BACKGROUND： Nattokinase （NK） is a serine protease enzyme of the subtilisin family. It exhibits a strong fibrinolytic activity. The fibrinolytic enzymes from Bacillus sp. have attracted interest as thrombolytic agents because of their efficiency in the fibrinolytic process including plasmin activation. METHODS： In the present study, VIT garden soil was collected and subjected to isolation process in order to screen for the NK production. Screening for NK enzyme was performed by radial caseinolytic assay. The production of NK enzyme was done in two different production medium for comparative studies. The NK enzyme was purified by gel permeation chromatography. The activity of the purified NK was checked by clot lysis and casein digestion assay. To investigate the structural basis of NK and fibrinogen interaction and also to identify the best binding mode, molecular dynamics and docking studies were performed. RESULTS： Based on the morphological and biochemical characterization, the isolate was identified as Bacillus sp. The overall purification fold of NK was about 3 with the specific activity of 664U/mg and 9.9% yield. Homogeneity of the purified enzyme was analyzed and confirmed by the single band obtained in SDS-PAGE. Molecular weight of the purified protease was estimated as 25 kDa. Purified NK enzyme exhibited 97% of effective clot lysis activity. The NK was docked in to the knob region of the fibrinogen at its binding site using Dock server. A total of 26 residues of fibrinogen and 29 residues of NK constitute the interface region. However, 9 residues offibrinogen （THR238, MET264, LYS266, ARG275, THR277, ALA279, ASN308, MET310, and LYS321） and 8 residues ofNK （GLY61, SER63, THR99, PHE189, LEU209, TYR217, ASN218, and MET222） are involved in intact binding. CONCLUSIONS： A significant amount of NK enzyme was obtained from Bacillus sp. The docking analysis revealed that the NK and fibrinogen adopt an extended binding pattern and interacts with the crucial residues t

Dynamics of the phase-change material GeTe across the structural phase transition

Results of inelastic neutron scattering experinients and ab initio molecular dynamics simulations for GeTe 一 the parent compound of phase-change materials are reported. The inelastic neutron spectra of GeTe powder samples have been determined in the temperature range extending from 300 to 700 K. The phonon peaks undergo thermal shifts resulting from anharmonic effects being weaker for acoustic than optic modes. A small concentration of free charge carries arising from the presence of Ge-vacancies was found not to affect significantly the neutron weighted phonon densities of states of GeTe. The spectral pattern changes qualitatively across the structural phase transition, but the local structure of GeTe remains hardly affected, as confirmed by the analysis of temperature dependence of the pairdistribution function obtained from ab initio molecular dynamics investigations. The present theoretical studies support in a wide extent our experimental observations and also those provided by local probe methods.

Performance of the health system in China and Asia as measured by responsiveness

引用

Health 2011年第10期3卷 638-646页

作者： Paul Kowal Nirmala Naidoo Sharon Renee Williams Somnath chatterji 不详

Objectives: To examine differences in health system responsiveness across different sectors in China and to compare to other Asian countries. Methods: The World Health Survey was implemented in a nationally representative sample in China and 10 additional Asian countries from 2002-2003. Face-to-face interviews were conducted to gather health care utilization and health systems responsiveness data. Results: Overall health system responsiveness in China was better for the inpatient than the outpatient health system. Differences were seen by domain, with prompt attention and respectful treatment performing better than the other domains. Differences in responsiveness were seen by socio- demographic characteristics, with women and younger respondents rating inpatient systems, whereas men and higher educated respondents rated outpatient systems, more responsive. Conclusions: As populations age, health care systems will come under more pressures – responsiveness can be used by governments to guide policy and system improvement efforts when resources are limited. In China, reforms might prioritize outpatient system responsiveness.

北京论坛（2011）文明的和谐与共同繁荣--传统与现代、变革与转型

作者： Manas chatterji Binghamton University

The objective of this presentation is to discuss the impact of Globalization on Urban-Regional system in the developing countries. Although the emphasis will be more on the urban sector, some observation will be made on the rural sector since both of them are intricately related. I shall start with urban growth patterns of different cities in Asia, Africa and Latin America vis-a-vis cities in Europe and U.S. More emphasis will be given to World Cities/Mega Cities and the theoretical reasons of the growth and decay of these cities will be given in the framework Paul Krugman's theory of New Geography. Then I shall address the issue of the impact of globalization on the cultural, social, economic and political characteristics of this transformation particularly for developing countries. I shall also discuss how knowledge and information system affects this transformation. Special attention will be paid on inequality and environmental degradation caused in urban center by globalization. Some recommendation will be given how to change the governance, decision making process, institutions and use international and inter regional co-operation to mitigate the negative externality and increase the benefit of globalization I shall refer to some theoretical and quantitative techniques in Urban and Regional Science which can be used for analyzing this transformation and forecasting the future trend.
