Ultrasound‐assisted recirculation extraction as an innovative approach for obtaining bioactive compounds from grape pomace

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Grape pomace, a by‐product generated during winemaking, still retains bioactive compounds with potential applications in the food, pharmaceutical and nutraceutical sectors. This work investigated ultrasound‐assisted extraction (UAE) coupled with a recirculation system as a strategy to improve their recovery.

Intercomparison of carbon‐13 and carbon‐14 tracer approaches for estimating marine calcification and net primary production

Limnology and Oceanography: Methods, EarlyView.
Abstract Accurate measurements of phytoplankton net primary production (NPP) and calcification are essential for quantifying marine carbon cycling, yet in situ calcification rates remain poorly constrained. We compared 13C‐ and 14C‐based tracer methods for NPP in laboratory cultures of the diatom Chaetoceros tenuissimus and the coccolithophore ...

Zero‐Dimensional Perovskite‐Inspired Scintillator‐Based High‐Radiation‐Resistant Radionuclide Analyzer Free From Irreversible Degradation

Laser &Photonics Reviews, EarlyView.
A zero‐dimensional perovskite‐inspired scintillator (Cs3Cu2I5) is developed as a high‐radiation‐resilient radionuclide analyzer capable of operating under extreme γ‐ray environments. Even after 200 kGy irradiation, the device fully restores its original spectroscopic performance through simple thermal annealing, demonstrating intrinsic defect ...

The Tasty Side of Numbers: How Vowel Type Influences Taste Perceptions for Numerical Brand Names

Psychology &Marketing, EarlyView.
ABSTRACT Numerical brand names are commonly used in food marketing yet underexplored for their sensory impact. Relying on processing fluency theory, across four studies, including an IAT (n = 149), a quantitative and qualitative lexical analysis of professional wine tasting notes (n = 695), an online study (n = 306), and archival consumer wine ratings (

Thiolate Salt Mediated Dynamic Silyl Ether Exchanges for Polymer Network Design and Deconstruction

Macromolecular Rapid Communications, EarlyView.
This work introduces thiolate salts as mediators for dynamic silyl ether exchange. This platform enables the synthesis of reprocessable covalent adaptable polymer networks (CANs) and allows for sterically controlled, and tunable deconstruction of silyl ether‐containing thermosets.

Predicting Mesoscopic Larmor Frequency Shifts in Ex Vivo Porcine Optic Nerve

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Larmor frequency shifts in white matter (WM) vary with fiber orientation due to anisotropic microstructure. Since clinical voxels are significantly larger than these microscopic frequency variations, the measured signal represents a bulk average of local shifts.

Protecting CEACAM1 Expression Prevents Diet‐Induced Metabolic Dysfunction and Hepatic Fibrosis in Male Mice

Obesity, EarlyView.
ABSTRACT Objective High‐fat diet represses Ceacam1 transcription via a PPARα‐mediated mechanism to cause insulin resistance before inflammation develops. The current study investigated whether mutating PPRE‐RXRα in Ceacam1 promoter prevents diet‐induced metabolic abnormalities and hepatic fibrosis in male C57BL6/J mice.
