به منظور ارزیابی درون شیشه ای ژنوتیپ های سیب زمینی برای تحمل به خشکی آزمایشی به صورت فاکتوریل در قالب طرح کاملاً تصادفی در 6 تکرار در آزمایش اول و چهار تکرار برای آزمایش دوم اجرا شد. فاکتور اول عبارت بود از: گیاهچه های حاصل از بذور حقیقی چند ژنوتیپ سیب زمینی (آگریا، کایزر، cip-994001، گرانولا، ساتینا و دیاموند) و فاکتور دوم در آزمایش اول، سطوح مختلف peg (صفر، 2، 4، 6، 8 و 10 میلی مولار) و در آزم...
AIM To evaluate the complications associated with pegging of porous hydroxyapatite orbital implants. METHODS Complications associated with pegging were retrospectively reviewed from the charts of 100 of 133 patients with hydroxyapatite implantation from 1993 to 2000. RESULTS 48 (48%) of the 100 hydroxyapatite implanted patients who had undergone pegging were found to have problems with thei...
avoid from catch by the reticuloendothelial system (RES). It has been clarified that the prolongation of liposome circulation in the blood and passive targeting to the tumor was achieved by PEG modification of the liposomal surface. In terms of their physicochemical properties by PEG modification, many studies have examined the interaction between the prolonged circulation time of liposomes and...
BACKGROUND PEG-based laxatives are considered today the gold standard for the treatment of constipation in children. PEG formulations differ in terms of composition of inactive ingredients which may have an impact on acceptance, compliance and adherence to treatment. We therefore compared the efficacy, tolerability, acceptance and compliance of a new PEG-only formulation compared to a reference...
Polyethylene glycol (PEG) inhibited aggregation during refolding of bovine carbonic anhydrase B (CAB) through the formation of a nonassociating PEG-intermediate complex. Stoichiometric concentrations of PEG were required for complete recovery of active protein during refolding at aggregating conditions. For example, a PEG (Mr = 3350) to CAB molar ratio ([PEG]/[CAB]) of 2 was sufficient to inhib...
Methoxypolyethylene glycols of 1900 daltons (PEG-1900) or 5000 daltons (PEG-5000) were covalently attached to bovine liver catalase using 2,4,6-trichloro-s-triazine as the coupling agent. Rabbits were immunized by the intravenous and intramuscular routes with catalase modified by covalent attachment of PEG-1900 to 43% of the amino groups (PEG-1900-catalase). The intravenous antiserum did not yi...
Sphingopyxis terrae, and Sphingopyxis macrogoltabida strains 103 and 203, can degrade polyethylene glycols (PEGs). They differ in the following respects: (i) different substrate specificities (chain length) of assimilable PEG, (ii) PEG-inducible or constitutive PEG-degradative proteins, and (iii) symbiotic or axenic degradation of PEG. S. terrae was able to incorporate PEG 6000, but strain 103 ...
BACKGROUND [color=black]Bowel preparation is an important factor for an optimal outcome of colonoscopy. Recently, polyethylene glycol (PEG) solution has been in common use for bowel cleansing for colonoscopy, but some patients are intolerant of PEG because of taste or volume. A low-volume PEG administered with ascorbic acid solution (PEG-Asc) was designed to improve tolerability, but the admini...
Polyamide-6 (PA6) submicron-sized spheres are prepared by two steps: (1) anionic ring-opening polymerization of ε-caprolactam in the presence of poly(ethylene glycol)-block-poly-(propylene glycol)-block-poly(ethylene glycol)(PEG-b-PPG-b-PEG) and (2) separation of PA6 spheres by dissolving PEG-b-PPG-b-PEG from the prepared blends. The PA6 microspheres obtained are regular spherical, with diamete...
فردی که قصد سرمایه گذاری در سهام عادی را دارد، ابتدا لازم است ارزش ذاتی آن سهم را تعیین کرده، سپس با قیمت بازار مقایسه کند. روش برآوردی ارزشیابی قیمت به درآمد، قیمت سهام یک شرکت را به صورت محصولی از سود آن شرکت برآورد می کند. در سال های اخیر، معیار دیگری به نام نسبت peg، به عنوان ابزار شناسایی سهام های مطلوب پدیدار شده است. نسبت peg به صورت ضریب قیمت به سود سهم تقسیم بر نرخ رشد مورد انتظار آن ...
