1. Protective Effects of Adrenomedullin on Rat Cerebral Tissue After Transient Bilateral Common Carotid Artery Occlusion and Reperfusion
Abstract Objective: We aimed to investigate the protective effect of adrenomedullin (ADM) on cerebral tissue of rats with cerebral ischemia/reperfusion (I/R) injury. Methods: Thirty-two Wistar rats were randomized into four groups (n=8). In the I/R Group, bilateral common carotid arteries were clamped for 30 minutes and, subsequently, reperfused for 120 mi

2. Beta-glucan attenuates cerebral ischemia/reperfusion-induced neuronal injury in a C57BL/J6 mouse model
Beta-glucans (βg), that have many useful effects on human health, are natural polysaccharides. Our aim in this study was to determine useful effect of βg against oxidative and neuronal damage caused by global cerebral ischemia/reperfusion (IR) in stroke imitated mice via surgical operation. A total of 40 mice divided into four equal groups randomly. The gr

3. Cortical branches of the middle cerebral artery in silver fox (Vulpes vulpes)
ABSTRACT: The study of the vascularization of the cerebrum in silver fox was performed on 80 cerebral hemispheres. It was found that the middle cerebral artery is the strongest vessel supplying blood to the cerebrum. The artery gets divided into ten permanent branches. Two olfactory arteries supply the region of the cerebrum located on the border between the

4. The protective cardiac effects of Β-myrcene after global cerebral ıschemia/reperfusion in C57BL/J6 mouse
ABSTRACT PURPOSE: To investigate the protective effect of β-myrcene (MYR) on oxidative and histological damage in mice heart tissue caused global cerebral ischemia/reperfusion (IR) in C57BL/J6 mice. METHODS: Animals(n=40) were randomly divided into four groups: (1)control, (2)IR, (3)MYR and (4)MYR+IR. The control group was received 0.1% carboxymethyl cell

5. Aberrant Origin of Vertebral Artery and its Clinical Implications
Abstract Aberrant origin of vertebral artery is rare. The anatomical features and clinical significance of this lesion remain to be clarified. A comprehensive collection of the pertinent literature resulted in a cohort of 1286 cases involving 955 patients and 331 cadavers. There were more left than right and more unilateral than bilateral aberrant vertebral

6. Expression of Sphingosine-1-phosphate (S1P) on the cerebral vasospasm after subarachnoid hemorrhage in rabbits
PURPOSE: To demonstrate the relationship between of sphingosine-1-phosphate (S1P) expression and subarachnoid hemorrhage (SAH). METHODS: The basilar arteries from a "double-hemorrhage" rabbit model of SAH were used to investigate the relation between S1P expression and SAH. Various symptoms, including blood clots, basilar artery cross-sectional area, and S

7. Physical exercise prevents motor disorders and striatal oxidative imbalance after cerebral ischemia-reperfusion
Stroke is the third most common cause of death worldwide, and most stroke survivors present some functional impairment. We assessed the striatal oxidative balance and motor alterations resulting from stroke in a rat model to investigate the neuroprotective role of physical exercise. Forty male Wistar rats were assigned to 4 groups: a) control, b) ischemia, c

8. Preconditioning with L-alanyl-glutamine upon cerebral edema and hypocampus red neurons counting in rats subjected to brain ischemia /reperfusion injury
PURPOSE:To evaluate the effects of the dipeptide L-alanyl-glutamine (L-Ala-Gln) as a preconditioning agent to potentially promote reduction in the intensity of lesion or induction of resilience in rats subjected to global cerebral ischemia/reperfusion (I/R) injury.METHODS:Thirty-six male Wistar rats weighing 280-300g were randomly assigned to six groups (n=6

9. The correlation between lateralization of intracerebral hemorrhage in basal ganglia and handedness
PURPOSE: To investigate the correlation between lateralization of cerebral basal ganglia hemorrhage and handedness. METHODS: Medical records and computed tomography (CT) scans for 84 patients with primary hypertensive intracerebral hemorrhage (ICH) in basal ganglia were reviewed. Data of gender, age, handedness, and location of basal ganglia hematoma were st

10. Influence of the gender on cerebral vascular diameters observed during the magnetic resonance angiographic examination of willis circle
The present study evaluated the calibers and anatomic configurations based on the Magnetic Resonance analysis (MRA), assaying the cerebral vascular territories and sex-linked variations. A randomized sample of 30 angiographic examinations in adult patients of both sexes was obtained and components of the circle of Willis were identified. Branch diameters wer

11. Efeito do exercício físico durante a gravidez sobre o fluxo sanguíneo feto-placentário e o crescimento fetal : ensaio controlado e aleatorizado / Effect of exercise during pregnancy on the blood flow fetal-placental and fetal growth : randomized controlled trials
Introduction: Fetal growth has always been one of the major concerns regarding the practice of exercise during pregnancy, with discussions on whether the redistribution of fetoplacental blood flow during physical exercise and the bypass of blood from the viscera to the muscles could lead to transitory fetal hypoxia. Objective: To study the. E effect of super

12. Sistematização das artérias da base do encéfalo e suas fontes de suprimento sanguíneo em coelho da raça Nova Zelândia (Oryctolagus cuniculus)
Foram utilizados 30 encéfalos de coelhos Nova Zelândia (Oryctolagus cuniculus), injetados com látex, corado em vermelho, com objetivo de sistematizar as artérias da base do encéfalo e suas fontes de suprimento sanguíneo. Sistematizou-se a origem das fontes de suprimento sanguíneo para o encéfalo e as artérias (Aa) da face ventral do mesmo, tanto à
