It is well established that patterns of sensory input can affect neuroplastic changes during early development. The scope and consequences of experience-dependent plasticity in the adult are less well understood. We studied the possibility that repeated exposure to trains of stroboscopic stimuli could induce a sensitized and potentially aberrant response in ordinary individuals. Chronic electro...

Objective(s): Doxorubicin (DXR)-induces glomerular atrophy and fibrosis in rat kidneys. The objective of the current study was to investigate the protective effects of valsartan on DXR-induced glomerular toxicity and its mechanisms of actions in rats. Materials and Methods: Male Sprague-Dawley (SD) rats were divided into four groups, and each group contains ten rats. First group was control and...

Orexin/hypocretin terminals innervate noradrenergic locus coeruleus (LC) neurons that project to the prefrontral cortex, which may influence spontaneous physical activity (SPA) and energy balance. Obesity-resistant (OR) rats have higher orexin receptors (OXR) mRNA in the LC and other brain regions, as well as lower adiposity compared with obese rats. These findings led us to hypothesize that or...

objective(s):the present study investigated the effect of long-term mild cerebral hypoperfusion induced by permanent unilateral (right) common carotid artery occlusion (uco) on the dorsal hippocampal neurons in rats. materials and methods:sixty four male sprague-dawley rats aged 4 months were divided into two groups of sham and uco. these two groups were further divided into 4 sets of histopath...

Metabolic dysfunctions might play a crucial role in the pathophysiology of thyroid dysfunctions. This study aimed to investigate the impact of a controlled diet (normal versus high fat feeding) on hypothyroid and hyperthyroid Sprague Dawley rats. Female Sprague Dawley rats (n = 66) were grouped into normal diet (n = 30) and high-fat diet (n = 36) groups and subdivided into controls, hypothyroid...

Transforming growth factor-beta/Smad pathway plays an important role in the pathogenesis of neurological diseases. This study investigated effects high fat diet and alcohol dependence on memory expression transforming prefrontal lobe, hippocampus cerebellum rats. Sixty male Sprague Dawley rats were randomly divided into control group, group alcohol+highfat group. Morris water maze test was perf...

The aim of the present study was to investigate toxic effects aluminum chloride (AlCl3) on reproductive organs, as well as, protective effect propolis against AlCl3-induced toxicity in male rats. Eighty adult fertile Sprague Dawley albino rats were randomly divided into four groups 20 each. Group 1: served control group and received only distilled water. 2: a daily ingestion 80 mg/kg AlCl3. 3: ...

The hypothesis that BHE/Cdb rats with mutations in their mitochondrial genome might accommodate this mutation by changing their food intake patterns was tested. Four experiments were conducted. Experiments 1 and 2 examined food intake patterns of BHE/Cdb rats fed a stock diet or BHE/Cdb and Sprague-Dawley rats fed a high-fat diet from weaning. Experiment 3 examined the daily rhythms of respirat...

In this study, we compared the effects of Calendula and Alpha ointment in the treatment of burn wounds and compare its results with silver sulfadiazine (SSD). Seventy-five male Sprague-Dawley rats were divided into five groups, and similar burn ulcers were produced on anterior surface of thigh of rats. The first group of rats no treatment was applied, base gel was applied topically to group II,...
