The epidemiological association between cancer and exposure to ambient air pollution particles (particles with a 50% cut-off aerodynamic diameter of 10 microm (PM(10))) has been related to the ability of PM(10) and its constituent nanoparticles (NPs) to cause reactive oxidative species (ROS)-driven DNA damage. However, there are no data on the molecular(More)
The aim of the study was to assess whether cerebrospinal fluid tau protein is associated with cognitive changes in children with acute lymphoblastic leukemia (ALL). Examination of 38 ALL patients revealed a statistically significant increase in tau protein on treatment day 59 and at two points during consolidation phase. Cognitive functioning was examined(More)
Ethanol has been previously shown to reduce the unsaturated fatty acid content of cell membranes. It is not known, however, if the observed deleterious effects are due to ethanol itself or its metabolite, acetaldehyde. The present study was undertaken to assess the effect of acetaldehyde produced from ethanol by alcohol-deyhdrogenase-transfected Chinese(More)
We demonstrated opposite presence of mycobacterial heat shock proteins (Mtb-hsp) 70 kDa, 65 kDa, 16 kDa in sera and lymph nodes in sarcoidosis (SA). Higher occurrence of serum Mtb-hsp70 than Mtb-hsp 65 and Mtb-hsp 16 could be caused by sequestration of Mtb-hsp 65 and Mtb-hsp 16 in circulating immune complexes (CIs). It is possible that in genetically(More)
Because of the important role of glial cells in brain maturation and reports on their delayed proliferation following ethanol exposure, it was considered of interest to investigate the mechanism of ethanol action on these cells. Biochemical parameters related to the apoptotic and necrotic processes in astroglial cells exposed for 1 week to 50 and 100 mM(More)
The effect of paternal alcohol exposure on neurochemical and behavioral parameters was investigated using as a model system glial cells derived from newborn rat brain and cultured for 4 weeks. The total brain neurochemical parameters from rats born to mothers sired by an alcohol treated father were also investigated. Enzymatic markers of nerve cell(More)
cAMP responsive element binding protein (CREB) plays an important role in transcriptional machinery. CREB signaling is altered in patients with asthma. However, the role of CREB in chronic obstructive pulmonary disease (COPD) is less clear. In the present study we assessed changes in subcellular CREB distribution and activation (CREB-P) in 35 stable COPD(More)
The effect of acetaldehyde on astrocytes have been investigated because not only do they play an important role in brain maturation but also recent reports have shown their delayed proliferation following both 'in vivo' and 'in vitro' ethanol exposure. Biochemical parameters related to apoptotic and necrotic processes were examined in primary cultures of(More)
The aim of the study was to investigate the levels of cerebrospinal fluid (CSF) cytokines during chemotherapy of acute lymphoblastic leukaemia (ALL). Examination of 12 ALL child (6 boys and 6 girls) patients evidenced significant increases in interleukin-6 (IL-6) and monocyte chemotactic protein-1 (MCP-1) after induction treatment and significant increases(More)
Beneficial effects of St. John's wort (Hypericum perforatum) in the treatment of stress-evoked memory impairment were recently described. In this study, we tested a hypothesis that St. John's wort alleviates stress- and corticosterone-related memory impairments by restoring levels of synaptic plasticity proteins: neuromoduline (GAP-43) and synaptophysin(More)
