Noninvasive electromyometrial imaging of human uterine maturation during term labor

Nature Communications, 2023
Preventing preterm birth and labor arrest requires safe and accurate uterine contraction monitoring. Here, the authors show that Electromyometrial Imaging (EMMI) can image 3D uterine contraction patterns dynamically in human labor, providing new insights

Impact of prolonged use of adjuvant tocolytics after cervical cerclage on late abortion and premature delivery

Journal of Obstetrics and Gynaecology, 2023
We evaluated the impact of cervical cerclage combined with one or more uterine contraction inhibitors in persistent inhibition of uterine contraction for the treatment of late abortion and premature delivery. This retrospective case series study analysed

Linking myometrial physiology to intrauterine pressure; how tissue-level contractions create uterine contractions of labor. [PDF]

PLoS Computational Biology, 2014
The mechanisms used to coordinate uterine contractions are not known. We develop a new model based on the proposal that there is a maximum distance to which action potentials can propagate in the uterine wall. This establishes "regions", where one action

Ethanolic Extracts of Adlay Testa and Hull and Their Active Biomolecules Exert Relaxing Effect on Uterine Muscle Contraction through Blocking Extracellular Calcium Influx in Ex Vivo and In Vivo Studies

Biomolecules, 2021
Dysmenorrhea is one of the most prevalent disorders in gynecology. Historically, adlay (Coix lachryma-jobi L. var. Ma-yuen Stapf.) has been explored for its anti-tumor, pain relief, anti-inflammatory, and analgesic effects.

Extracellular Calcium and Induction of Uterine Muscle Contraction by Aqueous Ethanolic Leaf Extract of Mucuna pruriens

Journal of Applied Sciences and Environmental Management, 2020
Calcium (Ca2+) serves as an essential signaling molecule in biological systems, regulating a wide range of cellular processes of which uterine smooth muscle contraction is among.

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

Frontiers in Endocrinology, 2023
BackgroundThe 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.

Comparison of electrohysterogram characteristics during uterine contraction and non-contraction during labor [PDF]

, 2017
Uterine contraction is one of the most important indication in the labor progression. Electrohysterogram (EHG) is a promising method for monitoring uterine contraction and discriminating efficient and inefficient contractions.

Feasibility of transabdominal electrohysterography for analysis of uterine activity in nonpregnant women [PDF]

, 2018
Purpose: Uterine activity plays a key role in reproduction, and altered patterns of uterine contractility have been associated with important physiopathological conditions, such as subfertility, dysmenorrhea, and endometriosis.

Recurring patterns in stationary intervals of abdominal uterine electromyograms during gestation [PDF]

, 2014
Abdominal uterine electromyograms (uEMG) studies have focused on uterine contractions to describe the evolution of uterine activity and preterm birth (PTB) prediction. Stationary, non-contracting uEMG has not been studied.

Skeletal muscle: a significant novel neurohypophyseal hormone-secreting organ [PDF]

, 2019
Vasopressin (arg8-vasopressin) and oxytocin are closely relalated hormones, synthesized as pre-hormones in the magnocellular neurons of the paraventricular Q6 and supraoptic nuclei of the hypothalamus.
