IMPORTANCE OF THE FIELD Tumor targeting with peptides is based on the discovery that receptors for many regulatory peptides are overexpressed in tumor cells, compared with their expression in normal tissues. Consequently, these peptides and their analogues can be used as carriers/targeting moieties for the preparation of diagnostic and therapeutic agents that have increased selectivity and decr...

In this work, the physicochemical characterization of liposomes loaded with a newly synthesized carboranyl porphyrazine (H2HECASPz) is described. This molecule represents a potential drug for different anticancer therapies, such as boron neutron capture therapy and for photodynamic therapy or photothermal therapy. Different loading methods and different lipid mixtures were tested. The correspon...

PURPOSE Boron neutron capture therapy (BNCT) is a radiotherapeutic modality based on (10)B(n,alpha)(7)Li reaction, for the treatment of malignant gliomas. One of the main limitations for BNCT effectiveness is the insufficient intake of (10)B nuclei in the tumor cells. This work was aimed at investigating the use of L-DOPA as a putative enhancer for (10)B-drug 4-dihydroxy-borylphenylalanine (BPA...

The vitamin D nuclear receptor (VDR) is a potential target for cancer therapy. It is expressed in many tumors and its ligand shows anticancer actions. To combine these properties with the application of boron neutron capture therapy (BNCT), we design and synthesize a potent VDR agonist based on the skeleton of the hormone 1α,25-dihydroxyvitamin D3 (1,25D) and an o-carborane (dicarba-o-closo-1,2...

Introduction: Recently head and neck cancer has pay attention to many researchers. Its therapeutic methods include surgery, chemotherapy, radiotherapy and Boron neutron capture therapy (BNCT). BNCT is better than conventional radiotherapy because it targets the tumor cell. This method involves two steps of infusion of stable 10B and then neutron radiation with a suitable intens...

Abundance observations indicate the presence of rapid-neutron capture (i.e., rprocess) elements in old Galactic halo and globular cluster stars. These observations demonstrate that the earliest generations of stars in the Galaxy, responsible for neutron-capture synthesis and the progenitors of the halo stars, were rapidly evolving. Abundance comparisons among large numbers of stars provide clue...

Gadolinium (Gd) neutron capture plays an important role in both Gd neutron capture therapy and neutron detection. Detailed information about the lowenergy electron spectrum emitted after Gd neutron capture is essential for accurately determining the dose delivery to the target and healthy tissues, as well as the effectiveness of Gd against other neutron convertors such as boron (B) and lithium ...

An accelerator-based BNCT (Boron Neutron Capture Therapy) facility is now under construction and the entire system including the patient treatment system will be installed in the Ibaraki Medical Center for Advanced Neutron Therapy (tentative name). Investigation of an 8-MeV proton linac and of a beryllium-based neutron production target for the BNCT is progressing. We are aiming at the design a...

This review compares the safety and efficacy of boron neutron capture therapy (BNCT) in the treatment of previously irradiated, inoperable locoregional recurrent HNC patients and compares BNCT against the standard treatment of platinum-based chemotherapy. Our analysis of published clinical trials highlights efficacy of BNCT associated with mild side effects. However, the use of BNCT should be e...
