1A community-derived classification for extant lycophytes and ferns显示文摘发展史长通知了蕨类植物分类。当我们推断进化的树的能力改善了,针对认出生来的组的分类变得逐渐地预兆、稳定。这里,我们为 lycophytes 和蕨纲植物提供一个现代、全面分类,在下面,利用一条基于社区的途径类水平。我们 monophyly 用作主要标准让 taxa,而且目的识别保存两个广泛地被接受的存在 taxa 和界限并且与我们蕨类植物发展史的理解一致。总共,这个分类对待一在 337 个类, 51 个家庭, 14 目,和二个班估计了 11  916 种类。这个分类没在 lycophyte 和蕨纲植物上作为最后的词被打算分类,而是当前的假设的概括陈述,源于最好的可得到的数据并且在问题由熟悉植物的那些大多数塑造了。我们希望它将在蕨类植物上为最近的文学的那些想要的参考用作一个资源发展史和分类,为指导未来调查的一个框架,和推进讲话的刺激。Eric Schuettpelz Harald Schneider Alan R.

4Role of polyethylene particles in peri-prosthetic osteolysis:A review显示文摘There is convincing evidence that particles produced by the wear of joint prostheses are causal in the periprosthetic loss of bone,or osteolysis,which,if it progresses,leads to the phenomenon of aseptic loosening.It is important to fully understand the biology of this bone loss because it threatens prosthesis survival,and loosened implants can result in peri-prosthetic fracture,which is disastrous for the patient and presents a difficult surgical scenario.The focus of this review is the bioactivity of polyethylene(PE)particles,since there is evidence that these are major players in the development and progression of osteolysis around prostheses which use PE as the bearing surface.The review describes the biological consequences of interaction of PE particles with macrophages,osteoclasts and cells of the osteoblast lineage,including osteocytes.It explores the possible cellular mechanisms of action of PE and seeks to use the findings to date to propose potential nonsurgical treatments for osteolysis.In particular,a nonsurgical approach is likely to be applicable to implants containing newer,highly cross-linked PEs(HXLPEs),for which osteolysis seems to occur with much reduced PE wear compared with conventional PEs.The caveat here is that we know little as yet about the bioactivity of HXLPE particles and addressing this constitutes our next challenge.Gerald J Atkins David R Haynes Donald W Howie David M Findlay 2011World Journal of Orthopedics2011,2,10:11
5Management of adults with coarctation of aorta显示文摘Coarctation of the aorta(CoA)is a relatively common congenital cardiac defect often causing few symptoms and therefore can be challenging to diagnose.The hallmark finding on physical examination is upper extremity hypertension,and for this reason,CoA should be considered in any young hypertensive patient,justifying measurement of lower extremity blood pressure at least once in these individuals.The presence of a significant pressure gradient between the arms and legs is highly suggestive of the diagnosis.Early diagnosis and treatment are important as long-term data consistently demonstrate that patients with CoA have a reduced life expectancy and increased risk of cardiovascular complications.Surgical repair has traditionally been the mainstay of therapy for correction,although advances in endovascular technology with covered stents or stent grafts permit nonsurgical approaches for the management of older children and adults with native CoA and complications.Persistent hypertension and vascular dysfunction can lead to an increased risk of coronary disease,which,remains the greatest cause of long-term mortality.Thus,blood pressure control and periodic reassessment with transthoracic echocardiography and threedimensional imaging(computed tomography or cardiac magnetic resonance)for should be performed regularly as cardiovascular complications may occur decades after the intervention.Pradyumna Agasthi Sai Harika Pujari Andrew Tseng Joseph N Graziano Francois Marcotte David Majdalany Farouk Mookadam Donald J Hagler Reza Arsanjani 2020World Journal of Cardiology2020,12,5:8

7双月安环己烷草酸铂对肝癌细胞DNA损伤修复基因表达影响及其机制显示文摘目的初步明确肝癌细胞中特异性表达缺失的DNA损伤修复基因(GADD45β)近端启动子序列,并探索双月安环己烷草酸铂(Oxaliplatin)对人肝癌细胞HepG2中GADD45β基因表达影响及可能机制.方法以30~50个碱基间隔体外人工合成GADD45β近端启动子序列(-547至-436),分别插入pGL3 basic荧光素表达质粒的荧光素基因上游,以电穿孔法转染HepG2,根据启动子活性强度结合TRANSFAC数据库分析可能存在的转录调节因子结合位点;以Northern印迹和实时荧光定量PCR比较Oxaliplatin作用前后HepG2细胞GADD45β表达,并在此基础上进一步比较Oxaliplatin对GADD45β启动子活性的诱导作用.结果GADD45β近端启动子中含有E2F-1(-470/-436)和核因子(NF)-KB(-547/-520)转录调节因子与启动子结合位点,并可能存在'抑制区'.Oxaliplatin能明显诱导HepG2中GADD45β表达,并呈剂量-效应正相关关系,同时Oxaliplatin能相应诱导E2F-1启动子活性.结论Oxaliplatin能明显诱导肝癌细胞中特异性缺失的GADD45β基因表达,增强转录调节因子E2F-1的表达水平是其可能的作用机制.邱伟华 ZHOU Bing-sen Donald David 陈皓 杨卫平 李宏为 YEN Yun 2005中华消化杂志2005,25,9:5
8AIDS-associated plasmablastic lymphoma presenting as a poorly differentiated esophageal tumor: A diagnostic dilemma显示文摘Plasmablastic lymphoma (PBL) is a rare form of diffuse large B-cell lymphoma characterized by weak/absent expression of conventional B-cell markers and strong expression of plasma cell markers. It is strongly associated with human immunodeficiency virus (HIV) and Epstein Barr virus infection, and shows an unusual tropism to the oral cavity. Herein we describe a patient with AIDS who presented with weight loss and dysphagia owing to a large gastroesophageal mass. His radiographic and endoscopic findings and long history of cigarette consumption suggested carcinoma. Biopsy demonstrated a poorly differentiated tumor stained negatively to routine lymphoid markers including CD20. However, gene rearrangement studies confirmed a B-cell process and a more detailed immunohistochemical analysis revealed the cells stained positively for CD138 (plasma cell antigen). These findings were diagnostic of PBL. Our report reviews the wide differential diagnosis of PBL and underscores the importance of a broad array of viral and molecular studies needed to establish this diagnosis.Deepthi Mani Donald G Guinee Jr David M Aboulafia 2008World Journal of Gastroenterology2008,14,27:4
9消融的冰川:加拿大班夫国家公园亚高山带鲍湖中持久性有机氯的主要来源显示文摘有机氯杀虫剂和多氯联苯(PCB)是环境中普遍而稳固的化合物。现已查明,由于它们从温暖的地区逐渐蒸发出来,并在较冷的地区凝聚下来,因而它们富集在寒冷的环境中。在本研究中,我们的结果是,消融的冰川供给阿尔伯达亚高山带湖泊中的有机氯输入量为50%~97%,而提供的水量为73%。对氚的分析结果表明,在夏季的中、晚期,至少10%的冰川消融物是在1950~1970年期间沉积下来的,这期间它受到有机氯更多的污染。这一发现表明,气候变暖可能会使消融的冰川成为日益增多的淡水污染物来源。由于有机物贫乏的冰川粘土对多氯联苯这样的疏水化合物的吸附能力有限,因此冰川水流带来的有机氯大多呈溶解状态。Jules M.

16Hepatocellular carcinoma after Iocoregional therapy:Magnetic resonance imaging findings in falsely negative exams显示文摘AIM:To elucidate causes for false negative magnetic resonance imaging(MRI)exams by identifying imaging characteristics that predict viable hepatocellular carcinoma(HCC)in lesions previously treated with locoregional therapy when obvious findings of recurrence are absent.METHODS:This retrospective institutional review board-approved and Health Insurance Portability and Accountability Act-compliant study included patients who underwent liver transplantation at our center between 1/1/2000 and 12/31/2012 after being treated for HCC with locoregional therapy.All selected patients had a contrast-enhanced MRI after locoregional therapy within 90 d of transplant that was prospectively interpreted as without evidence of residual or recurrenttumor.Retrospectively,2 radiologists,blinded to clinica and pathological data,independently reviewed the pre transplant MRIs for 7 imaging features.Liver explan histopathology provided the reference standard,with clinically significant tumor defined as viable tumor≥1.0cm in maximum dimension.Fisher’s exact test was firs performed to identify significant imaging features.RESULTS:Inclusion criteria selected for 42 patients with 65 treated lesions.Fourteen of 42 patients(33%and 16 of 65 treated lesions(25%)had clinically significant viable tumor on explant histology.None o the 7 imaging findings examined could reliably and reproducibly determine which treated lesion had viable tumor when the exam had been prospectively read as without evidence of viable HCC.CONCLUSION:After locoregional therapy some treated lesions that do not demonstrate any MRI evidence o HCC will contain viable tumor.As such even patients with a negative MRI following treatment should receive regular short-term imaging surveillance because some have occult viable tumor.The possibility of occult tumo should be a consideration when contemplating any action which might delay liver transplant.David Becker-Weidman Jesse M Civan Sandeep P Deshmukh Christopher G Roth Steven K Herrine Laurence Parker Donald G Mitchell 2016World Journal of Hepatology2016,8,16:2
