Influencia del termociclado sobre la estabilidad del color de dos resinas compuestas
Influence of thermocycling on the color stability of two composite resins

Objetivo: Cuando las resinas compuestas son expuestas a procesos de envejecimiento naturales en boca, como es el ciclaje térmico, pueden sufrir un deterioro en sus propiedades ópticas. El objetivo de este estudio fue evaluar la influencia del envejecimiento térmico sobre la estabili...

Phytochemical and biological study of phenolic components from Geoffroea decorticans stem bark

The stem bark of Geoffroea decorticans (Gill.ex Hook. etArn.) Burk. was used medicinally to cure several skin affections; however, phytochemical and biological antecedents were not found. Analyses of purified methanolic extract from G. decorticans bark (PFGB), realized by silylation d...

Phytochemical profile, in vitro activities, and toxicity of optimized Eugenia uniflora extracts

In this study, we investigated the influence of mixture design on the chemical profile of Eugenia unifloraleaves, evaluating the antioxidant and antimicrobial activities, the toxic and hemolytic potential, with the focus on the improvement of the polyphenol’s extraction for in...

Determination of cyanide in whole seeds and brans of linseed (Linum usitatissimum Linn) by molecular spectrophotometry

Abstract The addition of linseed (Linum usitatissimum Linn) in the diet, as a functional food, has increased over the years. However, it possesses cyanogenic glycosides. This study aimed to quantify and compare cyanide concentration in whole seed and bran of brown and golden types to establish a safe lim...

Estudio de supervivencia de Streptococcus mutans en un tipo de fomite
Survival study of Streptococcus mutans in a type of fomite

Objetivo: Evaluar la supervivencia de Streptococcus mutans (S.mutans)en un tipo de fómite. Método: Se reactivó una cepa de S.mutans ATCC25175 criopre-servada en agar TYCSB. El inóculo se estandarizó en PBS buffer hasta obtener turbidez equivalente al 0,5 de Mc Farland y un OD = 0.01 por espectrofoto...

Efeito do probiótico lactobacilus casei adjunto a terapia periodontal em modelo experimental de periodontite: uma relação entre periodonto e intestino
Effect of the probiotic lactobacilus casei as an adjunct to periodontal therapy in an experimental model of periodontitis: a relationship between periodontium and intestine

A periodontite é uma condição crônica inflamatória que pode influenciar a microbiota intestinal. O tratamento padrão ouro para a periodontite inclui a raspagem e o alisamento corono-radicular (RACR), porém em casos complexos pode-se utilizar terapias adjuvantes, como os probióticos. A utilizaçã...
