The neuronal p35 activator of Cdk5 is a novel F-actin binding and bundling protein

The neuronal Cdk5 activator p35 is involved in a multitude of neuronal activities, including cytoskeletal organization. We show here that p35 directly interacts with filamentous actin (F-actin) but not with monomeric actin (G-actin). Through binding, p35 induces the formation of actin bundles and stabilizes F-actin against dilution-induced depolymerization. p35 forms intermolecular self-associations, suggesting that p35 cross-links actin filaments into bundles via its intermolecular self-association. p35 dimerization and association with F-actin occur at the N-terminal region that is absent in the calpain-cleaved product p25, indicating that such p35 properties are lost by its truncation induced under neurotoxic conditions. Using p35 phosphorylated by Cdk5 and a mutational approach, we demonstrate that the phosphorylation of p35 promotes its homodimerization and p35-induced formation of F-actin bundles. In addition, the phosphorylation regulates p35 distribution to microtubule and actin cytoskeletons. Together, these observations define a novel function for p35 in cytoskeletal regulation.

Electrochemical processing of spent nuclear fuels: An overview of oxide reduction in pyroprocessing technology

The electrochemical reduction process has been used to reduce spent oxide fuel to a metallic form using pyroprocessing technology for a closed fuel cycle in combination with a metal-fuel fast reactor.In the electrochemical reduction process,oxides fuels are loaded at the cathode basket in molten Li_2O–LiCl salt and electrochemically reduced to the metal form.Various approaches based on thermodynamic calculations and experimental studies have been used to understand the electrode reaction and efficiently treat spent fuels.The factors that affect the speed of the electrochemical reduction have been determined to optimize the process and scale-up the electrolysis cell.In addition,demonstrations of the integrated series of processes(electrorefining and salt distillation) with the electrochemical reduction have been conducted to realize the oxide fuel cycle.This overview provides insight into the current status of and issues related to the electrochemical processing of spent nuclear fuels.

浅谈中学生健美操表现力在教学过程中的培养

表现力是影响中学生健美操表演效果和比赛成绩的重要因素,它具有独立的意义,它是一种无声的体态语言,是对动作和音乐的解释和补充,是内心感受和情感的体验,是通过动作表达出心愿而达到健与美最佳境界的方式,然而在中学生健美操的训练和练习中许多学生都缺乏自我表现力,本文针对中学生健美操表现力的培养方法、途径及对影响中学生表现力的因素和概念进行详细阐述,为在教学过程中有计划、有目的、有步骤地培养学生表现力提供理论依据和具体的实践方法。
