abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
Canal wall brushing, accomplished by a tractor-mounted custom-designed rotating metal brush, was an effective means of removing nuisance periphytic cyanobacterial growth and consequently reducing MIB and geosmin production in the Arizona Canal, a major water conveying open channel in the metropolitan Phoenix (Arizona) water supply system. On average, c. 80% of the periphyton biomass was removed...

Background: Stainless steel instruments have long used as conventional instruments applied in root canal therapy procedures. Being difficult the canal preparation by these instruments, a new generation of nickel-titanium instruments have introduced. The aim of this study was to compare the manual Ni-Ti instruments with the Flex Master® Ni-Ti rotary system in canal preparation. Materials & M...
introduction: adequate root canal seal following retreatment is essential for a successful outcome. resilon/epiphany (r/e) obturation system has been introduced as a substitute for conventional gutta-percha/sealer method. this in vitro study compared the amount of apical microleakage of r/e with gutta-percha/ah26 (gp/ah26) sealer as secondary root canal filling following retreatment in human te...
