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

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

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

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

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, Nils Rädecker, Louise Helene Soegaard Jensen, Niclas Heidelberg Lyndby, Sandrine Denise Françoise Bessette, 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 ...

Combined deletion of Glut1 and Glut3 impairs lung adenocarcinoma growth

Rolf Gruetter, Anders Meibom, Graham Knott, Bernard Lanz, Stéphane Laurent Escrig, Nadine Fournier, Mario Gaetano Lepore, Etienne Meylan, Louise Helene Soegaard Jensen, Caroline Anne-Lyse Contat

Glucose utilization increases in tumors, a metabolic process that is observed clinically by F-18-fluorodeoxyglucose positron emission tomography (F-18-FDG-PET). However, is increased glucose uptake important for tumor cells, and which transporters are impl ...

Vibrio coralliilyticus infection triggers a behavioural response and perturbs nutritional exchange and tissue integrity in a symbiotic coral

Anders Meibom, Louise Helene Soegaard Jensen, Emma Mary Gibbin

Under homoeostatic conditions, the relationship between the coralPocillopora damicornisandVibrio coralliilyticusiscommensal. An increase in temperature, or in the abundance ofV. coralliilyticus, can turn this association pathogenic,causing tissue lysis, ex ...

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

Olivier Schneider, Aurelio Bay, Guido Haefeli, Frédéric Blanc, Tatsuya Nakada, Mark Tobin, Zhirui Xu, Sebastiana Gianì, Plamen Hristov Hopchev, Olivier Göran Girard

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

Louise Helene Soegaard Jensen, Jasquelin Peña

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 ...
