Open AccessAccelerated epigenetic aging and decreased natural killer cells based on DNA methylation in patients with untreated major depressive disorder
Major depressive disorder (MDD) is known to cause significant disability. Genome-wide DNA methylation (DNAm) profiles can be used to estimate biological aging and as epigenetic clocks. However, information on ...

Development of a compact dose verification system using a fluorescent screen for carbon-ion therapy
For quality assurance (QA) of therapeutic ion beams, a QA tool having high spatial resolution and quick verification is required. An imaging system with a fluorescent screen is suitable for the QA procedure. W...

Open AccessCarbon-ion scanning lung treatment planning with respiratory-gated phase-controlled rescanning: simulation study using 4-dimensional CT data
To moving lung tumors, we applied a respiratory-gated strategy to carbon-ion pencil beam scanning with multiple phase-controlled rescanning (PCR). In this simulation study, we quantitatively evaluated dose dis...

Characterization of thin-foil preformed plasmas for high-intensity laser plasma interactions
We observe the electron density distribution of preformed plasmas of a titanium foil target with the 400 nm probe beam as an interferometer. The preformed plasma at the front side of the target is generated by...
