The diagnosis and treatment of recurrent gastric cancer remains difficult. aim this study was to determine the risk factors for recurrence prognosis these patients.Of 2328 patients who underwent curative resection from 1987 1995, 508 whose confirmed by clinical examination or reoperation were studied retrospectively. that determined patterns timing investigated univariate multivariate analysis.The mean time 21.8 months peritoneal most frequent (45.9 per cent). Logistic regression analysis...

Abstract Although significant progress has been made in the development of vacuum‐deposited small‐molecule organic light‐emitting diodes (OLEDs), one most desired research goals is still to produce flexible displays by low‐cost solution processing. The solution‐processed OLEDs based on small molecules could potentially be a good approach but no intensive studies this topic have conducted so far. To fabricate high‐performance devices molecules, underlying nature produced films and must...

We report efficient tandem white organic light-emitting diodes (WOLEDs) by using bathocuproine:Cs2CO3∕MoO3 as an effective interconnecting layer. utilized two primary colors of sky blue and orange fluorescent emitters to obtain electroluminescence. Although single WOLEDs adjacent emitting layers showed a maximum current efficiency 7.96cd∕A with Commission Internationale d’Eclairage (CIE) coordinates (0.28, 0.34), the WOLED device made stacking color OLEDs in series demonstrated doubled...

Background A small number of nomograms have been previously developed to predict the individual survival patients who undergo curative resection for gastric cancer. However, all were derived from single high-volume centers. The aim this study was develop and validate a nomogram cancer using multicenter database. Methods We reviewed clinicopathological data 2012 underwent between 2001 2006 at eight Among these centers, six institutions randomly assigned development set, other two centers...

Endoscopic submucosal dissection (ESD) is a novel alternative treatment for differentiated early gastric cancer (EGC) without lymph node metastasis. We conducted this study to verify the therapeutic usefulness of ESD treating EGC compared that surgery.This retrospective cohort 382 patients treated with from March 2006 May 2010. The propensity score yielded 275 matched patients. They were divided into an group 175 people and gastrectomy 100 people. patient demographics, pathologic...

Background/Aims Various pulmonary diseases may be associated with bronchial anthracofibrosis (BAF). Our aim was to identify a relationship between BAF and endobronchial tuberculosis (EBTB). Methods In total, 156 patients, diagnosed EBTB using bronchoscopy, June 1999 May 2008, were included. Clinical bronchoscopic findings patients (n = 72, group) without 84, non-BAF) analyzed retrospectively. Results The crude odds ratio (OR) of for 8.88 (95% confidence interval, 6.37 12.37). On multivariate...

There has been considerable controversy over the prognosis of mucinous gastric adenocarcinoma (MGC). In this study we analyzed clinicopathologic differences between MGC and non-mucinous carcinoma (NMGC). addition, relationship mucin content other variables, including in MGC, was also investigated. We reviewed 2118 patients with pathologically-confirmed cancer who underwent gastrectomy at Department Surgery, Yonsei University College Medicine, during period Jan. 1987 Dec. 1993. Among them,...

The long-term survival of patients who undergo surgery for stage IV gastric cancer is poor, due to metastatic spread the tumor. Intraperitoneal chemotherapy (IPT) as a possible treatment peritoneal dissemination has been investigated in number different tumors. aim this study was investigate toxicity and impact early postoperative IPT on with advanced cancer.Between 1993 1997, total 91 underwent potentially curative or palliative resection received intraperitoneal mitomycin C before closure...

A facile surface modification technique for imposing antifouling properties on ceramic microfiltration (MF) membranes was developed based the chemical conjugation of organosilane molecules ceramics. The MF (pore size: approximately 0.1 µm) were fabricated using conventional dip coating in an alumina slurry with nano-sized particles. subsequently subjected to grafting different molar concentrations (25, 50, and 100 mM). physicochemical analysis organosilane-grafted revealed a small decrease...

Background/Aims Intraoperative cholangiogram (IOC) during laparoscopic cholecystectomy (LC) has been used to evaluate bile duct stone. But, the routine use of IOC remains controversial. With LC, we reviewed variation hepatic confluence and try suggest diagnostic criteria asymptomatic common (CBD) Methods We medical record 970 consecutive patients who underwent LC with from January 1999 December 2009, retrospectively. Results Nine hundered seventy were enrolled. successful in 957 (98.7%)...

Purpose: Even with excellent surgical outcome, recurrence of early gastric cancer (EGC) after a curative resection is not declining because the incidence EGC increasing. The aim this study was to propose an appropriate treatment strategy by assessing risk factors for curatively resected cancer. Materials and Methods: Of 3662 patients who had undergone resections from 1987 1996, cases 1050 were reviewed retrospectively. Among those patients, 50 () diagnosed as having recurrent cancer, which...

The macro-scale and meso/macro-scale simulations for press forming of CFRP sheet using ABAQUS S/W were both implemented to study the influence fiber orientation on formability sheet. Hashin damage criterion was used predict failure in process. properties plain woven fabric obtained from tensile test bias extension test. experiments with rectangular punch carried out validate numerical results.

Introduction: Arterial calcification is known to be related with atherosclerosis burden and future vascular event. Obesity has been suggested as a risk factor of coronary artery calcification. In this study we investigated association between intracranial arterial body mass among stroke population. Subject Method: Between January 2008 December 2013 acute cerebral infarction patients who were hospitalized in Chung-Ang University Hospital eligible included. The brain computed tomographic...

A fracture toughness model of fibrous monolithic ceramics revealed that the major factor contributed to in was actual energy absorbed by crack propagation rather than total work fracture. The load-displacement curve and path were predicted using derived mirror image with experimental data.

Fibrous Si3N4 monolithic ceramics with a hexagonal cell were fabricated in the preferred orientation. The densified fibrous showed fracture toughness of 17 MPam1/2. An application SiC whisker as reinforcement exhibited higher (24 MPam1/2). influences fiber diameter and on these studied details.

G(Hui) is the Chinese character for hedgehog. Like thorny creature's defensive shield that protects and camouflages it from predators, Hui garment comprised of a coat aggressively reactive sharp spikes intended to symbolically ward off threatening presence others.
