Synthesis and Polymerization of Naphthoxazines Containing Furan Groups: An Approach to Novel Biobased and Flame‐Resistant Thermosets

open access: yesInternational Journal of Polymer Science, Volume 2018, Issue 1, 2018., 2018
Naphthoxazines are a class of compounds with potential application in obtaining high‐performance polymeric materials. Such application of these compounds, however, is still scarcely explored in the literature. Combined with the search for new high‐performance materials, the development of biobased polymers has gained a lot of attention.

A Novel Topical Emollient Plus for Canine Atopic Dermatitis: A Clinical Trial Assessing Efficacy and User Acceptance

open access: yesVeterinary Dermatology, Volume 37, Issue 2, Page 293-305, April 2026.
Background: Canine atopic dermatitis (cAD) is a common, chronic skin condition characterised by epidermal barrier dysfunction, immune dysregulation and cutaneous dysbiosis. While “emollient plus” formulations are widely used in human atopic dermatitis, their role in cAD remains underexplored. Hypothesis/Objectives: To evaluate the clinical efficacy and

Development of a SNP Panel for Geographic Assignment and Population Monitoring of Jaguars (Panthera onca)

open access: yesEcology and Evolution, Volume 15, Issue 5, May 2025.
We have developed a genome‐enabled single nucleotide polymorphism (SNP) panel for use in jaguar geographic traceability, individual identification, kinship, and sexing. Our panel, named “Jag‐SNP”, comprises 459 SNPs selected from an initial pool of 13,373,949 markers based on the inter‐biome FST, followed by rigorous filtering and addition of eight sex‐

When do citizen scientists record biodiversity? Non‐random temporal patterns of recording effort and associated factors

open access: yesPeople and Nature, Volume 7, Issue 4, Page 860-870, April 2025.
Abstract Citizen science data are increasingly used for ecological research, biodiversity conservation and monitoring. However, these data often present significant analytical challenges due to uneven recording efforts by citizen scientists. Biases caused by intra‐annual differences in levels of recording activity can be particularly severe, hindering ...
