Effects of acetylsalicylic acid and acetic acid solutions in VX2 carcinoma cells. In vitro analysis
Purpose: To analyze, in vitro, the effects of acetylsalicylic acid (aspirin) and acetic acid solutions on VX2 carcinoma cells in suspension and to examine the correlation between these effects and neoplastic cell death. ...
Chemical communication in Apis mellifera: Temporal modulation of alarm behaviors
The effect of pheromones and their chemical analogues in honeybee alarm behaviors was studied in observation boxes. Defensive behaviors, as follows: a) attraction to scent source, b) elevation of wings in 'V', c) abdomen ...
Effect of an acid diet allied to sonic toothbrushing on root dentin permeability: An in vitro study
This study quantified alterations in root dentin permeability after exposure to different acid beverages. Twenty-five third molars were sectioned below the cementoenamel junction, the root segment was collected, and the ...
Voltammetric determination of ethyl acetate in ethanol fuel using a Fe 3+/Nafion®-coated glassy carbon electrode
A voltammetric method for the determination of ethyl acetate in ethanol fuel using a Fe3+/Nafion®-coated glassy carbon electrode (GCE) is proposed. The ethyl acetate present in the ethanol fuel was previously converted to ...
Effects of acetylsalicylic acid and acetic acid solutions on VX2 liver carcinoma in rabbits: in vivo analysis
(Sociedade Brasileira para o Desenvolvimento da Pesquisa em Cirurgia, 2007-08-01)
OBJETIVO: Analisar os efeitos das soluções de aspirina e de ácido acético, in vivo, em fígado de coelhos portadores de tumor hepático VX2, verificando o efeito histolítico e anatomo-patológico das soluções e eventuais ...
Highly selective acetalization of glycerol with acetone to solketal over acidic carbon-based catalysts from biodiesel waste
(Elsevier Sci Ltd, 2016)
The glycerol acetalization reaction in the presence of acetone was evaluated using acidic carbon-based catalysts from biodiesel waste as catalysts. Acidic carbon-based catalysts were prepared with different glycerin: ...
Indole ring oxidation by activated leukocytes prevents the production of hypochlorous acid
(Associação Brasileira de Divulgação Científica (ABRADIC), 2005-11-01)
Hypochlorous acid (HOCl) released by activated leukocytes has been implicated in the tissue damage that characterizes chronic inflammatory diseases. In this investigation, 14 indole derivatives, including metabolites such ...
