This is to compare the volumes of irrigant apically extruded by five irrigation systems in an artificial socket model simulating clinical conditions. Twenty extracted human single-rooted teeth were enlarged to size 40/04 and then embedded in silicone

To investigate neutrophil interactions with mediators released by mast cells at sites of inflammation, stimulated neutrophils were incubated with histamine. No accumulation of chlorinated histamine derivatives was detected in the medium. Instead, his

Neutrophils prevent infection by ingesting and killing microorganisms but oxidants and proteases released by neutrophils damage host tissues. Our aim was to identify factors that regulate oxidant production by the enzyme myeloperoxidase (MPO) followi

Myeloperoxidase and eosinophil peroxidase catalyzed the oxidation of bromide ion by hydrogen peroxide (H2O2) and produced a brominating agent that reacted with amine compounds to form bromamines, which are long-lived oxidants containing covalent nitr

Two-dimensional isoelectric focusing and gel electrophoresis followed by mass spectrometry were used to detect, measure, and identify changes in protein expression correlated with differences in the metastatic potential of cultured rat mammary adenoc

Isolated human neutrophilic leukocytes were stimulated to produce hydrogen peroxide (H2O2) and to secrete cytoplasmic granule components including myeloperoxidase into the medium. Myeloperoxidase catalyzed the oxidation of chloride (Cl-) by H2O2 to y

Human saliva was fractionated to determine the components required for production and accumulation of the antimicrobial oxidizing agent, hypothiocyanite ion (OSCN-). The required components were: 1) peroxidase activity and thiocyanate ion (SCN -), 2)

Incubation of stimulated neutrophils with sulfhydryl (RSH) compounds or ascorbic acid (ascorbate) results in rapid superoxide (O2-)-dependent oxidation of these reducing agents. Oxidation of RSH compounds to disulfides (RSSR) is faster than the rate

Myeloperoxidase-catalyzed oxidation of chloride (Cl-) to hypochlorous acid (HOCl) resulted in formation of mono- and dichloramine derivatives (RNHCl and RNCl2) of primary amines. The RNCl2 derivatives could undergo a reaction that resulted in incorpo
