The proprotein precursors of storage proteins are post-translationally processed to produce their respective mature forms within the protein storage vacuoles of maturing seeds. To investigate the processing mechanism in vivo, we isolated Arabidopsis mutants that accumulate detectable amounts of the precursors of the storage proteins, 12 S globulins and 2 S albumins, in their seeds. All six muta...
Neurotoxicity of beta-amyloid peptide (A beta) in Alzheimer's disease (AD) is usually thought to arise from the nonspecific effects of high concentrations of A beta on vulnerable neurons, resulting in membrane destabilization and increasing intracellular calcium concentration. This review advances the hypothesis that at early stages of AD, when A beta is present in lower amounts, its ability to...
We report a study of quantum oscillations (QO) in the magnetic torque nodal-line Dirac semimetal $\mathrm{ZrSiS}$ fields up to 35 T and temperature range from 40 K down 2 K, enabling high resolution mapping Fermi surface (FS) topology ${k}_{z}=\ensuremath{\pi}$ (Z-R-A) plane first Brillouin zone (FBZ). It is found that oscillatory part measured signal consists low frequency (LF) contributions (...
امروزه ترکیبات آلاینده آلی بهوسیله فعالیت های انسانی، از راه های متفاوتی تولید می شوند. این آلایندهها بهدلیل ویژگی های جهشزایی، سرطانزایی و سمیت بالایی که دارند برای محیط زیست و موجودات زنده خطرناک هستند. این مواد نسبتاً فرارند و نیمه عمر طولانی دارند لذا تخریب و از بین بردن آلاینده های آلی بهروش هایی که برای محیط زیست مضر نباشد، مهم است. با توجه به کاربرد گسترده زئولیتها در جذب آلاینده...
The catalytic hydrotreatment of humins, the solid byproduct produced from conversion C6 sugars (glucose, fructose) to 5-hydroxymethylfurfural (HMF), using supported Pd@zeolite (Beta, Y, and USY) catalysts with different amounts Pd (i.e., 0.5, 1.0 1.5 wt%) was investigated under molecular hydrogen pressure. highest humins (52.0%) obtained on 1.5Pd@USY catalyst while amount oil (27.3%) in presenc...
here, we report analysis of in vitro and in vivo drug release from an in situ formulation consisting of triamcinolone acetonide (tr) and poly(d,l-lactide-co-glycolide) (plga) and the additives glycofurol and hydroxyapatite nanoparticles (ha). we found that these additives enhanced drug release rate. we used the taguchi method to predict optimum formulation variables to minimise the initial burs...
in this study we introduce the concepts of statistical convergence of order$beta$ and strong $p-$ces`{a}ro summability of order $beta$ for sequencesof fuzzy numbers. also, we give some relations between the statisticalconvergence of order $beta$ and strong $p-$ces`{a}ro summability of order$beta$ and construct some interesting examples.
The presenilin-mediated Notch1 cleavage pathway plays a critical role in controlling pancreatic beta cell fate and survival. The aim of the present study was to investigate the role of Notch1 activation in glucotoxicity-induced beta cell impairment and the contributions of miR-375, miR-30a, and miR-34a to this pathway. We found that the protein levels of presenilins (PSEN1 and PSEN2), and NOTCH...
Cleavage of gentiobiose in cell extracts of gentiobiose-grown Aerobacter aerogenes was dependent on the presence of adenosine 5'-triphosphate (ATP). The enzymes that participate in the overall reaction were shown to be a beta-glucoside kinase, which catalyzes the phosphorylation of gentiobiose with ATP to form gentiobiose monophosphate [6-O-phosphoryl-beta-d-glucopyranosyl-(1 --> 6)-d-glucose],...
