Objectives: Aim of the present work was to investigate the anti-inflammatory, analgesic and antiulcer effects of red seaweed Porphyra vietnamensis (P. vietnamenis). Materials and Methods: Aqueous (POR) and alcoholic (PE) fractions were successfully isolated from P. vietnamenis. Further biological investigations were performed using a classic test of paw edema induced by carrageenan, writhing in...

Optically active bionanocomposite membranes composed of polyester(PE) and cellulose /silica bionanocomposite (BNCs) are a novel method to enhance gas separation performance. Commercially available silica nanoparticles were modified with biodegradable nanocellulose through ultrasonic irradiation technique. Transmission electron microscopy (TEM) analyses showed that the cellulose/silica composite...

In this study, different derivative spectrophotometric methods are proposed for the simultaneous determination of chlorpheniramine maleate (CP), phenylephrine HCl (PE) and phenylpropanolamine HCl (PP) in their ternary mixtures and in pharmaceutical dosage forms. Spectra of single component and ternary mixtures of various concentrations and combinations from zero- to fourth-derivation were obtai...

AIMS The following polymers were developed: polyethylene (PE), a PE and polyethylene oxide (70% PE and 30% PEO; PE + PEO) blend, PE and nisin (PE + nisin), PE, nisin, and EDTA (PE + nisin + EDTA), and PE + PEO with nisin (PE + PEO + nisin). METHODS AND RESULTS Of the polymers tested, PE and PE + PEO did not exhibit any antimicrobial activity against Brochothrix thermosphacta (BT); however, PE...

the data on the effect of ethylene concentration on polymerization rate for several modifications of modern highly active titanium–magnesium catalysts ticl4/mgcl2 are presented. these catalysts differ in titanium content and conditions of support preparation, activities, and the shape of kinetic curves. it is found that the observed order of polymerization rate with respect to ethylene in the r...

This study was aimed to investigate the effects of encapsulated nano- and microparticles of peppermint (Mentha piperita) extract on the growth performance, blood parameters and immune system of broilers under heat stress conditions. In total, 320 one-day-old broilers (Ross, 308) were assigned into 4 experimental treatments: the control, peppermint alcoholic extract (PE, 200 ppm/kg body weight (...

The effects of carboxyacyl phosphatidylethanolamine derivatives (CA-PE) on the physicochemical properties of liposomes were examined from standpoints of zeta-potential, agglutination, phase transition temperature, microviscosity and micropolarity. Absolute zeta-potential of liposomes containing Succinyl-PE or Glutaryl-PE exceeded that of those containing Dodecanyl-PE. The addition of Succinyl-P...

The interdisciplinary nature of complex design poses the challenge of computational burden due to complexity of the problem. In view of this a design methodology has been proposed in this work. The primary goal of the proposed methodology is to simplify and shorten the design process. Within this work a framework is presented in which modelling, multiobjective optimisation and multi criteria de...

this study was conducted to determine the prevalence of pe in patients with v/q scans interpreted as representing a very low probability (vlp) of pe (1-3 small segmental perfusion defects with a normal chest radiograph). an analysis of the entire data set obtained during the pioped study was performed. of the total of 1,359 patients in whom the presence or absence of pe was confirmed, 80 (6%) p...
