3. A sociedade de risco mundial e a responsabilidade penal das pessoas jurídicas : o papel das empresas e suas marcas como elementos indutores à conscientização ambiental
The world risk society is characterized for its negative dimension of equality, since citizens are not equal anymore for their rights or benefits that they share, but in detriment, for the common risks which they are exposed. The technological development as well as the scientific knowledge addressed the man to a modernity context promising to integrally acc

4. Biomonitoramento genÃtico de indivÃduos expostos ocupacionalmente a pesticidas no povoado Vila Bessa, municÃpio de ConceiÃÃo do JacuÃpe, Bahia / Genetic biomonitoring of individuals occupationally exposed to pesticides in the village Vila Bassa, municipality of ConceiÃÃo do JacuÃpe, Bahia
The high consumption of pesticides in Brazil and all over the world have lead researches to relate this exposition to possible genetic and health damages in rural workers. Studies reveal that cancer is considered a genetic disease, once it results of the mutation accrual in genes involved with control of proliferation and cellular differentiation or mutation

5. A exposição aguda ao chumbo induz danos no DNA de vários tecidos do peixe Prochilodus lineatus
Currently there are many works describing the presence of metal pollution in water bodies. Among these metals, lead (Pb) is considered a chemical of great environmental impact due to its high toxicity to live organisms and its wide use in the industrial process of many products. Considering its toxicity and the lack of knowledge concerning lead effects to ne

6. Neurotoxic activity and ultrastructural changes in muscles caused by the brown widow spider Latrodectus geometricus venom
Brown widow spider (Latrodectus geometricus) venom (BrWSV) produces few local lesions and intense systemic reactions such as cramps, harsh muscle pains, nausea, vomiting and hypertension. Approximately 16 protein bands under reducing conditions and ~ 14 bands under non-reducing conditions on a 12.5% sodium dodecyl sulfate-polyacrylamide gel electrophoresis w

7. Cytogenotoxicity biomarkers in fat snook Centropomus parallelus from Cananéia and São Vicente estuaries, SP, Brazil
The aquatic environment receives many contaminants that can induce damages at the molecular, biochemical, cellular and physiological levels. Centropomus parallelus , an important food resource for local populations, is a predator fish that feeds on small fishes and benthic invertebrates, thus being vulnerable to the bioconcentration and biomagnification pr

8. Avaliação do estresse oxidativo, genotoxicidade e mutagenicidade em trabalhadores expostos a tintas
Organic solvents and metals, widely used in paints, can lead to DNA damages and reactives species (RS) generation. The aim of this study was to evaluate possibles oxidative, genotoxic and mutagenic damages in 33 male workers exposed for at least six months to paint. To constitute the control group 29 healthy individuals were choosen, without paint exposure,

9. The use of the perturbative methods for the sensi-tivity analysis in hyperthermic problems caused by the laser sources in the treatment of tumors / Uso de métodos perturbativos para análise de sensibi-lidade em problemas de hipertermia causada por fontes de laser usadas no tratamento de tumores
The hyperthermic procedures available for therapeutic treatments of tumors can cause thermal damage in the adjacent living tissues and it is necessary to have an effective control systems. The temperature distribution inside the tissue must be controlled in order to avoid thermal damages to the healthy tissues in the neighborhood of the tumor. Numeri-cal sim

10. Planejamento, síntese e avaliação farmacológica de novos candidatos a protótipos de fármacos anti-inflamatários, desenhados a partir do nerolidilcatecol / Planning, synthesis and pharmacological evaluation of new candidates for prototypes of anti-inflamatários, drawn from the nerolidylcatechol
Inflammation is a local reaction of tissue involving neurological, vascular, humoral and cellular reactions to eliminate the causal agents and reduce the cellular damages. Prostaglandins, thromboxanes and leukotrienes are examples of chemical inflammation mediators, resulting for the action of the enzyme phospholipase A2 (PLA2). The PLA is a enzyme that hydr
