13. Implicações da programação pré-natal sobre o desempenho subsequente, características de carcaça e qualidade de carne em suínos
The objective of the present study was to investigate the influence of pre-natal programming on postnatal development, carcass traits and meat quality in pigs. Two hundred and eighty new-born male piglets (DanBred x PIC terminal line), born to 4th- 6th parity sows and in litters of 10 to 15 pigs, were identified as falling into two birth weight groups: high

14. Respostas de recuperação tecidual no cerebelo e córtex de filhotes expostos às crises convulsivas maternas / Response of tissue recovery in cerebellum and córtex of pups exposed to maternal seizures.
Objective: This study aimed to examine possible changes arising of hypoxic-ischemic insults in brain regions such as cerebellum and cortex at different stages of postnatal development of pups subjected to maternal seizures during intrauterine life. Methods: Wistar rats were subjected to the model of epilepsy induced by pilocarpine, mated and the seizure freq

15. Influence of intrauterine and extrauterine growth on neurodevelopmental outcome of monozygotic twins
There have been indications that intrauterine and early extrauterine growth can influence childhood mental and motor function. The objective of the present study was to evaluate the influence of intrauterine growth restriction and early extrauterine head growth on the neurodevelopmental outcome of monozygotic twins. Thirty-six monozygous twin pairs were eval

16. Expression of DLK1 and MEG3 genes in porcine tissues during postnatal development
The Drosophila-like homolog 1 (DLK1), a transmembrane signal protein similar to other members of the Notch/Delta/Serrate family, regulates the differentiation process in many types of mammalian cells. Callipyge sheep and DLK1 knockout mice are excellent examples of a fundamental role of the gene encoding DLK1 in muscle growth and fat deposition. DLK1 is loca

17. Effect of postnatal malnutrition on hyperoxia-induced newborn lung development
Several factors are associated with bronchopulmonary dysplasia. Among them, hyperoxia and lung immaturity are considered to be fundamental; however, the effect of malnutrition is unknown. Our objective was to evaluate the effects of 7 days of postnatal malnutrition and hyperoxia on lung weight, volume, water content, and pulmonary morphometry of premature ra

18. The role of diet, transforming growth factor alpha and epidermal growth factor receptor in the cell proliferation and differentiation during the postnatal development of the gastric epithelium of rats. / O papel do alimento, do fator de crescimento transformante alfa e do receptor do fator de crescimento epidermal na proliferação e diferenciação celular durante o desenvolvimento pós-natal do epitélio gástrico de ratos.
Early weaning (EW) causes changes in the gastric mucosa, including the increase in cell proliferation and Transforming Growth Factor (TGFa). In the present study, we evaluated the role of this peptide and its receptor EGFR in the control of the gastric growth. 15-d-old rats were divided into two groups: suckling (control) and EW, in which the pups were separ

19. Avaliação odontológica em pacientes com síndrome de Kabuki / Dental evaluation of Kabuki syndrome patients
INTODUCTION: Kabuki syndrome (KS) is a genetic disorder of unknown etiology characterized by moderate to severe mental retardation, postnatal growth deficiency, and peculiar face with long palpebral fissures and eversion of the lateral third of the lower eyelids, prominent ears and broad and depressed nasal tip. Oral manifestations are commonly observed in K

20. Ontogenia craniana comparada de Arctocephalus australis, Callorhinus ursinus e Otaria byronia (Otariidae: Pinnipedia)
The search for mechanisms that can generate major morphological changes has led to the study of ontogeny, in part because some kinds of modifications of ontogenies seem an excelent way to generate major phenotypic change. We focus here on Arctocephlaus australis, Callorhinus ursinus and Otaria byronia with the aim of contributing to the understanding of the

21. Avaliação clínico-laboratorial de pacientes com síndrome de Kabuki / Clinical and laboratorial evaluation of patients with Kabuki syndrome
INTRODUCTION: Kabuki syndrome (KS) is a genetic disease which cardinal manifestations are: facial dysmorfism, short stature of postnatal onset, skeletal abnormalities, mental retardation and abnormal dermatolyphics. Beside these manifestations, abnormalities of every organ system, has been described. The diagnosis is clinical. OBJECTIVES: The objective is to

22. In vitro study of sensitivity to IGF-1 of fibroblasts of children born small for gestational age without postnatal statural recovery / Estudo in vitro da sensibilidade ao IGF-1 de fibroblastos de crianças nascidas pequenas para a idade gestacional sem recuperação estatural pós-natal
Introdução: Crianças nascidas pequenas para a idade gestacional (PIG) apresentam maior risco de permanecerem com baixa estatura na vida adulta. Os fatores de crescimento insulino-símile tipo 1 e 2 (IGF-1 e IGF-2) são os principais fatores endócrinos determinantes do crescimento fetal. A maioria das ações conhecidas do IGF-1 e 2 é mediada via um rece

INTRODUCTION: The knowledge of the normal values of indices of Doppler velocimetry of the superior mesenteric artery in healthy premature neonates may help to prevent feeding intolerance situations and necrotizing enterocolitis. METHODS: In order to describe the indices for evaluation of Doppler velocimetry of the superior mesenteric artery in healthy premat

24. Pequeno para a idade gestacional : neurodesenvolvimento no primeiro ano de vida / Small-for-gestational age : neurodevelopment in the first year of age
Intrauterine malnutrition has been associated to long-term neurological morbidity and the small for gestational age infant is considered as a model for study this propose. The objective of this study was to evaluate the neurodevelopmental indicators according to Bayley Scales of Infant Development of full-term small-for-gestational age (SGA) infants compared
