Rice glutelin might be mainly controlled by about six major genes according to the expression of glutelin polypeptides. The acidic polypeptide of glutelin could be clearly separated into two groups by peptide mapping and N-terminal amino acid sequence analysis. These two groups were just in accord with the GluA and GluB subfamilies exactly.展开更多

The structural parameters and properties of Nb and Mo characteristic atoms sequences and corresponding characteristic crystals sequences were determined in Nb-Mo alloys system. The electronic structure and physical properties of disordered Nb(1-x)Mox alloys system were calculated according to concentration of characteristic atoms of disordered alloys. The change trend of physical properties is the same as that of electronic structure.展开更多

They can be applied in approximating continuous functions with arbitrary growth order, defined on a finite interval or the whole real axis. The properties of approximation are studied and their asymptotic formulae are presented. These results show that their degrees of approximation are the best among existing operator sequences of Landau type, for example, their degrees of approximation for C 2[0, 1] are O(1/n 2) but corresponding degree of ordinary Landau operators are only O(1/n).展开更多

Eucalyptus camaldulensis is a fast-growing hardwood species with a wide distribution in Iran and can be introduced as appropriatematerial to compensate the wood shortages of the natural forest. Kraft pulping was performed under different cooking conditions and, based on the relations of pulp yield and kappa number, bleachable kraft pulp at screened yield of 43.3% and kappa number of 31.3 was selected for DED (Chlorine Dioxide-Alkaline Extraction-Chlorine Dioxide) bleaching and its bleachability was studied at different kappa factor in D~ stage. The results indicated that the bleachable kraft pulp from this species has high kappa number at acceptable screened yield and to complete the delignification in the bleaching process, higher kappa factor may be needed in DED bleaching sequence. The main reduction in final kappa number and yield loss were observed at kappa factor level of 0.2 but by further increase in kappa factor up to 0.4, more development were observed in optical properties but at lower opacity.展开更多

Methods PDCD5 expression was determined by EnVision immunohistochemical staining in forma-lin-fixed and paraffin-embedded specimens obtained from 12 subjects with NP, 22 with BPH, and 22 with PCa. In addition, PCa cases were classified as low/middle-risk (Gleason sumS7) and high-risk (Gleason sum〉7) on the basis of Gleason grade. Positive expression rates and intensity of PDCD5 protein were observed under light microscope and analyzed with computer imaging technique. Expression of PDCD5 was compared among different prostatic tissues. Results The expression of PDCD5 was significantly lower in tissue of PCa than in tissues of NP and BPH (P〈0.01). However, there was no significant difference in PDCD5 expression between tissues of NP and BPH. In addition, the expression of PDCD5 was further downregulated with the increase of Gleason sum in PCa. Conclusions By downregulating apoptosis, low PDCD5 expression may play an important role in the occurrence and development of PCa. PDCD5 is supposed to have a potential clinical value to be a new predictor of progression and target of gene therapy in PCa.展开更多

This paper presents a fuzzy clustering algorithm based on average link and possibilistic clustering paradigm termed as AVLINK. It minimizes the average dissimilarity between pairs of patterns within the same cluster and at the same time the size of a cluster is maximized by computing the zeros of the derivative of proposed objective function. AVLINK along with the proposed initialization procedure show a high outliers rejection capability as it makes their membership very low furthermore it does not requires the number of clusters to be known in advance and it can discover clusters of non convex shape. The effectiveness and robustness of the proposed algorithms have been demonstrated on different types of protein data sets.展开更多
