background: apical membrane antigen 1 (ama-1) is positioned on the surface of merozoite and it may play a role in attack to red blood cells. the mainaim of present study was to determine the genetic variation, as well as, to detect of selection at domain i of ama-1 gene plasmodium vivax isolates in iran. methods: blood samples were collected from 58 patients positive for p. vivax ,mono infectio...
background: meict is the first chlorotoxin-like peptide isolated from the iranian scorpion mesobuthus eupeus. chlorotoxin (ctx) is a neurotoxin that specially binds to (mmp-2) on ma-lignant cells and now is used in treatment of glioma. in the present study, we have used homology modeling to propose the 3d structure of meictand analyze its interaction with mmp-2 and its snp types. methods:the st...
conclusions these results show that zen and α-zol enhance the rate of cell division in er positive cells and therefore, exposure to this mycotoxin may increase the risk of breast cancer. results the results obtained from the present study demonstrated that both zen and α-zol enhance the cell viability of mcf-7 especially at low doses (1 - 500 ng/ml) and at a high dose of 125µg/ml after 24 and 4...
background: spermatogonial stem cells (sscs), a subset of undifferentiated type a spermatogonia, are the foundation of complex process of spermatogenesis and could be propagated in vitro culture conditions for long time for germ cell transplantation and fertility preservation. objective: the aim of this study was in vitro propagation of human spermatogonial stem cells (sscs) and improvement of ...
several modalities of drug administration have been investigated to improve bioavailability and to reduce 5-fu related toxicity. the aim of present study was to evaluate the effect of skimmed milk on the absorption and metabolism of 5-fu in rabbits, mice and dogs. it was further aimed to determine its route related toxicity in rabbits. plasma concentration of both 5-fu and its metabolite 5-f...
in this study, the densities, excess molar volumes and partial molar volumes of four binary systems containing n,n-dimethyl acetamide (dmac) with 1-alkanols (1-butanol up to 1-heptanol) are measured at 298.15 k. the results showed both constructive and expansive excess volumetric behavior for studying binary mixtures. deviation values of heavy alcohol have more positive and less negative excess...
conclusions our findings showed a high occurrence of metallo-β-lactamase production among p. aeruginosa isolates in burn patient infections in our region. also, there are p. aeruginosa isolates carrying the bla-vim-1 and bla-vim-2 genes in isfahan province. background metallo-β-lactamase-production among gram-negative bacteria, including pseudomonas aeruginosa, has become a challenge for treatm...
experimental autoimmune encephalomyelitis (eae) is a mouse model for multiple sclerosis (ms), this autoimmune disease is mainly mediated by adaptive and innate immune responses that lead to an inflammatory demyelination and axonal damage. imatinib mesylate is a selective protein tyrosine kinase inhibitor with immunomodulatory properties that abrogates multiple signal transduction p...
objective(s):blactx-mand blaper are two genes that encode class a extended-spectrum β-lactamases (esbls) and can be responsible for therapeutic problems. this study was carried out to evaluate the molecular properties of these genes in clinical isolates of enterobacteriaceae by polymerase chain reaction (pcr), restriction digestion and sequencing. materials and methods: during six months, start...
background and objectives : carbapenem resistant pseudomonas aeruginosa is a serious cause of nosocomial infections.the main purpose of the study is to determine the prevalence rate of imipenem resistant pseudomonas aeruginosa carrying metallo- beta- lactamase (mbl) genes. material and methods : 236 pseudomonas aeruginosa isolates were collected from teaching hospitals of ahvaz university of me...
