BACKGROUND People who have come close to death may report an unusual experience known as a near-death experience (NDE). This study aims to investigate NDEs and their aftereffects in dialysis patients. STUDY DESIGN Cross-sectional study. SETTING & PARTICIPANTS 710 dialysis patients at 7 centers in Taipei, Taiwan. PREDICTOR Demographic characteristics,(More)
Increased hepatic sympathetic activity affects hepatic metabolism and hemodynamics and subsequently causes acute hepatic injury. We examined whether the vesicovascular reflex evoked by bladder overdistension could affect hepatic function, specifically reactive oxygen species (ROS)-induced inflammation and apoptosis, through activation of the hepatic(More)
A major complication in continuous, ambulatory peritoneal dialysis in patients with end-stage renal disease who are undergoing long-term peritoneal dialysis (PD) is peritoneal fibrosis, which can result in peritoneal structural changes and functional ultrafiltration failure. Human umbilical mesenchymal stem cells (HUMSCs) in Wharton's jelly possess stem(More)
BACKGROUND Increased oxidative stress in end-stage renal disease (ESRD) patients may oxidize macromolecules and consequently lead to cardiovascular events during chronic hemodialysis. Electrolyzed reduced water (ERW) with reactive oxygen species (ROS) scavenging ability may have a potential effect on reduction of hemodialysis-induced oxidative stress in(More)
AIMS Repetitive hypoxic preconditioning (RHP) may provide more efficient protection than single hypoxic preconditioning against renal ischemia/reperfusion-induced injury via hypoxia-induced factor 1alpha (HIF-1alpha)-dependent heat shock protein 70 (HSP70) pathways. MAIN METHODS Wistar rats were subjected to intermittent hypoxic exposure (15h/day),(More)
OBJECTIVE We compared the effects of modified progressive thermal preconditioning (PTP) and whole-body thermal preconditioning (TP) on stress responses, oxidative stress biomarkers, and arterial thrombosis formation, and explored their possible actions through phosphatidylinositol 3-kinase (PI3K)/Akt-dependent heat-shock protein (Hsp)/endothelial nitric(More)
N-methyl-d-aspartate (NMDA) receptor activated by glutamate/glycine is located in the kidneys. The NMDA receptor subunit NR1 is increased in damaged renal tissue. This study explored the role of NMDA receptors in ischemia-reperfusion-induced renal dysfunction in rats. With Western blot analysis and renal functional assay, NMDA receptor expression was(More)
Ischemia/reperfusion (I/R) may through overt H₂O₂-induced pathophysiologic mechanisms lead to renal dysfunction. We explore whether catalase (CAT) protein overexpression by adenoviral CAT gene (Adv-CAT) transfection may improve ischemia/reperfusion-induced renal dysfunction. We augmented renal CAT expression by intrarenal arterial Adv-CAT administration(More)
BACKGROUND In response to ischemic/hypoxic preconditioning, tissues/organs exhibit protective responses to subsequent and severe ischemic stress. We hypothesized that repetitive hypoxic preconditioning (RHP) may provide long-lasting protection than single preconditioning against ischemia/reperfusion injury in rat kidneys through hypoxia-induced factor(More)
BACKGROUND Oxidative stress increases in patients with end-stage renal disease and exaggerates the related comorbidities. OBJECTIVE The aim of the study was to evaluate the effects of supplementation with decaffeinated green tea extract (catechins) on hemodialysis-induced reactive oxygen species, atherosclerotic disease risk factors, and proinflammatory(More)
