Ag nanoparticles were deposited on TiO2 films (Ag/TiO2 films) by photocatalytic means. When the film was immersed in various kinds of alcohols, the linear relationship was observed between the wavelength of localized surface plasmon resonance peak and the refractive index of the alcohols in the range of 1.33–1.41. The Ag/TiO2 films can be applied to the SPR sensors.

A 31-year old woman was admitted to our clinic complaining of high blood pressure, dizziness, constipation, mental irritability and weight loss. The physical examination revealed goiter in her neck. The plasma levels of norepinephrine and epinephrine were 3.45 and 0.76 ng/ml, respectively. Urinary excretion of norepinephrine was 1 mg and epinephrine was 32.2 micrograms/24-hours. The examination by radiography and radioactive isotope revealed a tumor in the left adrenal region and another in the left lower lobe of the thyroid. After the operations, pheochromocytoma and papillary adenocarcinoma of the thyroid gland were recognized pathologically. However, 17 months later, the recurrence of pheochromocytoma in the contralateral adrenal region was discovered and removed. Although the co-existence of bilateral pheochromocytoma and papillary adenocarcinoma of the thyroid gland is not one of multiple endocrine neoplasia, to the best of our knowledge, only 7 such cases have been reported in the published literature.

Negative muons are important probes that enable us to investigate non-destructively the elemental composition in thick-layered samples. This method has already shown successful results for the elemental analysis of cultural heritage artifacts. Now, its success attracts also the interest of industrial device developers who want to know non-destructively the inside of a device during switch-on state. At J-PARC MUSE, in response to such needs, we have developed an analysis system with higher detection efficiency to increase opportunities for analyzing many new device samples. This report describes the chamber design and the results obtained from a first test experiment.
