OBJECTIVE Postoperative cognitive dysfunction (POCD) commonly develops after cardiac surgery affecting patients' outcome. Cerebral oximetry noninvasively measures regional cerebral oxygen saturation (rSO(2)) and significant correlation has been reported between intraoperative cerebral desaturation and POCD, as well as patients' outcome following coronary(More)
OBJECTIVE One-lung ventilation (OLV) is accomplished with a double-lumen tube (DLT) or a bronchial blocker (BB). The authors compared the effectiveness of lung collapse using DLT, BB, and BB with the disconnection technique. DESIGN Prospective, randomized, blind trial. SETTING A university hospital. PARTICIPANTS Fifty-two patients undergoing elective(More)
BACKGROUND To prospectively investigate the predictive value of the preoperative C-reactive protein (CRP) concentration for major postoperative complications following off-pump coronary artery bypass (OPCAB) surgery. METHODS AND RESULTS From January 2007 to December 2007, 185 consecutive patients scheduled for elective OPCAB surgery were allocated to a(More)
Analogs of vancomycin and pseudo-vancomycin with new sugar attachments in mono- and di-saccharide form have been enzymatically synthesized by glycosylation with overexpressed glycosyltransferases, β1,4-galactosyltransferase and α2,3-sialyl transferases. All four analogs, including galactose-containing derivatives (6 and 8) and galactose- and sialic(More)
OBJECTIVE Pulmonary hypertension remains a major problem during the perioperative period for surgical correction of long-standing valvular heart disease. Sildenafil citrate (INN sildenafil) is a selective phosphodiesterase type 5 inhibitor that is being increasingly recognized as a treatment modality for pulmonary hypertension. There is lack of evidence,(More)
Cystocin belongs to the class of nucleoside antibiotics from Streptomyces sp. GCA0001. Cystocin showed good activity against gram-positive bacteria, but showed less activity against the gram-negative bacteria. Cystocin exhibited about two to four folds higher activity than puromycin. Especially, cystocin shows relatively strong activity against(More)
OBJECTIVES Considering the role of inflammatory reaction on the pathogenesis of atrial fibrillation (AF), the aim of this study is to investigate perioperative risk factors of AF, as well as to validate the predictive value of high-sensitive C-reactive protein (hsCRP), and transfusion requirement following off-pump coronary bypass surgery (OPCAB) in a(More)
BACKGROUND Functional restoration of the facial expression is necessary after facial nerve resection to treat head and neck tumors. This study was conducted to evaluate the functional outcomes of patients who underwent facial nerve cable grafting immediately after tumor resection. METHODS Patients who underwent cable grafting from April 2007 to August(More)
When cultivated aerobically, Aspergillus niger hyphae produced extracellular glucoamylase, which catalyzes the saccharification of unliquified potato starch into glucose, but not when grown under anaerobic conditions. The Km and Vmax of the extracellular glucoamylase were 652.3 mg starch l-1 and 253.3 mg glucose l-1 min-1, respectively. In mixed culture of(More)
