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)
BACKGROUND Morning serum cortisol examinations and short corticotropin (ACTH) tests are popular screening tests for unstressed patients suspected of having adrenal insufficiency. However, the correlation between morning serum cortisol and the peak cortisol response in the short ACTH test after intravenous injection of ACTH has not been studied before. This(More)
BACKGROUND To assess the influence of diabetes mellitus (DM), glycemic control, and diabetes-related comorbidities on manifestations and outcome of treatment of pulmonary tuberculosis (TB). METHODOLOGY/PRINCIPAL FINDINGS Culture positive pulmonary TB patients notified to health authorities in three hospitals in Taiwan from 2005-2010 were investigated.(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)
We report an unusual case of primary hypothalamic lymphoma with hypopituitarism presenting as Stiff-man syndrome (SMS). A 64-year-old man was hospitalized due to a 3-week history of general weakness, anorexia, vomiting, weight loss, and muscle pain and spasms precipitated by motion and tactile stimuli resulting in muscle stiffness and difficulty in(More)
A total of 1076 patients with thyroid nodules were reviewed. The accuracy of fine needle aspiration biopsy (FNAB) and frozen section (FS) were compared and clinical risk factors were analyzed. Our results indicate that 67.9% are benign and 32.1% are malignant with the predominance of papillary thyroid cancer (75.1%). Overall diagnostic accuracy for FNAB and(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)
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)
BACKGROUND Diabetes and hypertension have significant effects on cardiac calcium (Ca(2+)) regulation, which plays an essential role in determining cardiac function. The effect of peroxisome proliferator-activated receptor (PPAR)-γ agonists on Ca(2+) regulation in the cardiomyocytes is unclear. OBJECTIVE The purpose of this study was to investigate the(More)
