A combination of plasma DAO and citrulline levels as a potential marker for acute mesenteric ischemia [PDF]

open access: yesLibyan Journal of Medicine, 2013
Introduction: There is no valid and reliable diagnostic test for early diagnosis of acute mesenteric ischemia (AMI). The aim of this study was to measure the plasma levels of diamine oxidase (DAO) and citrulline in AMI to gain insight into its early ...

Diamine Oxidase in Rabbit Liver [PDF]

open access: yesEuropean Journal of Biochemistry, 1973
Subfractionation of the microsomes according to Dallner [4] showed that diamine oxidase is concentrated in the smooth microsomes.Centrifugation of the post‐mitochondrial supernatant treated with CsCl on a discontinuous three‐step gradient consisting of 0.8 M sucrose (density 1.12 g/ml) layered on 1.3 M sucrose (density 1.20 g/ml) resulted in three ...

Diazirines Beyond Photoaffinity Labeling: A Comprehensive Overview of Applications in Biological Sciences, Materials Chemistry, and NMR‐Spectroscopy

open access: yesAngewandte Chemie, Volume 138, Issue 4, 22 January 2026.
Diazirines are three‐membered, nitrogen‐containing heterocycles that decompose under light or heat to generate carbenes. For the past two decades, they have served mainly as minimally invasive tags in photoaffinity labeling (PAL). More recently, their value as versatile carbene precursors has been recognized.

Electrochemical titrations and reaction time courses monitored in situ by magnetic circular dichroism spectroscopy [PDF]

open access: yes, 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 ...

Comparing hydrazine-derived reactive groups as inhibitors of quinone-dependent amine oxidases

open access: yesJournal 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.

A Model for the Development of the Rhizobial and Arbuscular Mycorrhizal Symbioses in Legumes and Its Use to Understand the Roles of Ethylene in the Establishment of these two Symbioses [PDF]

open access: yes, 2002
We propose a model depicting the development of nodulation and arbuscular mycorrhizae. Both processes are dissected into many steps, using Pisum sativum L. nodulation mutants as a guideline. For nodulation, we distinguish two main developmental programs,

Stimulation of antioxidative enzymes and polyamines during stripe rust disease of wheat

open access: yesBiologia Plantarum, 2010
Content of polyamines and activities of antioxidative enzymes in response to stripe rust disease caused by Puccinia striiformis have been studied in two wheat (Triticum aestivum L.) cultivars PBW 343 (resistant) and HD 2329 (susceptible).

Inhibiting Copper Amine Oxidase Using L-Aminoguanidine Induces Cultivar and Age-Dependent Alterations of Polyamine Catabolism in Tomato Seedlings

open access: yesAgriculture, 2022
Many effects of polyamines (PAs) are well known in plant developmental processes; however, the significance of their catabolism is not well understood. Copper amine oxidase (CuAO) is involved in the degradation of diamine putrescine (Put).
