TL;DR: Ramipril, compared with amlodipine, retards renal disease progression in patients with hypertensive renal disease and proteinuria and may offer benefit to patients without proteinuria.
Journal ArticleDOI
The Chromogranin–Secretogranin Family
TL;DR: The members of the chromogranin–secretogran in family of peptide hormones, biogenic amines, and neurotransmitters are enclosed within vesicles in the neuroendocrine system and a variety of neurons.
Journal ArticleDOI
Secretion of chromogranin A by peptide-producing endocrine neoplasms.
TL;DR: The elevation of plasma chromogranin A in subjects with endocrine tumors suggests that their neoplasms co-release chromog Granin A along with the usual resident hormone of the tumor, that these neoplasm could be characterized as "chromogran inomas," and that measurement of plasma ChromogranIn A may be a useful diagnostic procedure in subjectsWith endocrine tumor groups, especially multiple endocrine neoplasia.
Journal ArticleDOI
Novel autocrine feedback control of catecholamine release. A discrete chromogranin a fragment is a noncompetitive nicotinic cholinergic antagonist.
Sushil K. Mahata,Daniel T. O'Connor,Manjula Mahata,Seung Hyun Yoo,Laurent Taupenot,Hongjiang Wu,B. M. Gill,R J Parmer +7 more
TL;DR: This small domain within chromogranin A may contribute to a novel, autocrine, homeostatic (negative-feedback) mechanism controlling catecholamine release from chromaffin cells and neurons.
Journal ArticleDOI
Plasma hydrogen peroxide production in hypertensives and normotensive subjects at genetic risk of hypertension.
TL;DR: Hydrogen peroxide is produced in blood plasma and elevation of its level could constitute a pathogenic factor in vascular organ damage attendant upon systemic hypertension.
