Effects of Acridines on Morphogenesis

open access: yesNature, 1968
EARLY studies of the effects of acridines on amphibian egg development tended to show that RNA synthesis is required for neural induction1. Little could be concluded from these experiments, however, because the acridines available at that time were a complex mixture of substances of unknown mode of action. Acridines have since been found to bind to and

Photoprotective potential of gadusol against ultraviolet B radiation in melanocytes

open access: yesPhotochemistry and Photobiology, EarlyView.
Gadusol protects melanocytes from ultraviolet B (UVB)‐induced damage without cytotoxicity. Abstract The increasing incidence of skin cancer, including melanoma, combined with the need for ultraviolet (UV) filters that are safe for human health and marine ecosystems, is driving the search for new photoprotective agents.

Optical spectrum of proflavine and its ions

open access: yes, 2010
Motivated by possible astrophysical and biological applications we calculate visible and near UV spectral lines of proflavine (C13H11N3, 3,6-diaminoacridine) in vacuum, as well as its anion, cation, and dication.

Zebrafish as a practical and convenient model for the study of photodynamic and photothermal therapy of solid tumors: A scoping review

open access: yesPhotochemistry and Photobiology, EarlyView.
Zebrafish provide a high‐throughput, optically transparent platform for cancer and drug screening. Their ~80% genetic homology, xenograft compatibility, and transgenic strains enable targeted photosensitizer screening, real‐time ROS and tumor imaging, and mechanistic assays, while fish embryo acute toxicity (FET) and in vitro tests streamline toxicity ...

The role of acquired host immunity in periodontal diseases

open access: yesPeriodontology 2000, EarlyView.
Abstract The aim of this narrative review is to relate the contribution of European researchers to the complex topic of the host immune system in periodontal disease, focusing on acquired immunity. Other chapters in this volume will address the genetics and autoantibody responses and other forms of immunity to periodontal disease.

Viable but Nonculturable State, a Survival Strategy for Salmonella in Aquatic Environments

open access: yesWater and Environment Journal, EarlyView.
Transition of Salmonella from a culturable state to a viable but nonculturable state under various environmental stresses and current methods for detecting viable Salmonella in environmental samples. ABSTRACT In the relentless battle for survival, Salmonella has evolved mechanisms to withstand harsh conditions such as extreme temperatures, fluctuating ...

Acridine–Isoxazole and Acridine–Azirine Hybrids: Synthesis, Photochemical Transformations in the UV/Visible Radiation Boundary Region, and Anticancer Activity

open access: yesMolecules
Easy-to-handle N-hydroxyacridinecarbimidoyl chloride hydrochlorides were synthesized as convenient nitrile oxide precursors in the preparation of 3-(acridin-9/2-yl)isoxazole derivatives via 1,3-dipolar cycloaddition with terminal alkynes, 1,1 ...

A Dynamic Change of Microglial States Occurs During the Transition From Photoreceptor Degeneration to Regeneration in Zebrafish pde6c Mutants

open access: yesGlia, Volume 74, Issue 6, June 2026.
Zebrafish pde6c mutants undergo photoreceptor degeneration from 5 dpf, but rods regenerate from 4 wpf. scRNA‐seq of retinal microglia reveals dynamic change of states between 5 dpf and 4 wpf. Two states emerge specifically during regeneration. ABSTRACT Microglia, brain‐resident immune cells, maintain brain homeostasis.

Low‐Head Dam Removal Restores Biofilm Structure but Not Function in a Temperate Stream

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Barrier removal is a common stream restoration practice aimed at restoring longitudinal connectivity, yet its effects on biofilm structure and function, through alteration of near‐bed hydrodynamics, remain unclear. Using a space‐for‐time substitution approach, we assessed how the presence and removal of a low‐head dam affect biofilm structure ...
