Neutrophil–Endothelium Interaction Mediated by S100A9 Promotes Pulmonary Vascular Remodeling During Pulmonary Hypertension

Advanced Science, EarlyView.
This study investigates the critical mechanisms underlying pulmonary hypertension progression, with a focus on the novel role of neutrophil‐derived S100A9 in endothelial dysfunction‐mediated pulmonary vascular remodeling. By integrating human lung samples, multi‐omics analyses, animal models, and mechanistic in vitro studies, it is revealed that how ...

Inter-observer variability for cardiac ultrasound measurements in cats repeated at different time points in early adult life [PDF]

, 2018
A high degree of accuracy is required when using echocardiography to diagnose hypertrophic cardiomyopathy (HCM) in cats, as variation in measurements of 0.5 mm may affect classification of individuals as ‘abnormal’.

Echocardiography: An overview

Journal of the American College of Cardiology, 1983
In the past 25 to 30 years echocardiography has become a basic examination in clinical cardiology. Thus, it is becoming increasingly necessary for clinicians to be able to utilize it intelligently. Like all medical procedures echocardiography has advantages and limitations, and physicians need to know both.

Activation of Spinal Astrocyte α2A Adrenoceptors Protects Against Sepsis‐Induced Heart Injury Through Inhibition of GABAergic Neuronal Necroptosis

Advanced Science, EarlyView.
The study in this paper found that activating the α2A receptors of astrocytes in the thoracic spinal cord can reduce the release of inflammatory factors, thereby decreasing the necroptosis of GABAergic neurons and consequently alleviating myocardial injury caused by sepsis.

ER‐phagy Activation by AMFR Attenuates Cardiac Fibrosis Post‐Myocardial Infarction via mTORC1 Pathway

Advanced Science, EarlyView.
By catalyzing FAM134B ubiquitination and activating ER‐phagy, AMFR alleviates progressive fibrosis and cardiac dysfunction by inhibiting the mTORC1 pathway. Consequently, these findings underscore the essential role of AMFR‐driven ER‐phagy in mitigating the progression of fibrotic responses, offering a potential therapeutic target for preventing heart ...

Symptomatic giant left atrial aneurysm in a child : a rare entity [PDF]

, 2010
Isolated left atrial aneurysms are rare entities in clinical practice. Usually the condition is diagnosed in the second to fourth decades of life. The presence of such lesions in the pediatric age group is scantily described.

Anti‐Icing Organogel Enables Quasi‐Homogeneous Supercooling Preservation of Mouse Hearts

Advanced Science, EarlyView.
An organogel interface with a large energy barrier for ice nucleation is proposed to enable a quasi‐homogeneous supercooling preservation for organs. This method does not rely on cryoprotectant agents or machine perfusion and can double the ex vivo storage time of mouse hearts.
