Anti-adrenergic effects of endothelin on human atrial action potentials are potentially anti-arrhythmic [PDF]

open access: yes, 2006
Endothelin-1 (ET-1) is elevated in patients with atrial fibrillation (AF) and heart failure. We investigated effects of ET-1 on human atrial cellular electrophysiological measurements expected to influence the genesis and maintenance of AF.

Cannabinoids From Trema micranthum (L.) Blume (Cannabaceae): A Cannabinoid Profiling System

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Trema micranthum (L.) Blume is a species from the Cannabaceae botanical family, present all over the tropics. A recent study conducted by our group identified the presence of cannabidiol (CBD), Δ9‐tetrahydrocannabinol, cannabidiolic acid, and tetrahydrocannabinolic acid‐A in T. micranthum extracts.

Differential regulations of vestibulo-ocular reflex and optokinetic response by β- and α2-adrenergic receptors in the cerebellar flocculus

open access: yesScientific Reports, 2017
Norepinephrine modulates synaptic plasticity in various brain regions and is implicated in memory formation, consolidation and retrieval. The cerebellum is involved in motor learning, and adaptations of the vestibulo-ocular reflex (VOR) and optokinetic ...

Biosynthesis of Ephedrine Initiated by Pyridoxal Phosphate‐Dependent Formation of Cathinone

open access: yesChemBioChem, EarlyView.
An alternative pathway to ephedra alkaloids via (S)–cathinone is investigated in plants. This pathway circumvents the formation of 1‐phenylpropane‐1,2‐dione as an intermediate, which has been part of the predominantly postulated biosynthetic pathway for the last decades. This alternative pathway involves an enzymatic pyridoxal phosphate (PLP)‐dependent
