1. Oxiracetam ameliorates cognitive deficits in vascular dementia rats by regulating the expression of neuronal apoptosis/autophagy-related genes associated with the activation of the Akt/mTOR signaling pathway
Oxiracetam (ORC) is a commonly used nootropic drug for improving cognition and memory impairments. The therapeutic effect and underlying mechanism of ORC in vascular dementia (VaD) treatment remain unknown. In this study, 3-month-old male Sprague-Dawley rats with permanent bilateral common carotid artery occlusion-induced VaD were treated orally with low (10

2. Phospholipid composition and resistance to vitrification of in vivo blastocyst of a Brazilian naturalized porcine breed
RESUMO Blastocistos de suínos foram submetidos ao MALDI-TOF para se identificarem os principais fosfolipídios (PL). Depois, parte destes embriões (D6) foram vitrificados (n=52), ou permaneceram frescos (grupo controle, n=42). Após o aquecimento, os blastocistos foram cultivados in vitro para se avaliar a reexpansão e a eclosão (BE) às 24 e 48 horas. F

3. The role of ischemic preconditioning in the expression of apoptosis-related genes in a rat model of intestinal ischemia-reperfusion injury
Abstract Purpose: To analyze the effects of ischemic preconditioning (IPC) in the expression of apoptosis-related genes in rat small intestine subjected to ischemia and reperfusion. Methods: Thirty anesthetized rats underwent laparotomy and were drive into five groups: control (CG); ischemia (IG); ischemia and reperfusion (IRG); IPC and ischemia (IG+IPC)

4. Cytotoxic and pro-apoptotic action of MjTX-I, a phospholipase A2 isolated from Bothrops moojeni snake venom, towards leukemic cells
Abstract Background: Chronic myeloid leukemia (CML) is a BCR-ABL1+ myeloproliferative neoplasm marked by increased myeloproliferation and presence of leukemic cells resistant to apoptosis. The current first-line therapy for CML is administration of the tyrosine kinase inhibitors imatinib mesylate, dasatinib or nilotinib. Although effective to treat CML, som

5. Cytotoxic and apoptotic potential of Myristica fragrans Houtt. (mace) extract on human oral epidermal carcinoma KB cell lines
Several studies have revealed that certain naturally occurring medicinal plants inhibit the growth of various cancers. The present study was conducted to evaluate cytotoxicity and apoptotic induction potential of Myristica fragrans Houtt mace extract. The cytotoxic activity of the Myristica fragrans Houtt mace acetone extract was assayed by MTT assay on huma

6. The protection effect and mechanism of hyperbaric oxygen therapy in rat brain with traumatic injury
Abstract Purpose: To investigate the effect of hyperbaric oxygen therapy (HBOT) on traumatic brain injury (TBI) outcome. Methods: The modified Marmarou’s weight drop device was used to generate non-lethal moderate TBI rat model, and further developed in vitro astrocytes culturing system. Then, we analyzed the expression changes of interested genes and p

7. Alta expressão de XIAP e Bcl-2 pode inibir morte celular programada em glioblastomas
RESUMO O glioblastoma (GBM) é o glioma mais maligno e representa 29% de todos os tumores cerebrais. A tumorigênese está intimamente ligada à características adquiridas na via fisiológica de morte celular. Objetivo: Avaliar a expressão de genes anti-apoptóticos (XIAP e Bcl-2) e apoptóticos (citocromo C, a caspase 9, APAF-1), caspase 3 e SMAC/DIABLO,

8. Punica granatum suppresses colon cancer through downregulation of Wnt/β-Catenin in rat model
Abstract This study aims to elucidate the beneficial effect of Punica granatum L., Lythraceae (pomegranate) peel extract in the management of colon cancer induced intrarectally with N-methylnitrosourea. Adult male Sprague-Dawley rats were administered N-methylnitrosourea (2 mg in 0.5 ml water/rat) intrarectally three times/week for five weeks to induce color

9. Etanercept protects rat cardiomyocytes against hypertrophy by regulating inflammatory cytokines secretion and cell apoptosis
We aimed to investigate the effect of etanercept, a tumor necrosis factor-α (TNF-α) inhibitor, on rat cardiomyocyte hypertrophy and its underlying mechanism. Primary neonatal rat cardiomyocytes were isolated from Sprague-Dawley rats. The model of rat cardiomyocyte hypertrophy was induced by endothelin, and then treated with different concentrations of etan

11. Iodine-131 treatment of thyroid cancer cells leads to suppression of cell proliferation followed by induction of cell apoptosis and cell cycle arrest by regulation of B-cell translocation gene 2-mediated JNK/NF-κB pathways
Iodine-131 (131I) is widely used for the treatment of thyroid-related diseases. This study aimed to investigate the expression of p53 and BTG2 genes following 131I therapy in thyroid cancer cell line SW579 and the possible underlying mechanism. SW579 human thyroid squamous carcinoma cells were cultured and treated with 131I. They were then assessed for 131I

12. Heparin modulates the expression of genes encoding pro and anti-apoptotic proteins in endothelial cells exposed to intestinal ischemia and reperfusion in rats
PURPOSE:To investigate if expression of genes encoding pro and anti-apoptotic proteins in the rat enteric endothelial cells stimulated by intestinal ischemia followed by reperfusion (IR) can be modified by treatment with heparin (HP).METHODS:Eighteen adult Wistar rats were divided in three groups: sham group submitted to laparotomy only (SG), ischemia follow
