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...
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-...
Speckle contrast imaging is an established technique to obtain relative blood flow maps over wide fields of view. A major improvement of the method relies on the acquisition of raw speckle images at different exposure times but requires simultaneous modulation of a laser pulse in duration and intens...
The coagulation process is inhibited by nonspecific mechanisms such as blood flow and by the presence in plasma of general serine protease inhibitors such as alpha2-macroglobulin. In addition, unique molecular systems will specifically inhibit blood coagulation and one of these involves heparin, a sulf...
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...
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...
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 ...
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 ...
The ICG time series is the first-order time derivative of the bioimpedance signal, dZdt. As blood is a conductor, each heart beat produces a change in electrical impedance66. Therefore, the ICG signal has been shown to depend on haemodynamic parameters related to blood flow such as PEP66. ...
