Acid reflux, gas and heartburn can be caused by a misaligned spine. The nerves running through the thoracic area of the spine control the stomach functions and can cause these and other digestive disorders. When a chiropractor adjusts your spine, the nerve flow to the stomach is aligned which...
Through experiments and simulations, the researchers examined the common assumption of disordered blood flow, and found that a healthy red blood cell is rather soft and flexible. When red blood cells are hardened in diseases such as sickle cell anemia, however, that order is suppressed. "Red blo...
innovations in histochemistry have revealed that even higher branch order pericytes express this contractile protein [3] and optogenetic experiments have shown that these higher branch order pericytes can also regulate capillary diameter and blood flow [www.biorxiv.org/content/10.1101/2020.03.26.008763v1...
At each of the 20 force levels, the 5 s of recording allows for approximately 3–7 complete pulses of blood flow, as measured by the pixel intensity of the pinhole projection. For each of these force levels, we applied a 0.5–10 Hz band pass filter and then averaged the peak-to-...
blood flow, vascular development and maintenance, and neuroinflammation.85,86,87 Tight junctions In the BBB, tight junctions are the main functional components in sustaining the permeability barrier and controlling tissue homeostasis.88,89,90,91They are also known as occluding junctions or zonulae ...
We present a well-balanced, high-order non-linear numerical scheme for solving a hyperbolic system that models one-dimensional flow in blood vessels with variable mechanical and geometrical properties along their length. Using a suitable set of test problems with exact solution, we rigorously assess...
Blood oxygen level-dependent (BOLD) fMRI of sleep provides unique opportunities to investigate brain function across a range of arousal states. fMRI relies on the blood flow (hemodynamic) response to local cortical circuit activity [1•], involving the so-called ‘neurovascular’ unit, in which...
In order to simplify the equations for mathematical analysis, for this work, attention is focused on cases where it is appropriate to model the flow as quasi-steady and the wall motion does not have a significant impact on bulk flow parameters. This work lays the foundation for future ...
Second, green PPG is good at capturing capillary blood flow and perfusion at the level of skin, whereas IR PPG is more suited for capturing blood flow and perfusion deep under the skin (where relatively large arteries are often located)40. Hence, green PPG may possess superior signal quality...
Thermal enhancement and numerical solution of blood nanofluid flow through stenotic artery ArticleOpen access19 October 2022 Introduction In order to understand how hemodynamics factors effects the atherosclerotic disease FSI study is considered as powerful tool. FSI combines the wall stress with blood flo...
