In the presence of Ni(II)‐ions selective hydrolysis of the peptides containing the –SXH– or –TXH– motif was observed. Since the side chain of histidine serves as the metal ion binding site for many native proteins, and very often histidine is present in a –SXH– or –TXH– sequence, to study the complex formation and hydrolytic processes in presence of nickel(II) ion four peptides were synthesised: Ac‐SKHM‐NH2, A3SSH‐NH2, A4SSH‐NH2, AAAeKSH‐NH2. The Ni(II)‐induced hydrolysis of Ac‐SKHM‐NH2 peptide occurs rapidly in alkaline medium already at room temperature. In two peptides containing –SSH– sequence on the C‐termini, the N‐terminal part is the major binding site for the nickel(II) ion, but the formation of dinuclear complexes was also observed. In the [Ni2LH–6]2– complex of hexapeptide, the coordination sphere of the metal ions is saturated with deprotonated Ser‐O–, which does not result in hydrolysis of the peptide. For A4SSH‐NH2, both Ni(II) ions fulfill the conditions for hydrolysis, which was confirmed by HPLC analyses at pH ~ 8.2 and 25 °C.}, year = {2024}, eissn = {1439-7633}, orcid-numbers = {Várnagy, Katalin/0000-0003-0846-4689} } @article{MTMT:35121752, title = {A systematic review of STEM teaching-learning methods and activities in early childhood}, url = {https://m2.mtmt.hu/api/publication/35121752}, author = {Revákné Markóczi, Ibolya and Csernoch, Mária and Czimre, Klára and Dávid, Ágnes and Tóth, Beáta Kosztin and Malmos, Edina and Sütő, Éva and Kurucz, Dóra}, doi = {10.29333/ejmste/14779}, journal-iso = {EURASIA J MATH SCI T}, journal = {EURASIA JOURNAL OF MATHEMATICS SCIENCE AND TECHNOLOGY EDUCATION}, volume = {20}, unique-id = {35121752}, issn = {1305-8215}, abstract = {This study aims to help educators and researchers to understand the pedagogical practice of STEM in early childhood and its impact.

Our study aimed to assess the accumulation of these elements across species with varying diets and habitat preferences, as well as their potential role in biomonitoring efforts. The Ca, K, Mg, Na, Cd, Cr, Cu, Fe, Mn, Pb, Sr, and Zn concentration was analyzed in muscle, gills, and liver using MP-AES. The muscle and gill concentrations of Cr, Cu, Fe, and Zn increased with trophic level. At the same time, several differences were found among the trace element patterns related to habitat preferences. The trace elements, including Cd, Pb, and Zn, which exceeded threshold concentrations in the water, exhibited higher accumulations mainly in the muscle and gills of the pelagic chub. Furthermore, the elevated concentrations of trace elements in sediments (Cr, Cu, Mn) demonstrated higher accumulation in the benthic nase and barbel. Our findings show habitat preference as a key factor in juvenile bioindicator capability, advocating for the simultaneous use of pelagic and benthic juveniles to assess water and sediment pollution status.}, keywords = {fish; pollution; Heavy metals; Trophic level; habitat preference}, year = {2024}, eissn = {2045-2322}, orcid-numbers = {Nyeste, Krisztián József/0000-0002-9848-7608; Uzochukwu, Ifeanyi Emmanuel/0000-0003-2424-0327; Somogyi, Dóra/0000-0003-2486-1414; Antal, László/0000-0001-9831-1429} }
