1睾丸穿刺取精与正常体外排精行卵细胞胞质内单精子注射的临床结局比较显示文摘1978年,通过体外受精-胚胎移植(IVF-ET)技术成功诞生第一例试管婴儿,为女性不孕,特别是对输卵管因素造成的不孕带来了福音。然而对男性少、弱、畸形精子症引起的不孕,直到1992年卵细胞胞质内单精子注射(ICSI)获得妊娠成功,才有了突破性进展。闫文杰 杨菁 尹太郎 张博 Rumana Jafarey 徐望明 龙文 李风和 苏红 2011中华男科学杂志2011,17,3:13
2Pollutant removal from municipal wastewater employing baffled subsurface flow and integrated surface flow-floating treatment wetlands显示文摘This article reports pollutant removal performances of baffled subsurface flow, and integrated surface flow-floating treatment wetland units, when arranged in series for the treatment of municipal wastewater in Bangladesh. The wetland units(of the hybrid system) included organic, inorganic media, and were planted with nineteen types of macrophytes. The wetland train was operated under hydraulic loading fluctuation and seasonal variation. The performance analyses(across the wetland units) illustrated simultaneous denitrification and organics removal rates in the first stage vertical flow wetland, due to organic carbon leaching from the employed organic media. Higher mean organics removal rates(656.0 g COD/(m2·day)) did not completely inhibit nitrification in the first stage vertical flow system; such pattern could be linked to effective utilization of the trapped oxygen, as the flow was directed throughout the media by the baffle walls. Second stage horizontal flow wetland showed enhanced biodegradable organics removal, which depleted organic carbon availability for denitrification. The final stage integrated wetland system allowed further nitrogen removal from wastewater, via nutrient uptake by plant roots(along with nitrification), and generation of organic carbon(by the dead macrophytes) to support denitrification. The system achieved higher E. coli mortality through protozoa predation, E. coli oxidation, and destruction by UV radiation. In general, enhanced pollutant removal efficiencies as demonstrated by the structurally modified hybrid wetland system signify the necessity of such modification, when operated under adverse conditions such as: substantial input organics loading, hydraulic loading fluctuation, and seasonal variation.Tanveer Saeed Abdullah Al-Muyeed Rumana Afrin Habibur Rahman Guangzhi Sun 2014Journal of Environmental Sciences2014,26,4:7
3Clinical Analysis on Laparoscopic Salpingectomy for Ectopic Pregnancy Following IVF/ICSI-ET显示文摘Objective To investigate whether laparoscopic surgery is valuable during early pregnancy and its influence on delivery outcome of the patients.Methods A retrospective analysis was undertaken of 14 heterotopic pregnancies conceived by IVF/ICSI-ET and underwent laparoscopic salpingectomy from December 2001 to September 2009.Results The mean age of 14 patients was 29 ± 5.3 years with range of 21-39 years.The ectopic pregnancy was located in the ampulla(11 patients,78.57%) and isthmus(3 patients,21.43%).All 14 patients underwent successful laparoscopic salpingectomy without complications.Eleven(78.57%) patients delivered live singleton infants at full term via caesarean section while 3(21.43%) had spontaneous abortion.The birth weight of viable newborns ranged from 2 600 g to 3 720 g and had a high Apgar score.Conclusion During early pregnancy,the heterotopic pregnancy should be diagnosed and treated early and laparoscopic salpingectomy can be a safe and effective choice.The well experienced surgeons and accessibility of the modern equipments are mandatory.Rumana JAFAREY 2010Journal of Reproduction and Contraception2010,21,3:6
4Preparation of Chitin-PLA laminated composite for implantable application显示文摘The present study explores the possibilities of using locally available inexpensive waste prawn shell derived chitin reinforced and bioabsorbable polylactic acid(PLA)laminated composites to develop new materials with excellent mechanical and thermal properties for implantable application such as in bone or dental implant.Chitin at different concentration(1e20%of PLA)reinforced PLA films(CTP)were fabricated by solvent casting process and laminated chitin-PLA composites(LCTP)were prepared by laminating PLA film(obtained by hot press method)with CTP also by hot press method at 160C.The effect of variation of chitin concentration on the resulting laminated composite's behavior was investigated.The detailed physico-mechanical,surface morphology and thermal were assessed with different characterization technique such as FT-IR,XRD,SEM and TGA.The FTIR spectra showed the characteristic peaks for chitin and PLA in the composites.SEM images showed an excellent dispersion of chitin in the films and composites.Thermogravimetric analysis(TGA)showed that the complete degradation of chitin,PLA film,5%chitin reinforced PLA film(CTP2)and LCTP are 98%,95%,87%and 98%respectively at temperature of 500C.The tensile strength of the LCTP was found 25.09 MPa which is significantly higher than pure PLA film(18.55 MPa)and CTP2 film(8.83 MPa).After lamination of pure PLA and CTP2 film,the composite(LCTP)yielded 0.265e1.061%water absorption from 30 min to 24 h immerse in water that is much lower than PLA and CTP.The increased mechanical properties of the laminated films with the increase of chitin content indicated good dispersion of chitin into PLA and strong interfacial actions between the polymer and chitin.The improvement of mechanical properties and the results of antimicrobial and cytotoxicity of the composites also evaluated and revealed the composite would be a suitable candidate for implant application in biomedical sector.Romana Nasrin Shanta Biswas Taslim Ur Rashid Sanjida Afrin Rumana Akhter Jahan Papia Haque Mohammed Mizanur Rahman 2017Bioactive Materials2017,2,4:4
5受精第3天胚胎的融合程度与植入潜能显示文摘背景:虽然辅助生殖技术发展迅速,但是胚胎植入率仍不理想,关于胚胎融合程度与植入潜能的关系尚无定论。目的:探讨受精第3天胚胎早期融合与植入率的相关性。方法:回顾性分析420例(共移植胚胎1016个)患者在超促排卵、体外受精及胚胎移植后,植入成功胚胎早期融合情况与未植入成功胚胎早期融合情况的差别。结果及结论:受精第3天移植早期融合胚胎共200个,其中植入成功48个;受精第3天移植未早期融合胚胎共816个,其中植入成功133个,两组比较差异显著(P<0.05)。植入胚胎中有3个早期融合胚胎妊娠率达71.43%,有2个为31.91%有1个为51.06%,0个为39.81%。可见,在目前的胚胎选择标准下,胚胎早期融合可以显著提高胚胎的植入率,但是其具体机制,还有待进一步研究。张博 杨菁 尹太郎 闫文杰 Rumana Jafarey 2010中国组织工程研究与临床康复2010,14,53:3
6睾丸穿刺取精行卵胞浆内单精子注射的临床结局显示文摘目的:观察卵胞浆内单精子注射(ICSI)使用经皮睾丸穿刺取精(PTSA)、PTSA后冷冻精子及体外射出精子的临床结局。方法:对2009年2-12月接受ICSI治疗的168个周期进行回顾性分析。168个周期分为3组,体外射精组95个周期,PTSA组41个周期,PTSA后冷冻精子组32个周期。对这3组的受精、胚胎、妊娠情况进行比较。结果:PTSA组、PTSA后冷冻精子组与体外射精组比较,每个周期受精卵数、卵裂数、移植胚胎数、优质胚胎数、临床妊娠率、自然流产率、分娩率等无统计学差异。结论:对于无精症患者,PTSA结合ICSI是一种有效的治疗手段,PTSA后冷冻精子对临床结局没有影响。闫文杰 杨菁 尹太郎 张博 Rumana Jafarey 龙文 2011武汉大学学报(医学版)2011,32,1:2

18Paired δ^13Ccarb-δ^13Corg Evolution of the Dengying Formation from Northeastern Guizhou and Implications for Stratigraphic Correlation and the Late Ediacaran Carbon Cycle显示文摘This study provides δ^13C profiles from a lower-slope(Well ZK102)to basin(Bahuang Section)environment to better understand the temporal and spatial variability in δ^13Ccarb-δ^13Corg of the Yangtze Block during the Late Ediacaran.Our new δ^13C profiles together with the reported data suggest that the Upper Ediacaran successions from different depositional environments are generally bounded by negative δ^13Ccarb and/or δ^13Corg excursions in the underlying and overlying strata.Moreover,the Upper Ediacaran δ^13Ccarb profiles generally can be subdivided into two positive excursions and an interjacent negative excursion,whereas the paired δ^13Corg profiles from different depositional environments have individual variation trends.On the other hand,these data show a large surface-to-deep waterδ^13C gradient(~5‰variation in δ^13Ccarb,>10‰variation in δ^13Corg)which can be reasonably explained by the heterogeneity of the biological activities in the redox-stratified water column.Furthermore,the decoupled δ^13Ccarb-δ^13Corg pattern with large δ^13Corg perturbations at the lower slope precluded the existence of a large dissolved organic carbon reservoir at the Yangtze Block during the Late Ediacaran.Thus,the high δ^13Ccarb values in the Upper Ediacaran succession could be balanced by large amounts of buried organic carbon likely associated with high productivity.Yi Ding Daizhao Chen Xiqiang Zhou Taiyu Huang Chuan Guo Rumana Yeasmin 2020Journal of Earth Science2020,31,2:1
