Technical characteristics of laser Doppler flowmetry (LDF), Laser Speckle Contrast Imaging (LSCI) and Tissue Viability Imaging (TiVi).

, 2015
LDF: laser Doppler flowmetry, LSCI: laser speckle contrast imaging, TiVi: Tissue Viability Imaging, fps: frames per second.* since LDF measures perfusion in a single-point, the spatial resolution (distance between adjacent measurement points) is not ...

Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers

The Canadian Journal of Chemical Engineering, EarlyView.
This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Assessment of Regional Myocardial Displacement via Spectral Tissue Doppler Compared with Color Tissue Tracking [PDF]

Journal of Tehran University Heart Center, 2008
Background: The recent developments in tissue Doppler imaging (TDI) now more than ever permit the quantification of the myocardial function. In the current systems, tissue tracking or displacement curves are generated from color tissue Doppler data ...

Effect of arrhythmias on tissue Doppler velocities

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2018
Sa wave of tissue Doppler imaging correlates with ventricular systole (QRS-T of electrocardiogram). Ea wave correlates with ventricular filling in early diastole. Aa wave correlates with ventricular filling during atrial contraction and correlates with P

Prevalence of transthyretin cardiac amyloidosis in undifferentiated heart failure with preserved ejection fraction

ESC Heart Failure, Volume 12, Issue 2, Page 1176-1182, April 2025.
Abstract Aims Transthyretin amyloid cardiomyopathy (ATTR‐CM) is an increasinglyrecognized cause of heart failure with preserved ejection fraction (HFpEF), which may be diagnosed non‐invasively using 99mTc 3,3‐diphosphono‐1,2‐propanodicarboxylic acid (DPD) scintigraphy‐based diagnostic criteria.

Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.
