The uterus is subject to stretch throughout pregnancy, which, in the presence of progesterone, is a potent stimulus for uterine growth. However, in the absence of progesterone or when stretch is excessive, as in multiple pregnancy, it may provoke the onset of labour. We have investigated the effect of stretch on prostaglandin synthesis in primary human(More)
Parturition involves the synchronization of myometrial activity and structural changes of the cervix, leading to regular co-ordinated uterine contractions and cervical dilatation and effacement. The biochemical events involved in parturition resemble an inflammatory reaction, with growing evidence pointing to a crucial role for pro-inflammatory cytokines(More)
Premature activation of the inflammatory processes that mediate human parturition leads to preterm birth, a major clinical problem associated with neonatal morbidity and mortality. Histone deacetylase inhibitors (HDACi) are currently in clinical trials for the treatment of inflammatory disorders. Recent evidence suggests that there may be a therapeutic use(More)
Stretch of the uterus plays a role in parturition. Uterine stretch also leads to stretch of the fetal membranes, including the amnion, an important source of prostaglandin E2 (PGE2). We tested the hypothesis that stretch of the amnion leads to increased cyclooxygenase (COX)-2 expression and PGE2 synthesis and investigated the mechanisms involved. We(More)
Cardiac disease remains the leading cause of maternal death in the UK, and data from the Centre for Maternal and Child Enquiries have shown that the numbers of women dying from cardiac disease have steadily increased over the past 30 years. The incidence of acquired heart disease is increasing because of older age at first pregnancy, as well as a higher(More)
AIM Prostane, a polyherbal formulation, was evaluated for its efficacy on 5alpha-reductase inhibition, alpha-adrenergic antagonistic activity and testosterone-induced prostatic hyperplasia. METHODS 5alpha-reductase inhibition was evaluated using rat prostate homogenate as an enzyme source. Adrenergic antagonistic activity was evaluated using isolated rat(More)
We describe a patient with inactive systemic lupus erythematosus (SLE) presenting with sudden haemothorax, due to a ruptured internal mammary artery (IMA) aneurysm 7 years after the corticosteroid treatment was terminated. The unusual imaging findings and the treatment with embolization are discussed with a view to the role of a regular vascular screening(More)
OBJECTIVE Uterine overdistention is thought to induce preterm labor in women with twin and multiple pregnancies, but the pathophysiology remains unclear. We investigated for the first time the pathogenesis of preterm birth associated with rapid uterine distention in a pregnant nonhuman primate model. STUDY DESIGN A nonhuman primate model of uterine(More)
