CONTEXT It is unclear whether delay in initiation of antiretroviral therapy (ART) may lead to a poorer viral load response for patients with human immunodeficiency virus (HIV). OBJECTIVE To characterize the relationship of viral load response to ART with baseline CD4 cell count and baseline viral load. DESIGN Inception cohort of 3430 therapy-naive patients with HIV, of whom 3226 patients ha...

Seminal viral load is likely to be directly related to the sexual transmissibility of human immunodeficiency virus type 1 (HIV-1). However, it is not clear whether the level of HIV-1 in semen varies with the stage of infection and whether antiretroviral therapy reduces seminal viral load. A nucleic acid sequence-based amplification (NASBA) technique was used to quantify HIV-1 RNA as an indicato...

Plasma viral burden has proven valuable in predicting the future course of systemic HIV related disease and the response to treatment. It is not known whether plasma or cerebrospinal fluid (CSF) viral burden can be used to predict onset of or response to treatment of nervous system disease. We propose a model of viral load mediated neurotoxicity underlying peripheral and central HIV associated ...

Viral load quantification is the amount of particular viral DNA or RNA in a blood samples. It is one of the surrogate biomarker of AIDS. High viral load indicates that the immune system is failed to fight against viruses. The aim of this study was to evaluate the impact of biofield treatment on HIV-1 and HCMV in terms of viral loads as surrogate marker. The viral load assay was performed on sto...

The extent to which different locomotor tasks require cognitive control is not well characterized. In this article, the authors consider the potential increase in attentional demands associated with carrying an anterior load while clearing an obstacle. Nine healthy male volunteers participated in 80 walking trials, 20 in each of 4 conditions: 1 no load condition (NL) and 3 carrying conditions (...

Antiretroviral (ARV) medication for substance users has been a controversial issue with respect to whether current substance users can successfully maintain their medication regimens. This study compared ARV adherence across current substance users, former substance users and those with no history or current use and the relative impact of a medication adherence intervention on all three groups....

To investigate the role of viral load in the pathogenesis of hemorrhagic fever with renal syndrome, the Hantaan virus RNA load in plasma from 101 patients was quantified, and the relationships between viral load and disease course, severity, and level of specific humoral immunity were analyzed. The viral load, detectable in 79 patients, ranged from 3.43 to 7.33 log10 copies/mL of plasma. In the ...

The critical load (CL) of acidic atmospheric deposition represents the load of acidity deposited from the atmosphere to the earth's surface at which harmful acidification effects on sensitive biological receptors are thought to occur. In this study, the CL for forest soils was estimated for 27 watersheds throughout the United States using a steady-state mass balance approach based on both natio...

We examined whether higher human papillomavirus type 16 (HPV16) viral load predicted risk of cervical intraepithelial neoplasia 3 (CIN3) or cancer (together termed > or =CIN3) within a cohort of 20,810 women followed for 10 years with cytologic screening. Semiquantitative viral load for HPV16 was measured on baseline cervicovaginal specimens using a type-specific hybridization probe test with s...
