Fetal oxygen delivery and consumption and blood gases in relation to gestational age [PDF]
arXiv, 2021 Fetal oxygen delivery and consumption and blood gases in relation to gestational age. Oxygen crosses the placenta by diffusion and placental permeability to O$_2$ is high. Thus, the fetus receives adequate amounts, but vascular Po$_2$ is much lower than after birth. Studies of sustained fetal hypoxemia and acute 40-45% hemorrhage show that hypoxemia is

Risks of small-for-gestational-age births in immigrants: A nationwide epidemiological study in Sweden. [PDF]
, 2012 Aim: To examine if there is an association between country of birth in parents and small-for-gestational-age (defined as a birthweight of more than two standard deviations (SDs) below the mean) in first singletons births. Methods: In this follow-up study,

Generating functionals and Gaussian approximations for interruptible delay reactions [PDF]
, 2015 We develop a generating functional description of the dynamics of non-Markovian individual-based systems, in which delay reactions can be terminated before completion. This generalises previous work in which a path-integral approach was applied to dynamics in which delay reactions complete with certainty.

A Personalized Fluid-structure Interaction Modeling Paradigm for Aorta in Human Fetuses [PDF]
arXiv, 2023 Fluid-structure interaction (FSI) modeling, a technique widely used to enhance imaging modalities for adult and pediatric heart diseases, has been underutilized in the context of fetal circulation because of limited data on flow conditions and material properties.

A method to investigate muscle target‐specific transcriptional signatures of single motor neurons
Developmental Dynamics, Volume 252, Issue 1, Page 208-219, January 2023., 2023 Abstract Background Motor neurons in the vertebrate spinal cord have long served as a paradigm to study the transcriptional logic of cell type specification and differentiation. At limb levels, pool‐specific transcriptional signatures first restrict innervation to only one particular muscle in the periphery, and get refined, once muscle connection has ...

Prediction of small-for-gestational age by fetal growth rate according to gestational age
PLOS ONE, 2019 Small-for-gestational age (SGA) infants should be identified before birth because of an increased risk of adverse perinatal outcomes. The objective of this study was to assess the impact of fetal growth rate by gestational age on the prediction of SGA and to identify the optimal time to initiate intensive fetal monitoring to detect SGA in low-risk ...

Are preeclampsia and small for gestational age baby could be predicted by placental location? [PDF]
, 2017 Objective: Preeclampsia is one of the major cause of maternal and perinatal mortality and morbidity. The pathophysiology is complex and involves multiple organs. The purpose of this study was to find out whether the placental laterality as a predictor of

Characterisation of placental malaria in olive baboons (Papio anubis) infected with Plasmodium knowlesi H strain [PDF]
Int. J. Integ. Biol: Year 2012 Volume 9, Issue No. 2: 54 - 58, 2012 Pregnant women have increased susceptibility to malaria infection. In these women, malaria parasites are frequently found sequestered in the placental intervillous spaces, a condition referred to as placental malaria (PM). Placental malaria threatens the health of the mother and the child's life by causing still births and reduction in gestational age.
