Intercellular communication between dorsal root ganglion cells and colonic smooth muscle cells in vitro

This study demonstrates that the use of high field 1H NMR spectroscopy permits individual detection of phosphatidylcholine and sphingomyelin molecules at the surface of native low density lipoprotein (LDL) particles. Distinct behaviour was observed for the choline head group -N(CH3)3 resonances of these different phospholipids revealing preferential immobilisation for phosphatidylcholine. This suggests the existence of reversible and irreversible phosphatidylcholine-apolipoprotein B interactions and is consistent with microdomain formation at the surface monolayer of LDL. The novel resonance assignment and results show that 1H NMR can provide efficient and practical means for future studies on the structure and dynamics at the LDL surface.     

Cortisone-induced osteoporosis: effects on bone adenylate cyclase

The majority of patients with soft tissue or bone sarcomas of the upper extremity can be treated today with limb-saving procedures using combined modality therapies. For patients with a tumor in the shoulder area, sometimes an interscapulothoracic amputation is the only radical surgical treatment. However, in selected cases, in which the tumor does not involve the neurovascular bundle, a limb-sparing alternative might be the Tikhoff-Linberg resection. Normal function of the hand and forearm, with reasonable function of the elbow, can be maintained by this procedure. Four case histories are reported.

纳米材料对PBT合成的催化性能研究

用溶胶－凝胶法制备TiO2及TiO2/SiO2复合纳米材料，作为PBT（聚对苯二甲酸丁二酯）合成的催化剂，与现在普通使用的催化剂钛酸丁酯进行了比较和研究。结果发现，TiO2/SiO2复合纳米材料催化性能最好，纳米TiO2次之。     

Adsorption of 117mSn(Ⅳ)-EDTMP on hydroxyapatite and collagen

Some organic phosphines labeled with 117mSn(Ⅳ) have been provedpromising for imaging and pain palliation of bone tumor. In this paper, a prelimi-nary investigation on the adsorption characteristics of EDTMP (ethelenediaminete-tramethylene phosphoric acid) labeled with 117mSn(Ⅳ) on HA(hydroxyapatite) andcollagen, and an investigation on the adsorption mechanism of 117mSn(Ⅳ)-EDTMPon HA was presented.``     

具有减少辨识参数的随机多变量极点配置自适应控制器

本文提出了一种新的限制输出个数减少随机多变量自适应控制中辨识参数的方法，并给出了减少辨识参数的极点配置自适应算法。虽然采用ｎ个输入１个输出的减少辨识参数的模型来设计控制器，但所提出的控制器能够保证被控系统的几个输出跟踪参考输入信号，仿真结果表明，所提出的方法是成功的。
