Identification and characterization of mycosporine-like amino acid in the cyanobacterium Scytonema sp. HKAR-16 by HPLC, Raman spectroscopy, and ESI-MS [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2022 The incidence of ultraviolet radiation has increased on the Earth's surface due to depletion of the stratospheric ozone layer which has several detrimental effects on living organisms including cyanobacteria. Mycosporine-like amino acids (MAAs) are eco-

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.

The effect of a topically-applied cosmetic oil formulation on striae distensae
South African Family Practice, 2009 Background: Stretch marks or striae distensae are tears in the dermis, above which the epidermis remains intact. Striae result from rapid expansion of the underlying tissue, e.g. during puberty, pregnancy or rapid weight gain. The prevalence of striae is

Effects of Low-Level Artificial Light at Night on Kentucky Bluegrass and an Introduced Herbivore
Frontiers in Ecology and Evolution, 2021 Increasing evidence suggests that artificial light at night (ALAN) can negatively impact organisms. However, most studies examine the impacts of ALAN on a single species or under high levels of artificial light that are infrequent or unrealistic in urban

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.
