2. Cardioprotection of Rosuvastatin Pre-conditioning on Myocardial Ischemia / Reperfusion Injury in a Rat Model
Abstract This study aimed to investigate the cardioprotection of rosuvastatin pre-conditioning (R-Pre) in a rat model of myocardial ischemia / reperfusion (I/R). Male SD rats were assigned into three groups: sham group, I/R group and R-Pre group. Rats in I/R group and R-Pre group received ischemia for 30 min and reperfusion for 2 h. In R-Pre group, rats rec

3. Pharmacological modulation of b-adrenoceptors as a new cardioprotective strategy for therapy of myocardial dysfunction induced by ischemia and reperfusion
Abstract Purpose: To evaluate the cardioprotective response of the pharmacological modulation of β-adrenergic receptors (β-AR) in animal model of cardiac ischemia and reperfusion (CIR), in spontaneously hypertensive (SHR) and normotensive (NWR) rats. Methods: CIR was induced by the occlusion of left anterior descendent coronary artery (10 min) and reper

4. Cardioprotective effect of preconditioning is more efficient than postconditioning in rats submitted to cardiac ischemia and reperfusion
Abstract Purpose: To investigate the cardioprotective effects of ischemic preconditioning (preIC) and postconditioning (postIC) in animal model of cardiac ischemia/reperfusion. Methods: Adult rats were submitted to protocol of cardiac ischemia/reperfusion (I/R) and randomized into three experimental groups: cardiac I/R (n=33), preCI + cardiac I/R (n=7) an

5. Aerobic exercise training induces superior cardioprotection following myocardial ischemia reperfusion injury than a single aerobic exercise session in rats
Abstract AIM To compare the amount of cardioprotection induced by a single exercise session with those achieved after an 8-week aerobic exercise training following ischemia reperfusion injury in rats. METHODS Twenty-five male Wistar rats (250-300g) were assigned into a group submitted to physical training (TR; n=12) or a single maximal exercise session (EX

6. Cardioprotection against experimental myocardial ischemic injury using cornin
Phosphorylated-cyclic adenosine monophosphate response element-binding protein (Phospho-CREB) has an important role in the pathogenesis of myocardial ischemia. We isolated the iridoid glycoside cornin from the fruit of Verbena officinalis L, investigated its effects against myocardial ischemia and reperfusion (I/R) injury in vivo, and elucidated its potentia

7. The role of oxytocin in cardiovascular regulation
Studies of body volume expansion have indicated that lesions of the anteroventral third ventricle and median eminence block the release of atrial natriuretic peptide (ANP) into the circulation. Detailed analysis of the lesions showed that activation of oxytocin (OT)-ergic neurons is responsible for ANP release, and it has become clear that activation of neur

8. Quercetin postconditioning attenuates myocardial ischemia/reperfusion injury in rats through the PI3K/Akt pathway
Quercetin (Que), a plant-derived flavonoid, has multiple benefical actions on the cardiovascular system. The current study investigated whether Que postconditioning has any protective effects on myocardial ischemia/reperfusion (I/R) injury in vivo and its potential cardioprotective mechanisms. Male Sprague-Dawley rats were randomly allocated to 5 groups (20

9. High plasma concentrations of asymmetric dimethylarginine inhibit ischemic cardioprotection in hypercholesterolemic rats
A low concentration of nitric oxide associated with a high concentration of asymmetric dimethylarginine (ADMA) can explain the lack of ischemic cardioprotection observed in the presence of hypercholesterolemia. The objective of the present study was to evaluate the effect of hypercholesterolemia on ischemic pre- and postconditioning and its correlation with

10. Participacão do Sistema Calicreína-cininas na cardioproteção promovida pela atividade física e sua modulação pela sobrecarga adrenérgica induzida pelo isoproterenol em miocárdio de ratos. / Participation of the Calicreína-cininas System in the cardioproteção promoted for the physical activity and its modulation for the induced adrenérgica overload for isoproterenol in myocardium of rats.
Uma vez que o treinamento físico exerce uma cardioproteção, a expressão miocárdica do sistema calicreína-cininas pode contribuir neste sentido. Para testar essa hipótese em um modelo de hiperatividade β-adrenérgica, ratos Wistar machos foram randomizados em quatro grupos: ratos sedentários não tratados (Con); sedentários tratados com isoprote

11. Cardioprotection conferred by exercise training is blunted by blockade of the opioid system
OBJECTIVES: To investigate the effect of opioid receptor blockade on the myocardial protection conferred by chronic exercise and to compare exercise training with different strategies of myocardial protection (opioid infusion and brief periods of ischemia-reperfusion) preceding irreversible left anterior descending coronary ligation. INTRODUCTION: The acute

12. Prior exercise training does not prevent acute cardiac alterations after myocardial infarction in female rats
OBJECTIVE: This study aimed to investigate whether previous exercise training could prevent or attenuate acute cardiac alterations after myocardial infarction. METHODS: Female rats were submitted to swim training (1 h/day; 5 days/week) or allowed to remain sedentary for 8 weeks. Afterwards, they were randomly assigned to left coronary artery occlusion or sha
