In this study, Invitro evaluation of some Iranian plants against Staphylococcus aureus Isolation of Urinary Tract Infection by microtiterplate method. All 12 strains of Staphylococcus aureus isolated from urine culture of hospitalized patients during the years 2012- 2013. Minimum Inhibitory Concentration (MIC) of plant extract and essential oilagainst bacteria were determined ...
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...
Different solvent extracts of a red algae, Hypnea flagelliformis,and two brown algae, Cystoseira myrica and Sargassum boveanum, collected from the Persian Gulf coast were subjected to different bioassays including: 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging assay, antibacterial and antifungal activity by thin layer chromatography (TLC)-bioautography, agar disc diffusion (ADD) ...
Background: Cefepime was used as empirical treatment in ventilator-associated pneumonia (VAP) induced by gram-negative and gram-positive bacteria. This study aimed to determine the antimicrobial susceptibility pattern of cefepime against microorganism causing VAP in Mazandaran, North of Iran. Methods: This study was performed on VAP patients diagnosed with clinical pulmonary infection score (CP...
Quantitative predictions for the spread of mutations in bacterial populations are essential to interpret evolution experiments and to improve the stability of synthetic gene circuits. We derive analytical expressions for the suppression factor for beneficial mutations in populations that undergo periodic dilutions, covering arbitrary population sizes, dilution factors, and growth advantages in ...
Pasture micro-nutrient concentrations are often deficient for herbage productivity and the health of livestock. The aim this study was to investigate soil content effects on yield three pasture systems North Wyke Farm Platform (NWFP): high-sugar grass + legume mix minus nitrogen (N) fertilizer (blue/HSG L); permanent plus N (green/P N); (red/HSG N). locations with high total had a greater slope...
This paper reports on the state-of-the-art of technologies for the design and fabrication of MEMS micro-mirrors. We discuss the major design issues, considerations, calculations and restrictions of micro mirrors. The materials employed for the reflective surfaces are described along with their properties. The materials used for the static and dynamic MEMS micro structures as well as the differe...
Background and Objective: Saccharomyces cerevisiae is one of the probiotic yeasts that has positive effects on health. Pseudomonas aeruginosa is one of the important opportunistic pathogenic bacteria. The purpose of this study was to determine the effect of supernatant of Saccharomyces cerevisiae on preventing the growth of Pseudomonas aeruginosa and its effect on exotoxin S gene expression by ...
