Direct Estimation of Regional Wall Thicknesses via Residual Recurrent Neural Network [PDF]

arXiv, 2017
Accurate estimation of regional wall thicknesses (RWT) of left ventricular (LV) myocardium from cardiac MR sequences is of significant importance for identification and diagnosis of cardiac disease. Existing RWT estimation still relies on segmentation of LV myocardium, which requires strong prior information and user interaction.

Integrative Analysis of Calcium Cycling in Cardiac Muscle [PDF]

Circulation Research, 2000
Abstract —The control of intracellular calcium is central to regulation of contractile force in cardiac muscle. This review illustrates how analysis of the control of calcium requires an integrated approach in which several systems are considered.

Never in mitosis gene A related kinase-6 attenuates pressure overload-induced activation of the protein kinase B pathway and cardiac hypertrophy.

PLoS ONE, 2014
Cardiac hypertrophy appears to be a specialized form of cellular growth that involves the proliferation control and cell cycle regulation. NIMA (never in mitosis, gene A)-related kinase-6 (Nek6) is a cell cycle regulatory gene that could induce centriole

Reactivation of the mitosis-promoting factor in postmitotic cardiomyocytes [PDF]

, 2003
Cardiomyocytes cease to divide shortly after birth and an irreversible cell cycle arrest is evident accompanied by the downregulation of cyclin-dependent kinase activities.

UCP2 modulates cardiomyocyte cell cycle activity, acetyl-CoA, and histone acetylation in response to moderate hypoxia

JCI Insight, 2022
Developmental cardiac tissue is regenerative while operating under low oxygen. After birth, ambient oxygen is associated with cardiomyocyte cell cycle exit and regeneration. Likewise, cardiac metabolism undergoes a shift with cardiac maturation.

On in-silico estimation of left ventricular end-diastolic pressure from cardiac strains [PDF]

2024 46th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), pp. 1-4
Left ventricular diastolic dysfunction (LVDD) is a group of diseases that adversely affect the passive phase of the cardiac cycle and can lead to heart failure. While left ventricular end-diastolic pressure (LVEDP) is a valuable prognostic measure in LVDD patients, traditional invasive methods of measuring LVEDP present risks and limitations ...

Quantifying irregular pulsation of intracranial aneurysms using 4D-CTA [PDF]

Recent studies have suggested that irregular pulsation of intracranial aneurysm during the cardiac cycle may be potentially associated with aneurysm rupture risk. However, there is a lack of quantification method for irregular pulsations. This study aims

Tricuspid annulus: A spatial and temporal analysis

Annals of Cardiac Anaesthesia, 2016
Background: Traditional two-dimensional (2D) echocardiographic evaluation of tricuspid annulus (TA) dilation is based on single-frame measurements of the septolateral (S-L) dimension.

A characterization of cardiac-induced noise in R2* maps of the brain. [PDF]

Cardiac pulsation increases the noise level in brain maps of the transverse relaxation rate R ₂ *. Cardiac-induced noise is challenging to mitigate during the acquisition of R ₂ * mapping data because its ...
