To effectively postpone preterm birth, cervical ripening needs to be detected and delayed. As the cervix ripens, the spacing between the collagen fibers increases and fills with water, hyaluronan, decorin, and enzymes suggesting that the ultrasonic attenuation of the cervix should decrease. The decrease in ultrasonic attenuation may be detectable, leading to an effective means of detecting cerv...

LiMn0.5Fe0.5PO4 (LMFP) materials are synthesized by the hydrothermal approach in an organic-free and surfactant-free aqueous solution. The phase and morphological evolution of the material intermediates at different reaction temperatures and times are characterized by XRD, SEM and TEM, respectively. The results show that during temperature increase, the solubility product (Ksp) of the precursor...

OBJECTIVES To compare the effectiveness of two dosing regimens of vaginal misoprostol for cervical ripening and induction of labour. MATERIALS AND METHODS Pregnant women with singleton low risk pregnancy at term scheduled for elective induction of labour were randomized to receive either 25 μg or 50 μg of vaginal misoprostol for pre-labour cervical ripening. All the patients received antenata...

Background This is one of a series of reviews of methods of cervical ripening and labour induction using standardised methodology. The use of complementary therapies is increasing and some women look to complementary therapies during pregnancy and childbirth to be used alongside conventional medical practice. Acupuncture involves the insertion of very fine needles into specific points of the bo...

BACKGROUND Preterm birth is the primary cause of the neonatal mortality and morbidity. There will be no preterm birth without a cervical softening. Nitric oxide (NO) is shown to be a mediator of term cervical ripening. The aim of this study was to investigate mRNA expression of the three isomers of NO synthases (NOS) and to identify them by immunohistochemistry in the human cervix at preterm bi...

Nitric oxide (NO) has been proposed as a mediator of cervical ripening. We investigated the expression, using Western blotting, and localization, using immunohistochemistry, of the nitric oxide synthase (NOS) enzymes, inducible NOS (iNOS), endothelial NOS (eNOS) and neuronal NOS (bNOS) in the human cervix during pregnancy and parturition. Cervical biopsies were obtained from non-pregnant women,...

In a prospective study a single dose PGE2 gel 0.5 mg was given in 97 Low Bishop Score subjects, 12 hrs prior to indicated oxytocin or PGE2 tab induction for cervical ripening. Analysis of 97 subjects shows that it is very highly effective. 56 primi and 21 multi delivered spontaneously with gel administration only while 4 primi and 2 multi delivered vaginally following oxytocin and 3 more cases ...

Objectives To compare three doses of oral misoprostol 50μg four hourly versus an intra-cervical Foley catheter for 24 hours, for pre-induction cervical ripening. Methods Primary investigator blinded, randomised controlled trial conducted in 180 consecutive women with singleton uncomplicated pregnancies with Modified Bishop Score (MBS) 5 at 40 weeks + 6 days gestation, allocated by stratified...
