Development of an efficient mice model of cancer‐associated cardiac cachexia

Animal Models and Experimental Medicine, EarlyView.
This work establishes a preclinical framework for targeting ubiquitin pathways to mitigate the morbidity of cancer‐related cardiopathy. Our integrated approach delineates a hierarchical progression from subcellular dysfunction to macroscopic cardiac deterioration. These findings mechanistically link tumor‐induced cachexia to cardiac dysfunction through

Changes in hemodynamics of pulmonary artery using Flowire in a canine model of acute pulmonary thromboembolism

Animal Models and Experimental Medicine, EarlyView.
This study investigated changes in pulmonary artery hemodynamics using a Flowire catheter and evaluated the accuracy of Doppler echocardiography in dogs with acute pulmonary thromboembolism (PTE). Ten healthy beagles were anesthetized, and acute pulmonary hypertension (PH) was induced by injecting 300‐μm dextran microspheres.

Exenatide Once Weekly in the Treatment of Patients with Multiple System Atrophy

Annals of Neurology, EarlyView.
Objective Exenatide, a glucagon‐like peptide‐1 (GLP‐1) receptor agonist, has neuroprotective effects in preclinical models of multiple system atrophy (MSA). We investigated these effects in a proof‐of‐concept clinical trial. Methods In this single‐center, randomized, open label trial, participants with MSA were randomly assigned (1:1) to receive ...

Disease Progression in Multiple System Atrophy: The ASPIRE Multi‐Modal Biomarker Study

Annals of Neurology, EarlyView.
Objective The objective of this study was to characterize changes in candidate biomarkers in early multiple system atrophy (MSA) and identify baseline predictors of faster progression. Methods This 1‐year, multicenter, prospective study assessed clinical, neuroimaging (3T‐magnetic resonance imaging [MRI], dopamine transporter single‐photon emission ...

Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

The Anatomical Record, EarlyView.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.

Morphological and morphometric aspects of the equine aortic valve: New insights for comparative studies in mammals

The Anatomical Record, EarlyView.
Abstract New data on the equine aortic valve obtained using advanced techniques is especially important given the greater availability of animal models for translational research. Here we characterized the morphological and morphometric aspects of the equine aortic valve from 60 healthy hearts collected at equine abattoirs.
