Ammonium acid urate (AAU) urolithiasis is a rare condition; however, it is endemic in some countries, with an especially high incidence in Asia. This study was conducted to investigate the special presentation of patients with AAU urolithiasis in Taiwan. Reports of 3457 stones were retrospectively reviewed from January 2005 to January 2010 and 25 patients(More)
Pheochromocytomas and paragangliomas (extra-adrenal pheochromocytomas) are catecholamine-secreting tumors. The paraganglioma of the urinary bladder is an uncommon neoplasm with a higher malignancy rate. Only about 60% of bladder paragangliomas presented with hematuria, and most of them were microscopic hematuria. Herein, we report two cases of bladder(More)
t-{Fe(abpt)(2)[N(CN)(2)](2)} [abpt = 4-amino-3,5-bis(pyridin-2-yl)-1,2,4-triazole] is an intriguing spin-crossover system that crystallizes in two polymorphs. Polymorph A is paramagnetic; its crystal structure consists of a single molecule located at the center of inversion symmetry. Polymorph B, on the other hand, exhibits a rather complicated(More)
Two polymorphs of mononuclear six-coordinate iron(II) spin-crossover complex trans-[Fe(tzpy)(2)(NCS)(2)] (tzpy = 3-(2-pyridyl)[1,2,3]triazolo[1,5-a]pyridine) (1) were isolated and structurally characterized. According to the thermally dependent magnetic measurements, polymorph A undergoes a gradual spin transition from a paramagnetic high-spin state(More)
