青藏高原东部玉树隆宝蛇绿混杂岩中早二叠世放射虫的发现及其地质意义

报道了采自青藏高原东部玉树隆宝蛇绿混杂岩硅质岩岩块中的放射虫化石.该放射虫组合包括Latentifistula crux Nazarov et Ormiston,Pseudoalbaillella scalprata scalprata Holdsworth et Jones,Pseudoalbaillella scalprata rhombothoracata Ishiga,Pseudoalbaillella sakmarensis(Kozur)等.该放射虫组合属于Pseudoalbaillella scalprata rhombothoracata带,该带可以进行全球对比,地质时代为早二叠世.放射虫动物群与可可西里、滇西等地的古特提斯放射虫组合一致,它指示了玉树早二叠世存在深水沉积盆地.     

Bt防治栗实象甲的试验

Bt(Bacillus thuryingieusis)已成为大规模生产和运用的生物杀虫制剂，通过试验，发现湖北康欣实业有限公司生产的生绿Bt悬浮剂在给定施用范围内稀释800倍杀灭栗实象甲效果最好。     

用共沉淀法合成烧绿石型氧化物Y_2Sn_2O_7的过程研究

本文用 TG—DTA,IR,Raman 和 XRD 等手段研究了共沉淀法合成烧绿石型复合氧化物 Y_2Su_2O_7的过程.实验结果表明,溶液中 Y~(3+)和 SnCl_6~(2-)离子可能同时沉淀,各自形成微晶,随后相互作用形成复合胶体微晶,形成共沉淀的初始产物 YSn_2.它的 X 射线衍射是非晶态的.对YSn_2进行热处理时,Y 和 Sn 的氧化物发生固体反应.最后生成烧绿石型复合氧化物 Y_2Sn_2O_7粉晶.     

论生物基因组的起源和进化

通过分析核基因组、线粒体基因组和叶体基因组的大小与结构，发现这三种基因组教师阴“小基因组”和“大基因组”的形式及与之对应的结构特点，认为它们各自的祖先都是通过分别与“小基因组”和“大基因组”相应的两种途径进化成成为现象核（类核）基因组、线粒体基因组和叶绿体基因组，发展了生物基因组起源和进化的统一模式。

处理助剂厂废水有F2和H2菌株的分离鉴定

从助剂厂废水和生活污水流经的污泥中分离出Ｆ２和Ｈ２菌株，经鉴定Ｆ２为荚膜红假单胞菌，Ｈ２为泥生绿硫菌。讨论了Ｆ２和Ｈ２菌株特征及功能，初步认为它们对助剂厂废水具有高效降解作用。     

Regulation of BMP4 on the proliferation and differentiation in SVZa neural stem cells

The neural stem cells in the anterior subventricular zone (SVZa) mainly generate the progenitors that will differentiate into neurons, and along a highly circumscribed migratory access Rostral migratory stream (RMS), they migrate to the olfactory bulbs (OB). To understand the effects of BMPs on SVZa neural stem cells, in this study BMP4 at various concentrations was used to induce SVZa neural stem cells, and the living cell labeling using BMP4 promotor conjugated with red fluorescence protein showed the expression of BMP4 dynamically. The results demonstrated that low BMP4 doses (1-5 ng/mL) promoted while high doses (10-100 ng/mL) inhibited the proliferation of SVZa neural stem cells, and BMP4 promotedneuron differentiation in the early stage (1-3 d), howeverm, it inhibited the neuron commitment after 4 d. Noggin, the antagonist of BMP4, blocked the physiological effects of BMP4. In OB, BMP4 is mainly to accelerate the progenitors to withdraw from the cell cycle and trigger the differentiation, and in RMS, it promotes the proliferation of committed progenitors and not differentiation, further in SVZa, BMP4 enhances astrocyte commitment.

A novel long-chain acyl-derivative of epigallocatechin-3-O-gallate prepared and purified from green tea polyphenols

Lipophilic tea polyphenols (LTP) were prepared by catalytic esterifieation of green tea polyphenols (GRIP) with hexadeeanoyl chloride. A novel long-chain aeyl-derivative of epigalloeateehin-3-o-gallate(EGCG) was first isolated from purification of LTP by high-speed eountereurrent ehromatography (HSCCC)using a solvent system composed of n-hexane-ethyl acetate-methanol-water ( 1 : 1 : 1 : 1, v/v) . The moleeularstructure of the acyl-derivative, Epigallocatechin-3-O-gallate-4‘-O-hexadeeanate , was elucidated by meansof elemental analysis, IR, 1H-NMR and MS spectra.
