1Chemokine expression in hepatocellular carcinoma versus colorectal liver metastases显示文摘AIM: To evaluate and compare the expression profiles of CXCL12 (SDF-1), CCL19 (MIP-3β), CCL20 (MIP-3α) and CCL21 (6Ckine, Exodus2) and their receptors on RNA and protein levels in hepatocellular carcinoma (HCC) versus colorectal liver metastases (CRLM) and to elucidate their impact on the carcinogenesis and progression of malignant liver diseases. METHODS: Chemokine expression was analyzed by RT-PCR and ELISA in 11 cases of HCC specimens and in 23 cases of CRLM and corresponding adjacent non- tumorous liver tissues, respectively. Expressions of their receptors CXCR4, CCR6 and CCR7 were analyzed by RT- PCR and Western blot analysis in the same cases of HCC and CRLM. RESULTS: Significant up-regulation for CCL20/CCR6 was detected in both cancer types. Moreover, CCL20 demonstrated significant overexpression in CRLM in relation to the HCC tissues. Being significantly up- regulated only in CRLM, CXCR4 displayed an aberrant expression pattern with respect to the HCC tissues. CONCLUSION: Correlation of CXCR4 expression with CRLM suggests CXCR4 as a potential predictive factor for CRLM. High level expression of CCL20 and its receptor CCR6 in HCC and CRLM with marked up- regulation of CCL20 in CRLM in relation to HCC tissues indicates involvement of the CCL20/CCR6 ligand-receptor pair in the carcinogenesis and progression of hepatic malignancies.Claudia Rubie Vilma Oliveira Frick Mathias Wagner Christina Weber Bianca Kruse Katja Kempf Jochen Knig Bettina Rau Martin Schilling 2006World Journal of Gastroenterology2006,12,41:24
2Co-expression of CDX2 and MUC2 in gastric carcinomas: Correlations with clinico-pathological parameters and prognosis显示文摘AIM: To evaluate the role of CDX2 homeobox protein as a predictor for cancer progression and prognosis as well as its correlation with MUC2 expression. CDX2 represents a transcription factor for various intestinal genes (including MUC2) and thus an important regulator of intestinal differentiation, which could previously be identified in gastric carcinomas and intestinal metaplasia.METHODS: Formalin-fixed and paraffin-embedded tissues from 190 gastric carcinoma patients were stained with monodonal antibodies recognizing CDX2 and MUC2, respectively. Immunoreactivity was evaluated semiquantitatively and statistical analyses including χ2 tests, uni- and multi-variate survival analyses were performed.RESULTS: CDX2 was mostly expressed in a nuclear or supranuclear pattern, whereas MUC2 showed an almost exclusive supranuclear reactivity. Both antigens were present in >80% of areas exhibiting intestinal metaplasia. An immunoreactivity in >5% of the tumor area was observed in 57% (CDX2) or in 21% (MUC2) of the carcinomas. The presence of both molecules did not correlate with WHO,significantly stronger vlUC2 expression in mucinous tumors). CDX2 correlated with a lower pT and pN stage in the subgroups of intestinal and stage I cancers and was associated with MUC2 positivity. A prognostic impact of CDX2 or MUC2 was not observed. CONCLUSION: CDX2 and MUC2 play an important role in the differentiation of normal, inflamed, and neoplastic gastric tissues. According to our results, loss of CDX2 may represent a marker of tumor progression in early gastric cancer and carcinomas with an intestinal phenotype.Kristina Roessler Stefan P.M(o|¨)nig Paul M.Schneider Franz-Georg Hanisch Stephanie Landsberg Juergen Thiele Arnulf H.H(o|¨)lscher Hans P.Dienes Stephan E.Baldus 2005World Journal of Gastroenterology2005,11,21:15
3Treatment of early gastric cancer in the Western World显示文摘The incidence rate of gastric cancer is much higher in Asia than in the Western industrial nations.According to the different screening programs in Japan and Korea about fifty percent of treated patients had an early tumor stage.In contrast,European and American patients with gastric cancer had an advanced tumor stage.Therefore,the experience for the various therapeutic options for gastric cancer may be different between these regions.In this review we tried to point out the treatment modalities in Western industrial countries for early gastric cancer.Elfriede Bollschweiler Felix Berlth Christoph Baltin Stefan Mnig Arnulf H Hlscher 2014World Journal of Gastroenterology2014,20,19:8

6用OH-PLIF研究浮力对预混V形火焰的作用显示文摘在火焰和流动相互作用中,浮力是火焰影响流场的因素致一。研究浮力的作用有助于深入了解湍流燃烧的机理。本文利用甲烷-空气预混V形火焰研究浮力的作用。分析表明浮力不仅影响火焰的平均位置,还可能影响火焰的皱折。在1go和μg下用OH-PLIF观测火焰,发现层流和湍流火焰呈现相反的浮力效应,这表明浮力确实影响火焰的皱折。另外,层流火焰锋面在μg下明显折皱,这意味着微重力也适于研究火焰中其他诱发流动的机制。王岳 雷宇 张培元 张孝谦 Knig J Hinrichs O Eigenbrod C 2001工程热物理学报2001,22,3:4
7Rice Drying,Storage and Processing:Effects of Post-Harvest Operations on Grain Quality显示文摘Various post-harvest processes of rice are commonly employed,especially during the off-season,to ensure its consumption feasibility,which often affect the grain quality.Different forms of drying,storage and processing of rice are evaluated to identify their effects on grain quality.Microwave drying has emerged as an alternative to the widely-used intermittent-drying and fixed-bed-dryer methods of drying paddy rice.Control of drying-air temperatures(between 40℃ and 60℃)according to the rice variety can improve quality,especially for exotic varieties.Keeping stored grain in hygroscopic balance,with water content between 11%to 15%,at temperatures between 16℃ and 20℃ and with intergranular relative humidity near 60%,allows 12 months of storage in a controlled environment without significant deterioration.Other innovations,notably the application of artificial refrigeration to grain stored in bulk in vertical cylindrical silos and the use of impermeable packaging for storage,ensure the conservation of grain mass.The different stages and equipments used to obtain polished,brown and parboiled rice result in significant changes in the nutritional value of rice because of the removal of the outermost layers of the grains.Polishing reduces the nutritional value and physical homogeneity of rice.Brown rice retains more bioactive compounds and nutrients because it does not lose the outer layer of the grains in the polishing processes.Parboiled rice,although less nutritious than brown rice,has better grain integrity and milling yield and less loss of nutrients than white rice.Amanda MÜLLER Marcela Trojahn NUNES Vanessa MALDANER Paulo Carteri CORADI Rosana Santos de MORAES Samuel MARTENS Andressa Fernandes LEAL Vladison Fogliato PEREIRA Cristielle König MARIN 2022Rice science2022,29,1:3

9Novel fiber-optical interferometer with miniaturized probe for in-hole measurements显示文摘Today, micro-system technology and the development of new MEMS (Micro-Electro-Mechanical Systems) are emerging rapidly. In order for this development to become a success in the long run, measurement systems have to ensure product quality. Most often, MEMS have to be tested by means of functionality or destructive tests. One reason for this is that there are no suitable systems or sensing probes available which can be used for the measurement of quasi inaccessible features like small holes or cavities. We present a measurement system that could be used for these kinds of measurements. The system combines a fiber optical, miniaturized sensing probe with low-coherence interferometry, so that absolute distance measurements with nanometer accuracy are possible.Robert Schmitt Tilo Pfeifer Frank Depiereux Niels Knig 2008Optoelectronics Letters2008,4,2:3

11Association of the GNAS1 T393C polymorphism with tumor stage and survival in gastric cancer显示文摘AIM:To analyze the impact of the GNAS1 T393C polymorphism on prognosis and histopathology of gastric cancer.METHODS:Genomic DNA was extracted from paraffinembedded tissues of 122 patients with primary gastric carcinoma and from the blood of 820 healthy white individuals.Allelic discrimination was performed by quantitative real-time polymerase chain reaction.Genotyping was correlated with histopathologic parameters and with overall survival according to the Kaplan-Meier approach and with multivariate analysis by multiple stepwise regression.RESULTS:Thirty-nine(32%) patients displayed a CC genotype,57(46.7%) a CT genotype and 26(21.3%) a TT genotype.The frequency of the C allele(fC) in the patient group was 0.55,which was not signif icantly different from that of healthy blood donors.The distribution was compatible with the Hardy-Weinberg equilibrium.Analysis of clinicopathological parameters did not show any signif icant correlation of the T393C genotype with gender(P=0.50),differentiation(P=0.29),pT-category(P=0.19),pN-category(P=0.30),pM-category(P=0.25),R-category(P=0.95),the classifications according to WHO(P=0.34),Laurén(P=0.16),Goseki(P=1.00) and Ming(P=0.74).Dichotomization between C+(CC+CT) and C-genotypes(TT),however,revealed signif icantly more advanced tumor stages(P=0.023) and lower survival rates(P=0.043) for C allele carriers.CONCLUSION:The present study provides strong evidence to suggest that the GNAS1 T393C allele carrier status influences tumor progression and survival in gastric cancer with higher tumor stages and a worse outcome for C allele carriers.Hakan Alakus Stefan P Mnig Ute Warnecke-Eberz Gül Alakus Günther Winde Uta Drebber Klaus J Schmitz Kurt W Schmid Kathrin Riemann Winfried Siffert Elfriede Bollschweiler Arnulf H Hlscher Ralf Metzger 2009World Journal of Gastroenterology2009,15,48:3

14论“巴布尔传”中的过去时显示文摘1、下面这篇论文是对巴布尔传中关于动词句法的论述的基本考虑。关于某些形式的有些观点可看作是假设,这些假设应在另外的论文中进一步予以证实。 到目前为止,对突厥语动词系统的“时”的解释取得的成果极小,所以我有意识地从约翰逊所阐明的关于土耳其语的体—时系统及Aktionsarten(1971)中寻求联系。约翰逊对土耳其语的现状的所有解释不仅仅是优良的,而且对突厥语族所有的语言也是适用的,这并不排除在两个方面存在变异。首先。Claus Schnig 李增祥 1989语言与翻译1989,,2:2
15Is the schatzki ring a unique esophageal entity?显示文摘AIM:To study,whether the association of Schatzki rings with other esophageal disorders support one of the theories about its etiology.METHODS:From 1987 until 2007,all patients with newly diagnosed symptomatic Schatzki rings (SRs) were prospectively registered and followed.All of them underwent structured interviews with regards to clinical symptoms,as well as endoscopic and/or radiographic examinations.Endoscopic and radiographic studies determined the presence of an SR and additional morphological abnormalities.RESULTS:One hundred and sixty-seven patients (125 male,42 female) with a mean age of 57.1±14.6 years were studied.All patients complained of intermittent dysphagia for solid food and 113 (79.6%) patients had a history of food impaction.Patients experienced symptoms for a mean of 4.7±5.2 years before diagnosis.Only in 23.4% of the 64 patients who had endoscopic and/or radiological examinations before their first presentation to our clinic,was the SR previously diagnosed.At presentation,the mean ring diameter was 13.9±4.97 mm.One hundred and sixty-two (97%) patients showed a sliding hiatal hernia.Erosive reflux esophagitis was found in 47 (28.1%) patients.Twenty-six (15.6%) of 167 patients showed single or multiple esophageal webs;five (3.0%) patients exhibited eosinophilic esophagitis;and four (2.4%) had esophageal diverticula.Four (7%) of 57 patients undergoing esophageal manometry had nonspecific esophageal motility disorders.CONCLUSION:Schatzki rings are frequently associated with additional esophageal disorders,which support the assumption of a multifactorial etiology.Despite typical symptoms,SRs might be overlooked.Michaela Müller Ines Gockel Philip Hedwig Alexander J Eckardt Kathrin Kuhr Jochem Knig Volker F Eckardt 2011World Journal of Gastroenterology2011,17,23:2

20Long-term overlap of social and genetic structure in free-ranging house mice reveals dynamic seasonal and group size effects显示文摘Associating with relatives in social groups can bring benefits such as reduced risk of aggression and increased likelihood of cooperation.Competition among relatives over limited resources,on the other hand,can induce individuals to alter their patterns of association.Population density might further affect the costs and benefits of associating with relatives by altering resource competition or by changing the structure of social groups;preventing easy association with relatives.Consequently,the overlap between genetic and social structure is expected to decrease with increasing population size,as well as during times of increased breeding activity.Here,we use multi-layer network techniques to quantify the similarity between long-term,high resolution genetic,and behavioral data from a large population of free-ranging house mice(Mus musculus domesticus),studied over 10years.We infer how the benefit of associating with genetically similar individuals might fluctuate in relation to breeding behavior and environmental conditions.We found a clear seasonal effect,with decreased overlap between social and genetic structure during summer months,characterized by high temperatures and high breeding activity.Though the effect of overall population size was relatively weak,we found a clear decrease in the overlap between genetic similarity and social associations within larger groups.As well as longer-term within-group changes,these results reveal population-wide short-term shifts in how individuals associate with relatives.Our study suggests that resource competition modifies the trade-off between the costs and benefits of interacting with relatives.Julian C.EVANS Anna K.LINDHOLM Barbara KöNIG 2021Current Zoology2021,67,1:2
