Electrical Storm Induced by Cardiac Resynchronization: Efficacy of the Multipoint Pacing Stimulation.

Although cardiac resynchronization therapy (CRT) reduces morbidity and mortality and reverses left ventricular (LV) remodeling in heart failure patients with LV electrical dyssynchrony, induced proarrhythmia has been reported. The mechanism of CRT-induced proarrhythmia remains under debate. In this case report, a description of how LV pacing induced polymorphic ventricular tachycardia immediately after the initiation of CRT has been reported.

Plasma cell-free DNA concentration increases during luteolysis in beef cows.

During cell death, DNA is fragmented and reaches the bloodstream in the form of cell-free DNA (cfDNA). Luteal cells must undergo an apoptotic process during structural luteolysis to begin a new oestrous cycle. We hypothesized that cfDNA concentrations would increase when inducing luteolysis by applying prostaglandin F (PGF2α) analog to the cycling cow.

Long-acting injectable formulation technologies: challenges and opportunities for the delivery of fragile molecules.

Introduction: The development of long-acting injectables (LAIs) for protein and peptide therapeutics has been a key challenge over the last 20 years. If these molecules offer advantages due to their high specificity and selectivity, their controlled release may confer several additional benefits in terms of extended half-life, local delivery, and patient compliance.

Area Covered: This manuscript aims to give an overview of peptide and protein-based LAIs from an industrial perspective, describing both approved and promising technologies (with exceptions of protein engineering strategies and devices), their advantages and potential improvements to aid their access to the market.
