In this paper, we have proposed a new heating method in which high frequency electric fields in a re-entrant type resonant cavity are used for the heating of deeply seated tumors. In this method, a human head is placed between the gap of the inner re-entrant cylinders, and is heated with electromagnetic fields stimulated in the cavity without contact between the surface of the human head and the applicator...
This paper discusses a new method to control the heating area of a re-entrant resonant cavity applicator for brain tumor hyperthermia treatment non-invasively. We have already discussed about the effectiveness of a developed system with experiments of heating an agar phantom and computer simulations. Here, in order to heat a deep brain tumor, we propose the heating method of using several electromagnetic...

This paper discusses new methods to control the heating pattern of the prototype resonant cavity applicator for deep tumor hyperthermia treatment. We have already confirmed the effectiveness of the developed heating system with experiments using agar phantoms and computer simulations. Here, the following two methods to control the heating pattern were proposed. In the first method, a human body, which...

Aims/hypothesis Type 1 diabetes mellitus is caused by autoimmune pancreatic beta cell destruction, and the destructive process involves several molecular mechanisms including oxygen-reactive species. A cysteine derivative, N-acetyl-cysteine, is widely used as an antioxidant, but the role of N-acetyl-cysteine in the protection of pancreatic beta cells in Type 1 diabetes remains unclear. The aim of...
From the reflection spectra of tin tetraiodide (SnI 4 ) single crystals, the exciton absorption band has been observed at peak energies of 3.14 eV (77 K) and 3.07 eV (room temperature). The exciton binding energy is estimated at 380 meV. The large binding energy suggests that each SnI 4 molecule has a quantum dot-like character. The reflection spectra of the SnI 4 clusters...
