background: resistant strains of pseudomonas aeruginosa to imipenem was medical treatment problem, especiallyin burnt units of hospitals. objectives: this study was conducted to evaluate the antimicrobial effect of fe2o3 nanoparticles alone and functionalized with imipenem on p. aeruginosa starins producing metallo b-lactamases (mbl).materials and methods: a disk diffusion method was used to is...

background transfusion-induced iron overload leads to many complications in patients with β-thalassemia major. this study aimed to compare the level of iron stored in the liver and heart measured by mri t2 * with ferritin levels in these patients. materials and methods this study was done on 52 patients with β-thalassemia major aged 7 to 29 years. serum ferritin level was checked and heart and ...

background: thalassemia syndromes are the most prevalent single gene disorders in iran. this study aimed to evaluate the effect of different types of beta-globin gene mutations, co-inheritance of alpha-globin gene mutations and/or xmn1 snp on disease phenotype in a large cohort of iranian patients. subjects and methods: in total, 433 patients were clinically classified into β-thalassemia major ...

background: the canonical wnt signal transduction (or the wnt/β-catenin pathway) plays a crucial role in the development of animals and in carcinogenesis. beta-catenin is the central component of this signaling pathway. the activation of wnt/β-catenin signaling results in the cytoplasmic and nuclear accumulation of β-catenin. in the nucleus, β-catenin interacts with the tcf/lef transcription fa...

The chemical composition of plant polyphenols Plantago major L. and lanceolata growing in Uzbekistan was studied. More than 20 compounds, including 7 flavonoids, 9 phenolic acids, 8 hydrolysable tannins, the ages which have been determined using physicochemical methods research isolated from plants. From P. L., along with well-known such as gallic acid, rutin, luteolin, isorhamnetin, hyperoside...

background extended-spectrum β-lactamase (esbl) production is the major resistance mechanism to β-lactam antibiotics in enterobacteriaceae. in addition, emergence of plasmid-mediated quinolone resistance (pmqr) in esbl-producing isolates has become a global threat for treatment of these infections. objectives we investigated the association between esbl production and quinolone resistance in ur...
