The physiological importance of prostaglandins in the mechanism of human labor

Abstract

Recent results indicate that prostaglandins play a major role in the mechanism of human labor. There are, however, no systematic studies on the role of prostaglandins in various forms of induction of labor. In the present study the concentration of 13,14-dihydro,15-ketoprostaglandin F2 (PGFM) in the maternal peripheral plasma was determined in labor of spontaneous onset, in labor after induction with oxytocin and in labor after induction by artificial rupture of membranes (ARM). In an additional group of women PGFM was determined before and immediately after delivery to get an insight into the mechanism of placental separation. In labor of spontaneous onset PGFM concentration increased significantly. In labour induced by oxytocin PGFM levels rose only in those women in whom induction of labor was successful. In induction of labor by ARM, PGFM level also increased in all women in whom induction was successful. At the time of placental separation PGFM concentration in the maternal blood increased dramatically. From the result of this study it is concluded that the increase of prostaglandin F synthesis is a necessary prerequisite for vaginal delivery and that prostaglandins are of major importance in the mechanism of placental sep...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
