UNLABELLED Fetal behavior is defined as any fetal action seen by the mother or fetus diagnosed by objective methods such as cardiotocography (CTG) or ultrasound. Analysis of the dynamics of the fetal behavior with morphological studies has lead to the conclusion that fetal behavior patterns are directly reflecting development and maturation of the central nervous system. The assessment of fetal...

OBJECTIVE The purpose of this study was to evaluate the effects of maternal-fetal genetic histocompatibility and the association of that condition with maternal undernutrition regarding fetal growth and litter size. STUDY DESIGN Fetuses that were either syngeneic or allogeneic with the mothers were bred, using mice of well-defined syngeneic strains (A/J and Balb/c). Pregnant mice were fed usi...

chimpanzee, 34–35 weeks) [4], human neonates do have larger brains than chimpanzee neonates [2]. It has been suggested that the extraordinary brain enlargement in humans is due to unique features in the human pattern of brain development during both the prenatal and postnatal periods [1,2]. It has been argued that all primates conform to a 12% ratio of brain mass to body mass from the fetal per...

OBJECTIVE Changes in blood oxygen level dependent (BOLD) magnetic resonance imaging (MRI) signal are closely related to changes in fetal oxygenation. In this study, we aimed to investigate the changes in human fetal oxygenation during maternal hyperoxia by using the non-invasive BOLD MRI technique. METHOD Eight healthy pregnant women in gestational week 28 to 34 were included. With the use of...

OBJECTIVE To evaluate whether a full-coverage fetal-maternal scanner can noninvasively monitor ongoing electrophysiological activity of maternal and fetal organs. METHODS A simulation study was carried out for a scanner with an array of magnetic field sensors placed all around the torso from the chest to the hip within a horizontal magnetic shielding enclosure. The magnetic fields from intern...

Lapidot Deoartment of Organic Chemistrv, The Weizmann Institute of Science, Rehovot 76100, Israel L -u-~ , Introduction metabolites, including lactate, and the amino acids, were not altered during insulin-induced hypoglycemia, the labeling patterns of glutamate, glutamine, lactate and alanine were, in some cases, quite different...

BACKGROUND Severe fetal acidemia during labour with arterial pH below 7.00 is associated with increased risk of hypoxic-ischemic brain injury. Electronic fetal heart rate (FHR) monitoring, the mainstay of intrapartum surveillance, has poor specificity for detecting fetal acidemia. We studied brain electrical activity measured with electrocorticogram (ECOG) in the near term ovine fetus subjected...

introduction: survivin, an inhibitor of apoptosis (iap) containing one baculoviral iap repeat (bir) domain, has been reported to be able to regulate both cellular proliferation and apoptotic cell death. in the present study, we evaluated the differential expression of different variants of survivin during prenatal and postnatal development of brain in mice. material and methods a total of 27 nm...
