We present an efficient approach for synthesizing thin graphite-coated SiO2 composites (TGCSCs) supercapacitor applications, by encapsulating particles within multilayered graphene using thermal chemical vapor deposition. The TGCSC maintains the original morphology of particles, with graphite layer exhibiting interlayer distance ∼0.34 nm. Surface analysis revealed formation Si–C and SiO–C bonds, which enhanced conductivity overall performance; in addition, acid treatment improved electrode...
Objectives: The ideal diagnostic criteria of autoimmune pancreatitis (AIP) are still challenging. Therefore, we investigated the clinical features AIP in Korea and assessed use new Korean criteria. Methods: We reviewed 67 patients with enrolled 16 hospitals via a multicenter study. diagnosis was confirmed according to that included pancreatic imaging, laboratory findings, histopathology, response steroid. Results: Mean age 56 years, 73% were men. Obstructive jaundice (52%) most common...
It remains unclear whether the currently-used normal range for serum alanine aminotransferase (ALT) levels really reflects a healthy liver. The present study was conducted to evaluate of ALT in Korean adult population and determine clinical significance unhealthy levels.We reviewed medical records, including questionnaires results laboratory radiological tests at Health Promotion Center Korea University Anam Hospital between March 2005 February 2007. written questionnaire form, included...
To suggest a new cleansing score system for small bowel preparation and to evaluate its clinical efficacy.Twenty capsule endoscopy cases were reviewed was assessed with the scoring system. For assessment, two visual parameters used: proportion of visualized mucosa degree obscuration. Representative frames from images serially selected scored at 5-min intervals. Intraclass correlation coefficient (ICC) obtained assess reliability efficacy evaluation validation, scores our compared another...
Background and Aim: Low-volume polyethylene glycol with ascorbic acid (PEG-Asc) use is reported to be as safe effective traditional 4-L use. However, PEG-Asc produces bubbles, which cause problems during colonoscopy. Data on the effects of using antifoaming agents such simethicone are lacking. The aim this CONSORT-prospective, randomized, observer-blinded, controlled trial compare quality bowel preparation compliance between users plus users. Methods: Adult outpatients aged 18 80 years...
Submucosal injection is used to prevent complications, such as perforation, during endoscopic mucosal resection (EMR). Since of normal saline produces elevation short duration, repeated needed for extensive resection. To overcome this limitation, various submucosal solutions have been developed but there are few data comparing their efficacy. This study was therefore conducted compare the physical and chemical properties duration solutions.A fresh transverse colon specimen acquired from a...
Abstract Background/Aims: Serum creatinine (Cr) is not a reliable marker for early detection of renal dysfunction in patients with cirrhotic ascites. Several reports have suggested that cystatin C (CysC) more sensitive than Cr detecting reduced function these patients. This study evaluated the clinical significance CysC ascites and normal serum level. Methods: We enrolled level (<1.2 mg/dl). Liver tests, international normalized ratio (INR) levels were measured on same day all using...
Although the Psychometric Hepatic Encephalopathy Score (PHES) for diagnosis of minimal hepatic encephalopathy (MHE) has been validated in several countries, further validation is required its use different populations. The aims this study were thus to standardize PHES a healthy Korean population and evaluate prevalence MHE among patients with liver cirrhosis.Two-hundred subjects without evidence disease 160 cirrhosis overt HE included. Blood sampling routine laboratory tests determination...
AIM:To investigate whether suspected blood indicator (SBI) in capsule endoscopy (CE) is affected by background color and passage velocity. METHODS:Experimental models of the small intestine constructed from paper a variety colors were used to simulate observed CE images.The studied included very pale yellow, magenta, light grayish pink, burnt sienna, deep dark brown, red spots attached inside them.An endoscopic was manually passed through models.The rate detection SBI evaluated based on...

AIM:To evaluate the value of systemic inflammationbased markers as prognostic factors for advanced pancreatic cancer (PC). METHODS:Data from 82 patients who underwent combination chemotherapy with gemcitabine and erlotinib PC 2011 to 2014 were collected retrospectively.Data that included neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio, C-reactive protein (CRP)-to-albumin (CRP/Alb) analyzed.Kaplan-Meier curves, univariate multivariate Cox proportional hazards regression...
Background/Aims Hepatitis C virus (HCV) RNA testing can be performed using qualitative or quantitative assays, and it is still unclear which more useful as a primary test in patients positive for anti-HCV. The present study evaluated the usefulness of anti-HCV signal-to-cutoff ratio (S/CO ratio) predicting HCV results. Methods Patients on whom was due to enzyme immunoassay were enrolled. divided into viremia no-viremia groups according Receiver-operating characteristic (ROC) curve analysis...
It is still uncertain whether the accuracy of transient elastography (TE) in predicting fibrosis stage similar chronic hepatitis B (CHB) and C (CHC). The present study was carried out to evaluate underlying cause viral affects predictive TE.Patients with CHB or CHC who were admitted for a liver biopsy enrolled. Patients underwent TE laboratory tests on same day as biopsy. analyzed by comparing areas under receiver-operating characteristic curves (AUCs).Two-hundred seven patients enrolled,...
Background/Aims Several studies suggested that serum cystatin C (CysC) is more useful than creatinine (Cr) for the assessment of renal function in patients with liver cirrhosis. This study evaluated clinical significance CysC cirrhotic ascites and normal Cr level. Methods We enrolled a level (<1.2 mg/dL). GFR was measured by 99mTc-DTPA scan. Serum Cr, CysC, clearance (CCr) were on same day. Significant impairment severe defined as <60 mL/min <30 mL/min, respectively. Results Eighty-nine (63...
