conclusions in this study, high prevalence of 91.7% hcmv gb1 genotype was predominant among hcmv-positive uc patients, which suggests that there might be an association between hcmv gb genotype 1 and uc disease. results among 98 patients with uc, only 12 (12.2%) patients were positive for hcmv genome, while the hcmv genome was not detected in any of the controls. (p = 0.002). the distribution o...

background : this comprehensive study was conducted on multi-purpose one-humped camel ( camelus dromedarius ) sera and ticks to assess the epidemiological aspects of the crimean-congo hemorrhagic fever virus (cchfv) in northeast iran. methods : from may 2012 to january 2013, eleven cities were randomly selected in the khorasan provinces of iran as “clusters,” and at least 14 one-humped camels w...

the nutrients are able to interact with molecular mechanisms and modulate the physiological functions in the body. the nutri­tional genomics focuses on the interaction between bioactive food components and the genome, which includes nutrigenet­ics and nutrigenomics. the influence of nutrients on f genes expression is called nutrigenomics, while the heterogene­ous response of gene variants to nu...

leishmania is a protozoan parasite belonging to the family trypanosomatidae, which is found among 88 different countries. the parasite lives as an amastigote in vertebrate macro­phages and as a promastigote in the digestive tract of sand fly. it can be cultured in the laboratory us­ing appropriate culture media. although the sexual cycle of leishmania has not been observed during the promastigo...

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...

background: gossypium thurberi is a wild diploid species that has been used to improve cultivated allotetraploid cotton. g. thurberi belongs to d genome, which is an important wild bio-source for the cotton breeding and genetic research. to a certain degree, chloroplast dna sequence information are a versatile tool for species identification and phylogenetic implications in plants. different ch...

The study of the demographic and adaptive history Homo sapiens has entered its golden age with advent genome-wide approaches. analyses genome diversity across different human populations have allowed us to better understand ways in which our species rapidly dispersed around world, how ancestors admixed archaic, now-extinct hominins, effects natural selection on genome. This work has, turn, made...

dna sequence determination is a tremendous human achievement. dna sequencing includes several methods and technologies in use for determining the order of the nucleotide bases (adenine, guanine, cytosine, and thymine) in a molecule of dna. knowledge of dna sequences has become indispensable for basic biological research, other research branches utilizing dna sequencing, and in numerous applied ...
