25. Interventions in the neonatal environment in rats and their relationship to behavior in adulthood and maternal behavior
The objective of this study was to assess the role of environmental/nest components and maternal behavior after several neonatal interventions on subsequent behavioral responses. Male Wistar rats were subjected to different neonatal interventions and were later evaluated for innate fear-like behavior in adulthood. The experimental groups included nonhandled

26. Aversive stimulation during the stress-hyporesponsive period does not affect the number of corticotroph cells in neonatal male rats
Immunohistochemistry was used to evaluate the effects of neonatal handling and aversive stimulation during the first 10 days of life on the number of corticotrophs in the anterior lobe of the pituitary of 11-dayold male Wistar rats. Since adult rats handled during infancy respond with reduced corticosterone secretion in response to stressors and with less be

27. Neonatal handling and the expression of immunoreactivity to tyrosine hydroxylase in the hypothalamus of adult male rats
Neonatal handling has long-lasting effects on behavior and stress reactivity. The purpose of the present study was to investigate the effect of neonatal handling on the number of dopaminergic neurons in the hypothalamic nuclei of adult male rats as part of a series of studies that could explain the long-lasting effects of neonatal stimulation. Two groups of

28. Desenvolvimento da próstata masculina e feminina do gerbilo da Mongólia submetido à exposição no período embriofetal e pós-natal de etinilestradiol / Development of male and female prostate of the Mongolian gerbil submitted to the exposure embryofetal period and postnatal ethinylestradiol
In males, prostatic morphogenesis is an event controlled by androgens, which act directly via paracrine factors secreted by the mesenchyme. In females, the embryological development of the prostate appears to occur in environment low levels of steroid hormones, but the presence of these hormones in the adult life induces differentiation and secretory activit

29. Effects of maternal deprivation for the anxious-like behavior: involvement of the hypothalamic-pituitary-adrenal system and neurotransmission GABAaérgico / Consequências da privação materna para o comportamento tipo-ansioso: participação do eixo hipotálamo-pituitária-adrenal e do sistema de neurotransmissão GABAaérgico.
Adverse events in childhood have been associated to the development of psychopathologies, such as depression and anxiety disorders. In rats, stressful events during neonatal period, like 24h Maternal Deprivation (MD), may be an interesting tool to understand how stress during early life leads to changes in behavior and stress response in adulthood. According

30. Tratamento neonatal com agonista 5-HT1A: repercussÃes sobre o desenvolvimento da atividade locomotora em ratos
Locomotion is an important function to living beings. Environmental changes that occur during the critical period of development can promote changes in the development of locomotor activity, bringing impairment for the individual. Works using automatic analysis of behavior are of great importance for the study of locomotion. Among the systems that can influe

31. Communicative and psycholinguistic abilities in children with phenylketonuria and congenital hypothyroidism
The Neonatal Screening for Inborn Errors of Metabolism of the Association of Parents and Friends of Special Needs Individuals (APAE) - Bauru, Brazil, was implanted and accredited by the Brazilian Ministry of Health in 1998. It covers about 286 cities of the Bauru region and 420 collection spots. Their activities include screening, diagnosis, treatment and as

32. A sobrecarga na família de crianças com paralisia cerebral / Overload on the families of children with cerebral palsy.
Cerebral Palsy (CP) is an alteration to ones posture and movement. It is permanent, but not unchangeable, and results from an unprogressive brain disorder, which can be genetic or due to events occurred during pregnancy, delivery, in the neonatal period, or during the first two years of life. This condition causes impairment to ones motor activities, usually

33. Estudo da maturação da resposta vascular da artéria mesentérica superior em recém-nascidos prematuros através do dopplerfluxometria / Evolution of superior mesenteric artery blood flow by means of doppler velocimetry in health premature neonates
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

34. Biochemical, molecular and behavioral alterations induced by neonatal hypoxia in mice. / Alterações bioquímicas, moleculares e comportamentais induzidas por hipóxia neonatal em camundongos
Introduction: Neonatal hypoxia-ischemia is one of the most significant factors that can lead to death in newborns. It has been linked with pathology in adult life, such as schizophrenia. Objectives: The aim of this work was to investigate long-term effects of neonatal hypoxia on body weight, behavior, antioxidant defense status, factors related to homocystei

O presente estudo investigou o perfil comportamental de ovinos entre o parto e a primeira mamada dos neonatos e sua influência sobre a sobrevivência e peso ao desmame dos cordeiros. O experimento foi conduzido em uma criação comercial de sistema intensivo, ao longo de três estações de parição, entre junho e novembro de 2006. Foram acompanhadas 216 o

36. Imprinting estrogenico : efeito sobre a expressão do receptor de androgeno no hipotalamo de ratos Wistar / Effects of estrogenic imprinting on the androgen receptor expression in the hypothalamus of Wistar rats
In male rats, complete reproductive function is critically dependent on adequate estrogen action at different levels of the hypothalamic-pituitary-gonadal axis. The administration of high doses during the period of sexual differentiation results in irreversible alterati ns in the male reproductive system. In brief, the estrogens have anti-androgenic effects
