Aβ42 promotes the aggregation of α‐synuclein splice isoforms via heterogeneous nucleation
FEBS Letters, EarlyView.The aggregation of amyloid‐β (Aβ) and α‐synuclein (αSyn) is associated with Alzheimer's and Parkinson's diseases. This study reveals that Aβ aggregates serve as potent nucleation sites for the aggregation of αSyn and its splice isoforms, shedding light on the intricate interplay between these two pathogenic proteins.

Observation of stable Néel skyrmions in cobalt/palladium multilayers with Lorentz transmission electron microscopy [PDF]
Nature Communications, 2017 Néel skyrmions are of high interest due to their potential applications in a variety of spintronic devices, currently accessible in ultrathin heavy metal/ferromagnetic bilayers and multilayers with a strong Dzyaloshinskii–Moriya interaction.

Molecular Oncology, EarlyView.Raphin‐1 reduces the survival of PED‐DHGG cells and enhances their radiation sensitivity through both PeIF2α‐dependent and PeIF2α‐independent mechanisms. Raphin‐1 sustains elevated levels of PeIF2α, contributing to its PeIF2α‐dependent effects. Additionally, raphin‐1 interacts with CReP to mediate a separate radiosensitizing pathway that operates ...

Oriented attachment explains cobalt ferrite nanoparticle growth in bioinspired syntheses
Beilstein Journal of Nanotechnology, 2014 Oriented attachment has created a great debate about the description of crystal growth throughout the last decade. This aggregation-based model has successfully described biomineralization processes as well as forms of inorganic crystal growth, which ...

Molecular Oncology, EarlyView.Small extracellular vesicles are a promising source of diagnostic molecules. We conducted a comprehensive study, including transcriptome profiling and RT‐qPCR validation on large cohorts of samples. Diagnostic panels enabling sensitive detection of colorectal cancer and precancerous lesions were established. Some molecules were differentially expressed

ELECTRON TRANSMISSION MICROSCOPY
Le Journal de Physique Colloques, 1974 The purpose of this short lecture is to explain why defects are imaged in the electron microscope, and to emphasize that a good understanding of the theory can lead to important informations about the defects. First, the different notions and parameters describing the diffraction of electrons by a perfect foil are introduced and discussed to some ...
