These studies demonstrated the existence of chromaffin-reacting granules in the human skin. The chromaffin reaction was provided by bichromate fixation. Subsequent special staining by the modified ...

Cells send electrical impulses throughout the body, but electrophysiologists struggled to tune into these signals until the ...

We're also establishing a large database of patients with Cushing syndrome and expanding our basic science research to study the role of molecular genetics in the development of tumors arising from ...

Figure 1: Diagram of a chromaffin cell, showing the relative distribution of secretory granules, mitochondria and endoplasmic reticulum (ER).

The 2004 WHO classification of endocrine tumors defines pheochromocytoma as a tumor arising from catecholamine-producing chromaffin cells in the adrenal medulla -- an intra-adrenal paraganglioma.

Using chromaffin cells as a powerful model system for studying secretion, the authors study the regulatory role of complexin in secretion. Complexin is still enigmatic in its regulatory role, as it ...

Ph.D. position available for students with the following background: electrical with biomedical engineering emphasis, biomedical engineering, biology, neurobiology, biochemistry. Please send your CV, ...

However, long-term exposure of the heart to elevated norepinephrine and epinephrine levels, originating from sympathetic nerve endings and chromaffin cells of the adrenal gland, results in further ...

This analysis program can be used to detect and characterize amperometric spikes recorded from chromaffin cells, PC12 cells, neurons, etc. The following parameters can be calculated: Download the file ...
