Nature has been unusually kind to research scientists who work with the catecholamines: it has endowed their work with instant relevance. In few other areas of biomedical science has it been possible ...

The catecholamines epinephrine and norepinephrine are neurotransmitter stress hormones that influence cardiac function profoundly. We and others have shown that the heart itself produces these ...

The abnormality in catecholamine metabolism has now been further explored by measurement of the catecholamine content of the adrenal glands and heart muscle of children dying with dysautonomia. The ...

The aim of this study was to assess the influence of anxiety and plasma catecholamines on the pharmaco-induced erection of psychogenic erectile dysfunction (ED) patients. A total of 23 patients with ...

Catecholamine urine testing (CATU) is used to diagnose certain diseases that increase catecholamine production. The test is often combined with a catecholamine blood test. Levels can fluctuate, so ...

Renalase is a relatively recently discovered kidney protein connected to chronic kidney disease and blood pressure disorders. It functions by metabolizing catecholamines and similar substances, such ...

Pheochromocytomas are neural crest-derived tumors that produce catecholamines, such as epinephrine and norepinephrine, and arise mainly from the adrenal gland. Closely affiliated tumors of ...
