Field-dependent NMR relaxometry for Food Science: Applications and perspectives

, 2021
Background Nuclear Magnetic Resonance (NMR) relaxometry is widely used for food products characterization. In order to exploit the full potential of the relaxation methods one can look at magnetic field dependence of spin-lattice relaxation.

MRI Methods to Visualize and Quantify Adipose Tissue in Health and Disease

Biomedicines, 2023
MRI is the modality of choice for a vast range of pathologies but also a sensitive probe into human physiology and tissue function. For this reason, several methodologies have been developed and continuously evolve in order to non-invasively monitor ...

Disorder‐Driven Fast Na+ Transport: From Crystalline to Amorphous Networks in the Mixed‐Anion NaTaOxCl6−2x Oxychlorides

Advanced Energy Materials, EarlyView.
Oxygen substitution in NaTaOxCl6‐2x drives structural evolution from isolated [TaCl6]– octahedra, through oxygen‐bridged [Ta2OCl10]2– dimers, toward extended trans‐[TaO2Cl4]3– chain‐like arrangements. At intermediate compositions, zero‐dimensional corner‐sharing motifs are proposed to create a flexible, disordered framework that peaks ionic ...

Synthetic MRI Neuroimaging Correlates of Frailty: Correlations Between Frailty Scales and Brain Structural Integrity

AGING MEDICINE, EarlyView.
Frailty was associated with decreased gray and white matter brain volumes in older adults. Synthetic MRI further revealed relaxometry alterations correlated with frailty severity across multiple clinical scales. ABSTRACT Objectives Frailty, a common condition in the elderly, is characterized by a decline in physiological reserves and an increased ...

Multimodal Quantitative MRI Reveals No Evidence for Tissue Pathology in Idiopathic Cervical Dystonia

Frontiers in Neurology, 2019
Background: While in symptomatic forms of dystonia cerebral pathology is by definition present, it is unclear so far whether disease is associated with microstructural cerebral changes in idiopathic dystonia.
