Analysis of Cancer Metabolism by Imaging Hyperpolarized Nuclei: Prospects for Translation to Clinical Research

Arnaud Comment

A major challenge in cancer biology is to monitor and understand cancer metabolism in vivo with the goal of improved diagnosis and perhaps therapy. Because of the complexity of biochemical pathways, tracer methods are required for detecting specific enzyme ...

Millimeter waves for NMR enhancement

Stefano Alberti, Jean-Philippe Ansermet, Giovanni Boero, Emile Jacques de Rijk, Alessandro Macor

By shining millimeter waves upon a sample, Dynamic Nuclear Polarization (DNP) provides a way to enhance Nuclear Magnetic Resonance (NMR) signals. Here we report on our efforts to realize a tunable gyrotron at 263.5 GHz and design consideration for coupling ...

Search for nuclear magnetic resonance evidence of spin accumulation

Aurore Rudolf

Developments towards an understanding of the nature of conductance at the interface between two different metallic layers – ferromagnetic and non magnetic – as well as the discovery of giant magnetoresistance have stirred attention from both the scientific ...

Improved ¹H-[¹³C] and ¹H NMR methods for in vivo measurement of cerebral metabolism

Lijing Xin

Nuclear magnetic resonance (NMR) spectroscopy can be applied in vivo to measure static or dynamic biochemical information, e.g., concentrations of metabolites and metabolic fluxes, using various nuclei such as 1H, 13C, 31P and 15N. The work of this thesis ...

In vivo magnetic resonance studies of glycogen and hyperpolarized lithium in the rat brain

Ruud van Heeswijk

Nuclear magnetic resonance (NMR) is used for a large array of applications, ranging from chemical characterization to oil drilling to medical imaging. In these fields NMR is used as an investigational tool, but new techniques and applications are continuou ...

Characterizing Slight Structural Disorder in Solids by Combined Solid-State NMR and First Principles Calculations

David Lyndon Emsley

A general approach for structural interpretation of local disorder in partially ordered solids is proposed, combining high-resolution two-dimensional (2D) nuclear magnetic resonance (NMR) and first principles calculations. We show that small chemical shift ...

Singlet-state exchange NMR spectroscopy for the study of very slow dynamic processes

Geoffrey Bodenhausen, Paul Romeo Vasos, Riddhiman Sarkar

Solution-state nuclear magnetic resonance method for singlet-state nuclear magnetic resonance-spectroscopy, involves performing transformation of zero-quantum coherences into singlet-state populations by radio frequency irradiation ...

2009

Nuclear magnetic relaxation in the presence of paramagnetic centres has gained increasing interest in recent years partly due to its importance for contrast agents in magnetic resonance imaging. Rational design of new more efficient agents is possible as a ...
