Secondary sulfonamides (4a-8h) incorporating acetoxybenzamide, triacetoxybenzamide, hydroxybenzamide, and trihydroxybenzamide and possessing thiazole, pyrimidine, pyridine, isoxazole and thiadiazole groups were synthesized. Lactoperoxidase (LPO, E.C.1.11.1.7), as a natural antibacterial agent, is a peroxidase enzyme secreted from salivary, mammary, and other mucosal glands. In the present study...
OBJECTIVE To determine whether there is an increased amount of free radical-mediated damage in diseased vs healthy tissue from patients with chronic rhinosinusitis. DESIGN Pathophysiologic study. Samples of heathly and diseased tissue were taken from each patient. Lipid peroxides (LPOs) are a by-product of free radical-mediated damage; LPO levels and LPO/protein ratios were determined for eac...
INTRODUCTION Lipid peroxidation (LPO) results from oxidative damage to membrane lipids. Whereas LPO rises in normal pregnancy, the effect of gestational diabetes mellitus (GDM) on this process has not been clearly defined. MATERIALS AND METHOD Fasting blood concentrations of malondialdehyde+4-hydroxyalkenals (MDA+4-HDA), as LPO index, TNFa soluble receptors (sTNF-R1 and sTNF-R2), and soluble ...
We have previously shown that lactoperoxidase (LPO) covalently coupled to polystyrene tissue culture flasks can be used to radioiodinate monolayer cell proteins that come into intimate contact with the LPO-polystyrene surface. These studies have now been extended to include a detailed examination of the class of iodinated polypeptides migrating with apparent molecular weights of 50,000 and 55,0...
Oxidative stress and lipid peroxidation (LPO) induced by inflammation, excess metal storage and excess caloric intake cause generalized DNA damage, producing genotoxic and mutagenic effects. The consequent deregulation of cell homeostasis is implicated in the pathogenesis of a number of malignancies and degenerative diseases. Reactive aldehydes produced by LPO, such as malondialdehyde, acrolein...
This paper describes the verification module (the VipVerify Module) of the VipTool [4]. VipVerify allows to verify whether a given scenario is an execution of a system model, given by a Petri net. Scenarios can be graphically specified by means of Labeled Partial Orders (LPOs). A specified LPO is an execution of a Petri net if it is a (partial) sequentialization of an LPO generated by a process...
Human spermatozoal motility, viability and lipid peroxidation (LPO) have been assessed in Ringer-Tyrode supplemented with different concentrations of ascorbic acid (AA) ranging from 50 to 4000 microM. Ascorbic acid in concentrations below 1000 microM protects spermatozoa from free radical damage as evidenced from improvement in their motility and viability. Concomitantly, there is also witnesse...
Lipid peroxidation (LPO) is induced by a variety of abiotic and biotic stresses. Although LPO is involved in diverse signaling processes, little is known about the oxidation mechanisms and major lipid targets. A systematic lipidomics analysis of LPO in the interaction of Arabidopsis (Arabidopsis thaliana) with Pseudomonas syringae revealed that LPO is predominantly confined to plastid lipids co...
This paper introduces a new kind of propositional encoding for reasoning about partial orders. The symbols in an unspecified partial order are viewed as variables which take integer values and are interpreted as indices in the order. For a partial order statement on n symbols each index is represented in dlog2 ne propositional variables and partial order constraints between symbols are modeled ...
Tea prepared from the aerial parts of Antigonon leptopus is used as a remedy for cold and pain relief in many countries. In this study, A. leptopus tea, prepared from the dried aerial parts, was evaluated for lipid peroxidation (LPO) and cyclooxygenase (COX-1 and COX-2) enzyme inhibitory activities. The tea as a dried extract inhibited LPO, COX-1 and COX-2 enzymes by 78%, 38% and 89%, respectiv...
