Mineral composition of Aegle marmelos (L.) corrêa ash: Exploration of its ability to mimic the function of different metalloenzymes

open access: yesChemistry of Inorganic Materials
The motivation to find functional models of different metalloenzymes comes from their potential to develop better catalysts inspired by nature. Generally, metalloenzymes can activate aerial dioxygen due to the metal ions in it.

MONOAMINE OXIDASE AND CATECHOL- O-METHYLTRANSFERASE INHIBITORS

open access: yesMedical Clinics of North America, 1999
Despite advances in the treatment of PD, there remain significant unmet therapeutic needs. This is particularly true at the later stages of the disease when dopaminergic therapy is complicated by motor fluctuations and dyskinesias. Inhibition of dopamine metabolism is a valuable adjunct to exogenous dopaminergic replacement.

Concentration of norepinephrine, serotonin, and histamine, and of amine-metabolizing enzymes in mammalian adipose tissue

open access: yesJournal of Lipid Research, 1963
The norepinephrine content of adipose tissue is shown to be very different in various animal species and different sites of origin, ranging from 0.03-1.4 μg/g. Adipose tissue also contains considerable amounts of serotonin (0.01-1.04 μg/g) and histamine (

CSF Monoamine Metabolites and Cognitive Trajectory in Early Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Imaging and postmortem studies indicate that abnormalities in monoaminergic neurotransmission contribute to cognitive impairment in Parkinson's disease (PD). However, it remains uncertain if cerebrospinal fluid (CSF) monoamine metabolites can serve as biomarkers of cognitive decline in early PD.

Boosting LPMO-driven lignocellulose degradation by polyphenol oxidase-activated lignin building blocks

open access: yesBiotechnology for Biofuels, 2017
Background Many fungi boost the deconstruction of lignocellulosic plant biomass via oxidation using lytic polysaccharide monooxygenases (LPMOs). The application of LPMOs is expected to contribute to ecologically friendly conversion of biomass into fuels ...
