Fat tissue produces a variety of secreted proteins (adipocytokines) with important roles in metabolism. We isolated newly identified adipocytokine, visfatin, that is highly enriched the visceral fat both humans and mice whose expression level plasma increases during development obesity. Visfatin corresponds to protein previously as pre–B cell colony-enhancing factor (PBEF), 52-kilodalton cytokine expressed lymphocytes. exerted insulin-mimetic effects cultured cells lowered glucose levels...

A max-plus linear (MPL) representation for describing the behavior of a repetitious execution system with MIMO-FIFO structure is proposed. conventional MPL form required to recalculate matrices by each job when applied systems whose processing times differ job. Approximately twice calculation volume obtain earliest and latest using compared our proposed representation. This work assigns state variables events other than ones, reduces number independent parameters in matrices, improves...

Colorectal endoscopic submucosal dissection (ESD) is used for the treatment of large colorectal superficial neoplasms. However, there have been no studies on electrocoagulation syndrome developing after ESD. The aim this study was to clarify incidence and clinical risk factors post-ESD (PECS).A total 692 patients (median age: 70 years; 395 men) with lesions, who underwent ESD at a tertiary cancer center between July 2010 December 2015, were eligible. PECS clinically diagnosed based presence...

Abstract A 69-year-old man undergoing long-term administration of a proton-pump inhibitor (PPI) underwent upper endoscopy, which found small, whitish, flat lesion in the fundic gland (oxyntic) mucosa. The patient had never received treatment for Helicobacter pylori ( Hp ) infection, and diagnostic testing was negative, suggesting an -naïve status. Two years later, appeared markedly enlarged endoscopically resected. Histological examination revealed low-grade foveolar-type gastric adenoma...

Background: With the widespread use of endoscopic submucosal dissection (ESD), more large early gastric cancers (EGC) have become candidates for resection. A precise diagnosis extent cancer is indispensable to obtain R0 The aim present study was clarify factors related lateral margin positivity in specimens resected by ESD EGC. Methods: Among 1549 EGC treated during September 2002 December 2008, lesions that were an en‐bloc fashion and resulted a pathological positive (LM+) cancer,...

Pathologic evidence of biliary diseases can be obtained from cytology in addition to endoscopic retrograde cholangiopancreatography (ERCP); however, the diagnostic effectiveness is not satisfactory.This retrospective, single-center study evaluated efficacy various sampling methods for cytologic diagnosis bile duct cancer.Biliary samples included that was simply aspirated, brush smear, brush-rinsed saline, and post-brushing lavage fluid. A set compared 76 patients with surgically proven...
