查询词典 samples

Simultaneously 15 samples of normal nephric tissue were used as control.The sections from these samples were subjected to immunohistochemical analysis with antibodies directly against uPA and PAI-1 by LSAB method. In this study we adopt semiquantitative analysis to determined the expression of these molecules , and utilized the relevant data processing and statistical analysis to evaluate the correlation between their expression and the clinicopathological features of RCC.Results: 1. The positive rate of uPA and PAI-1 of uPA in RCC were 72%(36/50)and 56%(28/50), respectively.But in control group there was nearly

The results show that all aluminum anodizing sludges were slightly neutral to acidic and mainly consist of more than 50% Al2O3; the similar total contents of Cu, Pb, Zn, Ni, Cd, and Cr in the 7 samples were found, namely, the concentrations of Pb, Cd were relatively lower, but that of Cu, Zn, Ni, and Cr were higher; the leaching tests indicate that all the samples were classed as nonhazardous wastes; but each of metals in the sample shows very different leaching behavior, possibly depending on their total contents and the final pH of leachates.

结果表明，铝型材污泥属于中性偏酸性物质，主要由Al2O3组成，含量在50%以上。各试样中Cu、Pb、Zn、Ni、Cd及Cr的总含量的分布趋势基本是一致的，其中Pb、Cd的含量较低，Cu、Zn、Ni及 Cr的含量较高。浸出毒性试验表明铝型材污泥属于非危险废物，但污泥中各重金属的浸出特性又各自不同，可能主要与它们在试样中的总含量和浸出液的最终pH值有关。

The sample particles studied in this project include human red blood cells, osmotically swollen into a micro-sphere, with and without treating with N-ethylmaleimide, and at different temperatures, as well as liposomes with different DOPC/cholesterol ratio (1:1 vs.1:3) For spherical RBCs, smaller deformation were observed in samples at room temperature with NEM treatment and samples at 42 ℃without NEM treatment, compared with the deformation of the control set, namely, RBCs at room temperature without NEM treatment.

这可能是由於42 ℃为红血球细胞骨架Spectrin的型态转换温度，Spectrin由tetramer转换成dimer。推测此温度及药物作用下对Spectrin的型态转换可能造成类似的效果。同时以自行合成DOPC/胆固醇比例(1：1)及(3：1)之微脂粒重覆上述之形变实验，发现两种组合比例微脂粒形变率的差异在误差范围内。

In order to efficiently collect information and tissue samples of pangolins rescued by residents around Taiwan, we assisted in designing and executing a wildlife rescue system for the Formosan Pangolin (Manis pentadactyla pentadactyla). Data and samples collected from this system were analyzed to evaluate its efficiency in providing information for pangolin conservation. This study also examined genetic variability and structure across pangolin populations in Taiwan by using mtDNA sequences of left domain of control region and the partial cytochrome-b gene. Implication of the results from these analyses in pangolin management and conservation was discussed.
