14. FUNCTIONAL PROTEOMICS OF CIRRHOSIS AND HEPATOCELLULAR CARCINOMA / ProteÃmica Funcional da Cirrose e do Carcinoma Hepatocelular
Introduction. Cancer is the most common given name to a series of molecular and physiological events which result in genetic instability and biochemical imbalance in cells. Among the seven events that drives cell cancer, the role of chronic inflammation and tumor microenvironment in cancer development were highlighted in this work . To experimentally evaluat

15. Micronucleated lymphocytes in parents of Down syndrome children
Down syndrome (DS) is the most common disease due to an autosomal aneuploidy in live born children and also the major known genetic cause of mental retardation. The risk of a DS pregnancy increases substantially with increasing maternal age. However, several women aged less than 35 years at conception have a child with DS. The micronucleus (MN) assay can ide

16. Análise e otimização da resposta em dinâmica de rotores
Great efforts are been made recently in order to diagnose vibrations in structures and equipments. Rotary machines require even greater attention, for they carry the risk of auto-excitation. This paper has as an objective the exposition a rotor dynamics methodology to minimize the response amplitude in the frequency domain. With this goal, the rotor is discr

17. Estudo das alteraÃÃes hematolÃgicas, bioquÃmicas e genotÃxicas induzidas por agrotÃxicos em agricultores do estado do Piauà / STUDY OF POSSIBLE GENETIC CHANGES INDUCED BY PESTICIDES IN FARMERS IN THE STATE OF PIAUÃ
Exposure to pesticides represents a potential risk to human health. In addition to poisoning, these compounds may interact with DNA, causing degenerative diseases, including cancer. The risk assessment for pesticides was conducted in the municipalities of Picos, Piripiri, Barras and Josà de Freitas with farm workers (exposed group) and 55 administrative off

18. Alterações sistêmicas e comportamentais de interesse odontológico em pacientes com síndrome de Down / Dental implications of systemic and behavior alterations in Downs syndrome patients
Downs syndrome (DS) is the most common genetic disorder and it is caused by the trissomy of 21 chromosome. It is characterized by mental retardation, physical alterations and several systemic co morbidities. The aim of this study was to evaluate behavior and systemic alterations with dental implications in DS patients and discuss the dental management of the

19. NAS CULTIVARES DE BATATA ASTERIX E ATLANTIC POR MARCADORES MORFOLÓGICOS E MICROSSATÉLITES / SOMACLONAL VARIATION IN CULTIVARS OF POTATO ASTERIX E ATLANTIC THROUGH MORPHOLOGICAL AND MICROSATELLITES MARKERS
A batata (Solanum tuberosum L.) ocupa o quarto lugar em nível mundial em produção, sendo superada apenas pelo trigo, arroz e milho. A cultura da batata é propagada de forma vegetativa e, devido à suscetibilidade a doenças, é imprescindível o emprego da cultura de ápices caulinares para efetuar limpeza clonal e, na sequência, da micropropagação da

20. Caracterização molecular de recombinantes intersubtipos do vírus da imunodeficiência humana tipo 1(HIV-1) em pacientes provenientes da epidemia do estado de São Paulo. / Molecular characterization of recombinant intersubtipos of human immunodeficiency virus type 1 (HIV-1) in patients from the epidemic in the state of Sao Paulo, Brazil.
The extensive HIV-1 genetic diversity has several implications on the viral adaptive and evolutionary capabilities. This diversity is due to intensive mutational rates derived from error-prone activity of viral reverse transcriptase and RNA genomic instability, generating a highly diverse and heterogeneous viral population named quasispecies. However, even t

22. Genomic instability in human actinic keratosis and squamous cell carcinoma
OBJECTIVE: To compare the repetitive DNA patterns of human actinic keratoses and squamous cell carcinomas to determine the genetic alterations that are associated with malignant transformation. INTRODUCTION: Cancer cells are prone to genomic instability, which is often due to DNA polymerase slippage during the replication of repetitive DNA and to mutations i

High available aluminium and low levels of calcium below the ploughed zone of the soil are limiting factors for agricultural sustainability in the Brazilian Cerrados (Savannahs). The mineral stresses compound with dry spells effect by preventing deep root growth of cultivated plants and causes yield instability. The mode of inheritance for grain yield and mi

24. Avaliação das propriedades antigenotóxicas e antioxidantes do flavonóide quercetina e dos carotenóides bixina e norbixina contra os danos no material genético e distúrbios do estado redox causados pelo cloreto de mercúrio e metilmercúrio, in vitro e in vivo / Evaluation of antigenotoxic and antioxidant properties of the flavonoid quercetin and of the carotenoid bixin and norbixin against DNA-damage and alterations of redox status induced by mercury chloride and methylmercury, in vitro and in vivo
Mercury (Hg) is one of the most hazardous metals in the environment and the major process responsible for its toxicity is oxidative damage; its organic form methylmercury (MeHg) presents the highest toxicity. The main way of exposition to Hg is through inhalation by workers occupationally exposed in several industries and/or through consumption of fishes and
