Neural Regeneration Research 2010年第2期5卷 98-101页

作者： Jiangtao Liu Kuncheng Li jinglin zhang Xiaoli Wu Biao Chen Department of Radiology Xuanwu Hospital Capital Medical University Beijing 100053 China Key Laboratory of Ministry of Education on Neurodegenerative Diseases Xuanwu Hospital Capital Medical University Beijing 100053 China

BACKGROUND： Imaging has been used to determine gray matter volume and metabolism in subjects with depressed Parkinson＇s disease （DPD）. OBJECTIVE： To reveal abnormalities in orbitofrontal white matter and the anterior cingulate bundle in depressed and non-depressed Parkinson＇s disease （NDPD） patients using diffusion tensor imaging. DESIGN, TIME AND SETTING： A non-randomized, concurrent, control, neuroimaging study was performed at the Laboratory of Neurodegenerative Diseases and Center of Neuroimage, Xuanwu Hospital of Capital Medical University from July 2008 to January 2009. PARTICIPANTS： A total of 30 Parkinson＇s disease patients, including 14 males and 16 females, were included in the present study. All patients met Brain Bank criteria for idiopathic Parkinson＇s disease formulated by the United Kingdom Parkinson＇s Disease Society. Patients, who underwent previous head surgery, exhibited abnormal density on T2-weighted images, or Mini-Mental State Examination scores 〈 corresponding education level, were excluded from the study. METHODS： All 35 patients underwent MRI scans, including traditional T2-weighted and DTI scans. The patients were assigned to DPD （n = 16） and NDPD （n = 14） groups according to the Diagnostic and Statistical Manual of Mental Disorders-IV （DSM-IV） criteria. The fractional anisotropy values of regions of interest were compared between the NDPD and DPD groups. MAIN OUTCOME MEASURES： Abnormalities in the orbitofrontal white matter and anterior cingulate bundle. RESULTS： Compared with the NDPD group, the DPD group exhibited significantly lower fractional anisotropy values in orbitofrontal white matter and anterior cingulate bundle （P 〈 0.05）. CONCLUSION： Microstructure abnormalities existed in the orbitofrontal and anterior cingulate regions in DPD patients. This is the first report of abnormalities in the orbitofrontal white matter region in DPD patients.

Gas atomized 4J36 alloy powder was milled for 72 h then mixed with ZrW2O8 powder and sintered at 600℃ for 4 h under argon atmosphere. 4J36/ZrW2O8 composites containing 10 vol.%, 20 vol.%, 30 vol.%, and 40 vol.% ZrW2Os were fabricated, the relative density of which ranged from 70% to 80%. Thermal expansion coefficients of the composites decreased as the amount of ZrW2O8 increased, in agreement with the rule of the mixture. The coefficient of thermal expansion of the 4J36/40 vol.%ZrW2O8 composite in 25-100℃ is 0.55 × 10^＋6/℃.

Ab initio study of a Y-doped Σ31 grain boundary in alumina

引用

Science China(Physics,Mechanics & Astronomy) 2008年第11期51卷 1607-1615页

作者： CHEN Jun, XU Yun, CHEN DongQuan & zhang jinglin Laboratory of Computational Physics, Institute of Applied Physics and Computational Mathematics, Beijing 100088, China Laboratory of Computational Physics Institute of Applied Physics and Computational Mathematics Beijing China

The atomic structures and energetics of clean and Y-doped general grain boundary (GB) Σ31/(0001) models in α-Al2O3 are studied by a series of high precision ab initio calculations. A large supercell with 700 atoms and periodic boundary conditions is adopted for undoped and Y-doped GB with different substitution sites and con-centrations. It is shown that Y atoms preferably segregate to the central column of the 7-member Al ring. This is explained as more favorable bond formation for Y in this position and lower GB energy. The calculated GB formation energy for the clean and Y-doped cases is respectively 3.99 and 3.67 J/m2. On the average, the GB region in Σ31 has a slightly lower charge density than the bulk crystalline region. In addtition, the GB induces a long ranged asymmetric electrostatic potential distri-bution on each side of the grain boundary.

RB and/or lattice degeneration were found in 62 eyes(33.88%). The prevalence of RB and/or lattice degeneration was similar between men and women(P=0.344>0.05). There was no statistical difference between the pseudophakic eyes and phakic eyes(P=0.138>0.05). All of the RB and/or lattice degeneration were located near or anterior to the equator.
