A field experiment was carried out at the research station of College Agriculture, University Anbar, for spring season 2021-2022 to study effect adding organic fertilizer and spraying with zinc sulfate on two cultivars Solanum tuberosum L. The as a factorial within design completely randomized sectors (RCBD); first factor included composting transactions ten Control treatment, chemical fertiliz...
Cell surface heparan sulfate proteoglycans facilitate uptake of growth-promoting polyamines (Belting, M., Borsig, L., Fuster, M. M., Brown, J. R., Persson, L., Fransson, L.-A., and Esko, J. D. (2002) Proc. Natl. Acad. Sci. U. S. A. 99, 371-376). Increased polyamine uptake correlates with an increased number of positively charged N-unsubstituted glucosamine units in the otherwise polyanionic hep...
N-Acetylgalactosamine-6-sulfate sulfatase from human placenta was purified 33,600-fold using beta-N-acetyl-D-galactosamine 6-sulfate-(1----4)-beta-D-glucuronic acid-(1----3)-N-acetyl-D-[3H]galactosaminitol 6-sulfate as the substrate. This enzyme is an oligomer with a molecular mass of 120 kDa and consists of polypeptides of 40 and 15 kDa. The 15 kDa polypeptide is a glycoprotein. This purified ...
the enzyme pgalactosidase from a mutant strain of a. niger uv-5 was partially purified using ammonium sulfate and acetone. the saturation range of 60-80% ammonium sulfate was found to yield 60.5% enzyme recovery with 2.4 fold purification. acetone precipitation at enzyme: acetone ratio of 1 : 1.5 brought about a higher yield i.e. 68% and three-fold purification. the combined procedures of 1.5 v...
BACKGROUND Indoxyl sulfate, a uremic toxin, is accumulated in the serum of chronic kidney disease (CKD) patients, accelerating the progression of CKD. In CKD rat kidney, the expressions of nuclear factor (erythroid-derived 2)-like 2 (Nrf2) and its related genes are downregulated. AST-120, an oral sorbent, reduces serum indoxyl sulfate and slows the progression of CKD. The present study aimed to...
The structures of a series of large oligosaccharides derived from acharan sulfate were characterized. Acharan sulfate is an unusual glycosaminoglycan isolated from the giant African snail, Achatina fulica. Oligosaccharides from decasaccharide to hexadecasaccharide were enzymatically prepared using heparin lyase II and purified. Capillary electrophoresis and gel electrophoresis confirmed the pur...
The hydrothermal sediments of Guaymas Basin, an active spreading center in the Gulf of California (Mexico), are rich in porewater methane, short-chain alkanes, sulfate and sulfide, and provide a model system to explore habitat preferences of microorganisms, including sulfate-dependent, methane- and short chain alkane-oxidizing microbial communities. In this study, hot sediments (above 60°C) cov...
abstract to study the effects of different levels of n, mn and zn on yield and quality of pomegranate fruit a factorial experiment based on complete randomized block design with 18 treatments and three replications was conducted in behshahr city, mazandaran province, in 2009.investigated treatments were include: nitrogen, manganese, zinc. fertilizer source for nitrogen was urea and three rates ...
بررسی عناصر روی و منیزیم بر خصوصیات زراعی و جوانهزنی بذر گندم نان (Triticum aestivum L. cv. Sivand)
In order to study the effect of zinc and magnesium on agronomic and seed germination traits of wheat (Sivand cultivar), the current study was carried out at Mahidasht Agricultural Research Station in Kermanshah over the years 2012 and 2013. The experiment was conducted as factorial based on completely randomized block design with three replications. The treatments consisted of four levels of zi...
