BACKGROUND AND AIMS Much of our understanding of the genetic control of meiosis has come from recent studies of model organisms, which have given us valuable insights into processes such as recombination and the synapsis of chromosomes. The challenge now is to determine to what extent these models are representative of other groups of organisms, and to what(More)
Authors compared the incidence of chromosomal aberrations (CAs) of workers occupationally exposed to cytostatics (group EXP1) or anaesthetics (group EXP2) in relationship to polymorphism of GSTM1, GSTP1 and GSTT1 genes. The cytogenetic analysis for chromosomal aberrations frequency and for polymorphisms of genes the PCR and PCR-RFLP method were used.(More)
OBJECTIVES Structural chromosomal aberrations in blood lymphocytes represent a biomarker for cellular damage caused by genotoxic carcinogens and are an indicator of increased cancer risk. We evaluated the association between frequencies of total chromosomal aberrations, chromatid- and chromosome-type aberrations, and occupational exposures to volatile(More)
Electrolytic production of aluminium in former Czechoslovakia started in the year 1953 in the Žiar valley in the central Slovakia. However, till 1995 the hygienic conditions for health protection were not met in the factory. It underwent a reconstruction afterwards.The authors demonstrate cases of occupational skeletal fluorosis (currently rare in Europe)(More)
We evaluated chromosomal aberrations in lymphocytes of 177 workers exposed to xenobiotics in a tire plant and in 172 controls, in relation to their genetic background. Nine polymorphisms in genes encoding biotransformation enzymes and nine polymorphisms in genes involved in main DNA repair pathways were investigated for possible modulation of chromosomal(More)
Authors evaluated the incidence of total chromosomal aberrations (CA) and their types - chromatid-type (CTA) and chromosome-type (CSA) in peripheral blood lymphocytes from 72 oncologic unit's workers occupationally exposed to cytostatics in relationship to polymorphisms of DNA repair genes XPD, XPG and XPC. The cytogenetic analysis was used for(More)
In December 2011, a major revision of GOLD 2011 guidelines was published based on the evidence-based medicine. The goal of GOLD 2011 is to determine the severity of the disease, its impact on the patient's health, and the risk of future events; all of which eventually guide therapy. A combined COPD assessment according to GOLD 2011 considers the patient's(More)
STUDY OBJECTIVE To conduct a retrospective 15-year study to monitor trends in the number of employees at risk for occupational tuberculosis (TB) (levels III and IV) in the Slovak Republic, and in particular in the sector of economic activities Q (health care and social assistance). Furthermore, to analyze reported cases of occupational TB and to compare the(More)
Human cancers are often associated with numerical and structural chromosomal instability. Structural chromosomal aberrations (CAs) in peripheral blood lymphocytes (PBL) arise as consequences of direct DNA damage or due to replication on a damaged DNA template. In both cases, DNA repair is critical and inter-individual differences in its capacity are(More)
