Chymotrypsin catalyses a condensation reaction between 1-methyl-3,4-dihydro-beta-carboline-3-methyl carboxylate and amino acid amides or peptides, yielding fluorescent derivatives. During the peptide bond formation, the enzyme ensures the reaction's

Apres la decouverte des fonctions du monoxyde d’azote (NO), de nombreux mecanismes de signalisation impliquant NO ont ete mis en evidence chez les Mammiferes. NO active la guanylyl cyclase et conduit a la production de cGMP ; il stimule l’ADP rib

In order to demonstrate the involvement of nitric oxide in the defence systems of marine bivalves, we investigated the production of superoxide and nitrite, following in vitro phorbol myristate acetate stimulation of Mytilus galloprovincialis, Crasso

Peroxynitrite is a strong endogenous oxidant generated by the reaction of nitric oxide with superoxide that can damage subcellular organelles, membranes and enzymes through its actions on proteins, lipids and DNA. In a cell free system, peroxynitrite

Serotonin (5-hydroxytryptamine, 5-HT) significantly and dose-dependently suppressed the luminol-enhanced chemiluminescence (CL) signal generated by polymorphonuclear leukocytes (PMN) activated with phorbol myristate acetate (PMA), but did not modify

To assess the role of superoxide (O2−) and nitric oxide (NO) in ischaemic-reperfusion-induced acute renal failure, we investigated whether an activation of the L-arginine-NO pathway contributes to ischaemia-reperfusion-induced kidney membrane perox

We measured the amounts of tyrosine and 3-nitrotyrosine (NO2-tyrosine) in proteins of plasma and polymorphonuclear leukocytes (PMN) from human whole blood before and after activation with phorbol ester (PMA) or calcium ionophore (A 23187). In unstimu

The effects of peptides derived from bovine casein hydrolysates were evaluated on oxygen-free radical release, 5-hydroxyeicosatetraenoic acid (5-HETE), and leukotriene B4 (LTB4) production by human polymorphonuclear leukocytes (PMNs). PMNs were activ

[Met]-enkephalin or its precursor, pre-[Met]-enkephalin, were exposed to activated oxygen species produced by human phorbol myristate acetate (PMA)-stimulated polymorphonuclear leukocytes (PMNs) and then analyzed by high-pressure liquid chromatograph

Malonaldehyde (MDA), a decomposition product of lipid hydroperoxides which is used as an indicator of oxidative damage to cells and tissues, reacts, in vitro , with hydrogen peroxide to form undetermined degradation products. Since human polymorphonu
