1. Reversible cerebral vasoconstriction syndrome a rare cause of post-partum headache: an anesthetic overview
Resumo A síndrome de vasoconstrição cerebral reversível é uma doença cerebrovascular que leva à constrição e dilatação arterial multifocal. A síndrome de vasoconstrição cerebral reversível é possivelmente causada pela desregulação transitória do tônus vascular cerebral. Relatamos um caso raro de uma paciente com queixa principal de cefale

2. Perinatal effects of scorpion venoms: maternal and offspring development
Abstract Scorpion envenomation is a public health problem, especially in tropical and subtropical countries. Considering the high incidence of scorpionism in some areas, pregnant women and nursing mothers may be possible victims. Scorpion stings alter the release of neurotransmitters and some cytokines. These mediators act as organizers and programmers in th

4. 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

5. 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

6. The effect of combined spinal-epidural labor analgesia on uterine tone and fetal heart rate: randomized comparison with epidural analgesia / Efeito da analgesia obstétrica combinada raqui-peridural no tônus uterino e na freqüência cardíaca fetal: ensaio clínico randomizado comparativo com a analgesia peridural
In order to investigate the association between uterine tone elevation and fetal heart rate (FHR) abnormalities following labor analgesia - mainly with combined spinal-epidural (CSE) technique - a prospective double-blinded randomized study was conducted with seventy seven parturients who requested labor analgesia. Study group (41 cases) received CSE with su

7. Assistência clínica materna e neonatal às diferentes condições obstétricas em bovinos da raça Holandesa / Maternal and neonatal clinical assistance under distinct obstetrical conditions in Holstein cattle
The novel reproductive biotechnologies (ET, IVF and Cloning) require more accurate control of pregnancy and parturition, due to obstetrical problems as a result of the large offspring syndrome or reduced calf vitality associated with placental anomalies. Hence, the reduction in neonatal mortality is justifiable as research in this area progresses, aiming mat

8. Scorpion envenomation symptoms in pregnant women
Scorpion envenomation is common in many countries; however, its effects on pregnancy are still unclear. In the present paper, we described the effects of scorpion envenomation on pregnant patients. A retrospective study was carried out considering the clinical and laboratory exams of patients admitted to the emergency room of Habib Bourguiba Hospital, Sfax,

9. Evaluation of uterine electric activity in pregnant and non pregnant Wistar rats induced by electroacupuncture and the influence of central nervous system and biologically closed electric circuits / Avaliação da atividade elétrica uterino em ratas Wistar prenhes e não prenhes induzida por eletroacupuntura e da influência do sistema nervoso central e dos circuitos elétricos biologicamente fechados
O objetivo desse trabalho foi a avaliação da atividade elétrica uterina em ratas Wistar prenhes antes e após a eletroacupuntura e a influência do sistema nervoso central e dos circuitos elétricos biologicamente fechados. A avaliação da atividade elétrica cerebral e uterina foi realizada por meio de experimentos crônicos (n=16, 8 prenhes e 8 não pr

10. Occurrence of intracellular pH transients during spontaneous contractions in rat uterine smooth muscle.
1. Intracellular pH (pHi) and contraction have been measured simultaneously in isolated longitudinal rat myometrium. Tissue was loaded with the pH-sensitive fluorophore carboxy-SNARF and superfused with oxygenated, buffered salt solution at 37 degrees C and pH 7.4. 2. Small (0.04 pH unit) transient intracellular acidifications followed each spontaneous uteri

11. An in vivo study of the effects of ischaemia on uterine contraction, intracellular pH and metabolites in the rat.
There are no data concerning the functional or metabolic effects of hypoxia in vivo in smooth muscle. We have therefore used 31P-NMR spectroscopy and intra-uterine pressure measurements to examine simultaneously, in vivo, the effect of ischaemia on uterine metabolites, intracellular pH (pHi) and force. A 1-2 cm portion of uterus from day 1 postpartum anaesth

12. Kallikrein-induced uterine contraction independent of kinin formation.
Responses of smooth muscle to kallikreins (EC 3.4.21.8) are generally considered to result from kinin formation. This premise was reexamined with the isolated rat uterus. Rat urinary kallikrein or bradykinin produced dose-dependent contractions of rat uterus but kallikrein was 5-fold more potent than bradykinin. Kallikrein caused an immediate series of rhyth
