Root aeration via aerenchymatous phellem: three-dimensional micro-imaging and radial O2 profiles in Melilotus siculus KU Leuven
• Internal root aeration enables waterlogging-tolerant species to grow in anoxic soil. Secondary aerenchyma, in the form of aerenchymatous phellem, is of importance to root aeration in some dicotyledonous species. Little is known about this type of aerenchyma in comparison with primary aerenchyma. • Micro-computed tomography was employed to visualize, in three dimensions, the microstructure of the aerenchymatous phellem in roots of Melilotus ...
A comprehensive dataset of image sequences covering 20 fluorescent protein labels and 12 imaging conditions for use in super-resolution imaging KU Leuven
Super-resolution fluorescence microscopy techniques allow imaging fluorescently labelled structures with a resolution that surpasses the diffraction limit of light (approx. 200nm). The quality and, thus, reliability of each of these techniques is strongly dependent on (1) the quality of the optics, (2) the fitness of the specific fluorescent label for the given technique and (3) the algorithms being used. Of these, the fitness of the labels is ...
Multi-parametric imaging of tumor spheroids with ultra-bright and tunable nanoparticle O-2 probes Ghent University
Minimizing the scatter contribution and spatial spread due to the absorption grating G2 in grating-based phase-contrast imaging KU Leuven
© 2018 SPIE. In previous research1 it was shown that in grating-based phase-contrast imaging (GB-PCI) for low scatter objects, G2 is the dominant scattering source. This scatter is manifested in a different way compared to object scatter, as scattered photons that remain local to the interaction site may even increase object contrast, but reduce system visibility. In this work the magnitude and the spatial distribution of scattered photons from ...
Histopathological correlations and fat replacement imaging patterns in recessive limb-girdle muscular dystrophy type 12 KU Leuven
BACKGROUND: Despite the widespread use of proton density fat fraction (PDFF) measurements with magnetic resonance imaging (MRI) to track disease progression in muscle disorders, it is still unclear how these findings relate to histopathological changes in muscle biopsies of patients with limb-girdle muscular dystrophy autosomal recessive type 12 (LGMDR12). Furthermore, although it is known that LGMDR12 leads to a selective muscle involvement ...
Interferometric imaging of the type IIIb and U radio bursts observed with LOFAR on 22 August 2017 KU Leuven
High-resolution in vivo imaging of xylem-transported CO2 in leaves based on real-time 11C-tracing Ghent University
Plant studies using the short-lived isotope C-11 to label photosynthate via atmospheric carbon dioxide (CO2), have greatly advanced our knowledge about the allocation of recent photosynthate from leaves to sinks. However, a second source for photosynthesis is CO2 in the transpiration stream, coming from respiration in plant tissues. Here, we use in vivo tracing of xylem-transported (CO2)-C-11 to increase our knowledge on whole plant carbon ...
