Dr. Colmar Niederstadt, Department of Internal Medicine, Medical University of Lübeck, Ratzeburger Allee 160, D-23538 Lübeck (Germany) From days 4-18 after intoxication, we repeatedly measured the urinary concentration of immunoglobulin G, albumin, < xi-microglobulin and endogenous creatinine clearance (fig. 1). Ethylene glycol itself is probably not nephrotoxic, but in the metabolism of ethyle...

Background: We describe a case of acute ethylene glycol poisoning following ingestion of antifreeze agent in which serum ethylene glycol and anion gap were serially measured. Patients: A 66-year old man was hospitalized after intentional ingestion of automotive antifreeze. Upon admission, vital signs, mental status, and neurological functions were normal. Initial laboratory tests revealed no se...

We have studied the micellization of surfactants SDS, CTAB and tweens-80 using a series of Ethylene glycol/water and formamide/water mixed solvents using surface tension, viscosity and conductance measurements. The results are compared with those reported in pure water for the same surfactants. The critical micelle concentration (cmc) shifts to lower values upon increasing the ratio of Ethylene...

We report on the protein-resistant properties of glass substrates coated with novel copolymers of 2-aminoethyl methacrylate hydrochloride and poly(ethylene glycol) methyl ether methacrylate (AEM-PEG). In comparison to currently available protein-blocking polymer systems, such as poly-l-lysine-poly(ethylene glycol), silane-based poly(ethylene glycol), and poly(ethylene glycol) brushes prepared b...

Microwave heating is rapidly emerging as an effective and efficient tool in various technological and scientific fields. A comprehensive understanding of the fundamentals of microwave-matter interactions is the precondition for better utilization of microwave technology. However, microwave heating is usually only known as dielectric heating, and the contribution of the magnetic field component ...

graphene oxide was prepared using modified hummers method. stable ethylene-glycol nanofluids containing graphene oxide nanosheets were provided. nd: yag pulsed laser was applied to prepare reduced nanofluids. experimental results revealed that thermal conductivity of the nanofluids is increased with increasing the concentration of graphene oxide (go) in ethylene glycol. the enhancement ratio of...

The lead ferrite (PbFe12O19) nanoparticles were prepared by a simple and short time microwave method. Lead nitrate, iron nitrate nine hydrate, surfactants, and ethylene glycol were used as precursor materials. The effect of surfactants on the morphology and particle size of the magnetic products was investigated. The prepared magnetic products were studied by X-ray diffraction, scanning electro...

We introduce a two-dimensional method for mass spectrometry in solution that is based on the interaction between a nanometer-scale pore and analytes. As an example, poly(ethylene glycol) molecules that enter a single alpha-hemolysin pore cause distinct mass-dependent conductance states with characteristic mean residence times. The conductance-based mass spectrum clearly resolves the repeat unit...

Acute ethylene glycol ingestion classically presents with high anion gap acidosis, elevated osmolar gap, altered mental status, and acute renal failure. However, chronic ingestion of ethylene glycol is a challenging diagnosis that can present as acute kidney injury with subtle physical findings and without the classic metabolic derangements. We present a case of chronic ethylene glycol ingestio...

in this study, the natural convection heat transfer of variable properties al2o3-eg-water nanofluid in a differentially heated rectangular cavity has been investigated numerically. the governing equations, for a newtonian fluid, have been solved numerically with a finite volume approach. the influences of the pertinent parameters such as ra in the range of 103-107 and volume fraction of nanopar...
