An intracellular recombinant single‐chain variable antibody fragment as a new class of phosphodiesterase type 5 inhibitors

British Journal of Pharmacology, EarlyView.
Background and Purpose Cyclic guanosine monophosphate (cGMP) is a ubiquitous second messenger involved in human (patho‐)physiology. Phosphodiesterase 5 (PDE5) is a major cGMP hydrolyzing enzyme in many cell types including vascular smooth muscle cells (VSMCs). Several highly selective PDE5 inhibitors are in clinical use. However, there are currently no

Variable electrophysiology before and after block of the two delayed rectifier potassium channels in groups of isolated rabbit ventricular cells

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Between‐cell differences in ventricular cardiomyocyte action potential duration (APD) and responses to ion channel block may contribute to pro‐arrhythmic dispersion of myocardial repolarisation. This study quantifies between‐cell physiological and pharmacological variability in the rabbit left ventricle (LV) and uses ...

Metabolomic profiling of pheochromocytomas in dogs: Catecholamine phenotype and tricarboxylic acid cycle metabolites

Journal of Veterinary Internal Medicine
Background In humans with pheochromocytomas (PCCs), targeted metabolomics is used to determine the catecholamine phenotype or to uncover underlying pathogenic variants in tricarboxylic acid (TCA) cycle genes such as succinate dehydrogenase subunits (SDHx)

A novel selective stabilizer of the ryanodine receptor 2 prevents stress‐induced ventricular arrhythmias without impairing cardiac function

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Aberrant activation of type 2 ryanodine receptors (RyR2) causes lethal arrhythmias, such as catecholaminergic polymorphic ventricular tachycardia (CPVT). Developing drugs that suppress RyR2 hyperactivation may be key to novel arrhythmia treatments.

Diltiazem N‐oxide, a novel ischaemia‐activated prodrug, prevents ischaemia‐induced ventricular fibrillation without off‐target adverse effects

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Ventricular fibrillation (VF) in coronary heart disease accounts for up to 70% of sudden cardiac death. We examined whether diltiazem N‐oxide (DNO) has ischaemia‐selective antiarrhythmic activity. Experimental Approach Randomised and blinded experiments were performed in rat isolated hearts and in anaesthetised rats to ...

Toll‐like receptor 4 mediates lipopolysaccharide‐induced emesis

British Journal of Pharmacology, EarlyView.
Background and Purpose Lipopolysaccharide (LPS) induces inflammation and sepsis through Toll‐like receptor 4 (TLR4) activation. Common laboratory animals do not exhibit emesis, but administration of LPS in piglets, cats, and dogs induces emesis via peripheral mechanisms.

Photoperiod‐Regulated Thermal Tolerance of the Non‐Diapausing Insect Ceratitis capitata (Diptera: Tephritidae)

Entomologia Experimentalis et Applicata, EarlyView.
Developmental photoperiodic exposure (photoacclimation) from egg to adult emergence alters thermal tolerance in Ceratitis capitata. Flies reared under contrasting photoperiods (0:24, 8:16, 14:10, and 24:0 L:D) showed significant shifts in both CTmin and CTmax, whereas adult‐only photoacclimation affected CTmax but not CTmin.
