Cytokines such as monocyte chemotactic peptide-1 (MCP-1), interleukin-8 (IL-8), RANTES (Regulated on Activation and Normally T-cells Expressed and presumably Secreted) and interleukin-10 (IL-10) are thought to play pivotal roles in immune recognition, acceptance of the fetal allograft, maintenance of pregnancy and parturition. Their secretion and regulation(More)
Human seminal plasma has potent anti-inflammatory properties which are thought to confer a survival advantage to the spermatozoa within the hostile female genital tract. In contrast, a profound pro-inflammatory leukocytosis has been observed post-coitus in animals and humans. Whether components of seminal plasma are involved in initiating this leukocytic(More)
Sleep-disordered breathing and snoring are common in pregnancy. The aim of this study was to determine whether pregnancy was associated with upper airway narrowing. One-hundred females in the third trimester of pregnancy were recruited and 50 agreed to be restudied 3 months after delivery. One-hundred nonpregnant females were also recruited. Upper airway(More)
RATIONALE High resolution computed tomography (HRCT) is a more sensitive tool for detecting early cystic fibrosis (CF) lung disease than either spirometry or plain radiography, but its relationship to other measures of lung function has not been established in young children. OBJECTIVES (1) To assess whether the lung clearance index (LCI) derived from(More)
Both prostaglandins and antiprogestagens can induce labour and ripen the cervix, but the mechanisms are unclear. The collagenases that bring about cervical ripening are neutrophil derived. We examined the potential of uterine tissues to control neutrophil attraction by measuring interleukin-8 production. Choriodecidual cells in culture produced substantial(More)
At parturition, breakdown of extracellular matrix in the fetal membranes may play a part in the rupture of the membranes and in the aetiology of premature rupture, in addition to having a regulatory role in the cell-cell interactions and signalling at the feto-maternal interface to stimulate myometrial contractility. The matrix metalloproteinases (MMPs) are(More)
A randomised study of 189 deliveries was conducted to compare performance in the conventional dorsal position with that in a birth chair. There was no significant difference in the length of the second stage of labour, the time spent bearing down, or the need for operative delivery. Overall blood-loss was greater among patients delivered in the chair but(More)
Secretory leukocyte protease inhibitor is a potent inhibitor of neutrophil function, a mediator of mucosal immunity and an inhibitor of NF|gkB regulated inflammatory responses. However, its source, function and regulation within the uterus during pregnancy and at parturition are not well defined. In amniotic fluid, the concentration of secretory leukocyte(More)
Matrix metalloproteinases (MMPs) are important enzymes in tissue remodelling, a key event for the development of the fetal membranes and placenta and establishing the feto-maternal interface during early pregnancy. This study has examined the secretion of the gelatinases, MMP-2 (72 kDa) and MMP-9 (92 kDa), and the endogenous tissue inhibitors of(More)
