Resistance remains a problem in treatment failure [PDF]

Journal of the International AIDS Society, 2014
IntroductionProven resistance against HIV drugs, either by phenotyping or genotyping is a rare event in clinical trials. The overall assumption of drug resistance disappearing is additionally driven by the recommendations to screen for transmitted drug resistance, leading to large numbers of examinations with relatively low rates of resistance. Goal of

Role of HIV infection duration and CD4 cell level at initiation of combination anti-retroviral therapy on risk of failure.

PLoS ONE, 2013
BackgroundThe development of HIV drug resistance and subsequent virological failure are often cited as potential disadvantages of early cART initiation.

Polyurethane spray coating of aluminum wire bonds to prevent corrosion and suppress resonant oscillations

, 2015
Unencapsulated aluminum wedge wire bonds are common in particle physics pixel and strip detectors. Industry-favored bulk encapsulation is eschewed due to the range of operating temperatures and radiation.

Therapeutic Efficacy of Sulfadoxine-Pyrimethamine and Prevalence of Resistance Markers in Tanzania Prior to Revision of Malaria Treatment Policy: Plasmodium Falciparum Dihydrofolate Reductase and Dihydropteroate Synthase Mutations in Monitoring in Vivo Resistance. [PDF]

, 2004
Prior to the 2001 malarial treatment policy change in Tanzania, we conducted trials to assess the efficacy of sulfadoxine-pyrimethamine (SP) and the usefulness of molecular markers in monitoring resistance.

Prevalence and determinants of virological failure, genetic diversity and drug resistance among people living with HIV in a minority area in China: a population-based study

BMC Infectious Diseases, 2020
Background Liangshan Yi Autonomous Prefecture is one of the areas that most severely affected by human immunodeficiency virus (HIV) in China, and virological failure on antiretroviral therapy (ART) is serious in this area.

Modeling long-term longitudinal HIV dynamics with application to an AIDS clinical study

, 2009
A virologic marker, the number of HIV RNA copies or viral load, is currently used to evaluate antiretroviral (ARV) therapies in AIDS clinical trials. This marker can be used to assess the ARV potency of therapies, but is easily affected by drug exposures,
