Original Article Expression of Prostaglandin-Synthesizing

limiting enzyme in the production of prostaglandins So far, in different bird species there have been found two isoforms of cyclooxygenases (COX), cyclooxy-genase 1 (COX-1) and cyclooxygenase 2 (COX-2) These isoforms along with prostaglandins are re-garded to possess a determining influence on the suc-cess in female reproduction



The human multidrug resistance protein MRP4 functions as a

May 21, 2003 · Prostaglandins are formed and secreted by most cells, and act as autocrine- or paracrine-signaling molecules In many cases they exert their effects extracellularly via interaction with a family of G protein-coupled membrane receptors (reviewed in ref 6), although some prostaglandins interact with the nuclear

Pathophysiology of Postpartum Hemorrhage and Third Stage of Labor

Prostaglandins Prostaglandins are potent stimulators of myometrial contractility, acting via cyclic AMP-mediated calcium release The therapeutic usefulness of prostaglandin agents in PPH lends credence to the possibility of a physiological role for prostaglandins in the third stage of labor The prostaglandins involved in uterine



Aspirin for Prevention of Preeclampsia

prostaglandins is dependent on PGH2, a common pre-cursor, which enables the endothelial production of prostaglandin I2 (PGI2) and platelet production of TXA2 [19, 20] Aspirin is quickly absorbed in the stomach and upper digestive tract The fraction absorbed depends on various factors, such as the dissolution of the tablets, the dosage
