Preparation of Antioxidant Peptides Derived From Quinoa Protein and Evaluation of Their Antioxidant Activity Through a D-Galactose-Induced Aging Mice Model. [PDF]

Food Sci Nutr
Quinoa protein peptides (QPP) were prepared via pepsin hydrolysis and showed strong in vitro antioxidant activity. In D‐galactose‐induced aging mice, QPP alleviated organ damage, enhanced antioxidant enzyme activities, and upregulated hepatic antioxidant gene and protein expression. QPP is a promising natural anti‐aging ingredient for functional foods.

Amyloid β alters vascular CaV1.2 channel spatiotemporal properties

The Journal of Physiology, EarlyView.
Abstract figure legend Amyloid‐β1‐42 (Aβ1‐42) triggers a male‐specific signalling cascade influencing CaV1.2 spatiotemporal properties in cerebral vascular smooth muscle. The signalling pathway involves NADPH oxidase (NOX)‐derived reactive oxygen species (ROS) activation of protein kinase C (PKC). Aβ1‐42 can also activate protein kinase A (PKA).

Stac2 genetic deletion alters mouse chromaffin cells’ CaV channel composition, increases membrane excitability and reduces vesicle exocytosis

The Journal of Physiology, EarlyView.
Abstract figure legend Stac2 adaptor protein is expressed in neurons and endocrine cells. Using a global Stac2 knockout mouse model here we investigated the role of endogenous Stac2 in adrenal gland mouse chromaffin cell (MCC) excitability and catecholamine vesicle exocytosis.

Intrinsic pH chemosensitivity of acutely dissociated medullary serotonergic and retrotrapezoid neurones

The Journal of Physiology, EarlyView.
Abstract figure legend Central respiratory chemoreceptors (CRCs) are critical for maintaining normal systemic levels of pH and PCO2. A CRC must respond to pH via intrinsic mechanisms. Here we quantified intrinsic chemosensitivity of medullary 5‐HT neurones and retrotrapezoid nucleus (RTN) neurones using acute dissociation.

Effects of Low Temperature–Ultrasound–Papain (LTUP) Combined Treatments on Purine Removal from Pork Loin and Its Influence on Meat Quality and Nutritional Value

Foods
A combined pretreatment method of “low temperature-ultrasound-papain” (LTUP) was proposed to remove the purine of pork loins. Compared with untreated pork loin, under optimal conditions (temperature 58 °C, ultrasound density 100 W/cm2, and papain ...

Early Developmental Neuronal Activity Impacts Oligodendrocyte Differentiation Through AMPA Receptors

Glia, Volume 74, Issue 8, August 2026.
In early brain development, neuronal activity reduces OPC differentiation. Decreased neuronal activity changes oligodendrocyte gene expression, including upregulating glutamate receptor genes. AMPA signaling regulates the final stages of OPC differentiation.

Sphingosine‐1‐Phosphate Receptor 1 Regulates Competition Dependent Astrocyte Morphogenesis and Tiling in Murine Cortex

Glia, Volume 74, Issue 8, August 2026.
Neuronal contact‐induced expression of S1PR1 in astrocytes is regulated by JAK‐STAT3 signaling. Astrocytic S1PR1 modulates cortical astrocyte morphogenesis. Astrocytic S1PR1 regulates astrocyte territorial overlap/tiling in a competition dependent manner.

Exploration of a mutant enzyme protein with active site fluctuations at 330 K via machine learning and molecular dynamics simulations

AIP Advances
Control of active site fluctuations in enzyme proteins would significantly expand their application fields. Because papain typically has higher activity at 330 K, shifting the temperature to 330 K may help to expand its range of use in medical treatment,

Elimination of tau tangles and soluble aggregates with the small molecule ACI‐16664 prevents neurodegeneration in vivo

Alzheimer's &Dementia, Volume 22, Issue 7, July 2026.
Abstract INTRODUCTION Pathological tau aggregates are key therapeutic targets in Alzheimer's disease (AD), but current approaches face limitations including poor intracellular penetration, lack of selectivity for aggregated over physiological tau, or reliance on invasive administration.

Polygonatum cyrtonema Polysaccharides‐Derived Metabolic Meta Alleviates ALD via a Gut–Liver Axis–Mediated, Bifidobacterium pseudolongum–Driven Suppression of the AA Metabolism–MAPK Signaling Network

Food Frontiers, Volume 7, Issue 4, July 2026.
This study demonstrates that the hepatoprotective effect of Polygonatum cyrtonema polysaccharide (PCP) is mediated by its gut microbiota‐derived metabolome, which enriches Bifidobacterium pseudolongum, suppresses the gut–liver axis of AA metabolism, and inhibits hepatic MAPK signaling. ABSTRACT Polygonatum cyrtonema, a traditional Chinese medicinal and
