INTRODUCTION The purpose of this in vitro study was to assess the antifungal activity of final canal rinse with either three concentrations of sodium hypochlorite (NaOCl) (0.5, 2.6 and 6%), two concentrations of chlorhexidine (CHX) (2% and 0.2%), MTAD, Tetraclean, Hypoclean and Chlor-Xtra on Candida albicans (C. albicans) in a human tooth model. METHODS AND MATERIALS Two hundred and thirty fi...
In the present study, we examined the effects of nano tantalum (Ta) dental implants on inducing osteoblast proliferation and differentiation. The MG-63 osteoblasts were divided into 3 groups after recovery, passage and storage: i) Osteoblast culturing group (control group); ii) osteoblast and titanium (Ti) implant co-culturing group (Ti group); and iii) osteoblast and Ta implant co-culturing gr...
In 2010, the World Bank categorized countries in per capita gross domestic product in terms of purchasing power parity (at constant 1990 prices) in three categories: low, middle (lower and upper) and high income. If a country caught at least 28 years in lower middle income level and at least 14 years caught in upper middle-income level, then they are trapped in lower middle and upper middle...
Infectious disease surveillance is one of the most valuable tools in monitoring COVID-19 pandemic. Here we examine components an ideal system and assess effectiveness North Carolina around world.
حدت استافیلوکوکوس اورئوس اساساً توسط پروتئینهای مرتبط با دیوارهی سلولی و ترشح توکسینها تعیین میگردد، که بیان آنها تا حد زیادی توسط سیستمهای تنظیمی دو جزئی (tcrss) مثل سیستمهای تنظیم ژنی فرعی (agr) و rap-trap تنظیم میشود. تاکنون چهار واریانت آللی از agr (agr i-iv) و trap (trap 1-4) شناسایی شده است. برخی از گزارشها اظهار داشتهاند که تمایلات بالینی بر طبق هر گروه agr وجود دارد، اما اطل...
having conducted the experiment and analysed the data, the researcher computed the groups mean scores and variances for the test relating to the research question. as the final atep, a t-test was conodonted for the hypothesis. as noted earlier, the significance level was determined at .05 and .01 respectively. the observed t-value was higher than the critical t-value at. 5 and .01 levels. conse...
One of the most vital problems in the storage and utilization of surface waters for drinking, flood control, hydropower, and agricultural purposes is that of sedimentation in reservoirs and subsequent decline of dam lifetime. The useful lifetime of a dam is defined as the time necessary for approximately 80% of the volume of its initial capacity to be filled by sediments washed in by water. It ...
Abstract Ecological engineering for pest suppression aimed at promoting ecosystem services of biological control, involves a range environmentally-benign approaches to conserve and promote arthropod natural enemies suppress populations, thus reduce the need insecticide use. Major components in rice management involve providing vegetation that favors parasitoid overwintering during fallow season...
The purpose of this in vitro study was to assess the effect of hydrogen peroxide on the antibacterial substantivity of chlorhexidine (CHX). Seventy-five dentine tubes prepared from human maxillary central and lateral incisor teeth were used. After contamination with Enterococcus faecalis for 14 days, the specimens were divided into five groups as follows: CHX, H(2)O(2), CHX + H(2)O(2), infected...
