Combined carbon ion radiotherapy and immunotherapy: leveraging the immunological advantages of carbon ion

Frontiers in Immunology
Immunotherapy represents a systemic approach to cancer treatment; however, its effectiveness can be limited by intrinsic tumor resistance or immunosuppressive mechanisms within the tumor microenvironment. In contrast, carbon ion radiotherapy (CIRT) demonstrates considerable immunomodulatory potential owing to its distinct biological properties.

Recent Innovations in Carbon-Ion Radiotherapy [PDF]

Journal of Radiation Research, 2010
In the last few years, hospital-based facilities for carbon-ion radiotherapy are being constructed and proposed in Europe and Asia. During the next few years, several new facilities will be opened for carbon-ion radiotherapy in the world. These facilities in operation or under construction are categorized in two types by the beam shaping method used ...

AscF in the mycobacterial CIII–CIV supercomplex lacks metal and nucleotide binding but links malate oxidation to respiration

FEBS Letters, EarlyView.
The mycobacterial CIII‐CIV respiratory supercomplex is an obligate assembly, encompassing several subunits of unknown functions. We have characterized the intracellular subunit AscF, and show that it is unlikely to be a sensor for metals or nucleotides, but is required for growth on nonfermentable energy sources, and likely works as an adapter for ...

Separation and hydrogenation of nitrate ions by micro-scale capacitive-faradaic fuel cells (CFFCs)

Electrochemistry Communications, 2020
A new electrochemical process is proposed for a zero-discharge removal of nitrate ions from water. The process utilizes micro-scale capacitive-faradaic fuel cells (CFFC) made of activated carbon particles loaded with a Pt-Cu catalyst capable of oxygen ...

Disposable electrochemical sensor for the detection of lead(II) ions in the natural water

International Journal of Electrochemical Science, 2021
The leaching of metal ions from the mines may result in pollution of the surrounding waters. In this work, we propose a composite material that combines porous carbon and graphene (G-C), which shows a very high sensitivity to lead ions.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Mini-TEPC Microdosimetric Study of Carbon Ion Therapeutic Beams at CNAO

EPJ Web of Conferences, 2017
Mono-energetic carbon ion scanning beams of 195.2 MeV/u at the Italian National Centre for Oncological Hadrontherapy (CNAO) have been used to study the microdosimetric features of an “active” carbon ion beam used in hadrontherapy.

Fission of Uranium-238 with Carbon Ions [PDF]

Physical Review, 1961
Angular distributions and kinetic-energy spectra of fragments, and cross sections for fission of U/sup 238/ with 63- to 124-Mev C/sup 12/ ions, were measured with the use of a silicon p-n junction detector. The distributions were analyzed in terms of the formation of a compound nucleus and subsequent decay by evaporation of neutrons in competition with
