BACKGROUND NRTI-sparing regimens may avoid long-term mitochondrial, bone and renal toxicities and maintain viral suppression. METHODS In the RADAR study, 85 antiretroviral-naïve HIV-infected patients were randomized to receive either raltegravir (RAL) (n = 42) or tenofovir/emtricitabine (TDF/FTC) (n = 43), each with ritonavir-boosted darunavir (DRV/r).(More)
OBJECTIVE Both HIV and hepatitis C virus (HCV) infections are associated with higher osteoporotic fracture risk. Increased bone turnover, liver fibrosis, tenofovir (TDF) use or hormonal imbalances are possible underlying mechanisms. DESIGN This prospective, cross-sectional study assessed 298 male volunteers with either virologically suppressed HIV or(More)
This report shows the results of a large-scale laparoscopic intrauterine insemination program on a flock of Australian Merino sheep in Argentine Patagonia. The study was carried out on a total of 1824 ewes (3-to-7-yr-old) and 480 ewe hoggets (19-20 months old) on 2 farms in the southeastern region of Santa Cruz Province, in April and May 1996.

The purpose of this study was to determine the clinical accuracy of 82Rb PET/CT myocardial perfusion imaging (MPI) when performed with regadenoson stress in a U.S. Department of Veterans Affairs (VA) population of patients. Methods: The initial cohort of 480 patients undergoing vasodilator PET MPI with regadenoson stress at our institution from September(More)
Background HIV/HCV co-infected subjects have a significantly greater osteoporotic fracture risk than HIV-infected, despite the fact that HIV/HCV co-infection has not been associated with lower bone mineral density (BMD) than HIV or HCV alone. We evaluated if changes in bone microarchitecture , measured by trabecular bone score (TBS) could explain these(More)
