β‐Hydroxybutyrate reduces neuronal excitability via GIRK channels

Epilepsia, EarlyView.
β‐Hydroxybutyrate decreases neuronal excitability by activating GIRK channels through HCAR2 signaling, providing a cellular mechanism that may contribute to the antiseizure effects of the ketogenic diet. Abstract Objective The ketogenic diet is used to treat drug‐resistant epilepsy, yet the molecular mechanisms coupling metabolic state to seizure ...

Absence seizures: Update on signaling mechanisms and networks

Epilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Status epilepticus: Updates on mechanisms and treatments

Epilepsia Open, EarlyView.
Abstract Status epilepticus (SE) consists of prolonged, self‐sustaining seizures and is a common neurological emergency that causes respiratory compromise and neuronal injury. Without prompt treatment, the seizures can become resistant to benzodiazepines, leading to the progressive evolution of established, refractory, and super‐refractory SE.

Glycolytic alterations as biomarkers in polycystic kidney disease: A study using a PKD1 knockout model in NRK‐52E rat kidney epithelial cells

Physiological Reports
Polycystic kidney disease (PKD) is a genetic disorder characterized by the formation of fluid‐filled cysts in the kidneys, often resulting in progressive renal impairment.

Neonatal seizures and GABAergic drugs: Scylla and Charybdis?

Epilepsia Open, EarlyView.
Abstract Neonates have a high incidence of seizures that are frequently difficult to control with conventional first‐line anti‐seizure medications, which are gamma‐aminobutyric acid (GABA) agonists. The reasons for this clinical problem are multifold but are likely related to the unique physiology of the immature nervous system. Specifically, the early

Computational protein stability analysis of SCN1A missense variants reveals domain‐dependent stability patterns

Epilepsia Open, EarlyView.
Abstract Objective To determine whether computational protein‐stability predictions discriminate pathogenic from benign SCN1A missense variants, and to characterize the structural distribution of predicted destabilization among pathogenic variants. Methods On an AlphaFold3‐predicted Nav1.1 structure, FoldX, and Rosetta Cartesian ΔΔG were computed for a

Response to anti‐seizure medications in children carrying novel or previously reported HCN1 gene variants

Epilepsia Open, EarlyView.
Abstract Objective Variants in the HCN1 gene cause a syndrome of childhood epilepsy and developmental disability with a broad phenotypic range. Many affected children manifest with early infantile epileptic encephalopathy (EIEE) and highly drug‐resistant epilepsy.

Research progress on the depth of anesthesia monitoring based on the electroencephalogram

Ibrain, Volume 11, Issue 1, Page 32-43, Spring 2025.
Electroencephalogram (EEG) can noninvasive, continuous, and real‐time monitor the state of brain electrical activity, and the monitoring of EEG can reflect changes in the depth of anesthesia (DOA). The development of artificial intelligence can enable anesthesiologists to extract, analyze, and quantify DOA from complex EEG data.

Nuclear‐Spin Hyperpolarization of Biomolecules by Optically Enhanced NMR at Ultra‐High Field

Journal of the Chinese Chemical Society, EarlyView.
This study shows that the sensitivity of liquid‐state NMR spectroscopy can be dramatically increased, with enhancement factors up to 160‐fold on a 1.1 GHz ultra‐high‐field NMR spectrometer. This advance exploits low‐concentration photochemically induced dynamic nuclear polarization (LC‐photo‐CIDNP) and it enables facile atomic‐resolution detection of ...
