13. Toxicidade em camundongos devido à exposição prolongada a uma floração de cianobactérias contendo microcistinas: avaliações comportamental, hematológica, bioquímica e anatomopatológica / Toxicity in mice due to prolonged exposure to a cyanobacterial bloom containing microcystins: behavioral, hematological, biochemical and anatomopathological evaluations
Cyanobacteria (blue-green algae) are prokaryotic and photosynthetic organisms found in practically every type of liquid habitat and that can form great superficial masses of intense green color called blooms. The development of algal blooms on water surface occurs with a higher incidence and is recognised as being a potential health hazard due to the toxic n

14. Aspectos do envelhecimento cerebral e função cognitiva em modelo experimental animal e estudo de mecanismos de neurodegeneração em cultura celular
The two phenomena, biological and behavioural, approached in the present work are brain aging and spatial memory. Several studies, comparative and experimental, have shown that aged subjects present significantly impaired performances in different types of cognitive tasks. It is also known that contradictions in literature exist in relation to consequences o

15. Biochemistry answer of caterpillars of Thyrinteina leucoceraea (Lepidoptera: Geometridae), fed with the serine-proteinases inhibitor benzamidine / Resposta bioquímica de lagartas de Thyrinteina leucoceraea (Lepidoptera: Geometridae), submetidas ao inibidor de serinoproteases benzamidina
The insects may cause considerable losses to plants, necessitating the control of these pests. However, some insects inhabit plants without causing considerable losses. For example, Thyrinteina leucoceraea, native insect, inhabit guava plants, native Myrtaceae harbor, and dont need to be controled. The Eucalyptus ssp., however, is a novel Myrtaceae host in B

16. AVALIAÇÃO TOXICOLÓGICA CRÔNICA DO POLÍMERO QUITOSANA FERRO(III) SOLÚVEL / CHRONIC TOXICOLOGY AVALIATION OF SOLUBLE IRON (III) CHITOSAN
Hyperphosphatemia is a common problem in patients with chronic renal failure, particularly in those who have reached end-stage renal diseased. The main methods of achieving control of the increased of phosphate are reduction of dietary intake, reduction of gastrointestinal absorption by use of binding agents and removal by dialysis. In this study, we evaluat

18. Development and application of procedures envelopemend chemiluminescent reactions in flow for determination of analytes of interest in food, pharmaceutical and biochemistry. / Desenvolvimento e aplicação de procedimentos envolvendo reações quimiluminescentes em fluxo para a determinação de analitos de interesse alimentício, farmacêutico e bioquímico.
In this work, analytical flow procedures were developed using multicommutation concept and chemiluminescent detection for the determination of hydrogen peroxide, glucose and cholesterol in food, biochemistry and pharmaceutical samples. A personal computer Pentium 233 MHz equipped with PCL 711S interface was employed to control the flow manifold and data acqu

20. Estabilidade oxidativa do colesterol em ovo integral em pó e em macarrão contendo ovos medida através do 7-cetocolesterol livre / Cholesterol oxidative stability in whole egg powder and pasta with eggs measured by free 7-ketocholesterol
O ovo é importante como alimento e matéria-prima industrial. O ovo é rico em colesterol que, por sua vez, está sujeito à oxidação, formando-se óxidos tóxicos. O presente trabalho teve como objetivos, a avaliação da formação do 7-cetocolesterol livre em ovo integral em pó e em macarrão contendo ovos, e a verificação da estabilidade oxidativa

22. Análise da resposta antioxidativa de células de Nicotiana tabacum cv BY-2 submetidas ao cádmio. / Antioxidant response of by-2 Nicotiana tabacum cells to cadmium stress.
The contamination of environments by heavy metal pollution, mainly by cádmium (Cd), considered one of the more toxic, is generated by mining and industrial activities, and sewage sludge and phosphated fertilizers used in agriculture. The latter contains Cd in its composition and with continuous agricultural utilization an increase in the heavy metals levels
