Dual‐Responsive Chitosan‐Grafted PNIPAAm Hydrogel Eye Drop Incorporating Insulin‐Imprinted Microgels for Dry Eye Syndrome Treatment

Macromolecular Bioscience, Volume 26, Issue 6, June 2026.
ABSTRACT Dry eye syndrome (DES) happens as a result of inadequate tear secretion or excessive evaporation, which leads to ocular surface irritation and damage. A major therapeutic challenge is maintaining effective drug concentrations, as topical formulations are rapidly cleared by blinking and tear turnover.

SIRT1 Prevents Ferroptosis in Corneal Epithelial Cells by Enhancing HIF1α Protein Stability in Dry Eye Disease

Advanced Science, Volume 13, Issue 26, 8 May 2026.
Hyperosmotic stress drives ferroptosis in corneal epithelium via SIRT1 downregulation. This work demonstrates that SIRT1 activation stabilizes HIF1α, which transcriptionally upregulates GPX4 to inhibit lipid peroxidation and cell death. The identified SIRT1/HIF1α/GPX4 axis reveals a novel defense mechanism and potential therapy for dry eye disease ...

Future Climate Change Assessment in Flood Risk Management: A Synthesis of Practices in Germany and the BeNeLux Countries

Journal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT Climate change, with its links to an intensified water cycle, heavier rainfall, and potentially higher flood peaks, raises concerns about the adequacy of current flood risk management. The devastating July 2021 floods in western Europe underscored these concerns, highlighting the need for transboundary cooperation and shared expertise in ...

Uso compartido de una letrina por el zorro Cerdocyon thous y perros domésticos Canis familiaris (Carnivora: Canidae) en una zona periurbana del Valle de Aburrá (Antioquia, Colombia)

Mammalogy Notes, 2014
Muchas especies de carnívoros conforman letrinas al acumular sus heces en sitios específicos. Estas sirven para marcar su territorio y advertir a otros individuos sobre su presencia, como una estrategia para evitar competencia directa por el área y sus ...

Urbanization of seed dispersal networks

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract Rapid urban expansion is affecting the composition of wild communities and creating novel ecosystems worldwide. Seed dispersal is key for ecosystem persistence, particularly in fragmented landscapes. However, generalizations regarding the impacts of urbanization are still difficult due to the lack of studies encompassing the urban matrix.

Bridge Clogging in Belgium and Germany During the 2021 Floods

Water Resources Research, Volume 61, Issue 11, November 2025.
Abstract During summer of 2021, devastating river floods occurred in Western Europe as a result of extreme rainfall. At numerous bridges, debris accumulations were observed, exacerbating flooding upstream by impeding waterflow and sometimes contributing to bridge failure.

Actual Versus Potential Impact: Leveraging Life Cycle Assessment to Implement Business Models for Sustainability

Business Strategy and the Environment, Volume 34, Issue 6, Page 6563-6593, September 2025.
ABSTRACT Research on business models for sustainability (BMfS) has primarily focused on the conceptual aspects and sustainability potential of BMfS rather than their actual impact. There is a need to understand whether BMfS have less environmental impact on society than conventional business models and in what context and conditions they can reduce ...
