Ultrastructure of the dermal chromatophores in the Fringe-toed lizard, Acanthodactylus orientalis

open access: yesZoologia (Curitiba), 2017
Histology and electron microscopic studies of the dorsal skin of the Fringe-toed lizard, Acanthodactylus orientalis Angel, 1936, showed three types of dermal chromatophores: xanthophores, iridophores and melanophores. These pigment cells were observed in

Chloroplast and mitochondrial genomes of Sphaerosorus coelastroides Pascher (Xanthophyceae) from Central Appalachia, Clinch River, Virginia, United States

open access: yesJournal of Phycology, Volume 62, Issue 4, Page 1185-1192, August 2026.
Abstract This report describes the isolation and culture of Sphaerosorus coelastroides from the plankton of a freshwater river in the central Appalachian mountain chain. This alga was first observed in a dry freshwater riverbed in Central Europe in 1908 and, since then, has been included in Xanthophyceae surveys from nearly all continents with ...

Trehalose as a tool for studying the molecular mechanisms of electron transfer in photosynthetic systems

open access: yesFrontiers in Photobiology
In this review, we consider the effects of trehalose on charge transfer processes in three distinct photosynthetic systems under different conditions, namely: (i) the effect of relative hydration of the trehalose glassy matrix on forward and backward ...

Optical extinction of size-controlled aerosols generated from squid chromatophore pigments

open access: yesAPL Materials, 2017
Nanophotonic granules populate the interior of cephalopod chromatophores, contributing to their visible color by selectively absorbing and scattering light.

Description of the Early Development of Hoplias intermedius (Günther, 1864) (Characiformes: Erythrinidae)

open access: yesJournal of Morphology, Volume 287, Issue 7, July 2026.
This study provides the first description of the early development of Hoplias intermedius (Characiformes: Erythrinidae), from the embryonic to the juvenile stage. The morphological, meristic, and morphometric characterization contributes to understanding the ontogeny and developmental transitions of Neotropical fishes, supporting taxonomy, conservation,

The structure of chromatophores from purple photosynthetic bacteria fused with lipid-impregnated collodion films determined by near-field scanning optical microscopy [PDF]

open access: yes, 1999
Lipid-impregnated collodion (nitrocellulose) films have been frequently used as a fusion substrate in the measurement and analysis of electrogenic activity in biological membranes and proteoliposomes. While the method of fusion of biological membranes or

An Overview of Pterin Analysis in Biological Samples: From Occurrence and Properties to Sample Pretreatment Combined With Hyphenated Separation Techniques

open access: yesJournal of Separation Science, Volume 49, Issue 7, July 2026.
ABSTRACT Pterins are a structurally diverse group of biologically active compounds within the pteridine family, with key roles in pigmentation, redox metabolism, light sensing, and cellular signaling across a wide range of organisms. Their quantification in biological samples is analytically demanding due to their high polarity, chemical instability ...
