Deciphering Branched Galactomannan Structures via Multistage Ion Mobility MS and MSn Fragmentation (Multistage IMSn)

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Hemicelluloses are abundant carbohydrate components in plant cell walls. They play a crucial structural role in binding cellulose microfibrils, in addition to other biological functions. Their high structural variability directly influences their biological properties, making it important to establish a structure–function ...

Investigating Impacts of Amino Acids on the Structural Stability of Anionic Biomembranes

open access: yesChemSystemsChem, Volume 7, Issue 2, March 2025.
Glycine and lysine interact with the anionic membrane composed of POPC and POPG (1 : 1). Lysine partitions into the membrane and induces structural alterations, while the membrane remains impermeable to it. In contrast, glycine causes no physicochemical damage and permeates through the membrane.

Simple Hydroxybenzene Molecules as Thermally Stable Catalysts

open access: yesChemSystemsChem, EarlyView.
Hydroxybenzene molecules, including tannic acid, catalyze the hydrolysis of p‐nitrophenylacetate (pNPA) to p‐nitrophenol and thioacetylcholine (tAChI) to thiocholine. The catalytic performance is governed by the number and arrangement of hydroxyl groups, as well as polymer formation during incubation.

Impact of Acute and Sub‐Acute Gluten Exposure on Gastrointestinal Symptoms and Psychological Responses in Non‐Coeliac Gluten Sensitivity: A Randomised Crossover Study

open access: yesUnited European Gastroenterology Journal, EarlyView.
ABSTRACT Background/Aims Non‐coeliac gluten sensitivity (NCGS) is a controversial entity, characterised by symptom improvement with gluten exclusion in the absence of coeliac disease. We primarily investigated the effects of acute and sub‐acute gluten on psychological and mood profiles, with secondary outcomes examining gastrointestinal symptoms and ...

Gut Microbiota as a Mediator Between Intestinal Fibrosis and Creeping Fat in Crohn's Disease

open access: yesUnited European Gastroenterology Journal, EarlyView.
ABSTRACT Intestinal stricture remains one of the most challenging complications in Crohn's disease, and its underlying mechanisms are poorly understood. Accumulating evidence suggests that gut microbiota is significantly altered in stenotic intestines and may play a key role in the development of fibrogenesis in Crohn's disease.
