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]

Molecules
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.

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

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

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

PLoS 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 ...

Prostaglandin F and 13,14-dihydro-15-keto prostaglandin F in the endometrium and uterine flushings of sheep before implantation [PDF]

Reproduction, 1983
The concentrations of prostaglandin F (PGF) and its major metabolite, 13,14-dihydro-15-keto prostaglandin F-2 alpha (PGFM), were measured in caruncular and intercaruncular endometrium of pregnant and non-pregnant ewes on Days 9, 11, 13 and 15 after mating (Day 0) and related to the content of PGF and PGFM in the uterine flushings.

Differential regulation of the eicosanoid biosynthesis pathway in response to Enterocytozoon hepatopenaei infection in Litopenaeus vannamei. [PDF]

PLoS ONE
The microsporidian Enterocytozoon hepatopenaei (EHP) is a highly contagious pathogen that causes severe growth retardation in penaeid shrimp. EHP infection damages the hepatopancreatic tubules, causes hematopoietic infiltration, and recruits granulocytes

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

Heliyon, 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.

Hypothyroidism Affects Uterine Function via the Modulation of Prostaglandin Signaling

Animals, 2021
Thyroid hormones control the functions of almost all body systems. Reproductive dysfunctions, such as abnormal sexual development, infertility, or irregularities in the reproductive cycle, might be associated with thyroid disorders.

Insights into the prostanoid pathway in the ovary development of the penaeid shrimp Penaeus monodon. [PDF]

PLoS ONE, 2013
The prostanoid pathway converts polyunsaturated fatty acids (PUFAs) into bioactive lipid mediators, including prostaglandins, thromboxanes and prostacyclins, all of which play vital roles in the immune and reproductive systems in most animal phyla.

PROSTAGLANDINS F AND OVULATION IN MICE [PDF]

Reproduction, 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 & Behrman, 1972)
