Clinical pathology testing of rodents is often challenging due to insufficient sample volume. One solution in clinical veterinary and exploratory research environments is dilution of samples prior to analysis. However, published information on the impact of preanalytical sample dilution on rodent biochemical data is incomplete. The objective of this study was to evaluate the effects of preanaly...

Background and purpose: Medicinal plants are of great value in disease prevention and sustaining healthy communities. Marjoram is a plant of the mint family with large antibacterial effect on some microorganisms. Materials and methods: In this research the antimicrobial activity of marjoram alcoholic extracts (methanol and ethanol) were examined on Staphylococcus aureus (ATCC 25923), E.coli (A...

The aim of this work is to investigate the effect exhaust gas recirculation (EGR: water vapor and CO2), with without O2 enrichment, on non-premixed turbulent flames stabilized a swirl burner. motivation includes CO2 capture applications using CO2, combustion biogas that containing use EGR or H2O in certain industrial reduce pollutant emissions. Experiments were carried out coaxial burner placed...

Background and purpose: Mannoprotein in the cell wall of Saccharomyces cerevisiae is a glycoprotein with antimicrobial and antitoxin effects. In this research antifungal properties of gelatin based edible coating containing Saccharomyces cerevisiae mannoprotein were tested against Aspergillus flavus growth and the inhibitory effect on pistachio kernel. Materials and methods: Antifungal prope...

In the present study, we have reported the biological synthesis of silver nanoparticles (AgNPs) using aqueous leaf extract prepared by hot percolation treatment of wheat varities (PBW343, Triticum durum and Aegilops tauschii )for the reduction of silver ions to silver nanoparticles. Bioreduction of Ag+ to Ag0 was observed when aqueous extract augmented with silver nitrate (AgNO3) was incubated ...
