background: toxoplasmosis is one of the most important food-borne diseases distributed worldwide. in order to determinate the involvement of poultry meat in clinical toxoplasmosis, this study aimed to genetic characterization of toxoplasma gondii in tissue samples of serologically positive chickens of tunisia using polymerase chain reaction (pcr). methods: trail of isolation of local t. gondii ...

the olefins polymerization process in a slurry reactor is discussed. the reaction rate dynamics was analyzed and the contributions of feed flow, gas-liquid mass transfer, polymerization reaction, and catalyst deactivation were estimated. the propylene solubility in a solvent mixture “heptane” was calculated using soave-redlich-kwong equation of state. these data were then approximated by henry-...

background: cytochrome p450 2c19 (cyp2c19) is important in metabolism of wide range of drugs. cyp2c19*17 is a novel variant allele which increases gene transcription and therefore results in ultra-rapid metabolizer phenotype (urm). distribution of this variant allele has not been well studied worldwide. the aim of present study was to investigate allele and genotype frequencies of cyp2c19*17 in...
