Hydrogel‐Based Smart Materials for Wound Healing and Sensing

Aggregate, EarlyView.
The graphical abstract illustrates the role of hydrogel‐based flexible materials in advancing biomedical applications, including wound healing, point‐of‐care diagnostics, smart patches, and wearable devices. Hydrogels are particularly promising in modern wound care due to their high‐water content, flexibility, and biocompatibility.

Biochemistry and biosynthesis of insect pigments

European Journal of Entomology, 2014
The functional role and commercial importance of insect pigments have been studied for well over a century. They are classified into those synthesized by insects, which include anthraquinones, aphins, pterins, tetrapyrroles, ommochromes, melanins and ...

THYROID AND GONAD AS FACTORS IN THE PRODUCTION OF PLUMAGE MELANINS IN THE DOMESTIC FOWL

, 1927
The results of thyroid feeding on five breeds of domestic fowl are recorded. They vary with dosage and with sex. When the daily ration is compatible with good health, the males of pigmented breeds, both normal and castrated, tend to darken conspicuously ...

Solving the Amyloid Paradox: Unveiling the Complex Pathogenicity of Amyloid Fibrils

Aggregate, EarlyView.
This review addresses the gap between strong evidence for the involvement of amyloid fibrils in neurodegeneration and the failure of anti‐amyloid therapies, a phenomenon herein termed the “amyloid paradox.” To address this paradox, we provide a comprehensive summary of the current understanding of fibrils' pathogenic properties and mechanisms ...

Melanin and Melanin-Like Hybrid Materials in Regenerative Medicine

Nanomaterials, 2020
Melanins are a group of dark insoluble pigments found widespread in nature. In mammals, the brown-black eumelanins and the reddish-yellow pheomelanins are the main determinants of skin, hair, and eye pigmentation and play a significant role in ...

Inhibitory effect of enzymatic browning products on trypsin activity [PDF]

, 2011
The aim of this piece of work was to assay if the melanins synthesized from  Agaricus bisporus polyphenol oxidase and one of its main substrates (L-tyrosine) act as trypsininhibitors, and therefore may have a toxic effect on protein digestion.

Does the abiotic environment influence the distribution of flower and fruit colors?

American Journal of Botany, EarlyView.
Abstract Premise Color in flowers and fruits carries multiple functions, from attracting animal partners (pollinators, dispersers) to mitigating environmental stress (cold, drought, UV‐B). With research historically focusing on biotic interactions as selective agents, however, it remains unclear whether abiotic stressors impact flower and fruit colors ...
