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 histamine on the electrophysiology of the human parietal pleura
(2011)Introduction: Histamine is involved in the pathogenesis of numerous diseases and regulates the permeability of different tissues. The aim of this study is to investigate the effects of histamine on the electrophysiology ... -
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: ... -
Enhancement of the transmesothelial resistance of the parietal sheep peritoneum by epinephrine in vitro: Ussing-type chamber experiments
(2005)The peritoneal mesothelium constitutes an ion transport barrier that is taken advantage of in peritoneal dialysis. The aim of this study was to investigate the effects of epinephrine on the electrical transmesothelial ... -
Human parietal pleura present electrophysiology variations according to location in pleural cavity
(2008)The aim of the study was to investigate if human pleura from different anatomical locations presents electrophysiology differences. Specimens were stripped over the 2nd-5th rib (cranial), 8th-10th rib (caudal), and mediastinum ... -
IGF-1 alters the human parietal pleural electrochemical profile by inhibiting ion trans-cellular transportation after interaction with its receptor
(2013)Objective: The effect of IGF-1 in the human pleural permeability and the underlying mechanisms involved were investigated. Design: Specimens from thoracic surgical patients were mounted in Ussing chambers. Solutions ... -

(2013)The crystal, electrical and electrochemical properties of the new composite materials of (1-x)SrTi0.5Fe0.5O3-δ-xCe0.8(Sm0.8Sr0.2)0.2O2-δ (0≤x≤1, Δx= 0.25) prepared by solid phase method. Composites have no phase interaction. ... -
Nonsteroidal Anti-Inflammatory Drugs Alter the Human Mesothelial Pleural Permeability via Ion Cellular Transportation by Inhibiting Prostaglandin Synthesis
(2012)Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) are used in clinical practice as analgesics or anti-inflammatory drugs. Studies have implicated them in participating in permeability throughout various tissues ... -
Permeability Alterations after Surgical Trauma in Normal Rabbit Peritoneum
(2010)Background: To investigate whether surgical trauma in a rabbit adhesion formation model and the administration of normal saline (N/S), icodextrin (ID) and/or dimetindene maleate (DM) changes the permeability of the normal ... -
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 ... -
Pleural electrophysiology alterations in spontaneous pneumothorax patients
(2010)Physiology changes of the pleura in spontaneous pneumothorax (SP) patients are not known with its etiology remaining unclear. The aim of the study was to investigate the pleural electrophysiology profile of SP patients and ... -
Pleural electrophysiology variations according to location in pleural cavity
(2009)The aim of the study was to compare the electrophysiology profile of sheep pleura originated from different locations of the pleural cavity with the respective profile in humans. Sheep specimens obtained from upper and ... -
Rapid effects of 17β-estradiol and progesterone on sheep visceral and parietal pleurae via a nitric oxide pathway
(2002)We investigated the effects of 17β-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 samples ... -
