The subject of this study is the synthesis glycolysates from recycled poly (ethylene terephthalate) (PET) by depolymerization using diethylene glycol (DEG) in presence catalyst FASCAT 4100. resulting glycolysate was then treated with maleic anhydride and finally 2-octanol to obtain a 2-EtHex/MA/DEG/PET/EG/MA/2-EtHex plasticizer. characterization obtained plasticizer performed infrared spectrosc...

Aqueous solutions of iron oxide nanoparticles (NPs) stabilized by poly(maleic acid-alt-1-octadecene) (PMAcOD) modified with the 5,000 Da poly(ethylene glycol) (PEG) or the short ethylene glycol (EG) tails were analyzed by small-angle X-ray scattering (SAXS). Advanced SAXS data analysis methods were employed to systematically characterize the structure and interactions between the NPs. Depending...

The toxicities of ethylene glycol (EG) and ethylene glycol monoethyl ether (EGEE) were studied in Fischer 344/N rats and B6C3F1 mice. In a 13-week study, EG was administered in feed to groups of 10 rats and 10 mice of both sexes at dose levels of 0 (control), 0.32, 0.63, 1.25, 2.5 and 5.0%. Kidney/body weight ratios were elevated in the 2.5 and 5.0% dose groups of male and female rats relative ...

The primary goal of bioadhesive controlled drug delivery is to localize a delivery device within the body to enhance the drug absorption process in a site-specific manner. An important contributor to good adhesion is the presence of molecular adhesion promoters such as polymer-tethered structure (e.g., poly(ethylene glycol) chains grafted to crosslinked networks) or even linear chains which are...

The electrodeposition of copper onto Au(111) from Deep Eutectic Solvents (DESs) type III has been studied by cyclic voltammetry. Investigations were carried out with mixtures choline chloride (ChCl) and ethylene glycol (EG) or trifluoroacetamide (TFA). eutectic compositions temperatures determined differential scanning calorimetry (DSC). For the ChCl/EG DES, a ratio 16 : 84 (ChCl:EG) was found ...

In order to compare the survival rate of bovine embryos cryopreserved with different protocols, oocytes obtained from abattoir-derived ovaries were used for in vitro maturation (IVM), fertilization (IVF) and co-culture. Expanded blastocysts were cryopreserved by two slowfreezing [(i) 0.5 and (ii) 1.2°C/min], (iii) one quickfreezing and two vitrification [(iv) ethylene glycol + ficoll + sucrose ...

This article focuses on the molecular modeling of the release of doxorubicin from capsules composed of glucosamine(ethylene glycol) oligomers. Doxorubicin forms micelle structures with glucosamine(ethylene glycol), and the drug release mechanism can be studied through the modeling of oligomeric bond breaking under acidic, neutral, or basic conditions. Under these conditions, the activation ener...

Backgroundand Objective:During the holy month of Ramadan, the number of admissions of patients with renal colic increases. This study was conducted to investigate the effects deprivation of food and water on the urinary crystals formation in the kidneys of rats as an experimental model of Ramadan-type fasting (RTF). Subjects and Method...

Background: Toxic alcohol poisonings are responsible for high mortality and morbidity in Russia. This study was aimed to evaluate the trends of harmful ethanol (EtOH) drinking as well as methanol (MeOH), isopropanol (IPA) and ethylene glycol (EG) poisonings in the Middle Urals region of Russia. Methods: In this retrospective study, the medical records of patients poisoned with MeOH, IPA and EG ...
