Extreme environmental pollution such as that found in the highly industrialized Silesian region of Poland has been associated with increased risk of cancer and adverse reproductive outcomes. Among the most prevalent carcinogenic and mutagenic air pollutants in Silesia are the polycyclic aromatic hydrocarbons (PAH) which are largely produced by industrial(More)
Sensitivity to bleomycin was investigated in lymphocytes collected from three groups of males: 30 occupationally exposed cokery workers, 38 environmentally exposed Silesian citizen and 35 rural inhabitants. The data were analyzed at both the individual and group levels. The first analysis has revealed a substantial interindividual variability in the level(More)
Germline mutations in the BRCA1 or BRCA2 genes predispose their carriers to breast or/and ovary cancers during their lifetime. The most frequent mutations: 5382insC, 185delAG, C61G and 4153delA in BRCA1, and 6174delT and 9631delC in BRCA2 were studied in a group of 148 probands admitted for genetic counseling, using allele-specific amplification (ASA) PCR(More)
Exposure of Chinese hamster V79 cells to extracts of airborne pollutants induced formation of multipolar or incomplete mitotic spindles. To find out whether overexpression of the HSP70 chaperone protein could protect spindles against airborne toxins we constructed V79 cells stably transfected with an expression vector containing rat heat-inducible hsp70.1(More)
The present report is a follow-up to our previous molecular epidemiology studies on DNA damage in residents of the industrial region of Upper Silesia. The study was designed to focus on environmental exposure to airborne pollutants; other exposures or confounding factors (e.g. smoking status and age) were eliminated. A Silesian population consisting of 67(More)
Sister chromatid exchanges (SCE) and high-frequency cells (HFC) were measured in peripheral blood lymphocytes from men environmentally and occupationally exposed to a mixture of ambient air pollutants. The environmentally exposed individuals were inhabitants of the industrial region of Upper Silesia; those occupationally exposed were Silesian cokery or(More)
The level of sister-chromatid exchanges (SCE), high-frequency cells (HFC), chromosomal aberrations (CA) as well as the proliferation rate index (PRI) were measured in peripheral blood lymphocytes from three groups of volunteers. The environmentally exposed donors were residents from the vicinity of a coke factory; the occupationally exposed persons were(More)
The levels of sister chromatid exchanges (SCE), high-frequency cells (HFC) and chromosomal aberrations (CA) were studied in lymphocytes of Silesian women environmentally exposed to ambient air pollutants. Inhabitants of a less polluted but similarly urbanized area, in a rural region of Poland, served as controls. The study population was selected to(More)
Sequential elution solvent chromatography (SESC) developed by Farcasiu for characterization of coal liquids was used for the fractionation of benzene extracts of airborne particulate pollutants. Mutagenic and clastogenic activity of SESC fractions was determined by the Salmonella/microsome test and the assay for V79 cell chromosomal aberrations (CAs),(More)
1. Sequences complementary to rRNA in rat DNA amount to 0.04% which corresponds to about 300 rRNA genes per haploid genome. 2. Purified DNA-rRNA hybrids had a DNA: rRNA weight ratio of about 1.1:1. Their melting temperature estimated on hydroxyapatite column was 75-80 degrees C. In CsCl gradients hybrids banded at 1.728 g/cm3 as compared to 1.699 g/cm3 for(More)
