BACKGROUND Adhesions follow abdominal surgery with an incidence as high as 95%, resulting in invalidating complications such as bowel obstruction, female infertility, and chronic pain. Searches have been performed for a safe and effective adhesion barrier; however, such barriers have impaired anastomotic site healing. The primary aim of this study was to investigate the effect of a new adhesion...

An experiment was conducted to investigate the effects of the resin solid content, catalyst content, and pH value obtained by the addition of two kinds of catalysts on the gel time of a urea–formaldehyde (UF) resin. Upon the addition of ammonium chloride, the pH value of the resin mixture decreased to 7 but not significantly further because of the limited free formaldehyde in the system. The pH...

this articles is comprised of two parts: a) an experimental investigation on the behavior of an acrylic gel under dc electric field and b) a physico - mathematical description.a) gel rods made of poly [acrylamide-co-bisacrylamide] were partially hydrolyzed to different extents at ph 12 by teteramethylethylene diamine. equlibrium properties of the resulting gels rods (water content, number of ca...

In this work, we present a home-made two-dimensional (2-D) CCD imaging system for the monochromatic densitometry of plane gels and its application to the imaging and densitometry of chlorophyll (Chl)-containing proteins separated by non-denaturing polyacrylamide gel electrophoresis. The monochromatic imaging of separated green bands at the wavelengths corresponding to their absorption band incr...

The effect of carbon nanofibers (CNFs) on the electrical properties of Poly(vinylidene fluoride-hexafluoropropylene) (P(VdF-HFP)) based gel polymer electrolytes has been investigated in the present work. The length and diameter ranges of CNFs used in the present work are 5-50 μm and 200-600 nm respectively. The nanocomposite gel polymer electrolytes have been synthesized by solution casting tec...

A basic protein has been isolated from pig brain. The purification procedure consisted of repeated extractions with chloroform-methanol (2: 1 v/v), 10% sodium chloride, and dilute hydrochloric acid. The pH 2.4 to 2.6 fraction obtained from the repeated acid extraction was further purified by pH and (NH&SO4 fractionation, Sephadex G-100 gel filtration, and chromatography on Amberlite IRC-50 with...

Microsponge containing ketotifen drug with three different proportions of ethyl cellulose and drug were obtained successfully using quasi-emulsion solvent diffusion method. These formulations were studied for particle size and physical characterization. These microsponges enriched gel formulation were prepared by using 2 and 3 % w/w of SCMC and studied for viscosity, pH, gel strength, spreadabi...

Cysticercosis caused by Taenia solium metacestodes is a worldwide public health problem. Important progress in the development of effective and practical vaccines against this disease has been made. In this study, the promising T. solium oncospheral vaccine candidate named TSOL18 antigen was produced in a 5-liter fermentor. During the process of fermentation, the pH of the culture was always ke...

The aim of the present investigation is to develop topical gel and cream formulations of psoralen for enhancing its transport through the skin, with the goal to shorten the delay between drug application and UVA irradiation. In our first studies, oil-in-water (O/W) creams of psoralen (0.05% concentration) were prepared using Apifil (PEG-8 Beeswax) and Plurol Stearique WL 1009 as emulsifying age...
