background and aim: bacterial elimination from root canal system is one of the aims in endodontic treatments, so the addition of antibiotics to sealers can increase their antimicrobial efficacy, as in this study we are determining the in-vitro antimicrobial effect of ah26 and ah plus sealers mixed with amoxicillin, triple antibiotic pastes and nanosilver on enterococcus faecalis. materials and ...

introduction: antibiotic supplements are regularly used in neuronal culture media to control contamination however, they can interfere with the neuronal excitability and affect electrophysiological properties. therefore, in this study, the effect of penicillin/streptomycin supplements on the spontaneous electrophysiological activity of hippocampal pyramidal neurons was examined. methods: electr...

OBJECTIVE The objective was to investigate the effect of intracanal antibiotic medicaments followed by ethylenediaminetetraacetic acid (EDTA) on the indentation properties and hardness of radicular dentin using a BioDent reference point indenter and a traditional microhardness technique, respectively. MATERIALS AND METHODS Specimens with intact root canal dentin surfaces and polished radicula...

A strain of actinomycetes identified as Saccharothrix sp. SANK 64289 was found to produce new antibiotics, galacardins A and B. Their physico-chemical properties showed that they were new members of glycopeptide antibiotics. They were structurally related to beta-avoparcin but differed from it only in sugar composition. Though beta-avoparcin does not contain galactose, galacardins A and B did c...

Isolation, purification and physicochemical properties of the antibiotic complex YA-56, a family of phleomycin-bleomycin group, are described. The antibiotic YA-56 complex was found to be composed mainly of two active components named YA-56X and Y. These components were clearly differentiated from the reported phleomycins and bleomycins by their physicochemical properties. However, by direct co...

Lactoferrin (Lf), a mammalian iron scavenging defense protein, constitutively is present in exocrine secretions that consistently are exposed to microbial flora: milk, tears, tubotympanum and nasal exudate, saliva, bronchial mucus, gastrointestinal fluids, cervicovaginal mucus, and seminal fluid. Additionally, Lf is promptly delivered by circulating neutrophils to sites of microbial invasion. A...

In the previous paper1}, we presented a preliminary report on a new water-soluble antibiotic 5879 produced by Streptomyces No. 5879. Differences in the taxonomic properties of the strain from those of recognized species were considered to be significant enough to propose the new species Streptomyces aizunensis nov. sp. for this strain, and antibiotic 5879 was named aizumycin. This report deals ...

introduction: the purpose of this study was to compare the setting time and post-setting solubility, flow, film thickness and dimensional changes of ah26 root canal sealer with ah26-antibiotic combination. materials and methods: this study was performed according to british standard bs 6876 (2001) which tests the physicochemical properties of endodontic sealers. three samples of each of tested ...
