A trans-Ferulic acid based fluorescence "turn-on" chemosensor for aluminum (III) ions in live cells and environmental samples.

This study introduces a novel fluorescence 'turn-on' chemosensor, FHDA, based on a trans-Ferulic acid Schiff-base derivative. FHDA stands out as a highly selective and sensitive tool for the fluorescent detection of Al3 with the fluorescence 'turn-on' effect. FHDA exhibits a strong CHEF effect and ICT upon complexation with Al in a 1:2 binding stoichiometry.

Use of an aortic stent graft extension for the treatment of urethral stricture in a dog.

A 2-year-old male mixed dog was referred to us for further evaluation and treatment of a 4-week-history of oliguria and abdominal distension after a surgical repair of urethral injury. To relieve the urethral stricture, we placed a self-expanding aortic stent graft extension with a partial coverage with an expanded polytetrafluoroethylene (ePTFE). After the placement of the stent, the dog presented with a normal urinary voiding, despite the presence of urinary incontinence.
