Perspectives on fetal lung development

Lung, 1981
Lung development requires carefully regulated coordination of anatomic, physiologic, and biochemical processes. The result of these maturational events must be an organ having an adequate surface area, sufficient vascularization, and the metabolic capability to sustain oxygenation and ventilation during the neonatal period. Recent investigative efforts

Fetal Lung Development: Current Concepts

Pediatric Clinics of North America, 1973
Determination of the lecithin/sphingomyelin ratio in amniotic fluid and the newborn infant’s own tracheal fluid has proved of significant value in identifying the premature infant whose lungs have not yet matured to the point at which surface-active pulmonary lecithin will be synthesized rapidly enough after birth, and who are thus at risk for ...

Fetal Sexual Development

1984
To understand the pathophysiology of CAH, it is necessary to discuss normal sexual differentiation. According to the hypothesis developed by Jost (1971), normal differentiation of male genitalia is dependent on two functions of the fetal testes:

Monitoring fetal development with magnetocardiography

The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005
Fetal heart rate variability (fHRV) is useful for noninvasive assessment of the status of the autonomic nervous system of the developing fetus. In this pilot study we acquired fetal magnetocardiograms (fMCG) in a magnetically shielded environment.

Fetal chemoreception: a developing story

Reproduction, Fertility and Development, 1996
The central and peripheral chemoreceptors are critical to the efficient uptake and delivery of oxygen and the removal of carbon dioxide after birth. However, the importance and activity of fetal chemoreception has been questioned, since oxygen uptake and carbon dioxide removal are not regulated in the lungs in the fetus.

New developments in fetal echocardiography

Current Opinion in Cardiology, 1997
Fetal echocardiography has assumed an increasingly important role in the diagnosis of structural heart disease. Recently, the usefulness of this technique as a tool with which to observe the prenatal natural history of congenital heart disease has been appreciated.

Fetal Behavioral and Psychoneurological Development

2016
In this chapter, we focus on the assessment of the integrity and activity of the fetal central nervous system (CNS). Therefore it is necessary to understand normal behavior and which variables can be used to assess that (e.g., eye and body movements). Furthermore, one needs to understand the (neuro)developmental pathway during gestation, as a "younger"
