Unique Cl– pump rhodopsin with close similarity to H+ pump rhodopsin

Biophysics and Physicobiology, 2022
Microbial rhodopsin is a ubiquitous membrane protein in unicellular microorganisms. Similar to animal rhodopsin, this protein consists of seven transmembrane helices and the chromophore retinal.

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

European Society of Contact Dermatitis Guideline for Diagnostic Patch Testing—Recommendations on Best Practice (Update 2026)

Contact Dermatitis, EarlyView.
ABSTRACT The present guideline updates the initial ESCD patch testing guideline, summarizing all aspects of patch testing for the diagnosis of contact allergy in patients suspected of suffering, or having been suffering, from allergic contact dermatitis or other delayed‐type hypersensitivity skin and mucosal conditions. Sections with brief descriptions

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.

Systemic effects of sunlight: 10‐year review of cardiovascular, infection and cancer outcomes

Journal of the European Academy of Dermatology and Venereology, EarlyView.
This review highlights the systemic effects of sunlight and ultraviolet radiation. While UV radiation exposure has known cutaneous risks including photoaging and skin cancer, evidence suggests potential associations with reduced all‐cause mortality, improved infectious disease outcomes and reduced blood pressure.

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 ...

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.

Acid‐ and Nucleophile‐Gated Photoisomerization of Phosphaindirubin

Angewandte Chemie, Volume 138, Issue 10, 2 March 2026.
Triply gated isomerization: In polar solvents, a phosphorus‐containing indirubin photoswitch undergoes visible‐light‐driven Z→E isomerization only when protonated, and reverts thermally via nucleophile‐catalyzed back‐isomerization. This three‐way control by light, acid, and nucleophile enables reversible photoisomerization.

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 ...
