Statin usage, vascular diagnosis and vascular risk factors in Parkinson's disease [PDF]

open access: yes, 2017
Background and aims: Vascular disease is a common comorbidity in Parkinson’s disease patients. Statins are potentially neuroprotective for Parkinson’s disease through non-vascular mechanisms.

Highly Sensitive Electrochemical Biosensor Based on Hairy Particles with Controllable High Enzyme Loading and Activity

open access: yesAdvanced Functional Materials, EarlyView.
For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,

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 (

High-valent copper in biomimetic and biological oxidations [PDF]

open access: yes, 2016
A long-standing debate in the Cu-O2 field has revolved around the relevance of the Cu(III) oxidation state in biological redox processes. The proposal of Cu(III) in biology is generally challenged as no spectroscopic or structural evidence exists ...

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 ...
