Application of a strong FSI coupling scheme for the numerical simulation of bileaflet mechanical heart valve dynamics: study of wall shear stress on the valve leaflets [PDF]

, 2012
One of the major challenges in the design of Bileaflet Mechanical Heart Valves (BMHVs) is reduction of the blood damage generated by non-physiological blood flow.

Ultrasound‐Controlled Swarmbots Under Physiological Flow Conditions

Advanced Materials Interfaces, 2022
AbstractNavigation of microrobots in living vasculatures is essential in realizing targeted drug delivery and advancing non‐invasive surgeries. Acoustically‐controlled “swarmbots” are developed based on the self‐assembly of clinically‐approved microbubbles (MBs). Ultrasound is noninvasive, penetrates deeply into the human body, and is well‐developed in

Physiologically motivated multiplex Kuramoto model describes phase diagram of cortical activity [PDF]

, 2014
We derive a two-layer multiplex Kuramoto model from weakly coupled Wilson-Cowan oscillators on a cortical network with inhibitory synaptic time delays.

Physiological effects of high-flow oxygen in tracheostomized patients

Annals of Intensive Care, 2019
Background High-flow oxygen therapy via nasal cannula (HFOTNASAL) increases airway pressure, ameliorates oxygenation and reduces work of breathing. High-flow oxygen can be delivered through tracheostomy (HFOTTRACHEAL), but its physiological effects have ...

Isometric blood flow restriction exercise: acute physiological and neuromuscular responses

BMC Sports Science, Medicine and Rehabilitation, 2021
Background Numerous studies have demonstrated that the addition of blood flow restriction (BFR) to low-load (LL) resistance exercise leads to elevated levels of muscle hypertrophy and strength gains.

Physiological synchrony and shared flow state in Javanese gamelan: positively associated while improvising, but not for traditional performance

Frontiers in Psychology, 2023
The experience of shared flow refers to the optimal balance between challenge and ability for a given task, resulting from interpersonal action in a group situation.

Apical Medium Flow Influences the Morphology and Physiology of Human Proximal Tubular Cells in a Microphysiological System

Bioengineering, 2022
There is a lack of physiologically relevant in vitro human kidney models for disease modelling and detecting drug-induced effects given the limited choice of cells and difficulty implementing quasi-physiological culture conditions.

Pattern formation of reaction-diffusion system having self-determined flow in the amoeboid organism of Physarum plasmodium

, 1998
The amoeboid organism, the plasmodium of Physarum polycephalum, behaves on the basis of spatio-temporal pattern formation by local contraction-oscillators.

Meta-analysis of death and myocardial infarction in the DEFINE-FLAIR and iFR-SWEDEHEART trials: a hypothesis generating note of caution [PDF]

, 2017
In patients with coronary heart disease, revascularization can improve symptoms and in certain high-risk subgroups may improve prognosis. Coronary angiography provides anatomical information and the physiological significance of a stenosis can be ...
