Valutazione della stabilità dell'ollio d'oliva vergine in conservazione mediante profilo 1H-NMR e chemiometria
(Servizi Editoriali Assoc Srl, 2021-10)
La qualità dell'ollio vergine di oliva (VOO) è correlata alla sue proprietà sensoriali e nutrizionali, alla stabilità ossidativa e alla sua conservazione. L'ossidazione del VOO porta alla formazione di sostanze sgradevoli, ...
Exotic litter of the invasive plant Ligustrum lucidum alters enzymatic production and lignin degradation by selected saprotrophic fungi
(National Research Council Canada-NRC Research Press, 2018-03)
Chemical changes in leaf input to forest soils have been reported to affect decay processes. In this work, litter mass loss and decomposition constants (k) during 200 days in solid-state fermentation of the native tree ...
Crop metabolomics: from diagnostics to assisted breeding
(Springer, 2018-11)
Background: Until recently, plant metabolomics have provided a deep understanding on the metabolic regulation in individual plants as experimental units. The application of these techniques to agricultural systems subjected ...
Magnetic resonance imaging of 1H long lived states derived from parahydrogen induced polarization in a clinical system
(Academic Press Inc Elsevier Science, 2016-01)
Hyperpolarization is a powerful tool to overcome the low sensitivity of nuclear magnetic resonance (NMR). However, applications are limited due to the short lifetime of this non equilibrium spin state caused by relaxation ...

(TAYLOR & FRANCIS LTD, 2016)
A model to describe the inhomogeneous broadening of NQR lines in chlorohalobenzenes with orientational or substitutional disorder
(Academic Press Inc Elsevier Science, 2017-10)
A simple model to explain the NQR lineshape in solids with orientational disorder or substitutional disorder is presented. The particular case of m-chlorobromobenzene is studied. It is based on the assumption that Bromine ...
Ejecución de un sistema piloto de tele-radiología en Medellín, Colombia
(Corporacion Editora Medica del Valle, 2006-01-01)
Objective: To implement a teleradiology pilot system in Medellín city using software for remote access, this allows the communication and interpretation of biomedical images at distance. Materials and methods: Images from ...
Noninvasive quantitative imaging of selective microstructure sizes via magnetic resonance
(American Physical Society, 2021-01)
Extracting quantitative microstructure information of living tissue by noninvasive imaging is an outstanding challenge for understanding disease mechanisms and allowing early stage diagnosis of pathologies. Magnetic resonance ...
Soyuretox, an intrinsically disordered polypeptide derived from soybean (Glycine max) ubiquitous urease with potential use as a biopesticide
(MDPI AG, 2019-11)
Ureases from different biological sources display non-ureolytic properties that contribute to plant defense, in addition to their classical enzymatic urea hydrolysis. Antifungal and entomotoxic effects were demonstrated ...
