Cobalamin metabolism and function were investigated at the levels from transcobalamin II (TCII) receptor to the cobalamin-dependent enzymes, methionine synthase and methylmalonyl-CoA mutase, in a methionine-dependent (P60) and a methionine-independent (P60H) glioma cell line. Using P60H as reference, the P60 cells cultured in a methionine medium had slightly lower TCII receptor activity and nor...
The subcellular distribution and posttranslational modification of human chromatin assembly factor 1 (CAF-1) have been investigated after UV irradiation of HeLa cells. In an asynchronous cell population only a subfraction of the two large CAF-1 subunits, p150 and p60, were found to exist in a chromatin-associated fraction. This fraction is most abundant during S phase in nonirradiated cells and...
Advanced glycation endproducts (AGEs) are derivatives of nonenzymatic reactions between sugars and protein or lipids, and together with AGE-specific receptors are involved in numerous pathogenic processes associated with aging and hyperglycemia. Two of the known AGE-binding proteins isolated from rat liver membranes, p60 and p90, have been partially sequenced. We now report that the N-terminal ...
Introduction: The characteristics of a suitable restoration material is having acceptable mechanical properties, protecting teeth against decay and ease of use in clinics. Diet can affect properties of restorative materials in the mouth. Since amongst important properties of composite restorations are mechanical properties such as hardness, the aim of this study was evaluation of the effect of ...
این تحقیق به منظور بررسی اثر پارامترهای دمای هوای ورودی به خشک کن، رطوبت نهایی دانه و نوع رقم بر کیفیت خواص تبدیلی برنج (درجه سفیدی، درصد شکستگی، ضریب تبدیل، درصد ترک و زمان خشک شدن)، بر روی یک دستگاه خشک کن بستر سیال مجهز به سامانه تنظیم دما انجام شد. پارامتر دمای هوای ورودی در چهار سطح 40، 45، 50 و 55 درجه سانتی گراد، رطوبت نهـایی در سه سـطح 10-8، 12-10 و 14-12 درصد بر مبنای خشک و نوع برنج در...
پلیمرهای آمیدی کاربردهای زیادی در صنایع مختلف دارند. این پلیمرها در صنایع کاغذسازی به طور کلی به عنوان زلالساز در تصفیه آب و پساب، ماندگارکننده و پلیمر مقاومت خشک بهکار میروند. در این تحقیق پلیآکریلآمید گلیاکسالدار شده (G-PAM) به عنوان رزین مقاومت تر موقت در شرایط مختلف سنتز و کارایی آن در بهبود مقاومتهای خشک و تر کاغذ با رزین مقاومت تر پلیآمیدوآمین اپیکلرو هیدرین (PAE) تجاری مقا...
The aim of this study was to determine the degradation resistance of three new formulations-silorane-, Ormocer- and dimer-acid-based materials-and compare them to the traditional dimethacrylate-based materials. One silorane- (Filtek P90, P90), one Ormocer- (Ceram-X, CX), one dimer-acid- (N'Durance, ND) and two dimethacrylate-based (Filtek P60, P60; Tetric Ceram, TC) materials were investigated....
The influence of reversible protein phosphorylation on nucleosome assembly during DNA replication was analyzed in extracts from human cells. Inhibitor studies and add-back experiments indicated requirements of cyclin A/Cdk2, cyclin E/Cdk2, and protein phosphatase type 1 (PP1) activities for nucleosome assembly during DNA synthesis by chromatin assembly factor 1 (CAF-1). The p60 subunit of CAF-1...
Expression of the iap gene of Listeria monocytogenes encoding a major extracellular protein (p60) was analyzed. Different start sites for transcription of the iap gene were identified by primer extension analysis in L. monocytogenes and in a recombinant Escherichia coli clone. The mutant RIII of L. monocytogenes represents a member of the frequently occurring L. monocytogenes R mutants, which f...
During a critical period of postnatal age sensory experience has a profound effect on maturation of visual cortical wiring. Electrophysiological evidence is indicating a substantial effect of visual deprivation on the visual cortical response properties. In this study we evaluated effect of light deprivation during a limited time of postnatal age on two aspects of spatial (working and reference...
