The aim of this study was to find correlations between folate and vitamin B₁₂ on baseline damage in white blood cells and their association with smoking, alcohol consumption and ageing. Thirty-six healthy vitamin non-deficient male subjects were selected in a randomized study. Comet assay (SCGE) and micronucleus (MN) assay were used as biomarkers of DNA(More)
AIM To evaluate chromosome aberration and fluorescent in situ hybridization (FISH) assays as a method to estimate of health risk, we monitored 9 male subjects occupationally exposed to low doses of both ionizing radiation and ultrasound during a period of over 3 years. METHODS Sampling was performed at 6-month intervals during a three-year period. First(More)
The decrease of unstable chromosomal damages (dicentrics, rings and acentric fragments) was observed in circulating peripheral blood lymphocytes after exposure to ionizing radiation. The study comprised 100 subjects, all medical staff occupationally exposed to X-rays, who were re-examined for unstable chromosomal aberrations after 3 months (12 subjects), 6(More)
Individual sensitivity to ionising radiation (IR) is the result of interaction between exposure, DNA damage, and its repair, which is why polymorphisms in DNA repair genes could play an important role. We examined the association between DNA damage, expressed as micronuclei (MNi), nuclear buds (NBs), and nucleoplasmic bridges (NPBs) and single nucleotide(More)
Occupational exposure to anaesthetic gases is associated with various adverse health effects. Genetic material is a sensitive target of numerous harmful agents. The aim of this study was to examine whether chromosomal damage could serve to indicate exposure to anaesthetics. Twenty-eight anaesthesiologists, 16 technicians, and 32 control subjects were(More)
Irinotecan is a topoisomerase I interactive agent, widely used in the treatment of metastatic colorectal cancer. The genotoxic effects of the maximum single dose (18 microg mL-1), recommended monotherapy dose (9 microg mL-1), and recommended combined therapy dose (4.5 microg mL-1) of irinotecan were studied on V79 cells using the comet assay, chromosome(More)
Medical staff is an occupational group exposed to different agents suspected to induce genetic damage. Among them ionising radiation is the most studied. Cytogenetic analysis of human chromosomes in peripheral lymphocytes allows direct detection of mutation in somatic cells. This study investigated the cytogenetic effects of low-level ionising x-radiation(More)
The receptors for rabies virus on the neuron membranes are polysialogangliosides arranged in multicomponent gelate structures. The impulse conductivity at the synapse membranes also depends on the interactions between negatively charged sialic acid from the oligosaccharide parts of gangliosides and positively charged Ca ions. From individual brain regions(More)
