Effect of Varying Viscosity on Two-Fluid Model of Blood Flow through Constricted Blood Vessels: A Comparative Study.
Tiwari A, Chauhan SS. Tiwari A, et al. Cardiovasc Eng Technol. 2019 Mar;10(1):155-172. doi: 10.1007/s13239-018-00379-x. Epub 2018 Oct 9. Cardiovasc Eng Technol. 2019. PMID: 30302623
PURPOSE: Most of the previously studied non-Newtonian blood flow models considered blood viscosity to be constant but for correct measurement of flow rate and flow resistance, the hematocrit dependent viscosity will be better as various literature suggested the vari …

A transthoracic Doppler echocardiography study of C-reactive protein and coronary microcirculation in children after open heart surgery.
Aburawi EH, Liuba P, Berg A, Pesonen E. Aburawi EH, et al. Cardiol Young. 2007 Oct;17(5):472-7. doi: 10.1017/S1047951107000972. Epub 2007 Jul 18. Cardiol Young. 2007. PMID: 17634161
In these children, we investigated whether the inflammatory mediator, C-reactive protein, could influence this association. METHODS: The peak flow velocity, velocity time-integral in diastole and systole, and basal blood flow in the proximal part of the left …

Micro-particle image velocimetry for velocity profile measurements of micro blood flows.
Pitts KL, Fenech M. Pitts KL, et al. J Vis Exp. 2013 Apr 25;(74):e50314. doi: 10.3791/50314. J Vis Exp. 2013. PMID: 23644696 Free PMC article.
A protocol is presented for muPIV measurements of blood flows in microchannels. At the scale of the microcirculation, blood cannot be considered a homogeneous fluid, as it is a suspension of flexible particles suspended in plasma, a Newtonian fluid. Shear rate, maxi …
