A method is proposed to estimate the ultimate strength of rectangular concrete-filled steel tubular (CFT) stub columns under axial compression. The ultimate strength of concrete core is determined by using the conception of the effective lateral confining pressure and a failure criterion of concrete under true triaxial compression, which takes into account the difference between the lateral confining pressure provided by the broad faces of the steel tube and that provided by the narrow faces of the steel tube. The longitudinal steel strength of broad faces and that of the narrow faces of the steel tube are calculated respectively due to that buckling tends to occur earlier and more extensively on the broader faces. Finally, the proposed method is verified with experimental results. Corresponding values of ultimate strength calculated by ACI (2005), AISC (1999) and GJB4142-2000 are given respectively for comparison. It is found from comparison that the proposed method shows a good agreement with the experimental results.

Mitochondrial phosphate transporter plays animportant regulatory role in promoting the uptake andtransport of phosphate in plants. In this study, the SlMPT3;1gene, a member of mitochondrial phosphate transporterfamily in tomato, was isolated and transformed into the riceOryza sativa L. ssp. japonica cultivar Kitaake. The SlMPT3;1 islocalized to the mitochondrial membrane and functions incompensating the phosphate uptake in yeast MB192 mutantthat is defective in phosphate transport under Pi deficiency. RT-qPCR showed that the SlMPT3;1 is expressed in all oftomato tissues, but highly accumulated in the young leavesand stems under Pi deficiency. The data demonstrated that atleast two copies of the SlMPT3;1 gene are inserted into therice genome, and the transcripts of the SlMPT3;1 mRNA arehighly accumulated in the roots of the transgenic rice. Theoverexpression of the SlMPT3;1 gene not only promotesphosphate uptake by the roots, but also increases thetranslocation of phosphate from the roots to the shoots in thetransgenic rice. The transgenic rice accumulated morechlorophyll and soluble sugar in the shoots than the wildtype under Pi deficiency. Microassay sequencing showedthat the differentially expressed genes in the transgenic riceare mainly involved in the regulations of biological processand molecular function under Pi deficiency. Further RTqPCRanalyses revealed that the differentially expressedgenes, which are involved in the regulations of the biologicalprocess, cell component, and molecular function, are upregulatedunder Pi deficiency, and exhibit similar expressiontrends to the relative expression folds of these partial differentiallyexpressed genes in the transcriptomic analyses. This studysuggests that the overexpression of the SlMPT3;1 gene promotedthe uptake and transport of phosphate in rice, thus leading to anenhanced increase in tiller number and effective panicle of perplant, and increasing grain yield under Pi deficiency.

Complexes M($C_7H_2NO_5)3H_2O{\cdot}H_2O{\cdot}0.25MeCN$ (M=Ni, Co) were crystallized from the reactions of $Ni(CH_3COO)_2{\cdot}4H_2O\;or\;Co(CH_3COO)_2{\cdot}2H_2O$ with KSCN and 2,6-dicarboxy-4-hydroxypyridine (chelidamic acid). The structures were characterized by X-ray crystallography. The crystal structures of 1 and 2 show a distorted octahedral coordination geometry around the M(II) ions, which are chelated by one nitrogen atom and two oxygen atoms of the chelidamic acid and three water molecules. Complexes 1 and 2 display the hydrogen-bonded 3D framework. The magnetic behavior of 2 exhibits antiferromagnetic interaction.

Although the current glucocorticoids (GCs) treatment for systemic lupus erythematosus (SLE) is effective to a certain extent, the difference in therapeutic effect between patients is still a widespread problem. Some patients can have repeated attacks that greatly diminish their quality of life. This study was conducted to investigate the relationship between HSP90AA2 polymorphisms and disease susceptibility, GCs efficacy and health-related quality of life (HRQoL) in Chinese SLE patients. A case–control study was performed in 470 SLE patients and 470 normal controls. Then, 444 patients in the case group were followed up for 12 weeks to observe efficacy of GCs and improvement of HRQoL. Two single nucleotide polymorphisms (SNPs) of HSP90AA2 were selected for genotyping: rs1826330 and rs6484340. HRQoL was assessed using the SF-36 questionnaire. The minor T allele of rs1826330 and the TT haplotype formed by rs1826330 and rs6484340 showed associations with decreased SLE risk (T allele: PBH = 0.022; TT haplotype: PBH = 0.033). A significant association between rs6484340 and improvement of HRQoL was revealed in the follow-up study. Five subscales of SF-36 were appeared to be influenced by rs6484340: total score of SF-36 (additive model: PBH = 0.026), physical function (additive model: PBH = 0.026), rolephysical (recessive model: PBH = 0.041), mental health (dominant model: PBH = 0.047), and physical component summary (additive model: PBH = 0.026). No statistical significance was found between HSP90AA2 gene polymorphisms and GCs efficacy. These results revealed a genetic association between HSP90AA2 and SLE. Remarkably, HSP90AA2 has an impact on the improvement of HRQoL in Chinese population with SLE.
