13. Perfil diário e os mecanismos de produção de melatonina pela glândula pineal de ratos diabéticos por estreptozotocina. / Pineal melatonin production in Streptozotocin-diabetic rats: mechanisms and microdialysis daily profile.
A pineal participa da sincronização do organismo pela síntese de melatonina. Diabetes é um distúrbio metabólico caracterizado por hiperglicemia. Diante da controvérsia sobre a síntese de melatonina em animais diabéticos, esse trabalho objetivou avaliar as alterações da glândula pineal mediante o diabetes induzido por STZ (60mg/kg, i.p.). Ratos wi

14. O COMPLEXO METILMERCÚRIO-CISTEÍNA ALTERA O ACÚMULO DE MERCÚRIO EM DIFERENTES TECIDOS DE CAMUNDONGO / COMPLEX METHILMERCURY CYSTEINE ALTERS MERCURY ACCUMULATION IN DIFFERENT TISSUES OF MICE
Methylmercury (MeHg) is related to several deleterious effects on the vertebrate tissues, mainly on central nervous system, and part of these effects are through of interaction with sulfhydryl group found in cellular proteins. MeHg interacts with low and high molecular weight thiols in the blood and tissues and this fact, in some cases will allow a better ab

15. Atividade Anti-helmíntica e imunomoduladora de extratos de Cocos nucifera L. / Anthelmintic activity and immunomodulating extract of Cocos nucifera L.
The development of resistance to synthetic anthelmintic required the search for alternatives for control of gastrointestinal nematodes. Among these, there is the use of medicinal plants. The liquid from the bark of the green coconut (LBGC) was extracted from Cocos nucifera L, followed by obtaining the butanol extract from LBGC. The objectives of this study w

16. Avaliação da função e plasticidade celuar de ilhotas pancreaticas em modelo de resistencia a insulina induzida por dexametosa em ratos / Analysis of dexamethasone treatment effcts on insulin secretion, molecular and biochemical parameters in submitted to protein restriction
Introduction and aims: Insulin binds to plasma membrane receptors leading to a variety of cellular responses. Malfunction in any of the insulin cell signalling pathways in target tissues may lead to several conditions and diseases, like hyperglycemia, insulin resistance and type 2 diabetes mellitus (T2DM). These effects may be experimentally reproduced using

17. FAK interage com MEF2 e ativa região intronica regulatoria do fosfolamban em resposta ao estimulo mecanico / FAK interacts with MEF2 and drives the stretch-induced activation of an intronic enhancer of phospholamban gene in cardiomyocytes
Estudos anteriores demonstraram que em miócitos cardíacos submetidos a estímulos mecânicos ocorre pronta fosforilação e ativação da FAK. Resultados de estudos recentes, realizados em corações de ratos indicaram que em resposta a estímulos mecânicos, a FAK, além de ser ativada, localiza-se no núcleo dos miócitos cardíaco. Estudos conduzidos em

18. Estudo dos mecanismos de ação da hidroquinona e fenol sobre o recrutamento leucocitário em respostas inflamatórias / Study of mechanisms of action of hydroquinone and phenol on leukocyte recruitment in inflammatory response
Hydroquinone (HQ) is one of the metabolites of benzene responsible for the toxic effects of exposure to solvent, as well as being part of the diet, medicines, tobacco and polluting the environment. Considering the immunotoxicity of this substance, our laboratory has investigated the role of exposure to HQ by prolonged period of time on acute inflammatory res

19. Immunohistochemical characterization of the chick marginal retina
The retina is a highly differentiated tissue with a complex layered structure that has been extensively characterized. However, most of the previous studies focused on the histology of the central retina while little is known about the cellular composition, organization and function of the marginal retina. Recent research has identified a subpopulation of mu

20. AvaliaÃÃo da Qualidade de Voz do ServiÃo VoIP em Sistemas HSDPA / Evaluation of the quality of voice of the VoIP service in systems HDSPA
In recent years, we can observe the development and fast dissemination of VoIP services, being integrated by the present market, beside conventional telephony and cellular networks. For being a technological alternative that contributes to minimize costs, we see an increasing preference for voice transmission through IP networks. HSDPA, as a cellular system,

21. Estudo do efeito da fraÃÃo nÃo dialisÃvel do lÃtex de Calotropis procera (ait) R. Br em modelos experimentais de inflamaÃÃo, com Ãnfase em artrite / Study of the effect of the non-dialyzable fraction of Calotropis procera (Ait) R. Br latex in experimental models of inflammation, with emphasis in arthritis
The objective of this dissertation was to investigate the effect of the latex from Calotropis procera in experimental models of inflammation, with special focus on arthritis. The plant belongs to Asclepiadaceae family and is largely found in Northeast of Brazil. The plant latex presents clear anti-inflammatory effects, which is kept by its non-dialyzable pro

22. Identificação de interações proteína-proteína entre NS5 do vírus da febre amarela e proteínas celulares.
Yellow fever is an infectious disease caused by the yellow fever virus (YFV), a Flavivirus transmitted to humans by Aedes aegypti mosquitoes. Despite the existence of the yellow fever vaccine, the disease is endemic in South America and Africa, causing public health problems such as dispersed outbreaks, epidemics with variable impact and the risk of re-emerg

23. Effect of pentoxifylline on lung inflammation and gas exchange in a sepsis-induced acute lung injury model
Experimental models of sepsis-induced pulmonary alterations are important for the study of pathogenesis and for potential intervention therapies. The objective of the present study was to characterize lung dysfunction (low PaO2 and high PaCO2, and increased cellular infiltration, protein extravasation, and malondialdehyde (MDA) production assessed in broncho

24. SYSTEMIC ADMINISTRATION OF SPERMIDINE AND ARCAINE ALTERS MEMORY OF THE INIBITORY AVOIDANCE TASK IN RATS: STATE DEPENDENCE INVOLVIMENT. / ADMINISTRAÇÃO SISTÊMICA DE ESPERMIDINA E ARCAÍNA ALTERA A MEMÓRIA DA TAREFA DE ESQUIVA INIBITÓRIA EM RATOS: ENVOLVIMENTO DA DEPENDÊNCIA DE ESTADO
The polyamines, putrescine, spermidine and spermine, are present in high concentrations in the central nervous system and, because of their policationic nature, they can interact with diverse cellular anionic targets (nucleic acids and proteins) and modulate the learning and memory by interacting with the polyamine binding site at N-methyl-D-aspartate recept
