the application of a comprehensive model of communicative language ability (cla) to language teaching and testing has always been an imperative in l2 education since hymess proposal of communicative competence in the 1970s. recent l2 research has clearly underscored the importance of sufficient pragmatics representation as an essential component of cla in pedagogical and testing practices in l2...
abstract the present study was conducted to examine the effect of proficiency on students interaction while carrying out the grammar-based task(s) in collaboration. in particular, the study examines whether the level of proficiency affects the learners’ focus of attention to grammatical and lexical features. the study takes a further step and examines whether there is any difference in the use...
As many malaria-endemic countries move towards elimination of Plasmodium falciparum, the most virulent human malaria parasite, effective tools for monitoring malaria epidemiology are urgent priorities. P. falciparum population genetic approaches offer promising tools for understanding transmission and spread of the disease, but a high prevalence of multi-clone or polygenomic infections can rend...
CSN1S1is one of the major genes encoding milk proteins of mammals. In this study we determined allele frequencies of CSN1S1-5` flanking region as well as exon 17 variants and their effects on milk traits in three indigenous cattle breeds Mazandarani, Golpaygani (Bos indicus) and Sarabi (Bos taurus) and Holstein cattle in Iran. CSN1S1*B variant was nearly fixed in Holstein but ranged from 0.40 t...
background: atp-binding cassette transporter a1 (abca1) is a membrane integral protein which plays a vital role in high density lipoprotein (hdl) metabolism and exerts a protective effect against hypoalphalipoproteinemia (ha) by mediation of rate-limiting step in hdl biogenesis. in addition, this protein possesses anti-inflammatory effects by inhibiting the production of some inflammatory cytok...
Background and Objective: CCR5 is known as a main co-receptor in HIV infection. Many studies demonstrated that 32bp deletion in both CCR5 alleles provide natural resistance to HIV infection, so new treatment approaches are based on inducing this resistance by means of gene and cell therapies. This projects aim was the discovery of suitable candidates for new therapeutic strategies in addition t...
introduction the exposure of human beings to ionizing radiation from natural sources is a continuing and inescapable feature of life on earth. for most individuals, this exposure exceeds that from all man-made sources combined. materials and methods in this study, the annual effective dose in high level environmental background radiation areas (hlebras) of northern city of ramsar in iran was de...
The results showed that the Holstein BTN1A1gene has two alleles (A allele ) which is superior to second (B )in values of substitution effect and average allele, homo genotype AA over hetero AB was successful in breeding value traits. It also revealed through new equations gene responsible for characteristic milk production total output amount 37725 Iraqi dinars full price, it affects by ±7.24 d...
Background and purpose: This study aimed at examining the interaction between macronutrients, some micronutrients (magnesium, zinc, iron, calcium, and copper) and CCND2 rs11063069, ZNT8 rs13266634, and MC4R rs12970134 polymorphisms in relation to metabolic syndrome (MetS) and its components. Materials and methods: In this matched nested case-control study, the data for 1634 (817 pairs) case (t...
