BACKGROUND In neutron interaction with matter and reduction of neutron energy due to multiple scatterings to the thermal energy range, increasing the probability of thermal neutron capture by neutron captures makes dose enhancement in the tumors loaded with these materials. OBJECTIVE The purpose of this study is to evaluate dose distribution in the presence of 10B, 157Gd and 33S neutron captu...

河 合建一,牧 廣 利,赤 星光彦1京 都大学原子炉実験所,大 阪府泉南郡熊取町 野田,〒590-04 An absorbed dose in amoeba irradiated by thermal neutrons was estimated. Nuclear events following to thermal neutron capture were divided into 6 parts. More than 99% of absorbed dose was estimated to be due to capture ƒÁ-rays. Absorbed dose due to recoil nucleus following to the emission of capture ƒÁ-rays and that due to ƒÀor ƒÁ-rays emitted ...

The aim of this study was to evaluate the anti-nociceptive effects of a low, sub-effective dose of amitriptyline, in combination with the different doses of ethanolic and aqueous extracts of Crocus sativus following sciatic nerve chronic constriction injury (CCI) in rats. Amitriptyline (3, 10 and 30 mg/kg, i.p.) and the extracts (25, 50 and 100 mg/kg, i.p.), were separately administered at the ...

in this study the effect of the alkylating agent, sulfur mustard, on calf thymus chromatin was investigated using uv/vis spectroscopy, gel electrophoresis and thermal denaturation techniques. the results show that treatment of isolated chromatin with sulfur mustard releases histones from the core particles but does not affect histone h i and nonhistone chromosomal proteins. the content of relea...

This study investigates the temperature and thermal dose of a tumor in hyperthermia therapy with non-local equilibrium. The thermal model assumes the tissue with blood vessel distribution as a porous media and uses the convection terms instead of perfusion terms in energy conservation equations for both tissue and blood. By using numerical method, this study calculates the temperature and therm...

PURPOSE Randomized clinical trials have demonstrated hyperthermia (HT) enhances radiation response. These trials, however, generally lacked rigorous thermal dose prescription and administration. We report the final results of a prospective randomized trial of superficial tumors (</= 3 cm depth) comparing radiotherapy versus HT combined with radiotherapy, using the parameter describing the numbe...

This paper investigates how the thermal diffusion of boron in silicon is influenced by a high energy fluorine implant with a dose in the range 531014–2.331015 cm−2. Secondary Ion Mass Spectroscopy (SIMS) profiles of boron marker layers are presented for different fluorine doses and compared with fluorine profiles to establish the conditions under which thermal boron diffusion is suppressed. The...
