OBJECTIVES Sarcoplasmic reticulum Ca-ATPases (SERCA2a) plays an essential role in the Ca homeostasis and cardiac functions. Tumor necrosis factor-alpha (TNF-alpha) decreases the SERCA2a, which may underlie cardiac dysfunction during sepsis and heart failure. Because the promoter region of SERCA2a contains CpG islands, gene methylation should be critical in(More)
Diabetic cardiomyopathy is a major complication of diabetes mellitus (DM). Currently, effective treatments for diabetic cardiomyopathy are limited. The pathophysiology of diabetic cardiomyopathy is complex, whereas mitochondrial dysfunction plays a vital role in the genesis of diabetic cardiomyopathy. Metabolic regulation targeting mitochondrial dysfunction(More)
Sarcoplasmic reticulum (SR) Ca(2+)-ATPase (SERCA2a) plays an essential role in Ca(2+) homeostasis and cardiac functions. The promoter region of SERCA2a has a high content of CpG islands; thus, epigenetic modification by inhibiting methylation can enhance SERCA2a expression in cardiomyocytes. Hydralazine, a drug frequently used in heart failure, is a(More)
BACKGROUND High free fatty acid with reduced glucose utilization in diabetes mellitus (DM) impairs cardiac function. Peroxisome proliferator-activated receptors (PPARs) modulate myocardial lipid and glucose homeostasis. The active 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) regulates oxidative stress and inflammation, which may play a key role in the modulation(More)
This paper describes and evaluates a Patient-Oriented education management system for diabetes using the Internet (POEM). With this system at each patient visit, the system can automatically download a patient's medical services records, prescriptions, laboratory test results and his/her patient education materials, and organize them into a series of case(More)
BACKGROUND Peroxisome proliferator-activated receptors (PPARs) play a pivotal role in myocardial lipid and glucose homeostasis. We investigated the effects of diabetes on PPAR isoforms in different cardiac regions and explored whether proinflammatory cytokines or oxidative stress modulate PPARs in diabetic hearts. MATERIALS AND METHODS Male Wistar rats(More)
PURPOSE To develop and evaluate a Web-based, patient-orientated diabetic education management (POEM) system. METHODS The POEM system has been developed to extend hospital patient education by integrating patients' medical care data into their education program components and presenting them on the Web. Since most patients are concerned about their medical(More)
BACKGROUND Receptor for advanced glycation end products (RAGE) signaling pathway plays a vital role in diabetic cardiovascular complications. Calcitriol has been shown to exert various beneficial cardiovascular effects. The purpose of this study is to determine whether calcitriol can modulate RAGE expression, and study the potential mechanisms in diabetic(More)
Hypertension and DM (diabetes mellitus) are common chronic disorders that often co-exist. DM and PPAR (peroxisome-proliferator-activated receptor)-γ agonists may directly impair heart function. However, the effects of DM and PPAR-γ agonists on hypertensive myocardium are not known. Hence the aim of the present study was to investigate whether DM and a(More)
Cardiovascular disease is the leading cause of morbidity and mortality in patients with diabetes mellitus (DM), and patients with DM frequently develop diabetic cardiomyopathy. Currently, effective treatments for diabetic cardiomyopathy are limited. Vitamin D exerts pleiotropic effects on the cardiovascular system and is associated with DM. The purpose of(More)
