Sprague-Dawley rats were used to evaluate a model system for studying the hepatotoxicity caused by microcystin-LR (MCYST-LR), a toxin produced by the cyanobacterium (blue-green alga) Microcystis aeruginosa, and for evaluating the in vivo therapeutic potential of cholestyramine resin (CTR) which was found to bind the toxin in vitro. Female rats were treated(More)
Reduction rules in Interaction Nets are constrained to pattern match exactly one argument at a time. Consequently, a programmer has to introduce auxiliary rules to perform more sophisticated matches. We propose an extension of Interaction Nets which facilitates nested pattern matching on interaction rules. We then define a practical compilation scheme from(More)
This paper is about a new implementation technique for interaction nets—a visual programming language based on graph rewriting. We compile interaction nets to C, which offers a robust and efficient implementation, in addition to portability. In the presentation of this work we extend the interaction net programming paradigm to introduce a number of features(More)
The intestinal absorption of cholesterol and beta-sitostanol (the saturated analogue of beta-sitosterol) were measured and their absorptions compared in the presence and absence of cholestyramine. After test meals containing [(3)H]cholesterol and [(14)C]beta-sitostanol without added cholestyramine, 4-day fecal collections yielded an average of 51% of the(More)
The effect of DMSO on cholesterol and bile acid metabolism was studied in rats. Male Sprague-Dawley rats were randomly assigned to one of two groups and given either tap water or 2% DMSO (v/v) in tap water to drink for 9 days. Both food (stock rat diet) and water were available ad libitum. Animals in both groups gained weight equally throughout the study.(More)
The tottering (tg/tg) mouse is a genetic model of human generalized epilepsy; these mice exhibit spontaneous absence seizures accompanied by bilaterally synchronous spike-wave discharges (6). The mechanism(s) for seizure activity are unknown in these mice. Several recent studies have suggested that membrane lipid peroxidation may be causally involved in(More)
We hypothesized that acute measles infection imposes severe metabolic demands on malnourished children. Nigerian rural communities, characterized by severe poverty and extensive malnutrition, served as site for this study. Sixty-five children (mean [+/-SD] age 2.67 +/- 1.96 years) with measles and a randomly selected equal number of children (age 2.83 +/-(More)
Chenodeoxycholic acid (CDCA) was fed to pregnant rats at the 0.25% level in the diet from Day 11 of gestation to delivery in order to evaluate the effects on (1) maternal tissue bile acid composition, (2) neonatal tissue bile acid composition and cholesterol-7 alpha-hydroxylase activity, and (3) maternal, neonatal, and postnatal liver morphology.
