In many human diseases, the presence of inflammation is associated with an increase in the level of reactive oxygen species (ROS). The resulting state of oxidative stress is highly detrimental and can initiate a cascade of events that ultimately lead to cell death. Thus, many therapeutic attempts have been focused on either modulating the immune system to lower inflammation or reducing the dama...

BACKGROUND Adequate bowel preparation is an essential prerequisite for complete mucosal visualization during colonoscopy. Polyethylene glycol (PEG) solutions are commonly used. However the large volume of the solution is often poorly tolerated. Addition of Lubiprostone (LB) could improve the adequacy of standard PEG preparation & reduce requirement. The aims to assess adequacy of PEG preparatio...

BACKGROUND Adequate adjuncts help to reduce the volume of polyethylene glycol-electrolyte lavage solution (PEG-ELS) needed, to ameliorate patient discomfort, and to improve colonic visibility during colonoscopy. This study aimed to assess the effect of Citrus reticulata peel (CRP) as an adjunct to low-volume PEG for colonic preparation. METHODS A total of 1092 health examination examinees rec...

BACKGROUND Standard-volume polyethylene glycol (PEG) gut lavage solutions are safe and effective, but they require the consumption of large volumes of fluid. A new lower-volume solution of PEG plus ascorbic acid has been used recently as a preparation for colonoscopy. AIM A meta-analysis was performed to compare the performance of low-volume PEG plus ascorbic acid with standard-volume PEG as ...

BACKGROUND AND AIMS Seroclearance or seroconversion of hepatitis B surface antigen (HBsAg) is generally considered as the clinical endpoint. The purpose of the present meta-analysis was to evaluate pegylated interferon alpha (PEG-IFNα) with or without lamivudine (LAM) or adefovir (ADV) combination treatment in HBsAg seroclearance or seroconversion with CHB. METHODS Randomized controlled trial...

In order to improve the shoot proliferation rate of ‘Dwarf Cavendish’ banana shoot tip cultures, polyethylene glycol (PEG6000) was employed at concentrations of 2, 4, and 6% (w/v). The medium without PEG was considered as negative control. An increasing of shoot proliferation was achieved in MS medium containing 2% PEG. Furthermore, application of 2% PEG significantly increased the shoot dry we...

Protein chips technology has emerged as a promising tool for screening protein-protein interactions and characterizing the levels of proteins expressed in cells. Novel surface technologies must be improved to satisfy the specific protein orientation on the surface without denaturation, retaining non-fouling character of the surface. In order to construct facile immobilization of protein on the ...

BACKGROUND Since enteral nutrition therapy is the preferred nutritional support for dysphagic patients with a range of diagnoses, PEG has become part of traditional care. However, enteral nutrition with PEG transfers treatment responsibility and activity to the patients and their carers, so the advantages should be discussed. The aim of this study was therefore to investigate patients' experien...

Nanoparticle-mediated gene delivery is a promising alternative to viral methods; however, its use in vivo, particularly following systemic injection, has suffered from poor delivery efficiency. Although PEGylation of nanoparticles has been successfully demonstrated as a strategy to enhance colloidal stability, its success in improving delivery efficiency has been limited, largely due to reduced...

BACKGROUND Percutaneous endoscopic gastrostomy (PEG) is a safe procedure and major morbidity is unusual. However, the number of PEG fed patients is increasing all over the world and complications may become more and more frequent. CASE REPORT We describe a 73 years old woman with persistent vomit after replacement of the standard PEG tube with a Foley catheter. An upper GI endoscopy showed th...
