| 2 | Schistosoma mansoni proteins attenuate gastrointestinal motility disturbances during experimental colitis in mice显示文摘AIM:To investigate the therapeutic effect of Schistosoma mansoni(S.mansoni) soluble worm proteins on gastrointestinal motility disturbances during experimental colitis in mice. METHODS:Colitis was induced by intrarectal injection of trinitrobenzene sulphate(TNBS) and 6 h later,mice were treated ip with S.mansoni proteins.Experiments were performed 5 d after TNBS injection.Inflammationwas quantified using validated inflammation parameters. Gastric emptying and geometric center were measured to assess in vivo gastrointestinal motility.Peristaltic activity of distal colonic segments was studied in vitro using a modified Trendelenburg set-up.Cytokine profiles of T-lymphocytes isolated from the colon were determined by real time reverse transcriptase-polymerase chain reaction. RESULTS:Intracolonic injection of TNBS caused severe colitis.Treatment with S.mansoni proteins significantly ameliorated colonic inflammation after 5 d.TNBS did not affect gastric emptying but significantly decreased the geometric center and impaired colonic peristaltic activity 5 d after the induction of colitis.Treatment with S.mansoni proteins ameliorated these in vivo and in vitro motility disturbances.In addition,TNBS injection caused a downregulation of effector T cell cytokines after 5 d,whereas a S.mansoni protein effect was no longer observed at this time point. CONCLUSION:Treatment with S.mansoni proteins attenuated intestinal inflammation and ameliorated motility disturbances during murine experimental colitis. | Nathalie E Ruyssers Benedicte Y De Winter Joris G De Man Natacha D Ruyssers Ann J Van Gils Alex Loukas Mark S Pearson Joel V Weinstock Paul A Pelckmans Tom G Moreels | 2010 | World Journal of Gastroenterology2010,16,6: | 11 |

| 4 | Gamma Irradiation of Embryogenic Callus Cultures and In vitro Selection for Salt Tolerance in Sugarcane (Saccharum officinarum L.)显示文摘Radiation induced mutagenesis followed by in vitro selection was employed for salt tolerance in popular Indian sugarcane (Saccharum officinarum L.) cv. CoC-671. Embryogenic calli were gamma irradiated and exposed to different levels of NaCl (42.8,85.6,128.3,171.1,213.9,256.7,299.5,or 342.2 mM). The relative growth rate (RGR) decreased progressively with increasing salt stress and was the least with a salt stress of 256.7 mM (0.25 ± 0.009),almost 10 fold lesser than the control. The RGR was significantly lower in 85.6 mM and higher salt stressed calli than the control. The survival percent also decreased,with an increase in NaCl concentration. In case of 10 and 20 Gy irradiated calli,regeneration was observed up to 85.6 mM NaCl selection,medium,whereas,higher treatments (128.3 mM and beyond) exhibited browning initially. However,in the subsequent subcultures,regeneration was obtained in the case of 10 and 20 Gy irradiated calli on 128.3 and 171.1 mM NaCl selections. Higher dose of gamma irradiation (40 Gy) also showed regeneration,but only with 85.6 mM NaCl selection. The unirradiated calli regenerated the highest number of plantlets followed by 10 and 20 Gy irradiated calli on salt selection. A total of 147 plantlets were selected from different salt levels. The salt selected plants are being tested for their field performance. | Vikas Y Patade P Suprasanna V A Bapat | 2008 | Agricultural Sciences in China2008,7,9: | 6 |
| 5 | 通过手术导致的重量损失由胃绕过在疾病的肥胖的病人改进非含酒精的脂肪肝疾病显示文摘 AIM:To evaluate the effects of surgical weight loss(Roux-en-Y gastric bypass with a modified Fobi-Capella technique) on non alcoholic fatty liver disease in obese patients.METHODS:A group of 26 morbidly obese patients aged 45 ± 2 years and with a body mass index > 40 kg/m 2 who underwent open surgical weight loss operations had paired liver biopsies,the first at surgery and the second after 16 ± 3 mo of weight loss.Biopsies were evaluated and compared in a blinded fashion.The presence of metabolic syndrome,anthropometric and biochemical variables were also assessed at baseline and at the time of the second biopsy.RESULTS:Percentage of excess weight loss was 72.1% ± 6.6%.There was a reduction in prevalence of metabolic syndrome from 57.7%(15 patients) to 7.7%(2 patients)(P < 0.001).Any significance difference was observed in aspartate aminotransferase or alanine aminotransferase between pre and postsurgery.There were improvements in steatosis(P < 0.001),lobular(P < 0.001) and portal(P < 0.05) inflammation and fibrosis(P < 0.001) at the second biopsy.There were 25(96.1%) patients with non alcoholic steatohepatitis(NASH) in their index biopsy and only four(15.3%) of the repeat biopsies fulfilled the criteria for NASH.The persistence of fibrosis(F > 1) was present in five patients at second biopsy.Steatosis and fibrosis at surgery were predictors of significant fibrosis postsurgery.CONCLUSION:Restrictive mildly malabsorptive surgery provides significant weight loss,resolution of metabolic syndrome and associated abnormal liver histological features in most obese patients. | Víctor Vargas Helena Allende Albert Lecube Maria Teresa Salcedo Juan A Baena-Fustegueras José M Fort Joaquín Rivero Roser Ferrer Roberto Catalán Eva Pardina Santiago Ramón y Cajal Jaime Guardia Julia Peinado-Onsurbe | 2012 | World Journal of Hepatology2012,4,12: | 6 |

| 7 | Left atrial appendage occluder implantation for stroke prevention in elderly patients with atrial fibrillation: acute and long-term results显示文摘Atrial fibrillation (AF) is the most common cardiac ar-rhythmia in clinical practice with an increasing incidenceand prevalence. With ageing, the risk of thromboembolicand hemorrhagic events increases dramatically. As it hasbeen reported previously, 3-year survival rate among pa-tients with AF over 75 years of age after stroke is less than50%, and almost 90% of those patients will remain dis-abled. | Karapet V Davtyan Andrey A Kalemberg Arpi H Topchyan Georgiy Y Simonyan Ekaterina V Bazaeva Victoria S Shatahtsyan | 2017 | Journal of Geriatric Cardiology2017,14,9: | 4 |
| 8 | Study of oxidative desulphurization process of coal with different metamorphism degrees显示文摘The oxidative desulphurization process of coal with different metamorphism degrees treated by an air-steam mixture has been studied.It has been shown that the pyrite present in black coal and anthracite is oxidized with the sulphur dioxide formation,and the process chemical mechanism does not depend on the quality of organic matter.The medium-metamorphized coal,capable of turning into a plastic state and cake in the range of investigated temperatures(350~450 ℃),is desulphurized with the greatest difficulty.The chemical mechanism dealing with the transformations of pyritic sulphur present in brown coal differs from similar processes taking place in black coal and anthracite,because FeS2 is converted with hydrogen sulphide formation at desulphurization. | S PYSHYEV V GUNKA Y PRYSIAZHNYI K SHEVCHUK A PATTEK-JANCZYK | 2012 | 燃料化学学报2012,40,2: | 4 |
| 9 | 厚壁奥氏体焊缝超声波检测之探究(英文)显示文摘由于奥氏体焊缝中材料性能的各向异性和微观组织结构的不同,奥氏体焊缝的超声波检测是非常困难的。超声波在奥氏体焊缝中会沿金属结晶方向发生偏转,并在焊缝边界上发生散射。过去十年来,人们开发了多种模拟各向异性材料中声波传播的仿真工具。本文则以常规超声波检测方法为基础,将声线跟踪法和弹性动力学有限积分技术(EFIT)相结合,应用于含晶间应力腐蚀裂纹的厚壁奥氏体焊缝中,其结果显示声线跟踪法和弹性动力学有限积分技术(EFIT)结合应用,有助于超声波检测参数的选取。 | Han T Y Khler B Schmitz V Zimmer A Langenberg K J | 2009 | 无损检测2009,31,11: | 3 |
| 10 | Association of the level of heteroplasmy of the 15059G>A mutation in the MT-CYB mitochondrial gene with essential hypertension显示文摘AIM: To examine whether the heteroplasmy level for 15059G>A mutation in the mitochondrial genome might be associated with essential hypertension. METHODS: This cross-sectional study involved 196 unrelated participants randomly selected from general population (90 males and 106 females) who underwent a regular medical check-up at the Institute for Ath-erosclerosis Research (Moscow, Russia). One hundred and twenty of them (61%) had essential hypertension, and 76 (39%) were apparently healthy normotensive persons. The level of heteroplasmy for 15059G>A mutation occurring in the coding region of cytochrome b gene (MT-CYB) of mtDNA isolated from the blood leukocytes, was quantified using DNA pyrosequencing method. RESULTS: The 15059G>A heteroplasmy level ranged between 4% and 83%, with a median level of 31%. Between the upper and lower quartiles of 15059G>A heteroplasmy distribution, significant differences were observed for patients' age, systolic blood pressure, and triglyceride levels. 15059G>A heteroplasmy correlated both with age (r = 0.331, P < 0.001) and the presence of hypertension (r = 0.228, P = 0.002). Regression analysis revealed that the age explains 12% variability of 15059G>A heteroplasmy, and hypertension independently explains more 5% variability. The 15059G>A heteroplasmy exceeding 31% was found to be significantly associated with a higher risk of essential hypertension (odds ratio 2.76; P (Fisher) 0.019]. The study participants with high 15059G>A heteroplasmy level were found to have significantly higher age (P < 0.001) and the prevalence of essential hypertension (P = 0.033), as compared to those with low 15059G>A heteroplasmy level. These observations suggested a positive correlation between the level of 15059G>A heteroplasmy and essential hypertension. CONCLUSION: This study provides the evidence of association of mtDNA 15059G>A mutation heteroplasmy with essential hypertension. | Igor A Sobenin Dimitry A Chistiakov Margarita A Sazonova Maria M Ivanova Yuri V Bobryshev Alexander N Orekhov Anton Y Postnov | 2013 | World Journal of Cardiology2013,5,5: | 3 |
| 11 | 掺碲硒化镓晶体的光学性能(英文)显示文摘采用水平区熔法生长了碲(Te)掺杂浓度(质量百分比)分别为0.05%,0.1%,0.5%,1%,2%的硒化镓(GaSe)晶体,并分别对掺杂浓度为0.01%,0.07%,0.38%,0.67%,2.07%的GaSe∶Te晶体的光学性能进行了表征。首次研究了GaSe∶Te晶体中刚性层声子模式的转换。吸收光谱测试结果表明:当Te掺杂浓度小于0.38%时,振动中心位于0.59 THz附近的E'(2)刚性模式吸收峰强度可达最大值,这一过程与GaSe∶Te晶体光学性能的提高密切相关。但Te掺杂浓度的进一步提高会导致E'(2)刚性模式吸收峰强度逐渐减弱,当Te掺杂浓度为1%时,E'(2)刚性模式吸收峰基本消失。这两个过程与GaSe∶Te晶体光学质量的下降密切相关。因此,E'(2)刚性模式吸收强度达到最高时对应的掺杂浓度即是GaSe∶Te晶体中Te的最佳掺杂浓度,光整流产生太赫兹过程证实了此结论的正确性。 | 古新安 朱韦臻 罗志伟 ANDREEV Y M LANSKII G V SHAIDUKO A V IZAAK T I SVETLICHNYI V A VAYTULEVICH E A ZUEV V V | 2011 | 中国光学2011,4,6: | 3 |
| 12 | Rhubarb extract partially improves mucosal integrity in chemotherapy-induced intestinal mucositis显示文摘AIM To investigate the effects of orally gavaged aqueous rhubarb extract(RE) on 5-fluorouracil(5-FU)-induced intestinal mucositis in rats. METHODS Female Dark Agouti rats(n = 8/group) were gavaged daily(1 mL) with water, high-dose RE(HDR; 200 mg/kg) or low-dose RE(LDR; 20mg/kg) for eight days. Intestinal mucositis was induced(day 5) with 5-FU(150 mg/kg) via intraperitoneal injection. Intestinal tissue samples were collected for myeloperoxidase(MPO) activity and histological examination. Xenopus oocytes expressing aquaporin 4 water channels were prepared to examine the effect of aqueous RE on cell volume, indicating a potential mechanism responsible for modulating net fluid absorption and secretion in the gastrointestinal tract. Statistical significance was assumed at P < 0.05 by one-way ANOVA. RESULTS B o d y w e i g h t w a s s i g n i f i c a n t l y r e d u c e d i n r a t s administered 5-FU compared to healthy controls(P < 0.01). Rats administered 5-FU significantly increased intestinal MPO levels(≥ 307%; P < 0.001), compared to healthy controls. However, LDR attenuated this effect in 5-FU treated rats, significantly decreasing ileal MPO activity(by 45%; P < 0.05), as compared to 5-FU controls. 5-FU significantly reduced intestinal mucosal thickness(by ≥ 29% P < 0.001) as compared to healthy controls. LDR significantly increased ileal mucosal thickness in 5-FU treated rats(19%; P < 0.05) relative to 5-FU controls. In xenopus oocytes expressing AQP4 water channels, RE selectively blocked water influx into the cell, induced by a decrease in external osmotic pressure. As water efflux was unaltered by the presence of extracellular RE, the directional flow of water across the epithelial barrier, in the presence of extracellular RE, indicated that RE may alleviate water loss across the epithelial barrier and promote intestinal health in chemotherapy-induced intestinal mucositis.CONCLUSION In summary, low dose RE improves selected parameters of mucosal integrity and reduces ileal inflammation, manifesting from 5-FU-induced intestinal mucositis. | Juliana E Bajic Georgina L Eden Lorrinne S Lampton Ker Y Cheah Kerry A Lymn Jinxin V Pei Andrea J Yool Gordon S Howarth | 2016 | World Journal of Gastroenterology2016,22,37: | 3 |
| 13 | 全颗粒饲料对奶牛生产性能的影响显示文摘饲料中的中性洗涤纤维(NDF)含量和饲料颗粒直径是影响瘤胃功能的重要因素。试验评估了以颗粒饲料为主的奶牛瘤胃健康情况、NDF消化率和生产性能。选取8头荷斯坦母牛(336±30 d,体重346±35 kg),随机分配到交叉重复试验组中,奶牛安置于牛栏,自由采食。试验期为3周,前两周是适应期,最后一周为数据收集期。各组饲粮原料相同,但物理形式不同,分为全混合日粮(TMR)和颗粒料(直径=8 mm)。两组间物理有效NDF(pe NDF)不同,TMR组为39.8%,颗粒料组为11.8%。在试验过程中,干物质采食量(DMI)、饮水量、瘤胃反刍时间、瘤胃温度和pH情况均记录。3周后收集粪样,确定潜在的可消化NDF总消化率(pdNDF)。每阶段结束后计算平均日增重和饲料转化率。颗粒料组的DMI、DMI/体重和饮水量更高。而两组间平均日增重和饲料转化率无显著差异。颗粒料组的瘤胃反刍时间为241 min·d-1低于TMR组的507 min·d-1。饲料的不同物理外形对瘤胃温度、瘤胃pH无显著影响。TMR组的pdNDF总消化率为90.25%高于颗粒料组的86.82%。试验结果表明,动物易接受完整的颗粒饲料,DMI较高,且反刍时间减少,但瘤胃pH无显著变化。TMR组的pdNDF消化率显著增加。尽管两组奶牛在DMI和纤维消化方面表现不同,但总体表现相似,两组饲料的保存时间与其物理形式有关。在短期内,提供能满足NDF需求的完全颗粒饲料可改善瘤胃健康状况和动物生产性能,而较长时间的数据则需要进一步试验。 | Wang J Yang M Cao M Lin Y Che L Q Duraipandiyan V Al-Dhabi N A Fang Z F Xu S Y Feng B Liu G Wu D Bonfante E Palmonari A Mammi L Canestrari G Fustini M Formigoni A | 2016 | 饲料博览2016,0,12: | 2 |

| 15 | Effect of intra-abdominal pressure on respiratory function in patients undergoing ventral hernia repair显示文摘AIM: To determine the influence of intra-abdominal pressure(IAP) on respiratory function after surgical repair of ventral hernia and to compare two different methods of IAP measurement during the perioperative period. METHODS: Thirty adult patients after elective repair of ventral hernia were enrolled into this prospective study.IAP monitoring was performed via both a balloontipped nasogastric probe [intragastric pressure(IGP), Ci MON, Pulsion Medical Systems, Munich, Germany] and a urinary catheter [intrabladder pressure(IBP), Uno Meter Abdo-Pressure Kit, Uno Medical, Denmark] on five consecutive stages:(1) after tracheal intubation(AI);(2) after ventral hernia repair;(3) at the end of surgery;(4) during spontaneous breathing trial through the endotracheal tube; and(5) at 1 h after tracheal extubation. The patients were in the complete supine position during all study stages.RESULTS: The IAP(measured via both techniques) increased on average by 12% during surgery compared to AI(P < 0.02) and by 43% during spontaneous breathing through the endotracheal tube(P < 0.01). In parallel, the gradient between РаСО2 and Et CO2 [Р(а-et)CO2] rose significantly, reaching a maximum during the spontaneous breathing trial. The PаO2/Fi O2 decreased by 30% one hour after tracheal extubation(P = 0.02). The dynamic compliance of respiratory system reduced intraoperatively by 15%-20%(P < 0.025). At all stages, we observed a significant correlation between IGP and IBP(r = 0.65-0.81, P < 0.01) with a mean bias varying from-0.19 mm Hg(2SD 7.25 mm Hg) to-1.06 mm Hg(2SD 8.04 mm Hg) depending on the study stage. Taking all paired measurements together(n = 133), the median IGP was 8.0(5.5-11.0) mm Hg and the median IBP was 8.8(5.8-13.1) mm Hg. The overall r2 value( n = 30) was 0.76(P < 0.0001). Bland and Altman analysis showed an overall bias for the mean values per patient of 0.6 mm Hg(2SD 4.2 mm Hg) with percentage error of 45.6%. Looking at changes in IAP between the different study stages, we found an excellent concordance coefficient of 94.9% comparing IBP and IGP( n = 117).CONCLUSION: During ventral hernia repair, the IAP rise is accompanied by changes in Р(а-et)CO2 and PаO2/Fi O2-ratio. Estimation of IAP via IGP or IBP demonstrated excellent concordance. | Konstantin M Gaidukov Elena N Raibuzhis Ayyaz Hussain Alexey Y Teterin Alexey A Smetkin Vsevolod V Kuzkov Manu LNG Malbrain Mikhail Y Kirov | 2013 | World Journal of Critical Care Medicine2013,2,2: | 2 |

| 17 | Labeling of influenza viruses with synthetic fluorescent and biotin-labeled lipids显示文摘Direct labeling of virus particles is a powerful tool for the visualization of virus–cell interaction events. However, this technique involves the chemical modification of viral proteins that affects viral biological properties. Here we describe an alternative approach of influenza virus labeling that utilizes Function-Spacer-Lipid(FSL) constructs that can be gently inserted into the virus membrane. We assessed whether labeling with fluorescent(fluo-Ad-DOPE) or biotin-labeled(biot-CMG2-DOPE) probes has any deleterious effect on influenza virus hemagglutinin(HA) receptor specificity, neuraminidase(NA) activity, or replicative ability in vitro. Our data clearly show that neither construct significantly affected influenza virus infectivity or viral affinity to sialyl receptors. Neither construct influenced the NA activities of the influenza viruses tested, except the A/Puerto Rico/8/34(H1N1) strain. Our data indicate that lipid labeling provides a powerful tool to analyze influenza virus infection in vitro. | Natalia A Ilyushina Evgeny S Chernyy Elena Y Korchagina Aleksra S Gambaryan Stephen M Henry Nicolai V Bovin | 2014 | Virologica Sinica2014,29,4: | 2 |
