1. Fetal death: obstetric, placental and fetal necroscopic factors
RESUMO Introdução: Óbito fetal se define como morte do produto da concepção independente do tempo da gestação. Objetivos: O objetivo deste estudo foi investigar os fatores de risco maternos (obstétricos e placentários) e os achados de necropsia associados ao óbito fetal a partir de dados obtidos no Serviço de Verificação de Óbito (SVO) de Flo

2. Doppler venoso fetal na insuficiência placentária: relação com o pH no nascimento / Fetal venous Doppler in pregnancies with placental dysfunction: correlation with pH at birth
OBJECTIVE: This study, conducted in high-risk pregnancies with placental insufficiency, aims to avaliate blood flow in the fetal left portal vein (LPV), umbilical vein (UV) and ductus venosus (DV), and establish which parameters are associated with acidemia at birth. METHOD: A prospective research involving 58 pregnant women, classified according to the pres

3. Alterações comportamentais e a análise do estresse oxidativo na idade adulta de animais expostos a hipóxia pré-natal
A Hipóxia-Isquêmica (HI) pré-natal é caracterizada por uma redução no aporte de oxigênio e nutrientes para o feto durante o período gestacional, que pode acarretar, a longo prazo, em dificuldade de concentração e aprendizagem, hiperatividade e déficit de memória. Esses prejuízos podem persistir ou se agravar até a idade adulta, levando ainda ao

4. Efeito do exercício físico durante a gravidez sobre o fluxo sanguíneo feto-placentário e o crescimento fetal : ensaio controlado e aleatorizado / Effect of exercise during pregnancy on the blood flow fetal-placental and fetal growth : randomized controlled trials
Introduction: Fetal growth has always been one of the major concerns regarding the practice of exercise during pregnancy, with discussions on whether the redistribution of fetoplacental blood flow during physical exercise and the bypass of blood from the viscera to the muscles could lead to transitory fetal hypoxia. Objective: To study the. E effect of super

5. Efeito da hipóxia e das deleções dos genes IL15 e PLP-A na vascularização do útero gestante mediada pelas células uNK / Effect of hypoxia and depletion of IL15 and PLP-A genes in the vasculature of pregnant uterus mediated by uNK cells
Um processo de remodelação progressiva da vascularização uterina precede a placentação em humanos e roedores para prover o suprimento sanguíneo adequado na interface materno-fetal, tendo as células NK um papel modulador através da produção de citocinas como o IFN gama , fatores de crescimento como o VEGF e radicais livres como o óxido nítrico (N

6. The use of cardiotocography as a method of diagnosis of the occurrence of fetal distress (fetal hypoxia) during intrauterine life in fetuses of Nellore generated through the technique of somatic adult cell nuclear transfer - Cloning / O uso da cardiotocografia como método de diagnóstico da ocorrência de sofrimento fetal (hipóxia fetal) durante a vida intrauterina de fetos da raça Nelore originados por meio da técnica de transferência nuclear de células somáticas adultas - Clonagem
This research had the purpose to standardize the technique of cardiotocography to be used to assess the presence of hypoxia / fetal distress during intrauterine life, trying to establish from the 7th month of pregnancy the normal range of fetal heart rate in healthy fetuses and from artificial insemination and cloning to evaluate the influence of the paramet

7. Analise de possiveis mecanismos e consequencias funcionais da expressão de galectina-3 em celulas de glioma expostas a condições hipoxicas / Analysis of possible mechanisms and functional consequences of galectin-3 expression in glioma cells exposed to hypoxia
Gliomas are primary Central Nervous System tumors. Among them, glioblastomas are the most common clinical forms and have the worst prognosis. In an attempt to understand glioma biology, the NG97 cell line was established. This cell line presents glioblastoma s characteristics, showing nuclear atipia and high growth rate. Recently, it was discovered that this

8. 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

9. Myocardial infarction and subsequent pregnancy
We report the case of a 40-year-old woman with 2 previous myocardial infarctions, revascularization surgery, and an ongoing pregnancy complicated with preeclampsia and fetal hypoxia. Her follow-up performed by a multidisciplinary team made possible the birth through cesarean section of a premature infant of the female sex with a very low birth weight, but wi

10. Adenosine mediates metabolic and cardiovascular responses to hypoxia in fetal sheep.
1. In seven unanaesthetized fetal sheep (> 80% term), isocapnic hypoxia (arterial partial pressure of O2, Pa,O2, approximately 15 mmHg) was induced for 1 h by lowering maternal inspired PO2. Fetal hypoxia was also produced during intra-arterial administration of the adenosine receptor antagonist 8-(p-sulphophenyl)-theophylline (8-SPT). The fetal 8-SPT infusi

11. Transabdominal near infrared oximetry of hypoxic stress in fetal sheep brain in utero
The feasibility of transabdominal near-infrared (NIR) spectroscopy for detecting and quantifying fetal hypoxia in utero is demonstrated in a pregnant ewe model. A frequency domain NIR spectroscopy probe, consisting of two detectors and six sources operating at three wavelengths (675, 786, and 830 nm), was placed on the maternal abdomen directly above the fet

12. Effects of chronic hypoxia on soluble guanylate cyclase activity in fetal and adult ovine cerebral arteries
A broad variety of evidence obtained largely in pulmonary vasculature suggests that chronic hypoxia modulates vasoreactivity to nitric oxide (NO). The present study explores the general hypothesis that chronic hypoxia also modulates cerebrovascular reactivity to NO, and does so by modulating the activity of soluble guanylate cyclase (sGC), the primary target
