OBJECTIVE We aimed to evaluate the performance of a non-invasive EMG electrical uterine monitor (EUM) versus tocodynamometry (TOCO) by comparing both to internal uterine pressure catheter (IUPC). STUDY DESIGN Prospective observational trial. Uterine activity was recorded continuously and simultaneously, in women during active term labor, with TOCO, EUM and IUPC. Uterine activity tracings were...

Two cases of uterine perforation are described, occurring 11 days and 4 months, respectively, after the insertion of GyneFix, a frameless intra-uterine contraceptive device (IUD). In both the cases initial ultrasound scan showed the intra-uterine position of the device. Removal of the IUD, either by laparoscopy or laparotomy, had to be carried out. Awareness of this complication, insertion of G...

Uterine vascular tone significantly decreases whereas uterine blood flow dramatically increases during pregnancy. However, the complete molecular mechanisms remain elusive. We hypothesized that increased Ca -activated K (BKCa) channel activity contributes to the decreased myogenic tone of uterine arteries in pregnancy. Resistance-sized uterine arteries were isolated from nonpregnant and near-te...

This overview describes and illustrates the clinical applications of three-dimensional transvaginal sonography in reproductive medicine. Its main applications include assessment of uterine anomalies, intrauterine pathology, tubal patency, polycystic ovaries, ovarian follicular monitoring and endometrial receptivity. It is also useful for detailed evaluation of failed and/or ectopic pregnancy. T...

Uterine vascular tone significantly decreases whereas uterine blood flow dramatically increases during pregnancy. However, the complete molecular mechanisms remain elusive. We hypothesized that increased Ca(2+)-activated K(+) (BK(Ca)) channel activity contributes to the decreased myogenic tone of uterine arteries in pregnancy. Resistance-sized uterine arteries were isolated from nonpregnant and...

A simple technique has been described by Wigglesworth (1937) for the determination of chloride in as little as 0-3 ,ul. of fluid. This is based on the Volhard titration and has been used in this Laboratory since 1947 for the examination of fish and crustacean blood. While the results obtained were satisfactory, the tedious back titration and the comparatively impermanent end point were found to...

since the uterine is a sensitive tissue to steroid hormones, the aim of the present study was to investigate the effects of 17β-estradiol (e2) and progesterone (p4) alone or in combination on morphological and morphometrically parameters of ovariectomized mouse uterus.adult virgin female mice (8-10 weeks old)were ovariectomized and treated with e2, p4, e2 followed by p4 and the oil vehicle alon...

The frequency-dependent complex moduli of human uterine tissue have been characterized. Quantification of the modulus is required for developing uterine ultrasound elastography as a viable imaging modality for diagnosing and monitoring causes for abnormal uterine bleeding and enlargement, as well assessing the integrity of uterine and cervical tissue. The complex modulus was measured in samples...
