Selenium concentration in hair are sorted out into three classes, i.e. low (520 ppb) according to the principle of multiple normal distribution and a map of classification of selenium concentration in hair from children and youngsters in china has been drawn. Selenium insufficiency in relation to Keshan disease and Kashin-Beck's disease is expounded. Geographical differentiation of hair selenium concentrations and its causes are explained.

Fabrication of YBCO superconducting thick films by electrophoresis has been widely reported. However, the value of critical current density (J c) is far from what the practical application requires. The superconducting thick films are obtained using top-seeded melt growth method with different proportional Y2BaCuO5 (Y211) addition. High-pressure oxygen has been used in the annealing process to improve the uniformity of the oxygen content in the superconducting thick films. When 4.mol% Y211 powder is added to the YBa2Cu3O7–5 (Y123) powder,J c for the superconducting thick film by approaches described above reaches 7.008×103 A/cm2 (77 K, 0 T), which is greater than the value ever reported.

关键词： YBCO thick films, electrophoretic deposition, melt-textured.

The soluble HLA-G1 (sHLA-G1) isoform was found to be secreted by trophoblast cells at the matemo-fetal interface, which suggests that it may act as an immunomodulator during pregnancy. In this paper, we reported that GST-sHLA-G1α chain could bind to its receptor ILT-2 on NK92 cells and then the latter recruited Src homology 2 domaincontaining tyrosine phosphatase-1 (SHP-1), which consequently dephosphorylated some important protein tyrosine kinases and blocked the activation of downstream molecules such as MEK and ERK so that the cytotoxicity of natural killer (NK) cells was inhibited. These results indicated that GST-sHLA-G1α chain might be exploited in new immunotherapy strategies aiming at inducing immunotolerance during allograft, xenograft and autoimmune situations. In addition, we found that modification of O-linked β-N-acetylglucosamine (O-GlcNAc) was involved in NK cells’ activating and inhibitory signals. This may provide a novel molecular target for inducing immunotolerance but needs furthe

The structures of Ωω states with spin-parity J=5/2~-,3/2~-,and 1/2~- are dynamically studied in boththe chiral SU(3)quark model and the extended chiral SU(3)quark model by solving a resonating group method(RGM)*** model parameters are taken from our previous work,which gave a satisfactory description of the energiesof the baryon ground states,the binding energy of the deuteron,the nucleon-nucleon(NN)scattering phase shifts,andthe hyperon-nucleon(YN)cross *** calculated results show that the Ωω state has an attractive interaction,and in the extended chiral SU(3) quark model such attraction can make for a Ωω quasi-bound state with spin-parityJ~ρ=3/2~- or 5/2~- and the binding energy of about several MeV.
