Background and Objectives: Cold plasma is an eco-friendly and non-thermal technique, which has become an important technology to change the physical and chemical features of polymers. Recently, cold plasma has been considered in the decontamination and modification of packaging materials in the food industry. Therefore, the objective of this study was to survey the effect of using low-pressure ...
The aim of this study was to assess the feasibility of the Ussing chamber technique for the determination of the jejunal permeability of passively absorbed, high permeability model compounds (acetaminophen and ketoprofen) in different animal species. Additionally, electrophysiological measurements and histological examination of pre- and post-incubation tissue specimens were performed. Apparent...
Information on the water permeability of materials for radioactive waste disposal in geological repositories is essential. High strength and ultra-low concrete (HSULPC) being considered as a material used to package transuranic (TRU) waste. HSULPC would be reinforced by steel fiber increase its tensile toughness, but effect reinforcing unclear. Permeability tests need highly accurate determine ...
Some pharmaceutical excipients are able to modify intestinal permeability, thus influencing drug absorption and bioavailability. The effect of four polyols (mannitol, maltitol, sorbitol xylitol) on the permeability seven active ingredients (API), representing different BCS classes (furosemide, amiloride, atenolol, ranitidine, nadolol, L-thyroxine acyclovir), was investigated using Caco-2 cell m...
abstract the present study was conducted to examine the effect of proficiency on students interaction while carrying out the grammar-based task(s) in collaboration. in particular, the study examines whether the level of proficiency affects the learners’ focus of attention to grammatical and lexical features. the study takes a further step and examines whether there is any difference in the use...
Introduction: Recent studies have reported that the Aloe vera (Aloe barbadensis miller) plant has anti-inflammatory and antioxidant effects. This study evaluated the neuroprotective effects of different doses of Aloe vera extract after traumatic brain injury (TBI) in male rats. Materials and Methods: In this study, 70 male rats were divided into 2 groups; each group consists of 5 of sub-g...
Sulfasalazine is characterized by low intestinal absorption, which essentially enables its colonic targeting and therapeutic action. The mechanisms behind this low absorption have not yet been elucidated. The purpose of this study was to investigate the role of efflux transporters in the intestinal absorption of sulfasalazine as a potential mechanism for its low small-intestinal absorption and ...
Abstract: Minoxidil, a pyrimidine derivative (2, 4-diamino-6-piperidinopyrimidine-3-oxide) is the only topical medical treatment with proven efficacy for the treatment of Androgenetic alopecia that shown low skin penetration and bioavailability. The main aim of this research was to investigate the effect of some permeation enhancers on the in vitro skin permeability of minoxidil . Minoxid...
