Myocytes, Myometrium, and Uterine Contractions
Annals of the New York Academy of Sciences, 2006Abstract: The pregnant uterus is unique because of the dramatic functional changes that occur in the peripartum period. To promote the concept that we have a relatively poor understanding of the physiology of parturition, we will posit 10 facts that are so obvious and so clearly accepted as facts that they probably are not even facts at all.

The physiology of uterine contractions
Clinics in Perinatology, 2003Studies in animals and humans indicate that uterine performance can be successfully monitored during pregnancy using uterine electromyography. Uterine electromyography could be used to better define management in a variety of conditions associated with human labor.

Epidural anesthesia and uterine contractions
International Journal of Gynecology & Obstetrics, 2004It has been our anecdotal experience that midwives and doctors sometimes perceive uterine contractions to diminish in strength and frequency following the administration of epidural anesthesia. This is probably an incorrect perception, as there is no physiological reason for this phenomenon [1].

Energetics of Uterine Muscle Contraction
Nature, 1950LUNDSGAARD1 has shown that the energy liberated by striated muscle, poisoned by monoiodoacetic acid under anaerobic conditions, is proportional to the breakdown of creatine phosphate. He has also shown that under these conditions adenosinetriphosphate2 also disappeared on stimulation.

Puerperal uterine contractions
American Journal of Obstetrics and Gynecology, 1942Abstract Contractions of the puerperal uterus are clinically important for two reasons: First and most important, the contractions of the myometrium are necessary for the prevention of hemorrhage; second, they have some interest in relation to after-pains.

Changes in uterine blood flow during uterine contractions
American Journal of Obstetrics and Gynecology, 1969Abstract During spontaneous and oxytocin-induced labor, recordings were made of relative uterine blood flow (thermistor method), intrauterine pressure, femoral venous and arterial pressures, and maternal heart rate. In prelabor, uterine blood flow exhibits frequent irregular waves quite independent of the observed uterine activity. During labor there

Fractal analysis of the uterine contractions.
Rivista di biologia, 2004The fractal dimension D may be calculated in many ways, since its strict definition, the Hausdorff definition is too complicated for practical estimation. In this paper we perform a comparative study often methods of fractal analysis of time series. In Benoit, a commercial program for fractal analysis, five methods of computing fractal dimension of ...

Clinical assessment of uterine contractions
International Journal of Gynecology & Obstetrics, 2017AbstractThe assessment of uterine contractions is important in clinical decision‐making, but the precise role for appraising contractions remains controversial. Four clinical approaches to assessing contractions are available: manual palpation; intrauterine pressure determination; external tocodynamometry; and electrohysterography.

Uterine contractions in dysmenorrhea
American Journal of Obstetrics and Gynecology, 1941Abstract 1. 1. Dysmenorrhea occurs in the presence of high amplitude contractions superimposed upon tetany. 2. 2. High amplitude contractions occur only in the presence of a corpus luteum. It follows therefore, that dysmenorrhea occurs only in the ovulatory cycle. 3. 3.
