Cerebral blood flow velocity is associated with endothelial function in men [PDF]
Journal of Men's Health, 2021 Background and objective: Reduction in cerebral blood flow with aging leads to cognitive decline and brain atrophy. Cerebrovascular hemodynamics are associated with vascular function.

Calibration-free in vivo transverse blood flowmetry based on cross correlation of slow time profiles from photoacoustic microscopy [PDF]
, 2013 We propose a cross-correlation-based method to measure blood-flow velocity by using photoacoustic microscopy. Unlike in previous autocorrelation-based methods, the measured flow velocity here is independent of particle size.

Hidden fluid mechanics: Learning velocity and pressure fields from flow visualizations
Science, 2020 Machine-learning fluid flow Quantifying fluid flow is relevant to disciplines ranging from geophysics to medicine. Flow can be experimentally visualized using, for example, smoke or contrast agents, but extracting velocity and pressure fields from this ...

In vivo photoacoustic flowmetry in the optical diffusive regime based on saline injection [PDF]
, 2016 We propose a saline-injection-based method to quantify blood flow velocity in vivo with acoustic-resolution photoacoustic tomography. By monitoring the saline-blood-interface propagating in the blood vessel, we can resolve the flow velocity.

The Effects of Involuntary Respiratory Contractions on Cerebral Blood Flow during Maximal Apnoea in Trained Divers. [PDF]
PLoS ONE, 2013 The effects of involuntary respiratory contractions on the cerebral blood flow response to maximal apnoea is presently unclear. We hypothesised that while respiratory contractions may augment left ventricular stroke volume, cardiac output and ultimately ...

Inert gas clearance from tissue by co-currently and counter-currently arranged microvessels [PDF]
, 2012 To elucidate the clearance of dissolved inert gas from tissues, we have developed numerical models of gas transport in a cylindrical block of tissue supplied by one or two capillaries. With two capillaries, attention is given to the effects of co-current
