OBJECTIVE To determine the permeability of human metaphase II oocytes to ethylene glycol and water in the presence of ethylene glycol, and to use this information to develop a method to vitrify human oocytes. DESIGN An incomplete randomized block design. SETTING A university-affiliated assisted reproductive center. PATIENT(S) Women undergoing assisted reproduction in the Center for Reprod...

Human glycol ether poisonings are sparsely reported in the medical literature. We describe a healthy 22-month-old boy who accidentally drank up to 330 mL of brake fluid containing a 75% bleed of various glycol ethers (5%–50% polyethylene glycol monomethyl ether, 15%– 40% triethylene glycol monoethyl ether, 1%–30% triethylene glycol monomethyl ether, 1%–25% triethylene glycol monobutyl ether, 1%...

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...

background: there are varieties of purification techniques for separation of human plasma proteins such as salting out, ion exchange chromatography, and ethanol fractionation. there are limitations for each method, for example in salting out method, the salt has to be removed in an additional step. ion exchange chromatography is difficult for scaling up, and plasma fractionation is a time consu...

The process of molecular recognition is the assembly of two or more molecules through weak interactions. Information in the process of molecular recognition can be transmitted to us via physical signals, which may find applications in sensing and switching. The conventional signals are mainly limited to light signal. Here, we describe the recognition of diols with Cu(1,10-phenlothroline)2SeO4 a...

We previously reported the chemical synthesis of oligonucleotides containing thymine glycol, a major form of oxidative DNA damage. In the preparation of the phosphoramidite building block, the predominant product of the osmium tetroxide oxidation of protected thymidine was (5R,6S)-thymidine glycol. To obtain the building block of the other isomer, (5S,6R)-thymidine glycol, in an amount sufficie...

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 ...

background : staphylococcus aureus strains exhibiting multiple antibiotic resistances are isolated from most communities and hospital infections. treatment of patients with these infections has been difficult. the aim of this study was to detect and extract, the egg yolk immunoglobulin y as a potential source of anti- s. aureus antibody. methods : specific igy was produced by immunizing hens wi...

We investigated the analytical acceptability of ethylene glycol-based control sera by preparing sets of aqueous and ethylene glycol-based specimens that had added uric acid, calcium, creatinine, glucose, urea, sodium, and potassium. Ethylene glycol caused a significant systematic proportional bias in procedures involving dialysis, but had no discernible effect on methods not involving dialysis....
