2MicroRNAs as a potential prognostic factor in gastric cancer显示文摘AIM:To compare the microRNA (miR) profiles in the primary tumor of patients with recurrent and non-recurrent gastric cancer.METHODS:The study group included 45 patients who underwent curative gastrectomies from 1995 to 2005 without adjuvant or neoadjuvant therapy and for whom adequate tumor content was available.Total RNA was extracted from formalin-fixed paraffin-embedded tumor samples,preserving the small RNA fraction.Initial profiling using miR microarrays was performed to identify potential biomarkers of recurrence after resection.The expression of the differential miRs was later verified by quantitative real-time polymerase chain reaction (qRT-PCR).Findings were compared between patients who had a recurrence within 36 mo of surgery (bad-prognosis group,n=14,31%) and those who did not (good-prognosis group,n=31,69%).RESULTS:Three miRs,miR-451,miR-199a-3p and miR-195 were found to be differentially expressed in tumors from patients with good prognosis vs patients with bad prognosis (P<0.0002,0.0027 and 0.0046 respectively).High expression of each miR was associated with poorer prognosis for both recurrence and survival.Using miR-451,the positive predictive value for non-recurrence was 100% (13/13).The expression of the differential miRs was verified by qRT-PCR,showing high correlation to the microarray data and similar separation into prognosis groups.CONCLUSION:This study identified three miRs,miR-451,miR-199a-3p and miR-195 to be predictive of recurrence of gastric cancer.Of these,miR-451 had the strongest prognostic impact.Baruch Brenner Moshe B Hoshen Ofer Purim Miriam Ben David Karin Ashkenazi Gideon Marshak Yulia Kundel Ronen Brenner Sara Morgenstern Marisa Halpern Nitzan Rosenfeld Ayelet Chajut Yaron Niv Michal Kushnir 2011World Journal of Gastroenterology2011,17,35:31
3云南宣威晚二叠世末生物灭绝期C1煤的地球化学特征显示文摘云南宣威雁塘煤矿晚二叠世末期C1煤层蕴含了二叠纪—三叠纪界线事件演化以及宣威肺癌高发原因方面的重要信息。本文对该矿C1煤层(包括三个分层——B1、B2和B3)进行了刻槽分层采样,采用X射线荧光光谱和电感耦合等离子体质谱测试了24个样品中常量和微量元素。利用偏光显微镜和带能谱的扫描电镜(SEMEDX)对煤中的显微组分及矿物组成进行微区分析,利用X射线衍射对低温灰化后的煤样作了矿物的半定量分析。结果表明,雁塘矿C1煤中常量元素Ca、Mn、Si含量明显高于中国煤均值;与华南二叠纪煤平均值、中国煤平均值、世界煤平均值以及地壳元素丰度相比较,雁塘矿C1煤中的W、Co、Mo、Cd、Pb、Be、Sb、Cu、Ni、Zn、Zr和V等12种微量元素相对比较富集。结合相关分析和SEM-EDX微区分析方法,对C1煤中微量元素的赋存状态进行分析发现Cs、Ga、Nb、Ba、Rb、Th、Tl、U与灰分显著正相关,表明这些元素主要以无机矿物态赋存,其它元素赋存状态复杂。结合C1煤中12种富集元素在垂向上的含量分布特征,推断Co、Cu、V、Zn应主要来源于峨眉山玄武岩风化产物;Be和Zr主要受同沉积火山灰影响;Ni则可能受峨眉山玄武岩风化及同沉积火山灰的共同影响;同沉积火山灰是C1煤中W来源之一;Sb可能受中低温热液的影响。C1煤中Zr与我国南方其他地区P/T界线粘土岩中Zr的富集规律一致。C1煤中富集的微量元素与宣威肺癌高发区可吸入颗粒物中的高含量元素一致,推断C1煤的燃烧可能与宣威肺癌高发有关。C1煤中富集的有毒有害微量元素可能与二叠纪—三叠纪之交生物大灭绝期的独特环境有密切关系。邵龙义 王娟 侯海海 张名泉 汪浩 SPIRO Baruch LARGE David 周义平 2015地质学报2015,89,1:17
4Appendicitis in children less than five years old:A challenge for the general practitioner显示文摘Acute appendicitis is one of the most common indications for abdominal surgery in pediatrics with peak incidence in the second decade of life. Acute appendicitis in the first years of life is an uncommon event. The clinical presentation is often varied and the diagnosis may be overshadowed by other medical conditions.Gastroenteritis is the most common misdiagnosis, with a history of diarrhea present in 33% to 41% of patients. Pain is the most common presenting symptom in children less than 5 years old, followed by vomiting, fever, anorexia and diarrhea. The most common physical sign is focal tenderness(61% of the patients) followed by guarding(55%), diffuse tenderness(39%), rebound(32%), and mass(6%). Neonatal appendicitis is a very rare disease with high mortality; presenting symptoms are nonspecific with abdominal distension representing the main clinical presentation. The younger the patient, the earlier perforation occurs: 70% of patients less than 3 years develop a perforation within 48 h of onset of symptoms. A timely diagnosis reduces the risk of complications. We highlight the epidemiology, pathophysiology, clinical signs and laboratory clues of appendicitis in young children and suggest an algorithm for early diagnosis.Pierluigi Marzuillo Claudio Germani Baruch S Krauss Egidio Barbi 2015World Journal of Clinical Pediatrics2015,4,2:10
5SHRIMP zircon U-Pb ages from coal beds across the Permian-Triassic boundary, eastern Yunnan, southwestern China显示文摘The first SHRIMP zircon U e Pb ages from coal beds close to the end-Permian mass extinction are reported from the C_1 coal seam in the Yantang Mine in Laibin Town, Xuanwei County, eastern Yunnan Province.Zircons were extracted from kaolinite claystone layers, defined as tonsteins(volcanic ash deposits), in the subseam B_1 and B_3 of the coal seam C_1.The U-Pb ages are 252.0 ± 2.3 Ma and 250.3 ± 2.1 Ma for the sub-seam B_1 and B_3, respectively. Within analytical uncertainties, these U-Pb ages include the time period of the onset of the mass extinction at 251.941 ± 0.037 Ma, which was obtained from the marine Meishan section in Zhejiang Province, ~1600 km away from the Yantang Mine. These new ages represent not only the first and closest ages to the PTB mass extinction in terrestrial coal beds, but also ages from the nearest site to the Emeishan volcanoes investigated so far. Therefore these new data provide the most accurate stratigraphic horizon of terrestrial facies of the end-Permian extinction in South China. The Emeishan volcanoes were likely the source of volcanic ash in the coal seams at the Xuanwei County and broader areas in South China. Furthermore, the minerals and geochemistry characteristics of the C_1 coal seam also implied the influences of contemporaneous volcanic activities.Juan Wang Long-Yi Shao Hao Wang Baruch Spiro David Large 2018Journal of Palaeogeography2018,7,2:4
6Influence of Multi-pass Friction Stir Processing on Microstructure and Mechanical Properties of Die Cast AI-7Si-3Cu Aluminum Alloy显示文摘The influence of overlap multi-pass friction stir processing on the microstructure and the mechanical properties, in particular, strength, ductility and hardness of die cast Al–7Si–3Cu aluminum alloy was investigated.It was observed that increase in the number of overlap passes friction stir processing resulted in significant refinement and redistribution of aluminum silicon eutectic phase and elimination of casting porosities. The microstructural refinement by the friction stir processing not only increases the ultimate tensile strength from 121 to273 MPa, but also increases the ductility as observed by the increase in fracture strain from 1.8% to 10%. Analysis of the fractured surface reveals that the microstructural refinement obtained by friction stir processing plays a vital role in transforming the fracture mode from completely mixed mode to the ductile mode of the fracture with increasing number of passes. The change in the size, shape, morphology and distribution of eutectic silicon particles and elimination of the porosities are the main reasons for the increases in tensile strength and ductility due to friction stir processing.L.John Baruch R.Raju V.Balasubramanian A.G.Rao I.Dinaharan 2016Acta Metallurgica Sinica(English Letters)2016,29,5:3

8Lacustrine basin evolution and coal accumulation of the Middle Jurassic in the Saishiteng coalfield, northern Qaidam Basin, China显示文摘Based on an extensive borehole survey of the Middle Jurassic coal-bearing sequences in the Saishiteng coalfield,northern Qaidam Basin(NQB),a total of 20 rock types and 5 sedimentary facies were identified,including braided river,meandering river,braided delta,meandering river delta,and lacustrine facies.The distribution of rock types and sedimentary facies contributed to the reconstruction of three periods' sedimentary facies maps of the Middle Jurassic in the Saishiteng coalfield,namely,the Dameigou age,the early Shimengou age and the late Shimengou age.That also provided the basis for the development of a three-stage depositional model of the Middle Jurassic in the NQB,indicating the lacustrine basin of the NQB in the Dameigou age and early Shimengou age were corresponding to an overfill basin,and that in the late Shimengou age was related to a balanced-fill basin.The analysis of the stability and structure of coal seams based on sedimentary facies maps showed that the preferred coal-forming facies in the Saishiteng coalfield were inter-delta bay and interdistributary bay of lower delta plain in the Dameigou age.In particular,the swamps that developed on the subaqueous palaeohigh favored the development of thick coal seams.Thus,minable coal seams may also be found along the Pingtai palaeohigh in the western part of the Saishiteng coalfield.Meng Li Long- Yi Shao Lei Liu Jing Lu Baruch Spiro Huai-Jun Wen Yong-Hong Li 2016Journal of Palaeogeography2016,5,3:2

14Using geophysical logs to identify Milankovitch cycles and to calculate net primary productivity(NPP) of the Late Permian coals,western Guizhou,China显示文摘Milankovitch periodicities of 123 kyr(eccentricity), 35.6 kyr(obliquity), and 21.2 kyr(precession) were identified in geophysical logs of three Late Permian coals: 17#, 18#, and 17 + 18#, from the Songhe mining area in western Guizhou Province. Based on the astronomic temporal framework, the periods of deposition of the 17#(5.6 m), 18#(6.4 m), and 17 + 18#(5.4 m) coals were constrained to 140.8–119.8 kyr, 160–136.2 kyr, and 135–114.9 kyr,respectively. The overall depositional period of the 18# coal of 160–136.2 kyr was further subdivided using the wavelet analysis method, into short and precise periods corresponding to the Milankovitch periodicities. It includes one eccentricity periodicity(123 kyr), three obliquity periodicities(35.6 kyr), and five precession periodicities(21.2 kyr). Different thicknesses of the subdivided coal sections, equivalent to the same time span of deposition, indicate different rates of coal deposition, i.e., thicker sections imply higher rates while the thinner sections represent lower rates. The combination of the measured average carbon concentration with the density of the coals gave rise to long-term average values of carbon accumulation rates for the Late Permian coals, in the range of 42.4–50.6 g?C?m^(-2)?a^(-1). This range corresponds to the long-term average carbon accumulation rates for the initial peat in the range of 60.6–72.3 g?C?m^(-2)?a^(-1). Based on the known quantitative relation between net primary productivity(NPP)values and long-term average carbon accumulation rates for the Holocene tropical peatlands, the range of NPP values for the Late Permian tropical peatlands was estimated as 242.4–433.8 g?C?m^(-2)?a^(-1).A comparison of existing information about peatland NPP levels of various ages and latitudes indicated that when conditions of high rain and high humidity prevail in the palaeo-peatland at given latitude, the NPP rates will vary with changes in atmospheric concentration of CO_2 and O_2. This relationship may lead to the use of coals as an indicator for the concentration of these gases(CO_2 and O_2) in the contemporaneous atmosphere encompassing the long records of coal deposition.Zhi-Ming Yan Long-Yi Shao David Large Hao Wang Baruch Spiro 2019Journal of Palaeogeography2019,8,1:2
