the aims of this study were to compare the promoter sequence of the mannose-binding lectin (cmbl) gene in iranian native and commercial chicken strains; as well as to compare the cmbl gene expression in crossbred and inbred chickens. in total 79 native (western azerbaijan native fowls, wanf) and 49 commercial (arian commercial strain, acs) birds were reared as parents under same management prac...

Three Iranian native strains and three Japanese commercial lines of the silkworm Bombyx mori were analyzed using amplified fragment length polymorphism (AFLP) markers. A set of ten PstI/TaqI primer combinations amplified a total of 322 bands out of which 251 (%78) were polymorphic. Estimates of Nei’s gene diversity for all loci in individual strains and commercial lines indicated a higher degre...

This study investigated whether Iranian EFL learners are aware of different varieties of English spoken throughout the world and whether they have tendency towards a particular variety of English. Likewise, it explored the attitudes of Iranian EFL learners towards the native and non-native varieties of English. Moreover, it made an attempt to investigate whether such attitudes are gender-orient...

The polyadenylation of Fowl Plague Viral RNA and of Influenza A/Victoria Viral RNA using E. coli poly (A) polymerase and the subsequent reverse transcription of the polyadenylated species is reported. We have shown that all 8 genome fragments are adenylated and that an average of 25--30 adenylic acid residues per molecule is sufficient for maximal transcription with reverse transcriptase. The c...

infectious bronchitis virus (ibv) is a contagious pathogen in fowl that results in economic loss in the poultry industry. in this study, the amino acids sequences of three structural proteins m, n, and s1 for five iranian ibv isolated during 1998-2011 have been analyzed. conserved and variable regions, hydrophobic characteristics and identity matrix were determined after alignment by bioedit ve...

Here, we studied the genetic diversity of native fowls in Laos by analyzing a mitochondrial DNA (mtDNA) sequence polymorphism. A 546-bp fragment of the mtDNA D-loop region was sequenced in 129 chickens from the areas of Vientiane, Luang Prabang and Pakse. In total, 29 haplotypes were identified and formed five clades. Haplotype diversity and nucleotide diversity of the native fowls in Laos were...

Fowl show spontaneous elevation of blood pressure and neointimal plaque formation in the abdominal aorta at young ages. A similar neointima can be induced by a balloon-catheter-induced endothelium injury to the fowl aorta. Both spontaneously developed and injury-induced vascular lesions exhibit subendothelial hyperplasia consisting of neointimal cells with a synthetic phenotype and abundant ext...

BACKGROUND As English has increasingly become the lingua franca in science and international journals require native-like academic writing standards from nonnative researchers, there is more pressure on nonnative scholars to write their research articles more accurately and appropriately in English. This study was conducted to determine the most-occurring language-related errors which Iranian m...

A case of human fowl plague keratoconjunctivitis occurred after accidental laboratory exposure. The conjunctivitis was characterised by follicle formation and a mucopurulent discharge, and ran a self-limiting course over two weeks. The keratitis was of an unusual type and consisted of small intraepithelial opacities, which appeared after one week and resolved completely over the next three week...
