Imaging of pH in vivo using hyperpolarized 13C-labelled zymonic acid

Autor: Stephan Düwel, Christian Hundshammer, Malte Gersch, Benedikt Feuerecker, Katja Steiger, Achim Buck, Axel Walch, Axel Haase, Steffen J. Glaser, Markus Schwaiger, Franz Schilling

Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-9 (2017)

Local pH alterations can be manifestations of pathologies such as cancer, inflammation and ischaemia. Here Düwelet al. show hyperpolarized 13C-labelled zymonic acid can be used as a non-invasive probe to map and measure pH in vivo, suggesting it as

Hyperpolarized Amino Acid Derivatives as Multivalent Magnetic Resonance pH Sensor Molecules

Autor: Christian Hundshammer, Stephan Düwel, David Ruseckas, Geoffrey Topping, Piotr Dzien, Christoph Müller, Benedikt Feuerecker, Jan B. Hövener, Axel Haase, Markus Schwaiger, Steffen J. Glaser, Franz Schilling

Publikováno v: Sensors, Vol 18, Iss 2, p 600 (2018)

pH is a tightly regulated physiological parameter that is often altered in diseased states like cancer. The development of biosensors that can be used to non-invasively image pH with hyperpolarized (HP) magnetic resonance spectroscopic imaging has th

The head morphology of Ascioplaga mimeta (Coleoptera: Archostemata) and the phylogeny of Archostemata

Autor: Thomas HÖRNSCHEMEYER, Jürgen GOEBBELS, Gerd WEIDEMANN, Cornelius FABER, Axel HAASE

Publikováno v: European Journal of Entomology, Vol 103, Iss 2, Pp 409-423 (2006)

Internal and external features of the head of Ascioplaga mimeta (Coleoptera: Archostemata) were studied with micro X-ray computertomography (µCT) and nuclear magnetic resonance imaging (NMRI). These methods allowed the reconstruction of the entire i

Multisite Kinetic Modeling of 13C Metabolic MR Using [1-13C]Pyruvate

Autor: Pedro A. Gómez Damián, Jonathan I. Sperl, Martin A. Janich, Oleksandr Khegai, Florian Wiesinger, Steffen J. Glaser, Axel Haase, Markus Schwaiger, Rolf F. Schulte, Marion I. Menzel

Publikováno v: Radiology Research and Practice, Vol 2014 (2014)

Hyperpolarized 13C imaging allows real-time in vivo measurements of metabolite levels. Quantification of metabolite conversion between [1-13C]pyruvate and downstream metabolites [1-13C]alanine, [1-13C]lactate, and [13C]bicarbonate can be achieved thr

A Portable NMR Spectrometer With a Probe Head Combining RF and DC Capabilities to Generate Pulsed-Field Gradients

Autor: Christoph Staat, Alexandra Heidsieck, Axel Haase, Bernhard Gleich, Jonathan Rapp, Andreas Wegemann

Publikováno v: IEEE Transactions on Instrumentation and Measurement. 69:8628-8636

Portable nuclear magnetic resonance (NMR) spectrometers are used in various scientific fields. A vast number of applications are suitable for low-field permanent magnets. However, most of these systems lack the ability of pulsed-field gradients as th

Magnetic Resonance in Medicine

Purpose The linear change of the water proton resonance frequency shift (PRFS) with temperature is used to monitor temperature change based on the temporal difference of image phase. Here, the effect of motion-induced susceptibility artifacts on the
