13. Vacinas de administração oral contra diarréia associada à Escherichia coli enteropatogênica baseada em linhagens geneticamente modificadas de Bacillus subtilis / Oral vaccines against diarrhea associated with enteropathogenic Escherichia coli strains based on genetically modified Bacillus subtilis strains
The objective of this work was the construction of genetically modified strains of B. subtilis able to express portions of intimin, the main component involved in colonization by enteropathogenic Escherichia coli strains (EPEC) as a strategy of oral vaccination against infectious diarrhea. The vaccines employed five regions of EPEC intimin and B. subtilis st

14. Roles of mitogen-activated protein kinases and angiotensin II in renal development
Experimental and clinical evidence suggests that angiotensin II (AII) participates in renal development. Renal AII content is several-fold higher in newborn rats and mice than in adult animals. AII receptors are also expressed in higher amounts in the kidneys of newborn rats. The kidneys of fetuses whose mother received a type 1 AII receptor (AT1) antagonist

15. Determinação de rotavírus em suínos em uma granja do Rio Grande do Sul
Diarrhea, in newborn animals, is a morbid disease that exists worldwide; rotaviruses have been considered one of the main causes of gastroenteritis of viral origin, especially in countries where pig farming is intensively explored. The objective of this study was to extend the knowledge about the incidence of rotavirus in pigs, using the latex agglutination

16. The use of cardiotocography as a method of diagnosis of the occurrence of fetal distress (fetal hypoxia) during intrauterine life in fetuses of Nellore generated through the technique of somatic adult cell nuclear transfer - Cloning / O uso da cardiotocografia como método de diagnóstico da ocorrência de sofrimento fetal (hipóxia fetal) durante a vida intrauterina de fetos da raça Nelore originados por meio da técnica de transferência nuclear de células somáticas adultas - Clonagem
This research had the purpose to standardize the technique of cardiotocography to be used to assess the presence of hypoxia / fetal distress during intrauterine life, trying to establish from the 7th month of pregnancy the normal range of fetal heart rate in healthy fetuses and from artificial insemination and cloning to evaluate the influence of the paramet

17. 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

18. Effect of obesity on rat reproduction and on the development of their adult offspring
The aim of the present study was to assess the reproductive parameters of obese Wistar rats and to determine the frequency of their obese adult offspring. Neonatal rats were divided into two groups: F1 generation, induced to obesity by monosodium glutamate (MSG; F1MSG, N = 30), and rats given saline (F1CON, N = 13). At 90 days of age all animals were mated,

19. Immunohistochemical studies of stellate cells in experimental cholestasis in newborn and adult rats
BACKGROUND AND AIMS: Although there is much known about liver diseases, some aspects remain unclear, such as the nature of the differences between the diseases observed in newborn infants and those in adults. For example, how do newborns respond to duct epithelial cell injury? Do the stellate cells in newborns respond similarly to those in adults during bili

20. Miíases Umbilicais em Bezerros Nelore Recém-Nascidos: Predisposição de Dois Cruzamentos Raciais Criados no Sistema de Manejo Voisin no Rio de Janeiro e Avaliação de Medidas Profiláticas em Criação Extensiva no Pantanal Sul-Mato-Grossense. / Umbilical Myiasis in Nelore Newborn Calves: Predisposition of Two Racial Crossings Raised in a Voisin System in Rio de Janeiro and Evaluation of Prophylactic Measures in Extensive Cattle Raising in the Pantanal Sul-Mato-Grossense.
The research was done in two distinct properties of beef cattle raising. The first part of the experiment was executed in Santo Antônio Farm, located in Miguel Pereira city, Rio de Janeiro State, with the objective of evaluating the susceptibility and the prevalence of umbilical myiasis in the newborn calves, resultant of the crossings between Brahma pure b

22. Petroleum ether extract of Cissus quadrangularis (LINN) stimulates the growth of fetal bone during intra uterine developmental period: a morphometric analysis
OBJECTIVE: The aim of the present study was to analyze the effect Cissus quadrangularis plant petroleum ether extract on the development of long bones during the intra-uterine developmental stage in rats. METHODS: Pregnant rats (n=12) were randomly assigned into either a control group (n=6) or a Cissus quadrangularis treatment (n=6) group. Pregnant rats in t

24. Experimental models of liver regeneration in growing animals. Histological and molecular studies, and evaluation of the effects of immunosuppressants / Modelos de regeneração hepática em animais em crescimento: estudos histológicos, moleculares e avaliação de efeitos de imunossupressores
INTRODUCTION: Partial liver transplantation has been performed in children with increasing frequency, and this emphasizes the importance of the studies of hepatic regeneration and the effects of immunosuppressive drugs on this phenomenon. Liver regeneration is controlled by the balance between cell proliferation and apoptosis (defined as a programmed cell de
