background: congenital uterine malformations are the result of disturbances in mullerian duct development. in patients with recurrent miscarriage, the reported frequency of uterine anomalies varies widely, from 1.8% to 37.6%. there are reports in which cervical cerclage has been shown to prevent preterm labor in uterine anomalies. the aim of this study was to compare the role of cervical cercla...

UNLABELLED Bisphenol-A (BPA), dichrolodiphenyltrichloroethane (DDT) and vinclozolin were found able to induce abnormal uterine contraction. The mechanisms involved remains unclear. We hypothesized that the effect of these compounds were mediated via the uterotonin pathways. Therefore, in this study, effects of BPA, vinclozolin and DDT-only and in combination with uterotonins (PGF-2α, acetylchol...

70  Abstract— Uterine contractions are important in many reproductive functions including the transport of sperms and embryo, menstruation, pregnancy and parturition. Improper or irregular uterine activity may underlie the common pathological disorders such as infertility, improper implantation, preterm labor, and weak uterine contraction during labor. In addition, successful labor is controll...

This article proposes a method for modeling and classification apply on the uterine contractions in the electromyogram (EMG) signal for the detection of preterm birth. The frequency content of the contraction changes from one woman to another and during pregnancy. Firstly we apply an AR model on the Uterine EMG signal for the calculation of the ai parameters. Wavelet decomposition is used to ex...

background: punica granatum linn. (pg) is native to the mediterranean region. its flower exhibited antioxidant activity. the present study attempt to investigate the effect of these extract on uterine contraction and its possible mechanism(s). methods: thirty five female wistar rats (200-300 g) at estrous phases of cycle was examined in this study; pieces of virgin adult rat uterus (1.5 cm) wer...

Objective The aim of this study was to investigate the effect and mechanism by which progesterone regulates uterine contraction in late pregnant rats. Results Progesterone caused concentration-dependent relaxation of uterine strips that was enhanced compared with control nontreated uterine strips. Uterine strips incubated with progesterone showed a significant increase in TREK-1 mRNA expressi...

The aim of the study is to investigate the feasibility of pre-operative autologous blood donation (PABD) self-transfusion on the postpartum recovery and the endocrine in lying-in women. The PABD is carried out on 70 pregnant women who have high risk of postpartum hemorrhage. Those 70 subjects were divided into three groups: 33 cases of PABD self-transfusion during the Cesarean section; 16 cases...

The mechanism of uterine muscle contraction stimulated by a triterpenoid glycoside (dalsaxin) isolated from the root of D. saxatilis was investigated by in vitro methods in the rat. Dalsaxin caused a dose-related increase in uterine muscle contraction. The contraction was single and transient and was abolished by moderate doses of isoprenaline (1.80 nmol-0.40 mumol) and salbutamol (0.13-25 mumo...

Trauma during pregnancy is remarkably common, and is greatly underestimated in terms of its contribution to both maternal and perinatal morbidity and mortality. Motor vehicle crashes, falls, assaults, including domestic violence, are all important mechanisms of injury, and clinical algorithms have been developed to manage the injured pregnant women. Focus on recognition and management of the mo...
