Glucocorticoids and fetal lung development

Journal of Steroid Biochemistry, 1977
Abstract Acceleration of fetal lung development by administration of glucocorticoid hormones has been demonstrated in a number of mammalian species. Dexamethasone 10 −5 M significantly depressed protein content per explant in the presence and absence of insulin.

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 Prostate Growth and Development

Pediatric Pathology, 1990
Normal fetal and newborn prostates were studied to evaluate growth patterns, histogenesis, and secretory activity. Whole cross-sectioned prostates harvested from 107 necropsies of fetuses and newborns ages 20 weeks gestation to 1 month of age were used.

The Development of Human Fetal Hearing

Science, 1983
Blink-startle responses to vibroacoustic stimulation were monitored ultrasonically in human fetuses of known gestational age. Responses were first elicited between 24 and 25 weeks of gestational age and were present consistently after 28 weeks.

Fetal Development of the Urethral Sphincter

European Journal of Pediatric Surgery, 1992
A morphological study was carried out on 25 human embryos (3-60 mm CR) and 20 human fetuses (15-40 weeks). The anatomical analysis was completed by immunocytochemical studies of different markers of muscle differentiation (vimentin, desmin, titin and isoforms of the myosin heavy chains).

Anatomical development of the fetal uterus

Early Human Development, 2007
The objective of this study was to gather data on the morphology of the uterus during its development, to provide detailed information regarding the neighboring structures and its variations using anatomical dissections.Eighty uteri acquired from female fetuses aged 10-40 weeks of gestation were used in this study. Firstly, the relationship between the

Fetal development in experimental uremia

Virchows Archiv A Pathological Anatomy and Histology, 1977
Uremic women on hemodialysis with metabolic bone disease (hyperparathyroidism, osteomalacia resulting from defective vitamin D metabolism) and anemia (erythropoietin deficiency) are known to give birth to infants without bone disease or anemia. Therefore, skeletal development (enchondral and desmal bone formation) and hepatic erythropoiesis were ...

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.

The development of the fetal testis in the buffalo

Zeitschrift f�r Anatomie und Entwicklungsgeschichte, 1974
The testis starts to descent at four months and is located in the scrotum at six months. The weight of the testis increases about 63-fold and is more correlated to the body weight than the CVR length. The sex cords increase in diameter about twofold and show a stagnant period between the fifth and ninth months.

Fetal development of the pyloric muscle

Surgical and Radiologic Anatomy, 1992
The fetal development of the pyloric muscle was studied in five human embryos (crown-rump length 5 to 31 mm) and in ten fetuses aged 3 to 9 months. Samples of pyloric muscle were obtained during operation for pyloric stenosis in two infants aged six weeks.
