Boron neutron capture therapy (BNCT) is one of the best treatment modalities for glioblastoma multiform that could selectively kill the tumor cells. To be successful in BNCT, it is crucial to have enough B in the tumor. l-boron phenylalanine (l-BPA) targeted thermo-responsive core-shell nanoparticles (NPs) of chitosan-poly(N-isopropylacrylamide) (PNIPAAm) were our idea for endocytosis via sialic acid receptors, and selective delivery of B to glial cells.

In this study, novel efficient pH-responsive boron phenylalanine (BPA) targeted nanoparticles (NPs) based on ionic liquid modified chitosan have been introduced for selective mitoxantrone (MTO) delivery to the U87MG glioma cells. Urocanic acid (UA) and imidazolium (Im) based ionic liquids were used for structural modification simultaneously.

Three high-LET alpha particles with an average energy of 4 MeV are generated at the point of interaction between proton and boron-11. Nevertheless, the cross-section of p+B11→3α interaction is negligible and dose increasement is unlikely.

Aims: The main objective of the present research is to analyze the caregiver effective dose during I-131 therapy of thyroid in some different situations using MCNP4C Monte Carlo code.
Patients And Methods: Two separate whole body Medical Internal Radiation Dosimetry (MIRD) phantoms have been defined simultaneously in a single Monte Carlo N-Particle (MCNP) input file as the patient and the caregiver. Two different groups of irradiation situations have been assumed for the caregiver related to the patient, (1) both the patient and the caregiver are standing and (2) the patient is lying in the bed while the caregiver is standing beside the patient.
