Large area patterned boron nanocones with low turn-on electric field of 2.8 V microm(-1) and low threshold electric field of 3.8 V microm(-1) were synthesized by a pre-manipulation to pattern the catalyst with a grid template as mask. The good field emission performance of patterned boron nanocones arise from the decreased screening effect and a favorable orientation of the nanocones. These res...
PURPOSE There is a clear need for a technique that provides subcellular locations of fluorine and boron atoms from fluorinated neutron capture agents because positron emission tomography is being tested as a tool for providing tumor boron concentrations in boron neutron capture therapy. EXPERIMENTAL DESIGN Ion microscopy was used in combination with confocal laser scanning microscopy to inves...
background: combination antiplatelet therapy is a classic treatment for percutaneous coronary intervention (pci) but this therapy increases gastrointestinal bleeding (gib). this study highlights the incidence of related risk factors of gib and endoscopic findings in patients with gib after pci and combination antiplatelet therapy. materials and methods: a standard check list was used to evaluat...
BACKGROUND In boron neutron capture therapy, blood boron concentration is the key factor to calculate radiation dose, however, blood sampling is difficult during neutron irradiation. MATERIALS AND METHODS The prediction of blood boron concentrations for BNCT treatment planning has been prospectively investigated using patient data obtained at first craniotomy after the infusion of a low dose ...
A lot of work has been performed in the area related to new fuel concepts to arrive efficient cycles neutronless and pB is the considered in our research. Conditions of degeneracy allow justifying the possibility to reduce the stringent ordinary conditions. The design of Jet Impact Inertial Fusion is one of the main items in DENIM research and simulations show a promising possibility avoiding a...
Boron-modified nucleic acids comprise a new set of DNA mimics that have potential biological and therapeutic applications. A series of nine dinucleotides containing N7-cyanoborane-2'-deoxyguanosine ((7b)dG) at the 3', 5' or both positions of the phosphodiester linkage have been synthesized using solution phase phosphoramidite chemistry. Fmoc was used as the 5'-protecting group because of incomp...
Superconducting wires are widely used for fabricating magnetic coils in fusion reactors. Superconducting magnet system represents a key determinant of the thermal efficiency and the construction/operating costs of such a reactor. In consideration of the stability of 11B against fast neutron irradiation and its lower induced radioactivation properties, MgB2 superconductor with 11B serving as the...
The melanin precursor analogue p-boronophenylalanine (BPA) has been used to deliver 10B to melanoma tissue for boron neuron capture therapy. Uptake studies in tumor models other than melanoma now indicate that BPA is capable of delivering therapeutic amounts of boron to tumors other than melanoma. The KHJJ murine mammary tumor carried s.c. in BALB/c mice, the GS-9L rat glioma carried both s.c. ...
Background: The purpose of this paper is to establish an easy and reliable biodosimeter protocol to evaluate the biological effects of proton beams. Materials and Methods: Human peripheral blood lymphocytes were irradiated using proton beams (LET: 34.6 keV μm−1), and the chromosome aberrations induced were analyzed using cytokinesis-blocked (CB) micronucleus (MN) assay. To determine th...
The application of immunoprotein-based targeting strategies to the boron neutron-capture therapy of cancer poses an exceptional challenge, because viable boron neutron-capture therapy by this method will require the efficient delivery of 10(3) boron-10 atoms by each antigen-binding protein. Our recent investigations in this area have been focused on the development of efficient methods for the ...
