The ‘Polluter Pays Principle’: environmental liabilities and scientific evidence under the Italian law system

Acque Sotterranee, 2019
The “Polluter Pays” Principle is a cornerstone in environmental law. The Italian law system, like other European ones, show that this principle, although being easy to understand, is hard to be implemented.

Direct Recycling of Mixed‐Oxide Cathodes: Balancing Cost, Performance and Environmental Trade‐Offs

Advanced Science, EarlyView.
Direct regeneration routes for mixed‐oxide lithium‐ion battery cathodes are systematically compared using harmonized techno‐economic, electrochemical, and environmental metrics. Solid‐state, hydrothermal, molten salt, electrochemical, and chemical relithiation methods are benchmarked to identify performance, cost, and sustainability trade‐offs.

Production of fiberboards from shives collected after continuous fiber mechanical extraction from oleaginous flax

Journal of Natural Fibers, 2019
In this study, fiberboards were produced from shives collected after continuous fiber mechanical extraction from oleaginous flax straw. Fiberboards were produced through thermo-pressing, and their mechanical and thermomechanical properties were studied ...

Tetraploid Wheats: Valuable Source of Phytosterols and Phytostanols

Agronomy, 2019
Phytosterols are known as healthy compounds obtained mainly from oilseed crops. Cereals were also studied for their sterols content. Few insights have been devoted to other tetraploid species than emmer and durum wheats.

PAF Triggered Pyroptotic NETosis Aggravates Myocardial Ischemia/Reperfusion Injury

Advanced Science, EarlyView.
Platelet activating factor (PAF) secreted by cardiomyocytes during MI/R, drives NETs formation and subsequent NETosis. PAF/NETosis signaling activation is an initiative and causal factor in driving MI/R injury. This study identifies dapagliflozin as a potent NETosis inhibitor, and demonstrates that manipulating PAF‐NETosis signal by dapagliflozin or ...

Dynamic Shifts in ER–Plasma Membrane Junctions Signaling Define Pro‐Metastatic N‐Glycosylation and Predict Prostate Cancer Progression

Advanced Science, EarlyView.
Prostate cancer remains a leading cause of male cancer death, yet screening cannot reliably identify aggressive disease, underscoring the need for tissue biomarkers. It is shown that primary tumors increase ER–plasma membrane junction signaling via STIM1/ORP5, whereas metastasis features their loss, Golgi dispersal, and rapid conversion of high‐mannose
