We tested two hypotheses about monoamine neurotransmitters in two strains of rats that differ in their sensitivity to obesity when eating a high-fat diet; 1) that the concentrations of norepinephrine and serotonin and of their metabolites differ in the extracellular fluid of the ventromedial
The 5 HT(1A) receptor agonist 8-hydroxy-2-(di-n-propylamino)-tetraline (8-OH-DPAT) increases the food intake of satiated Zucker rats, both lean and obese. Associated with this increased intake are changes in the hypothalamic content of serotonin and its metabolite, 5-HIAA (5-hydroxyindole-3-acetic
OBJECTIVE
The constellation of metabolic abnormalities seen in metabolic syndrome (MetS) has been linked to atherosclerosis and adverse cardiovascular outcomes due to heightened inflammation. Accumulating evidence suggests that peripheral 5-hydroxyindole-3-acetic acid (5-HIAA), the derivative
1. Osborne-Mendel (O-M) rats displayed differences in brain and systemic tryptophan metabolism. O-M rats had decreased brainstem tryptophan-5-hydroxylase activity and decreased serotonin (5-HT) levels as compared to Sprague-Dawley rats. However, brain tryptophan levels were actually increased in O-M
Amino acid metabolites in biofluids are associated with high body mass index (BMI) and cardiometabolic abnormalities. However, prospective investigations regarding these associations are few, particularly among young individuals. Moreover, little is presently known about the impact of long-term high
The JCR:LA-cp rat is a strain carrying the mutant cp (corpulent) gene. Animals that are homozygous cp are hyperphagous, hyperinsulinemic, hyperlipidemic, and obese. Corpulent male rats, but not females or lean rats, develop atherosclerotic lesions and myocardial lesions. Since the myocardial lesions
Sprague-Dawley (S-D) and Osborne-Mendel (O-M) rats were fed either a low-fat diet (5 percent corn oil) or high-fat diet (20 percent corn oil) for a six-week-period. Brainstem and duodenal levels of tryptophan, serotonin (5-hydroxytryptamine, 5-HT) and 5-hydroxyindole-3-acetic acid (5-HIAA) were not
