Summary: Computed tomography (CT) is an important clinical diagnostics method, but its current limit to X-rays' attenuation contrast only can be expanded with dark-field imaging. Dark-field imaging offers access to more tissue properties, such as micro-structural texture or porosity. However, up-scaling this method to clinical scale is complex due to design constraints such as limited manufacturing technology and minimal modifications to the CT gantry. In this study, the advantages of an inverse interferometer and a triangular grating profile are discussed, making a compact and sensitive interferometer implementation feasible. The evaluation of the triangular grating profile reveals a deviation in the interference pattern compared to standard grating profiles, which must be taken into consideration in subsequent data processing.

Summary: This study used cutting-edge techniques to explore the morphology of flax stems and fibers and found that various extracted fibers contained significant amounts of kink-bands. However, no kink-bands were observed at the scale of green or retted stems. This suggests that the stress experienced by plants during their growth is not enough to generate these structural defects, and they are only revealed after mechanical extraction of the fibers.

Summary: Propagation-based phase contrast imaging with a laboratory x-ray source is useful for studying samples with low absorption contrast. Recent advances in X-ray lab sources allow for higher magnification and shorter source-sample distance, resulting in enhanced edge contrast. The optimal magnification for edge enhancement fringes depends on source size, sample feature steepness, and detector resolution. A stronger influence of sample feature on optimal magnification is observed in this high-magnification geometry.

Summary: Nephrotoxicity is an important factor to be assessed during drug discovery and development, and in vitro cell-based assays are commonly used for this purpose. However, translating the results of these assays to vertebrates, including humans, is challenging. In this study, we evaluated whether zebrafish larvae could serve as a screening model for detecting gentamicin-induced changes in the kidney. We compared the results of the zebrafish larvae with kidney biopsies from gentamicin-treated mice to validate the model.

Summary: Synchrotron X-ray phase-contrast tomography (XPCT) can visualize amyloid-beta (A beta) plaques from Alzheimer's Disease (AD) in label-free brain samples. This study suggests that the contrast of A beta in XPCT may be caused by A beta fibrils and/or metals trapped in the plaques. Analysis of brain samples from different types of AD patients and AD models reveals that a hyperdense contrast formation of A beta plaques in XPCT images is associated with biometal entrapment within plaques.

Summary: Expansion of extracellular matrix, specifically aggrecan, occurs in all stages of pulmonary angiopathy associated with pulmonary arterial hypertension (PAH). Aggrecan accumulates in the pulmonary arteries of PAH patients and is localized to cellular lesions rather than fibrotic or collagenous lesions. The upregulation of the potential aggrecanase ADAMTS15 in PAH suggests dysregulation of aggrecan turnover is a response to altered hemodynamics. These findings support the potential therapeutic targeting of aggrecan and aggrecanase regulation in PAH.

Summary: This study conducted an extensive multi-scale statistical analysis on flax fibres extracted from different batches processed with varying scutching and combing conditions. It found that the occurrence of kink-bands in the fibres is related to their mechanical properties, with uncombed fibres having more cortical residues and larger surface kink-bands. The results show that changes in kink-bands structure are responsible for the evolutions in mechanical behavior.
