BACKGROUND Polyethylene glycol (PEG) is often considered as the first-line treatment for functional constipation in children. Descurainia sophia (L.) Webb et Berth (D. sophia) is a safe recommended medicine in Iranian folk and Traditional Persian Medicine for the treatment of constipation. OBJECTIVES To clinically compare D. sophia with PEG 4000 (without electrolyte) in pediatric constipation...

BACKGROUND Chronic constipation is frequent in children. The objective of this study is to compare the efficacy and safety of PEG 4000 and lactulose for the treatment of chronic constipation in young children. METHODS This randomised, double-blind study enrolled 88 young children aged 12 to 36 months, who were randomly assigned to receive lactulose (3.3 g per day) or PEG 4000 (8 g per day) fo...

A reagent is described for the colorimetric enzymic determination of high-density-lipoprotein (HDL) cholesterol. The reagent can be used with HDL fractions isolated by the various methods of precipitation of low- and very-low-density lipoproteins we investigated. The considerable sensitivity obtained by use of Barham-Trinder's reaction allows the sample/reagent volume ratio to be decreased to 1...

We have developed a reliable radioimmunoassay for testosterone in plasma, polyethylene glycol ("Carbowax 6000") being used to separate antibody-bound and free hormone. Testosteron is separated from interfering steroids, notably dihydrotestosterone, by liquid-liquid partition chromatography on infusorial earth (Celite). The assay is sensitive (9 pg for standards), precise, and accurate. The lowe...

Surface passivation is critical for effective PCR using silicon-glass chips. We tested a dynamic polymer-based surface passivation method. Polyethylene glycol 8000 (PEG 8000) or polyvinylpyrrolidone 40 (PVP-40) applied at 0.75% (w/v) in the reaction mixture produced significant surface passivation effects using either native or SiO2-precoated silicon-glass chips. PCR amplification was achieved ...

Title: Polyethylene glycol vs. sodium phosphate for bowel preparation: A treatment arm meta-analysis of randomized controlled trials

OBJECTIVE The purpose of this study was to look at the development of two in-hand skills of rotation. Three questions were asked: (a) Do boys' and girls' performance differ significantly? (b) Does performance improve with age? and (c) Can periods of rapid improvement with age be seen on the tasks presented? METHOD The in-hand manipulation skill of rotation was measured in 154 right-handed chi...

This communication reports a new approach to synthesize amphiphilic block copolymers. The copolymers with well-defined structures were synthesized by macromolecular azo-coupling reaction between the diazonium salt of aniline-functionalized PEG and the polymeric blocks with a terminal suitable for the azo-coupling reaction.
