Background: In recent years, the role of neurotrophins and their receptors in peripheral tissues has been great interest. At a metabolic level, brain-derived neurotrophic factor (BDNF) its receptor trkB have reported to participate insulin secretion from pancreas response increases circulating blood glucose. Objetive: To determines BDNF-trkB pathway pancreatic morphology rats fed cafeteria-style diet for 16 weeks. Methods: For study, male Wistar strain were divided into three groups as...

Hepatocellular carcinoma (HCC) is the most common primary liver cancer, often diagnosed at advanced stages due to insufficient early screening and monitoring. MicroRNAs (miRNAs) are key regulators of gene expression potential biomarkers for cancer diagnosis. This study investigated diagnostic miRNAs in Extracellular Vesicles (EVs) from HCC. miRNA EVs was analyzed using HCC cell lines, circulating a Diethylnitrosamine (DEN)-induced tumor rat model, plasma samples patients. Receiver Operating...

Different studies in experimental diabetes models suggest that zinc oxide nanoparticles (ZnONPs) are useful as antidiabetic agents. However, this evidence was performed and measured long-term treatments with repeated doses of ZnONPs. This work aimed to evaluate the ZnONPs acute effects on glycemia during next six h after an oral or intraperitoneal administration treatment healthy diabetic rats. In study, streptozotocin-nicotinamide male Wistar rats were used a model. 10 mg/kg did not modify...

The aim of this work was to determine whether Capsaicin may exert a vascular regulation through the activation CB1 and/or CB2 receptors causing vasorelaxation in rat aorta. Our results show location TRPV1 mainly endothelial and smooth muscle cells membrane. Nevertheless, caused artery mechanism independent TRPV1, since specific antagonists Capsazepine SB-366791 did not block effect Capsaicin. Because significant expression has been previously reported aorta, we used for these two prior...

The pathologic cardiac remodeling has been widely documented; however, the physiological induced by pregnancy and its reversion in postpartum are poorly understood. In present study we investigated changes collagen I (Col I) III III) mRNA protein levels left ventricle from rat heart during postpartum. Col expression samples were analyzed using quantitative PCR. Data obtained gene show that upregulated with contrast to expression, evaluated western blot showed is downregulated pregnancy....

The function and morphology of β-cells is largely dependent on insulin demand. As cover a bigger cell proportion in pancreas islets, changes producer cells affect the whole pancreatic islet morphology. Growth factors as neurotrophins regulate physiology, besides; physical exercise increases sensitivity, further modifies brain derived neurotrophic factor (BDNF) concentration plasma. aim this study was to investigate effects chronic (running treadmill for 8 weeks) intensity morphometry healthy...

We evaluated changes in passive mechanical properties cardiac tissues during rat pregnancy. Left and right ventricular free walls were dissected from hearts of nonpregnant, late-pregnant, postpartum rats. Mechanical experiments strips done by stretch-release cycles using a step motor. The results show that pregnancy, there is hypertrophy associated with (1) an increase myocyte size, particularly augmented length, (2) decrease tension developed the myocardial walls, (3) both elastic modulus...

Background and objectives: Adipose tissue skeletal muscle secrete adiponectin, a hormone abundantly secreted by adipocytes, that through the adiponectin receptor, regulate glucose lipid metabolism. Adiponectin appears to protect muscles from inflammatory damage induced oxidative stress. It has been suggested decreased levels could be associated with pathologic conditions, including obesity diabetes. Furthermore, some studies suggest exercise have beneficial effect increasing levels, but this...

Background and objectives: Cardiac remodeling in pregnancy postpartum is poorly understood. The aim of this study was to evaluate changes cardiac fibrosis (pericardial, perivascular, interstitial), as well the expression matrix metalloproteinases (MMP-1, MMP-2, MMP-9) their inhibitors (Tissue metalloproteinases, TIMP-1 TIMP-4) during late rat left ventricle. Materials Methods: Female Sprague-Dawley rats were used for study. Rats divided three groups: non-pregnant, pregnancy, postpartum....
