Aerobic exercise training increases cerebral blood flow in postmenopausal women
Artery Research, 2012 Background: Age-related decrease in cerebral blood flow is a risk factor for cognitive decline. Aerobic exercise training improves vascular and cognitive functions.

Abnormal Cerebrovascular Reactivity in Patients with Parkinson’s Disease
Parkinson's Disease, 2015 Background. Orthostatic hypotension (OH) is an important nonmotor manifestation of Parkinson’s disease (PD). Changes in cerebrovascular reactivity may contribute to this manifestation and can be monitored using transcranial Doppler. Objective.

Evaluation of arterial digital blood flow using Doppler ultrasonography in healthy dairy cows
BMC Veterinary Research, 2017 Background Local circulatory disturbances have been implicated in the development of foot disorders in cattle. The goals of this study were to evaluate the suitability of the interdigital artery in the pastern region in both hind limbs using pulsed-wave (

Comparison of reduced models for blood flow using Runge-Kutta discontinuous Galerkin methods
, 2016 One-dimensional blood flow models take the general form of nonlinear hyperbolic systems but differ greatly in their formulation. One class of models considers the physically conserved quantities of mass and momentum, while another class describes mass ...

Numerical-experimental observation of shape bistability of red blood cells flowing in a microchannel [PDF]
, 2017 Red blood cells flowing through capillaries assume a wide variety of different shapes owing to their high deformability. Predicting the realized shapes is a complex field as they are determined by the intricate interplay between the flow conditions and ...
