BACKGROUND Antiretroviral chemoprophylaxis before exposure is a promising approach for the prevention of human immunodeficiency virus (HIV) acquisition. METHODS We randomly assigned 2499 HIV-seronegative men or transgender women who have sex with men to receive a combination of two oral antiretroviral drugs, emtricitabine and tenofovir disoproxil fumarate (FTC-TDF), or placebo once daily. All...
BACKGROUND The effect of nonthymidine nucleoside reverse-transcriptase inhibitors (NRTIs) on fat mitochondrial DNA (mtDNA) content and function is unclear. METHODS A5202 randomized antiretroviral therapy-naive human immunodeficiency virus-infected subjects to abacavir-lamivudine (ABC/3TC) versus tenofovir DF-emtricitabine (TDF/FTC) with efavirenz (EFV) or atazanavir-ritonavir (ATV/r). A5224s,...
To assess the safety and efficacy of rilpivirine in combination with emtricitabine and tenofovir (RPV/FTC/TDF) as a once-daily single-tablet regimen (STR) in HIV-1-infected children and adolescents we performed a multicenter case series study of HIV-1-infected patients. Inclusion criteria were initiation of therapy with RPV/FTC/TDF before the age of 18. Patients were divided into undetectable v...
Antiretroviral preexposure prophylaxis (PrEP) for persons at high risk of human immunodeficiency virus infection is a promising new prevention strategy. Six randomized trials of oral PrEP were recently conducted and demonstrated efficacy estimates ranging from 75% to no effect, with nonadherence likely resulting in attenuated estimates of the protective effect of PrEP. In 1 of these trials, the...
OBJECTIVES To examine reasons behind the failure of the Federal Trade Commission (FTC) to preserve puff count information from standard cigarette testing and to elucidate the importance of puff count to overall tar yields. METHODS We reviewed industry documents on origins of the FTC test and datasets provided by the Tobacco Institute Testing Laboratory to the tobacco industry and FTC for repo...
This paper investigates to what extent fair trade programmes, are indeed ‘fair’. This is accomplished by comparing fair trade with free trade and protectionist trade regimes on their compliance of the criteria set by the fair trade movement itself. This comparison is made using comparative cost based and economies of scale models. It is found that whether or not fair trade is superior to free t...
BACKGROUND & AIMS We compared treatments for patients with chronic hepatitis B virus (HBV) infection who had an incomplete response to adefovir dipivoxil (ADV). We evaluated a combination of fixed-dose emtricitabine (FTC) and tenofovir disoproxil fumarate (TDF) from the start (early combination) versus TDF as monotherapy. METHODS Patients (n = 105) were randomly assigned to groups given TDF (...
BACKGROUND Anaplastic thyroid cancer is considered to be one of the most aggressive human malignancies, and the mean survival time after diagnosis is approximately six months, regardless of treatments. This study aimed to examine how EpCAM and its related molecules are involved in the characteristics of anaplastic thyroid carcinoma. METHODOLOGY/PRINCIPAL FINDINGS Two differentiated thyroid ca...
Background. Existing data on anthropomorphic changes in resource-limited settings primarily come from observational or cross-sectional studies. Data from randomized clinical trials are needed to inform treatment decisions in these areas of the world. Methods. The AIDS Clinical Trials Group Prospective Evaluation of Antiretrovirals in Resource-Limited Settings (PEARLS) study was a prospective,...
This paper aims to resolve the three major issues of fault tolerant control (FTC) for robot manipulators: (i) faster response, lower tracking errors, chattering and higher robustness FTC, (ii) requirement partial or full knowledge dynamics design model-based (iii) global fixed-time convergence system. First, a controller based on backstepping is designed its disadvantages are analysed. Then, an...
