13. Metalloporphyrins and salen complexes as a P450 biomimetic model for the metabolism of antiepileptic and antidepressant drugs / Metaloporfirinas e compostos salen como modelos biomiméticos do citocromo P450 no metabolismo de fármacos anticonvulsivante e antidepressivo
In this work, the catalytic activities of metalloporphyrins and the salen complex (Jacobsen catalyst) in solution and immobilized on different supports were studied in the oxidation of hydrocarbons, anticonvulsivant drugs (carbamazepine and primidone) and antidepressives (fluoxetine) by the following oxygen donors: hydrogen peroxide, terc-butyl hydroperoxide

15. Avaliação da resposta clínica e imunológica local de pacientes com neoplasia intra-epitelial cervical graus II e III tratadas com interferon alfa-2b intralesional.
Introduction: HPV is a DNA virus of tape double which can infect the lower genital tract. Its persistence, especially with oncogenic types is highly associated with the development of the high-grade squamous intraepithelial lesions. Treatment of these lesions is usually excisional (cold conization, laser conization, diathermic conization) and some studies ha

16. Estudo de monocamadas fosfolipidicas nanoestruturadas obtidas por LB para aplicações em biossensores
There has been long-standing interest in the physical chemical properties of defined mixtures of cholesterol and phospholipids in monolayer and bilayer membranes. They also provide insight into certain properties of the membranes of animal cells. Even if phospholipids and sphingolipids build up the matrix of cellular membranes, sterols are essential componen

17. Obtaining a fluorescent and resistant hybrid yeast to the nystatin / Obtenção de levedura híbrida fluorescente e resistente a nistatina
Vats contamination by wild yeasts can harm the efficiency and the productivity of ethanol industrial production and there are not efficient methods to control this type of contamination. Easiness, speed and the low cost would be desirable characteristics for the control of yeasts that eventually contaminate the fermentation process. With this aim, TAVARES (1

18. Herpesvirus simplex Type 1 (HSV-1) in marmosets (Callithrix jacchus and Callithrix penicillata) - Pathological and molecular characterization / Herpesvirus simplex Tipo 1 (HSV-1) em sagüis (Callithrix jacchus e Callithrix penicillata) - Caracterização anatomopatológica e molecular
The introduction of wild animals in the conviviality with humans represents serious risk to the health of both. The objective of this work was to prove the hypothesis of the HSV-1 is the agent of vesicular and ulcerative lesion in the skin and mucous membranes, associated with neurological signs observed in marmosets in Brazil. Six white-tufted-ear marmosets

19. Filmes híbridos orgânico-inorgânicos a partir de óleo de soja funcionalizado
Organic-inorganic hybrids materials can be prepared by the sol-gel process and have applications in biomaterials, catalysis, optics, membranes, chromatography, electrochemistry and coatings. Vegetable oils can be used as organic component for the preparation of these materials and, as they are biodegradable and obtained from natural and renewable sources, th

20. Regulation of insulin secretion in islets from rats submitted a low protein diet and leucine supplementation / Regulação da secreção de insulina em ilhotas de Langerhans de ratos submetidos a restrição proteica e suplementados com leucina
We think that intra-uterine mal nutrition and after birth produce morphological and changes in endocrine pancreas and in peripheric tissue that translate insulinopenia and insulin resistance. Based on these complications we have evaluated in this work the insulin secretion regulation in Langerhans islets from rats and mice fed a low protein diet and suppleme

21. Caracterização de microdomínios de membrana resitentes a detergente não iônico em promastigotas de Leishmania (Viannia) braziliensis. Papel dos microdomínios na infectividade. / Characterization of non-ionic detergent resistant membrane microdomains in Leishmania (Viannia) braziliensis promastigotes. Role of these microdmains in the infectivity
Glycoconjugates present in Leishmania surface are an important class of molecules involved in parasite-macrophage interaction. The structural elucidation of Leishmania (Viannia) braziliensis promastigote glycolipids is very relevant because in this specie the glycolipids represent the major promastigote surface glycoconjugate. Six glycolipid fractions, terme

22. Purificação de anticorpos monoclonais anti-TNP do isotipo IgG1 utilizando cromatografia em membranas de afinidade com ions metalicos imobilizados
Monoc1onal antibodies are immunoglobulins produced by a hybrid cell ca11ed hybridoma. These cells result from the fusion of lymphocytes with malignant myeloma cells. Hybridomas cells express both the lymphocyte s property of specific-antibody production and the immortal character of the myeloma cells. Monoc1onal antibodies have been used in analy1ica1 and th

23. Cytokeratin-containing cells in proliferative diabetic retinopathy membranes.
Immunohistochemical techniques were used to investigate the relation between retinal pigment epithelial cells (RPE), traction retinal detachment (TRD) membranes, and combined traction rhegmatogenous retinal detachment (CTR) membranes in proliferative diabetic retinopathy. Seven CTR and five TRD membranes were obtained during closed microsurgery. Six of the s

24. Supported phospholipid/alkanethiol biomimetic membranes: insulating properties.
A novel model lipid bilayer membrane is prepared by the addition of phospholipid vesicles to alkanethiol monolayers on gold. This supported hybrid bilayer membrane is rugged, easily and reproducibly prepared in the absence of organic solvent, and is stable for very long periods of time. We have characterized the insulating characteristics of this membrane by
