Inhibition by Pregnenolone Sulphate, a Metabolite of the Neurosteroid Pregnenolone, of Voltage-Gated Sodium Channels Expressed in Xenopus Oocytes

Journal of Pharmacological Sciences, 2012
Neurosteroids are known as allosteric modulators of the ligand-gated ion channel superfamily. Voltage-gated sodium channels (Nav) play an important role in mediating excitotoxic damages. Here we report the effects of neurosteroids on the function of Nav,

Molecular Diagnosis in Children With Febrile Seizures: Beyond the Conventional Clinical Classification

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Febrile seizures (FS) are currently classified as simple or complex primarily to describe seizure characteristics, with limited ability to identify the underlying etiology. We evaluated whether molecular diagnosis could complement conventional classification and improve the diagnosis and management of FS.
