The role of the mast cell in pigmentation disorders

Pigment International, 2021
The mast cell is a critical mediator of the inflammatory response by secreting histamine. While histamine is currently not regarded as a melanogen, recent studies have shown histamine release to induce melanogenesis, melanocyte proliferation and ...

Upcycling Keratin‐Based Textile Waste Into High‐Performance Hybrid Fibers Via Tuning the Interfacial Interactions

Advanced Functional Materials, EarlyView.
Keratin recovered from animal‐hair textile waste is fractionated and blended with cellulose to produce continuously spun hybrid fibers. Selecting the high‐molecular‐weight keratin fraction enables 30 wt.% keratin incorporation while maintaining high strength in dry and wet states.

Ionic Gating of Liquid‐Crystal‐Like Pteridine Assemblies Enables Tunable Light Scattering

Advanced Materials, EarlyView.
Tunable optical properties emerge through developmentally regulated ionic gating, which transforms disordered, ultraviolet (UV)‐absorbing organelles into concentrically ordered, liquid‐crystal‐like light scatterers. By integrating analyses of pteridine composition, potassium‐dependent assembly, hierarchical ultrastructure, and optical behavior, the ...

Multi‐Biomimetic Structural Colors Inspired by Pearls and Bird Feathers

Advanced Materials, EarlyView.
A dual‐biomimetic strategy mimicking pearls and bird feathers is proposed to construct full‐gamut structural colors. By integrating a non‐strictly periodic inorganic multilayer architecture with tunable light absorbers, this facile approach circumvents the complex fabrication of traditional 1D photonic crystals, offering immense potential for cosmetics,

Molecular insights into skin pigmentation: Unraveling the role of key genes and miRNAs in melanogenesis [PDF]

Journal of Clinical and Basic Research
Human skin pigmentation is a complex phenotype governed by an interplay of genetic, biochemical, and physiological factors. Melanogenesis involves tightly regulated enzymatic pathways that control the balance between eumelanin and pheomelanin synthesis ...

Inverse Design of Nanoparticulate Materials

Advanced Materials, EarlyView.
Inverse design shifts nanomaterial development from empirical trial‐and‐error to predictive model‐driven strategies. It can rely on knowledge‐based, data‐based, or hybrid process and property functions. This perspective article provides a practical framework for applying inverse design based on instructive examples. It discusses which modeling approach
