3. Astragaloside IV alleviates myocardial ischemia-reperfusion injury in rats through regulating PI3K/AKT/GSK-3β signaling pathways
Abstract Purpose: To investigate the effect of astragaloside IV (As-IV) on myocardial ischemia-reperfusion (I/R) injury in rats and reltaed mechanisms. Methods: Sixty rats were randomly divided into sham-operated, control I/R and 2.5, 5 and 10 mg/kg As-IV groups, 12 rats in each group. The later three groups were intragastrically administered with As-IV fo

4. Protective effect of crocetin from Crocus sativus L. on myocardial ischemia-reperfusion injury in rats
Abstract This study investigated the protective effect of crocetin from Crocus sativus L. on myocardial ischemia-reperfusion injury (MIRI) in rats. Sixty SD rats were randomly divided into sham-operated, model, and low-, medium- and high-dose crocetin groups. Later 3 groups were intragastrically administrated with 10, 20 and 40 mg/kg crocetin from Crocus sat

5. The role of PI3K/Akt signal pathway in the protective effects of propofol on intestinal and lung injury induced by intestinal ischemia/reperfusion
Abstract Purpose: To investigate the role of PI3k/Akt signal pathway in the protective effects of propofol on intestinal and lung injury induced by intestinal ischemia/reperfusion(I/R). Methods: Male Sprague-Dawley rats were subjected to 45 min of ischemia by occluding the superior mesenteric artery and to 2h of reperfusion to establish the model of I/R. T

6. Salvinorin A preserves cerebral pial artery autoregulation after forebrain ischemia via the PI3K/AKT/cGMP pathway
This study aimed to investigate the protective effect of salvinorin A on the cerebral pial artery after forebrain ischemia and explore related mechanisms. Thirty Sprague-Dawley rats received forebrain ischemia for 10 min. The dilation responses of the cerebral pial artery to hypercapnia and hypotension were assessed in rats before and 1 h after ischemia. The

7. Ginsenoside Rg1 protects human renal tubular epithelial cells from lipopolysaccharide-induced apoptosis and inflammation damage
Ginsenoside Rg1, one of the most notable active components of Panax ginseng, has been widely reported to exert anti-inflammatory actions. This study aimed to reveal whether ginsenoside Rg1 also exhibits beneficial roles against lipopolysaccharide (LPS)-induced apoptosis and inflammation in human renal tubular epithelial cells, and to evaluate the potential r

8. The role of histone deacetylase inhibitors in regulation of Akt/GSK-3β signaling pathway in mice following transient focal cerebral ischemia
Abstract Purpose: To investigate whether the neuroprotective effect of TSA on cerebral ischemia reperfusion injury is mediated by the activation of Akt/GSK-3β signaling pathway. Methods: Mice were randomly divided into four groups (n=15): sham group (S); ischemia reperfusion group (IR); ischemia reperfusion and pretreated with TSA group (IR+T); ischemia

9. Testosterona e Exercício Voluntário, Individualmente ou em Conjunto, Aumentam a Ativação Cardíaca de AKT e ERK1/2 em Ratos Diabéticos
Resumo Fundamento: Angiogênese prejudicada em tecido cardíaco é uma das principais complicações das diabetes. As vias de sinalização da proteína-quinase B (AKT) e a quinase regulada por sinal extracelular (ERK) exercem um importante papel durante a formação de uma rede similar à capilar no processo de angiogênese. Objetivos: Determinar os efeit

10. INFLUÊNCIA DE DIFERENTES PROTOCOLOS DE TREINAMENTO FÍSICO SOBRE A FOSFORILAÇÃO DA PROTEÍNA AKT EM MÚSCULO ESQUELÉTICO E SENSIBILIDADE À INSULINA DE RATOS OBESOS
RESUMOO Objetivo deste estudo foi investigar os efeitos de diferentes protocolos de treinamento físico (TF) sobre a sensibilidade à insulina (SI) e a fosforilação da Akt (p-Akt) no músculo de ratos obesos. Os animais foram distribuídos em quatro grupos: Controle: recebeu dieta padrão (C); Obeso sedentário: recebeu dieta hiperlipídica (DHL) por 12 se

11. Acute hyperglycemia prevents dexmedetomidine-induced preconditioning against renal ischemia-reperfusion injury
PURPOSE: To investigate the effects of acute hyperglycemia on dexmedetomidine-induced preconditioning against renal ischemia-reperfusion injury. METHODS: Sprague-Dawley rats were randomly arranged to the normoglycemic (NG) or hyperglycemic group (HG), with each group further divided into sham (no I/R injury), I/R (ischemia-reperfusion) and dex (given by dex

12. Propofol pretreatment attenuates lipopolysaccharide-induced acute lung injury in rats by activating the phosphoinositide-3-kinase/Akt pathway
The aim of this study was to investigate the effect of propofol pretreatment on lipopolysaccharide (LPS)-induced acute lung injury (ALI) and the role of the phosphoinositide-3-kinase/protein kinase B (PI3K/Akt) pathway in this procedure. Survival was determined 48 h after LPS injection. At 1 h after LPS challenge, the lung wet- to dry-weight ratio was examin
