Intra-striatal infusion of a high dose (100 microg/3 microl) of methamphetamine produced long-lasting depletions of striatal dopamine and serotonin in both male and female mice. Male mice exhibited a greater depletion of striatal dopamine and serotonin than female mice. A similar trend of sexual differences was observed when 4 cumulative doses of(More)
Four consecutive doses (10 mg/kg) of methamphetamine, s.c., produced a substantial striatal dopamine depletion in both sexes of BALB/c and C57BL/6J mice. Male C57BL/6J mice exhibited greater dopamine depletions in the striatum compared to female C57BL/6J mice. In contrast, male and female BALB/c mice demonstrated an equivalent magnitude of striatal dopamine(More)
DNA polymerase alpha-primase is known to be phosphorylated in human and yeast cells in a cell cycle-dependent manner on the p180 and p68 subunits. Here we show that phosphorylation of purified human DNA polymerase alpha-primase by purified cyclin A/cdk2 in vitro reduced its ability to initiate simian virus 40 (SV40) DNA replication in vitro, while(More)
Recent studies indicate a possible link between serum cholesterol level, beta-amyloid (Abeta) peptide concentrations, and the incidence of Alzheimer's disease (AD). In the present report, the effects of dietary cholesterol on Abeta and apolipoprotein E (APOE) levels in several brain regions were examined using diet-induced hypercholesterolemic rabbits as(More)
This study used multidimensional self report assessments to measure perfectionism, impulsivity and obsessive compulsive characteristics in females with anorexia nervosa (AN), bulimia nervosa (BN) and in matched healthy controls (HC). The Frost Multidimensional Perfectionism Scale (FMPS), Barrett Impulsivity Scale (BIS) and Obsessive Compulsive(More)
Formation of 6-hydroxydopamine (6-OHDA) has been posited in the striatum following methamphetamine treatment and plays a critical role in methamphetamine-induced nigrostriatal dopaminergic toxicity. We used high performance liquid chromatography electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/MS) to determine the formation of 6-OHDA by the(More)
