introduction today, there is a growing interest in the use of hadrontherapy as an advanced radiotherapy technique. hadrontherapy is considered a promising tool for cancer treatment, given its high radiobiological effectiveness and high accuracy of dose deposition due to the physical properties of hadrons. however, new radiation modalities of dose delivery and on-line beam monitoring play crucia...

Boron neutron capture therapy (BNCT) is a radiotherapy that has mainly been used to treat malignant brain tumours, melanomas, and head and neck cancer. In BNCT, the patient receives an intravenous infusion of a B carrier, which accumulates in the tumour area. The tumour is irradiated with epithermal or thermal neutrons, which result in a boron neutron capture reaction B(n,α)Li. This generates h...

New and exciting developments in boron research in the past few years greatly contributed to better understanding of the role of boron in plants. Purification and identification of the first boron-polyol transport molecules resolved much of the controversy about boron phloem mobility. Isolation and characterization of the boron-polysaccharide complex from cell walls provided the first direct ev...

background: in radiation treatment of moving targets located in thorax region of patient body, the delivered dose does not match with the planned treatment, resulting in some over and under dosage in the tumor volume, as a function of motion magnitude and frequency. several efforts have been done to investigate the target motion effects on dose distribution in the target and surrounding normal ...

Abstract The calculation of fusion reactivity involves a complex six-dimensional integral that takes into account the cross section and velocity distributions two reactants. However, more simplified one-dimensional form can be useful in certain cases, such as for studying yield or diagnosing ion energy spectra. This simpler has been derived few special combination Maxwellian distributions, beam...

The purpose of this study is to synthesize new boron containing carrier compound for Boron Neutron Capture Therapy (BNCT) which two-component radiation therapy method that especially promising the treatment brain tumors and being actively researched in many countries. For research hyperbranched polyester (HBP), bifunctional p-carborane carborane-functionalized HBP were synthesized. Dipentaeryth...
