“…Fluorescent probes have been regarded as highly efficient tools for ion detection due to their advantages, such as simple synthesis steps, easy manipulating procedures, inexpensive cost, good selectivity and sensitivity, and naked-eye detection. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] Among them, diaminomaleonitrile derivation has been one of the most attractive approaches for its easy modulation, usually turn-on fluorescent response, and high selectivity to Cu 2+ . [24][25][26][27][28][29][30][31][32][33][34] And so far, most of the reports have attributed fluorescence enhancement to metal-complexation, 24,25,33,34 while direct evidences are needed for more investigations.…”

A colorimetric and turn-on fluorescent chemodosimeter 1 based on diaminomaleonitrile was synthesized for Cu 2+ detection. It showed high selectivity and sensitivity towards Cu 2+ over the other tested metal ions. Probe 1 in acetonitrile exhibited a strong absorption band at 530 nm and weak fluorescence emission when excited at 480 nm, while the addition of Cu 2+ could lead to a 30-nm blue shift of the absorption band and a remarkable fluorescence enhancement. Moreover, the detection limit of probe 1 for Cu 2+ was calculated to be 28 nM. Quite different from the reported mechanism based on a metal-complexation induced fluorescence enhancement, the sensing mechanism was proved to be based on the Cu 2+-promoted hydrolysis reaction, which was confirmed by 1 H NMR, 13 C NMR and mass spectrum analysis. Studies on probe 2 were carried out to verify the universality of this sensing mechanism.

Gartner's duct cysts often occur in the deep and anatomically inaccessible areas of the pelvis and are therefore difficult to diagnose and treat. We report a case of a Gartner's duct cyst that was diagnosed using laparoscopic biopsy and was treated with tetracycline sclerotherapy. A 43-year-old woman was referred to our hospital with lower urinary tract symptoms. Magnetic resonance imaging of the pelvis revealed a multilocular cystic tumor (40 mm × 25 mm) between the bladder and the anterior vaginal wall. Image-guided transvaginal fine-needle aspiration was performed, and
