Characterization of Uterine Motion in Early Gestation Using MRI-Based Motion Tracking
Diagnostics, 2020 Magnetic resonance imaging (MRI) is a promising non-invasive imaging technique that can be safely used to study placental development and function. However, studies of the human placenta performed by MRI are limited by uterine motion and motion in the ...

Fine spatiotemporal activity in contracting myometrium revealed by motion-corrected calcium imaging [PDF]
, 2014 Successful childbirth depends on the occurrence of precisely coordinated uterine contractions during labour. Calcium indicator fluorescence imaging is one of the main techniques for investigating the mechanisms governing this physiological process and ...

Characterization of the tissue-level Ca2+signals in spontaneously contracting human myometrium [PDF]
, 2012 In the labouring uterus, millions of myocytes forming the complex geometrical structure of myometrium contract in synchrony to increase intrauterine pressure, dilate the cervix and eventually expel the foetus through the birth canal.

Life, 2022 Background: In obesity, the adipose tissue becomes a very significant endocrine organ producing different factors called adipokines, such as leptin, adiponectin and kisspeptin; however, no data are available about their actions on uterine contraction in ...

Endothelin-dependent vasoconstriction in human uterine artery: application to preeclampsia. [PDF]
PLoS ONE, 2011 BACKGROUND: Reduced uteroplacental perfusion, the initiating event in preeclampsia, is associated with enhanced endothelin-1 (ET-1) production which feeds the vasoconstriction of uterine artery. Whether the treatments of preeclampsia were effective on ET-

3D power Doppler ultrasound assessment of placental perfusion during uterine contraction in labor [PDF]
, 2017 香川大学Kagawa University博士（医学）Introduction To assess placental perfusion during spontaneous or induced uterine contraction in labor at term using placental vascular sonobiopsy (PVS) by 3D power Doppler ultrasound with the VOCAL imaging analysis program ...

Blood vessel assessment using computed tomography : Effects of ephedrine on uterine artery
Frontiers in Pharmacology, 2022 Background: Ephedrine increased blood pressure due to the contractile properties of resistance vessels. Excessive contraction of the uterine arteries might cause fetal distress. This study was to determine the diameter of the uterine artery of female New

The role of mitochondria in uterine contractions [PDF]
FEBS Letters, 1975 The contractile activity of smooth muscle, like that of all muscle types, is controlled by changes in the myoplasmic free calcium ion concentration [ 131. Muscle concentration is initiated by a rise in the calcium concentration and relaxation occurs when the calcium level has been lowered to the initial level. It is known that extra-cellular calcium is

Fetal heart rate power spectrum response to uterine contraction [PDF]
, 2006 Cardiotocography is the most diffused prenatal diagnostic technique in clinical routine. The simultaneous recording of foetal heart rate (FHR) and uterine contractions (UC) provides useful information about foetal well-being during pregnancy and labour ...
