The aim of the study was to determine if there is a relationship between attitudes toward doping and achievement goal orientations of athletes. Questionnaires from 830 athletes (including 263 females) were obtained. Athletes declared moderately positive attitudes, with attitude toward anti-doping controls as the strongest and attitude toward sanctions as(More)
TGF-beta is an important mediator of cell growth, differentiation, and proliferation and plays a significant role in both normal and pathological corneal tissue. However, the quantitative relations between TGF-beta1, -beta2 and -beta3 isoforms in human cornea still remain unclear. Therefore, the aim of this study was to determine the gene expression profile(More)
PURPOSE Cancerogenesis is a multistage process controlled by many cytokines, including growth factors. The aim of the study was the comparison of transcriptional activity of transforming growth factor beta (TGF-beta) genes in laryngeal squamous cell carcinomas and adjacent nonneoplastic tissues. MATERIALS AND METHODS Tissues samples were obtained from 32(More)
Inositol hexaphosphate (IP6, phytic acid) is a naturally occurring carbohydrate abundantly present in high-fiber diets and it is also contained in almost all mammalian cells. It plays an important role in signal transduction, cell proliferation and differentiation. Some natural substances have been shown to elicit an impact on the expression of TNF-alpha(More)
Fifteen (soil and intestinal) strains of Desulfovibrio desulfuricans species were typed by PCR method with the use of primers specific for repetitive extragenic palindromic (REP) and enterobacterial repetitive intergenic consensus (ERIC) sequences. As a result, characteristic DNA fingerprints for the strains were obtained. Moreover, the genetic profiles(More)
The aim of this study was to determine whether Desulfovibrio desulfuricans-derived LPS stimulate the release of IL-6 and IL-8 from ECs and the expression of their adhesion molecules at the transcriptional level. Confluent monolayers of HUVEC were incubated in the absence or presence of 20 microg/ml and 60 microg/ml LPSs derived from the DdT and DdA(More)
The objective of the study is to assess the external and internal exposures to aromatic hydrocarbons in the tar and oil naphthalene distillation processes at a coke plant. 69 workers engaged as operators in tar and oil naphthalene distillation processes and 25 non-exposed subjects were examined. Personal analyses of the benzene, toluene, xylene isomers,(More)
The content of endogenous melanin in white Balb c and black C-57 Bl. mice affected Zn2+ and Co2+ accumulation, elimination and distribution following intraperitoneal administration of these ions. Elimination of Co2+ ions was significantly greater in white mice than in black mice. Accumulation of Zn2+ was higher than that of Co2+ and did not depend on(More)
The objective of this study was to determine the expression of transforming growth factor-beta1 messenger RNA (TGF-beta1 mRNA) and the expression of mRNA for TGF-beta receptors (TGF-beta Rs mRNA) in whole peripheral blood of consecutive (treated from several months to several years) systemic lupus erythematosus (SLE) patients (21 women). A further aim of(More)
Mechanisms of action at the cellular level of a variety of drugs and xenobiotics may be assessed using Chlorella vulgaris cells. Synchronous culture, which consists of cells at the same phase of development, provides the most convenient model for studying processes at the cellular level. Stability of metabolic activity of synchronously growing cells is(More)
