The renin–angiotensin system is an important component of the cardiovascular system.
Mounting evidence suggests that the metabolic products of angiotensin I and II—initially …

The renin-angiotensin system (RAS) constitutes a key hormonal system in the physiological
regulation of blood pressure through peripheral and central mechanisms. Indeed …

Peptides and proteins have been utilized as therapeutic agents for over 40 years. Traditional
approaches to quantify these molecules in biological matrices have utilized immunoassay …

Neuropeptides are short peptides in the range of 3–40 residues that are secreted for cell-cell
communication in neuroendocrine systems. In the nervous system, neuropeptides comprise …

To better understand the tissue distribution and activity of enzymes involved in angiotensin II
(Ang II) processing, we developed a novel molecular imaging method using matrix-assisted …

The renin-angiotensin system (RAS) of the brain produces a series of biologically active
angiotensinogen-derived peptides involved in physiological homeostasis and …

In recent years, the biological sciences have seen a surge in the development of methods,
including high-throughput global methods, for the quantitative measurement of biomolecule …

Here we demonstrate for the first time that by physically adsorbing aptamer onto conductive
film assembled via alternate adsorption of graphene/polyelectrolyte and methylene …

Vascular injury, characterized by endothelial dysfunction, inflammation, structural
remodeling, thrombosis and calcification leads to cardiovascular diseases. Angiotensin …

Neuropeptides regulate intercellular signaling as neurotransmitters of the central and
peripheral nervous systems, and as peptide hormones in the endocrine system. Diverse …
