Prognostic factors in patients with node-negative gastric carcinoma:A comparison with node-positive gastric carcinoma

引用

World Journal of Gastroenterology 2006年第8期12卷 1182-1186页

作者： Dong Yi Kim Kyeung won Seo jae Kyoon joo Young Kyu Park Seong Yeob Ryu Hyeong Rok Kim Young Jin Kim Shin Kon Kim Division of Gastroenterologic Surgery Department of SurgeryChonnam National University Medical SchoolGwangjuKorea

AIM： To identify the clinicopathological characteristics of lymph node-negative gastric carcinoma, and also to evaluate outcome indicators in the lymph node-negative patients.METHODS： Of 2848 gastric carcinoma patients, 1524 （53.5%） were lymph nede-negative. A statistical analysis was performed using the Cox model to estimate outcome indicators. RESULTS： There was a significant difference in the recurrence rate between lymph nede-negative and lymph node-positive patients （14.4% vs 41.0%, P〈0.001）. The 5-year survival rate was significantly lower in lymph node-positive than in lymph node-negative patients （31.1% vs 77.4%, P〈0.001）. Univariate analysis revealed that the following factors influenced the 5-year survival rate： patient age, tumor size, depth of invasion, tumor location, operative type, and tumor stage at initial diagnosis. The Cox proportional hazard regression model revealed that tumor size, serosal invasion, and curability were independent, statistically significant, prognostic indicators of lymph node-negative gastric carcinoma. CONCLUSION： Lymph node-negative patients have a favorable outcome attributable to high curability, but the patients with relatively large tumors and serosal invasion have a poor prognosis. Curability is one of the most reliable predictors of long-term survival for lymph nodenegative gastric carcinoma patients.

Involvement of mitochondrial Na+-Ca2+ exchange in intestinal pacemaking activity

引用

World Journal of Gastroenterology 2006年第5期12卷 796-799页

作者： Byung joo Kim jae Yeoul Jun Insuk So Ki Whan Kim Department of Physiology and Biophysics College of MedicineSeoul National UniversityRepublic of Korea Department of Physiology College of MedicineChosun UniversityRepublic of Korea

AIM： Interstitial cells of Cajal （ICCs） are the pacemaker cells that generate slow waves in the gastrointestinal （GI） tract. We have aimed to investigate the involvement of mitochondrial Na^＋-Ca^2＋ exchange in intestinal pacemaking activity in cultured interstitial cells of Cajal. METHODS： Enzymatic digestions were used to dissociate ICCs from the small intestine of a mouse. The whole-cell patch-clamp configuration was used to record membrane currents （voltage clamp） and potentials （current clamp） from cultured ICCs. RESULTS： Clonazepam and CGP37157 inhibited the pacemaking activity of ICCs in a dose-dependent manner. Clonazepam from 20 to 60 μmol/L and CGP37157 from 10 to 30 μmol/L effectively inhibited Ca^2＋ efflux from mitochondria in pacemaking activity of ICCs. The ICsos of clonazepam and CGP37157 were 37.1 and 18.2 μmol/ L, respectively. The addition of 20 μmol/L NiCl2 to the internal solution caused a ＂wax and wane＂ phenomenon of pacemaking activity of ICCs. CONCLUSION： These results suggest that mitochondria Na^＋-Ca^2＋ exchange has an important role in intestina pacemaking activity.

A novel visible-light Nd-doped CdTe photocatalyst for degradation of Reactive Red 43:Synthesis,characterization,and photocatalytic properties

引用

Journal of Rare Earths 2016年第1期34卷 45-54页

作者： Younes HANIFEHPOUR Nazanin HAMNABARD Bamin KHOMAMI Sang Woo joo Bong-Ki MIN jae Hak JUNG School of Mechanical Engineering Yeungnam University Department of Chemical and Biomolecular Engineering University of Tennessee Center for Research Facilities Yeungnam University School of Chemical Engineering Yeungnam University

Novel high-efficiency visible-light-sensitive Nd-doped CdTe nanoparticles were prepared with various doping concentra- tions of neodymium ion by a facile hydrothermal method. The reaction products were analyzed via X-ray diffraction （XRD）, scanning electron microscopy （SEM）, transmission electron microscopy （TEM）, photoelectron spectroscopy （XPS）, and UV-Vis diffuse re- flectance spectroscopy techniques. Red shift was seen in the absorption band edge peak in the UV-Vis absorbance specmun with in- creasing Nd content. The XRD and XPS results confirmed that Nd ions successfully replaced Cd atoms and were incorporated into the crystal lattice of CdTe. SEM and TEM images indicated spherical structure and high crystallinity. Even at a very low Nd/CdTe molar ratio of 2 mol.%, Nd doping could greatly enhance the photocatalytic activity of CdTe. The photocatalytic activity of Nd-doped CdTe nanoparticles was evaluated by monitoring the decolorization of RRed 43 in aqueous solution under visible-light irradiation. The color removal efficiency of Nd0.08Cd0.9eYe and pure CdTe were 83.14% and 14.32% after 100 min of treatment, respectively. Among different amounts of the doping agent, 8 tool.% Nd indicated the highest decolorization. The presence of radical scavengers such as CF, CO3-, SO4〉, and huthanol was found to reduce the decolorization efficiency.
