The replicator region of composite plasmid pTAV1 of Paracoccus versutus (included in mini-replicon pTAV320) belongs to the family of repABC replicons commonly found in plasmids harbored by Agrobacterium and Rhizobium spp. The repABC replicons encode three genes clustered in an operon, which are involved in partitioning (repA and repB) and replication(More)
Obstructive sleep apnea (OSA) is an independent risk factor in the pathogenesis of -cardiovascular diseases. The aim of the study was to analyze three specific adhesion molecules involved in the development of an atherosclerotic plaque: E-selectin (endothelium), L-selectin (leukocyte surface), and P-selectin (from platelet), circulating in plasma in(More)
The aim of the study was to determine some biochemical factors reflecting oxidant-antioxidant balance in the blood of patients being in different stages of the obstructive sleep apnea syndrome (OSAS). The patients, suspected of OSAS, were submitted to biochemical and somnographic examinations. APolyMesam device was used to establish the severity of apnea(More)
OBJECTIVE The relationship between obstructive sleep apnea (OSA) and cardiovascular disease is intensively discussed. Endothelial leukocyte adhesion molecule (E-selectin) is one of factors facilitating leukocyte migration to the subendothelial layer which could be considered proatherogenic. The aim of the study was to determine E-selectin levels and total(More)
The oxygen radicals produced by polymorphonuclear neutrophils (PMN) during ischemia and reperfusion play an important role in the development of arrhythmias. We investigated the influence of selected antiarrhythmic drugs on PMN superoxide anion production. Amiodarone, verapamil and propranolol significantly decreased the stimulated superoxide anion(More)
A balance between oxidant carcinogens and endogenous antioxidant defence is of particular relevance to the carcinogenesis. Ceruloplasmin (Cp) carries up to 90% of Cu in plasma and performs ferroxidase, antioxidant and amine oxidase activity. Cu and Zn, as trace elements, have been recognized to play an important role as cofactors of SOD. The study presents(More)
UNLABELLED The relationship between hyperglycemia and oxidative stress in diabetes is well known, but the influence of metabolic disturbances recognized as prediabetes, in elderly patients especially, awaits for an explanation. METHODS 52 elderly persons (65 years old and older) with no acute or severe chronic disorders were assessed: waist circumference(More)
OBJECTIVE Onconeuronal antibodies are important diagnostic tool in patients with suspicion of paraneoplastic neurological syndromes (PNS). However, their role in PNS pathophysiology and specificity for particular neurological manifestation remains unclear. The aim of this study was to evaluate onconeuronal and antineuronal antibodies in patients with(More)
BACKGROUND The severity of neurological deficits arising from ischemic stroke may be related to serum redox homeostasis. The aim of this study was to estimate the effect of serum paraoxonase (PON), arylesterase (ARE) activities and conjugated dienes (CD) on patient outcome during a 1-year follow-up period. METHODS The study included 468 consecutive(More)
INTRODUCTION Obesity-related disturbances are considered to be risk factors for cardiovascular disease (CVD). Chromium is shown to improve carbohydrate and lipid metabolism. Conflicting data on effects of chromium supplementation in humans are published. The aim of the study was to assess the concentrations of serum chromium during the 75-g oral glucose(More)
