1. The Effect of Hemodynamic Parameters on Cerebral Oxygenization During Carotid Endarterectomy
Abstract Objective/Introduction: Near-infrared spectroscopy (NIRS) is a non-invasive technique to detect cerebral ischemia by monitoring changes in regional cerebral oxygenation (rSO2) in the frontal lobes. However, there are no studies showing the changes in NIRS values in response to hemodynamic variations during stages of carotid endarterectomy (CEA) pro

2. Study on the mechanism and therapeutic effect of Antelope horn treatment on cerebral ischemia reperfusion injury of mouse
Abstract To the mechanism and therapeutic effect of Antelope horn treatment on cerebral ischemia reperfusion injuries under different levels of concentration. The process is as follows: (1) establish MCAO mouse model, test the modelling using traction and open field experiments, use TTC staining to detect the protective effect of Antelope horn treatment on c

3. Effect of dihydroferulic acid obtained from fermented rice bran extract on neuroprotection and behavioral recovery in an ischemic rat model
Abstract This study aimed to evaluate whether dihydroferulic acid (dFA) promoted the viability of H2O2-treated PC12 cells and functional recovery from ischemic injury. The animals were divided into four groups for the study: (1) the vehicle treated (saline, 1 mL/kg), (2) dFA 5 mg/kg treated, (3) dFA10 mg/kg treated, and (4) dFA 20 mg/kg treated groups. Neuro

4. 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

5. Anxiolytic-like and proneurogenic effects of Trichilia catigua ethyl-acetate fraction in mice with cerebral ischemia
Abstract Trichilia catigua A. Juss., Meliaceae, known as "catuaba" in Brazil, has been popularly used as a tonic for fatigue, impotence and memory deficits. Previously, we have demonstrated that T. catigua ethyl-acetate fraction exerted antidepressive-like effects in mice. Affective-like symptoms are also well recognized outcome of cerebral ischemia in clini

6. Aneurysmal subarachnoid hemorrhage: current concepts and updates
RESUMO Hemorragia subaracnoidea aneurismática (aHSA) é uma condição com grande variação de incidência mundialmente. No Brasil, não dispomos de números epidemiológicos exatos. A apresentação clínica mais comum da HSA é a cefaleia, usualmente descrita como a pior da vida. A tomografia de crânio, quando feita nas primeiras 6 horas do ictus, tem u

7. Effects of physical exercise on skeletal muscles of rats with cerebral ischemia
Physical exercise is a known preventive and therapeutic alternative for several cerebrovascular diseases. Therefore, the objective of the present study was to evaluate the motor performance and histomorphometry of the biceps brachii, soleus, and tibialis anterior muscles of rats submitted to a treadmill training program prior to the induction of cerebral isc

8. Analysis of Caspase-9 protein and microRNAs miR-21, miR-126 and miR-155 related to the apoptosis mechanism in the cerebellum of rats submitted to focal cerebral ischemia associated with an alcoholism model
RESUMO O objetivo deste estudo foi analisar o cerebelo de ratos submetidos à isquemia cerebral focal experimental, por oclusão da artéria cerebral média por 90 minutos, seguida de reperfusão por 48 horas, associada a um modelo de alcoolismo. Métodos Foram utilizados 50 ratos Wistar adultos, subdivididos em cinco grupos experimentais: grupo controle (

9. 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

10. Antiphospholipid syndrome and neurofibromatosis type I: a coincidence or new association?
RESUMO | Inúmeros estudos têm relatado anomalias vasculares estruturais e isquemia associada com à neurofibromatose tipo 1 que, acredita-se, resultam da disfunção da neurofibromina, a proteína tipo 1 da neurofibromatose. Casos documentados de síndrome antifosfolípide associada que atendem aos critérios diagnósticos aceitos são excepcionalmente rar

11. Effects of icariside II on brain tissue oxidative stress and Nrf2/HO-1 expression in rats with cerebral ischemia-reperfusion injury
Abstract Purpose: To investigate the effects of icariside II on brain tissue oxidative stress and Nrf2/HO-1 expression in rats with cerebral ischemia-reperfusion injury (CIRI). Methods: One hundred SD rats were randomly divided into sham-operated, model, and 5, 10 and 20 mg/kg icariside II groups, 20 rats in each group. The middle cerebral artery occlusio

12. Protective effect of extract of the Camellia japonica L. on cerebral ischemia-reperfusion injury in rats
RESUMO Objetivo: Investigamos o efeito protetor do extrato da flor de Camellia japonica L. (ECJ) na lesão de reperfusão isquêmica cerebral (I/R) em ratos. Métodos: A lesão de I/R de rato foi induzida por uma oclusão da artéria cerebral média por 90 minutos e reperfusão por 48 horas. Os animais receberam uma injeção intravenosa uma vez ao dia de
