1. Phytochemical profile, anti-inflammatory, antimutagenic and antioxidant properties of Acrocomia aculeata (Jacq.) Lodd. pulp oil
Abstract Acrocomia aculeata, known as macauba, is extensively distributed in the Southeast and Midwest of Brazil. Macauba fruit is used as food; however, its therapeutic properties are still poorly understood. The goal of the study was to investigate the chemical composition of macauba pulp oil (MPO) and anti-inflammatory, antimutagenic and antioxidant prope

2. Genome composition and pollen viability of Jatropha (Euphorbiaceae) interspecific hybrids by Genomic In Situ Hybridization (GISH)
Abstract Interspecific hybridization is required for the development of Jatropha curcas L. improved cultivars, due to its narrow genetic basis. The present study aimed to analyze the parental genomic composition of F1 and BC1F1 generations derived from interspecific crosses (J. curcas/J. integerrima and J. curcas/J. multifida) by GISH (Genomic In Situ Hybrid

4. CYTOTOXIC EFFECTS OF ARIPIPRAZOLE ON MKN45 AND NIH3T3 CELL LINES AND GENOTOXIC EFFECTS ON HUMAN PERIPHERAL BLOOD LYMPHOCYTES
RESUMO CONTEXTO: O câncer gástrico é conhecido como o quarto câncer mais comum. Os tratamentos atuais para o câncer danificaram os tecidos sensíveis do corpo saudável e, em muitos casos, o cancro será recorrente. Portanto, a necessidade de tratamentos que são mais eficazes é desejada. Recentemente, os pesquisadores mudaram sua atenção para os a

5. Biomonitors to evaluate the toxic potential of urban solid waste landfill leachate
Resumo O aumento acentuado da produção de resíduos sólidos urbanos (RSU) e o consequente acúmulo de lixiviado em aterros potencializam o risco de contaminação do meio ambiente. Biomonitores são utilizados para avaliação da toxicidade dos poluentes sobre os organismos vivos. Neste estudo, foram avaliados o potencial poluidor do lixiviado de RSU de u

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. Mycobacterium tuberculosis promotes genomic instability in macrophages
BACKGROUND Mycobacterium tuberculosis is an intracellular pathogen, which may either block cellular defensive mechanisms and survive inside the host cell or induce cell death. Several studies are still exploring the mechanisms involved in these processes. OBJECTIVES To evaluate the genomic instability of M. tuberculosis-infected macrophages and compare it

10. 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

11. Evaluation of the genotoxicity and mutagenicity of Ca3SiO5-based cement
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. However, no previous studies have evaluated the genot

12. Antigenotoxicity and antimutagenicity of ethanolic extracts of Brazilian green propolis and its main botanical source determined by the Allium cepa test system
Abstract Brazilian green propolis is a resinous substance prepared by bees from parts of the plant Baccharis dracunculifolia. As it possess several biological properties, this work assessed the cytotoxic/anticytotoxic, genotoxic/antigenotoxic and mutagenic/antimutagenic potential of ethanolic extracts of Brazilian green propolis (EEGP) and of B. dracunculifo
