Antimicrobial endodontic compounds do not modulate alkylation-induced genotoxicity and oxidative stress in vitro
(2006-08-01)
Objective: To investigate if formocresol, paramonochlorophenol, or calcium hydroxide modulate the genotoxic effects induced by the oxidatively damaging agent hydrogen peroxide (H 2O 2) or the alkylating agent methyl ...
Determination of the position of the N-O function in substituted pyrazine N-oxides by chemometric analysis of carbon-13 nuclear magnetic resonance data
(Elsevier Science, 2013-07)
Investigations were carried out app lying NMR spectroscopy for the unambiguous determinatio n of the position of the N-oxide function in a set of 2-substitute d pyrazine N-oxides synthesized in our group. Applying chemometric ...
A Recycling-Focused Assessment of the Oxidative Thermomechanical Degradation of HDPE Melt Containing Pro-oxidant
(2019-12-21)
This study shows the effect of a pro-oxidant (oxo-biodegradable) additive on the oxidative thermomechanical degradation of high-density polyethylene (HDPE). It also allows us to predict the behavior of the material when ...
Ni-Nb mixed oxides: One-pot synthesis and catalytic activity for oxidative dehydrogenation of ethane
(Elsevier Science, 2014-06-20)
Ni–Nb mixed oxides were prepared by two methods, conventional evaporation method and combustion synthesis. With the latter technique, the mixed oxide can be quickly prepared from an aqueous solution of metal precursors ...
Influence of addition of calcium oxide on physicochemical properties of Portland cement with zirconium or niobium oxide
(2015)
Context: Calcium oxide (CaO) may be added to mineral trioxide aggregate (MTA) or Portland cement (PC) to improve physicochemical and biological properties. Aims: To evaluate the physicochemical properties of PC associated ...
Oxidative stress in dogs with periodontal disease: comparison of plasmatic and salivary biomarkers
(Arquivo Brasileiro Medicina Veterinaria Zootecnia, 2018-09-01)
Periodontal disease (PD) is the most common inflammatory disease of the oral cavity of dogs. Quantitation of plasma and salivary biomarkers have been used to assess the systemic oxidative stress (SOS) and local (LOS) of ...
