RNA transcripts encoding the 2C-subtype of serotonin (5HT(2C)) receptor undergo up to five adenosine-to-inosine editing events to encode twenty-four protein isoforms. To examine the effects of altered 5HT(2C) editing in vivo, we generated mutant mice solely expressing the fully-edited (VGV) isoform of the receptor. Mutant animals present phenotypic(More)
CONTEXT Reduced energy expenditure following weight loss is thought to contribute to weight gain. However, the effect of dietary composition on energy expenditure during weight-loss maintenance has not been studied. OBJECTIVE To examine the effects of 3 diets differing widely in macronutrient composition and glycemic load on energy expenditure following(More)
Glycine and taurine conjugates of 5beta-cholanic acids have been synthesized using improved procedures based on the peptide coupling reagent, N-ethoxycarbonyl-2-ethoxy-1,2-dihydroquinoline. The conjugates are obtained in chromatographically pure form in yields higher than 90%. The use of this procedure in the large scale preparation of(More)
Supplemental melatonin has been used to treat sleep onset insomnia in children with autism spectrum disorders (ASD), although the mechanism of action is uncertain. We assessed endogenous and supplemental melatonin profiles in relation to sleep in nine children with ASD. In endogenous samples, maximal melatonin concentration (C(max)) and time to peak(More)
PURPOSE This phase I study assessed the maximum tolerated dose (MTD), safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of SJG-136, a sequence-specific DNA cross-linking agent, in patients with advanced cancer. EXPERIMENTAL DESIGN In schedule A, seven patients received escalating doses of SJG-136 (6, 12, 24, and 48 μg/m(2)) daily for(More)
The Phase I enzyme cytochrome p450 1B1 (CYP1B1) has been postulated to play a key role in estrogen-induced mammary carcinogenesis by catalyzing the oxidative metabolism of 17beta-estradiol (E(2)) to catechol estrogens (2-OHE(2) and 4-OHE(2)) and highly reactive estrogen quinones (E(2)-2,3-Q and E(2)-3,4-Q). The potential of the quinones to induce mutagenic(More)
We have designed and constructed a stable isotope ratiometer-multiple ion detector unit, which can drive existing chromatograph-quadrupole or magnetic sector mass gas spectrometers to monitor up to six ions in turn. Each of the three pairs of ions can be selected for quantitation; thus three different or successive components can be analyzed in a single(More)
