Electrochemical titrations and reaction time courses monitored in situ by magnetic circular dichroism spectroscopy [PDF]
, 2011 Magnetic circular dichroism (MCD) spectra, at ultraviolet–visible or near-infrared wavelengths (185–2000 nm), contain the same transitions observed in conventional absorbance spectroscopy, but their bisignate nature and more stringent selection rules ...

Diamine Oxidase Deficiency [PDF]
Deutsches Ärzteblatt international, 2012 In Box 5, which lists special diagnostic tests depending on the lead symptoms, I miss under the main symptom “diarrhea” any mention of diamine oxidase deficiency, which in my opinion is an important cause of histamine intolerance. Maintz, Bieber, and Novak described this in an issue of Deutsches Arzteblatt in 2006.

Action of Mepacrine on Diamine Oxidase [PDF]
Nature, 1945 THE observation by Hammick and Chambers1 that 2-chloro-5-amino-7-hydroxyacridine is a breakdown product of mepacrine found in human urine shows that the side-chain of mepacrine is removed by the scission of a C–N linkage.

Comparing hydrazine-derived reactive groups as inhibitors of quinone-dependent amine oxidases
Journal of Enzyme Inhibition and Medicinal Chemistry, 2017 Lysyl oxidase has emerged as an important enzyme in cancer metastasis. Its activity has been reported to become upregulated in several types of cancer, and blocking its activity has been shown to limit the metastatic potential of various cancers.

Portosystemic hepatic encephalopathy model shows reversal learning impairment and dysfunction of neural activity in the prefrontal cortex and regions involved in motivated behavior [PDF]
Journal of Clinical Neuroscience (2011)18(5):690-4, 2011 Hepatic encephalopathy is a neurological complication that affects attention and memory. Experimental animal models have been used to study hepatic Encephalopathy, the most frequent being the portacaval shunt. In order to determine learning impairment and brain functional alterations in this model, we assessed reversal learning and neural metabolic ...

Studies of Pig Kidney Diamine Oxidase. [PDF]
Acta Chemica Scandinavica, 1976 Preparations of pig kidney histaminase were analyzed for total compositions, N-terminal residues, patterns of tryptic peptides and for subunits under dissociating conditions. The crystalline enzyme is pure by several criteria but not completely homogeneous.
