Effects of Exogenous Monosodium Glutamate on GABA Accumulation and Volatile/Nonvolatile Metabolites in Black Highland Barley

open access: yesFood Science &Nutrition, Volume 14, Issue 8, August 2026.
Overview of MSG‐assisted GABA enrichment and associated changes in amino acid, fatty acid, and volatile metabolite profiles in germinated black highland barley. ABSTRACT γ‐Aminobutyric acid (GABA) is a functional amino acid with multiple health benefits; however, the mechanism of its enrichment in black highland barley, particularly through precursor ...

Antiglycation of Insulin by Selected Six Bioactive Peanut Sprout Stilbenoids and Demonstration of Methylglyoxal‐Mediated Biphasic Insulin Glycation by O‐Phenylenediamine Derivatization

open access: yesFood Science &Nutrition, Volume 14, Issue 8, August 2026.
Graphical abstract demonstrates 6 peanut sprout containing stilbenoids exhibiting varied structure‐activity potency in protection of insulin integrity from glycation mediated by methylglyoxal (MG), glucose and fructose. Meanwhile, MG‐mediated biphasic insulin glycation was evidenced in Tricine SDS‐PAGE analysis and supported by O‐phenylenediamine (OPD)

Simulation‐Based Design and Evaluation of an Alkaline Direct Glycerol Fuel Cell Stack With Integrated Purification

open access: yesFuel Cells, Volume 26, Issue 4, August 2026.
ABSTRACT Direct glycerol fuel cells (DGFCs) are a promising technology, but scaling them remains a challenge due to persistent technological and economic limitations. In this context, process simulation and modeling emerge as crucial tools. This study addresses the implementation of a conventional alkaline DGFC stack model in Aspen Plus and proposes a ...

Alterations in brain metabolites in rats with experimental periodontitis: A metabolomic approach

open access: yesJournal of Periodontology, Volume 97, Issue 8, Page 1773-1783, August 2026.
Abstract Background Periodontitis (PD) is a chronic inflammatory disease with systemic effects. Emerging evidence suggests a link between periodontal inflammation and neurological changes, but the biochemical mechanisms in key brain regions, such as the hippocampus and amygdala, remain unclear.

Effect of thermosonication on the UHPLC‐QTOF‐IMS‐based metabolomic profile of orange juice

open access: yesJSFA reports, Volume 6, Issue 8, Page 309-313, August 2026.
Abstract Background This study investigated the impact of thermosonication on the metabolomic profile of orange juice to understand processing‐induced alterations in bioactive compounds and quality attributes. Results Moderate thermosonication at 45°C preserved structural siloxanes and certain amino acids, whereas higher temperatures between 60 and 75 ...

Metabolic Regulation of Macrophages in Health and Disease

open access: yesMedComm, Volume 7, Issue 8, August 2026.
Extracellular metabolites drive metabolic rewiring of glucose, lipid, and amino acid pathways in macrophages, steering their polarization toward pro‐ or anti‐inflammatory phenotypes and shaping a wide range of disease processes. Macrophages from different tissues display distinct metabolic signatures, and therapeutic strategies that target these ...

On the Origin of the Brain Semi‐Heavy Water Deuterium MR Signal Following Administration of Deuterated Metabolic Substrate: A Cautionary Tale

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 2, Page 862-870, August 2026.
ABSTRACT Purpose To evaluate the extent to which the appearance of HOD in the brain following systemic administration of a deuterated substrate is due to local brain metabolism versus body metabolism. Methods [6,6‐2H2]glucose, which is transported across the blood‐brain barrier (BBB), and [6,6‐2H2]fructose (Fruc), which does not cross the BBB, were ...
