A novel roller pump for physiological flow [PDF]

open access: yesArtificial Organs, 2020
AbstractHaving physiological correct flow waveforms is a key feature for experimental studies of blood flow, especially in the process of developing and testing a new medical device such as stent, mechanical heart valve, or any implantable medical device that involves circulation of blood through the device.

Physiologic blood flow is turbulent [PDF]

open access: yesScientific Reports, 2020
AbstractContemporary paradigm of peripheral and intracranial vascular hemodynamics considers physiologic blood flow to be laminar. Transition to turbulence is considered as a driving factor for numerous diseases such as atherosclerosis, stenosis and aneurysm.

Heat Transfer Attributes of Gold–Silver–Blood Hybrid Nanomaterial Flow in an EMHD Peristaltic Channel with Activation Energy

open access: yesNanomaterials, 2022
The heat enhancement in hybrid nanofluid flow through the peristaltic mechanism has received great attention due to its occurrence in many engineering and biomedical systems, such as flow through canals, the cavity flow model and biomedicine.

Endothelial Cell Targeting by cRGD-Functionalized Polymeric Nanoparticles under Static and Flow Conditions

open access: yesNanomaterials, 2020
Since αvβ3 integrin is a key component of angiogenesis in health and disease, Arg-Gly-Asp (RGD) peptide-functionalized nanocarriers have been investigated as vehicles for targeted delivery of drugs to the αvβ3 integrin-overexpressing neovasculature of ...

Physiological non-Newtonian blood flow through single stenosed artery [PDF]

open access: yesTheoretical and Applied Mechanics, 2016
A numerical simulation to investigate the Non-Newtonian modeling effects on physiological flows in a three dimensional idealized artery with a single stenosis of 85% severity is given. The wall vessel is considered to be rigid.

Physiologic Data-Driven Iterative Learning Control for Left Ventricular Assist Devices

open access: yesFrontiers in Cardiovascular Medicine, 2022
Continuous flow ventricular assist devices (cfVADs) constitute a viable and increasingly used therapy for end-stage heart failure patients. However, they are still operating at a fixed-speed mode that precludes physiological cfVAD response and it is ...

On the physiology of flow: Bridging flow theory with the biopsychosocial model of challenge and threat

open access: yesInternational Journal of Psychophysiology, 2022
We examined the relation between psychological flow and cardiovascular markers of challenge. According to flow theory and the biopsychosocial model of challenge and threat (BPS-CT) optimal motivational states (flow, challenge) arise during activities where task demands meet personal resources. Participants (N = 154) played Tetris in either an underload,

Induction and characterization of tetraploid pear from the seeds of 'Dangshansuli' (Pyrus bretschneideri Rehd.)

open access: yesFruit Research, 2023
Pear is one of the most economically important fruit crops widely distributed around the world. To enrich the pear germplasm resources for obtaining the polyploid plants, the seeds from pear cultivar of 'Dangshansuli' (Pyrus bretschneideri) were treated ...
