White spot syndrome virus (WSSV) is a pathogen that causes high mortality in shrimp culture in the whole world. Sequence analysis of WSSV has shown similarity of WSSV isolates in different countries with exception of a few variable genomic loci. This study investigated the sequence variation of some Iranian WSSV isolates and previously identified isolates. Samples were collected during target ...

introduction oculocutaneous albinism (oca) is a genetically heterogeneous autosomal recessive genetic disorder that is characterized by reduced or completely absent pigmentation in the hair, skin, and eyes. conclusions a novel homozygous mutation, the deletion of exons 1 - 5 on the tyr gene, was found on the molecular genetic testing of this patient. exon 1 - 5 deletion on tyr causes a lack of ...

background:confirmation of olive oil authenticity and particularly virgin olive oil has a great importance. several advanced chemical and genetic analyses have been used to monitor especial components; however each has its limitations especially when detecting hazelnut-adulterated olive oil. objectives:the objective of this research is to assess the presence of trace amount of hazelnut oil in o...

background: sarcocystosis in south american camelids (sac) is an important parasitic disease which results in economical loss due to carcass condemnation. meat products from camelids are significant source of animal protein in several american countries. sarcocystis spp. producing macroscopical cysts in these animals have been nominated as s. aucheniae, s. tilopodi, and s. guanicoecanis. the ai...

heredity hearing loss (hl) is the most prevalent sensory disorder and most cases are non-syndromic. eighty percent of non-syndromic sensorineural deaf patients show an autosomal recessive pattern of inheritance. to date, 47 genes and 98 loci have been reported for this mode of inheritance. previous studies in our center showed the high prevalence of dfnb3 among iranian deaf families. pjvk (dfnb...

this paper investigates learner-initiated responses to english language teachers’ referential questions and learner initiatives after teachers’ feedback moves in meaning-focused question-answer sequences to analyze how interactional practices of language teachers, their initiation and feedback moves, facilitate learner initiatives. classroom discourse research has largely neglected learner init...

materials and methods an oligogearray® (an oligonucleotide-based gene expression array platform) containing 126 wnt signaling pathway-related genes was used to compare gene expressions between primary hcc and adjacent non-tumorous liver tissues from 10 patients with hcc. selected differential genes were identified with real-time rt-pcr and immunohistochemistry (ihc). in particular, the protein ...
