Introduction: Aflatoxin M1 is an important mycotoxin frequently found in milk and dairy products. The main objective of this work was to study the stability of AFM1 during production and refrigerated storage of probiotic yogurt. Materials and methods: Two kinds of probiotic yogurt were made by cow’s milk artificially contaminated with aflatoxin M1 at a level of 100 ng/l, and fermented...

In atherosclerotic arteries, blood monocytes differentiate to macrophages in the presence of growth factors, such as macrophage colony-stimulation factor (M-CSF), and chemokines, such as platelet factor 4 (CXCL4). To compare the gene expression signature of CXCL4-induced macrophages with M-CSF-induced macrophages or macrophages polarized with IFN-gamma/LPS (M1) or IL-4 (M2), we cultured primary...

OBJECTIVES This study investigated the effect of porcelain firing on the misfit of implant-supported frameworks and analyzed the influence of preheat treatment on the dimensional alterations. MATERIALS AND METHODS Four external-hex cylindrical implants were placed in polyurethane block. Ten frameworks of screw-retained implant-supported prostheses were cast in Pd-Ag using 2 procedures: (1) co...

Background and Purpose :Aflatoxin M1, in milk and dairy products, is classified by the International Agency for Research on Cancer as human carcinogens (class 2B). The aim of this study was to evaluate aflatoxin M1 contamination level in dairy products from Iranshahr city, Iran, using ELISA technique. Materials and Methods: In our study, 87 samples of milk, white cheese, yoghurt, and butter...

Background and Aims: Virus-like particles (VLPs) have been suggested to be a promising recombinant vaccine approach. Several studies have reported that the influenza VLPs produced in insect cells is an effective vaccine candidate. Due to crucial role of matrix M1 protein in assembly and budding of Influenza particles, in all VLPs structures, M1 protein have been considered as a main component. ...

background: genetic polymorphisms of cytochrome p450 in humans are the main cause of differences in the metabolism. the allele and genotype frequencies of cyp2c19 and cyp2c9 have been studied in some iranian populations. the aim of present study was to examine the frequencies of cyp2c18m1, and cyp2c18m2, alleles in the mazandarani ethnic group among iranian population. materials and methods: in...

objective: in this study, two conserved genes (m1 and np) of influenza virus were expressed in a bicistronic vector in order to develop a universal gene based vaccine. materials and methods: plasmids m1-pires2-egfp, pires2-np were constructed by cloning the pcr products of m1 and np genes which were amplified from the a/peurto rico/8/34 (h1n1) influenza virus strain into the plasmid expression...
