[(18)F]MK-9470 is a selective, high-affinity, inverse agonist (human IC(50), 0.7 nM) for the cannabinoid CB1 receptor (CB1R) that has been developed for use in human brain imaging. Autoradiographic studies in rhesus monkey brain showed that [(18)F]MK-9470 binding is aligned with the reported distribution of CB1 receptors with high specific binding in the(More)
BACKGROUND Observational data and non-human primate challenge studies suggest that cell-mediated immune responses might provide control of HIV replication. The Step Study directly assessed the efficacy of a cell-mediated immunity vaccine to protect against HIV-1 infection or change in early plasma HIV-1 levels. METHODS We undertook a double-blind, phase(More)
Adipocyte complement-related protein of 30 kDa (Acrp30, adiponectin, or AdipoQ) is a fat-derived secreted protein that circulates in plasma. Adipose tissue expression of Acrp30 is lower in insulin-resistant states and it is implicated in the regulation of in vivo insulin sensitivity. Here we have characterized the ability of PPARgamma agonists to modulate(More)
OBJECTIVES To evaluate the clinical efficacy and tolerability of etoricoxib in the treatment of osteoarthritis (OA) of the knee and define the clinically active dose range for further clinical trials. METHODS This two-part, randomized, double-blind, placebo- and active comparator-controlled trial was conducted in 617 adults with knee OA. In Part 1 (6(More)
RATIONALE Histamine and dopamine contribute to the maintenance of wakefulness. OBJECTIVE This study aims to conduct an exploratory analysis of the effects of 10 and 50 mg of MK-0249, a novel histamine subtype-3 receptor inverse agonist, and 200 mg of modafinil, a presumed dopaminergic compound, on EEG power spectra during sleep deprivation and subsequent(More)
Sudden intense sensory stimuli elicit a cascade of involuntary responses, including a short-latency skeletal muscular response ('eyeblink startle response') and longer-latency autonomic responses. These responses are enhanced when subjects anticipate an aversive event compared to periods when subjects are resting ('fear potentiation'). It has been reported(More)
The murine 4F2 molecule is a 125 kilodalton disulfide-linked heterodimeric cell-surface glycoprotein which has been shown to be involved in the processes of cellular activation and proliferation (1). To elucidate the structure, expression, and regulation of the 4F2 molecule, a murine 4F2 heavy chain (4F2HC) cDNA has been isolated and structurally(More)
PURPOSE This phase I study, conducted in advanced-stage cancer patients, assessed the safety and tolerability of oral vorinostat (suberoylanilide hydroxamic acid), single-dose and multiple-dose pharmacokinetics of vorinostat, and the effect of a high-fat meal on vorinostat pharmacokinetics. EXPERIMENTAL DESIGN Patients (n = 23) received single doses of(More)
BACKGROUND The inhibition of cholesteryl ester transfer protein (CETP) is considered a potential new mechanism for treatment of dyslipidaemia. Anacetrapib (MK-0859) is a CETP inhibitor currently under development. We aimed to assess anacetrapib's effects as monotherapy on low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol(More)
The metabolism and excretion of [(14)C]sitagliptin, an orally active, potent and selective dipeptidyl peptidase 4 inhibitor, were investigated in humans after a single oral dose of 83 mg/193 muCi. Urine, feces, and plasma were collected at regular intervals for up to 7 days. The primary route of excretion of radioactivity was via the kidneys, with a mean(More)
