Emerging experimental and computational methods for studying redox‐regulated structural transitions

FEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Untersuchung der radialen Ionisationsdichteverteilung von schweren Ionen mit einer optischen Teilchenspurkammer und mit Monte-Carlo-Simulationen [PDF]

, 2007
In the present work we applied the Optically read out PArticle track Chamber, OPAC, for the measurement of radial dose distributions, d(r), around tracks of heavy ions passing through the gas-filled sensitive volume of the chamber. The measured data were

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Scanning force microscopy on heavy-ion tracks in muscovite mica: track diameter versus energy loss and loading force

, 1997
Mica is very sensitive to heavy-ion irradiation and offers an ideal surface for scanning force microscopy (SFM) of ion-induced tracks. In our work, mica samples are irradiated with heavy ions (the kinetic energies ranging from 0.5 to 2.76 GeV) at the ...

Modification of Fe-B based metallic glasses using swift heavy ions

EPJ Web of Conferences, 2012
We report on small-angle x-ray scattering (SAXS) measurements of amorphous Fe80B20, Fe85B15, Fe81B13.5Si3.5C2, and Fe40Ni40B20 metallic alloys irradiated with 11.1 MeV/u 132Xe, 152Sm, 197Au, and 8.2 MeV/u 238U ions.

Extracellular vesicle lipidomics liquid biopsy reveals systemic and tumor microenvironment metabolic reprogramming in ovarian cancer

Molecular Oncology, EarlyView.
Extracellular vesicle (EV) lipidomic profiling of plasma and ascites from patients with high‐grade serous ovarian cancer and of ovarian cancer cell lines reveals enrichment of triglycerides (TGs), diacylglycerols (DGs), phosphatidylcholine (PCs), sphingomyelins (SMs), reflecting tumor metabolic reprogramming.

Track constrained RTK for railway applications1

, 2016
At the start of missions trains compliant with the European ERTMS/ETCS standard have to run in Staff Responsible Mode (SRM) until the track where the train is lying on is identified by the Control Center (i.e., the Radio Block Center).

Nanostructures evolution assessment and spectroscopic properties modification induced by electronic energy loss in KTaO3 crystal

Materials & Design, 2022
Modifications of micro/nanostructure and photoelectric properties under swift ion irradiation (645 MeV Xe35+) of KTaO3 crystal with varying electronic energy losses (7.2–31.4 keV/nm) and ion velocities (0.18–5.00 MeV/u) have been studied by combining ...

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Comprehensive Understanding of Hillocks and Ion Tracks in Ceramics Irradiated with Swift Heavy Ions

Quantum Beam Science, 2020
Amorphizable ceramics (LiNbO3, ZrSiO4, and Gd3Ga5O12) were irradiated with 200 MeV Au ions at an oblique incidence angle, and the as-irradiated samples were observed by transmission electron microscopy (TEM).
