introduction: the success of endodontic treatment depends on the method and quality of cleaning, disinfection and three-dimensional sealing of the root canal. the smear layer can play an important role in the success or failure of endodontic treatment. there is controversy over the presence or removal of the smear layer in relation to the success or failure of endodontic treatment. this study u...

conclusions our study showed high esbl incidence, with ctx-m genotype as the emerging strain in our hospitals. high co-resistance to other non-β-lactam antibiotics is a major challenge for the management of esbl infections. results the esbls were found in (62.89%) of e. coli and (67.5%) of k. pneumoniae isolates. the majority of the typeable isolates harbored two or more esbl genes (73%). overa...

introduction: the purpose of this study was to compare the ability of proroot mineral trioxide aggregate (pmta) and root mineral trioxide aggregate (rmta) as root-end filling materials, and portland cement (pc) to prevent bacterial leakage through filled root end cavities. materials and methods: fifty-one extracted human single rooted teeth were cleaned and shaped using a step back technique. t...

agrobacterium rhizogenes (pri), a causative agent of hairy root disease, effectively induces hairy root formation in a variety of plant species. in our study four bacterial strains ar15834, a4, 9435 and c318 and three explants types leaf, stems and roots, were examined. hairy roots were induced from roots, stems and leaf explants. the highest transformation efficiency of 77% was achieved by usi...

the aim of this study was to assess the effects of nucleotide on intestinal microbiota of striped catfish, pangasianodon hypophthalmus . different levels of the nt (0, 0.25. 0.5, 0.75 and 1 % weight per weight, ww -1 ) were added to basal diet and then randomly allocated to triplicate groups of fish with average initial weight (1.52±0.11 g) for 10 weeks. at the end of the experiment, at least 1...
