RNA synthesis in adult and senescent female Wistar rats
The process of senescence is accompanied by a progressive decrease in the functional capacities of organisms, organs, tissues and cells to maintain homeostasis. RNA synthesis plays an important role in these functional capacities. Therefore, the objectives of this thesis were to determine any …

Defining the relationship between maternal care behavior and hearing development in Wistar rats
<p>Previous studies in rodents have demonstrated the profound effects that variations in maternal care play during the postnatal development of the brain. However, much less is known about how maternal care affects hearing development. Recently, manipulations of maternal care have been investigated …

Investigating systemic effects of chronic stress on hepatic and cardiac tissue in female Wistar rats
… these molecular mechanisms within female Wistar rat cardiac and hepatic tissues collected from a chronic restraint stress (CRS) parent study. Snap-frozen cardiac and hepatic tissues from female Wistar rats exposed to 28 days of CRS (n=8) or control conditions (n=8) were analysed. Redox …

Role of Methyl Group Vitamins in Hypothalamic Development of Food Intake Regulation in Wistar Rats
… (HV, 10-fold AIN-93G) fed during pregnancy to Wistar rats produce offspring with increased food intake, obesity and characteristics of metabolic syndrome. The hypothesis that methyl group vitamins in HV gestational and pup diets modify expression of the obesogenic phenotypes in the offspring …

Expression Of Nicotinic Acetylcholine Receptor mRNA As a Function Of Age In Whole Hippocampus Preparations From Wistar Rats
… isolated bilaterally, from untreated Wistar rats at various ages (10-90 days old) were analyzed for the mRNA expression of the alpha 2, alpha 3, alpha 4, alpha 5, alpha 7, beta 2, beta 3, and beta 4 neuronal nicotinic acetylcholine receptor subunits. To do so, RNA was isolated from …

The effects of ethanolamine and magnesium on cardiac and neurological function in isoprenaline-induced myocardial infarction and cardiac hypertrophy models in adult Wistar rats Christie Nicole Garson.
Myocardial infarction (MI) is a principal cause of cardiovascular morbidity and mortality that is associated with other systemic complications. In the heart, MI can result in pump dysfunction, inducing cardiac hypertrophy which may become maladaptive leading to heart failure (HF). In the brain, MI …

Sex differences in the actions of psychoactive agents and progesterone on anxiety-related behaviour in the mongolian gerbil (meriones unguiculatus) and the effects of corticosterone on the hippocampal morphology of wistar rats (rattus norvegicus)
… in this area has been conducted using only male rats or mice. Thus, the investigation of sex differences, especially within other rodent species is still relatively ignored. There is much evidence to implicate the involvement of steroid hormones in the response to anxiety and stress. The …

INTRACRANIAL INFUSIONS OF NEUROTENSIN AGONISTS PRODUCE AN ANXIOLYTIC PROFILE IN A RAT ULTRASONIC VOCALIZATION MODEL
… ultrasonic vocalizations (USVs) produced by male Wistar rats. A reduction in the number of 22-kHz USV calls is indicative of an anxiolytic effect. The current study used a USV model to evaluate the effects of PD149163 (0.1, 1.0, and 10.0 ng) and endogenous NT (0.1, 1.0, and 10.0 µg) when …

Pituitary adenylate cyclase-activating polypeptide regulates excessive alcohol consumption
… Using genetically selected alcohol-preferring rats, a well-established animal model of alcoholism, we demonstrate that central administration of a peptide antagonist for the pituitary adenylate cyclase-activating polypeptide receptor 1 (PAC1), the cognate receptor for the neuropeptide pituitary …

Sympathetic control of carotid body excitability in hypertension: A preclinical study
… bodies of spontaneously hypertensive (SH) rats exhibit both hypertonicity and hyperreflexia (i.e., hyper-excitability), which is not fully understood. Our aim was to test whether carotid body hyper-excitability is mediated by its sympathetic innervation. Chemoreflex was activated (NaCN …

Dietary resistant starch improved maternal glycemic control in Goto-Kakizaki rat
… resistant starch in pregnant Goto-Kakizaki (GK) rats to improve glycemic control. Animal experiments were conducted to test the hypotheses. In study 1, the female GK rats were randomly grouped to receive an energy control diet or resistant starch diet. The aged matched female Wistar rats were fed …

Studies in the Folate Metabolism of Rats
… acid was studied in three-week-old weanling Wistar rats. Distribution of radioactivity after an oral dose of 2-14C folic acid was determined in urine, faeces, liver, and gut of the animals. Some of the urinary metabolites were characterized by column chromatography. The effects of an oral …
