1. Mutagenic damage among bronchiectasis patients attending in the pulmonology sector of a hospital in southern Brazil
SUMMARY OBJECTIVE: Bronchiectasis is a chronic respiratory disease characterized by inflammation, irreversible dilation of the bronchi, and recurrent pulmonary infections, with a high morbidity and mortality rate, but is less studied from the point of view of its prevalence and associated factors not directly related to respiratory prognosis. As it is a dis

3. Protective effects of bark ethanolic extract from Spondias dulcis Forst F. against DNA damage induced by benzo[a]pyrene and cyclophosphamide
Abstract This study evaluated the genotoxicity, mutagenicity, antigenotoxicity, and antimutagenicity effects on biochemical parameters of oxidative stress of the Spondias dulcis bark ethanolic extract on mice. The extract was evaluated in the doses of 500, 1000, and 1500 mg/kg bw via gavage. To evaluate the protective effects of the extract, benzo[a]pyrene (

5. RESISTANCE EXERCISE PROTOCOL DOES NOT CAUSE ACUTE GENOTOXIC EFFECTS IN TRAINED INDIVIDUALS
RESUMO Introdução: O treinamento resistido, principalmente a musculação, vem progressivamente ganhando novos adeptos em todo o mundo. Apesar de haver um significativo aumento no número de pesquisas e na literatura disponível sobre o assunto, o treinamento resistido vem passando por um importante processo de evolução. O metabolismo anaeróbico, que c

6. The pequi pulp oil (Caryocar brasiliense Camb.) provides protection against aging-related anemia, inflammation and oxidative stress in Swiss mice, especially in females
Abstract Continued exposure to reactive oxygen species and inflammation are the rationale behind aging theories and associated diseases. Scientific evidence corroborates the ethnomedicinal use of the oil of pequi (Caryocar brasiliense Camb.), a typical Brazilian Cerrado fruit, against oxidative damage to biomolecules and inflammation. We aimed to investigate

7. In Vitro Study Towards Role of Acrylamide-Induced Genotoxicity in Human Lymphocytes and the Protective Effect of L- Carnitine
ABSTRACT Acrylamide (AA), is an important industrial compound, formed during food processing under high temperature. Due to its potential carcinogenic effect, it has been recognized as a human health concern. In this study, we investigated the role of oxidative stress in acrylamide’s genotoxicity and protective role of L- carnitine (LCA) in human lymphocyt

8. Influence of hesperidin and vitamin C on glycemic parameters, lipid profile, and DNA damage in rats treated with sucrose overload
ABSTRACT We evaluated the influence of hesperidin and vitamin C (VitC) on glycemic parameters, lipid profile, and DNA damage in male Wistar rats treated with sucrose overload. Rats were divided into six experimental groups: I-water control; II-sucrose control; III-hesperidin control; IV-VitC control; V-co-treatment of sucrose plus hesperidin; VI-co-treatment

9. High consumption of sucrose induces DNA damage in male Wistar rats
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 water, and then, glycemia and glycated hemoglobin (A1C) we

10. Short-term carcinogenesis evaluation of Casearia sylvestris
Abstract Casearia sylvestris Sw., Salicaceae, is an important medicinal plant widely used in Brazil for the treatment of various cardiovascular disorders. This species was included as of interest by Brazilian Unified Health System. Although preclinical studies described cardiovascular protective effects and apparent absence of toxicity, no studies have evalu

11. Antigenotoxicity protection of Carapa guianensis oil against mitomycin C and cyclophosphamide in mouse bone marrow
ABSTRACT The aim of this study was to evaluate the possible protective of C. guianensis oil against MMC and CP, which are direct- and indirect-acting chemical mutagens, using the micronucleus test. Three experiments were performed. First the C. guianensis oil was co-administered to mice at doses of 250, 500 and 1000 mg/kg bw with 4 mg/kg bw MMC or 50 mg/kg b

12. Genotoxic and mutagenic effects of polluted surface water in the midwestern region of Brazil using animal and plant bioassays
Abstract This study aimed to evaluate DNA damage in animal and plant cells exposed to water from the Água Boa stream (Dourados, Mato Grosso do Sul, Brazil) by using bioassays, and to identify the chemical compounds in the water to determine the water quality in the area. Through the cytotoxicity bioassay with Allium cepa, using micronucleus test, and comet
