13. Effects of nitric oxide on magnocellular neurons of the supraoptic nucleus involve multiple mechanisms
Physiological evidence indicates that the supraoptic nucleus (SON) is an important region for integrating information related to homeostasis of body fluids. Located bilaterally to the optic chiasm, this nucleus is composed of magnocellular neurosecretory cells (MNCs) responsible for the synthesis and release of vasopressin and oxytocin to the neurohypophysis

14. Role of α2-adrenoceptors in the lateral parabrachial nucleus in the control of body fluid homeostasis
Central α2-adrenoceptors and the pontine lateral parabrachial nucleus (LPBN) are involved in the control of sodium and water intake. Bilateral injections of moxonidine (α2-adrenergic/imidazoline receptor agonist) or noradrenaline into the LPBN strongly increases 0.3 M NaCl intake induced by a combined treatment of furosemide plus captopril. Injection of mo

15. Immersion in water in labour and birth
BACKGROUND: Enthusiasts suggest that labouring in water and waterbirth increase maternal relaxation, reduce analgesia requirements and promote a midwifery model of care. Critics cite the risk of neonatal water inhalation and maternal/neonatal infection. OBJECTIVES: To assess the evidence from randomised controlled trials about immersion in water during

16. AÇÃO CENTRAL DA OCITOCINA NO CONTROLE DA INGESTÃO ALIMENTAR: influência do ciclo estral. / CENTRAL ACTION OF OXYTOCIN ON THE CONTROL OF FOOD INTAKE: influence of the estrous cycle.
In addition to stimulation of uterine contraction and milk ejection, oxytocin (OT) acts on neural circuits that control food intake. This study aimed to investigate the gonadal modulation of ocitocinergic control on food ingestion. Female Wistar rats with at least three regular cycles were monitored for 15 days and underwent implantation of cannula into the

17. Estresse pré-natal e suas repercussões sobre o cuidado maternal e comportamento de ratos a curto e a longo prazo
In humans and rodents, stress during pregnancy has produced offspring with high levels of anxiety, impaired learning and memory, changes in maternal care and social behavior deficits. Most prenatal stress protocols have attributed their results to the vulnerability of the intrauterine period. However, studies show that the consequences caused by this action

18. Avaliação da eletroestimulação nervosa transcutânea para alívio da dor de contração uterina pós-parto durante a amamentação: ensaio clínico randomizado / Assessment of transcutaneous electrical nerve stimulation to relieve the painful postpartum uterine contractions during breastfeeding: a randomized clinical trial
During breastfeeding occurs the release of oxytocin for milk ejection, that cause uterine contractions associated with painful process. The transcutaneous electrical nerve stimulation (TENS) is a physical therapy resource, which aims to pain relief. The main objective of this study was to evaluate the effectiveness of TENS to relief of painful uterine contra

19. Efeitos sequenciais do treinamento físico sobre a plasticidade de vias ocitocinérgicas centrais em ratos normotensos e hipertensos. / Sequential effect of aerobic training on the plasticity of central oxytocinergic system in normotensive and hypertensive rats.
Nós investigamos o efeito sequencial do treinamento aerório (T) nas vias ocitocinérgicas (OTérgicas) em áreas centrais autonômicas, utilizando o fator neurotrófico derivado do cérebro (BDNF) como um indicador de plasticidade neuronal. Ratos normotensos (WKY) e espontaneamente hipertensos (SHR) foram submetidos a T ou sedentarismo (S) por 8 semanas. T

20. Dosagens sanguíneas de ocitocina por enzimoimunoensaio após diferentes regimes de infusão de ocitocina em gestantes submetidas à cesariana eletiva com raquianestesia / Oxytocin blood levels following different regimens of oxytocin administration in elective cesarean delivery
INTRODUÇÃO: Apesar de ser a droga de primeira escolha na prevenção da hemorragia pós-parto, o uso da ocitocina em cesarianas permanece empírico. O objetivo deste estudo foi dosar a ocitocina sérica após a administração profilática de diferentes regimes de ocitocina em pacientes submetidas à cesariana eletiva. MÉTODOS: 30 pacientes que se apresen

21. Effect of social instigation and aggressive behavior on hormone levels of lactating dams and adult male Wistar rats
Among rodents, maternal aggression in the postpartum period represents a species-typical adaptation, but when aggressive behavior increases beyond this adaptive level, it can represent a model of excessive aggression. This study assessed the neuroendocrine response of lactating rats and socially instigated male rats. The aim of the present study was to asses

22. Efeitos a longo prazo de diferentes separações dos filhotes no período neonatal sobre as genitoras
Esse estudo foi realizado para verificar se a exposição a separações repetidas (por diferentes intervalos de tempo) de mães dos seus filhotes no período neonatal poderiam ser classificadas como indutoras de um estado do tipo deprimido em genitoras. Sessenta ratas Wistar prenhes foram divididas em 3 grupos: controle, separação por 10 minutos e separa�

23. Clinical evaluation of the flotrac/vigileo™ system for continuous cardiac output monitoring in patients undergoing regional anesthesia for elective cesarean section: a pilot study
BACKGROUND: Spinal anesthesia for cesarean delivery may cause severe maternal hypotension and a decrease in cardiac output. Compared to assessment of cardiac output via a pulmonary artery catheter, the FloTrac/Vigileo™ system may offer a less invasive technique. The aim of this study was to evaluate cardiac output and other hemodynamic measurements made us

24. Prevalência e fatores associados de incontinência urinária autorreferida no pós-parto / Prevalence and associated factors of urinary incontinence self-reported in the postpartum period
Urinary incontinence (UI) is defined as any involuntary loss of urine, being a social and hygiene problem. In Brazil, the literature about the urinary incontinence after childbirth is incipient. UI is a morbid little explored by health professionals, making it difficult to identify the woman who has a complication. The aim of this study was to assess the pre
