5Endoscopic treatment for early gastric cancer显示文摘Gastric cancer remains one of the most common causes of cancer death.However the proportion of early gastric cancer(EGC)at diagnosis is increasing.Endoscopic treatment for EGC is actively performed worldwide in cases meeting specific criteria.Endoscopic mucosal resection can treat EGC with comparable results to surgery for selected cases.Endoscopic submucosal dissection(ESD)increases the en bloc and complete resection rates and reduces the local recurrence rate.ESD has been performed with expanded indication and is expected to be more widely used in the treatment of EGC through the technological advances in the near future.This review will describe the techniques,indications and outcomes of endoscopic treatment for EGC.Yang Won Min Byung-Hoon Min Jun Haeng Lee Jae J.

6Tooth regeneration: a revolution in stomatology and evolution in regenerative medicine显示文摘A tooth is a complex biological organ and consists of multiple tissues including the enamel, dentin, cementum and pulp. Tooth loss is the most common organ failure. Can a tooth be regenerated? Can adult stem cells be orchestrated to regenerate tooth structures such as the enamel, dentin, cementum and dental pulp, or even an entire tooth? If not, what are the therapeutically viable sources of stem cells for tooth regeneration? Do stem cells necessarily need to be taken out of the body, and manipulated ex vivo before they are transplanted for tooth regeneration? How can regenerated teeth be economically competitive with dental implants? Would it be possible to make regenerated teeth affordable by a large segment of the population worldwide? This review article explores existing and visionary approaches that address some of the above-mentioned questions. Tooth regeneration represents a revolution in stomatology as a shift in the paradigm from repair to regeneration: repair is by metal or artificial materials whereas regeneration is by biological restoration. Tooth regeneration is an extension of the concepts in the broad field of regenerative medicine to restore a tissue defect to its original form and function by biological substitutes.Sibel Yildirim Susan Y.

10The adult human testis transcriptional cell atlas显示文摘Human adult spermatogenesis balances spermatogonial stem cell (SSC) self-renewal and differentiation,alongside complex germ cell-niche interactions,to ensure long-term fertility and faithful genome propagation. Here,we performed single-cell RNA sequencing of -6500 testicular cells from young adults. We found five niche/somatic cell types (Leydig,myoid,Sertoli,endothelial,macrophage),and observed germline-niche interactions and key human-mouse differences. Spermatogenesis,including meiosis,was reconstructed computationally,revealing sequential coding,non-coding,and repeat-element transcriptional signatures. Interestingly,we identified five discrete transcriptional/developmental spermatogonial states,including a novel early SSC state,termed State 0. Epigenetic features and nascent transcription analyses suggested developmental plasticity within spermatogonial States. To understand the or丨gin of State 0,we profiled testicular cells from infants,and identified distinct similarities between adult State 0 and infant SSCs. Overall,our datasets describe key transcriptional and epigenetic signatures of the normal adult human testis,and provide new insights into germ cell developmental transitions and plasticity.Jingtao Guo Edward J.

12Experimental and Numerical Investigation on Impact Performance of Carbon Reinforced Aluminum Laminates显示文摘It is known that fiber metal laminates (FML) as one of hybrid materials with thin metal sheets and fiber/epoxy layers have the characteristics of the excellent damage tolerance, fatigue and impact properties with a relatively low density. Therefore, the mechanical components using FML can contribute the enhanced safety level of the sound construction toward the whole body. In this study, the impact performance of carbon reinforced aluminum laminates (CARAL) is investigated by experiments and numerical simulations. Drop weight tests are carried out with the weight of 4.7 kg at the speed of 1 and 2 m/s, respectively. Dynamic non-linear transient analyses are also accomplished using a finite element analysis software, ABAQUS. The experiment results and numerical results are compared with impact load-time histories. Also, energy-time histories are applied to investigate the impact performance of CARAL.S.H. Song Y.S.
