Structural and Functional Imaging of Pancreatic Islets using Optical Coherence Microscopy

Corinne Berclaz

In diabetes, pancreatic beta-cells play a key role. These cells are organized within structures called islets of Langerhans inside the pancreas and produce insulin. Insulin is one of the main hormones contributing to glucose homeostasis, which is the hallm ...

NanoSIMS analysis of an isotopically labelled organometallic ruthenium(II) drug to probe its distribution and state in vitro

Paul Joseph Dyson, Graham Knott, Mary-Claude Croisier-Coeytaux, Anders Meibom, Kai Johnsson, Stéphane Laurent Escrig

The in vitro inter-and intra-cellular distribution of an isotopically labelled ruthenium(II)-arene (RAPTA) anti-metastatic compound in human ovarian cancer cells was imaged using nano-scale secondary ion mass spectrometry (NanoSIMS). Ultra-high resolution ...

Combined Optical Coherence and Fluorescence Microscopy to assess dynamics and specificity of pancreatic beta-cell tracers

Theo Lasser, Anne Grapin-Botton, Arno Pino Bouwens, Christophe Pache, Daniel Pawel Szlag, Corinne Berclaz, Antonio Lopez

The identification of a beta-cell tracer is a major quest in diabetes research. However, since MRI, PET and SPECT cannot resolve individual islets, optical techniques are required to assess the specificity of these tracers. We propose to combine Optical Co ...

Energy-selective neutron imaging for morphological and phase analysis of iron-nickel meteorites

Steven Luc X Peetermans

We propose energy-selective neutron imaging as a new and non-destructive method to investigate rare metallic meteorites. It is based on attenuation of a neutron beam of limited spectral distribution in a sample depending on the elemental composition and cr ...

Definition of the radiation fields for the JET gamma-ray spectrometer diagnostics

Patrick Blanchard

The JET gamma-ray diagnostics system provides information on the behaviour of fast particles within the tokamak plasma. Information on the spatial distribution of the interacting fast particles is obtained from the gamma-ray cameras, while energy distribut ...

Measurement of Tc distribution in NbSn CICC

Pierluigi Bruzzone, Davide Uglietti, Ciro Calzolaio

Knowledge of the actual Nb3Sn filaments' thermal strain, epsilon(th), in a cable-in-conduit conductor (CICC) is essential to predict the CICC performance in operation starting from the strand scaling laws for the critical current density J(c)(B, T, epsilon ...

A Compact Probe for Beta+Emitting Radiotracer Detection in Suregery, Biopsy, and Medical Diagnostics based on Silicon Photomultipliers

Edoardo Charbon, Claudio Bruschini, Marco Matter, Christian Mester

We present a new probe for radiotracer detection in vivo. The device is based on silicon photomultipliers coupled with a scintillator and wirelessly compensated for supply voltage and temperature variations. The probe is positron sensitive. ...

A Handheld Probe for beta(+)-Emitting Radiotracer Detection in Surgery, Biopsy and Medical Diagnostics based on Silicon Photomultipliers

Edoardo Charbon, Claudio Bruschini, Christian Mester

We present a new, handheld probe for radiotracer detection in vivo and inside operating theatres, where PET scanners cannot be used for radioguided surgery. The device is based on scintillation detectors optically coupled to Silicon Photomultipliers (SiPMs ...

β-Molybdenum nitride: synthesis mechanism and catalytic response in the gas phase hydrogenation of p-chloronitrobenzene

Lioubov Kiwi, Fernando Cardenas Lizana

A temperature programmed treatment of MoO3 in flowing N-2 + H-2 has been employed to prepare beta-phase molybdenum nitride (beta-Mo2N) which has been used to promote, for the first time, the catalytic hydrogenation of p-chloronitrobenzene. The reduction/ni ...

JET (He-3)-D scenarios relying on RF heating: survey of selected recent experiments

Alessandro Marinoni

Recent JET experiments have been devoted to the study of (He-3)-D plasmas involving radio frequency (RF) heating. This paper starts by discussing the RF heating efficiency theoretically expected in such plasmas, covering both relevant aspects of wave and o ...
