in this investigation aflatoxin contamination of eighty different iranian white cheeses were determined by t.l.c. method. the result of this study showed that, 97.5% of the samples contained aflatoxin m1 & m2 which are transferred from milk. as far as direct contamination, 30% of the samples contained aflatoxin b1, g1, g2, from which 2.5% contained aflatoxin b1, 5% contained aflatoxin b2, 20% c...
chitosan (chito) as a biopolymer with high antibacterial, biocompatibility and biodegradability and polyaniline (pani) as a conductive polymer and silver (ag) nanoparticles to enhance antibacterial property were used to prepare polyanilin-chitosan-silver (pani-chito-ag) nanocomposites. the synthesis of panichito composite and pani-chito-ag nanocomposite was performed through aniline polymerizat...
Green biosynthesis of silver - functionalized multiwalled carbon nanotube (Ag/FMWCNT) nanohybride from silver nitrate solution using water extract of Satureja hortensis L as reducing agent and FMWCNT as anchoring agent at room condition was succesfully carried out. Water-soluble organics present in the plant materials were mainly responsible for the reduction of silver ions to nano-sized Ag par...
OBJECTIVE To compare performance of contemporary aquaporin-4-immunoglobulin (Ig) G assays in clinical service. METHODS Sera from neurologic patients (4 groups) and controls were tested initially by service ELISA (recombinant human aquaporin-4, M1 isoform) and then by cell-based fluorescence assays: fixed (CBA, M1-aquaporin-4, observer-scored) and live (fluorescence-activated cell sorting [FAC...
Introduction: Aflatoxin M1 (AFM1) is a highly toxic compound which is stable during milk processing, and Storage. Hence, it may be found as contaminant in milk and dairy products with hazardous effects for human beings. In this regard, several studies have demonstrated the potential of process to remove Aflatoxin M1 from dairy product. Therefore, the aims of this study were to assess the abilit...
sulphosalts in the system agsbs2-agass2 have been experimentally investigated using dry methods. the solid solutions which form between ?-miargyrite and smithite have different structures. the epma data for the solid solution series show that there is an inverse relation between sb and as. the cell parameters of the solid solution between ?-miargyrite and smithite increase up to about 50% of...

The present paper describes the preparation and characterization of Polyvinyl Alcohol-Polypyrrole-Silver Nanocomposite (PVA-PPy-Ag NC) films. The prepared films were conducting, freestanding, flexible, and robust. Silver nanoparticles (Ag NPs) were synthesized from an aqueous solution of silver nitrate using trisodium citrate as a reductant. The casting solution for the films was prepared by in...
