Collision-Induced Gas-Phase Reactions of PFB-TMS Derivatives of F2-Prostaglandins in Quadrupole GC-NICI-MS/MS: A Mini-Review and a Meta-Analysis [PDF]

open access: yesMolecules
Arachidonic acid (eicosatetraenoic acid) is the precursor of the eicosanoids, which include prostaglandins (PG). Methods based on GC-MS/MS are the Gold Standard for the quantitative analysis of eicosanoids in biological samples.

PROSTAGLANDINS F AND OVULATION IN MICE [PDF]

open access: yesReproduction, 1974
Prostaglandins (PGs) are known to exert profound physiological and pharmacological effects on the female reproductive system in women and in many other species (Weeks, 1972; Labhsetwar, 1974). Indomethacin and aspirin, inhibitors of prostaglandin biosynthesis, block PMSG-induced ovulation in immature (Armstrong & Grinwich, 1972; Orczyk & ...

Prostaglandins E and F in Endocrine Diarrheagenic Syndromes

open access: yesAnnals of Surgery, 1976
The role of prostaglandins in endocrine diarrheagenic syndromes was evaluated by measuring peripheral concentration of immunoreactive PGE and PGF in patients with non-endocrine diarrhea as well as those with the Zollinger-Ellison (Z-E) syndrome, MCT, carcinoid tumors and the WDHA syndrome. In 21 normals, PGE and PGF levels averaged 272 +/- 18 and 119 +/

Identification and characterization of prostaglandin F2α 9-dehydrogenase from Rhodotorula kratochvilovae [PDF]

open access: yesApplied Microbiology and Biotechnology
Prostaglandin F2α (PGF2α) is one of the most important bioactive lipids in mammals. Developing a bioproduction system for PGF2α could enable low-cost production with minimal environmental impact.

Biomarkers and Mechanisms of Male Infertility: Evaluation of Antioxidant Enzymes and Arachidonic Acid Derivatives in Seminal Plasma from Fertile and Infertile Men [PDF]

open access: yesAntioxidants
Male infertility accounts for approximately 50% of reproductive failures, yet its diagnosis and understanding of underlying mechanisms remain limited.

Improved de novo production of prostaglandin F2α from glucose with engineered Yarrowia lipolytica strains [PDF]

open access: yesCommunications Biology
Prostaglandin F2α (PGF2α) is an important lipid mediator with diverse physiological activities, but its reliance on chemical synthesis presents challenges and limitations, driving the need for efficient microbial fermentation.

A heterogeneous mixture of F-series prostaglandins promotes sperm guidance in the Caenorhabditis elegans reproductive tract. [PDF]

open access: yesPLoS Genetics, 2013
The mechanisms that guide motile sperm through the female reproductive tract to oocytes are not well understood. We have shown that Caenorhabditis elegans oocytes synthesize sperm guiding F-series prostaglandins from polyunsaturated fatty acid (PUFA ...

The physiological basis with uterine myometrium contractions from electro-mechanical/hormonal myofibril function to the term and preterm labor

open access: yesHeliyon, 2023
Background: Most labor-related problems can be attributed to the uterine myometrium muscle, as this irritable tissue must suppress its irritability potential during pregnancy.
