A series of water soluble PEG based hyperbranched polymers were successfully synthesized by homopolymerization of poly(ethylene glycol) diacrylate (PEGDA) (Mn 1⁄4 575 and 700 g mol 1 respectively) via vinyl oligomer combination. The homopolymerization of diacrylate macromers underwent a slow vinyl propagation combined with a polycondensation by coupling of reactive oligomers. At a high initiato...

BACKGROUND AND PURPOSE Transport of urea across the blood-brain barrier is increased during postischemic cerebral reperfusion in the piglet. Ischemia/reperfusion also has been observed to increase apparent superoxide anion generation on the surface of the brain. The present study was designed to address the hypothesis that the increased transfer of urea into the brain after ischemia/reperfusion...

Abstract Hydrogels have emerged as leading candidates to reproduce native extracellular matrix. To provide structures and functions similar tissues in vivo, controlled porosity vascular networks are required. However, fabrication techniques introduce these still limited. In this study we propose stereolithography a technique achieve 3D using water-based solvents only. A printable hydrogel is fo...

THE USE of polyethylene glycol (PEG) in preservation solutions has been associated with a decreased incidence of rejection in clinical and experimental transplantation. Using the isolated perfused rat liver model, we found that PEG, when added to phosphate-buffered sucrose solution (PBSL), provided improved liver preservation. A direct comparison of three different molecular configurations of P...

The sensitivity of non-replicating McCoy cells pretreated with polyethylene glycol for the isolation of Chlamydia trachomatis from clinical specimens and for the growth of a laboratory strain was compared with the sensitivity of untreated non-replicating cell cultures. The concentration of polyethylene glycol in different solutions and the time of addition to the cell culture medium were critic...

We studied polyethylene glycol 6000 precipitation of lipoproteins other than high-density lipoproteins, before cholesterol is estimated in the supernate. Other lipoproteins in the supernatant fractions were detected by using rocket immunoelectrophoresis. A polyethylene glycol concentration of 75 g/L in the final mixture appeared to be optimal, and results agreed with those obtained by ultracent...

background and objective: given the widespread use of paraffin in the treatment of constipation in chil-dren and the possibility of long duration of drug use and the risk of drug leakage, the risk of urinary infection in these patients is considerable. the aim of this study was to determine the association between leakage of paraf-fin and the presence or exacerbation of the urinary infection an...

conclusions there was no significant lower recurrence rate of constipation with peg and lactulose combination therapy over peg alone. therefore, changing treatment from lactulose plus peg to peg alone would result in better compliance of patients for long-term therapy and would be cost effective. results the response rate to treatment was 70% in group i and 87% in group ii (p value 0.003). recu...

Background This study aimed to determine effects of synbiotics on treatment of functional constipation in children aged 2-10 years old. Materials and Methods This randomized single blind clinical trial study carried out on children who had functional constipation based on the Rome III criteria. The  polyethylene glycol + synbiotic group (P+S group, n=38)received the synbiotic with polyethylene ...

BACKGROUND Polyethylene glycol is commonly used to manage constipation and is available with or without electrolytes. The addition of electrolytes dates back to its initial development as lavage solutions in preparation for gastrointestinal interventions. The clinical utility of the addition of electrolytes to polyethylene glycol for the management of constipation is not established. The object...
