Photochemistry and Photobiology, Volume 102, Issue 2, Page 480-488, March/April 2026.In this study, we developed giant plasma membrane vesicles (GPMVs) from Leishmania amazonensis promastigote membranes to investigate the role of protein‐embedded membranes in methylene blue (MB) photooxidation. Upon MB photoactivation in model lipid membranes (giant unilamellar vesicles, GUVs), a distinct photooxidation effect was observed, marked by ...

International Journal of Gynecology &Obstetrics, Volume 172, Issue 2, Page 850-865, February 2026.Abstract Maternal mortality remains a critical global public health issue, particularly in low‐ and middle‐income settings where failures in surveillance, early diagnosis, and clinical decision making compromise obstetric care. In this context, the present study aimed to critically review the scientific literature on the use of artificial intelligence (

Random encounter modelling as a viable method to estimate absolute abundance of reef fish
Methods in Ecology and Evolution, Volume 17, Issue 2, Page 598-614, February 2026.Abstract Remote underwater video (RUV) surveys are increasingly replacing diver‐based underwater visual censuses (UVCs) in fish ecology studies, especially on coral reefs. However, extracting reliable estimates of abundance or density from video footage is a major challenge, with most studies using a metric of relative abundance, MaxN (maximum number ...

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.Our study shows that the generalized structure of urban plant–pollinator interactions is mirrored in the mechanisms that shape them, as interactions are governed primarily by less restrictive drivers such as abundance and spatiotemporal overlap rather than by trait matching.

Prognostic Value of Scoring and 0-Upcrossing in Statistical Quality Control
AppliedMathRising temperatures in industrial processes are a serious alert that the system can be shifting from an In Control (InC) to an Out of Control (OutC) state, causing waste, financial losses and, eventually, disaster.
