Aims: The aim of this study was to evaluate the antifungal effect adding nanoparticles with different concentrations into irreversible hydrocolloid impression materials. Materials and Methods: This evaluated MgO ZrO2 by Minimum inhibitory concentration (MIC) minimum fungicidal (MFC) using Agar-Well diffusion method after incorporation material. Results: results showed that MIC MFC magnesium oxi...

Background and Aim: In recent years, due to the indiscriminate and irrational use of synthetic drugs, the resistance of pathogenic microorganisms has increased; therefore, new compounds are vitally needed. The purpose of this study was to investigate the effect of ethanolic and aqueous extracts of Berberis vulgaris on Escherichia coli, Klebsiella pneumoniae, Proteu...

Chinese hamster ovary (CHO) cells are considered as the most commonly used host for industrial manufacturing of therapeutic proteins. The aim of this study was to evaluate the minimum inhibitory concentration (MIC) of hygromycin B in both CHO-DG44 and CHO-S cells since hygromycin B resistance cassette can be used for future selection of gene expression in CHO cells. The minimum inhibitory conce...

Clavulanic acid, a potent beta-lactamase inhibitor, reduced the minimum inhibitory concentrations of carbenicillin for 13 of 15 clinical isolates of Serratia marcescens by at least eightfold. The combination of clavulanic acid and carbenicillin also exhibited synergistic activity with gentamicin against 11 of 15 isolates tested, including 9 of 10 strains which were highly resistant to carbenici...

Natural compounds including essential oils (EOs) are used to inhibit the pathogenic bacterial growth in foods. The objective of this study was to investigate the combined effect of Trachyspermum ammi EO and propolis ethanolic extract (PEE) on some food pathogenic bacteria. In this study, the effect of T. ammi EO and PEE at different concentrations, individually and in combinat...

the genus teucrium (germander) belongs to the family lamiaceae, within the subfamily ajugoideae .teucrium polium l. (labiatae) has long been recognized in folk medicine in the treatment of many pathophysiological implications, such as gastrointestinal disorders, inflammations, diabetes and rheumatism. in this study antimicrobial activity of two crude extracts obtained from teucrium polium l. wa...
