Sinusoidal fetal heart rate may have a spectrum of occurrence that indicates degree of fetal morbidity. Twelve cases of intermittent sinusoidal fetal heart rate were reviewed for fetal outcome. Findings of anemia, low umbilical cord pH, and large base excess support that intermittent sinusoidal fetal heart rate may be an early indicator of impending fetal compromise.

Pathological analysis of placenta is currently a valuable tool for gaining insights into pregnancy outcomes. In placental histopathology, multiple functional tissues can be inspected as potential signals reflecting the transfer functionality between fetal and maternal circulations. However, the identification of multiple functional tissues is challenging due to (1) severe heterogeneity in texture, size and shape, (2) distribution across different scales and (3) the need for comprehensive assessment at the whole slide image (WSI) level.

Background: There is little information about when and how cavernosal sinusoidal endothelia develop in the external genitalia of fetuses.
Methods: We examined histological sections of erectile tissue in 37 human fetuses (25 males and 12 females) whose gestational age (GA) ranged from 8 to 40 weeks.
Results: The sinusoidal lumen was filled with blood in the glans of the penis and clitoris at a GA of 10-11 weeks, and in the corpus spongiosum at a GA of 15-16 weeks.

Background: Children born to women with hypertension during pregnancy have a two to threefold increased risk of developing cognitive disorders compared to children born to women without hypertension. However, structural changes in the central nervous system of these children remain poorly understood. We aim to compare the brain histological findings from autopsies of neonates and fetuses born to women with and without hypertension during pregnancy.

Maternal hyperhomocysteinemia (HHcy) is a risk factor for intrauterine growth restriction presumably caused by a decrease in the placental transport of nutrients. We investigated the effect of experimental HHcy induced by daily methionine administration to pregnant rats on the free amino acid levels in the maternal and fetal blood, as well as on morphological and biochemical parameters associated with the amino acid transport through the placenta. HHcy caused an increase in the levels of most free amino acids in the maternal blood on gestational day 20, while the levels of some amino acids in the fetal blood were decreased.

Background: There is no clear information on the regulation of liver blood flow by the autonomic nervous system. We conducted this study to investigate whether quiescent hepatic stellate cells (qHSCs) regulate liver blood flow in response to the sympathetic neurotransmitter norepinephrine (NE).
Methods: qHSCs isolated from mice were cultured in Dulbecco's modified Eagle medium without fetal bovine serum for 1 day on collagen gel.
