Allergy to Prosopis juliflora (mesquite) pollen is one of the common causes of respiratory allergy in tropical countries. Mesquite is widely used as street trees in towns and ornamental shade trees in parks and gardens throughout arid and semiarid regions of Iran. The inhalation of mesquite pollen and several species of Amaranthus/Chenopodiaceae family is the most important cause of allergic re...

Extracellular matrix (ECM) turnover and remodeling are initiated, at least in part, by the regulated secretion of members of a family of matrix metalloproteinases. Human and bovine trabecular mesh-work in culture secrete interstitial collagenase, both the 72- and the 92-kD forms of type IV collagenase (gelatinases) and stromelysin, and the tissue inhibitor of metalloproteinases (TIMP). These pr...

Various amino acid-derived compounds, for example, Nα-Cocoyl-L-arginine ethyl ester (CAE), alkyloxyhydroxylpropylarginine, arginine cocoate, and cocoyl glycine potassium salt (Amilite), were examined for their virucidal activities against herpes simplex virus type 1 and 2 (HSV-1 and HSV-2), influenza A virus (IAV), and poliovirus type 1 (PV-1) in comparison to benzalkonium chloride (BKC) and so...

An enhanced electrokinetic process for removal of metals (Cr, Cu, Fe, Ni, Pb, Zn) from an industrial wastewater sludge was performed. The electrokinetic experiments were conducted under a constant potential gradient (1.25 V cm(-1)) with processing fluids of tap water (TW), sodium dodecylsulfate (SDS) and citric acid (CA) for 5 days. Results showed that metal removal efficiency of heavy metals f...

BACKGROUND The timely and accurate diagnosis of specific influenza virus strains is crucial to effective prophylaxis, vaccine preparation and early antiviral therapy. The detection of influenza A viruses is mainly accomplished using polymerase chain reaction (PCR) techniques or antibody-based assays. In conjugation with the immunoassay utilizing monoclonal antibody, mass spectrometry is an alte...

We tried to extract and purify bone morphogenetic protein (BMP) from bovine demineralized dentin matrix (DDM). Crude dentin BMP (d-BMP) was extracted from DDM in 3 sequential steps. Purification of crude d-BMP was carried out by liquid chromatography. The molecular weight and the isoelectric point of the purified d-BMP were determined by sodium dodecylsulfate polyacrylamide gel electrophoresis ...

Glycophorin A forms homodimers through interaction of the single, helical transmembrane domains of the monomers. The dimers are stable in sodium dodecylsulfate (SDS), permitting a number of studies that have identified a critical motif of residues that mediates dimer formation. We have used analytical ultracentrifugation to measure the energy of dimerization in a non-denaturing detergent soluti...

Thrombospondin is a large extracellular-matrix protein that is released by smooth muscle cells and platelets and is distributed widely in mammalian brain. By using western blotting with a monoclonal antibody against the calcium-binding domain of thrombospondin, the authors detected a 180-kD glycated polypeptide in the trabecular meshwork tissue of normal human and porcine eyes. The epitope-bear...

The oxygen scavenging of C-centered radicals in microheterogeneous media was studied by investigation of the photolysis of several ketones (dibenzyl ketone (DBK), oand p-methyldibenzyl ketone (o-MeDBK andp-MeDBK) and d,l-2,4-diphenyipentan-3-one (d,~-DPP)) in oxygen-saturated sodium dodecylsulfate (SDS) micellar solution. The acyland benzyl-type radicals initially formed during the photolysis o...
