lactoferrin (lf) is a bioactive protein present in all external secretions such as milk that plays important role in the innate host defense. therefore, the lf has a major role in bovine mammary gland defense during mastitis. in this study, 5’-flanking region of bovine lf gene containing three single nucleotide polymorphisms (snps) at positions −602 (t/g), −600 (a/g) and -586 (t/c) were screene...

three species belonging to three genera of the family tylenchidae, namely, cephalenchus leptus, eutylenchus excretorius, and lelenchus leptosoma were discovered as first reports for iran's nematode fauna. they were characterized by morphological, morphometric and molecular phylogenetic studies. the two latter genera are new for iran. iranian population of cephalenchus leptus is characterized by...

the melanocortin-1 receptor mc1r is encoded by the extension locus, playing a fundamental role in the determination of coat color in a number of mammalian species. however, so far there has been no report regarding the single nucleotide polymorphisms (snps) of the mc1r promoter region and the potential association of its snps with coat color in sheep (ovis aries). throughout the present study, ...

interleukin-1β (il-1β), the prototypical pro-inflammatory cytokine, is produced by macrophages following exposure to bacterial products. its role is to act upon several cell types at the site of infection to stimulate the production of pro-inflammatory molecules that will cause increase in vascular permeability. therefore, il-1β regulates the initiation and development of acute inflammation tha...

background south pars special economic energy zone is the world's second largest gas reservoir that was established two decades ago. high incidence of social harms is observed in this region due to various problems such as drug addiction which is of high prevalence. conclusions it is necessary to implement simultaneous national interventions as soon as possible to improve the economic, social, ...

background: the purpose of this study is to fabricate inexpensive in-house low cost homogeneous and heterogeneous human equivalent thorax phantom and assess the dose accuracy of the treatment planning systems (tps) calculated values for different lung treatment dosimetery. it is compared with thermoluminescent dosimeter (tld) measurement. materials and methods: homogeneous and heterogeneous tho...

a finite volume-lattice boltzmann algorithm is applied to study skin friction behaviour in different channel flows. for this purpose, cell centred scheme is adapted to discretize the boltzmann equation and consistent boundary conditions are also addressed, which resulted in a wider domain of stability. a simulation of flow in a two dimensional channels with different geometries are carried out....

we describe a case of leishmaniasis in a 55-year-old male who presented with weakness, fever and anemia. the patient was born and lived all his life in talaghan, a non-endemic region of kala-azar and there was no history of travel to endemic reigon for leishmania. in primary diagnosis, the patient suspect has been myelofibrosis and then lymphoma and underwent chemotherapy . his general conditio...

purpose : to offer a semi-automatic algorithm to determine the area of angiographic hyperfluorescence methods : the proposed algorithm included wavelet filter, histogram equalization and modified otsu thresholding. hyperfluorescent area of 30 angiographic images obtained from patients with leaking choroidal neovascularization (cnv) and diabetic retinopathy were evaluated and the results were co...

objective(s): helicobacter pylori, a human specific gastric pathogen is a causative agent of chronic active gastritis. the vacuolating cytotoxin (vaca) is an effective virulence factor involved in gastric injury. the aim of this study was to construct a recombinant protein containing antigenic region of vaca gene and determine its antigenicity.   materials and methods: the antigenic region of v...
