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

open access: yesFrontiers 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.

Ion Beam Analyses of Carbon Nanotubes [PDF]

open access: yesThe Journal of Physical Chemistry B, 2005
The utility of ion beam analysis (IBA) techniques to quantitatively determine impurities in carbon nanotubes (CNTs) over a wide range of atomic numbers is demonstrated. Such techniques have not previously been used to monitor impurities and their effects in this unique material. Despite the difficulty in mounting the samples (which generally are formed

Boundary layer chemical vapor synthesis of self-organized radial filled-carbon-nanotube structures [PDF]

open access: yes, 2013
We report a new chemical vapor synthesis method that exploits random fluctuations in the viscous boundary layer between a laminar vapor flow and a surface to yield a not previously observed product: radial ferromagnetically filled-carbon-nanotube ...

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

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

open access: yesElectrochemistry 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 ...

Recent Innovations in Carbon-Ion Radiotherapy [PDF]

open access: yesJournal 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 ...

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

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

open access: yesEPJ 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.

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

open access: yesMolecular 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 ...
