OBJECTIVES Our goal was to evaluate the role of myocardial nicotinamide adenine dinucleotide phosphate (NADPH) oxidase activity and plasma markers of oxidative stress in the pathogenesis of post-operative atrial fibrillation (AF). BACKGROUND Atrial fibrillation is a common complication of cardiac surgery, leading to increased morbidity and prolonged(More)
The changes in process performance and microbial communities under free cyanide (CN(-)) were investigated in a lab-scale activated sludge process treating industrial wastewater. The performance of phenol degradation did not appear to be adversely affected by increases in CN(-) concentrations. In contrast, CN(-) was found to have an inhibitory effect on(More)
A 27-year-old, right-hand-dominant woman with a posttraumatic anterior shoulder dislocation 3 months earlier after traffic accident presented because of pain and limited range of motion in the right shoulder. On physical examination, the patient had negative instability tests and a sulcus sign. On arthroscopic examination, a bifurcate long biceps tendon(More)
Changes in process performance and the nitrifying bacterial community associated with an increase of thiocyanate (SCN-) loading were investigated in a pre-denitrification process treating industrial wastewater. The increased SCN- loading led to the concentration of total nitrogen (TN) in the final effluent, but increasing the internal recycling ratio as an(More)
OBJECTIVES The purpose of this study was to investigate the phenomenon of left ventricular (LV) dysfunction after ultraendurance exercise. BACKGROUND Subclinical LV dysfunction in response to endurance exercise up to 24 h duration has been described, but its mechanism remains elusive. METHODS We tested 86 athletes before and after the Adrenalin Rush(More)
To improve the efficiency of total nitrogen (TN) removal, solid retention time (SRT) and internal recycling ratio controls were selected as operating parameters in a full-scale activated sludge process treating high strength industrial wastewater. Increased biomass concentration via SRT control enhanced TN removal. Also, decreasing the internal recycling(More)
The goal of this study was to investigate the bacterial community in activated sludge with an anaerobic side-stream reactor (ASSR), a process permitting significant decrease in sludge production during wastewater treatment. The study operated five activated sludge systems with different sludge treatment schemes serving as various controls for the activated(More)
PURPOSE This study evaluated the clinical presentations of Staphylococcus epidermidis (S. epidermidis) septic arthritis after arthroscopic anterior cruciate ligament reconstruction (ACLR). MATERIALS AND METHODS Between September 2006 and February 2008, S. epidermidis septic arthritis developed in six patients following arthroscopic ACLR. We reviewed the(More)
The goal of this study was to investigate the influences of gradually mixotrophic culture conditions on microalgal biomass and lipid production by a consortium of indigenous microalgae and bacteria present in raw municipal wastewater. Lab-scale photobioreactors containing the consortium were operated in repeated batch mode. Initial cultivation (phase I) was(More)
A lab-scale serial anoxic-aerobic reactor for the pre-denitrification process was continuously operated to efficiently and economically treat actual cokes wastewater containing various pollutants, such as phenol, ammonia, thiocyanate and cyanide compounds. The biodegradation efficiencies of the pollutants were examined by changing hydraulic retention time(More)
