13. Restrição alimentar intra-uterina e suas repercussões sobre o desenvolvimento da termorregulação da prole.
Background: Previous study from our laboratory has shown that intrauterine food restriction (IUFR) delayed thermoregulation of the newborns. In neonates brown adipose tissue (BAT) is essential for thermogenesis mainly due to the presence of uncoupling proteins (UCPs) and their expression can be modified by action of hormones such as thyroid hormone, leptin a

14. Avaliação dos níveis de metais no organismo de ratos portadores de tumor de Walker-256 e camundongos portadores de Trypanosoma cruzi pela técnica de fluorescência de raios X portátil (PXRF)
Parte 1: Nos últimos 25 anos foram desenvolvidas técnicas não invasivas para determinação de concentrações de metais in vivo. Aprimoramentos tecnológicos recentes permitem que a técnica de Fluorescência de Raios X Portátil (PXRF) tenha sensibilidade suficiente para diagnósticos ou monitoramento em aplicações biomédicas. Uma aplicação potenci

15. Relação entre fatores morfofisiológicos e indicadores de desempenho derivados do modelo de carga crítica na natação em ratos wistar
O teste de Potência Crítica (PC) tem sido muito usado nos últimos anos, e vários estudos vêm buscando compreender o real significado fisiológico de seus índices aeróbio e anaeróbio. Testes realizados até exaustão na intensidade do índice aeróbio obtido por esse modelo de PC foram realizados, entretanto, as variáveis fisiológicas medidas durant

16. Repair process of surgical defects filled with autogenous bone grafts in tibiae of diabetic rats
From a biological standpoint, the best material for reconstruction of bone defects is the autogenous bone graft. However, as tissue healing is affected under diabetic conditions, major changes might take place in the revascularization, incorporation, replacement and remodeling phases of the grafted area. The purpose of this study was to assess the bone heali

17. Evaluation of the mechanisms responsible for reproductive damage in diabetic rats / Avaliação dos mecanismos causadores de disturbios reprodutivos em ratos diabeticos
Diabetes mellitus is usually related with some kind of sexual dysfunction, promoting infertility in humans as well as in experimental models. In a prior work from our laboratory, male rats, which had a diabetic-induced state of hyperglycemia caused by streptozotocin administration, demonstrated reduced fertility through several parameters analyzed. The prese

18. Experimental autotransplant of spleen / Autotransplante experimental de baço
The spleen is a lymphoid organ that plays important part in the organism defense, participating in filtration processes, phagocytosis and immunoglobulin production. Histologically, is formed by a stroma and the parenquima being its cellular arrangement differentiated in white and red pulps. The main cellular types in the splenic structure are: T and B lympho

19. Conflitos e interesses acerca do controle da experimentação animal no Estado de São Paulo / Conflicts and interests about the control over animamal State of São Paulo
A presente dissertação tem por objetivo analisar as idéias e o comportamento político dos atores sociais que participaram, em diferentes momentos, da controvertida elaboração de leis acerca do controle sobre a experimentação animal realizada no Brasil. Busca compreender quais foram as táticas políticas e os princípios éticos que condicionaram o c

20. Imunolocalização de CSF-1, OPG e RANKL no periodonto relacionado ao esmalte de incisivos de ratos em erupção normal e contida / Immunolocalization of CSF-1, OPG and RANKL in the enamel-related periodontium of rat incisors in normal and immobilized eruption
In the rat incisors the face of the socket related to the enamel is resorpted continually on the inner side and formed on the outer side. A study accomplished at our laboratory showed that in rat incisors immobilized by a period of 18 days, there is a replacement of bone resorption in the face of the socket related to the enamel by bone formation, where oste

21. Destilado da desodorização do oleo de soja como suplemento de vitamina E / Soybean oil deodorizer distillate as a vitamin E supplement
Increased use of industrial waste and byproducts fits the need of industry to comply with environmental rules. The substitution of natural products for artificial ingredients has gained worldwide attention in the food, pharmaceutical and other industries. These facts justify the study on the utilization of Soybean Oil Deodorizer Distillate (SODD) as tocopher

22. 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

23. Médula cervical como material para diagnóstico laboratorial da raiva. / Cervical spine as material for laboratory diagnosis of rabies.
Rabie is a neurotropic zoonosis infectum-contagious, whose persistence is mainly related to the street dogs, low immunity of the dog population and reduced adhesion to the laboratorial diagnosis, due to difficulty of collection and transport of the used material (brain). The cervical medulla can be considered the portion of the central nervous system of more

24. Biodistribuição do pertecnetato de sódio após cirurgia do Switch Duodenal
The biliopancretic diversion with duodenal switch is one of the mixing techniques used in the treatment of morbid obesity. The duodenal switch reduces the stomach capacity and leaves only 50-100 cm of small intestine for nutrition and absorption. The surgery produces hormonal, structural and biochemical changes, which can influence on the result of scintigra
