Expanding the Tyrosine Kinase Domain of CSF1R? A Case Report From an Adult‐Onset Leukoencephalopathy
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Adult‐onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP), also termed hereditary diffuse leukoencephalopathy with spheroids‐1 (HDLS1), results from mutations in the CSF1R gene and leads to progressive leukoencephalopathy.

Proton therapy is a form of external beam radiotherapy that has several advantages over conventional photon (x-ray) radiotherapy. Protons are useful in 2 scenarios that apply to a large proportion of cancer patients: lack of exit dose allows for delivery of a therapeutic radiation dose to tumors in challenging anatomic locations, and reduction in ...

There are two facilities for clinical trials with protons in Japan: the National Institute of Radiological Sciences (NIRS), Chiba, and the Particle Radiation Medical Science Center (PARMS), University of Tsukuba. At the National Institute of Radiological Sciences, patient treatment with the 70 MeV proton beam began in November 1979, and 29 patients ...

A proton therapy system in Nagoya Proton Therapy Center
Australasian Physical & Engineering Sciences in Medicine, 2016The purpose of this paper is to describe an outline of a proton therapy system in Nagoya Proton Therapy Center (NPTC). The NPTC has a synchrotron with a linac injector and three treatment rooms: two rooms are equipped with a gantry and the other one is equipped with a fixed horizontal beamline.

Annual Review of Biophysics and Bioengineering, 1982
Conventional radiotherapy with high energy photons and electrons has been remarkably successful in treating many localized tumors. However, if tumors are large or are located very close to critical normal structures, it becomes very difficult to deliver a tumoricidal dose to the entire tumor volume without compromising the function of these adjacent ...

Simultaneous dose and dose rate optimization (SDDRO) for FLASH proton therapy.
Medical Physics (Lancaster), 2020PURPOSE FLASH radiotherapy (RT) can potentially reduce normal tissue toxicity while preserving tumoricidal effectiveness to improve the therapeutic ratio. The key of FLASH for sparing normal tissues is to irradiate tissues with an ultra-high dose rate (i.

The Cancer Journal, 2009
The technology that is used for the production and delivery of therapeutic proton beams is reviewed. Increased interest in this treatment modality has inspired a new generation of technology development and research into methods that will make proton treatment facilities more widely available (less expensive) and more efficient. Proton beam therapy has

Optimal Allocation of Proton Therapy Slots in Combined Proton-Photon Radiation Therapy
International Journal of Radiation Oncology*Biology*Physics, 2021Proton therapy is a limited resource that is not available to all patients who may benefit from it. We investigated combined proton-photon treatments, in which some fractions are delivered with protons and the remaining fractions with photons, as an approach to maximize the benefit of limited proton therapy resources at a population level.To quantify ...
