Toxicidad, genotoxicidad y actividad anti-Leishmania de aceites esenciales obtenidos de cuatro (4) quimiotipos del género Lippia

Los aceites esenciales (AEs), pertenecientes al género Lippia, son candidatos interesantes de formulaciones tópicas en el tratamiento de la leishmaniasis cutánea (LC). El objetivo de este trabajo fue determinar el perfil toxicológico y la actividad anti-Leishmania de AEs obtenidos de plantas colo...

DNA damage in homocystinuria: 8-oxo-, 8-dihydro-2’-deoxyguanosine levels in cystathionine-β-synthase deficient patients and the in vitro protective effect of N-acetyl‑L‑cysteine

Clin. biomed. res; 38 (1), 2018
Introduction: Homocysteine (Hcy) tissue accumulation occurs in a metabolic disease characterized biochemically by cystathionine β-synthase (CBS) deficiency and clinically by mental retardation, vascular problems, and skeletal abnormalities. Previous studies indicate the occurrence of DNA damage secondar...

High consumption of sucrose induces DNA damage in male Wistar rats

An. acad. bras. ciênc; 89 (4), 2017
ABSTRACT The purpose of this study was to determine the effects of the high consumption of sucrose on the levels of DNA damage in blood, hippocampus and bone marrow of rats. Male Wistar rats were treated for 4 months with sucrose (10% for 60 initial days and 34% for the following 60 days) in drinking wat...

DNA damage in Wistar Kyoto rats exercised during pregnancy

Acta cir. bras; 32 (5), 2017
Abstract Purpose: To evaluate DNA damage levels in pregnant rats undergoing a treadmill exercise program. Methods: Wistar Kyoto rats were allocated into two groups (n= 5 animals/group): non-exercise and exercise. The pregnant rats were underwent an exercise protocol on a treadmill throughout pregnancy...

Comparisons of the effects of the sevoflurane and propofol on acute ischemia reperfusion and DNA damages in rabbits

Rev. bras. anestesiol; 67 (1), 2017
Abstract Background and objectives: The aim of this study was to compare the effects of sevoflurane and propofol anesthesia on oxidative DNA damage that occurs in low-extremity ischemia and is caused by tourniquet application. Methods: Fourteen New Zealand rabbits were randomly allocated into two equal...

Preliminary in vitro assessment of the potential toxicity and antioxidant activity of Ceiba speciosa (A. St.-Hill) Ravenna (Paineira)

ABSTRACT The bark tea of Ceiba speciosa, a tropical tree of the Malvaceae family, is used in the Northwestern Region of Rio Grande do Sul state, Brazil, to reduce blood cholesterol levels. However, there are no scientific data on the efficacy and safety of this plant. The aim of the present study was to ...

DNA damage and postural balance in multiple sclerosis patients

Fisioter. Mov. (Online); 30 (supl.1), 2017
Abstract Introduction: Multiple Sclerosis (MS) is a chronic inflammatory disease characterized by infiltration of inflammatory cells on the Central Nervous System (CNS). There is evidence that cumulative DNA damage can contribute to various mechanisms underlying MS lesions. Changes in postural balance a...

Principles and relevance of the comet assay

Desde hace varias décadas el ensayo Cometa, o electroforesis alcalina de células individuales, se ha convertido en un método establecido para el estudio del daño de ácido desoxirribonucleico, con múltiples aplicaciones en ensayos de genotoxicidad, estudios de biomonitoreo en humanos, epidemiologia ...

Evaluation of the genotoxicity and mutagenicity of Ca3SiO5-based cement

Braz. oral res. (Online); 30 (1), 2016
Abstract Ca3SiO5 is new cement based on the composition of Portland that has been developed to have superior physicochemical and biological properties. In a clinical evaluation, the cement did not appear to have cytotoxic properties and allowed for the proliferation of pulp cells and gingival fibroblasts...

Cytotoxicity and genotoxicity of calcium silicate-based cements on an osteoblast lineage

Braz. oral res. (Online); 30 (1), 2016
Abstract Several calcium silicate-based biomaterials have been developed in recent years, in addition to Mineral Trioxide Aggregate (MTA). The aim of this study was to evaluate the cytotoxicity, genotoxicity and apoptosis/necrosis in human osteoblast cells (SAOS-2) of pure calcium silicate-based cements ...
