Measuring changes in substrate utilization in the myocardium in response to fasting using hyperpolarized [1-(13)C]butyrate and [1-(13)C]pyruvate

Arnaud Comment, Josefina Adriana Maria Bastiaansen

Cardiac dysfunction is often associated with a shift in substrate preference for ATP production. Hyperpolarized (HP) (13)C magnetic resonance spectroscopy (MRS) has the unique ability to detect real-time metabolic changes in vivo due to its high sensitivit ...

Protein acetylation in metabolism - metabolites and cofactors

Johan Auwerx, Elena Katsyuba, Hongbo Zhang, Keir Joe Menzies

Reversible acetylation was initially described as an epigenetic mechanism regulating DNA accessibility. Since then, this process has emerged as a controller of histone and nonhistone acetylation that integrates key physiological processes such as metabolis ...

Enantioselective Synthesis of Homoallylic Azides and Nitriles via Palladium-Catalyzed Decarboxylative Allylation

Jérôme Waser, Paola Caramenti, Maria Victoria Vita

Azides and nitriles are important building blocks for the synthesis of nitrogen-containing bioactive compounds. The first example of enantioselective palladiumcatalyzed decarboxylative allylation of alpha-azido and cyano beta-ketoesters is reported. Indano ...

Multiscattering-enhanced optical biosensor: multiplexed, non-invasive and continuous measurements of cellular processes

Olivier Martin, Christian Santschi, Volodymyr Koman

The continuous measurement of uptake or release of biomarkers provides invaluable information for understanding and monitoring the metabolism of cells. In this work, a multiscattering-enhanced optical biosensor for the multiplexed, non-invasive, and contin ...

Hyperpolarized 13C lactate as a substrate for in vivo metabolic studies in skeletal muscle

Rolf Gruetter, Arnaud Comment, Josefina Adriana Maria Bastiaansen, Hikari Ananda Infinity Yoshihara, Yuhei Takado

Resting skeletal muscle has a preference for the oxidation of lipids compared to carbohydrates and a shift towards carbohydrate oxidation is observed with increasing exercise. Lactate is not only an end product in skeletal muscle but also an important meta ...

Resistance to Diet-Induced Obesity and Associated Metabolic Perturbations in Haploinsufficient Monocarboxylate Transporter 1 Mice

Pierre Magistretti, Sylvain Eric Lengacher, Luc Pellerin

The monocarboxylate transporter 1 (MCT1 or SLC16A1) is a carrier of short-chain fatty acids, ketone bodies, and lactate in several tissues. Genetically modified C57BL/6J mice were produced by targeted disruption of the mct1 gene in order to understand the ...

In vivo metabolic studies in skeletal and cardiac muscle using ¹³C magnetic resonance spectroscopy

Josefina Adriana Maria Bastiaansen

Cardiac and skeletal muscle function relies on a continuous energy production via fatty acid metabolism and mitochondrial oxidation of pyruvate, with a fine balance between substrate delivery and utilization. Changes in metabolism are increasingly being im ...

In vivo detection of brain Krebs cycle intermediate by hyperpolarized magnetic resonance

Rolf Gruetter, Mor-Miri Mishkovsky, Arnaud Comment

The Krebs (or tricarboxylic acid (TCA)) cycle has a central role in the regulation of brain energy regulation and metabolism, yet brain TCA cycle intermediates have never been directly detected in vivo. This study reports the first direct in vivo observati ...

Nonlinear phase contrast enhancement

Demetri Psaltis, Alexandre Goy

We demonstrate a simple method to detect small phase steps using propagation in Kerr media. In experiments, nonlinear diffraction in acetone produced high contrast signals for a pi/80 phase mask. (C) 2010 Optical Society of America ...
