Real‐world prevalence of PD‐L1 positivity in early‐stage/metastatic triple‐negative breast cancer: primary results and pathology insights from the global retrospective observational VANESSA study

open access: yesHistopathology, Volume 88, Issue 7, Page 1373-1384, June 2026.
In the real‐world VANESSA study in triple‐negative breast cancer, PD‐L1‐positive prevalence was 38% in early‐stage and 20% in metastatic tumours, lower than in prospective trials. The lower prevalence in smaller versus larger tissue samples and by local versus central assessment underlines the importance of robust PD‐L1 testing to determine eligibility

Landscape features predict broad‐scale seed rain patterns across fragments of the Brazilian Atlantic Forest

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
Along with precipitation, forest cover emerges as a fundamental driver of alpha and beta diversity in the seed rain. This highlights the role of habitat amount at the landscape level over patch‐level features, like patch size, for seed dispersal. However, increased seed density can be related to higher dispersal rates in forest borders.

The Binding of 3‐O‐Methylfluorescein Phosphate to the Catalytic Domain of the Human CDC25B Phosphatase: A Structural Investigation

open access: yesChemBioChem, Volume 27, Issue 7, 14 April 2026.
Structural studies on the complex that CDC25B C473S (CDC25B‐S) forms with the 3‐O‐methylfluorescein phosphate (3‐OMFP) reveal how the fluorogenic substrate binds CDC25B‐S, engaging key binding regions and inducing structural adjustments that stabilize the protein.

From Barns to Bushes: Exploring the ECOFF‐Based Non‐Wild‐Type Status of Campylobacter spp. in Pets, Livestock, Synanthropic Birds and Wild Animals in Northwestern Italy

open access: yesZoonoses and Public Health, Volume 73, Issue 1, Page 30-44, February 2026.
ABSTRACT Introduction Antimicrobial resistance (AMR) poses a significant threat to both humans and animals. Zoonotic bacteria, such as Campylobacter, contribute to human infections and the spread of AMR, particularly through livestock, pets and wildlife. We investigated the prevalence, distribution and EUCAST ECOFF‐based wild‐type (WT) vs.

Analysis of a Cretaceous (late Aptian) high-stress ecosystem: The Romualdo Formation of the Araripe Basin, northeastern Brazil

open access: yesCretaceous Research, 2019
Abstract The Cretaceous (upper Aptian) Romualdo Formation of the Araripe Basin, northeastern Brazil, is a marine-influenced, predominantly fine-grained siliciclastic unit. In the eastern part of the basin, it corresponds to a depositional sequence composed of two transgressive-regressive cycles.

Morphology and paleoecology of a hybodontiform with serrated teeth, Priohybodus arambourgi, from the Late Jurassic of northeastern Brazil

open access: yesThe Anatomical Record, Volume 309, Issue 1, Page 5-32, January 2026.
Abstract Hybodontiformes was a diverse, successful, and important group of shark‐like chondrichthyans known from a variety of ecosystems. Some representatives of the order had a wide palaeogeographic distribution, as is the case with Priohybodus arambourgi. With a multicuspidate crown, P. arambourgi was the first hybodontiform to develop fully serrated
