Synthetic Cells on Demand: From Molecular Stimuli to Cellular Functions

ChemSystemsChem, Volume 8, Issue 2, March 2026.
ABSTRACT Synthetic cells constructed via bottom‐up approaches using lipid or polymer vesicles have become essential tools for mimicking cellular functions and studying synthetic biological systems. These vesicles can undergo morphological changes and trigger internal reactions in response to external stimuli, such as osmotic pressure, temperature, pH ...

Effect of cadmium chloride on general body colouration and chromatophores of stinging cat fish, Heteropneustes fossilis (Bloch) [PDF]

, 2018
Chromatophores, specialized pigment cells in poikilothermic animals, have shown great potential in their use as a cell-based biosensor in the detection of a broad range of environmental toxicants, as structure and number of chromatophores alters ...

Enrichment of Neural Crest Cells by Antibody Labeling and Flow Cytometry for Single‐Cell Transcriptomics in a Lizard

Evolution &Development, Volume 28, Issue 1, March 2026.
Using wall lizard embryos, we present an approach to isolate neural crest cells by antibody labeling and flow cytometry followed by single‐cell RNA sequencing. The approach does not require transgenic animals, and thus enables addressing evo‐devo questions across a range of vertebrate taxa.

An Annotated Checklist of the Freshwater Fishes of Texas, with Keys to Identification of Species [PDF]

, 1991
Forty-five families and 247 species of fishes are known to inhabit the freshwaters of Texas. We report on the distribution and status of these fishes and provide a key to their identification.

Epigenetics in Captivity: Restoring Wild Phenotypes in Captive‐Reared Salmonids

Evolutionary Applications, Volume 19, Issue 3, March 2026.
ABSTRACT Captive rearing is a common practice for the stocking, conservation, and supplementation of fish species worldwide, but captive‐reared fish can exhibit altered phenotypes leading to reduced fitness in nature compared to wild conspecifics. In salmonids, certain studies have found limited genetic differentiation between wild and captive‐reared ...

Aspidoras mephisto, new species: The first troglobitic Callichthyidae (Teleostei: Siluriformes) from South America.

PLoS ONE, 2017
Aspidoras mephisto n. sp. is described from the Anésio-Russão cave system, upper Tocantins River basin, Goiás, Brazil. The species can be readily distinguished from its congeners by troglomorphic features and also by presenting the following combination ...

Melanocortin systems on pigment dispersion in fish chromatophores

Frontiers in Endocrinology, 2012
Alpha-Melanocyte-stimulating hormone (alpha-MSH) is responsible for pigment dispersion in the chromatophores of fish and other tetrapods such as amphibians and reptiles.

Freshwater and Sediment Host Distinct Yet Overlapping Microeukaryotic Communities, With Sediment Communities Less Impacted by Treated Wastewater

Journal of Eukaryotic Microbiology, Volume 73, Issue 2, March/April 2026.
ABSTRACT Freshwater and sediment environments host diverse microeukaryotic communities that differ in structure and composition, yet exhibit taxonomic overlap. Using 18S V9 rRNA gene sequencing, we compared communities from these habitats in controlled 10‐day mesocosm experiments, examining diversity, overlap, and responses to treated wastewater (TWW).

Database of low‐temperature absorption and fluorescence spectra of native photosynthetic tetrapyrrole macrocycles

Photochemistry and Photobiology, Volume 102, Issue 2, Page 457-469, March/April 2026.
The absorption and fluorescence spectra at 77 K (frozen glass) and room temperature (fluid solution) are provided for 12 native photosynthetic macrocycles encompassing one porphyrin, eight chlorins, and 3 bacteriochlorins. Abstract Low‐temperature (77 K) absorption and fluorescence spectra of 12 naturally occurring photosynthetic tetrapyrrole ...

The influence of chromatic background on the photosensitivity of tilapia erythrophores

Biology Open, 2014
Summary Non-mammalian vertebrates and invertebrates use extraretinal photoreceptors to detect light and perform diverse non-image-forming functions. Compared to well-studied visual systems, the effect of ambient light conditions on photosensory systems ...
