Microminipig, a Non-rodent Experimental Animal Optimized for Life Science Research: In Vivo Proarrhythmia Models of Drug-Induced Long QT Syndrome: Development of Chronic Atrioventricular Block Model of Microminipig

Journal of Pharmacological Sciences, 2011
A new in vivo proarrhythmia model of drug-induced long QT syndrome was developed using the Microminipig, an incredibly small minipig established by Fuji Micra Inc. (Shizuoka).

Full‐Spectrum Medicinal Cannabis Plant Extract 0.08% THC (NTI164) Improves Symptoms of Rett Syndrome: An Open‐Label Study

Journal of Paediatrics and Child Health, EarlyView.
ABSTRACT Aim The aim of this Phase I/II open‐label study was to assess the safety and efficacy of NTI164, a novel full‐spectrum medicinal cannabis plant extract 0.08% Δ‐9‐tetrahydrocannabinol (THC), in Rett syndrome (RTT). Methods Eleven female participants (5–16 years) with a pathogenic variant in the MECP2 gene were recruited to this study, receiving

Acute Hypokalemia May Not Be an Effective Way to Sensitize the In Situ Canine Heart for Sparfloxacin-Induced Long QT Syndrome

Journal of Pharmacological Sciences, 2006
.: Extents of the sparfloxacin (3 – 10 mg/kg, i.v.)-induced QT interval prolongation under normokalemic and hypokalemic conditions were assessed in halothane-anesthetized beagle dogs (n = 5).

Characterisation of sleep apneas and respiratory circuitry in mice lacking CDKL5

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary CDKL5 deficiency disorder is a rare genetic disease caused by mutations in the CDKL5 gene. Central apneas during wakefulness have been reported in patients with CDKL5 deficiency disorder. Studies on CDKL5‐knockout mice, a CDKL5 deficiency disorder model, reported sleep apneas, but it is still unclear whether these events are central (central ...

Suppression of premature ventricular complexes with the PDE5 inhibitor sildenafil: First clinical experience

Experimental Physiology, EarlyView.
Abstract The phosphodiesterase‐5 inhibitor sildenafil suppresses ventricular arrhythmias in a sheep model of drug‐induced long QT. In that study, ventricular arrhythmias were abolished by reducing premature ventricular complexes (PVCs) and delaying PVC onset, thus preventing ‘R‐on‐T’ ventricular tachycardia.

Cardiac‐specific Kv1.1 deficiency alters cardiomyocyte electrophysiology without modifying overall cardiac function or arrhythmia susceptibility

Experimental Physiology, EarlyView.
Abstract The leading cause of epilepsy‐related mortality is sudden unexpected death in epilepsy (SUDEP), resulting from seizure‐induced cardiorespiratory arrest by mechanisms that remain unresolved. Mutations in ion channel genes expressed in both brain and heart represent SUDEP risk factors because they can disrupt neural and cardiac rhythms ...

Congenital Short QT Syndrome

Indian Pacing and Electrophysiology Journal, 2004
Long QT intervals in the ECG have long been associated with sudden cardiac death. The congenital long QT syndrome was first described in individuals with structurally normal hearts in 1957.1 Little was known about the significance of a short QT ...

Cardiac Events During Competitive, Recreational, and Daily Activities in Children and Adolescents With Long QT Syndrome

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundThe 2005 Bethesda Conference Guidelines advise patients with long QT syndrome against competitive sports. We assessed cardiac event rates during competitive and recreational sports, and daily activities among treated long QT syndrome patients ...
