Degradation of a water-soluble polyphosphazene, poly[di(carboxylatophenoxy)phosphazene], disodium salt (PCPP) has been studied in aqueous solutions at elevated temperature. This synthetic polyelectrolyte is of interest as vaccine adjuvant and its degradability constitutes an important component of its safety and formulation stability profiles. The degradation process is manifested by a gradual ...

Protein changes induced by salinity stress were investigated in the roots of the salt-sensitive rice cultivar Taichung native 1. We found eight proteins to be induced and obtained partial sequences of one with a molecular mass of 15 kilodaltons and an isoelectric point of 5.5. Using an oligonucleotide probe based on this information, a cDNA clone, salT, was selected and found to contain an open...

CONTEXT Colonoscopy is currently the gold standard method to examine the colon, the rectum and the terminal ileum. In order to perform the colonoscopy, it is necessary to clean the bowel and use medications that are generally poorly tolerated by the patients. OBJECTIVE Compare the tolerability, acceptability, safety and efficacy of two solutions used for intestinal preparation for a colonosco...

We have synthesized a series of Ln(III)-containing polyethylene glycol conjugates and studied the structural and electronic properties of these complexes. These studies demonstrate that polyethylene glycol can be used to fine-tune water-exchange rates of Ln(III)-containing polyaminopolycarboxylate-type complexes; this control is desirable in developing Ln(III)-containing contrast agents for mag...

Large populations of larvae, required for many behavioral assays are difficult to be obtained by individual brush picking from the growth medium. Polyethylene glycol was found as a suitable replacement of sucrose, for density separation. Polyethylene glycol is a non-physiological agent and was found to have no adverse effect on olfactory response of the larvae.

bHLH (basic helix-loop-helix) transcription factors play important roles in the abiotic stress response in plants, but their characteristics and functions in tartary buckwheat (Fagopyrum tataricum), a flavonoid-rich cereal crop with a strong stress tolerance, have not been fully investigated. Here, a novel bHLH gene, designated FtbHLH3, was isolated and characterized. Expression analysis in tar...

OBJECTIVE The objective of this study was to evaluate in an analytical and descriptive manner the evidence published so far on the use of polyethylene glycol (PEG), with or without electrolytes, in the management of functional constipation and the treatment of fecal impaction. METHODOLOGY Search on MEDLINE, EMBASE and Cochrane databases until May 2016 of all publications adjusted to the follo...

Water is essential for plant growth and development. Water deficiency leads to loss of yield and decreased crop quality. To understand water transport mechanisms in plants, we cloned and characterized a novel tonoplast intrinsic protein (TIP) gene from soybean with the highest similarity to TIP2-type from other plants, and thus designated GmTIP2;3. The protein sequence contains two conserved NP...

Positively charged (cetylpyridinium chloride), negatively (sodium dodecyl sulfate), and non-charged (polyethylene glycol) surfactants are used as potential foulant in reverse electrodialysis systems supplying seawater river freshwater. Fouling tendency of the foulants to ion-exchange membranes is investigated terms adsorption by electromigration, electrostatic attraction, macromolecule interact...
