Chronic heart failure-induced skeletal muscle atrophy, necrosis, and changes in myogenic regulatiory factors
(Int Scientific Literature, Inc, 2010-12-01)
Background: Although intrinsic skeletal muscle abnormalities can influence exercise intolerance during heart failure (HF), the factors responsible for muscle changes have not been elucidated. In this study we evaluated the ...
Acute inhibition of excessive mitochondrial fission after myocardial infarction prevents long-term cardiac dysfunction
BACKGROUND: Ischemia and reperfusion (IR) injury remains a major cause of morbidity and mortality and multiple molecular and cellular pathways have been implicated in this injury. We determined whether acute inhibition ...
Comparison of MB fraction of creatine kinase mass and troponin I serum levels with necropsy findings in acute myocardial infarction
(EXCERPTA MEDICA INC-ELSEVIER SCIENCE INC, 2008)
Serum levels of troponin and heart-related fraction of creatine kinase (CK-MB) mass are used as diagnostic and prognostic criteria in myocardial infarction, but the relation between those levels and-the necropsy-determined ...
Non-ischemic myocardial preconditioning
The reduction of infarct size produced by brief ischemic episodes prior to a sustained occlusion of a coronary artery, called ischemic preconditioning, is a well known phenomenon that occurs in several species, but its ...
Erythropoietin protects the systolic function of neonatal hearts against ischaemia/reperfusion injury
(Oxford Univ Press IncCaryEUA, 2013)
Inhibition of endogenous thioredoxin-1 in the heart of transgenic mice does not confer cardioprotection in ischemic postconditioning
(Pergamon-Elsevier Science Ltd, 2016-12)
Thioredoxin-1 maintains the cellular redox status and decreases the infarct size in ischemia/reperfusion injury. However, whether the increase of thioredoxin-1 expression or its lack of activity modifies the protection ...
Activated macrophages as a feeder layer for growth of resident cardiac progenitor cells
The adult heart contains a population of cardiac progenitor cells (CPCs). Growing and collecting an adequate number of CPCs demands complex culture media containing growth factors. Since activated macrophages secrete many ...
Echocardiographic detection of congestive heart failure in postinfarction rats
(Amer Physiological Soc, 2014)
Myocardial triggers involved in remote ischemic preconditioning activation
(Wiley Blackwell Publishing, Inc, 2016-06)
It has been proposed that remote ischaemic preconditioning (rIPC) activates a parasympathetic neural pathway. However, the myocardial intracellular mechanism of rIPC remains unclear. Here, we characterized some of the ...
