1. 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

2. Morphological characterization of mitochondrial alterations in hepatic steatosis of cause not defined in childhood group / Caracterização morfologicas das alterações mitocondriasis na esteatose hepatica de causa não determinada em grupo pediatrico
Hepatic steatosis unrelated to alcoholism may occur separately or be part of fatty liver disease (NAFLD). It encompasses a wide spectrum of morphologic alterations, ranging from steatosis to a more severe stage accompanied by fibrosis and cirrhosis. The aim of our study was to assess and characterize childhood steatosis of not defined cause carrying out morp

3. Características ultraestruturais de ovócitos ovinos durante a maturação in vitro
O objetivo deste trabalho foi descrever e avaliar, através da análise de aspectos ultraestruturais, o processo de maturação in vitro (MIV) de ovócitos ovinos por um período de 24 horas após a inserção de ovócitos imaturos no meio de maturação. Para isso, foram coletados ovários de abatedouro, sendo os folículos aspirados no laboratório. Os com

4. Production, morphologic and ultra-structural analyses of Passiflora spp. callus. / ObtenÃÃo, anÃlises morfolÃgicas e ultra-estruturais de calos de Passiflora spp.
Brazil occupies a position of prominence in the passion fruit plant culture, being the largest world producer of passion fruit. In the last years, the increasing demand resulted in a expansion of the planted area resulting in the expansion and appearance of many diseases. Some species not cultivated, as Passiflora gibertii N. E. Brown and Passiflora edulis e

5. Síntese, caracterização e fotoatividade de fotossensibilizadores derivados de protoporfirina IX e de clorofilina / Synthesis, characterization and photoactivity of photosensitizers derivatived from protoporphyrin IX and chlorophyllin
Processos que envolvem sensibilização são extremamente importantes para diversas áreas do conhecimento, incluindo a biologia, a química e a medicina. A aplicação de sensibilização em medicina tem se destacado, especialmente, em face de uma modalidade alternativa de tratamento de câncer denominada terapia fotodinâmica (TFD). Uma das linhas de pesqu

6. Estudo morfológico ultraestrutural e imuno-histoquímico da influência do excesso de flúor no desenvolvimento do germe dental de incisivo de rato / Morphological ultrastructural and immunohistochemical study of the fluorine excess influence on rat incisor tooth germ development
The dental fluorosis is a result of fluorine toxicity during odontogenesis. Several experimental models have been used in attempt to explain the fluorine pathogenesis in enamel, but during the fetal or the initial postnatal period, there is not much information about its action. For this reason, in this research, the female rats received 0, 7 or 100 ppm of s

7. Origin, evolution and targeting of THI1 protein in plants. / Origem, evolução e direcionamento da proteína THI1 em plantas.
THI1 is probably a bifunctional protein, since it is involved in thiamin biosynthesis and organelar genome stability mainly the mitochondrial. Interestingly, the thiamin biosynthesis occurs at different compartments in plants (chloroplasts) and yeasts (mitochondria). Functional complementation assays showed that Arabidopsis thaliana thi1 gene is able to comp

8. Fibromatose gengival hereditaria : aspectos morfologicos e ultraestruturais
The ultrastructure of the gingival connective tissue was analysed in 12 patients bearing Hereditary Gingival Fibromatosis (H.G.F.) and compared with normal gingival tis sue from biopsies of 08 volunteers. Some fibroblasts appeared as normal cells, but most of these cells showed minor to severe altered features, up to signs of cell desintegration the main alt
