We evaluated six precipitation methods for high-density lipoprotein cholesterol (HDL-chol) determination: the heparin/Mn2+ precipitation reagent method (Hep), two variants of the phosphotungstic acid/Mg2+ method (Tung-L and Tung-B), the dextran sulfate 50,000/Mg2+ method (Dex), the PEG 6000 method (PEG), and the PEG 6000/dextran sulfate 15,000 (PEG/Dex) method. The Tung-B and PEG/Dex precipitat...

Physiological, metabolic, and genetic changes produced by two plant growth promoting rhizobacteria (PGPR) Pseudomonas sp. (internal code of the laboratory: N 5.12 21.24) inoculated in tomato plants subjected to moderate water stress (10% polyethylene glycol-6000; PEG) were studied. Photosynthesis efficiency, photosynthetic pigments, compatible osmolytes, reactive oxygen species (ROS) scavenging...

HBs vaccines were prepared by three different methods: 1) Heat inactivation (Krugman, et.al 1971)2) Ammonium sulphate precipitation followed by column chromatography (Sephadex G-200) 3) PEG-6000 (polyethylene glycol) precipitation followed by column chromatography using Sephadex G-200. Their efficacy was studied in guinea pigs, and the results compared with commercial Japanese vaccine (Gr...

Cytoplasm contains a large number of macromolecules at extremely high densities. How this striking nature of intracellular milieu called macromolecular crowding affects intracellular signaling remains uncharacterized. Here, we examined the effect of macromolecular crowding on ERK MAPK phosphorylation by MEK MAPKK. Addition of polyethylene glycol-6000 (PEG-6000) as a crowder to mimic intracellul...

Doxazosin mesylate (DXM) sustained release pellets were prepared by an extrusion-spheronization and fluid-bed coating technique. The core pellets containing DXM were prepared by extrusion-spheronization technique, and coated by a fluid-bed coater to control the release of DXM. The factors affecting to properties of pellets, such as diluent content, type and coating level of coating agents and p...

Objective: The study aimed to solubilization of imidazole drugs of interest; ketoconazole (KT) and miconazole nitrate (MN), for enhancement of the water solubility, the dissolution properties and the antimycotic activity of these drugs. Method: Different solid dispersion methods were used to prepare various dispersion systems of KT and MN using polyethylene glycol 4000 (PEG 4000), polyethylene ...

Hydrogen peroxide (H2O2) is a strong oxidant that induces apoptosis of tumor cells in vitro. Here, we investigated the antitumor activity of an H2O2-generating enzyme, D-amino acid oxidase (DAO), and its conjugate with polyethylene glycol (PEG; PEG-DAO). Compared with DAO, PEG-DAO showed improved pharmacokinetic parameters in mice after i.v. injection. PEG-DAO administered i.v. accumulated sele...

تنش شوری از عوامل مؤثر در جلوگیری از جوانه­زنی و استقرار گیاهچه محسوب می­گردد. نمک­ها در روند جوانه­زنی با محدود کردن مقدار آب در دسترس (اثر اسمزی) و یا به سبب صدمات ناشی از ورود یون­ها، در روند متابولیسم (اثر یونی) مؤثر می­باشند. به­منظور بررسی اثر تنش یونی و اسمزی ناشی از وجود نمک در محیط بذر دو گونه cristatum  Agropyronو Agropyron elongatum از محلول­های ایزواسمزی کلرید سدیم (NaCl) و پلی­اتیل...
