Hexylene glycol buffered at pH 6 .4 (7) will preserve microtubules from mammalian brain in homogenates (9) . The observations presented here show that hexylene glycol is better than ethanol or sucrose for preserving the microtubules ; nevertheless, the concentration of microtubules decreases with time even in the presence of hexylene glycol . Cold, autolysis, divalent cations, and mitotic spind...

The possibility of using glycol chitosan to obtain stabilized liposome containers for doxorubicin delivery is demonstrated. The dissociation constants of the liposome complexes with glycol chitosan (3.4 × 10–4 and 1.10 × 10–5 depending on the aggregation state of the liposomes) are determined. It is shown that the formation of liposome complexes with glycol chitosan has a significant prolongati...

The use of polyethylene glycol 4000 as a non-absorbable, continuously fed faecal marker is described. The intestinal handling and transit of polyethylene glycol is compared with that of chromium sesquioxide and barium sulphate. Polyethylene glycol is an acceptable non-absorbable faecal marker for calcium, phosphorus, and fatty acids, and has several features which commend its use in preference ...

An accurate mass determination method utilizing electrospray ionization mass spectrometry is described for analysis of several different types of phosphoramidites that are extremely acid-sensitive compounds. An earlier method, which applied a LiCl/acetonitrile system, was extended for this special application by using polymeric standards including poly(ethylene glycol) (PEG), poly(ethylene glyc...

Materials: Tetraethylorthosilicate (TEOS, 98%), aqueous ammonia (28%) were purchased from Sinopharm Chemical Reagent Co. Ltd.. Carbon black (99.5%, 30 nm) was purchased from Aladdin Co. Ltd.. Ethylene glycol (EG, 99%) and ethanol (99.9%) were purchased from J&K Co. Ltd.. Poly(ethylene glycol) methacrylate (PEGMA, Mn=360) and poly(ethylene glycol) diacrylate (PEGDA, Mn=700) was purchased from Si...

Ethylene glycol, methanol, and diethylene glycol are readily available in many household and commercially available products. While these alcohols are relatively nontoxic themselves, their acidic metabolites are toxic and can result in significant morbidity and mortality. Herein we report a lethal case of massive ethylene glycol ingestion in a suicide with a record high level (1254 mg/dL) and i...

DGBA 1 Diethylene Glycol n-Butyl Ether Acetate (CAS# 124-17-4) (Synonyms: Butyl carbitol acetate; Butyl diglycol acetate; 2-(2-Butoxyethoxy)ethanol acetate; 2(2-Butoxyethoxy)ethyl acetate; Acetic acid 2-(2-butoxyethoxy)ethyl ester; Butoxyethoxyethyl acetate; Butyl carbitol acetate; Butyl diethylene glycol acetate; Diethyleneglycol monobutyl ether acetate; Diglycol monobutyl ether acetate; Ektas...

Polyethylene glycol (PEG) is widely used, and many biologically active molecules are modified with oligoethylene glycol substituents to enhance their half-lives in circulation. The pervasive use of PEG substituents is partly due to their presumed inertness. Our investigation of formyl peptide receptor (FPR)-mediated chemotaxis reveals that oligoethylene glycol substitution can enhance the abili...

In this research nano particles of bismuth ferrite (BiFeO3) were synthesized by sol-gel auto-combustion route. The effect of water and ethylene glycol solvents were studied on phase constituents, magnetic properties and microstructure of the bismuth ferrite by X-ray diffraction (XRD), scanning electron microscope (SEM) and vibration sample magnetometer (VSM) techniques. XRD resul...
