Women's Recognition of the Spontaneous Onset of Labor
Birth, 2003Abstract: Background: Despite extensive research on the onset of labor, almost no data are available on women's perception of labor onset. We undertook a study to assess how women experience spontaneous onset of term labor.Methods: A semistructured questionnaire was given to 235 women admitted in spontaneous labor at term. Women noted when labor had

Interleukin-8 Synthesis and the Onset of Labor
Obstetrics & Gynecology, 1995To examine the role of cytokines in cervical dilation.In 55 patients undergoing cesarean delivery, we took samples from the lower uterine segment, the decidua, and the membranes. We determined the concentrations of interleukin (IL)-2, IL-8, tumor necrosis factor-alpha, matrix metalloproteinase (MMP)-8, and MMP-9 in the different tissues.Depending on ...

Vaginal cytology for prediction of onset of labor
American Journal of Obstetrics and Gynecology, 1967Abstract An evaluation of the vaginal cytologic changes occurring during the last 6 weeks of gestation was carried out in 355 pregnant women. Cytologic changes in the vaginal smears that would indicate approaching labor or the likelihood of successful induction of labor do not occur regularly at the end of pregnancy.

Phospholipids and the Onset of Labor in Rabbits
Gynecologic and Obstetric Investigation, 1970A soya bean oil containing predominantly phospholipids (SBP) has been known to sensitize the pregnant rabbit uterus to oxytocin, permitting premature induction of labor. We are attempting to identify the active component. Lipid class analyses of SBP revealed nonphospholipids, noncholine-containing phospholipids, and choline-containing phospholipids ...

Journal de gynecologie, obstetrique et biologie de la reproduction, 1984
The authors reviewed the literature in order to try to work out the different mechanisms that are responsible for labour starting. A role seems to be played by the decidua of the uterus, by the placenta and by the fetal membranes as well as the very important role of prostaglandin synthesis.

Spontaneous labor onset: is it immunologically mediated?
American Journal of Obstetrics and Gynecology, 2010The investigators tested the hypothesis that maternal-fetal immune interactions could be important in initiating spontaneous labor onset by examining if labor was delayed when fetuses share maternal HLA antigen types.HLA antigen types A, B, and DR in 200 Danish mother-infant pairs delivering in 42-44 weeks (postterm) were compared with 195 mother ...
