Cross-talk has been shown to occur between the immune system and bone metabolism *** the present study,we investigated the impact of CD4^(+)CD25^(+)Foxp3^(+) regulatory T(Treg)cells on osteoclastogenesis and bone *** cells that were isolated and purified from peripheral blood mononuclear cells(PBMCs)of healthy adults inhibited both the differentiation of osteoclasts(OCs)from human embryo bone marrow cells(BMCs)and the pit formation in a dose-dependent *** cell cocultures,the production levels of both interleukin-10(Il-10)and transforming growth factor-beta 1(TGF-β1)were proportionally upregulated as the ratio of Treg cells to BMCs was increased,and the inhibition of OC differentiation and bone resorption by Treg cells was completely reversed by anti-Il-10 and anti-TGF-β1 *** of BMC and Treg cell cocultures with 17β-estradiol(E2)at concentrations between 10^(-7) and 10^(-9) mol/l suppressed OC differentiation and bone resorption more efficiently than it did in cultures of BMCs alone;this enhanced suppression occurred via the stimulation of Treg cell Il-10 and TGF-b1 *** data suggest that Treg cells suppress OC differentiation and bone resorption by secreting Il-10 and TGF-β1.E2 enhances the suppressive effects of Treg cells on OC differentiation and bone resorption by stimulating Il-10 and TGF-β1 secretion from these ***,Treg cell-derived Il-10 and TGF-b1 are likely involved in the regulation of E2 on bone metabolism and represent potential therapeutic targets for the treatment of postmenopausal osteoporosis(PMO).

The influence of overcoating layers of dialkylglycerylether-β-glucosides(A)1,2O-dialkylglycerylethers(B) and arachidic acid (C20) on the fluorescence of the squaraine dye(SQ) and C20 mixed film were investigated by fluorescence and time-resolved fluorescence measurements. An apparent increase in fluorescence intensity for three layer mixed film of SQ and C20 were obtained by overcoating A in comparison with the small change fluorescence intensity for SQ dye mixed film by overcoating B or C20.

A fire control system of artillery includes a photo-tracker, a computing subsystem and a servomechanism. The photo-tracker outputs moving characteristics of the target during the tracking process, and basing upon this, the computing subsystem makes the computation and outputs shooting elements, and the servo-mechanism controls this piece of artillery to point to the foregoing position of its target in terms of the latter elements.

Polynaphthoxazines-clay nanocomposites were prepared from 1, 5-dihydroxynaphthalene, aniline, formaldehyde and different proportion montmorillonite(MMT) by in-situ reaction in ethanol. Dynamic TGA showed that nanocomposites have delayed decomposition temperatures when compared with pristine polynaphthoxazine indicating the enhancement in the thermal stability.

The hydrolysis rate of Go-bearing ferrous chloride at elevated temperature and the conditions of separation of Co from Fe have been investigated. The hydrolysis process is comprised of the interfacial chemical reaction and the intra-grain diffusion. At the stage under the control of the interfacial chemical reaction, the apparent rate constant k equals to 198.79exp(-80.57/RT). The effects of the temperature, the partial pressure ratio of water vapor and the reaction time on the Co recovery and the separation of Co from Fe are examined. The optimum hydrolysis conditions are determined.

In the theoretical study of numerical solution of stiff ODEs, it usually assumes that the righthand function f(y) satisfy one-side lipschitz condition less than or equal to v(1)parallel to y - z parallel to(2),f : Omega subset of or equal to C-m --> C-m, or another related one-side lipschitz condition [F(Y) - F(Z), Y - Z](D) less than or equal to v'parallel to Y - Z parallel to(D)(2), F : Omega(s) subset of or equal to C-ms --> C-ms, this paper demonstrates that the difference of the two sets of all functions satisfying the above two conditions respectively is at most that v' - v' only is constant independent of stiffness of function f.

Chromium atom-hexane solution prepared in a metal atom reactor was transferred into a solution containing polystyrene in diethylene glycol dibutyl ether at -78 degrees C, followed by gently warming the mixture to 0 degrees C to react for two hows, yielding a brown-green solid product Ultraviolet-visible and infrared spectra showed that the product was a bi- (eta(6)-arene) chromium complex.
