The role of exercise training on hemodynamic parameters, blood lipid profiles, inflammatory cytokines, cholinesterase-positive nerves and muscarinic cholinergic (M(2)) receptors expression in the heart was investigated in Sprague-Dawley male rats with hyperlipidemia (HL). The rats were subjected to a high-fat diet and exercise training for 8 weeks, and then(More)
Apoptosis of cardiomyocytes plays an important role in the development of cardiovascular diseases (CVD). Numerous studies have shown that generation of reactive oxygen species (ROS) induced by the renin-angiotensin system (RAS) is involved in this pathological process. Recent studies also suggested that acetylcholine (ACh) prevented the hypoxia-induced(More)
It has been demonstrated that the number and differentiating potential of bone marrow mesenchymal stem cells (MSCs) decrease with age. Therefore, the search for alternative sources of MSCs is of significant value. In the present study, MSCs were isolated from umbilical cord blood (UCB) by combining gradient density centrifugation with plastic adherence.(More)
AIM To investigate the mechanism and regulation of differentiation from bone marrow mesenchymal stem cells (MSCs) into hepatocytes and to find a new source of cell types for therapies of hepatic diseases. METHODS MSCs were isolated by combining gradient density centrifugation with plastic adherence. The cells were cultured in osteogenic or adipogenic(More)
AIM To investigate the differentiation of human umbilical cord blood (HUCB)-derived mesenchymal stem cells (MSCs) into hepatocytes by induction of fibroblast growth factor-4 (FGF-4) and hepatocyte growth factor (HGF), and to find a new source of cell types for therapies of hepatic diseases. METHODS MSCs were isolated by combining gradient density(More)
Recent findings have reported that up-regulation of tumor necrosis factor-alpha (TNF-α) induced by myocardial hypoxia aggravates cardiomyocyte injury. Acetylcholine (ACh), the principle vagal neurotransmitter, protects cardiomyocytes against hypoxia by inhibiting apoptosis. However, it is still unclear whether ACh regulates TNF-α production in(More)
AIM To observe the expression changes of tumor necrosis factor alpha (TNF-α) and interleukin-10 (IL-10) during the developing process of pressure overload-induced myocardial remodeling in rats, and investigate the dynamic correlation between TNF-α and left ventricular mass index (LVMI) as well as myocardial collagen volume fraction (CVF). METHODS The rats(More)
1. Obesity is a significant challenge in terms of public health and preventive medicine. Inhibition of pre-adipocyte proliferation is believed to be important in the proposed anti-obesity mechanism. The aim of the present study was to examine the interplay between Cl(-) channels and their possible involvement in the proliferation of undifferentiated human(More)
Previous findings have shown that acetylcholine (ACh) decreased hypoxia-induced tumor necrosis factor alpha (TNF α) production, thus protected against cardiomyocyte injury. However, whether and how ACh affects TNF α-induced endoplasmic reticulum (ER) stress and cell apoptosis remain poorly defined. This study was aimed at determining the effect of ACh in(More)
BACKGROUND Excessive activation of matrix metalloproteinase 9 (MMP-9) has been found in several inflammatory diseases. Previous studies have shown that acetylcholine (ACh) reduced the levels of pro-inflammatory cytokines and decreased tissue damage. Therefore, this study was designed to explore the potential effects and mechanisms of ACh on MMP-9 production(More)
