1UPLAND EROSION MODELING WITH CASC2D-SED显示文摘Developed at Colorado State University, CASC2D-SED is a physically-based model simulating the hydrologic response of a watershed to a distributed rainfall field. The time-dependent processes include: precipitation, interception, infiltration, surface runoff and channel routing, upland erosion, transport and sedimentation. CASC2D-SED is applied to Goodwin Creek, Mississippi. The watershed covers 21 km2 and has been extensively monitored both at the outlet and at several internal locations by the ARS-NSL at Oxford, MS. The model has been calibrated and validated using rainfall data from 16 meteorological stations, 6 stream gauging stations and 6 sediment gauging stations. Sediment erosion/deposition rates by size fraction are predicted both in space and time. Geovisualization, a powerful data exploration technique based on GIS technology, is used to analyze and display the dynamic output time series generated by the CASC2D-SED model.Pierre JULIEN Rosalía ROJAS 2002International Journal of Sediment Research2002,17,4:7
2Retrograde-viewing device improves adenoma detection rate in colonoscopies for surveillance and diagnostic workup显示文摘AIM:To determine which patients might benefit most from retrograde viewing during colonoscopy through subset analysis of randomized,controlled trial data.METHODS:The Third Eye Retroscope Randomized Clinical Evaluation(TERRACE) was a randomized,controlled,multicenter trial designed to evaluate the efficacy of a retrograde-viewing auxiliary imaging device that is used during colonoscopy to provide a second video image which allows viewing of areas on the proximal aspect of haustral folds and flexures that are difficult to see with the colonoscope's forward view.We performed a post-hoc analysis of the TERRACE data to determine whether certain subsets of the patient population would gain more benefit than others from use of the device.Subjects were patients scheduled for colonoscopy for screening,surveillance or diagnostic workup,and each underwent same-day tandem examinations with standard colonoscopy(SC) and Third Eye colonoscopy(TEC),randomized to SC followed by TEC or vice versa.RESULTS:Indication for colonoscopy was screening in 176/345 subjects(51.0%),surveillance after previous polypectomy in 87(25.2%) and diagnostic workup in 82(23.8%).In 4 subjects no indication was specified.Previously reported overall results had shown a net additional adenoma detection rate(ADR) with TEC of 23.2% compared to SC.Relative risk(RR) of missing adenomas with SC vs TEC as the initial procedure was 1.92(P = 0.029).Post-hoc subset analysis shows additional ADRs for TEC compared to SC were 4.4% for screening,35.7% for surveillance,55.4% for diagnostic and 40.7% for surveillance and diagnostic combined.The RR of missing adenomas with SC vs TEC was 1.11(P = 0.815) for screening,3.15(P = 0.014) for surveillance,8.64(P = 0.039) for diagnostic and 3.34(P = 0.003) for surveillance and diagnostic combined.Although a multivariate Poisson regression suggested gender as a possibly significant factor,subset analysis showed that the difference between genders was not statistically significant.Age,bowel prep quality and withdrawal time did not significantly affect the RR of missing adenomas with SC vs TEC.Mean sizes of adenomas detected with TEC and SC were similar at 0.59 cm and 0.56 cm,respectively(P = NS).CONCLUSION:TEC allows detection of significantly more adenomas compared to SC in patients undergoing surveillance or diagnostic workup,but not in screening patients(ClinicalTrials.gov Identifier:NCT01044732).Peter D Siersema Amit Rastogi Anke M Leufkens Paul A Akerman Kassem Azzouzi Richard I Rothstein Frank P Vleggaar Alessandro Repici Giacomo Rando Patrick I Okolo Olivier Dewit Ana Ignjatovic Elizabeth Odstrcil James East Pierre H Deprez Brian P Saunders Anthony N Kalloo Bradley Creel Vikas Singh Anne Marie Lennon Daniel C DeMarco 2012World Journal of Gastroenterology2012,18,26:6
3TAT-Gap19通过抑制啮齿动物星形胶质细胞的连接蛋白43半通道发挥抗惊厥作用显示文摘越来越多的证据表明,星形胶质细胞连接蛋白43(Cx43)信号在癫痫中发挥至关重要的作用。但是,由于通过实验方法鉴别Cx43间隙连接通道(GJCs)和半通道(HCs)的技术尚不成熟,导致目前尚无法确定哪个通道在癫痫的发生中发挥更重要的作用。因此,本研究观察TAT-Gap19(Cx模拟肽)是否通过抑制Cx43半通道而非Cx43间隙连接通道影响实验诱导的啮齿动物癫痫发作。急性海马切片小鼠染料摄取实验表明,星形胶质Cx43半通道响应化学惊厥毛果芸香碱的作用而开放,并且可被TAT-Gap19抑制。体内实验中,毛果芸香碱诱导的癫痫发作及相伴随的D-丝氨酸微透析液的增长水平被Cx43半通道的抑制所抑制。此外,TAT-Gap19的抗惊厥作用被外源性D-丝氨酸给药逆转,这表明,抑制Cx43半通道可以通过降低细胞外D-丝氨酸水平来防止癫痫发作。抑制Cx43半通道的抗惊厥特性在电癫痫小鼠模型(如急性6 Hz难治性癫痫发作模型和慢性6 Hz角膜点燃模型)中得到了进一步的证实。总而言之,这些结果表明,Cx43半通道在癫痫发作中可以起到一定作用,并且有成为癫痫治疗中新型用药靶点的潜力。Walrave L Pierre A Albertini G Aourz N De Bundel D Van Eeckhaut A Vinken M Giaume C Leybaert L Smolders I 聂昊 2018神经损伤与功能重建2018,13,6:5

5CD5 expression promotes IL-10 production through activation of the MAPK/Erk pathway and upregulation of TRPC1 channels in B lymphocytes显示文摘CD5 is constitutively expressed on T cells and a subset of mature normal and leukemic B cells in patients with chronic lymphocytic leukemia(CLL).Important functional properties are associated with CD5 expression in B cells,including signal transducer and activator of transcription 3 activation,IL-10 production and the promotion of B-lymphocyte survival and transformation.However,the pathway(s)by which CD5 influences the biology of B cells and its dependence on B-cell receptor(BCR)co-signaling remain unknown.In this study,we show that CD5 expression activates a number of important signaling pathways,including Erk1/2,leading to IL-10 production through a novel pathway independent of BCR engagement.This pathway is dependent on extracellular calcium(Ca2+)entry facilitated by upregulation of the transient receptor potential channel 1(TRPC1)protein.We also show that Erk1/2 activation in a subgroup of CLL patients is associated with TRPC1 overexpression.In this subgroup of CLL patients,small inhibitory RNA(siRNA)for CD5 reduces TRPC1 expression.Furthermore,siRNAs for CD5 or for TRPC1 inhibit IL-10 production.These findings provide new insights into the role of CD5 in B-cell biology in health and disease and could pave the way for new treatment strategies for patients with B-CLL.Soizic Garaud Taher E Taher Marjolaine Debant Miguel Burgos Sarra Melayah Christian Berthou Kaushal Parikh Jacques-Olivier Pers Damien Luque-Paz Gilles Chiocchia Maikel Peppelenbosch David A Isenberg Pierre Youinou Olivier Mignen Yves Renaudineau Rizgar A Mageed 2018Cellular & Molecular Immunology2018,15,2:2
