Canine nail bed keratoacanthoma diagnosed by immunohistochemical analysis.

A 10-year-old, Shih Tzu dog was presented with an enlarged, curled 2nd nail in the left forelimb. Digital amputation was performed and the mass was diagnosed as a nail bed keratoacanthoma (infundibular keratinizing acanthoma) histopathologically. There was no recurrence postoperatively.

Quantitative assessment of neurochemical changes in a rat model of long-term alcohol consumption as detected by in vivo and ex vivo proton nuclear magnetic resonance spectroscopy.

The aim of present study was to quantitatively investigate the neurochemical profile of the frontal cortex region in a rat model of long-term alcohol consumption, by using in vivo proton magnetic resonance spectroscopy ((1)H-MRS) at 4.7 T and ex vivo(1)H high-resolution magic angle spinning (HR-MAS) technique at 11.7 T.
