TLDR
The feasibility of HR 1H NMR spectroscopy based on intermolecular multiple-quantum coherence (iMQC) technique is explored and it provides an alternative for the investigation in cases with field distortions and with samples unsuitable for spinning.

On the use of ultracentrifugal devices for routine sample preparation in biomolecular magic-angle-spinning NMR.

TL;DR: Here it is argued for a more widespread adoption of how custom-made (or commercially available) ultracentrifugal devices can facilitate a simple, fast and reliable sample preparation process for routine MAS NMR sample preparation.
Journal ArticleDOI

Complete protocol for slow-spinning high-resolution magic-angle spinning NMR analysis of fragile tissues.

TL;DR: The performance of the slow HR-MAS NMR procedure is demonstrated on conventional and very delicate samples, for which the slow-spinning conditions are shown to preserve the structural integrity and to minimize intercompartmental leaks of metabolites.

NMR assignment of the in vivo daphnia magna metabolome.

TL;DR: This work represents the first time a comprehensive metabolic assignment of any small living organism has been performed using high field flow-based NMR and transfers are transferred back to line narrowed susceptibility suppressed 1H 1D NMR spectra to permit the maximum amount of information to be gained in the future without the need for 13C enrichment.

Measurement of Lipid Accumulation in Chlorella vulgaris via Flow Cytometry and Liquid-State ¹H NMR Spectroscopy for Development of an NMR-Traceable Flow Cytometry Protocol

TL;DR: Calibration of flow cytometric protocols using direct in situ measurement of TAG content via NMR will facilitate rapid development of more precise flow cytometry protocols, enabling investigation of algal lipid accumulation forDevelopment of more productive algal biofuel feedstocks and cultivation protocols.

Principles of nuclear magnetic resonance in one and two dimensions

TL;DR: In this paper, the dynamics of nuclear spin systems were studied by two-dimensional exchange spectroscopy and nuclear magnetic resonance imaging (NEMI) imaging, and two different correlation methods based on coherence transfer were proposed.

NMR and pattern recognition studies on liver extracts and intact livers from rats treated with α-naphthylisothiocyanate

TL;DR: The 1H MAS-NMR-PCA analysis allowed direct detection of all of the ANIT-induced tissue perturbations revealed by 1H NMR of extracts, enabling metabolic characterisation of the lesion, which included steatosis, bile duct obstruction and altered glucose/glycogen metabolism.

Salmon Quality: Methods to Determine the Quality Parameters

TL;DR: The objective of this paper is to review the important quality parameters, standards, and simple tools or methods to determine the quality of fresh Atlantic salmon (Saltno salar) based on a literature review and interviews conducted in several companies throughout Europe.

High-resolution NMR spectra in inhomogeneous fields via IDEAL (intermolecular dipolar-interaction enhanced all lines) method.

TL;DR: Intermolecular double-quantum technique is used to yield high-resolution NMR spectra in inhomogeneous magnetic fields and parameters are consistent with those extracted from one-dimensional spectra obtained in a homogeneous field.
