A population-based pharmacokinetic (PK) model has been developed for efavirenz based on 16 phase I studies. The combined data set consisted of 334 healthy volunteers, 2,907 efavirenz dose administrations and 9,342 measured plasma concentrations across a range of doses from 100-600 mg. The pharmacokinetic structural model was a 2-compartment model with(More)
Data describing the pharmacokinetics and pharmacodynamics of low dose aspirin (acetylsalicylic acid; ASA) are limited. This single-center study was designed to determine the rate and extent of oral absorption of 80-mg ASA tablets in healthy, young male subjects and to assess the intra- and inter-subject variability of ASA pharmacokinetics and platelet(More)
A distributed sensing/fusion network consists of more than one (spatially) separated sensors, each with possibly different characteristics and not all of them sensing the same environment. Due to their vast applicability, there has been a flurry of recent activity in the area of network design with respect to distributed sensing/fusion. Issues involved in(More)
Losoxantrone is an anthrapyrazole derivative in Phase III development in the U.S. for solid tumors, notably breast cancer. To obtain information on the routes of elimination of the drug, a study was conducted in four patients with advanced solid tumors, which involved intravenous administration of 100 microCi of [14C]losoxantrone for a total dose of 50(More)
OBJECTIVES Although total knee replacement (TKR) is cost effective and successful in most cases, patient-reported outcome measures demonstrate 20% of people remain unsatisfied at 1 year after a technically successful procedure. Our group has previously shown that patients with severe knee osteoarthritis (OA) awaiting surgery can achieve a short-term(More)
A semi-automated imaging system is described to quantitate estrogen and progesterone receptor immunoreactivity in human breast cancer. The system works for any conventional method of image acquisition using microscopic slides that have been processed for immunohistochemical analysis of the estrogen receptor and progesterone receptor. Estrogen receptor and(More)
BACKGROUND This study was designed to quantify the effects of penetration enhancers on systemic bioavailability of 0.3% meloxicam (MLX) hydroxypropylcellulose gels. Cutaneous microdialysis was also performed to assess dermis availability and to better understand the penetration process. The gels tested were a 1% oleic acid gel, a 5% menthol gel, and a(More)
PURPOSE The purpose of these investigations was to develop an improved method for measuring precorneal residence time (RT) and to demonstrate its efficacy with novel formulations. METHODS A biomicroscope was adapted for use as a clinical fluorometer. Using a nonpenetrating fluorescent probe (FITC-dextran, 70,000-73,000 molecular weight [MW]), RT was(More)
A high-performance liquid chromatographic (HPLC) method using fluorescence detection has been developed for the simultaneous analysis of low nanogram concentrations of an anti-inflammatory drug, 5-Bromo-2-(4-fluorophenyl)-3-[4-(methylsulfonyl)phenyl]thiophene (DuP 697), and a potential metabolite (X6882) in human plasma and of DuP 697 in human urine. This(More)
Cancer chemotherapy frequently requires long periods of multiple intravenous infusions that often results in patients opting out of treatment. The main purpose of this study was to investigate the feasibility of delivering one of these anticancer agents: etoposide phosphate (ETP) transdermally using iontophoresis and a combination of(More)
