Composition of the neutral lipids of bovine meilbomian secretions.
Lipids secreted form the bovine meibomian glands were assigned to following classes: cholesteryl esters (A) (fatty acyl chain lengths from 15 to 27 carbon atoms), 41%; wax esters, 29%; triacylglycerols, 10%; and cholesteryl ester (B) (fatty acyl chain lengths from 14 to 18 carbons), 15%. The remaining 5% consisted of cholesterol, fatty acids, and highly polar material. Analysis of the lipids sh...
متن کاملSummer heat stress affects prostaglandin synthesis in the bovine oviduct.
Summer heat stress (HS) negatively affects reproductive functions, including prostaglandin (PG) F2α secretion in the endometrium, and decreases fertility in cattle. In the present study, we examined the effects of elevated temperatures on PG synthesis in oviductal epithelial cells. The epithelial cells obtained from the ampulla and isthmus of the oviduct were incubated at various temperatures (...
متن کاملPhysiology and endocrinology symposium: evidence that oviduct secretions influence sperm function: a retrospective view for livestock.
The mammalian oviduct has long been recognized as an organ essential for successful reproduction. Bovine, ovine, porcine, and equine animal models have offered clear advantages for oviduct study related to gamete physiology, fertilization, and early embryonic development. Livestock species are amenable to surgical alteration of the reproductive tract, estrous cycle manipulation, gamete cryopres...
متن کاملThree year results of in vitro production of bovine embryos in serum-poor bovine oviduct conditioned medium. An overview.
This paper presents a synthesis of 3 year results of in vitro production of bovine embryos in medium previously conditioned by bovine oviduct epithelial cells. In Louvain-la-Neuve, Belgium, a total of 18356 oocytes were matured and inseminated in vitro: 13967 (76%) had cleaved at 3 days post-insemination and 3593 (26%) became blastocysts using this culture system. Our data show that conditioned...
