Label‐Free 3D Photoacoustic Imaging of Tumor Organoids for Volumetric Drug Screening

open access: yesAdvanced 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 ...

The pbrB gene encodes a laccase required for DHN-melanin synthesis in conidia of Talaromyces (Penicillium) marneffei. [PDF]

open access: yesPLoS ONE, 2015
Talaromyces marneffei (Basionym: Penicillium marneffei) is a significant opportunistic fungal pathogen in patients infected with human immunodeficiency virus in Southeast Asia. T. marneffei cells have been shown to become melanized in vivo.

An Anisotropic Gold‐Palladium Heterostructured Nanosystem for Synergistically Overcoming Radioresistance and Enhancing Melanoma Radioimmunotherapy

open access: yesAdvanced Science, EarlyView.
A multifunctional anisotropic Au‐Pd heterostructured nanosystem is developed that incorporates a plasmonically enhanced Au‐Pd core, with a shell composed of a biodegradable, Mn‐doped targeting peptide. The nanosystem integrates photothermal, radiotherapeutic, and immunomodulatory functions.

GENES DETERMINING THE SYNTHESIS OF LAVONOID AND MELANIN PIGMENTS IN BARLEY

open access: yesВавиловский журнал генетики и селекции, 2018
In addition to the green color caused by chlorophyll, grain and vegetative organs of barley can be colored by compounds of phenolic nature, such as melanins and lavonoids, which include anthocyanins, proanthocyanidins. Due to the wide biological activity

Structural Variations Associated with Adaptation and Coat Color in Qinghai‐Tibetan Plateau Cattle

open access: yesAdvanced Science, EarlyView.
This study reveals the landscape of structural variants in Qinghai‐Tibetan Plateau cattle through long‐read sequencing. Discoveries include metabolic and oxygen‐regulation gene variants, along with a 2‐Mb KIT‐containing inversion and translocations responsible for cattle gray coat. These findings highlight the significant role of structural variants in

Condition-dependence of pheomelanin-based coloration in nuthatches Sitta europaea suggests a detoxifying function: implications for the evolution of juvenile plumage patterns [PDF]

open access: yes, 2017
Adult-like juvenile plumage patterns often signal genotypic quality to parents. During adulthood, the same patterns often signal quality to mates.
