Left ventricle quantification through spatio-temporal CNNs [PDF]

arXiv, 2018
Cardiovascular diseases are among the leading causes of death globally. Cardiac left ventricle (LV) quantification is known to be one of the most important tasks for the identification and diagnosis of such pathologies. In this paper, we propose a deep learning method that incorporates 3D spatio-temporal convolutions to perform direct left ventricle ...

Regional Distribution of β‐Adrenoceptors in the Human Heart: Coexistence of Functional β1 and β2-Adrenoceptors in Both Atria and Ventricles in Severe Congestive Cardiomyopathy

, 1986
We evaluated the amount of β1- and β2-adrenoceptors in human right and left atrium as well as in right and left ventricular wall obtained from heart transplant recipients who suffered from end-stage congestive cardiomyopathy.

Regional Distribution of Glycogen and Phosphorylase in the Ventricles of the Heart

Circulation Research, 1964
In rat, rabbit, dog, and ox hearts, the glycogen concentration varied throughout the walls. The concentration gradient decreased from endocardium to epicardium in the right and left ventricles.

Berberine is a Novel Mitochondrial Calcium Uniporter Inhibitor that Disrupts MCU‐EMRE Assembly

Advanced Science, EarlyView.
Berberine, a safe and FDA‐approved drug, is identified as a novel mitochondrial calcium uniporter (MCU) inhibitor. By disrupting MCU‐EMRE interaction, Berberine prevents mitochondrial calcium overload and protects against ischemia/reperfusion injury, offering a promising therapeutic strategy for diseases linked to mitochondrial calcium dysregulation ...

A rare homozygous missense GDF2 (BMP9) mutation causing PAH in siblings: Does BMP10 status contribute?

American Journal of Medical Genetics Part A, Volume 191, Issue 1, Page 228-233, January 2023., 2023
Abstract Pulmonary arterial hypertension (PAH) is a disease characterized by pathological remodeling of the pulmonary vasculature causing elevated pulmonary artery pressures and ultimately, right ventricular failure from chronic pressure overload. Heterozygous pathogenic GDF2 (encoding bone morphogenetic protein 9 (BMP9)) variants account for some (>1%)

A Rare Case of Congenital Heart Disease with Bifid Car- diac Apex: A Unique Finding in Left Ventricle

Journal of Tehran University Heart Center, 2015
Bifid cardiac apex is a rare anomaly of human hearts. We report of the case of a 34-year-old man with a previous history of ventricular septal defect (VSD) and subvalvular pulmonary stenosis.

The Cerebrospinal Fluid Secretion Rate Increases in Awake and Freely Moving Rats but Differs With Experimental Methodology

Advanced Science, EarlyView.
CSF dynamics are vital for neurological health. Yet accurate quantification of CSF rates is challenging. Using a novel technique in awake, freely moving rats, significantly higher secretion rates are found than in anesthetized rats. The findings highlight the importance of awake models and the adaptability of methods for studying CSF changes influenced
