BACKGROUND We investigated the myocardial protective effect of a moderate-potassium cold blood cardioplegic solution (K+, 10 mmol/L) in pediatric cardiac surgery. METHODS Sixty-eight pediatric patients with congenital heart disease and undergoing open heart surgery with cardiopulmonary bypass were randomly allocated to the high potassium (HP [K+, 20(More)
The calcium paradox represents an important model in which to study myocardial injuries due to intracellular Ca(2+) overload. In a previous study, calpain was transiently activated in Ca(2+) -paradoxic hearts. The aim of the present study was to determine the role of calpain in myocardial dysfunction in hearts subjected to the Ca(2+) paradox and to(More)
The effects of sevoflurane inhalation during cardiopulmonary bypass (CPB) on postoperative courses and serum cardiac troponin I (cTnI) concentrations in pediatric patients undergoing cardiac surgery have not been extensively investigated. In this single-center, prospective, randomized trial, an anesthetic regimen containing 2% sevoflurane used throughout(More)
PURPOSE Molecular hydrogen has been used as an antioxidant to treat many diseases in clinical and animal studies. However, the therapeutic mechanism of molecular hydrogen remains unclear. We previously reported mitigation of light-induced damage in the rat retina by intraperitoneal injection of hydrogen-rich saline (HRS). In the present study, we(More)
2,3,5,4′-Tetrahydroxystilbene-2-O-β-D-glucoside (TSG) is a water-soluble active component extracted from Polygonum multiflorum Thunb. A number of studies demonstrate that TSG exerts cardioprotective effects. Since endoplasmic reticulum (ER) stress plays a key role in myocardial ischemia/reperfusion (MI/R)-induced cell apoptosis, we sought to determine(More)
Aim:Berberine (BBR), an isoquinoline-derived alkaloid isolated from Rhizoma coptidis, exerts cardioprotective effects. Because endoplasmic reticulum (ER) stress plays a pivotal role in myocardial ischemia/reperfusion (MI/R)-induced apoptosis, it was interesting to examine whether the protective effects of BBR resulted from modulating ER stress levels during(More)
The present study was aimed to investigate the underlying mechanisms of the protective effect of proanthocyanidin (Pro) against hypoxia/reoxygenation (H/R) injury in H9C2 cells with a focus on Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) signaling pathway. H9C2 cells were randomly assigned to 5 groups, including the control(More)
BACKGROUND Numerous studies have investigated association of OGG1 Ser326Cys polymorphism with lung cancer susceptibility; however, the findings are inconsistent. Therefore, we performed a meta-analysis based on 27 publications encompass 9663 cases and 11348 controls to comprehensively evaluate such associations. METHODS We searched publications from(More)
OBJECTIVES We sought to evaluate a moderate-potassium cardioplegic solution using adenosine and lidocaine as the arresting and protecting cardioprotective combination in pediatric cardiac surgery. METHODS One hundred thirty-four patients with congenital heart disease were randomly allocated to one of 3 groups according to the cardioplegia formula used:(More)
