1Endoscopic treatment of chronic pancreatitis显示文摘慢性胰炎的治疗很长时间是只外科的。最近,内视镜的治疗广泛地变得用作一种主要治疗学的选择。开始为胰腺囊肿和假包囊的排水表现了,内视镜的治疗被使适应胆汁、胰腺的管狭窄。允许存取到胰腺的管的胰腺的括约肌切开术第一被报导。第二,小型机关枪的一种的内视镜的方法叮当响,胆汁管的膨胀,和石头抽取被用于胰腺的管。不过,新改进是必要的:胰腺的石头抽取的失败认为身体外的冲击波碎石术的发展正当;胰腺的狭窄的膨胀被牧草与一台新设备改进;而且 endosonography 为腹的块, gastro-cystostomy, duodeno-cystostomy 和 pancreatico-gastrostomy 允许指导。尽管内视镜的治疗越来越经常被接受,指示仍然被辩论。Laurent Heyries Jose Sahel 2007World Journal of Gastroenterology2007,13,46:6
2An in vitro evaluation of novel NHA/zircon plasma coating on 316L stainless steel dental implant显示文摘The surface characteristics of an implant that influence the speed and strength of osseointegration include crystal structure and bioactivity. The aim of this study was to evaluate the bioactivity of a novel natural hydroxyapatite/zircon(NHA/zircon) nanobiocomposite coating on 316L stainless steel(SS) dental implants soaking in simulated body fluid. A novel NHA/zircon nanobiocomposite was fabricated with 0(control),5, 10, and 15 wt% of zircon in NHA using ball mill for 1 h. The composite mixture was coated on SS implants using a plasma spray method.Scanning electron microscopy(SEM) was used to evaluate surface morphology, and X-ray diffraction(XRD) was used to analyze phase composition and crystallinity(Xc). Further, calcium ion release was measured to evaluate the coated nanobiocomposite samples. The prepared NHA/zircon coating had a nanoscale morphological structure with a mean crystallite size of 30–40 nm in diameter and a bone-like composition,which is similar to that of the biological apatite of a bone. For the prepared NHA powder, high bioactivity was observed owing to the formation of apatite crystals on its surface. Both minimum crystallinity(Xc=41.1%) and maximum bioactivity occurred in the sample containing 10 wt% of zircon because of minimum Xcand maximum biodegradation of the coating sample.Ebrahim Karamian Mahmood Reza Kalantar Motamedi Amirsalar Khandan Parisa Soltani Sahel Maghsoudi 2014Progress in Natural Science:Materials International2014,24,2:6
3A generalized supervised classification scheme to produce provincial wetland inventory maps:an application of Google Earth Engine for big geo data processing显示文摘Wetlands are important natural resources due to their numerous ecological services.Consequently,identifying their locations and extents is imperative.The stability,repeatability,cost-effectiveness,multi-scale coverage,and proper spatial resolution imagery of satellites provide a valuable opportunity for their use in various large-scale applications,such as provincial wetland mapping.To do so,it is required to(1)process and classify big geo data(i.e.a large amount of satellite datasets)in a time-and computationally-efficient approach and(2)collect a large amount of field samples.In this study,Google Earth Engine(GEE)and machine learning algorithms were utilized to process thousands of remote sensing images and produce provincial wetland inventory maps of the three Canadian provinces of Manitoba,Quebec,and Newfoundland and Labrador(NL).Additionally,using GEE,a generalized supervised classification method is proposed to produce a regional wetland map from a large area(e.g.,a province)when lacking field samples.In fact,using the field data from only Manitoba and assuming that all wetlands in Canada have similar characteristics,the wetland maps were generated for the other two provinces.The overall classification accuracies for Manitoba,Quebec,and NL were 84%,78%,and 82%,respectively,indicating the high potential of the proposed method for aiding provincial wetland inventory systems.Meisam Amani Brian Brisco Majid Afshar S.Mohammad Mirmazloumi Sahel Mahdavi Sayyed Mohammad Javad Mirzadeh Weimin Huang Jean Granger 2019Big Earth Data2019,3,4:4
4Dynamic full-field optical coherence tomography:3D live-imaging of retinal organoids显示文摘Optical coherence tomography offers astounding opportunities to image the complex structure of living tissue but lacks functional information.We present dynamic full-field optical coherence tomography as a technique to noninvasively image living human induced pluripotent stem cell-derived retinal organoids.Coloured images with an endogenous contrast linked to organelle motility are generated,with submicrometre spatial resolution and millisecond temporal resolution,creating a way to identify specific cell types in living tissue via their function.Jules Scholler Kassandra Groux Olivier Goureau Jose-Alain Sahel Mathias Fink Sacha Reichman Claude Boccara Kate Grieve 2020Light(Science & Applications)2020,9,1:2
