molecular Mechanism Of HIV Infecting The Healthy Cells Discovered.

... attack the virus. Protease process viral proteins and plays an important role in the making of infectious virus. There are various drugs like azt and other combination drugs to inhibit Reverse Transcriptase and Protease proteins but no single drug to act on Integrase. Fluorescence Resonance...

...ailable in US market due to strict patent laws, so the people can use only branded Zidovudine drugs, as branded drugs are very costly, treatment using azt has been very costly in the US. Due to expiry of the patents in the US for Zidovudine, now generic drugs can be sold and brought in US, though generic...

Drugs to stop burgeon of HIV

...are eaten up by macrophages," he explained. At present there are two types of anti-HIV drugs available – reverse transcriptase inhibitors such as azt and protease inhibitors. These work by targeting the reproduction of the virus within the host cell."The problem is HIV can mutate to escape the drugs...

Computational model simulates AZT metabolism in mitochondria

Researchers at the Virginia Bioinformatics Institute (VBI) at Virginia Tech have developed a computational model that allows scientists to better understand the metabolism and toxicity of the HIV/AIDS drug zidovudine (azidothymidine, AZT). AZT is used successfully as part of Highly Active Anti-...

Feline virus, antiviral drug studied to understand drug resistance

...phetamine. We know how long it normally takes the mutation to appear in the virus. We predict that it will appear earlier in cells exposed to both azt and methamphetamine, he said. Mathes said that the first year of the project is focused on continued in vitro studies using both FIV and cat cell ...

SLU researchers uncover direct evidence on how HIV invades healthy cells

...g it a permanent part of the cell. The third protein, protease, processes viral proteins and is essential to make infectious virus. Drugs such as azt and drug combinations (cocktails) exist to inhibit reverse transcriptase and protease. As of yet, there are no drugs to counter integrase. By using...

Hepatitis C responds best to combo of ribavirin and interferon, study concludes
