Glass transition behavior of ternary disaccharide-ethylene glycol-water solutions, in reference to that of the binary combinations, has been investigated towards a better understanding of their cryoprotective ability. In water-deficient solutions, the disaccharides, including trehalose, sucrose and maltose, can associate with more than 100 ethylene glycol molecules to form amorphous complex, on...

The present study was undertaken to investigate the effects of ethylene glycol concentration and time of exposure to equilibration solution on the post-thaw morphological appearance and the in vitro maturation rate of buffalo oocytes. Vitrification solution-I (VS-I) consisted of 4.5M ethylene glycol (EG), 3.4M dimethyl sulphoxide, 5. 56mM glucose, 0.33mM sodium pyruvate and 0.4% w/v bovine seru...

As the number of patients waiting to receive transplants increases, there is a need to explore all possible donation opportunities. In this case report, we describe the transplantation of a liver from a donor who died after ethylene glycol poisoning into a woman with alcoholic liver disease with cirrhosis and associated ascites. Donor management, including ethanol, fomepizol and haemodialysis, ...

Summary Esterases have emerged as important biocatalysts for enzyme-based polyester recycling of poly(ethylene terephthalate) (PET) to terephthalic acid (TPA) and ethylene glycol (EG). Here, we present process modeling, techno-economic, life-cycle, socioeconomic impact analyses an enzymatic PET depolymerization-based process, which compare with virgin TPA manufacturing. We predict that...

Abstract Furan‐2,5‐dimethylcarboxylate (FDMC), along with ethylene glycol (EG), is the key monomer to produce (poly‐(ethylene‐furanoate) (PEF). Noble metal‐based catalysts can convert hydroxymethyl furfural (HMF) FDMC in methanol through liquid phase catalytic oxidative esterification. In this work, performance of Au, Pd and AuPd NPs supported on nanosized nickel oxide (nNiO) have been evaluate...

Ethylene glycol, a common antifreeze, coolant and industrial solvent, is responsible for many instances of accidental and intentional poisoning annually. Following ingestion, ethylene glycol is first hepatically metabolised to glycoaldehyde by alcohol dehydrogenase. Glycoaldehyde is then oxidised to glycolic acid, glyoxylic acid and finally oxalic acid. While ethylene glycol itself causes intox...

This discussion will highlight the following 9 specific points that related to metabolic acidosis caused by various toxins. The current recommendation suggests that alcohol dehydrogenase inhibitor fomepizole is preferred to ethanol in treatment of methanol and ethylene glycol poisoning, but analysis of the enzyme kinetics indicates that ethanol is a better alternative. In the presence of a mode...

This study aims at evaluating and comparing the thermal performance of five different engine coolants employed in an experimental cooling system with a flat-tube louvered-fin automobile radiator. For this purpose, PLC-controlled test was set up. The could maintain temperatures air coolant radiator inlet, speed flow rate required values during tests. tested were pure wa-ter, 30/70 ethylene glyco...

INTRODUCTION Every year about 2.4 million people in USA are exposed to toxic substances. Many of them are children below 6 years of age. Majority of poisonings in children are incidental and related to household products including for example drugs, cleaning products or antifreeze products. Antifreeze solutions contain ethylene glycol and methanol. Treatment of these toxic substances involves e...

BACKGROUND Increasing cell membrane permeability to water and cryoprotectants is critical for the successful cryopreservation of cells with large volumes. Artificial expression of water-selective aquaporins or aquaglyceroporins (GLPs), such as mammalian aquaporin-3 (AQP3), enhances cell permeability to water and cryoprotectants, but it is known that AQP3-mediated water and solute permeation is ...
