1Preparation and Properties of Cellulose Nanomaterials显示文摘Cellulose is the most abundant biomass material in nature and it is mainly extracted from natural or lignocellulosic fibers.After purification,cellulose fibers exhibit two interesting features for their further transformation into nanomaterials:a hierarchical and multi-level strcture,and a semicrystalline microstructure.Different forms of cellulose nanomaterials,resulting from a top-down deconstructing strategy(cellulose nanocrystals(CNCs),cellulose nanofibrils(CNFs))or bottom-up strategy(bacterial cellulose(BC))can be prepared.Multiple mechanical shearing actions applied to cellulosic fibers release more or less the nanofibrils individually.A controlled strong acid hydrolysis treatment can be applied to cellulosic fibers allowing dissolution of non-crystalline domains.Such cellulose nanomaterials have been the focus of an exponentially increasing number of works or reviews devoted to understand such materials and their applications.They have a high potential for an emerging industry.In the nanoscale,cellulose exhibits specific properties broadening the applications of this naturally occurring polymer.An overview of existing methods for the preparation of cellulose nanomaterials and their specific properties that outperform and contrast with cellulose in the microscale is proposed.Alain Dufresne 2020Paper And Biomaterials2020,5,3:19
2Redox proteomics of tomato in response to Pseudomonas syringae infection显示文摘Unlike mammals with adaptive immunity,plants rely on their innate immunity based on pattern-triggered immunity(PTI)and effector-triggered immunity(ETI)for pathogen defense.Reactive oxygen species,known to play crucial roles in PTI and ETI,can perturb cellular redox homeostasis and lead to changes of redox-sensitive proteins through modification of cysteine sulfhydryl groups.Although redox regulation of protein functions has emerged as an important mechanism in several biological processes,little is known about redox proteins and how they function in PTI and ETI.In this study,cysTMT proteomics technology was used to identify similarities and differences of protein redox modifications in tomato resistant(PtoR)and susceptible(prf3)genotypes in response to Pseudomonas syringae pv tomato(Pst)infection.In addition,the results of the redox changes were compared and corrected with the protein level changes.A total of 90 potential redox-regulated proteins were identified with functions in carbohydrate and energy metabolism,biosynthesis of cysteine,sucrose and brassinosteroid,cell wall biogenesis,polysaccharide/starch biosynthesis,cuticle development,lipid metabolism,proteolysis,tricarboxylic acid cycle,protein targeting to vacuole,and oxidation–reduction.This inventory of previously unknown protein redox switches in tomato pathogen defense lays a foundation for future research toward understanding the biological significance of protein redox modifications in plant defense responses.Kelly Mayrink Balmant Jennifer Parker Mi-Jeong Yoo Ning Zhu Craig Dufresne Sixue Chen 2015Horticulture Research2015,2,1:7

4MicroRNAs as emerging biomarkers and therapeutic targets for pancreatic cancer显示文摘Despite tremendous efforts from scientists and clinicians worldwide, pancreatic adenocarcinoma(PDAC) remains a deadly disease due to the lack of early diagnostic tools and reliable therapeutic approaches. Consequently, a majority of patients(80%) display an advanced disease that results in a low resection rate leading to an overall median survival of less than 6 months. Accordingly, robust markers for the early diagnosis and prognosis of pancreatic cancer, or markers indicative of survival and/or metastatic disease are des-perately needed to help alleviate the dismal prognosis of this cancer. In addition, the discovery of new therapeutic targets is mandatory to design effective treatments. In this review, we will highlight the translational studies demonstrating that microRNAs may soon translate into clinical applications as long-awaited screening tools and therapeutic targets for PDAC.Marion Gayral Sébastien Jo Naima Hanoun Alix Vignolle-Vidoni Hubert Lulka Yannick Delpu Aline Meulle Marlène Dufresne Marine Humeau Maёl Chalret du Rieu Barbara Bournet Janick Sèlves Rosine Guimbaud Nicolas Carrère Louis Buscail Jérome Torrisani Pierre Cordelier 2014World Journal of Gastroenterology2014,20,32:4
5Orchestration of occludins, claudins, catenins and cadherins as players involved in maintenance of the blood-epididymal barrier in animals and humans显示文摘尽管精子在睾丸在精子发生期间被形成,阴囊的精子是不成熟的并且不能游泳或使肥沃。这些批评精子的功能在特定的钠环境被 theblood-epididymal 障碍创造的附睾被获得;附睾主细胞分泌的蛋白质把精子绑在成熟并且调整精子的 maturational 过程。在附睾, epithelialcell 房间相互作用被粘住的连接调停,为房间粘附必要,并且由紧密的连接,哪个形式 blood-epididymal 障碍。这些细胞的连接的规定被认为在在邻近的主细胞许可证之间的 epididymis.Tight 连接以内在精子成熟的过程代表一个关键决定因素在为精子成熟是必要的附睾的腔的特定的微型环境的形成。尽管我们成为了重要,在理解附睾功能和 blood-epididymal 障碍进行,用动物模型,人的附睾上有有限信息。如果我们将理解对人的附睾可归因的正常、病理学的条件工作,我们必须清楚地建立人的附睾的生理、细胞、分子的规定,描绘这些功能并且开发将使用 epididymalfunctions 到的临床的策略的 develop 工具改进不孕的处理。Daniel G.

9Review of Cellulose Nanocrystal-based Fluorophore Materials and Their Application in Metal Ion Detection显示文摘Cellulose nanocrystals(CNCs), a unique and promising natural material extracted from native cellulose, have attracted considerable attention owing to their physical properties and special surface chemistry. This review focuses on chemical conjugation strategies that can be used for preparation of fluorescent-molecule labeled CNCs and the development of biomaterials.Furthermore, their application in the detection of metal ions and future development prospects are discussed. We hope to provide a clear view of the strategies for surface fluorescent modification of CNCs and their application in detection of metal ions.Ya Wang Alain Dufresne Peter R.
