Liquid Atmospheric Pressure MALDI (LAP‐MALDI) Mass Spectrometry: A Versatile Tool for the Characterization of Synthetic Polymers

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 16, 30 August 2026.
ABSTRACT Rationale Liquid atmospheric pressure matrix‐assisted laser desorption/ionization (LAP‐MALDI) mass spectrometry (MS) has previously been applied to the analysis of biopolymers such as peptides, proteins, and DNA, producing ESI‐like multiply charged analyte ions.

Characterization of Grape Cane Stilbenoids and Their Photo‐Degradation Products by HPLC‐DAD Coupled With Trapped Ion Mobility Spectrometry and High‐Resolution Tandem Mass Spectrometry

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 15, 15 August 2026.
ABSTRACT Rationale Bioactive (E)‐stilbenoids in vine extracts are prone to light‐induced transformation into the respective (Z)‐isomers and further degradation products, often resulting in a loss of bioactivity. We sought to study stilbenoid degradation beyond that of the well‐researched resveratrol due to the high diversity of stilbenoids in nature ...

Sensorial repercussions of the formation of vinylphenolic pyranoanthocyanins [PDF]

open access: yes, 2008
Using selected yeast, of the Saccharomyces cerevisiae specie, with hydroxycinnamate decarboxylase activity (HCDC+) we can transform anthocyanidin-3-O-glucosides from grapes into vinylphenolic pyranoanthocyanins.

Dry Deposition Strategies for MALDI–MS Imaging: Principles, Advances and Emerging Applications

open access: yesAnalytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Matrix‐assisted laser desorption/ionisation mass spectrometry imaging (MALDI–MSI) has become a pivotal tool in biomedical research, enabling untargeted, spatially resolved analysis of molecular species in complex biological tissues. Among the critical steps in MALDI–MSI workflows, matrix deposition significantly influences sensitivity, spatial

Phytotherapeutic Regulation of Matrix Metalloproteinases in Diabetic Foot Ulcer: Molecular Mechanisms and Wound Healing Perspectives

open access: yesPhytochemicals in Food and Medicine, Volume 1, Issue 2, June 2026.
Chronic inflammation in diabetic foot ulcers elevates MMP activity and suppresses TIMP and growth factor signaling, impairing tissue repair. Phytochemicals modulate NF‐κB/MAPK pathways and enhance Nrf2–TIMP expression, restoring MMP/TIMP balance, promoting collagen deposition, angiogenesis, and re‐epithelialization, leading to effective wound healing ...
