For a 3D C-arm computed tomography(CT) system, actual path of the scanner may deviate from the idea circle geometry because of mechanicalinstability,leading to perturbation artifacts in reconstructed images. In this paper, we proposed a modified FBP method for the perturbed trajectories taking into account 6 perturbation parameters without tassuming any condition to be ideal. The preliminary studies demonstrated that this algorithm can acquire promising reconstruction image quality even when the perturbations are relatively large. The comparison of performances among different perturbation parameters is useful for constructing a C-arm CT system.

The basic premise of high yield in rice is to improve leaf photosynthetic efficiency and coordinate the sourcesink relationship in rice plants. Quantitative trait loci （QTLs） related to morphological traits and chlorophyll content of rice leaves were detected at the stages of heading to maturity, and a major QTL （qLSCHL4） related to flag leaf shape and chlorophyll content was detected at both stages in recombinant inbred lines constructed using the indica rice cultivar 93-11 and the japonica rice cultivar Nipponbare. Map-based cloning and expression analysis showed that LSCHL4 is allelic to NAL1, a gene previously reported in narrow leaf mutant of rice. Overexpression lines transformed with vector carrying LSCHL4 from Nipponbare and a near-isogenic line of 93-11 （NIL-9311） had significantly increased leaf chlorophyll content, enlarged flag leaf size, and improved panicle type. The average yield of NIL-9311 was 18.70% higher than that of 93-11. These results indicate that LSCHL4 had a pleiotropic function. Exploring and pyramiding more high-yield alleles resem- bling LSCHL4 for super rice breeding provides an effective way to achieve new breakthroughs in raising rice yield and generate new ideas for solving the problem of global food safety.

Objective To compare the outcomes of in vitro fertilization （IVF） and intracytoplasmic sperm injection （ICSI） between semen liquefaction and viscosity with normal and abnormal. Methods Semen that liquefied within 60 min and normal viscosity was assigned to the normal group, while semen that unliquefied more than 60 min or high viscosity was assigned to abnormal group. Equal volumes of culture medium were added to abnormal group and normal control group, followed by repeated pipetting, to induce liquefaction. Sperm parameters, fertilization and cleavage rates, good-quality embryo rate, im- plantation rate and pregnancy rate were analyzed. Results The abnormal group ratio was much higher in the ICSI group （30.5%） than in the IVF group （21.9%）（P〈0.05）. The age of the husbands and total progressive motility （PR） sperm in abnormal IVF group were higher than those in normal IVF group （P〈0.05）. Fertilization rate （80.7%） in the abnormal IVF group was higher than that in the normal IVF group （75.6%） and normal control group （P〈0.05）. There were no differences in outcomes of the ICSI patients between the normal and abnormal groups. There was no difference between normal group and normal control group. Conclusion Equal volume of culture media was added to non-liquefied semen may be used to high viscosity and unliquefied semen, and may have a positive effect on fertilization outcomes.

To detect the mammalian target of rapamycin （mTOR） expressed in Cashmere goat fetal fibroblasts （GFb）, mTOR gene was cloned from Inner Mongolia Cashmere goat （Capra hircus） and expressed in Escherichia coli followed by immunizing mice with the purified recombinant protein as an irnmunogen to produce the anti-goat mTOR recombinant polyclonal antibody. Antiserum was collected from the immunized mice after the fifth immunization and its titer was determined with enzyme-linked immunosorbent assay （EliSA）. The results showed that the recombinant polyclonal antibody had a titer 1：200000 and could react with the roTOR expressed in GFb cells with a specific and sensitive affinity. Western blot showed that mTOR expression and phospho-mTOR （Ser 2448） activity were inhibited when GFb cells were treated with CCI-779, an mTOR specific inhibitor.
