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 ...

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...
