Renal responses to prolonged (48 h) hypoxemia without acidemia in the late-gestation ovine fetus.
The effect of sustained moderate hypoxia on renal blood flow and renal function was studied in the ovine fetus (123-129 days). The experiments consisted of 48 h of isocapnic hypoxia, not resulting in acidemia, but sufficient to produce redistribution of blood flow in favor of the brain at the expense of the carcass. Hypoxemia was induced by maternal nitrogen inhalation. Fetal arterial O2 satura...

متن کاملNeonatal survival after prolonged preterm premature rupture of membranes before 24 weeks of gestation.
OBJECTIVE To evaluate neonatal survival after prolonged preterm premature rupture of membranes (PROM) in the era of antenatal corticosteroids, surfactant, and inhaled nitric oxide. METHODS A single-center retrospective cohort study of neonates born from 2002-2011 after prolonged (1 week or more) preterm (less than 24 weeks of gestation) rupture of membranes was performed. The primary outcome ...
متن کاملProlonged maternal amino acid infusion in late-gestation pregnant sheep increases fetal amino acid oxidation.
Protein supplementation during human pregnancy does not improve fetal growth and may increase small-for-gestational-age birth rates and mortality. To define possible mechanisms, sheep with twin pregnancies were infused with amino acids (AA group, n = 7) or saline (C group, n = 4) for 4 days during late gestation. In the AA group, fetal plasma leucine, isoleucine, valine, and lysine concentratio...
متن کاملGestation
In the introductory chapter of this book it is explained that in the lower vertebrates there are lymphatic vessels but no lymph nodes; the lymphoid tissue in fish and amphibia is associated with myeloid tissue in such organs as the intestines, kidney, and liver. Lymph nodes first appear in certain birds, but it is only in mammals that they are invariably present. However, even in mammals, where...
