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

The physiology of left ventricular pressure fall.

Revista portuguesa de cardiologia : orgao oficial da Sociedade Portuguesa de Cardiologia = Portuguese journal of cardiology : an official journal of the Portuguese Society of Cardiology, 2000
Left ventricular pressure (LVP) fall is the hemodynamic manifestation of myocardial relaxation. This paper reviews the most important aspects of LVP fall and its regulation by load, inactivation and nonuniformity. This regulation is explained in terms of calcium transients and cross-bridge mechanics.

From Rigid to Soft Robotic Approaches for Neuroendoscopy

Advanced Robotics Research, EarlyView.
Robotic assistance has had minimal impact on deep intraventricular surgeries, where small‐scale, precision, and reduced invasiveness can contribute to improved patient outcomes. Emerging technologies in rigid, soft, and hybrid robotics are reviewed to identify the most promising mechanisms for deep brain navigation in addition to an attempt to identify

Thyroid hormone levels within reference range are associated with heart rate, cardiac structure, and function in middle-aged men and women [PDF]

, 2013
Background: Triiodothyronine (T3) has many effects on the heart, and marked changes in cardiac function and structure occur in patients with (subclinical) thyroid disease. We investigated whether between-subject variation in thyroid hormone levels within
