Modeling And Detection Of Uterine Contractions Using Magnetomyography
… framework for modeling and analyzing uterine contractions using biomagnetic measurements. The study of myometrium contractility during pregnancy is relevant to the field of reproductive assessment. Its clinical importance is grounded in the need for a better understanding of the …

Development, Validation, and Application of Electromyometrial Imaging (EMMI) to Noninvasively Image Uterine Contractions
<p>Clinically, uterine contraction and labor progression are monitored via tocodynamometers (TOCO) or intrauterine pressure catheters (IUPC). However, these clinical tools measure the crude pressure information and have limit specificity and accuracy in differentiating the contractions, whether …

Physiological Response of uterine muscle to aqueous root extract of Steganoteania Araliacea Hochst (Herbal''Pitocin'') in Rats
… of SAEª on isolated pregnant and non-pregnant uterine muscle. Methods: A gravid/non-gravid rat was sacrificed by cervical dislocation (decapitation) method and the abdomen opened to expose the internal organs. The two uterine horns were identified, dissected out and transferred to a dish …

Oxytocin-induced cervical dilation in sheep: mechanism of action and potential use for nonsurgical artificial insemination
… rate (Exp. 9). Oxytocin probably binds to uterine and cervical receptors (Exp. 6) and stimulates uterine tetany (Exp. 2) and prostaglandin release (Exp. 5). Because of the irregular arrangement of smooth muscle in the sheep cervix (Exp. 4), uterine tetany may physically dilate the cervix. …

Calibration of sonographic gel probe covers for in-vivo mechanical testing
… asymptomatically dilates in the absence of uterine contractions, resulting in a spontaneous preterm delivery. The condition is often misdiagnosed and presents a significant challenge for the clinical community. In order to establish better diagnostic criteria for cervical insufficiency and …

Assessment of Biomarkers of Intrauterine Inflammation Induced Preterm Labor
… birth before 37 weeks, is the manifestation of uterine contractions with sufficient frequency and intensity to cause progressive cervical thinning and dilation of the cervix prior to term gestation. Preterm labor is a consequence of a complex cluster of complications with many overlapping …

Obstructed labour and Birth preparedness: Community studies from Uganda
… descend through the birth canal despite strong uterine contractions. The condition is mostly prevalent in low-income countries where the main causes are cephalopelvic disproportion and malpresentation. The overall aim of this thesis was to investigate the individual, community and health system …

Comparability of an innovative Doppler ultrasound fetal heart rate monitor to a pinard fetal stethoscope using cardiotocography as a standard to assess the fetal heart rate in singleton pregnancies during labour at Mowbray Maternity Hospital
… before and after two preferably consecutive uterine contractions. The midwives were blinded to the CTG measurements by silencing the CTG and turning it away from their view. The FHRs taken with a PFS were done over a 60 second period in accordance with the guidelines from professional bodies …

Classification Techniques Using EHG Signals for Detecting Preterm Births
… to the fact that the exact cause of premature uterine contractions leading to delivery is mostly unknown. Another problem is the interpretation of temporal and spectral characteristics of Electromyography (EMG), which is an electrodiagnostic medicine technique for recording and evaluating the …

The Role of PRICKLE1 in the Regulation of Uterine Structure and Physiology
… each playing an important role in supporting uterine functions through intricate interactions. The innermost layer of the uterus, the endometrium, is critical for successful implantation and pregnancy. The smooth muscle cells of the myometrial layer are organized into several sub-layers with …

Studies on the factors that improve the outcome of IVF-ET
… My results show that exaggerated junctional zone contractions do indeed have a detrimental effect on the outcome of IVF-ET our data shows that the pregnancy rate for those who had less than 5 uterine contractions per 2 minutes as compared to the pregnancy rate for patients who had more than 5 …

Inflammatory response in maternal serum during preterm labour
… and a molecular pathophysiology defined. Intrauterine infection evokes an immune response that involves the release of cytokines and chemokines, prostaglandins and matrix-degrading enzymes. These substances trigger uterine contractions, membrane rupture and cervical ripening. Most intra-uterine …
