| 1 | Characterization of hepatic progenitors from human fetal liver using CD34 as a hepatic progenitor marker显示文摘AIM: To enrich putative hepatic progenitors from the developing human fetal liver using CD34 as a marker. METHODS: Aborted fetuses of 13-20 wk were used for the isolation of liver cells. The cells were labeled with anti CD34; a marker used for isolating progenitor population and the cells were sorted using magnetic cell sorting. The positive fractions of cells were assessed for specific hepatic markers. Further, these cells were cultured in vitro for long term investigation. RESULTS: Flow cytometric and immunocytochemical analysis for alphafetoprotein (AFP) showed that the majority of the enriched CD34 positive cells were positive for AFP. Furthermore, these enriched cells proliferated in the long term and maintained hepatic characteristics in in vitro culture. CONCLUSION: The study shows that aborted human fetal liver is a potential source for isolation of hepatic progenitors for clinical applications. The study also demonstrates that CD34 can be a good marker for the enrichment of progenitor populations. | Parveen Nyamath Ayesha Alvi Aejaz Habeeb Sanjeev Khosla Aleem A Khan CM Habibullah | 2007 | World Journal of Gastroenterology2007，13，16： | 9 |
| 2 | Corrosion behavior of cold-rolled and post heat-treated 316L stainless steel in 0.9wt%NaCl solution显示文摘The effect of cold rolling and post-rolling heat treatment on the microstructural and electrochemical properties of the 316L stainless steel was investigated.Two-pass and four-pass cold-rolled stainless steel specimens were heat-treated by annealing at 900℃followed by quenching in water.During the cold rolling,the microstructure of the as-received specimen transformed from austenite to strain-inducedα′-martensite due to significant plastic deformation that also resulted in significant grain elongation(i.e.,~33%and 223%increases in the grain elongation after two and four rolling passes,respectively).The hardness of the heat-treated as-received specimen decreased from HV 190 to 146 due to the recovery and recrystallization of the austenite grain structure.The cyclic polarization scans of the as-rolled and heat-treated specimens were obtained in 0.9wt%NaCl solution.The pitting potential of the four-pass rolled specimen was significantly increased from 322.3 to 930.5 mV after post-rolling heat treatment.The beneficial effect of the heat treatment process was evident from~10-times-lower corrosion current density and two-orders-of-magnitude-lower passive current density of the heat-treated specimens compared with those of the as-rolled specimens.Similarly,appreciably lower corrosion rate(3.302×10^(−4)mm/a)and higher pitting resistance(1115.5 mV)were exhibited by the postrolled heat-treated specimens compared with the as-rolled 316L stainless steel specimens. | K.Bin Tayyab A.Farooq A.Ahmed Alvi A.Basit Nadeem K.M.Deen | 2021 | International Journal of Minerals,Metallurgy and Materials2021，28，3： | 4 |
| 3 | 中阿40m射电望远镜选址与电磁环境监测显示文摘优良站址的选择是射电望远镜完成既定科学目标并实现高效运行的重要保障。影响射电望远镜选址的主要因素包括电磁环境、水文、气象、地质条件、隔离性与可及性等。对于射电天文观测而言,来自宇宙天体的射电信号往往极其微弱,对望远镜系统及设备的灵敏度要求极高。然而,随着人类活动的不断加强,人们日常工作和生活中使用的电子通讯设备越来越多,无线电干扰源呈爆炸式涌现。在射电望远镜选址工作中,进行电磁环境监测,选择一个电磁环境良好的站址,对于射电望远镜实现常规观测运行、获取有效数据资料至关重要。同时,电磁环境监测结果也是射电望远镜接收机系统研制、站址电磁环境及无线电宁静区立法保护的重要依据。中阿天文学者和技术人员历时1年半完成了16个候选站址的初步勘察,并对优选出的3个主要候选站址进行了深入细致的电磁环境监测工作,获得了大量可靠数据。中阿双方依据电磁环境监测结果并结合各主要候选站址的水文、气象、地质及道路等条件,最终将位于Talacasto戈壁的3号候选站址确定为中阿CART射电望远镜的建设站点。 | 赵卫普 李建斌 李金增 孙建民 齐力 罗滔 马晓耘 莫铠玮 李鹏程 夏跃兵 MALLAMACI C C PODESTA R C PACHECO A M ACTIS E CASTRO J I ALVIS R H LOPEZ C E FRANCILE C PODESTA F PEREZ J | 2014 | 天文学进展2014，32，3： | 4 |
| 4 | 层状双氢氧化物(LDHs)的合成及应用(英文)显示文摘Layered double hydroxides, a class of anionic clays possessing sandwich like structure in which negative anions are sandwiched into positively charged metal layers in a repeating manner, have been studied extensively. Layered double hydroxides could be fabricated with combination of different divalent(Cd^(2+), Mn^(2+), Fe^(2+), Pb^(2+)) and trivalent(Al^(3+), Cr^(3+), Fe^(3+)) metals and layered arrangement imparts unique properties such as adsorption properties and catalytic properties in these compounds. Exciting feature of these compounds is the memory effect. There are a number of methods to synthesize these layered compounds, such as co-precipitation, hydrothermal, sol-gel, urea hydrolysis,?etc. The synthesized LDHs can be characterized morphologically and compositionally i.e. scanning electron microscopy, transmission electron microscopy, powder X-Ray diffraction, Mossbauer spectroscopy, thermogravimetric analysis, XPS, etc. The wonderful feature of layered double hydroxides is the pliancy of interlayer space enabling them to accommodate various anionic species, and high surface area making them efficient in numerous applications such as adsorbents, anion exchange, catalysts, and biological compatible. | Saba Jamil Afaaf Rahat Alvi Shanza Rauf Khan Muhammad Ramzan Saeed Ashraf Janjua | 2019 | 化学进展2019，31，2： | 3 |
| 5 | An investigation of the effects of synthesized zinc oxide nanoparticles on the properties of water-based drilling fluid显示文摘The deterioration of drilling fluid properties during deep drilling causes problems like inefficient cutting removal,fluid invasion,and shale swelling,which increases non-productive time(NPT)and cost.Recently nanoparticles(NPs)based drilling fluid are introduced to address these impediments since these particles prove their advantages in different stages of petroleum exploration and recovery.Previous developments are concerned with the use of commercial zinc oxide(ZnO)NPs in inorganic KCl salt-based drilling fluid,although application of KCl in drilling fluid arouses environmental complications.In this study,ZnO NPs prepared in the laboratory are used in water-based drilling fluid(WBDF)to assess the effect of nanoparticles on the properties of drilling fluid at two temperature conditions of 40C and 80C.A base mud is formulated,and ZnO NPs with five different concentrations of 0.05,0.1,0.5,1.0,and 2.0 wt%are mixed with the base mud.The experimental analysis shows that NPs improve the rheological properties of WBDF.When the concentration of NPs was 0.1 wt%,the yield point increased by 61.54%at 40C,and when the concentration of NPs was 0.05 wt%,the yield point increased by 60%at 80C.Besides,when the concentration of NPs is 0.05 wt%,10-sec gel strengths are enhanced by 25%and 50%at 40C and 80C,respectively.The API low-pressure low-temperature(LPLT)filter volume is not significantly affected by the addition of NPs in WBDF.However,mud cake thickness continuously reduces with the increase of NPs concentrations.This result reveals that a superior rheological improvement is achieved at low NPs concentration(0.05 wt%)at higher temperature. | Muhammad Hasibul Ahasan MdFazla Alahi Alvi Nayem Ahmed Md.Saiful Alam | 2022 | Petroleum Research2022，7，1： | 2 |
