The natural ether-lipids 1-O-alkylglycerols (alkyl-Gro) from shark liver oil improve boar sperm motility and fertility in vitro. We examined the effects of oral shark liver oil on motility and velocity parameters of sperm together with modifications of lipid composition. Eleven boars were used as control and 11 were fed with 40 g/day for 28 days and sperm(More)
Shark-liver oil (SLO) contains two bioactive lipids: alkylglycerols and n-3 PUFA. Alkylglycerols have immunostimulating and haematopoietic properties, while n-3 PUFA are essential for optimal neonatal development. We investigated the beneficial effects of dietary supplementation with 32 g SLO/d to twelve pregnant and then lactating sows (from day 80 of(More)
1-O-alkylglycerols are naturally occurring ether lipids with potent biological activities. They may interfere with lipidic signaling, and they amplify platelet-activating factor (PAF) biosynthesis in a monocyte cell line. The PAF is produced by mammalian sperm and is an important activator of sperm motility. The aim of this study was to evaluate the effect(More)
In order to investigate whether ACTH can cross the placenta of the rat at term, porcine 125I-ACTH was injected into mothers or fetuses. ACTH was then extracted from maternal and fetal plasma, using QUSO G-32, 2.5, 5, 10, 15, and 20 min after the injection of labelled ACTH. Plasma samples were also chromatographed on Sephadex G-50, fine, columns, 5 and 20(More)
To determine the angiotensin-converting enzyme (ACE) inhibitory activity of a fish hydrolysate, different methods were tested. Finally, a sensitive, extraction-free HPLC method using N-(3-[2-furylacryloyl)-PheGly-Gly (FAPGG) as substrate was preferred. This method relies on the UV-titration of the peptide 2-furylacryloyl-L-Phe (FAP) resulting from the(More)
Introduction Many ACE inhibitory peptides have been isolated from various protein hydrolysates such as casein, soybean or fish protein. The purpose of this work is to isolate ACE inhibitory peptides derived from an enzymatic hydrolysate of fish by-products named Tensideal®, which is actually produced industrially by IDMER. The measurement of ACE inhibitory(More)
