      research Nitrogen-Boosted H2O2 Production of Arginine-Polyphenol Nanozyme Drives Oxidative Eustress for Hair Regeneration

      November 2025 in “Advanced Science”
      The study introduces a novel polyphenol–amino acid nanozyme (PEAs) that enhances H2O2 production to drive oxidative eustress, promoting hair regeneration. By combining epigallocatechin gallate (EGCG) and L-arginine (L-Arg), the nanozyme facilitates controlled H2O2 generation, which is crucial for activating hair follicles. In a mouse model of telogen effluvium, this controlled delivery of H2O2 upregulates Wnt/β-catenin and downregulates Ca2+/calcineurin/NFAT pathways, leading to significant follicle activation. This approach offers a non-pharmacological, safe, and effective strategy for treating alopecia by harnessing beneficial oxidative stress for tissue renewal.

      Women generally handle heart enlargement better than men, but it's riskier for them if it occurs; hormones like estrogen offer some protection.
