TLDR
The LC-MS/MS method is sufficiently simple and reliable enough to replace the currently used HPLC method with fluorescence detection in which putrescine is not always detectable.About:

Health effects and occurrence of dietary polyamines: a review for the period 2005-mid 2013.
TL;DR: The data on the polyamine contents in raw food materials increased considerably during the reviewed period, while information on their changes during processing and storage have yet to be fragmentary and inconsistent.

TL;DR: Results indicate that putrescine is a pathogen-produced virulence metabolite that accelerates disease indirectly by affecting host physiology by manipulating its host to increase nutrients in tomato xylem sap.
Journal ArticleDOI
Quantitation of cellular metabolic fluxes of methionine.
TL;DR: The method enables the quantification of flux through the pro-tumorigenic enzyme ornithine decarboxylase, and this flux increases 2-fold following MTAP deletion, and the analytical approach used to quantify methionine metabolic fluxes is applicable for other metabolic systems affected by mixing of intracellular and extracellular metabolite pools.

The identification and quantification of biogenic amines in Korean turbid rice wine, Makgeolli by HPLC with mass spectrometry detection
TL;DR: In this article, a rapid and reliable method for the simultaneous determination of 9 biogenic amines (BAs; agmatine, phenylethylamine, tyramine, putrescine, cadaverine, histamine, tryptamine, spermidine, and spermine) in Korean turbid rice wine, Makgeolli, was optimized and validated using ultra-high pressure liquid chromatography-electrospray tandem mass spectrometry (UHPLC-ESI-MS/MS).
Journal ArticleDOI
Arbuscular Mycorrhizal Fungi Regulate Polyamine Homeostasis in Roots of Trifoliate Orange for Improved Adaptation to Soil Moisture Deficit Stress.
TL;DR: In this paper, the authors investigated the effect of AMF inoculation on polyamines, precursors, activities of PA synthases and degrading enzymes, and concentration of reactive oxygen species in the roots of trifoliate orange (Poncirus trifoliata) subjected to 15 days of soil moisture deficit stress (SMDS).

TL;DR: The overall process was successfully applied to identify and quantify biogenic amines in white-, red- and Retsina Greek wines and Greek beers, after treatment with polyvinylpyrrolidone.

High performance liquid chromatography/tandem mass spectrometry determination of biogenic amines in typical Piedmont cheeses.
TL;DR: The whole methodology, comprehensive of the homogenization-extraction process and HPLC-MS/MS analysis, has been applied in the analysis of three typical Piedmont (North-West Italy) cheeses, known as Toma Piemontese, Raschera and Castelmagno.
Journal ArticleDOI
Increased uptake of putrescine in the rhizosphere inhibits competitive root colonization by Pseudomonas fluorescens strain WCS365.
TL;DR: It is shown that putrescine is an important tomato root exudate component and that root-colonizing pseudomonads must carefully regulate their rate of uptake because increased uptake causes a decreased growth rate and, therefore, a decreased competitive colonization ability.

Polyamine contents in current foods: a basis for polyamine reduced diet and a study of its long term observance and tolerance in prostate carcinoma patients
TL;DR: A PRD associated with intermittent PIITD is a safe and well observed nutritional regimen and long term observance is possible, and performance status and pain scores were relatively stable during the trial.
