the staphylococci are important pathogenic bacteria causing various infections in animals and human. hemolysin is one of the virulence factors of coagulase-positive (cps) and coagulase-negative staphylococci (cns). the aims of the study were to characterize hemolysins of staphylococcus spp. isolated from human and bovine origin, phenotypic- and genotypically. characterization of hemolysin pheno...

background: lactoferrin (lf) is a glycoprotein, a member of the transferrin family.from ten known mechanisms of anti-cancer chemoperotecive compounds, lf alone, has six of these functions and inhibits cancer. in this study, the effect of lactoferrin purified from bovine colostrum was studied as an anti-cancer agent on esophageal cancer cell line. materials and methods: bovine colostrum were col...

in this study, we performed a bacteriological investigation on bovine respiratory infections. additionally, the study evaluates the efficacy of florfenicol 30 µg produced by rooyan darou company (test group) as compared to a similar drug produced by aboraihan company (control group). sampling was carried out on 30 calves at two farms with 30-55% incidence rate of respiratory disorders. nasophar...

introduction : deproteinized bovine bone mineral (bio-oss) is a xenogenic bone substitute, widely used in maxillofacial bone regeneration. the aim of this in vitro study was to investigate its influence on the growth behavior of human osteosarcoma cell line, saos-2 culture, and compare it with the physiologic dose of dexamethasone, an inductive factor for osteoblasts. materials and methods: hum...

background: fetal dna in maternal plasma and serum has been shown to be a useful material for prenatal fetal sex determination during early gestational ages. non-invasive prenatal diagnosis is now possible at 8th week of pregnancy, by maternal blood sample testing. objective: the purpose of this study was to evaluate two dna extraction methods from mother plasma and its routine clinical applica...

Magnetic polymer particles which were modified by vinyl groups and subjected topolymerization by vinyl β-Cyclodextrin derivative, has been used as adsorbent for sorption andrelease of bovine serum albumin and the equilibrium and kinetics of the adsorption process werestudied. The absorbability and releasing of this protein through the new polymer has beenmeasured by ultraviolet-visible spectros...

The pH dependence study reveals that the Cys 206 sulphydryl group of bovine carbonicanhydrase in the native form is not exposed. During the reaction of 2,2'-dithiobispyridine (2-DTP) with the enzyme, there was no absorbance change recorded. In the presence ofsurfactants, the pH dependence profiles of the apparent second order rate constants, kapp, forthe reaction of 2-DTP with bovine carbonic a...

Aegle marmelos and Murraya koenigii are the plants with impending medicinal properties. Both contain various phyto-constituents that could be utilized for treatment of ailments in human animal species. The A. M. easy to procure their use is cost-effective which makes them important particularly livestock health management. rich trace minerals antioxidants augment nutraceutical values. In additi...
