Solidago canadensis L. (SC) (Canadian goldenrod) is a dangerous plant invader in Europe, which suppress the indigenous flora. Essential oils (EOs) are considered biological control agents. GC-MS analysis for identification of main components was conducted and the potential phytotoxicity of six EOs were also evaluated. Limonene and β-thujone were dominant components in Salvia officinalis L., menthone and menthol in Mentha × piperita L., carvacrol in Origanum vulgare L., estragole/anisole and anethole in Foeniculum vulgare Mill., limonene and carvone in Anethum graveolens L., and anethole in Pimpinella anisum L. Along with EOs, anethole, anisole, camphor, carvone, estragole, limonene, menthol, menthone, thujone and thymol were used independently to evaluate phytotoxic effect against Canadian goldenrod seed germination. A significant inhibitory effect was registered for origanum (1.250 µg.ml−1). The influence of single components was significant. The highest phytotoxic activity was registered with anethole and estragole. Phenolic compounds were the inhibitoriest, followed by oxygenated and hydrocarbon monoterpenes. [ABSTRACT FROM AUTHOR]

Mentha × piperita L. (peppermint) is one of the most economically important aromatic plants. The plant and its essential oil are used in medicine, cosmetics and food industry. Peppermint was obtained by crossing M. aquatica and M. spicata , and the industry is searching for new cultivars, with high biomass productivity and high content of essential oil (EO), with menthol and menthone as main components. A method of selection of clones and lines was used for breeding of the new cultivar ʻKristinkaʼ in East Slovakia. The present work describes the evaluation of the biomass production and qualitative and quantitative parameters of the essential oil during the breeding process of this cultivar. Average biomass production was 4.6 kg m 2 , average content of EO was 1.38%, with menthol and menthone amounts of 69.3 and 12.5%, respectively. [ABSTRACT FROM AUTHOR]

Two selected mutant lines, C26 and C82, with highly significant 1000-seed weight and generated through irradiation treatment of Amaranthus cruentus L. 'Ficha', were evaluated and compared to an original nontreated control and reference variety Aztec. The phenotypic traits and biochemical properties of the amaranth seeds were studied. Comparable values for crude protein content, albumins, and globulins fractions and overall coefficients of nutritional quality were found in the evaluated samples. However, C26 showed significantly lower concentrations of celiac-related prolamins and glutelins in comparison with the control sample. Both of the mutagenesis-derived lines showed consistently superior performance of 1000-seed weight across two tested environments during a multiyear evaluation. C82 showed seed weight advantage over control seeds of Ficha and reference variety Aztec and it was released as a new amaranth variety named Pribina in 2013. [ABSTRACT FROM AUTHOR]

The article discusses the effects of polycyclic aromatic hydrocarbon (PAH) exposure on coke oven workers in Eastern Slovakia, revealing a significant increase in chromosomal aberrations and gaps. It emphasizes the potential mutagenic and carcinogenic risks associated with PAH exposure in industrial settings, and it emphasizes the importance of cytogenetic analysis for preventive and public health interventions.

The article discusses fingerprint patterns as a predictive tool for type 2 diabetes mellitus (T2DM) diagnosis. It emphasizes early detection and prevention. It suggests dermatoglyphic analysis as a screening method for T2DM risk assessment. It highlights the global prevalence of T2DM and the need for innovative methods to identify early biomarkers and enhance prevention strategies.

The article discusses the prevalence of COVID-19 antibodies among Saint. Jacob Hospital employees, revealing variations across different departments. It reports that a significant percentage tested positive for Immunoglobulin G (IgG) antibodies, indicating past infection or vaccination, with higher levels in departments with direct patient contact. It highlights the importance of antibody detection in evaluating individual and population immunity.
