objective: toxoplasmosis may cause significant damage to the developing fetus and is a life-threatening opportunistic infection in immunocompromised persons. molecular methods are known to be more sensitive and more specific than serological assays for diagnosis of toxoplasmosis. application of quantitative pcr has evolved sensitive, specific, and rapid method for the detection of rh strain of ...

direct agglutination test (dat) is a sensitive and simple method, which is applicable in field and unequipped laboratories. in order to evaluate dat in the diagnosis of toxoplasma infections, the antigen was prepared in the protozoology unit, school of public health and it was used in the following studies. a- 251 serum samples collected from suspected toxoplasmosis out-patients were examined f...

one of the most important aspects of software project management is the estimation of cost and time required for running information system. therefore, software managers try to carry estimation based on behavior, properties, and project restrictions. software cost estimation refers to the process of development requirement prediction of software system. various kinds of effort estimation patter...

a rapid and sensitive reverse transcription polymerase chain reaction (rt-pcr) and nested-pcr were used to detect bovine viral diarrhea virus 1 (bvdv-1) in bull semen. selected primers could amplify a part of the 5´utr of the bvdv genome. a 294 bp dna fragment was amplified and specificity of the results was confirmed by direct sequencing of the pcr product. prior to rna extraction, the seminal...

objectives: toxoplasma gondii is a coccidian protozoon which forms tissue cyst in different organs of infected intermediate host. the present study was conducted to demonstrate the active form of parasite in different tissues of rat, which was experimentally infected with rh strain of toxoplasma gondii using bioassay method inmice. materials & methods: in the experimental assay, 75 rats an...

in this study, performance of oil droplet separator in crankcase ventilation system for three engines, ford-ecoboost (impactor with variable area), nissan-vq37de (inertial impactor), and peugeot-xu7 (cyclone) at the same volumetric flow rate has been studied experimentally. because of the complexities of geometrical and functional in internal combustion engines, a test rig is designed to study ...

concrete filled steel tube columns (cfst) are a kind of composite columns according to advantages of cfst relative to reinforced concrete and steel columns. use of these materials is common in recent years especially in high building, unnecessary of molding, high ductility, proportionate resistance with low volume, economical, low deformation relative to steel columns are among advantages. in t...
