Parametric Analysis of Spiking Neurons in 16 nm Fin Field‐Effect Transistor Technology

Advanced Intelligent Discovery, EarlyView.
Energy efficient computing has driven a shift toward brain‐inspired neuromorphic hardware. This study explores the design of three distinct silicon neuron topologies implemented in 16 nm fin field‐Effect transistor technology. While the Axon‐Hillock design achieves gigahertz throughput, its functional fragility persists. The Morris–Lecar model captures

Astrocytic Mitochondria Transplantation Rescues Neuron Loss and Dendritic Injuries in Acute Cerebral Ischemic Stroke Mouse Model by Flexibly Regulating Mitochondria Dynamics

Annals of Neurology, EarlyView.
Objective Cerebral ischemic stroke causes neuronal oxygen/energy deprivation, disrupting mitochondrial function including reduced membrane potential and bioenergetics, exacerbating neuronal injury. Mitochondrial defects are, therefore, a central neuropathological node and potential therapeutic target.

Membrane potential hyperpolarization: a critical factor in acrosomal exocytosis and fertilization in sperm within the female reproductive tract

Frontiers in Cell and Developmental Biology
Hyperpolarization of the membrane potential (Em), a phenomenon regulated by SLO3 channels, stands as a central feature in sperm capacitation—a crucial process conferring upon sperm the ability to fertilize the oocyte.

Improving the Hyperpolarization of 31P Nuclei by Synthetic Design

Journal of Physical Chemistry B, 2015
Traditional 31P NMR or MRI measurements suffer from low sensitivity relative to 1H detection and consequently require longer scan times. We show here that hyperpolarization of 31P nuclei through reversible interactions with parahydrogen can deliver ...

The evolving therapeutic landscape of spinal muscular atrophy – A scoping review of investigational agents, emerging delivery technologies and strategic innovations

British Journal of Clinical Pharmacology, EarlyView.
Spinal muscular atrophy (SMA) is a severe neuromuscular disease with emerging therapeutic complexity. This review aims to systematically map the global pipeline of investigational treatments for SMA. Using ClinicalTrials.gov and complementary international registries, we identified 21 planned or ongoing interventional trials from 2020 to 2025 targeting

Advances in Parahydrogen‐Induced Polarization for Nuclear Magnetic Resonance of Peptides, Proteins, and Biopolymers

ChemistryEurope, EarlyView.
Hyperpolarization by parahydrogen‐induced polarization enhances the sensitivity of nuclear magnetic resonance spectroscopy of amino acids, peptides, mini‐proteins, and biopolymers using nonnatural amino acids with unsaturated side chains up to three orders of magnitude.

Mechanisms of SCN2A loss of function do not predict presence or phenotype of epilepsy

Epilepsia, EarlyView.
Abstract Objective SCN2A loss‐of‐function (LoF) variants are associated with epilepsy (onset age ≥ 3 months), intellectual disability (ID), and autism spectrum disorder (ASD). Despite numerous identified variants and the description of phenotypic subgroups, relationships between Nav1.2 channel dysfunction and clinical phenotypes remain unclear.
