Receptor for advanced glycation end‐products: Biological significance and imaging applications
PublikacjaThe receptor for advanced glycation end-products (RAGE or AGER) is a transmembrane, immunoglobulin-like receptor that, due to its multiple isoform structures, binds to a diverse range of endo- and exogenous ligands. RAGE activation caused by the ligand binding initiates a cascade of complex pathways associated with producing free radicals, such as reactive nitric oxide and oxygen species, cell proliferation, and immunoinflammatory...

The influence of selenium addition during seeds' germination on the biological properties of obtained sprouts
PublikacjaSelenium plays a vital role in human body, because in the form of aminoacids (Se-methionine, Se-cysteine) it is found in the active centres of over 25 enzymes, including those regarded as 'cytoprotective'. Unfortunatelly, its daily intake in Poland and other European countries is lower than predicted by dietary recommendations. The consequences of selenium deficiency in diet might be severe, including higher susceptibility to cardio-vascular...

The relationship between standard reduction potentials of catechins and biological activities involved in redox control
PublikacjaRedox homeostasis involves factors that ensure proper function of cells. The excess reactive oxygen species (ROS) leads to oxidative stress and increased risk of oxidative damage to cellular components. In contrast, upon reductive stress, insufficient ROS abundance may result in faulty cell signalling. It may be expected that dietary antioxidants, depending on their standard reduction potentials (E°), will affect both scenarios....
