Pigment Melanin: Pattern for Iris Recognition
, 2009 Recognition of iris based on Visible Light (VL) imaging is a difficult problem because of the light reflection from the cornea. Nonetheless, pigment melanin provides a rich feature source in VL, unavailable in Near-Infrared (NIR) imaging.

Gentle Label‐Free Nonlinear Optical Imaging Relaxes Linear‐Absorption‐Mediated Triplet
Advanced Science, EarlyView.The phototoxicity in nonlinear optical microscopy arises mainly from linear absorption of intrinsic biomolecules rather than nonlinear absorption. This mechanism is supported by a reproducible phototoxicity assay based on widely available chicken breast.

Pigmented melanoma cell migration study on murine syngeneic B16F10 melanoma cells or tissue transplantation models [PDF]
, 2019 Melanoma is a lethal form of skin cancer with poor prognosis, especially due to the early metastatic feature. Recent studies have shown that the melanin pigment influences the nanomechanical properties and, therefore, the metastatic behavior of the ...

Homeostasis of Gut Microbiota Protects against Susceptibility to Fungal Pneumonia
Advanced Science, EarlyView.Fungal pneumonia induces inflammation, shown by heightened IL‐6, IL‐1β, TNF‐α levels and a growth in Staphylococcus in the alveolar flora. The gut microbiota, acting through the gut‐lung axis via blood, impacts fungal pneumonia susceptibility by altering lung metabolism and inflammatory responses.

Angewandte Chemie, EarlyView.Cryptococcus neoformans cell wall α‐1,3‐glucans as dual anchors for melanin and capsule: Solid‐state NMR of intact C. neoformans cells reveals five forms of α‐1,3‐glucans that structurally bridge melanin and capsule layers. These polysaccharides interact with chitin, chitosan, and β‐glucans to create a molecular scaffold that underlies virulence and ...

Eumelanin-based coloration and fitness parameters in birds: a meta-analysis [PDF]
, 2010 Although melanin is the most common pigment in animal integuments, the adaptive function of variation in melanin-based coloration remains poorly understood. The individual fitness returns associated with melanin pigments can be variable across species as

Label‐Free 3D Photoacoustic Imaging of Tumor Organoids for Volumetric Drug Screening
Advanced Science, EarlyView.A label‐free organoid photoacoustic imaging (LFOPI) system is developed for precise volumetric drug screening evaluation. As a proof of concept, LFOPI's performance in chemotherapy and immunotherapy drug screening assays are further evaluated. The LFOPI offers unique non‐invasive, label‐free capabilities for tumor organoids, and contributes to the ...
