This study was performed to investigate the glomerular permeability alterations responsible for the microalbuminuria occurring in endotoxemia and during anaphylactic shock. In anesthetized Wistar rats, the left ureter was catheterized for urine collection while, simultaneously, blood access was achieved. Endotoxemia was induced by lipopolysaccharide (LPS) from Escherichia coli, and glomerular p...

The performances of two-phase polymer-liquid PEBAX®/polyethylene glycol (PEG) and three-phase polymer-liquid-solid PEBAX®/PEG/MWNT thin film composite membranes for CO2 and CH4 permeation were studied. The effect of temperature and MWNT/PEBAX® ratio on single gas (CO2 and CH4) permeability was investigated. The permeat...

Angiotensin II-mediated vascular brain inflammation emerged as a novel pathophysiological mechanism in neurogenic hypertension. However, the precise underlying mechanisms and functional consequences in relation to blood-brain barrier (BBB) integrity and central angiotensin II actions mediating neurohumoral activation in hypertension are poorly understood. Here, we aimed to determine whether BBB...

objectives: civil rights may cover different aspects of citizens’ lives. all the members of the society should have equal access to the public facilities and public transportation system. barriers and obstacles in society may limit the accessibility of these facilities to the disabled people. methods: this article contains a part of the results in a phenomenological study of the disability righ...

new edible composite films formed from salep (orchis mascula) and 10%, 20%, and 30% (w/w) oleic acid were prepared by emulsification with the aim of improving the water vapor barrier and mechanical properties of the film. as oleic acid concentration increased up to 30% (w/w), oxygen permeability (27%), elongation at break (86%) and thickness (2%) of salep films increased significantly and the t...

Am J Physiol Renal Physiol 296: F242–F248, 2009. First published November 12, 2008; doi:10.1152/ajprenal.90263.2008.—This study was performed to investigate the glomerular permeability alterations responsible for t...

UNLABELLED Parkinson's disease (PD) is the second most common neurodegenerative disorder of aging. The pathological hallmark of PD is neuronal inclusions termed Lewy bodies whose main component is alpha-synuclein protein. The finding of these Lewy bodies in the intestinal enteric nerves led to the hypothesis that the intestine might be an early site of PD disease in response to an environmental...

pedestrian streets as one type of urban public spaces have an important role in improving the quality of urban life. in iran, planning and designing of pedestrian streets is in its primary steps. in spite of starting this approach in iran, and designing several pedestrian streets, there are still not organized studies about quality assessment of pedestrian streets. as a result, the strength and...

materials and methods liposomes were prepared by thin film method using soya lecithin and cholesterol. physicochemical characteristics of the liposomes such as, particle size, drug encapsulation efficiency were determined. also, drug release and in vitro skin permeability through rat skin were evaluated using franz diffusion cells. results the results showed that the maximum drug encapsulation ...
