Submegabase-size topologically associating domains (TAD) have been observed in high-throughput chromatin interaction data (Hi-C). However, accurate detection of TADs depends on ultra-deep sequencing and sophisticated normalization procedures. Here we propose a fast normalization-free method to decode the chromosomes (deDoc) that utilizes structural information theory. By treating Hi-C contact matrix as representation graph, deDoc partitions graph into segments with minimal entropy. We show...
Endoscopic papillectomy (EP) is reported to be a relatively safe and reliable procedure for complete resection of ampullary neoplasms. The aim this study was evaluate the therapeutic outcomes complications EP A retrospective multicenter conducted with 5 participating centers from January 2007 July 2014. total 104 patients who underwent neoplasms were reviewed retrospectively. performed by snare or without submucosal lifting lesion. mean age 60.5 ± 12.1 years, male-to-female ratio 2.0:1. En...

OBJECTIVES: For frail, elderly patients with large impacted common bile duct (CBD) stones, long-term treatment biliary stenting provides palliation. Biliary choleretic agents such as ursodeoxycholic acid (UDCA) and terpene preparations may promote CBD stone size reduction. We studied the effectiveness of combined UDCA a preparation medical for difficult-to-remove stones in older than 65 years this multicenter, prospective study. METHODS: A total 28 refractory to conventional endoscopic...
Background and study aims: Prolonged cannulation during endoscopic retrograde cholangiopancreatography (ERCP) increases risk of complications, particularly post-ERCP pancreatitis (PEP). This aimed to determine optimal timing discontinue ERCP when selective biliary (SBC) cannot be easily achieved. Patients methods: with naïve papilla who underwent between January 2021 December were analyzed. The primary outcome was for discontinuing based on success rate complication rate. Results: A total...
Powder bed fusion (PBF) is a metal additive manufacturing process known for high-dimensional accuracy and design flexibility. Spherical powders, often used in PBF, provide appropriate flowability uniform layer recoating but are limited by low yields high costs. In this research, low-cost hydrogenation-dehydrogenation (HDH) Ti-6Al-4V powder was the PBF process. To overcome its drawback of flow properties, simple dry-coating hydrophobic SiO 2 nanoparticles on surface HDH powders proposed....
The urgent need to alleviate global warming and limit the consumption of fossil fuels has prompted development rechargeable Zn–air batteries (ZABs) considering their superior energy density, safety, cost-effectiveness. However, sluggish reaction kinetics oxygen evolution (OER) unfavorable properties conventional OER catalysts (including low electrical conductivity use active site-blocking binders) hinder practically viable ZABs. Herein, we report a distinct approach for directly synthesizing...
Between endoscopic sphincterotomy (ES) alone and combined large balloon dilation (ES-LBD) groups, efficacy long-term complications, difference in biliary stone recurrence rate, risk factors of were compared.Medical records 222 patients who underwent ERCP for removal retrospectively reviewed. Patients with dilated CBD ≥11 mm follow-up longer than 6 months included.There 101 ES-LBD group 121 ES group. Mean duration was 25.0 (6-48) 13.0 (6-43) months, respectively (p=0.001). There no number...
Pancreatic neuroendocrine tumors (pNETs) are diverse diseases with different prognosis. The American Joint Committee on Cancer (AJCC) and the European Neuroendocrine Tumor Society (ENETS) introduced 2 tumor node metastasis (TNM) stages, World Health Organization (WHO) proposed WHO 2010 grading system for pNETs. Therefore, we aimed to validate prognostic relevance of these 3 systems pNETs in South Korea.The Korean Gastrointestinal created a retrospective registry 153 patients from 15...
The transpapillary endoscopic insertion of self-expandable metallic stents (SEMSs) has been widely used for the palliation unresectable malignant biliary obstruction. We attempted removal malfunctioning SEMSs. aim this study was to assess feasibility and safety SEMSs by comparing results between covered uncovered SEMSs.30 patients with a SEMS prospectively underwent an attempt at over 2-year period. Removal done therapeutic duodenoscope (ED-450XT5 or TJF-240), using rat-tooth forceps. Of 30...
This case-control study evaluated the safety and efficacy of endoscopic retrograde cholangiopancreatography (ERCP) in patients 90 years age older.From January 2005 to August 2011, 5,070 cases ERCP were performed at our institution. Of these, 43 involved older (mean age, 91.7±1.9 years). A control group 129 65.7±14.8 years) was matched by patient sex, sphincterotomy, presence choledocholithiasis using a propensity score. The patients' medical records retrospectively reviewed for comorbidity,...
Hepatic venous congestion (HVC) has not been assessed quantitatively prior to hepatectomy and its resolving mechanism fully analyzed. We devised verified a new method predict HVC, in which HVC was estimated from delineation of middle hepatic vein (MHV) tributaries computed tomography (CT) images. The predicted transferred the right lobes 20 living donors using paper scale, it compared with actual observed that occurred after parenchymal transection arterial clamping. evolution emergence...
Autoimmune chronic pancreatitis (AIP) is a very attractive disease to clinicians in terms of its dramatic response the oral steroid therapy contrast ordinary pancreatitis. In year 2002, Japan Pancreas Society published diagnostic criteria AIP, and many around world use these for diagnosis. The purpose this study was evaluate whether Japanese diagnosis AIP are adequate or not.We retrospectively analyzed clinical, radiologic, laboratory, histologic features 31 patients with who have been...
AIM:To investigate prevalence of Clonorchis sinensis in patients with gastrointestinal symptoms, and the relation infection to hepatobiliary diseases 26 hospitals Korea. METHODS:Consecutive who had been admitted Division Gastroenterology symptoms were enrolled from March April 2005.Of those diagnosed clonorchiasis, epidemiology correlation between surveyed by questionnaire. RESULTS:Of 3080 d i s e a , 3 9 6 ( 1 2 .9 % ) h c l o n r 1140 (37.2%) history eating raw freshwater fish.Of fish...
