Mechanisms regulating uterine contractility are poorly understood. We hypothesized that a specific isoform of small conductance Ca(2+)-activated K(+) (SK) channel, SK3, promotes feedback regulation of myometrial Ca(2+) and hence relaxation of the uterus. To determine the specific functional impact of SK3 channels, we assessed isometric contractions of uterine strips from genetically altered mic...
the present study evaluate the histopathologic findings and clinical indications in hysterectomized patients based on sonographic assessments. this study population consisted of all patients who were referred to the pathology ward of imam reza educational and treatment center (kermanshah, iran) during march 2006 to may 2012. the samples were stained with hematoxylin-eosin after fixation in form...
This ex vivo study focuses on the mechanisms of endothelium-dependent dilatation in the uterine circulation of normal pregnancy (n = 12) and in women with preeclampsia (n = 12). Arteries (internal diameter, ∼250 μm) isolated by myometrial biopsy from women undergoing planned cesarean delivery or delivery as a result of the deterioration of preeclampsia were studied using a wire myograph. Bradyk...
We investigated intrauterine growth restriction, endothelial function, and uterine artery blood flow characteristics in a transgenic preeclampsia rat model with an activated renin-angiotensin system. We compared preeclamptic Sprague-Dawley (SD-PE) rats with normal pregnant Sprague-Dawley and nonpregnant Sprague-Dawley rats. We used transabdominal ultrasound and found that SD-PE rat embryos deve...
background: mullerian adenosarcoma, a rare tumor, is composed of mixed mesenchymal and epithelial elements. the epithelial component is typically benign and admixed with malignant sarcomatous stroma. this tumor can be distinguished in approximately 8% of all uterus sarcomas and commonly originates in the endometrium as a growing polypoid mass in the uterine cavity. all age groups are affected b...
The molecular mechanisms regulating uterine relaxation and contraction during pregnancy are poorly understood. In the present study, we used for the first time a functional genomics approach applying gene array technology to identify novel candidate genes involved in the regulation of uterine quiescence and contractility during pregnancy. The purpose of this approach was to obtain a molecular s...
BACKGROUND A significant number of women are referred with bleeding problems related to the use of hormonal contraception, for advice on management of heavy periods or following difficulty with intrauterine device insertion. The authors describe their experience with Instillagel(®) as the contrast medium for hysterosonography in a one-stop clinic for complex contraception referrals. They also c...
