Polyethylene glycol (PEG) is a frequently used osmotic laxative that accelerates gastrointestinal transit. It has remained unclear, however, whether PEG affects intestinal functions. We aimed to determine the effect of PEG treatment on intestinal sterol metabolism. Rats were treated with PEG in drinking water (7%) for 2 wk or left untreated (controls). We studied the enterohepatic circulation o...

BACKGROUND Artificial feeding by a percutaneous endoscopic gastrostomy (PEG) tube in patients with dementia has increased since the introduction of the endoscopic method of tube placement. Few studies have documented survival benefit from this intervention. This report reviews our experience with PEG tube placement for feeding patients with dementia. METHODS All consultations for PEG tube pla...

Cancer gene therapy with adenovirus vectors (Adv) is limited to local administration because systemic administration of Adv produces a weak therapeutic effect and severe side effects. Previously, we generated a dual cancer-specific Adv system by using Adv covalently conjugated to polyethylene glycol (PEG) for transductional targeting and the telomere reverse transcriptase (TERT) promoter as a c...

A gold nanoparticle (AuNP)-based colorimetric method was developed for the molecular weight (MW) determination of polyethylene glycol (PEG), a commonly used hydrophilic polymer. Addition of a salt solution to PEG-coated AuNP solutions helps in screening the electrostatic repulsion between nanoparticles and generating a color change of the solutions from wine red to blue in 10 min in accordance ...

Single-walled carbon nanotubes (SWCNTs) involving polyethylene glycol (PEG) and polyethyleneimine (PEI), which contain amines, were produced analyzed using X-ray diffraction (XRD), UV–vis spectroscopy, Raman spectroscopy (RS), transmission electron microscopy (TEM) for the spectral structural analyses of PEG-PEI-SWCNTs. PEG-PEI-SWCNTs demonstrated peaks at 300.98 nm, have a broad peak 2θ = 23.5...

Feeding-related adverse events after percutaneous endoscopic gastrostomy (PEG) such as aspiration pneumonia can impede the use of PEG. Percutaneous endoscopic transgastric jejunostomy (PEG-J) using large-bore jejunal tubes with gastric decompression function may improve outcomes by circumventing gastric passage during enteral nutrition and improving drainage of excessive gastric secretions. Thi...

This study prepared shape-memory thermoplastic epoxy (TEP)-polyethylene glycol (PEG) filaments for the first time, and heat-stimuli controllability of shape memory function was innovatively endowed by adding PEG in an environmentally friendly way. regulates glass transition temperature PEG-modified (TEP–PEG) without interfering with polymerization reaction epoxy. The melt spinning TEP–PEG is al...

Foam thin liquid films (TLF) and monolayers at the air-water interface formed by DMPC mixed with DMPE-bonded poly (ethylene glycol)s (DMPE-PEG(550), DMPE-PEG(2000) and DMPE-PEG(5000)) were obtained. The influence of both (i) PEG chain size (evaluated in terms of Mw) and mushroom-to-brush conformational transition and (ii) of the liposome/micelle ratio in the film-forming dispersions, on the int...

Current pegylated interferon-α (PEG-IFN) treatment for chronic hepatitis B (CHB) e-antigen (HBeAg)-positive patients are suboptimal, and effective ways of improving PEG-IFN treatment efficacy are needed.This retrospective cohort study compared the efficacy of a PEG-IFN stepwise optimization treatment (PEG-IFN SOT) strategy with that of a 48-week PEG-IFN standard therapy (PEG-IFN ST) in HBeAg-po...

When liposomes, as a superior drug carrier, are injected intravenously, active liposomes as medicines require polyethyleneglycol (PEG) as a modification tool around the liposomal membrane. PEG modification of a liposome forms a fixed aqueous layer, and the trapping by cells of the reticuloendothelial system (RES) is avoided. Hence, PEG-modified liposomes have long circulation in the bloodstream...
