分子筛结构和无定形结构中Ti-O-SiO_3键的IR特性

在对用ＸＲＤ表征确证分属于ＴＳ－２分子筛和无定形ＴＳ氧化物（简称ＡＴＳ）结构的一系列样品进行红外表征时，首次发现在分子筛骨架与无定形表面都存在Ｔｉ－Ｏ－ＳｉＯ３健，但这两者在红外上是可区分的，前者作为骨架钛振动带出现在９６２．５～９６６．７ｃｍ－１处，而后者作为非骨架钛振动带则出现在９４５～９５６ｃｍ－１处，即后者明显发生了红移．分子筛骨架振动带（１２２６，５５６ｃｍ－１）强弱对其Ｔｉ－Ｏ－ＳｉＯ３带的位置影响不大，比较而言骨架带弱的约有２．０ｃｍ－１的红移．苯酚羟基化结果表明在分子筛骨架上的Ｔｉ－Ｏ－ＳｉＯ３活性位上苯酚羟基化生成邻苯二酚和对苯二酚；而处于无定形表面的非骨架Ｔｉ－Ｏ－ＳｉＯ３活性位上只生成邻苯二酚

转美洲拟鲽抗冻蛋白基因(afp)番茄D4代植株可溶性蛋白分析

对转美洲拟鲽抗冻蛋白基因（afp）的第四代番茄及其对照经低温处理后，对幼苗叶片组织可溶性蛋白进行聚丙烯酰胺凝胶电泳分析和紫外吸收法测定含量。发现转基因各组经低温诱导后的可溶性蛋白均比对照明显增加，聚丙烯酰胺凝胶电泳图谱发生变化。其中A-Ⅲ区电泳谱带迁移率加快，C区和B区语带染色加深．说明导入的afp基因已经表达，并使番茄获得抗寒性。     

适用于我国小麦品质育种的SDS—PAGE方法

本文根据多年来实验室工作的经验，采用国产的仪器设备和药品，提出了在182mm×95mm的凝胶上，一次可装载100个样品，每次点样只需1．5－2μl，用于HMW麦谷蛋白亚基分析的SDS—PAGE方法。该方法具有分辨率高，经济性好，简单易行的特点。特别适于小麦育种计划中对大量品系进行HMW麦谷蛋白亚基分析及利用“半粒法”进行HMW麦谷蛋白亚基分析。     

多元插值

多元插值问题，始终是数值分析中的一个重要问题。本文利用Ｗ２＾１（Ｄ）空间的再生核Ｒ（Ｍ，Ｍ‘）得到了一个二元插值公式，此公式具有：１．对任意无限加密的节点系，插值过程一致收敛，２．每增加一个节点，插值误差在Ｓｏｂｏｌｅｖ范数意义下单调下降。３．并且，插值公式只需在原有的基础上增加一项。

Effect of hydrogen peroxide on the binding of Merocyanine 540 to human erythrocytes

The fluorescent dye Merocyanine 540 (MC540) is often used as a probe to monitor the molecular packing of phospholipids in the outer leaflet of biomembranes. In a previous study we showed that the increased staining of erythrocytes with a perturbed membrane structure was mainly due to an increase in the fluorescence yield of cell-bound MC540, rather than to an increase of the number of bound molecules. Erythrocytes and ghosts exposed to continuous fluxes of H₂O₂ exhibited pronounced lipid peroxidation. Further, red blood cells subjected to this form of oxidative stress also showed increased staining with MC540. It appeared that this was caused by a strong increase in binding of MC540, together with a slight red shift of the fluorescence emission maximum and a small increase in the fluorescence yield of bound MC540. The changed MC540 binding characteristics were not observed when lipid peroxidation was suppressed by the presence of the antioxidant BHT in the incubation medium. However, open ghosts exposed to H₂O₂ showed no increase of MC540 binding, excluding a direct involvement of lipid peroxidation. Measurement of fluorescence emission spectra and gel filtration studies showed that MC540 can bind to H₂O₂-exposed hemoglobin. Experiments with erythrocytes lysed in hypotonic medium after exposure to H₂O₂ revealed that peroxidation of lipids with H₂O₂ induced a non-specific permeabilization of the plasma membrane to MC540, thereby allowing MC540 to bind to the oxidatively denatured, more hydrophobic hemoglobin. These results indicate that conclusions about packing of phospholipids in the outer leaflet of the membrane based on increased MC540-staining should be drawn with care.
