Changes in the autonomic cardiorespiratory activity in parturient women with severe and moderate features of preeclampsia.

Background: Cardiorespiratory coupling (CRC) is a physiological phenomenon that reflects the mutual interaction between the cardiac and respiratory control systems. It is mainly associated with efferent vagal activity from the central autonomic network. Few studies have explored the autonomic changes of CRC in preeclampsia, a critical obstetric complication related to possible autonomic dysfunctions and inflammatory disturbances.

Uterine activity modifies the response of the fetal autonomic nervous system at preterm active labor.

Background: The autonomic nervous system of preterm fetuses has a different level of maturity than term fetuses. Thus, their autonomic response to transient hypoxemia caused by uterine contractions in labor may differ. This study aims to compare the behavior of the fetal autonomic response to uterine contractions between preterm and term active labor using a novel time-frequency analysis of fetal heart rate variability (FHRV).

A Translational Perspective of Maternal Immune Activation by SARS-CoV-2 on the Potential Prenatal Origin of Neurodevelopmental Disorders: The Role of the Cholinergic Anti-inflammatory Pathway.

The emergent Coronavirus Disease 2019 (COVID-19) caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) could produce a maternal immune activation (MIA) via the inflammatory response during gestation that may impair fetal neurodevelopment and lead to postnatal and adulthood mental illness and behavioral dysfunctions. However, so far, limited evidence exists regarding long-term physiological, immunological, and neurodevelopmental modifications produced by the SARS-CoV-2 in the human maternal-fetal binomial and, particularly, in the offspring. Relevant findings derived from epidemiological and preclinical models show that a MIA is indeed linked to an increased risk of neurodevelopmental disorders in the offspring.

NF-κΒ and SOD expression in preeclamptic placentas.

Background/aim: Preeclampsia is a leading cause of maternal death in the developing world. Our aim was to quantify and compare messenger (mRNA) expression of nuclear factor-kappa beta (NF-κΒ) and superoxide dismutase (SOD) in control patients with preeclampsia and without preeclampsia with or without familial hereditary background.

Materials And Methods: Four groups of patients were formed depending on the presence or absence of preeclampsia and presence or absence of familial history for preeclampsia.

Evaluation of the Effect of 1,3-Bis(4-Phenyl)-1H-1,2,3-Triazolyl-2-Propanolol on Gene Expression Levels of JAK2-STAT3, NF-κB, and SOCS3 in Cells Cultured from Biopsies of Mammary Lesions.

Breast cancer is the most frequent neoplasia in women and is responsible for approximately 13.8% of deaths per year for this gender. It has been suggested that JAK2, STAT3, and NF-κB gene expression is involved in this type of cancer.
