Assessing the Association Between Animal Color and Behavior: A Meta‐Analysis of Experimental Studies

Ecology and Evolution, Volume 14, Issue 12, December 2024.
In animals, genetic variation in color is hypothesized to have pleiotropic effects on a variety of behaviors due to shared dependence on underlying biochemical pathways. We used a phylogenetic meta‐analytic approach to examine the relationship between individual variation in aggressive behavior and variation in multiple colors.

Usefulness of serum biopterin as a predictive biomarker for childhood asthma control: A prospective cohort study

Allergology International, 2019
Background: Pteridines are metabolites of tetrahydrobiopterin, which serves as co-enzyme of nitric oxide synthase. We sought to investigate the usefulness of pteridines as biomarkers for childhood asthma control.

Serum vitamins and trace elements in vitiligo patients: A systematic review and meta‐analysis of observational studies

JEADV Clinical Practice, Volume 3, Issue 5, Page 1430-1446, December 2024.
Abstract Vitiligo is one of the most common pigmentary skin disorders, which significantly impacts the quality of life. The aetiology and pathophysiology of vitiligo are still unclear, but one of the proposed mechanisms is oxidative damage interrupting melanogenesis.

Crystal structure of a short‐chain dehydrogenase from Burkholderia cenocepacia J2315 in complex with NADP+ and benzoic acid

Acta Crystallographica Section F, Volume 80, Issue 12, Page 348-355, December 2024.
The structure of B. cenocepacia short‐chain dehydrogenase/reductase (SDR) in complex with NADP+ and benzoic acid is presented. Analysis of the structure reveals a distinctive active‐site architecture, suggesting that this protein is part of the divergent SDR subgroup.Burkholderia cenocepacia is an opportunistic human pathogen that can cause lethal ...

CRISPR/Cas9‐mediated genome editing of Frankliniella occidentalis, the western flower thrips, via embryonic microinjection

Insect Molecular Biology, Volume 33, Issue 6, Page 589-600, December 2024.
A robust methodology was developed to generate heritable mutations in a thysanopteran crop pest and virus vector (Frankliniella occidentalis, Fo) using the CRISPR/Cas9 system Two eye colour genes (Fo‐white and Fo‐cinnabar) were identified in the F. occidentalis genome to serve as targets of gene knockout with visible changes in eye pigmentation CRISPR ...
