Morphological and Ontogenetic Skin Color Changes in the American Alligator (Alligator mississippiensis)

open access: yesAnimals, 2023
To assess skin color change in alligators, we maintained animals in differently lighted environments and also measured skin colors in an ontogenetic series of wild animals. Juvenile alligators maintained in black enclosures exhibited a gradual lightening

Color-Shift Measurement in Microlensing-Induced Stellar Variation from Future Space-Based Surveys

open access: yes, 2008
If a microlensing event is caused by a star, the event can exhibit change in color due to the light from the lens. In the previous and current lensing surveys, the color shift could not be used to constrain the lens population because the blended light ...

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

Environmental determinants and controls of skin color change in neotropical anurans [PDF]

open access: yes, 2013
Physiological color change is a strategy present in many groups of vertebrates and invertebrates. Animals showing this behavior have become model taxa in the study of camouflage because they are able to respond dynamically to changes in the environment ...

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions

open access: yesFEBS Letters, EarlyView.
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

Safety and Effectiveness of a Novel Color Corrector Serum for Causing Temporary Changes to Tooth Shade: A Randomized Controlled Clinical Study

open access: yesDentistry Journal
Tooth color is a major driver of facial esthetics. While permanent changes in tooth shade can be achieved by bleaching and restorations, there is a need for cosmetic products that can cause reversible color changes.

An Approach to Color Change and Quality Relation in Roughages

open access: yesJournal of Agricultural Sciences, 2019
In this work, it was aimed to associate CIELAB Scale (L*, a*, b*) with some quality parameters of roughages such as pH, crude protein (CP) and relative feed value (RFV).
