Activation of Autophagy in Human Uterine Myometrium During Labor

Expression of prothrombin and protease activated receptors in human myometrium during pregnancy and labor.

As thrombin is proposed to be involved in stimulating myometrial contractility during labor and preterm labor, we aimed to investigate the expression of prothrombin (F7), the precursor of thrombin, its receptors, the protease-activated receptor (PAR) family (F2R, F2RL1, F2RL2, and F2RL3), and prothrombinase FGL2 in human myometrium during pregnancy and labor. Messenger RNA and protein were isol...

Physiological change of the human uterine myometrium during menstrual cycle: evaluation using BOLD MR imaging

A. Kido, T. Koyama, M. Kataoka, A. Yamamoto, S. Umeoka, S. Fujii, T. Saga, K. Togashi Kyoto University, Kyoto, Kyoto, Japan Introduction Uterus exhibits impressive hemodynamic change during menstrual cycle phases. During menstrual phase, prostaglandins are at their highest concentration (1). It induces uterine myometrial contractions and lead to decrease local uterine blood flow (2). Uterus als...

tranexamic acid in the control of uterine atony during labor

results hemoglobin level was 9.9 ± 5.1 in the control group six hours after hemorrhage while it was 8.10 ± 2.1 in the treatment group (p = 0.004). hemoglobin level was 5.8 ± 4.1 in the control who did not receive transfusion of blood products during the first 24 hours after hemorrhage, while this level was 7.9 ± 4.1 in the treatment group (p = 0.001). the amount of bleeding significantly declin...

The Shape of Uterine Contractions and Labor Progress in the Spontaneous Active Labor

Background: Dystocia is the most common indication of primary cesarean section. The most common cause of dystocia is uterine dysfunction. In prolonged labor, more attention is usually paid to the fetus and pelvis rather than to the role of uterine contractions in a delivery. Therefore, we decided to determine the relationship between the labor progress and uterine contractions shapes.Methods: I...
