Lipocalin-2 Regulates Hippocampal Microglial Activation in Poststroke Depression

Background and Purpose: Microglia play important role in poststroke depression (PSD), however, the exact mechanism was still unclear. The purpose of the study was to study the mechanism of microglial activation in PSD.Methods: 24 rats were randomly divided into three groups: the PSD group (n = 10), the poststroke (PS) group (n = 7), and the sham group (n = 7). Primary hippocampal microglia were isolated and cultured, and recombined LCN2 protein was used to stimulate the cultured microglia. The protein expression of Iba1, P38 MAPK and PP38 MAPK was analyzed by western blotting; the LCN2 expression was measured by RT-qPCR, the serum LCN2 level and the NO level were analyzed by ELISA.Results: …

An Exploration of Organizational Assimilation Among State-Owned, Private-Owned, and Foreign-Invested Enterprises in China

This study explores organizational assimilation in Chinese organizations. To reflect the Chinese context more accurately, the present study compared employees working in three different kinds of organizations: state-owned enterprises (SOEs), private-owned enterprises (POEs), and foreign-invested enterprises (FIEs). Data collected from 220 full-time employees were analyzed using multiple regression analysis. Regression analyses demonstrated that employees’ level of organizational assimilation was significantly influenced by organizational type: Employees in SOEs reported the highest level and employees in FIEs reported the lowest level of organizational assimilation. peerReviewed

Novel route in the synthesis of MCM-41 containing framework aluminum and its characterization

Abstract Mesoporous molecular sieve MCM-41 with incorporated structural aluminum (Al-MCM-41) was prepared by hydrolysis of a solution of tetraethoxysilane and aluminum isopropoxide in the presence of ammonia as a catalyst. This method provides Al-MCM-41 of different Si/Al ratios from 13 to 297 corresponding to 0.3–7 mol% Al within an hour. X-ray diffraction and nitrogen adsorption measurements showed that the Al-MCM-41 prepared by this method had a highly ordered structure of pore arrays. Most Al atoms in these samples were incorporated tetrahedrally in the MCM-41 structure, which gave rise to cationic sites in the framework.
