The effect of aqueous and ether Chelidonium majus haulms extract on cervical HeLa tumor cells, mammary adenocarcinoma MCF 7 tumor cells and acute lymphoblastic leukemia CEM tumor cells in vitro have been studied. The purpose of this research was to compare the effect of aqueous and ether Chelidonium majus haulms extract on selected tumor cells. Colorimetric MTT assay have been used for the study of the antiproliferative effect of aqueous and ether haulms extract of Chelidonium majus on cell viability in vitro. The results of the experiments have shown the cytotoxic effect of the aqueous and the ether Chelidonium majus haulms extract on the individual tumor cells. The aqueous Chelidonium majus haulms extract was the most effective on CEM cells, it was less effective on MCF 7 cells and it was the least effective on HeLa cells. The ether haulms extract of Chelidonium majus was the most effective at all of studied concentrations on CEM cells and MCF 7 cells in comparison with HeLa cells, where it was significantly effective only at the highest concentration. Aqueous and ether haulms extract of Chelidonium majus tested in vitro indicated their cytotoxic activity. Both haulms extract of Chelidonium majus were more efficient on CEM cells. It is assumed that higher antiproliferative activity of ether haulms extract of Chelidonium majus is the result of higher antiproliferative activity of lipophilic substances. The lipophilic substances pass through membrane and bind to various proteins and change their biological activity.
Roma constitute the largest ethnic minority in Europe and the second largest minority in Slovakia. Their health problems originate mainly from their low socioeconomic status, certain cultural aspects and their health-threatening lifestyle as well as the psycho-social burden arising from poverty and frequent migration. Evaluation of glucose, albumin, triacylglycerol (TAG) and low density lipoprotein cholesterol (LDL-C) concentrations did not reveal any clue about the presumed deteriorated health of the Roma population. Higher proportions of subjects with elevated serum total cholesterol were found in Roma women as compared to both control groups of women (p = 0.027, p = 0.006) and in Roma men as compared to the male control group living in standard conditions. Only the low level of HDL-cholesterol gives a glimpse of their deteriorated health. Significantly lower levels of serum HDL-C were reported in Roma men and women compared to the respondents in both control groups with a p value of p < 0.001. Comparing the ratio of LDL-C/HDL-C yielded significant differences between the number of physiological values in Roma men and men from the control group 1 (p = 0.022) in favour of the control group. When comparing the number of people with physiological values of cholesterols and with worsening TAG parameters at the same time, the increased risk of Roma men compared with men from the control group 1 became evident, with a level of significance of p = 0.023. Evaluation of urine samples pointed to significantly higher concentrations of urinary protein in Roma women compared with women in the control group 1 (p = 0.012).

Combination of viscometry and CD spectrometry made it possible to suggest the existence of a new conformational state of cytochrome c at high temperatures and ionic strengths. The molten globule state of cytochrome c was found at acidic pH in the presence of high concentrations of a salt at 20 °C. A low-cooperative conformational change of the cytochrome c to the unfolded state was observed with increasing temperature. Viscometry is a suitable tool for studies of similar processes in biomacromolecules.
