Light-Photoreceptors and Proteins Related to Monilinia laxa Photoresponses

Journal of Fungi, 2021
Light represents a ubiquitous source of information for organisms to evaluate their environment. The influence of light on colony growth and conidiation was determined for three Monilinia laxa isolates. The highest mycelial growth rate was observed under

Tumor microenvironment responsive and nanozyme‐catalyzed photodynamic therapy via lysosome‐localized copper‐doped carbon dots

Responsive Materials, EarlyView.
The lysosome‐localized copper‐doped carbon dots (Cu‐MLCDs) leverage the high expression of glutathione (GSH)/H2O2 in the tumor microenvironment to achieve fluorescence reactivation enhancement. Through its multi‐nanozyme activities (glutathione peroxidase, peroxidase, and catalase), this nanoplatform relieves hypoxia, depletes GSH, and synergistically ...

Effects of Substituents on the Photophysical/Photobiological Properties of Mono-Substituted Corroles

Molecules, 2023
The trans-A2B-corrole series was prepared starting with 5-(pentafluorophenyl)dipyrromethene, which was then reacted with respective aryl-substituted aldehyde by Gryko synthesis. It was further characterized by HRMS and electrochemical methods.

Behavioral response of moose Alces alces to summer heat stress

Wildlife Biology, EarlyView.
Minnesota moose are heat‐stressed during summers, which is adversely impacting their survival. We used both movement and activity data to explore the behavioral responses of Minnesota moose experiencing heat stress, termed ‘hot moose events' or HMEs, to understand how both ambient temperature and available habitat contribute to the ability of these ...

Conductance Mechanisms of Rapidly Desensitizing Cation Channelrhodopsins from Cryptophyte Algae

mBio, 2020
Channelrhodopsins guide algal phototaxis and are widely used as optogenetic probes for control of membrane potential with light. “Bacteriorhodopsin-like” cation channelrhodopsins (BCCRs) from cryptophytes differ in primary structure from other CCRs ...

Metabolic Profiling of Circulating and Tumour‐Infiltrating T Cells Uncovers Bioenergetic Checkpoints Linked With Immune and Clinical Skewing in Melanoma Patients

Immunology, EarlyView.
In this study, we revealed the disturbed metabolic status of circulating and tumour‐infiltrating CD4+ and CD8+ T cells in melanoma patients through targeted metabolomic and lipidomic (on sorted subsets) and at single cell level using the SCENITH method.

Distinct Bleaching Resilience of Photosynthetic Plastid-Bearing Mollusks Under Thermal Stress and High CO2 Conditions

Frontiers in Physiology, 2018
The impact of temperature on photo-symbiotic relationships has been highly studied in the tropical reef-forming corals but overlooked in less charismatic groups such as solar-powered sacoglossan sea slugs. These organisms display one of the most puzzling

Red LED Light Acts on the Mitochondrial Electron Chain of Mammalian Sperm via Light-Time Exposure-Dependent Mechanisms

Cells, 2020
This work analyzes the effects of red LED light on mammalian sperm mitochondrial function, using the pig as an animal model. Liquid-stored pig semen was stimulated with red-light for 1, 5 and 10 min in the presence or absence of oligomycin A, a specific ...

Development of chalcones structure‐related to avobenzone: Photoprotection, photostability, and safety evaluation

Photochemistry and Photobiology, EarlyView.
Scaffold hopping strategy used to develop chalcones structure‐related to the avobenzone tautomer. Positive aspects of 2‐hydroxychalcones are highlighted. Abstract Chalcones are α,β‐unsaturated ketones with extended π‐conjugation, making them promising scaffolds for the development of organic UV filters.
