Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Cytotoxicity of Sunset Yellow and Brilliant Blue food dyes in a plant test system

open access: yesCaryologia, 2022
Dyes used in the food industry are an important class of food additives and are often used to make processed food more visually appealing, especially to children.

Colour, health and wellbeing: the hidden qualities and properties of natural dyes [PDF]

open access: yes, 2013
This paper addresses the questions: Is it feasible that the chemicals present in the natural dyes of both plants and insects which in the past, man has exploited for their colour, could exhibit other properties?

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Effects of age and weather during moult on mountain bluebird Sialia currucoides structural colouration

open access: yesJournal of Avian Biology, 2021
Birds exhibit a vast array of colours and ornaments and while much work has focused on understanding the function and evolution of carotenoid‐based colours (red, orange, yellow), structural colouration (blue, green, purple, iridescent) can also play a ...

Medieval food and colour [PDF]

open access: yesJournal of Medieval History, 2017
For medieval people, colour provided important information about the nature of objects, and that was no less true of what they ate than of anything else.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Consumers’ preferences for visual elements on chocolate packaging

open access: yesJournal of Graphic Engineering and Design, 2019
Many recent researches focused on packaging elements as two separate groups: visual and informative elements. This study goes deeper into the group of visual elements on food packaging (i.e.

Artificial selection for food colour preferences [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2015
Colour is an important factor in food detection and acquisition by animals using visually based foraging. Colour can be used to identify the suitability of a food source or improve the efficiency of food detection, and can even be linked to mate choice. Food colour preferences are known to exist, but whether these preferences are heritable
