Food Toxicology and Safety: Evaluating Dietary Risks and Functional Ingredients

open access: yesFood Bioengineering, EarlyView.
The pyramid's foundation reminds us that true health begins with daily habits—engage in 30–60 min of physical activity, nurture social connections and secure 7–9 h of restorative sleep each night to support metabolism, mood regulation, and hormonal balance—while continuously hydrating with 8–12 glasses of water and unsweetened herbal infusions (green ...

Glial Versus Neuronal Na+/K+‐ATPase in Activity‐Evoked K+ Clearance and Their Sensitivity to Elevated Extracellular K+

open access: yesGlia, EarlyView.
The glial Na+ pump regulates [K+]o during neuronal activity, and the neuronal version restores [K+]o to baseline. Spreading depression‐related rise of K+ does not cause SD propagation via suppression of Na+/K+‐ATPase or glutamate transport. ABSTRACT Neuronal activity in the central nervous system is associated with a [K+]o transient that is swiftly ...

Pyrazine‐Embedded 2D Conjugated Metal–Organic Framework with Quasi‐Honeycomb Lattice for High‐Capacitance Lithium‐Ion Storage

open access: yesAngewandte Chemie, Volume 137, Issue 27, July 1, 2025.
A Cu‐OHDDQP 2D conjugated metal–organic framework (2D c‐MOF) was synthesized possessing a unique quasi‐honeycomb topology, from a pyrazine‐fused, D2‐symmetric ligand. The achieved 2D c‐MOF electrode displayed a remarkable gravimetric capacitance up to 452 A g−1 for electrochemical lithium storage.
