Dear Editor,Plant tissue culture involves callus formation and de novo shoot ***,explants from differentiated tissues are used to generate a pluripotent cell mass,called callus,on auxin-rich callus-inducing medium(CIM),followed by shoot regeneration on cytokinin-rich shoot-inducing medium(SiM).Callus results from division of pericycle-like cells(Atta et al.,2009;Sugimoto et al.,2010);its cellular identity resembles that of lateral root primordia(Atta et al.,2009;Sugimoto et al.,2010).Callus acquires cellular pluripotency by forming root stem cell niches on CIM(Sugimoto et al.,2010)。

为了检测黑线姬鼠两亚种(来自中国东北地区、俄罗斯远东地区的东北亚种和朝鲜半岛的朝鲜亚种)线粒体DNA的变异水平并确定朝鲜亚种的分类地位,我们测序分析了两亚种的线粒体DNA细胞色素b的部分序列(1 054 bp)和控制区的部分序列(860 bp),并与基因库中黑线姬鼠相应的单倍型序列进行了比较。可以看出东北亚种的序列显示出某些分异,可以被分为2或3个亚群,所以我们提出需要更多标本的DNA分析来确定东北亚种的分类地位。另外,来自韩国的朝鲜亚种的序列,与来自中国东北地区龙江和哈尔滨的东北亚种的两个亚群相似(1个亚群是细胞色素b的两个单倍型,另1个是控制区的两个单倍型),表明基于线粒体DNA序列的遗传多样性与现今基于形态特征对这些姬鼠的分类所得结果是不一致的。因此我们认为来自韩国的朝鲜亚种是一个只在形态特异上不同于东北亚种的地方亚种,我们建议通过其他DNA标记来进一步验证其亚种地位。我们还认为朝鲜半岛不是最近的冰川期黑线姬鼠残遗种的保护区。

Toothpick impaction with sigmoid colon pseudodiverticulum formation successfully treated with colonoscopy

Foreign bodies in the colon are encountered with increasing frequency, but only sporadic reports concerning their management have appeared in the literature. While most ingested foreign bodies usually pass through the gastrointestinal tract uneventfully, sharp foreign bodies such as toothpicks infrequently cause intestinal perforation and may even result in death. We report our experience with a patient with a sigmoid colon pseudodiverticulum formation, a complication of accidental ingestion of a toothpick that was diagnosed and successfully managed colonoscopically.

Gastric inverted hyperplastic polyp: A rare cause of iron deficiency anemia

World Journal of Gastroenterology 2016年第15期22卷 4066-4070页

作者： Jin Tak Yun Seung Woo Lee Dong Pil Kim Seung Hwa Choi Seok-Hwan Kim Jun Kyu Park sun hee Jang Yun Jung Park Ye Gyu sung Hae Jung Sul Division of Gastroenterology Department of Internal Medicine College of Medicine Daejeon St. Mary’s Hospital The Catholic University of Korea Department of Pathology College of Medicine Daejeon St. Mary’s Hospital The Catholic University of Korea

Gastric inverted hyperplastic polyp(IHP) is a rare gastric polyp characterized by the downward growth of hyperplastic mucosal components into the submucosal layer. Macroscopically, a gastric IHP resembles a subepithelial tumor(SET); as a result, accurately diagnosing gastric IHP is difficult. This issue has clinical significance because gastric IHP can be misdiagnosed as SET or as malignant neoplasm In addition, adenocarcinoma can accompany benign gastric IHP. Although in most cases, gastric IHPs are asymptomatic and are found incidentally, these polyps may cause anemia secondary to chronic bleeding. Here, we report one case involving gastric IHP accompanied by chronic iron deficiency anemia that was successfully managed using endoscopic submucosal dissection.

Objective： To investigate the cytoprotective effects of Saeng-kankunbi-tang（生肝健脾汤, SKT）, a herbal prescription consisting of Artemisia capillaris and Alisma canaliculatum, and its underlying mechanism involved. Methods： In mice, blood biochemistry and histopathology were assessed in carbon tetrachloride（CCl4）-induced oxidative hepatic injury in vivo. The animal groups included vehicle-treated control, CCl4, SKT 500 mg/（kg·day） CCl4＋SKT 200 or 500 mg/（kg·day）. In Hep G2 cell, tert-butyl hydroperoxide（t BHP） induced severe oxidative stress and mitochondrial dysfunction in vitro. The cyto-protective effects of SKT were determined by 3-（4,5-dimethylthiazol）-2,5-diphenyltetrazolium bromide（MTT） assay, fluorescence activated cell sorting analysis and western blotting. Results： The administration of SKT prevented liver damage induced by CCl4 in mice, by inhibition of hepatocyte degeneration and inflammatory cell infiltration as well as plasma parameters such as alanine aminotransferase（P〈0.01）. Moreover, treatment with t BHP induced hepatocyte death and cellular reactive oxygen species production in hepatocyte cell line. However, SKT pretreatment（30–300 μg/m L） reduced this cell death and oxidative stress（P〈0.01）. More importantly, SKT inhibited the ability of t BHP to induce changes in mitochondrial membrane transition in cell stained with rhodamine 123（P〈0.01）. Furthermore, treatment with SKT induced extracellular signal-regulated kinases-mediated nuclear factor erythroid-2-related factor 2（Nrf2） activation as well as the expressions of heme oxygenase 1 and glutamate-cystein ligase catalytic, Nrf2 target genes. Conclusion： SKT has the ability to protect hepatocyte against oxidative stress and mitochondrial damage mediated by Nrf2 activation.

Charge transfer in graphene/polymer interfaces for CO2 detection

Understanding charge transfer processes between graphene and functional materials is crucial from the perspectives of fundamental sciences and potential applications, including electronic devices, photonic devices, and sensors. In this study, we present the charge transfer behavior of graphene and amine-rich polyethyleneimine （PEI） upon CO2 exposure, which was significantly improved after introduction of hygroscopic polyethylene glycol （PEG） in humid air. By blending PEI and PEG, the number of protonated amine groups in PEI was remarkably increased in the presence of water molecules, leading to a strong electron doping effect on graphene. The presence of CO2 gas resulted in a large change in the resistance of PEI/PEG-co-functionalized graphene because of the dramatic reduction of said doping effect, reaching a maximum sensitivity of 32% at 5,000 ppm CO2 and an applied bias of 0.1 V in air with 60% relative humidity at room temperature. This charge transfer correlation will facilitate the development of portable graphene-based sensors for real-time gas detection and the extension of the applications of graphene-based electronic and photonic devices.
