| 1 | Nonalcoholic Fatty Liver Disease after Liver Transplant显示文摘Nonalcoholic fatty liver disease(NAFLD)is one of the most common causes of chronic liver disease in the world.The rising prevalence of nonalcoholic steatohepatitis(NASH)has led to a 170%increase in NASH cirrhosis as the listing indication for liver transplantation from 2004 to 2013.As of 2018,NASH has overtaken hepatitis C as an indication for liver transplantation in the USA.After liver transplantation,the allograft often develops recurrent NAFLD among patients with known NASH cirrhosis.In addition to recurrent disease,de novo NAFLD has been reported in patients with other indications for liver transplantation.In this review,we will discuss the risk factors associated with recurrent and de novo NAFLD,natural course of the disease,and management strategies after liver transplantation. | Akshay Shetty Fanny Giron Mukul K.Divatia Muhammad I.Ahmad Sudha Kodali David Victor | 2021 | Journal of Clinical and Translational Hepatology2021，9，3： | 1 |
| 2 | Effects of Ni doping on the structural properties and collapse of magnetic ordering in NdFe_(1-x)Ni_xO_3(0.1 ≤x≤ 0.7) orthoferrites显示文摘Nd Fe_(1-x)Ni_xO_3(0.1 ≤ x ≤ 0.7) orthoferrites are synthesized by solid state reaction method, and the structural properties of these materials are investigated by employing x-ray diffraction(XRD), scanning electron microscopy(SEM) and M o¨ssbauer spectroscopy. The orthorhombic structure is observed in all systems; however, with the increase in Ni doping,the increase in tolerance factor and the decrease in the cell volume are observed. Orthorhombic distortion decreases with Ni content increasing up to 50%, while above 50% Ni doping it increases. SEM examination indicates the increases in grain size and intermixing of grains with increase in Ni concentration. Comparison between bulk and theoretical densities shows that in each of all samples porosity is less than 2%. M?ssbauer spectroscopic investigations are performed to explain local structure, Fe oxidation states and collapse of the magnetic ordering. In these samples the Fe oxidation state remains+3 and there is no considerable increase in hole states observed; however due to mismatch of the ionic radii between Fe^(3+) and Ni^(3+), octahedral distortions, sagging and distribution of hyperfine parameters increase with increase in Ni concentration. The major factors behind the collapse of magnetic ordering in the Ni-doped systems are the weakening of the super-exchange interactions, decrease in the Neel temperature, increase in spin–spin relaxation frequency and high spin to low spin transition. | I.Ahmad M.J.Akhtar M.Siddique | 2016 | Chinese Physics B2016，25，2： | 0 |
| 3 | Diffusion of Six-Atom Cu Islands on Cu(111)and Ag(111)显示文摘Diffusion of Cu hexamer islands on Cu(111)and Ag(111)is studied using a molecular dynamics simulation technique with many-body potentials obtained from the embedded atom method.Simulations are carried out at temperatures 300,500 and 700 K,showing that shape-changing multiple-atom processes are more helpful for the diffusion rather than concerted motion of islands.Arrhenius plots of the diffusion coefficients provide effective energy barrier values of 161.29±5 meV for Cu(111)and 179.34±5 meV for Ag(111)surfaces.At 700K,one pop-up atom among island atoms is observed with correlative changes in the position and shape of the lower-layer adatoms. | Sardar Sikandar Hayat I.Ahmad M.Arshad Choudhry | 2011 | Chinese Physics Letters2011，28，5： | 0 |
| 4 | 离子束辐照的碳纳米管及其物性研究显示文摘离子束辐照通常被认为导致材料产生缺陷,形成无序结构,从而破坏材料的性能。但是,最近利用离子束辐照碳纳米管的实验显示离子束辐照碳纳米管形成无定形的过程不能用传统的离子束辐照材料的机制来解释,离子束辐照可导致碳纳米管形成一些自组装结构,如无定形碳纳米结和碳纳米管连接结等。研究还发现离子束辐照的碳纳米管薄膜在导电性和场发射性能方面都能得到明显的增强。 | 闫隆 倪志春 I.Ahmad 周广颖 王雯君 巩金龙 周兴泰 朱德彰 | 2010 | 原子核物理评论2010，27，3： | 0 |

| 7 | Trace-Rare-Gas Optical Emission Spectroscopy of Nitrogen Plasma Generated at a Frequency of 13.56 MHz显示文摘Optical emission spectroscopic measurement of trace rare gas is carried out to determinethe density of nitrogen (N) atom, in a nitrogen plasma, as a function of filling pressureand RF power applied. 2% of argon, used as an actinometer, is mixed with nitrogen. In orderto normalize the changes in the excitation cross section and electron energy distribution functionat different operational conditions, the Ar-Ⅰ emission line at 419.83 nm is used, which is of nearlythe same excitation efficiency coefficient as that of the nitrogen emission line at 493.51 nm. It isobserved that the emission intensity of the selected argon and atomic nitrogen lines increases withboth pressure and RF power, as does the nitrogen atomic density. | N.U.REHMAN F.U.KHAN S.NASEER G.MURTAZA S.S.HUSSAIN I.AHMAD M.ZAKAULLAH | 2011 | Plasma Science and Technology2011，13，2： | 0 |
