Current Opinion in Cardiology, 1994
The focus of the reports reviewed in the last year has shifted to "outcomes," perhaps in response to the pressures of national health care reform. With regards to the extracorporeal circulation requisite for complex cardiac repair, emphasis is placed on anticoagulation management, blood use and its systemic effects, cognitive outcome after cardiac ...

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.

AbstractLocal driving pressures and resistances within the pulmonary vascular tree determine the distribution of perfusion in the lung. Unlike other organs, these local determinants are significantly influenced by regional hydrostatic and alveolar pressures.

ABSTRACT Thyroid glands maintained by isolated perfusion have been used for studies in metabolism, micro-circulation and tumour angiogenesis. Recent work is described. Thyroid metabolism can be studied for brief periods of 4–5 hours, after which there is progressive parenchymal damage.

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

MRI has become a reliable tool in medical imaging for assessing morphological and functional details of the human body in a noninvasive manner. Perfusion is an important parameter to assess status and functionality of tissue and organs. This review summarizes the different approaches to measure perfusion based on MRI.

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 ...
