Background: Stavudine-containing regimens are associated with a potential for lipoatrophy and dyslipidemia. We assessed the safety and efficacy of reducing the dose of stavudine compared to switching to tenofovir or maintaining the standard dose of stavudine.
Methods: Clinically stable lipoatrophic HIV-infected patients receiving antiretroviral therapy containing stavudine 40 mg bid with a plasma HIV RNA <200 copies/mL for at least 6 months were randomized to maintain stavudine 40 mg bid (d4T40 arm), to reduce to 30 mg bid (d4T30 arm), or to switch from stavudine to tenofovir-DF (TDF arm) while preserving the remaining drugs. Fasting metabolic parameters were assessed at baseline and at weeks 4, 12, and 24. Mitochondrial parameters in peripheral blood mononuclear cells and body composition were measured at baseline and at week 24.

For years, the number of performed CT examinations has been rising. At the same time, computed tomography became more dose efficient. The aim of this article is to give an overview about the state ...
The aim of this study was to evaluate the suitability of size specific dose estimates (SSDE) to estimate patient dose in Fast kVp switching dual energy CT. An anthropomorphic phantom (RAN-110) was rep...

The dose amount of poisonous or toxic substance or dose of ionizing radiation required to kill 50% of the tested population.
Gene rearrangement of the B-lymphocyte which results in a substitution in the type of heavy-chain constant region that is expressed. This allows the effector response to change while the antigen binding specificity (variable region) remains the same. The majority of class switching occurs by a DNA recombination event but it also can take place at the level of RNA processing.
A treatment schedule in which the total dose of radiation is divided into large doses.
The highest dose of a biologically active agent given during a chronic study that will not reduce longevity from effects other than carcinogenicity. (from Lewis Dictionary of Toxicology, 1st ed)
Administration of the total dose of radiation (RADIATION DOSAGE) in parts, at timed intervals.
