We identified the AQP-2 gene mutation (R254Q) in a family with dominant NDI. The patient studied here has NDI with partial response to the anti-diuretic effect of AVP and dDAVP. Hereditary NDI seems to have the uniform clinical manifestations, but this might only reflect the information on screened patients with clear clinical presentations. It may be that a milder form of NDI has been overlooked due to a lack of genetic identification. Gene mutation analysis should be considered even in patients with mild NDI symptoms. Fortunately, both V2R and AQP2 genes are small and can be easily analyzed.

SUMMARYAn Al-N system optical absorption layer has been developed, to be used for Al-based metal mesh electrodes on touch screen panels. The triple-layered electrode effectively suppresses the optical reflection in both visible light and the blue color region and exhibits excellent wet etching property that accommodates micro-fabrication. Due to its high noise immunity and contact sensitivity originating from its low electrical resistivity, the proposed metal mesh electrodes are useful for touch-sensitive panels in the next generation ultra-high-resolution displays. key words: touch screen panel, metal mesh electrode, projected capacitive, invisible, etching property
