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

Advanced 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

Boron Difluoride Formazanate Dye With Donor Planarization Engineering for 1060 nm Laser Activated Photothermal Theranostics

Advanced Science, EarlyView.
The donor engineering strategy enhances the planarity of the π‐conjugated molecular framework, thereby promoting stronger intramolecular charge transfer (ICT). This structural refinement in FBDFDPA leads to a pronounced bathochromic shift in absorption from the NIR‐I to the NIR‐II region, enabling effective photothermal therapy (PTT) for tumors within ...

Melanin particles isolated from the fungus Fonsecaea pedrosoi activates the human complement system

Memorias do Instituto Oswaldo Cruz, 2018
BACKGROUND Melanin production has been associated with virulence in various pathogenic fungi, including Fonsecaea pedrosoi, the major etiological agent for chromoblastomycosis, a subcutaneous fungal disease that occurs in South America.

Melanin and Light

Chemistry – A European Journal
AbstractMelanin is responsible, in Nature, for photoprotection, for this reason it is expected to be poorly photoreactive. However, the photo‐reactivity of melanin and related materials is well documented. Here we discuss some relevant recent examples to demonstrate that, indeed, the actual mechanism of interaction of melanin with light is complex and ...

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 ...

Agouti protein, mahogunin, and attractin in pheomelanogenesis and melanoblast-like alteration of melanocytes: a cAMP-independent pathway [PDF]

, 2009
Melanocortin-1 receptor (MC1R) and its ligands, a-melanocyte stimulating hormone (aMSH) and agouti signaling protein (ASIP), regulate switching between eumelanin and pheomelanin synthesis in melanocytes.

Diglycerides of Natural Phenols and Organic Acids for Enhanced Biological Activities

Asian Journal of Organic Chemistry, EarlyView.
Diglycerides of natural organic acids and phenols were synthesized regio‐selectively. Diglycerides are structurally similar to cell membranes and are expected to exhibit cell affinity and permeability. The flexible glycerol linkers allow the diglycerides to exhibit not only the physiological activities of each constituent organic acid but also the ...

Anti-ultraviolet, antibacterial, and biofilm eradication activities against Cutibacterium acnes of melanins and melanin derivatives from Daedaleopsis tricolor and Fomes fomentarius

Frontiers in Microbiology
Fomes fomentarius and Daedaleopsis tricolor produced significant amounts of water-insoluble melanins, and our previous study successfully enhanced their water solubility by arginine modification.

Ionizing radiation changes the electronic properties of melanin and enhances the growth of melanized fungi.

PLoS ONE, 2007
BackgroundMelanin pigments are ubiquitous in nature. Melanized microorganisms are often the dominating species in certain extreme environments, such as soils contaminated with radionuclides, suggesting that the presence of melanin is beneficial in their ...
