Anatomy and physiology of coronary blood flow [PDF]

Journal of Nuclear Cardiology, 2010
Regional myocardial blood flow can now be measured noninvasively in units of milliliters blood per minute per gram myocardium. These noninvasive measurements are not confined to a specific imaging modality but are available with MRI, CT, and PET, although, thus far, most investigations of the coronary circulation in humans have employed PET flow ...

Physiological flow of Carreau fluid due to ciliary motion

AIP Advances, 2016
In this paper, we have explained the ciliary motion of a Carreau fluid inside a symmetrical channel with ciliated walls. Carreau fluid equations for the two dimensional channel are interpreted by employing the low Reynolds number and long wave-length ...

Contribution of flow state to the discrepancy between perceived exercise intensity and physiological intensity during endurance bike exercise

BMC Sports Science, Medicine and Rehabilitation
Background The flow phenomenon, achieving a heightened state of concentration, is characterized by an autotelic experience, which may reduce the perception of physical exertion during sports activities. It has been extensively documented in sports and is

Modelling the Balance Axiom in Flow Theory: A Physiological and Computational Approach in STEAM Education

Sensors
This paper addresses the axiom of balance in Flow Theory from a physiological-and-group-based approach by a quasi-experimental study using mixed methods across two action–research cycles, each divided into pre-test, intervention, and post-test phases ...

Physiological shear flow enhances pinocytosis in human platelets

Scientific Reports
Pinocytosis, the uptake of extracellular fluid, is an important yet poorly understood function of platelets. Although platelets are continuously exposed to shear flow in the circulation, the mechanism by which shear modulates pinocytosis in human ...

Effect of Varying Hemodynamic and Vascular Conditions on Fractional Flow Reserve: An In Vitro Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundThe aim of this study was to investigate the impact of varying hemodynamic conditions on fractional flow reserve (ratio of pressure distal [Pd] and proximal [Pa] to stenosis under hyperemia) in an in vitro setting.

User-friendly microfluidic system reveals native-like morphological and transcriptomic phenotypes induced by shear stress in proximal tubule epithelium

APL Bioengineering, 2023
Drug-induced nephrotoxicity is a leading cause of drug attrition, partly due to the limited relevance of pre-clinical models of the proximal tubule. Culturing proximal tubule epithelial cells (PTECs) under fluid flow to mimic physiological shear stress ...

Monitoring of sap flow, leaf water potential, stomatal conductance, and latex yield of rubber trees under irrigation management [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2008
To investigate the physiological responses and latex yield of rubber trees under irrigation management, an experiment was established at Songkhla Province, southern Thailand. The sap flow of rubber trees was measured by heat-pulse technique.
