Effect of post‐harvest ultrasound treatment on phytochemical enhancement in Gynura procumbens leaves and their protection against oxidative stress‐induced muscle atrophy

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Gynura procumbens is a medicinal plant widely recognized for its antioxidant and anti‐inflammatory properties. Despite its traditional use in Southeast Asia, its potential role in promoting muscle health has not been thoroughly investigated.

Ion Chemistry in Dielectric Barrier Discharge Ionization: Recent Advances in Direct Gas Phase Analyses

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Dielectric barrier discharge ionization (DBDI) sources, employing low‐temperature plasma, have emerged as sensitive and efficient ionization tools with various atmospheric pressure ionization processes. In this review, we summarize a historical overview of the development of DBDI, highlighting key principles of gas‐phase ion chemistry and the ...

Thermometer Ions, Internal Energies, and In‐Source Fragmentation in Ambient Ionization

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Ionization and fragmentation are at the core of mass spectrometry. But they are not necessarily separated in space, as in‐source fragmentation can also occur. Here, we survey the literature published since our 2005 review on the internal energy and fragmentation in electrospray ionization sources.

Practical Applications of Secondary/Extractive Electrospray Ionization (SESI): A Versatile Tool for Real‐Time Chemical Analysis

Mass Spectrometry Reviews, EarlyView.
ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry

Proteomics of Nitrotyrosine: Integrating Mass Spectrometry and Immunodetection in Redox‐Driven Pathology

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Nitrooxidative stress, driven by excess reactive nitrogen species like peroxynitrite, contributes to the pathogenesis of many chronic diseases. Among its molecular footprints, 3‐nitrotyrosine (3NT) has emerged as a biologically relevant marker of protein nitration.

Engineering Pd Nanostructures on Hierarchical Flower‐Like Alumina Nanosheets for the Efficient Catalytic Reduction of 4‐Nitrophenol

Nano Select, EarlyView.
Palladium nanocubes and nanoparticles supported on nanosheet‐assembled alumina (NA‐Al2O3) were investigated as highly efficient catalysts for the reduction of 4‐nitrophenol. Systematic comparisons highlight the roles of nanoparticle morphology and support structure, with PdNC@NA and PdNP@NA showing superior activity and stability over commercial Al2O3 ...
