Perfusate composition and stability of polyribosomes in perfused liver
Life Sciences, 1972Abstract The polyribosomes in the resting liver from young adult rats are preserved during a one-hour perfusion in an isolated system with Krebs-Ringer bicarbonate buffer containing fresh rat blood (1:1, v/v) and glucose, only when both a high concentration of amino acids (e.g.

A simple modification of a patch-clamp set-up allows the fluid in a patch pipette to be changed. The time course of the solution exchange is estimated from the time course of change of the reversal potential of the current through an open Ca2+ activated K+ channel: solution exchange takes less than 1 min.

Digital Perfusion Phantoms for Visual Perfusion Validation
American Journal of Roentgenology, 2012Despite the increasingly broad use of perfusion applications, we still have no generally accessible means for their verification: The common sense of perfusion maps and "bona fides" of perfusion software vendors remain the only grounds for acceptance.

Automated CT perfusion imaging for acute ischemic stroke
Neurology, 2019Recent positive trials have thrust acute cerebral perfusion imaging into the routine evaluation of acute ischemic stroke. Updated guidelines state that in patients with anterior circulation large vessel occlusions presenting beyond 6 hours from time last

AbstractMeasurement of tissue perfusion is important for the functional assessment of organs in vivo. Here we report the use of 1H NMR imaging to generate perfusion maps in the rat brain at 4.7 T. Blood water flowing to the brain is saturated in the neck region with a sliceselective saturation imaging sequence, creating an endogenous tracer in the form

Magnetic Particle Imaging for Real-Time Perfusion Imaging in Acute Stroke.
ACS Nano, 2017The fast and accurate assessment of cerebral perfusion is fundamental for the diagnosis and successful treatment of stroke patients. Magnetic particle imaging (MPI) is a new radiation-free tomographic imaging method with a superior temporal resolution ...

The term perfusion has varied connotations in different situations. The word perfusion comes from the Latin to pour or diffuse through or over. Myocardial perfusion depends on (a) coronary artery or vessel flow, and (b) myocardial or muscle flow.

Aortic arch surgery necessitates interrupted brain perfusion and carries a risk of brain injury. Various brain protective techniques have been advocated to reduce risk including hypothermic arrest and retrograde or selective antegrade perfusion. Knowledge of the pathophysiologic consequences of deep hypothermia, may aid the surgeon in deciding when to ...
