This article aims to build up a simple, rapid and accurate capillary zone electrophoresis (CZE) method for the separation of biogenic amines (BAs). Here, 10 key BAs (phenethylamine, histamine, tryptamine, tyramine, 5-hydroxytryptamine, octopamine, dopamine, norepinephrine, epinephrine and carnosine)
Orthostatic intolerance (OI) or postural tachycardia syndrome (POTS) is a syndrome primarily affecting young females, and is characterized by lightheadedness, palpitations, fatigue, altered mentation, and syncope primarily occurring with upright posture and being relieved by lying down. There is
Norepinephrine (NE), a vital neurotransmitter in both the central and peripheral nervous systems, is synthesized by dopamine beta-hydroxylase (DBH) through the oxidation of dopamine (DA) to NE. DBH deficiency is a congenital disorder characterized by severe orthostatic hypotension, ptosis, and
BACKGROUND
Orthostatic intolerance is a syndrome characterized by lightheadedness, fatigue, altered mentation, and syncope and associated with postural tachycardia and plasma norepinephrine concentrations that are disproportionately high in relation to sympathetic outflow. We tested the hypothesis
Selegiline (deprenyl), a selective, irreversible inhibitor of monoamine oxidase type B (MAO-B) is widely used in the treatment of Parkinson's disease. As the first MAO-B inhibitor approved for the treatment of Parkinson's disease, concerns were raised about the safety of the drug based on the
Natural polysaccharides are extensively investigated as cell scaffold materials for cellular adhesion, proliferation, and differentiation due to their excellent biocompatibility, biodegradability, and biofunctions. However, their application is often severely limited by their mechanical behavior. In
