Ma, Thomas Y., Gary K. Iwamoto, Neil T. Hoa, Vimesh Akotia, Ali Pedram, Michel A. Boivin, and Hamid M. Said. TNFinduced increase in intestinal epithelial tight junction permeability requires NFB activation. Am J Physiol Gastrointest Liver Physiol 286: G367–G376, 2004; 10.1152/ajpgi.00173.2003.—Crohn’s disease (CD) patients have an abnormal increase in intestinal epithelial permeability. The def...
Unbound aggregates are the most common type of materials used for construction of the base layer of flexible pavements in Iran and worldwide. Due to the lack of binder, the performance of the compacted unbound aggregates is highly dependent on the properties of the gravel (particles remaining on sieve 4.75mm, sand (particles passing sieve 4.75mm and remaining on sieve 0....
AIM Maintenance of the blood and extracellular volume requires tight control of endothelial macromolecule permeability, which is regulated by cAMP signalling. This study probes the role of the cAMP mediators rap guanine nucleotide exchange factor 3 and 4 (Epac1 and Epac2) for in vivo control of microvascular macromolecule permeability under basal conditions. METHODS Epac1-/- and Epac2-/- C57B...
The impact of permeability on solute transport process in a highly heterogeneous aquifer was analyzed using the Monte-Carlo method. The logarithm of the permeability (lnK) of aquifer was considered as a non-stationary field with increments being a truncated fractional Lévy motion (fLm) generated using the SRA3DC code. MODFLOW and MT3DMS code were used to solve the flow and solute equations, res...
Intradermal injection of zymosan into nonsensitized rabbits induces plasma exudation, which is dependent on two mediators: C5a generated in extravascular tissue fluid and a vasodilator prostaglandin generated from substrates localized in cell membranes. This relationship between the complement system and the prostaglandin synthesis system had not previously been explored, and complement activat...
A critical event in ischemia-based cell death is the opening of the mitochondrial permeability transition pore (MPTP). However, the molecular identity of the components of the MPTP remains unknown. Here, we determined that the Bcl-2 family members Bax and Bak, which are central regulators of apoptotic cell death, are also required for mitochondrial pore-dependent necrotic cell death by facilita...
Investigating the biomechanics of cartilage could help to understand unique load-bearing property and optimize scaffold design in tissue-engineering. It is important model as a highly inhomogeneous fibril-reinforced biphasic material represent its complex composition structure. The depth-dependent strain-dependent properties would also play an role mechanical behaviour. However, differences rep...
The present investigation summarizes the effect of Linum usitatissimum fixed oil against different phases of acute inflammatory reaction, namely, protein exudation, peritoneal capillary permeability, and leukocyte migration. The fixed oil exhibited dose-dependent inhibition of protein exudation vascular permeability, comparable to standard aspirin. The oil also inhibited the leukocyte migration...
A series of Li-Cd ferrite samples of composition Li0.5-x/2CdxBi0.02Fe2.48-x/2O4 for x = 0.0 to 0.7 were prepared by conventional double sintering ceramic technique. From temperature dependent permeability, μ′ at T=TC indicates that the samples have high homogeneity according to Globus et al. The Curie temperature, TC is found to decrease with increasing Cd content. The sample with x=0.7 shows a...
