Benign pleural mesothelial cells have higher osmotic water permeability than malignant pleural mesothelioma cells and differentially respond to hyperosmolality
(2019)Background/Aims: Cell volume regulation is a critical mechanism for cell homeostasis and depends on the osmotic water permeability (Pf) of the cell plasma membrane. The Pf of human mesothelial cells is unknown although ... -
Brattleboro rats have impaired apical membrane water permeability regulation in the outer medullary collecting duct principal cells
(2016)Vasopressin (AVP) regulates the body salt-water balance. Brattleboro rats carry an AVP gene mutation resulting in a recessive form of central diabetes insipidus, being ideal for AVP deficiency studies. Herein, we studied ... -
Collagen fibril diameter distribution affects permeability of ligament tissue: A computational study on healthy and injured tissues
(2020)Background and objective In a vascular or hypovascular tissues, elements required for maintaining tissue functions are recruited through diffusion, which is highly related with the permeability of the extracellular matrix ... -
Effect of adrenaline on transmesothelial resistance of isolated sheep pleura
(2006)The effect of adrenaline on the transmesothelial resistance (R-TM) of sheep's visceral and parietal pleura was studied using the Ussing chamber technique. Basal transmesothelial resistance of visceral pleura was found to ... -
Effect of endothelin-1 on the transmesothelial resistance of isolated visceral sheep peritoneum
(2007)The mesothelium is part of the peritoneal barrier that manages the water and ion transport essential for peritoneal dialysis (PD) treatment. In addition, it has a central role in the pathogenesis of peritoneal fibrosis and ... -
Effect of macroscale formation of intraluminal thrombus on blood flow in abdominal aortic aneurysms
(2016)A mathematical approach of blood flow within an abdominal aortic aneurysm (AAA) with intraluminal thrombus (ILT) is presented. The macroscale formation of ILT is modeled as a growing porous medium with variable porosity ... -
Effect of micropolar fluid properties on the hydraulic permeability of fibrous biomaterials
(2020)Background and objective: In this work, the effect of the micropolar fluid parameters on the hydraulic permeability of fibrous biomaterials comprised of square arrays of undirectional fibrils is investigated. Methods: ... -
Effect of sodium-potassium pump inhibition by ouabain on the permeability of isolated visceral sheep peritoneum
(2007)The permeability for small solutes and the ultrafiltration capacity of the peritoneum are essential for effective peritoneal dialysis (PD) treatment. Elucidation of the factors that regulate these two properties is therefore ... -
Fluid Penetration in a Deformable Permeable Web Moving Past a Stationary Rigid Solid Cylinder
(2017)We present an analysis for the process of fluid infiltration into a deformable, thin and permeable web that moves in close proximity over a rigid and stationary solid cylinder. While this is a process of significant interest ... -
Geomorphological analysis of Scopia catchment (Central Greece), using DEM data and GIS
(2015)In this study a geomorphological analysis of Scopia catchment was achieved, using digital elevation model (DEM) and GIS. The study area is a 7th order drainage catchment with total number and total length of streams 2, 303 ... -
Influence of the sodium transport inhibition by amiloride on the transmesothelial resistance of isolated visceral sheep peritoneum
(2005)The peritoneal mesothelium is a barrier to ion transport in peritoneal dialysis. In the present study, we used Ussing chamber experiments to investigate the effect of amiloride on the transmesothelial electrical resistance ... -
Inhibition by mercuric chloride of aquaporin-1 in the parietal sheep peritoneum: an electrophysiologic study
(2006)The peritoneal mesothelium is a barrier to ion transport in peritoneal dialysis. In this study, we used Ussing-chamber experiments to investigate the effect of HgCl2, an aquaporin-1 inhibitor, on the transmesothelial ... -
Matrix metalloproteinases 2 and 9 increase permeability of sheep pleura in vitro
(2012)Background: Matrix metalloproteinases (MMPs) 2 and 9 are two gelatinase members which have been found elevated in exudative pleural effusions. In endothelial cells these MMPs increase paracellular permeability via the ... -
mu-Opioid stimulation of isolated parietal sheep peritoneum decreases peritoneal permeability in vitro
(2007)The peritoneal mesothelium is one of the main barriers to ion transport in peritoneal dialysis. In a previous study, we showed the existence of a micro-opioid influence on the in vitro ionic permeability of serosal membranes ... -
New mutations in gidB gene associated with streptomycin resistance in Mycobacterium tuberculosis in Greece

A numerical model for aggregations formation and magnetic driving of spherical particles based on OpenFOAM®
(2017)Background and objective This work presents a numerical model for the formation of particle aggregations under the influence of a permanent constant magnetic field and their driving process under a gradient magnetic field, ... -
Pleural effusion osmolality correlation with pH and glucose level of pleural fluid and its effects on the pleural membrane permeability
(2021)Background and aim: Pleural effusions (PE) are a common clinical entity resulting from pathologies that affect the pleural space such as congestive heart failure, malignancy and pneumonia. The osmolality of the pleural ... -
Rapid effect of dexamethasone on the permeability of visceral sheep peritoneum
(2008)The peritoneal mesothelium is a biologic barrier to water and ion transport. Its functional and structural integrity is crucial for peritoneal dialysis treatment. In vivo studies have shown that corticosteroids increase ... -
Rapid effects of 17 beta-estradiol and progesterone on sheep visceral and parietal pleurae via a nitric oxide pathway
(2002)We investigated the effects of 17beta-estradiol and progesterone on transepithelial electrical resistance (R-TE) in sheep visceral and parietal pleurae. Specimens of intact pleurae from adult female sheep were used. The ... -
Sand fabric evolution effects on drain design for liquefaction mitigation
(2011)This paper revisits the seminal work of Seed and Booker (1977) [21] on the design of infinitely permeable drains for liquefaction mitigation. It is shown that their basic mathematical assumption for the rate of earthquake-induced ...
