Dopamine and CAMP-regulated Phosphoprotein(DARPP-3.)是脑内新纹状体等重要核团的神经元内存在的一种具有多方面信息调节与整合作用的蛋白质。多巴胺、谷氨酸等神经递质与相应受体结合后,使DARPP-3.的3.-苏氨酸等的磷酸化状态发生改变,继而影响PP-1、PP2.等重要磷酸酯酶的活性,使神经元内从各种途径获取的信息得以整合,神经元的生理功能及其控制的行为发生改变。DARPP-3.的功能与多种神经递质及其受体密切相关,其功能可用基因敲除技术进行探究。

采用四种标准煤样和模型化合物(WK11离子交换树脂及其Na和Ca类型),在3.℃～60℃对比研究煤的吡啶气相吸附等温线和影响其吸附行为的因素。模型化合物结果表明:吡啶能断开WK11中的固有氢键,形成更强的吡啶羧基官能团氢键,Na或Ca型WK11由于无法与吡啶形成氢键,因此吸附量很小,并几乎无溶胀现象。四种煤样的吡啶吸附结果表明:由于煤化程度和结构的不同,至少有两种类型的吡啶吸附等温线。同时,煤的吡啶吸附总量并不仅取决于在吸附过程中形成的氢键数量,而且也受其它特殊作用力的影响,这种影响对于高阶煤尤其显著。

兹格塘错是位于藏北高原腹地的一个封闭型湖泊,其湖泊变化过程可直接反映区域的气候变化。为了探讨该区域全新世的气候与环境变化过程,在湖泊中心水深3.m处钻取了一支深72.cm的沉积岩芯,对沉积岩芯的碳酸盐和可溶盐含量进行分析,其结果反映了全新世期间湖泊水体退缩与扩张、水质的浓缩与淡化的过程,揭示了区域气候的干湿变化;指出兹格塘错全新世以来一直处于碳酸盐演化阶段,碳酸盐含量共出现六次明显低值时期,分别为(1)9.3.***.P.、(2.8.3.***.P.、(3.6.0～***.P、(4)4.7～***.P.、(5)3.1～***.P.、(6)0.6～***.P.;而氯离子和硫酸根含量总体很低,且变化趋势几乎一致。碳酸盐和可溶盐含量变化所反映出的湖面波动与环境变化得到了其他资料较好的支持,同时又显示了区域的差异性。

In 2.02. a workshop on Arabidopsis research in china was held in Shanghai, when a small group of chinese plant scientists was working on this model species. Since then, we have witnessed the rapid growth of Arabidopsis research in china. This special issue of Journal of Inte-grative Plant Biology is dedicated exclusively to the Fourth Workshop on Arabidopsis Research in china, scheduled on November 3., 2.05, in Beijing.

The surface and bottom waters samples were collected from six locations in Xiamen western sea. The quantified estimation of bacterial production (H-3.thymidine method) and observation of bacterial heterotrophic activity (C-14-glucose method) have been made in order to have a better understanding of the role of marine bacteria and their activities. The results showed that the mean value of bacterial heterotrophic activity was 9 X 10(8) cells/(L. h) in the surface waters and 2.6 X 10(8) cells/(L. h) in the bottom waters. The mean value of bacterial production was 3. X 108 cells/( L. h) in the surface waters and 7.1 X 10(8) cells/(L. h) in the bottom waters. The relationship between bacterial production, heterotrophic activity, PCC and DOC measured during this survey were discussed. The good understanding of the relationship between bacteria activity and total coliform was addressed.

The bimetal-bearing (CePt or LaPt) 12.tungstophosphoric acid (H3.W12.40 (PW)) catalysts supported on dealuminated USY zeolite (DUSY) were prepared by impregnation and characterized by XRD, BET, IR, and H2.chemisorption. Their catalytic activities were tested in the hydroisomerization of n-heptane with a continuous atmospheric fixed-bed reactor. After the steam treatment combined with the acid leaching, as well as the supporting with PW and the bimetals, the DUSY support retains the Y zeolite porosity and the PW well keeps its Keggin structure in catalysts. The doping of Ce into the catalysts enhances the dispersion of Pt on the catalyst surface. The Pt-bearing PW catalysts doped with Ce or La, especially Ce, exhibit much higher catalytic activity and selectivity than the catalysts without dopants at lowered reaction temperatures. At the optimal reaction conditions, i.e., the reaction temperature of 2.0℃ and WHSV of 1.4 h1, the catalyst with a Pt loading of 0.4%, PW loading of 10% and a molar ratio of Ce to Pt of 15:1 shows a conversion of n-heptane of 70.3. with a high selectivity for isomerization products of 94.1%.

Silica glasses doped with Bi2.3.microcystallite was prepared by the sol-gel process. Photoinduced second harmonic generation (SHG) was observed in the glass when it was irradiated with intense 1.06 mum and frequency doubled laser beams from a mode-locked Nd: YAG laser. It was found that the signal intensity increased with the irradiating time and approached a saturation gradually. The effect may be explained reasonably by the DC field model.
