Using Systolic Local Mechanical Load to Predict Fiber Orientation in Ventricles

Frontiers in Physiology, 2020
A simple rule adopted for myofiber reorientation in the ventricles is pursued by taking the microscopic branching network of myocytes into account.

Structure-based finite strain modelling of the human left ventricle in diastole [PDF]

, 2013
Finite strain analyses of the left ventricle provide important information on heart function and have the potential to provide insights into the biomechanics of myocardial contractility in health and disease. Systolic dysfunction is the most common cause

Post-traumatic hypoxia exacerbates neurological deficit, neuroinflammation and cerebral metabolism in rats with diffuse traumatic brain injury

Journal of Neuroinflammation, 2011
Background The combination of diffuse brain injury with a hypoxic insult is associated with poor outcomes in patients with traumatic brain injury. In this study, we investigated the impact of post-traumatic hypoxia in amplifying secondary brain damage ...

Morphology of the murine choroid plexus: Attachment regions and spatial relation to the subarachnoid space

Frontiers in Neuroanatomy, 2022
The choroid plexus has recently been identified as a possible migration route for peripheral immune cells into the central nervous system. For future investigation of this route, profound knowledge of the morphology of the murine choroid plexus is a ...

Left ventricular active stiffness: dependency on time and inotropic state [PDF]

, 1978
Left ventricular systolic stiffness was measured by rapidly changing ventricular volume (within 7 ms) of isovolumically contracting isolated rabbit hearts. Instantaneous pressure-volume relations were found to be linear with slopes that depended upon the

Detecção precoce da disfunção diastólica global e regional do ventrículo esquerdo no lúpus eritematoso sistêmico: o papel da ecocardiografia Early detection of global and regional left ventricular diastolic dysfunction in systemic lupus erythematosus: the role of the echocardiography

Revista Brasileira de Reumatologia, 2010
INTRODUÇÃO: A ecocardiografia bidimensional é um método de diagnóstico por imagem não invasivo que avalia, de modo eficaz, a função diastólica global e regional do ventrículo esquerdo.

Cardiovascular function and ballistocardiogram: a relationship interpreted via mathematical modeling [PDF]

, 2019
Objective: to develop quantitative methods for the clinical interpretation of the ballistocardiogram (BCG). Methods: a closed-loop mathematical model of the cardiovascular system is proposed to theoretically simulate the mechanisms generating the BCG ...

Association of Systemic Arterial Properties With Right Ventricular Morphology: The Multi‐Ethnic Study of Atherosclerosis (MESA)‐Right Ventricle Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
Background Systemic arterial stiffness is recognized as a major contributor to development of left ventricular dysfunction and failure; however, the relationship of systemic arterial properties and the right ventricle (RV) is unknown. Methods and Results

Reliability of Early Fetal Echocardiography for Congenital Heart Disease Detection: A Preliminary Experience and Outcome Analysis of 102 Fetuses to Demonstrate the Value of a Clinical Flow-Chart Designed for At-Risk Pregnancy Management [PDF]

, 2016
Early fetal echocardiography (EFEC) is a fetal cardiac ultrasound analysis performed between the 12th and 16th week of pregnancy (compared with the usual 18-22 weeks).
