Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive, and high-lethality fibrotic lung disease characterized by excessive fibroblast proliferation, extracellular matrix accumulation, and, ultimately, loss of lung function. Although dysregulation of some microRNAs (miRs) has been shown to play important roles in the pathophysiological processes of(More)
Enhanced external counterpulsation (EECP) is an effective noninvasive treatment of coronary artery disease. Its mechanism of action remains unknown. An acute coronary occlusion dog model was created to explore the angiogenic effect of EECP. After coronary occlusion, 12 dogs were randomly assigned to either EECP (n = 6) or control (n = 6).(More)
The iron homeostasis plays an important role in cardiac function. To understand how it acts in diabetic and ischemic myocardial injury, we studied the myocardial iron metabolism in diabetic and myocardial ischemic rats. Diabetic rats were induced by intraperitoneal injection of streptozocin (STZ) after intragastric administration of a high-fat diet while(More)
We used Western blot analysis to examine the expression of connexin 43 and M2/M3 acetylcholine muscarinic receptors (mAChR) and their interaction in ventricular myocytes from control and the ischemic heart. We confirmed that the connexin 43 and M2/ M3-mAChR were expressed in ventricular myocytes. Moreover, we showed that M3-mAChR was expressed in(More)
Tobacco smoking is a risk factor for many diseases, and nicotine is a major component of tobacco. Our previous work revealed that nicotine can induce myocardial fibrosis. This study aimed to investigate whether nicotine can induce cardiomyocyte apoptosis and to explore the mechanisms involved. Cardiomyocytes were exposed to different nicotine concentrations(More)
Atherosclerosis, a chronic inflammatory disease, is the major cause of life-threatening complications such as myocardial infarction and stroke. Endothelial apoptosis plays a vital role in the initiation and progression of atherosclerotic lesions. Although a subset of microRNAs (miRs) have been identified as critical regulators of atherosclerosis, studies on(More)
Heat stress is a critical threat to tall fescue in transitional and warm climate zones. Identification of association between molecular markers and heat tolerance-related functional traits would promote the efficient selection of heat tolerant tall fescue cultivars. Association analysis of heat tolerance-related traits was conducted in 100 diverse tall(More)
INTRODUCTION Atrial fibrillation (AF) is associated with impaired coronary flow by means of Thrombolysis in Myocardial Infarction (TIMI) frame count (TFC). Mean platelet volume (MPV) is elevated in patients with AF. In the present study we aimed to investigate the relationship between MPV and TFC in patients with AF in the absence of obstructive coronary(More)
The present study was designed to investigate the cardiac benefits of M₃ muscarinic receptor (M₃-mAChR) overexpression and whether these effects are related to the regulation of the inward rectifying K⁺ channel by microRNA-1 (miR-1) in a conditional overexpression mouse model. A cardiac-specific M₃-mAChR transgenic mouse model was successfully established(More)
BACKGROUND AND PURPOSE Pressure overload-induced cardiac interstitial fibrosis is viewed as a major cause of heart failure in patients with hypertension or aorta atherosclerosis. The purpose of this study was to investigate the effects and the underlying mechanisms of genistein, a natural phytoestrogen found in soy bean extract, on pressure overload-induced(More)
