Several PPAR-gamma agonists containing a thiazolidinedione moiety (referred to as glitazones) have been proposed to be neuroprotective and appear to alter mitochondrial function. Recently, a search for mitochondrial proteins that bind pioglitazone…

A novel outer mitochondrial membrane protein containing [2Fe-2S] clusters, mitoNEET was first identified through its binding to the anti-diabetic drug pioglitazone. Pioglitazone belongs to a family of drugs that are peroxisome proliferator-activated…

Previous studies have shown that tachykinin peptide ligands of the tachykinin NK1 receptor exhibit functional selectivity with respect to signal activation and desensitization. The differences are most dramatic between the naturally occurring…

The interactive effects between gender and a selective alteration in the neurotrophin, brain-derived neurotrophic factor (BDNF) upon methamphetamine (MA)-induced neurotoxicity of the nigrostriatal dopaminergic (NSDA) system were assessed. MA…

We examined the effects of varying concentrations of testosterone propionate (T) treatment within intact and gonadectomized male and female mice with regard to its capacity to alter striatal dopamine (DA) depletion in response to a neurotoxic regimen…

Two groups of eight male Normalized/National Institutes of Health (N/Nih) rats were used in a food-motivated, 2-lever drug discrimination task with one group being trained to discriminate between 10 mg/kg cocaine vs. 1 g/kg ethanol, whereas the…

The effects of varying doses of nicotine infusion upon spontaneous (basal) and subsequent potassium chloride-stimulated dopamine and 3,4-dihydroxyphenylacetic acid (DOPAC) output from superfused corpus striatal tissue fragments of male rats were…

This study describes the results of a 'side-by-side' comparison of two measurement techniques and two dosing regimens in a discrimination study using rats trained to either 10 mg/kg cocaine or 2 mg/kg 3,4-methylenedioxymethamphetamine (MDMA). The…

Drug discrimination studies were conducted in six male Sprague-Dawley rats trained to discriminate the interoceptive cues produced by 10 mg/kg cocaine in an effort to investigate if there is stimulus generalization to phentermine or phentermine +…

Two groups of N/Nih male rats were trained to discriminate saline vehicle from either 2.0 mg/kg (n = 10) or 10.0 mg/kg (n = 10) cocaine in a food-motivated, two-lever operant paradigm. The rats trained at the low-dose cocaine took a significantly…

The benzodiazepine flunitrazepam (Rohypnol) was employed to control differentially discriminative performance in 10 Sprague-Dawley rats on a food-motivated FR10 schedule. The training dose was 2.5 mg/kg, and 20 min was employed between…

A two-lever, food-motivated, operant technique was employed to train the purportedly serotonergically dysfunctional Fawn-Hooded (FH) rat to discriminate 1.5 mg/kg MDMA. Once all 10 male subjects learned the MDMA-vehicle discrimination at criterion…

In order to identify an acute spinally mediated pharmacological effect of a bioactive substance, without incurring untoward supraspinal effects, it is necessary to administer the agent locally onto the spinal cord. The procedure delineated herein…

The aim of this study was to identify factors that are associated with patients achieving goal A1c after 6 months in a pharmacist-managed diabetes clinic. This study is a descriptive, retrospective chart review of patients with type 2 diabetes…

A cascade of events follows binding of an agonist ligand to the tachykinin NK(1) receptor. These events include activation of multiple signal transduction pathways as well as cellular modulation of receptor function by the process of desensitization.…

Transient receptor potential vanilliod 1 (TRPV1) channels have recently been postulated to play a role in the vascular complications/consequences associated with diabetes despite the fact that the mechanisms through which TRPV1 regulates vascular…

Previously, we reported that, in the rat, pressor responsiveness to vasopressin (VP) is higher in males than in females during most phases of the estrous cycle. To explore the role of the vasculature in this phenomenon, we examined vascular…

This study was conducted to determine whether increased myocardial energy demand plays a role in norepinephrine (NE)-induced left ventricular (LV) dysfunction. A range of arterial pressure-heart rate (P-R) products (myocardial energy demand) was…

We measured agonist-induced changes in the iliac artery blood flow velocity (IFV) independent of baroreflex-mediated compensatory mechanisms in chronically instrumented New Zealand White rabbits (n = 8). Animals were instrumented with a Doppler flow…
