Reduced longitudinal cardiac strain in asthma patients
Journal of Asthma, 2018There is limited knowledge about the potential relationship between asthma and heart function. Aim of our present study was to examine if asthma may be associated with manifest or subclinical heart dysfunction.Seventy-two allergic mild-to-moderate and severe asthma patients and 20 matched controls were enrolled in the study.

Longitudinal and radial strain in pulse wave transmission
American Journal of Physiology-Legacy Content, 1961Simultaneous measurements of changes in aortic length, circumference and pressure reveal that at the beginning of systole aortic lengthening precedes the increased aortic circumference and pressure. Slight differences which were observed between circumference and pressure may be accounted for by longitudinal motion and by instrumental artifacts.

Impaired left ventricular (LV) longitudinal function (LF) is a known predictor of cardiac events in patients with heart failure, but two-dimensional strain imaging, the reference method to measure myocardial deformation, is not always feasible or available. Therefore, reliable and reproducible alternatives are needed.

Strain imaging is a robust clinical tool in cardiac surveillance of patients with breast cancer. However, image quality and therefore ability to accurately measure strain are often limited in this patient group because of tissue expanders, implants, and/or flap reconstruction.

Longitudinal Residual Strains in Coronary Arteries
ASME 2009 Summer Bioengineering Conference, Parts A and B, 2009Constitutive formulation is fundamental to the study of vascular mechanics. A robust and accurate constitutive model can aid in the design of tissue engineered grafts or provide insights for growth and remodeling studies. Strains in constitutive model are defined with reference to a stress-free configuration.

Longitudinal behavior of strain gradient bars
International Journal of Engineering Science, 2013Abstract In this paper, the strain gradient theory, a non-classical continuum theory capable of capturing the size effect observed in micro-scale structures, is employed in order to investigate the size-dependent mechanical behavior of microbars. For a strain gradient bar, the governing equation of motion and classical and non-classical boundary ...

Longitudinal strain enhancement and bending deformations in piezoceramics
NaturePiezoelectric materials directly convert between electrical and mechanical energies. They are used as transducers in applications such as nano-positioning and ultrasound imaging. Improving the properties of these devices requires piezoelectric materials capable of delivering a large longitudinal strain on the application of an electric field.

Background: Patients with significant overcirculation from large ventricular septal defects (VSDs) may have altered contractility compared to normal patients. Methods: Patients were enrolled prospectively. Patients were excluded if they were acutely ill or over age five.

Longitudinal Growth Strains in Melia dubia
2017Logs of many fast-grown tree species develop end splitting immediately after felling, and timber from such logs suffers from excessive warping and twisting on sawing. Such distortions are attributed to the presence of high magnitude of inherent growth stresses.
