The carotid body as a putative therapeutic target for the treatment of neurogenic hypertension [PDF]

, 2013
In the spontaneously hypertensive (SH) rat, hyperoxic inactivation of the carotid body (CB) produces a rapid and pronounced fall in both arterial pressure and renal sympathetic nerve activity (RSA).

Corrected calculation of the overestimated ejection fraction in valvular heart disease by phase-contrast cardiac magnetic resonance imaging for better prediction of patient morbidity

The Egyptian Journal of Radiology and Nuclear Medicine, 2020
Background To establish a more accurate technique for the assessment of the left ventricular function correlated with patients’ clinical condition avoiding the miscalculation of the ejection fraction in valvular regurgitation. A prospective study carried

Derivation and validation of a model to predict acute kidney injury following cardiac surgery in patients with normal renal function

Renal Failure, 2021
Background The study aimed to construct a clinical model based on preoperative data for predicting acute kidney injury (AKI) following cardiac surgery in patients with normal renal function.

Learning the dynamics and time-recursive boundary detection of deformable objects [PDF]

, 2008
We propose a principled framework for recursively segmenting deformable objects across a sequence of frames. We demonstrate the usefulness of this method on left ventricular segmentation across a cardiac cycle.

What every ICU clinician needs to know about the cardiovascular effects caused by abdominal hypertension [PDF]

, 2015
The effects of increased intra-abdominal pressure (IAP) on cardiovascular function are well recognized and include a combined negative effect on preload, afterload and contractility.

Characterization of Left Ventricle Main Flow Axis Line Using Echodynamography

Indonesian Journal of Applied Physics, 2021
Left ventricular (LV) blood flow analysis may play an essential role in evaluating cardiac function besides the classical analysis of wall motion. Echodynamography is an imaging method in which two-dimensional (2D) blood flow vectors are deduced by blood

Regional differences in APD restitution can initiate wavebreak and re-entry in cardiac tissue: A computational study [PDF]

, 2005
Background Regional differences in action potential duration (APD) restitution in the heart favour arrhythmias, but the mechanism is not well understood.

Abnormalities in lysine degradation are involved in early cardiomyocyte hypertrophy development in pressure-overloaded rats

BMC Cardiovascular Disorders, 2021
Background Cardiomyocyte metabolism changes before cardiac remodeling, but its role in early cardiac hypertrophy detection remains unclear. This study investigated early changes in plasma metabolomics in a pressure-overload cardiac hypertrophy model ...

Site-Directed Mutagenesis and Site-Specific Binding Analysis of Calmodulin (CaM) [PDF]

, 2017
Calcium signaling is a major regulatory system in cells and a crucial part of cell biology. An important element in the decoding of intracellular calcium concentration into downstream processes is the ubiquitous and highly conserved calcium binding ...

Evolutionary Covariant Positions within Calmodulin EF-hand Sequences Promote Ligand Binding [PDF]

, 2018
Intracellular calcium signaling is an essential regulatory mechanism through calcium-mediated signal transduction pathways involved in many cell processes, such as exocytosis, motility, apoptosis, excitability, transcription, and muscle contraction.
