世界核心医学期刊文摘（眼科学分册） 2005年第9期1卷 54-55页

作者： Funatsu H. Yamashita H. sakata k. 吴琼 Department of Ophthalmology Diabetes Center Tokyo Women's Medical University 8-1 Kawada-cho Shinjukuku Tokyo 162-8666 Japan Dr.

Purpose: To investigate whether vascular endothelial growth factor (VEGF) or soluble intercellular adhesion molecule 1 (sICAM-1) is related to diabetic macular edema (DME). Design: Retrospective case-control study. Participants: Thirty-three patients who had DME and 13 patients with nondiabetic ocular disease (control group). Methods: Vitreous fluid samples were obtained at the time of vitreoretinal surgery, and the VEGF and sICAM-1 levels in vitreous fluid and plasma were measured by enzyme-linked immunosorbent assay. Main Outcome Measures: Relationship between vitreous levels of VEGF or sICAM-1 and DME. Results: Vitreous levels of VEGF and sICAM-1 were significantly higher in DME patients than in control patients (P kness at the central fovea (P < 0.0001 and P= 0.0005, respectively) Conclusions: We found that both VEGF and sICAM-1 were elevated in the vitreous fluid of patients with hyperfluorescent DME. These results suggest that VEGF and ICAM-1 are related to the increase of vascular permeability in DME patients.

Aqueous-phase reforming(APR)is an attractive process to produce bio-based hydrogen from waste biomass streams,during which the catalyst stability is often challenged due to the harsh reaction *** this work,three Pt-based catalysts supported on C,AlO(OH),and ZrO_(2)were investigated for the APR of hydroxyacetone solution in afixed bed reactor at 225℃and 35 *** them,the Pt/C catalyst showed the highest turnover frequency for H_(2)production(TOF of 8.9 molH_(2)molPt^(-1)min^(-1))and the longest catalyst *** the AlO(OH)and ZrO_(2)supported Pt catalysts,the side reactions consuming H_(2),formation of coke,and Pt sintering result in a low H_(2)production and the fast catalyst *** proposed reaction pathways suggest that a promising APR catalyst should reform all oxygenates in the aqueous phase,minimize the hydrogenation of the oxygenates,maximize the WGS reaction,and inhibit the condensation and coking reactions for maximizing the hydrogen yield and a stable catalytic performance.

在我们对乌龙茶（水仙与毛蟹──是茶树的两种名品种）的香味形成机理作研究的过程中，我们分离并鉴定出了香叶醇、芳樟醇、2-苯乙醇、苄醇、芳樟醇氧化物Ⅰ与Ⅱ（反式-与顺式-芳樟醇3，6-氧化物）的主要醇类香味前驱体（1-7），并与β-樱草糖苷一样的水杨酸甲酯（6-O-β-D-吡喃木糖基-β-D-吡喃糖苷），以酶法水解（用Yabukita栽培种制得的丙酮粉末）得出，随后采用气相色谱与气相色谱-质谱联用分析法。芳樟醇氧化物Ⅳ（顺式-芳樟醇3，7-氧化物）与（Z）-3-己烯醇的香味前驱体（8与9）罕见地分别以6-O-β-D-芹菜呋喃糖基-β-D-吡喃葡糖与β-D-吡喃葡糖的形式被分离出。作为一个初始实验，我们亦认日本绿茶生产用的Yabukita栽培种的新鲜茶叶作提纯并对其特性描述为一种新的糖苷酶（β-樱草糖苷）。这一糖苷酶经证实为与茶叶中醇类香味形成有关系的主要糖苷酶之一。这是迄今为止提纯出的第二个β-樱草糖苷的标样。从新鲜乌龙茶叶（水仙栽培种）中作的糖苷酶的提纯亦完成了一项发现，即樱草糖苷的活性很近似于Yabukita栽培种。

The estimation of residual displacements in a structure due to an anticipated earthquake event has increasingly become an important component of performance-based earthquake engineering because controlling these displacements plays an important role in ensuring cost-feasible or cost-effective repairs in a damaged structure after the *** attempt is made in this study to obtain statistical estimates of constant-ductility residual displacement spectra for bilinear and pinching oscillators with 5%initial damping,directly in terms of easily available seismological,site,and model *** of the available models for the bilinear and pinching oscillators are useful when design spectra for a seismic hazard at a site are not *** statistical estimates of a residual displacement spectrum are proposed in terms of earthquake magnitude,epicentral distance,site geology parameter,and three model parameters for a given set of ductility demand and a hysteretic energy capacity coefficient in the case of bilinear and pinching models,as well as for a given set of pinching parameters for displacement and strength at the breakpoint in the case of pinching model *** proposed scaling model is applicable to horizontal ground motions in the western *** earthquake magnitudes less than 7 or epicentral distances greater than 20 km.
