Abstract

Multiple approaches are available to measure global and regional cerebral blood flow. The inert gas method of Kety-Schmidt provides the mathematical basis for essentially all of these methods with the exception of microspheres. The preferred method depends largely upon the type of information to be obtained. The preferred method depends largely upon the type of information to be obtained. The three essential problems in cerebral blood flow measurement are establishing reliable cerebral blood flow measurements in pathological processes, the relation of this flow to metabolism, and the clinical application of cerebral blood flow measurements in man for the investigation of a wide variety of significant disease processes including ischemia and intracranial hypertension.

Autoimmune Polyendocrine Syndromes

This feed focuses on a rare genetic condition called Autoimmune Polyendocrine Syndromes, which are characterized by autoantibodies against multiple endocrine organs. This can lead to Type I Diabetes.

Autoimmune Polyendocrinopathies

Autoimmune polyendocrinopathies, also called polyglandular autoimmune syndromes (PGASs), or polyendocrine autoimmune syndromes(PASs), are a heterogeneous group of rare diseases characterized by autoimmune activity against more than one endocrine organ, although non-endocrine organs can be affected. Discover the latest research on autoimmune polyendocrinopathies here.
