Graphical abstract Schematic representation of the enzyme mimic activities of 316ss wire mesh for the colorimetric detection of hydrogen peroxide H 2 O 2 and GSH with a superior reusability for more than 25 cycles
However, its reliability in distinguishing the degree of corneal thinning could be further improved with appropriate illumination modifications
This revealed its antioxidative role in reducing oxidative stress and contributing to the inhibition of melanin synthesis by modulating the GSH redox balance ( In vitro , PYC exhibits antioxidant effects during adipogenesis by downregulating the mRNA expression of pro-oxidant enzymes, such as nicotinamide adenine dinucleotide phosphate hydrogen oxidase 4 and glucose-6-phosphate dehydrogenase, while simultaneously upregulating antioxidant enzymes, including Cu/Zn-SOD, Mn-SOD, GPx, and GSH reductase ( ex vivo studies show that PYC acts synergistically with lutein to reduce oxidative stress in porcine retinal homogenates ( In a study using Escherichia coli mutants, PYC induced the expression of key antioxidant enzymes such as MnSOD and CuZnSOD, particularly under oxidative stress, suggesting a potential antioxidative role ( Similarly, PYC mitigated oxidative stress and inflammation induced by titanium dioxide nanoparticles in both murine lung tissue and human airway epithelial cells ( In a randomized clinical trial involving pediatric patients with attention deficit hyperactivity disorder, PYC treatment produced a modest increase in catalase activity, suggesting potential antioxidant effects (Figure 1) in diverse contexts and experimental models

Engaging in physical activity, both intensive movement improvement and increased muscle strength do not occur without side effects, resulting in accelerated tissue wear, especially in professional athletes, where excessive use affects areas where tissues are genetically less valuable and prone to frequently occurring, cumulative micro-injuries
