Essential Oils Nanoemulsions: ‎Preparation, Characterization and Study of ‎Antibacterial Activity against Escherichia ‎Coli

   This research studies the application of essential oil nanoemulsion as herbal medicine instead of using antibiotics and chemicals. Thyme, shirazi thyme and rosemary essential oils were selected as herbal drugs. Essential oil nanoemulsions with Tween 80 and/or Sodium dodecyl sulfate (SDS) surfactants were prepared and investigated. Physicochemical characterizations such as hydrodynamic di...

exploring motivation and english test preparation strategies of iranian pre-university candidates during and at the end of test preparation period for konkur examination

the current study aimed at investigating the relationship between motivation and test preparation strategies (tpss) used by iranian pre-university students in their preparation period for the university entrance exam (uee). due to the importance of uee in iran, this study also attempted to show its impact on these two important variables. to this end, 100 pre-university students in an iranian p...

Preparation of procoligenoids from Escherichia coli heat-labile enterotoxins.

Heat-labile enterotoxins from Escherichia coli strains of porcine and human origin polymerize on heating to form high-molecular-weight aggregates, "procoligenoids," analogous to procholeragenoid derived from the cholera enterotoxin. This aggregation is accompanied by loss of biological activity (toxicity). Further heating results in the release of B-subunit oligomers, coligenoids, analogous to ...

The efficacy of an Escherichia coli-derived phytase preparation.

Five experiments were conducted to evaluate the effect of an Escherichia coli-derived phytase on phytate-P use and growth performance by young pigs. The first experiment involved time course, pH dependence, and phytase activity studies to investigate the in vitro release of P from corn, soybean meal, and an inorganic P-unsupplemented corn-soybean meal negative control diet. In Exp. 2, which was...
