Polyethylene glycol (PEG) is a non-ionic water soluble polymer that is used as an additive in protein solutions to induce protein crystallization. PEG in dilute solution concentrations and within a molecular weight range, induces an attractive protein-protein interaction. However the strength of this attractive proteinprotein interaction weakens with increasing PEG concentration and molecular w...

Various tannin-complexing agents have been used to study the potential adverse effects of tannins on rumen metabolism. Using a method based on turbidity formation, the binding of various tannin-complexing agents (polyvinyl polypyrrolidone (PVPP), polyethylene glycol (PEG) of molecular weights 2000 to 35,000, and polyvinyl pyrrolidone (PVP) of molecular weight 10,000, 40,000 and 360,000) to tann...

The aim of this study was to determine the effect drought on accumulation and tolerance energy willow (Salix viminalis L. var. ‘Gigantea’) copper (Cu) nickel (Ni) in context phytoremediation potential plant biomass production under adverse water conditions. Drought simulated with polyethylene glycol (PEG-6000. 5%), metals were added at a concentration 1 mM. Plants cultivated greenhouse conditio...

Monomeric prolactin estimate (MRRL) post polyethylene glycol (PEG) precipitation has been added to the RCPAQAP endocrine program in 2022. The noted flagged low performance compared consensus prompted further investigation identify causes. Prolactin testing by Abbott alinity method showed acceptable excluding any analytical issue with assay. PEG preparation procedure was reviewed and confirmed b...

Quercetin is a bioflavonoid compound with low water solubility in both foods and the gastrointestinal tract, which limits exploitation of its health-promoting properties. This study aims to formulate solid dispersions (SDs) quercetin hydrophilic polyethylene glycol PEG matrices, using melt-mixing method, improve dissolution antioxidant activity quercetin. Initially, total Gibbs free energy for ...

The early stages of quinoa germination are sensitive to drought stress. For this purpose, a study entitled the effect selenium in different concentrations on characteristics and some antioxidant enzymes under stress conditions with polyethylene glycol (PEG 6000) was investigated. first experimental factor seed priming (from two sources: sodium selenate nanoparticles: SeNPs ? 33.4 nm) at 0.5, 1....

Abstract Plantago albicans L. (Plantaginaceae) grows in wastelands, slopes, and stony pastures, with dry sun‐exposed soils. Its seeds produce a mucilaginous coat. The main aim of this study was to evaluate intraspecific variation osmotic salinity stress response mucilage production P. seeds. relationships between stress, germination characteristics, expansion were studied eight populations . Se...

Background: Therapeutic and diagnosis properties of radioactive gold nanoparticle (198-AuNPs) cause them to be suitable for detection and treatment of tumors.Objective: Electrical and optical properties of PEG-198AuNPs were examined in this paper. Polyethylene Glycol (PEG)-198 AuNPs can be used for treatment and diagnosis of small intestine tumors.Methods: Wireless fluorescence capsule endoscop...
