This study was undertaken to have a better understand for the process and the underlying mechanisms to limit macrophage activation and population of activated macrophages.A comprehensive kinetics of cytokine production was performed in murine peritoneal macrophages recovered from Balb/c mice at various time during the course of an intraperitoneal injection with thioglycollate (TG).The expression of cell surface molecules such as MHC-Ⅰ,MHC-Ⅱ,B7-1 and B7-2 of these macrophages were also determined by flow *** present findings of our research suggested that the population of activated macrophages and the activation of macrophages (including cytokines production and expression of cell surface functional molecules) were strictly controlled during inflammation *** is one of the important mechanisms to retain the host *** & Molecular Immunology.2004;1(1):57-62.

The critical zone(CZ) represents the intersection of the biosphere with the atmosphere, hydrosphere and *** the hydrological processes and human impact factors on the CZ is fundamental to sustainable water resources management for agroforestry. Transpiration(T) is an important component of terrestrial evapotranspiration(ET), and understanding the time lag(TL) between vegetation transpiration and meteorological factors can improve our knowledge of the mechanisms of vegetation adaptability to a changing environment. However, the controlling factors on the TL remain poorly understood. Therefore, the objective of this study is identifying the temporal dynamics of key controlling factors on the TL, using a typical deciduous broad-leaved tree species(Zenia insigins Chun) of CZ in subtropical humid karst regions. This species is used as an example to explore the characteristics of the TL between SF(sap flow) and hydro-meteorological forcing. Sap flow in these 6 trees was monitored using the thermal dissipation probes(TDP). Results showed that:(1) the peak of diurnal sap flow generally lagged behind PAR but preceded Ta(air temperature), RH(relative humidity) and VPD(vapor pressure deficit), with the mean TL of-67.4 min(PAR), 90.5 min(Ta), 91.6 min(RH) and 92.9 min(VPD), respectively;(2) TL had no significant relationships with the daily mean meteorological factors and soil moisture, but was highly(R^2>0.66) correlated to CRs(changing rates of meteorological factors) in the morning;(3) At seasonal scale, the sap flow rate and TL both were controlled by the seasonality of precipitation and temperature. Overall, the seasonality of the TL was caused by plants' high water loss and strongly active physiological response in hot seasons, leading to close stomata earlier than in cold seasons;(4) The reason why CRs proposed can explain the TL better than mean values of metrological factors is that the CRs considered the distribution and change processes of metro

为了探究圆柱绕流形成的涡街对水滴的变形、聚结过程的影响,本文运用相场方法,建立了在圆柱绕流、静电场耦合作用的水滴变形和聚结的二维模型。在相同流速和水滴尺寸的模型中分别讨论了静电场、圆柱绕流、静电场与圆柱耦合作用等三种情况。结果表明,在边界条件相同的条件下,圆柱绕流的聚结效率比静电场的聚结效率高,且聚结后形成大水滴形状更趋近于圆形,在静电场和圆柱绕流耦合作用的情况下水滴聚并效率更高,且可以阻止高电场强度下水滴破裂。

AIM To evaluate the validity of LLT in prevention and therapy of acute graft versus host disease and to clarify the underlying mechanisms. LLT is a new compound derived from triptolide, which is the major immunosuppressive fraction of Tripterygium wilfordii Hook. F (TWHF). Studies in vitro and in vivo demonstrated that LLT had potent immunosuppressive activities. Here we tested the immunosuppressive effects of LLT in murine allogeneic bone marrow transplantation (BMT) and investigated the mechanisms underlying its suppressive effects. METHODS LLT was administered to recipients in BALB/cA→C57BL/6 murine BMT model, in which donor and recipient differ at major and minor histocompatibility *** and weight change were recorded in recipients after alloBMT. Spleen size, chimerism and splenic T cell subpopulation were analysed by using flow cytometry.

飞行模拟器是用于飞行训练的主要设备,其模拟飞行的逼真度是影响训练质量的关键,而模拟飞行的逼真度取决于使用的洗出算法,现在最常用的是经典洗出算法,但存在一些缺点。针对经典洗出算法存在的加速度信号丢失和相位误差等问题,结合模糊控制对经典洗出算法进行优化,实现洗出算法的实时动态调整,对高通加速度通道进行信号补偿,最后用Simulink建模对两种算法进行仿真对比,验证优化后洗出算法的优异性。验证结果表明:优化后的洗出算法有效地解决了速度信号丢失和相位误差暗示的问题,同时能够提高飞行模拟器的模拟逼真度。
