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.

2Intrahepatic natural killer T cell populations are increased in human hepatic steatosis显示文摘AIM: To determine if natural killer T cell (NKT) populations are affected in nonalcoholic fatty liver disease (NAFLD). METHODS: Patients undergoing bariatric surgery underwent liver biopsy and blood sampling during surgery. The biopsy was assessed for steatosis and immunocyte infiltration. Intrahepatic lymphocytes (IHLs) were isolated from the remainder of the liver biopsy, and peripheral blood mononuclear cells (PBMCs) were isolated from the blood. Expression of surface proteins on both IHLs and PBMCs were quantified using flow cytometry. RESULTS: Twenty-seven subjects participated in thisstudy. Subjects with moderate or severe steatosis had a higher percentage of intrahepatic CD3+/CD56+ NKT cells (38.6%) than did patients with mild steatosis (24.1%, P = 0.05) or those without steatosis (21.5%, P = 0.03). Patients with moderate to severe steatosis also had a higher percentage of NKT cells in the blood (12.3%) as compared to patients with mild steatosis (2.5% P = 0.02) and those without steatosis (5.1%, P = 0.05). CONCLUSION: NKT cells are significantly increased in the liver and blood of patients with moderate to severe steatosis and support the role of NKT cells in NAFLD.Michael Adler Sarah Taylor Kamalu Okebugwu Herman Yee Christine Fielding George Fielding Michael Poles 2011World Journal of Gastroenterology2011,17,13:10

4Abdominal obesity adversely affects bone mass in children显示文摘AIM To determine the effect of childhood obesity and insulin resistance on bone health. METHODS We conducted a cross sectional study in pubertal adolescents and young adults 13-20 years old who were either overweight/obese or normal weight. Participants were Tanner 3 or above for pubertal stage, and had fasting blood work done to measure glucose, insulin, C-reactive protein and lipid levels. Homeostatic model of insulin resistance(HOMA-IR) was calculated using the formula(Fasting Blood Glucose *Insulin/405). Body composition and bone mineral density were measured using dual energy X-ray absorptiometry(DXA; Hologic QDR 4500, Waltham, MA, United Kingdom). RESULTS Percent trunk fat was associated inversely with whole body bone mineral content(BMC), whereas HOMA-IR was associated positively with whole body BMC.CONCLUSION Our results suggest that abdominal adiposity may have an adverse effect on whole body bone parameters and that this effect is not mediated by insulin resistance.Sowmya Krishnan Michael P Anderson David A Fields Madhusmita Misra 2018World Journal of Clinical Pediatrics2018,7,1:3
5Clinical classification of symptomatic heterotopic pancreas of the stomach and duodenum:A case series and systematic literature review显示文摘BACKGROUND Heterotopic pancreas(HP)is an aberrant anatomic malformation that occurs most commonly in the upper gastrointestinal tract.While the majority of heterotopic pancreatic lesions are asymptomatic,many manifest severe clinical symptoms which require surgical or endoscopic intervention.Understanding of the clinical manifestations and symptoms of HP is limited due to the lack of large volume studies in the literature.The purpose of this study is to review symptomatic cases at a single center and compare these to a systematic review of the literature in order to characterize common clinical manifestations and treatment of this disease.AIM To classify the common clinical manifestations of heterotopic pancreas.METHODS A retrospective review was conducted of pathologic samples containing heterotopic pancreas from 2000-2018.Review was limited to HP of the upper gastrointestinal tract due to the frequency of presentation in this location.Symptomatic patients were identified from review of the medical records and clinical symptoms were tabulated.These were compared to a systematic review of the literature utilizing Pub Med and Embase searches for papers pertaining to heterotopic pancreas.Publications describing symptomatic presentation of HP were selected for review.Information including demographics,symptoms,presentation and treatment were compiled and analyzed.RESULTS Twenty-nine patient were identified with HP at a single center,with six of these identified has having clinical symptoms.Clinical manifestations included,gastrointestinal bleeding,gastric ulceration with/without perforation,pancreatitis,and gastric outlet obstruction.Systemic review of the literature yielded 232 publications detailing symptomatic cases with only 20 studies describing ten or more patients.Single and multi-patient studies were combined to form a cohort of 934 symptomatic patients.The majority of patients presented with abdominal pain(67%)combined with one of the following clinical categories:(1)Dyspepsia,(n=445,48%);(2)Pancreatitis(n=260,28%);(3)Gastrointestinal bleeding(n=80,9%);and(4)Gastric outlet obstruction(n=80,9%).The majority of cases(n=832,90%)underwent surgical or endoscopic resection with 85%reporting resolution or improvement in their symptoms.CONCLUSION Heterotopic pancreas can cause significant clinical symptoms in the upper gastrointestinal tract.Better understanding and classification of this disease may result in more accurate identification and treatment of this malformation.Michael T Le Compte Brandon Mason Keenan J Robbins Motoyo Yano Deyali Chatterjee Ryan C Fields Steven M Strasberg William G Hawkins 2022World Journal of Gastroenterology2022,28,14:3

13Innovative boron nitride-doped propellants显示文摘The U.S. military has a need for more powerful propellants with balanced/stoichiometric amounts of fuel and oxidants. However, balanced and more powerful propellants lead to accelerated gun barrel erosion and markedly shortened useful barrel life. Boron nitride(BN) is an interesting potential additive for propellants that could reduce gun wear effects in advanced propellants(US patent pending 2015-026P). Hexagonal boron nitride is a good lubricant that can provide wear resistance and lower flame temperatures for gun barrels. Further, boron can dope steel, which drastically improves its strength and wear resistance, and can block the formation of softer carbides. A scalable synthesis method for producing boron nitride nano-particles that can be readily dispersed into propellants has been developed. Even dispersion of the nano-particles in a double-base propellant has been demonstrated using a solvent-based processing approach. Stability of a composite propellant with the BN additive was verified. In this paper, results from propellant testing of boron nitride nano-composite propellants are presented, including closed bomb and wear and erosion testing. Detailed characterization of the erosion tester substrates before and after firing was obtained by electron microscopy,inductively coupled plasma and x-ray photoelectron spectroscopy. This promising boron nitride additive shows the ability to improve gun wear and erosion resistance without any destabilizing effects to the propellant. Potential applications could include less erosive propellants in propellant ammunition for large, medium and small diameter fire arms.Thelma MANNING Richard FIELD Kenneth KLINGAMAN Michael FAIR John BOLOGNINI Robin CROWNOVER Carlton P.ADAM Viral PANCHAL Eugene ROZUMOV Henry GRAU Paul MATTER Michael BEACHY Christopher HOLT Samuel SOPOK 2016Defence Technology(防务技术)2016,12,2:1
