In this study, antifungal property of olive leaf extracts against Candida albicans PTCC-5027 was examined. Fresh olive leaf extracts were prepared using distilled water in a Soxhlet apparatus. The antifungal activity of the extract was analyzed by measuring the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC), using the microdilution test and disc diffusion assa...
the present study was conducted to investigate the role of summary in teaching grammar process on pre-university students. to this end, 48 male pre-university students in semnan were participants. they were math class that we called experimental group and science class as control group. in order to make sure there was no significant difference in proficiency level of two groups. a pre-test wa...
i ntroduction: calcium hydroxide (ch) is one of the most common intracanal medications. corticosteroids (cs) are used in endodontics because of their anti-inflammatory activity. this study aimed to evaluate the antimicrobial effect of ch+betamethasone and ch+saline against enterococcus faecalis ( e. faecalis ) using agar diffusion test and measuring the microbial zone of inhibition (zoi). metho...
BACKGROUND There is wide spread interest in drugs derived from plants as green medicine is believed to be safe and dependable, compared with costly synthetic drugs that have adverse effects. METHODS We have attempted to evaluate the antioxidant, In vitro thrombolytic, antibacterial, antifungal and cytotoxic effects of Clausena heptaphylla (Rutaceae) stem bark extract ethanol extract. RESULT...
this paper reports on preparation of polyamide membrane with addition of silver nanoparticles (agnps). agnps act as antibacterial agents that are less susceptible to membrane’s biofouling by interfacial polymerization (ip) method. agnps was synthesized via green route which has been reported previously. attenuated total reflectance-fourier transform infrared spectroscopy (atr-ftir), field emiss...
Teh-tehan (Acalypha siamensis) is a plant that has many branches including bush with height of 1-2 m. Escherichia coli bacteria can be found in the human intestine, most these are harmless, but some cause serious poisoning humans such as diarrhea. The purpose this study was to determine antibacterial activity ethanol extract tea-tea leaves against using disc method. This research descriptive by...
INTRODUCTION The purpose of this study was to investigate the antibacterial effect of 71 locally produced honeys from different botanical sources collected from apiarist's open markets in Sicily. METHODS Antimicrobial activity was determined against Escherichia coli (ATCC 25922) and Salmonella serovar Infantis (ATCC 1523) by an agar-diffusion assay from the estimation of the diameter of the i...
Comparative efficacy of antimicrobial agents used in endodontic treatment on selected microorganisms
This study was undertaken to compare and evaluate the antimicrobial efficacy of Biopure MTAD a root canal irrigant used for final rinse and commonly used intracanal medicament Metapex against Enterococcus faecalis and Propionibacterium acne .Agar disc diffusion test was done to compare and evaluate antimicrobial efficacy of Biopure MTAD (Dentsply Tulsa Dental, Tulsa, OK) and Metapex (META BIOME...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
with the growth of more humanistic approaches towards teaching foreign languages, more emphasis has been put on learners’ feelings, emotions and individual differences. one of the issues in teaching and learning english as a foreign language is demotivation. the purpose of this study was to investigate the relationship between the components of language learning strategies, optimism, duration o...
