Stable isotope labeling and ultra-high-resolution NanoSIMS imaging reveal alpha-synuclein-induced changes in neuronal metabolism in vivo

Bernard Schneider, Graham Knott, Bohumil Maco, Anders Meibom, Stéphane Laurent Escrig, Sofia Carmen Suzanne Spataro, Louise Helene Soegaard Jensen

In Parkinson's disease, pathogenic factors such as the intraneuronal accumulation of the protein alpha-synuclein affect key metabolic processes. New approaches are required to understand how metabolic dysregulations cause degeneration of vulnerable subtype ...

Correlated cryo-SEM and CryoNanoSIMS imaging of biological tissue

Arnaud Comment, Cristina Martin Olmos, Tian Cheng, Anders Meibom, Stéphane Laurent Escrig, Florent Olivier Vivien Plane, Louise Helene Soegaard Jensen, Nils Rädecker

BackgroundThe development of nanoscale secondary ion mass spectrometry (NanoSIMS) has revolutionized the study of biological tissues by enabling, e.g., the visualization and quantification of metabolic processes at subcellular length scales. However, the a ...

Amoebocytes facilitate efficient carbon and nitrogen assimilation in the Cassiopea -Symbiodiniaceae symbiosis

Anders Meibom, Stéphane Laurent Escrig, Louise Helene Soegaard Jensen, Sandrine Denise Françoise Bessette, Niclas Heidelberg Lyndby, Nils Rädecker, Michael Kühl

The upside-down jellyfish Cassiopea engages in symbiosis with photosynthetic microalgae that facilitate uptake and recycling of inorganic nutrients. By con- trast to most other symbiotic cnidarians, algal endosymbionts in Cassiopea are not restricted to th ...

Noninvasive LHC transverse beam size measurement using inelastic beam-gas interactions

Aurelio Bay, Tatsuya Nakada, Guido Haefeli, Olivier Schneider, Frédéric Blanc, Axel Kuonen, Olivier Göran Girard, Massimo Giovannozzi, Zhirui Xu, Mark Tobin, Sebastiana Gianì, Louise Helene Soegaard Jensen, Plamen Hristov Hopchev

The beam-gas vertex (BGV) detector is an innovative instrument measuring noninvasively the transverse beam size in the Large Hadron Collider (LHC) using reconstructed tracks from beam-gas interactions. The BGV detector was installed in 2016 as part of the ...

Contaminant loading and competitive access of Pb, Zn and Mn(III) to vacancy sites in biogenic MnO2

Jasquelin Peña, Louise Helene Soegaard Jensen

The scavenging properties of MnO2 are largely attributed to sorption on layer vacancy sites. However, co-occurrence of Mn(II, III) with MnO2 can change mineral reactivity by modifying its Mn(III) content or number of free vacancy sites. These processes are ...

Oxidative stability and microstructure of 5% fish-oil-enriched granola bars added natural antioxidants derived from brown alga Fucus vesiculosus

Louise Helene Soegaard Jensen

The aims of this study were to (i) investigate the ability of Icelandic brown algae Fucus vesiculosus extracts to inhibit lipid oxidation in granola bars fortified with fish oil-in-water emulsion; (ii) investigate whether addition of the seaweed extracts a ...
