abstract       background and objective: hepatitis b virus (hbv) is a dna virus with high tendency toward hepatic tissue. there are currently about 3 million hbv-infected people and 350 to 400 million chronic carriers of this virus in the world. x protein plays a role in the over-expression of oncogenes, carcinogenicity of liver cells and overlaps with the basal core promoter of the virus. muta...

The strongest evidence for host specificity of mammalian trypanosomes comes from parasites of the subgenus Trypanosoma (Herpetosoma). Laboratory studies have shown that T. (Herpetosoma) species will not infect an alternative host. However, this has not been demonstrated in wild populations. We screened 560 bank voles (Clethrionomys glareolus) and 148 wood mice (Apodemus sylvaticus) for trypanos...

Puumala (PUU) hantavirus is the aetiological agent of nephropathia epidemica (NE), a mild form of haemorrhagic fever with renal syndrome, which occurs in Fennoscandia, central Europe and Russia. In Norway, NE-like disease has been reported since 1946 and about 50 cases are diagnosed annually; however, the causative agent has not been characterized. In this study, a virus originating from bank v...

the purpose of present paper was to examine the relationship between central bank independence and inflation rate in iran over 1960-2008. first, central bank independence has been accomplished through three indices including legal and real cbi indices and turnover rate of central bank governor index. then, augmented dickey-fuller test for model stationary of variables has been done by applying ...

The rad4.116 mutant of the fission yeast Schizosaccharomyces pombe is temperature-sensitive for growth, as well as being sensitive to the killing actions of both ultraviolet light and ionizing radiation. We have cloned the rad4 gene by complementation of the temperature sensitive phenotype of the rad4.116 mutant with a S. pombe gene bank. The rad4 gene fully complemented the UV sensitivity of t...

Objective: Identity the genetic aspects and major gene influence on energy balance, milk production, fertility, food safety and consumer are the recent interests of genetic and breeding researchers. Methods: Najdi Cattle is the most prominent breeds in Khuzestan province. To do this plan in Shoushtar Najdi Cattle Station, blood samples were taken from 15 Najdi Cattles. DNA was extracted from wh...

objective: the role of staphylococcal enterotoxin b (seb) in food poisoning is well known, however its role in other diseases remains to be explored. the aim of this study is the molecular screening and characterization of the seb gene in clinically isolated strains. materials and methods: in this experimentally study, 300 staphylococcus aureus (s. aureus) strains isolated from clinical samples...
