menadione/dental caries

The susceptibility (MIC) of 44 strains of anaerobic bacteria isolated from the oral cavity and 3 standard strains to statherin and its C-terminal fragments with sequences QYQQYTF, YQQYTF, QQYTF, QYTF and YTF was determined by means of plate dilution technique in Brucella agar with 5% content of

In this study, the isolation, characterization, and identification of Bacteroides endodontalis is described. It was found that this asaccharolytic black-pigmented Bacteroides species is associated with infected dental root canals and oral submucous abscesses. B. endodontalis could be differentiated

The study of the sensitivity to tea tree oil (Australian Company TTD International Pty. Ltd. Sydney) was carried out on 193 strains of anaerobic bacteria isolated from patients with various infections within the oral cavity and respiratory tracts. The susceptibility (MIC) of anaerobes was determined

A spin trapping technique was used to analyze by electron spin resonance (ESR) the formation of oxygen-derived free radicals during the cerebral reductive metabolism of xenobiotics able to undergo a single electron reduction, i.e. quinones, pyridinium compounds and nitroheterocyclics. Paraquat,

The purpose of this study was to evaluate the effect of the presence or absence of amorphous, irregular smear layers on the adhesion of Prevotella nigrescens, to the dentin of the root canal by using scanning electron microscopy (SEM). Human incisors extracted within 7 days, with no cavities, no

Trypanothione reductase (TR) is both a valid and an attractive target for the design of new trypanocidal drugs. Starting from menadione, plumbagin, and juglone, three distinct series of 1,4-naphthoquinones (NQ) were synthesized as potential inhibitors of TR from Trypanosoma cruzi (TcTR). The three
