25. Incorporação de ácidos graxos trans e seus efeitos em diferentes fases do crescimento de ratos / Trans fatty acids incorporation and its effects in different phases of rat growth
Clinical, epidemiological and experimental evidences certify the role of trans fatty acids in the genesis of non-transmissible chronic diseases. The atherogenic effects of trans fatty acids produced by industrialization process are well known in adult subjects. However, little is known about its effects on maternal-infantile and infantile-juvenile population

26. Efeitos da adição de polietilenoglicol ao surfactante exógeno no tratamento da síndrome de aspiração de mecônio em coelhos recém-nascidos / Effects of polyethylene glycol added to exogenous surfactant for meconium aspiration syndrome treatment in newborn rabbits
Meconium is known to be a potent inactivator of pulmonary surfactant, and exogenous surfactant treatment for meconium aspiration syndrome failed to decrease mortality. A number of studies have shown, in vitro, that the addition of polymers such as polyethylene glycol (PEG) to the surfactant maintains good surface activity in the presence of meconium. In the

27. Morphoquantitative aspects of undernourishment-induced neuroplasticity in the rat´s celiac ganglion neurons. / Aspectos morfoquantitativos da neuroplasticidade induzida por desnutrição no gânglio celíaco de ratos
The celiac ganglion belongs to the celiac plexus which consists of a net of nerves and supportive tissues. The celiac ganglia, even, are alonged and locate along the caudal face of the origin of the celiac artery. On the left side the ganglion is linked by an interganglionar branch. It is intimately in contact with the surface of the aorta. The autonomous in

28. NUDEL-OLIGOPEPTIDASE: ANÁLISE DA DISTRIBUIÇÃO DO RNAm NO SNC DE RATOS NEONATOS E ADULTOS E CARACTERIZAÇÃO DO RESÍDUO CRÍTICO PARA A ATIVIDADE CATALÍTICA. / NUDEL-oligopeptidase: analysis of mRNA distribution in the central nervous system (CNS) of newborn and adult rats, and characterization of the amino acid residue critical for the catalytic activity.
Thirty years ago the first endooligopeptidases were described, and named Endo A (EOPA) and Endo B. EOPA was later characterized as a thiol-activated peptidase showing specificity for substrates comprising 7 to 13 amino acid residues. In 2000, studying the molecular mechanisms of the brain disorder lissencephaly, three independent groups isolated a protein na

29. Parameters of security and functionality of the Bifidobacterium isolated from newborn, with potential of use as probiotics in human milk banks / Parâmetros de segurança e funcionalidade de bactérias bífidas isoladas de recém-nascidos, com indicação de uso como probiótico em bancos de leite humano
The objective of this study was to evaluate some parameters of security and functionality currently recommended for validation of probiotics. The parameters evaluated were antimicrobial susceptibility, antagonism to the growth of pathogens, oral chronic toxicity and bacterial translocation of new lineages of Bifidobacterium breve isolated from newborn, with

30. Caracterização de um novo fator de colonização (FC O25) de Escherichia coli isoladas de colibacilose neonatal bovina / Characterization of a new colonization (CF O25) of Escherichia coli isolated from neonatal bovine colibacillosis
Infections from Escherichia coli are frequent in domestic animals, affecting mainly newborn animals in the post weaning period, being thus responsible for important economic losses in the cattle, porcine and lamb herds. The establishment of the bacterium in the host is made by colonization and it is a process mediated by proteins called adhesins that are dis

31. Ectopic development of skeletal muscle induced by subcutaneous transplant of rat satellite cells
The present study analyzes the ectopic development of the rat skeletal muscle originated from transplanted satellite cells. Satellite cells (10(6) cells) obtained from hindlimb muscles of newborn female 2BAW Wistar rats were injected subcutaneously into the dorsal area of adult male rats. After 3, 7, and 14 days, the transplanted tissues (N = 4-5) were proce

32. Alterações hematológicas e humorais de eqüinos expostos à infecção por Babesia equi, na região sul do Rio Grande do Sul / Humoral and hematological changes in equines exposed to infection by Babesia equi, in the southern regions of Rio Grande do Sul state, Brazil
The equine babesiosis is one of the most important parasitic disease of the equines, it causes great damage to animal health. The disease is a haemoparasitosis caused by Babesia equi. Through infecting and destroying red blood cells, it can compromise the equine function, leading to loss of vitality and decrease in the performance of infected animals. The pu

33. O gene da miogenina: sequenciamento em suínos e análise filogenética / The myogenin gene: sequencing in swine and phylogenetic analysis
Meat production capacity is related to muscle fibers number show in newborn animals. The muscle fibers are formed in the myogenesis that takes place during the embryonic development, an event that is controlled in part by the MyoD gene family. The Myogenin gene is a member of this family and rules the expression of muscle specific genes. It has an important

34. Insulin-like growth factor-i during the formation and transfer of passive immunity to newborn calves. / Fator de crescimento semelhante à insulina-I no período de formação e transferência de imunidade passiva para bezerros recém-nascidos.
Forty-two Holstein cows, in gestation and multiparous, and their newborn calves were used to evaluate if insulin-like growth factor-I (IGF-I) in colostrum and subsequent mammary secretions could be influenced by changes in blood serum IGF-I and compare its temporal changes with the serum immunoglobulin G (IgG) in pre-partum period, as well as the temporal ch

35. Development of structural heterogeneity of mitochondria in mouse hepatocytes.
The volume and shape (the axial ratio:length/diameter) of mitochondria in periportal and perihepatic hepatocytes from newborn, 5 days old, 10 days old and adult male ddY mice were analysed by quantitative electron microscopy. In newborn animals, the volume and relative histogram of the axial ratio were not significantly different between periportal and perih

36. VEGF increases engraftment of bone marrow-derived endothelial progenitor cells (EPCs) into vasculature of newborn murine recipients
Recent evidence suggests that bone marrow-derived angioblasts or endothelial progenitor cells circulate in peripheral blood and can incorporate at sites of pathologic neovascularization or during the ovarian cycle. However, the incorporation of endothelial progenitor cells into vessels of nonischemic tissues in adult animals has not been observed. We hypothe
