A simple and efficient fluorescent chemosensor for Al(3+) is reported in the paper. The chemosensor is obtained by dehydration reaction of 2-hydroxy-1-naphthaldehyde and 2-aminophenol. The chemosensor has high selectivity and sensitivity for Al(3+) and displays fluorescence "off-on" switch signal. The detection limit of the chemosensor for Al(3+) can reach(More)
The title compound, C15H17NO4, containing two mol-ecules in the asymmetric unit is a polymorph of the crystal structure published by Martínez et al. [(2011). Eur. J. Org. Chem. pp. 3137-3145] which at 120 K is monoclinic with one mol-ecule in the asymmetric unit. Both mol-ecules in the title compound are in the trans form. In the crystal, N-H⋯O and O-H⋯O(More)
Spinal synovial sarcoma (SS) is an extremely rare malignant tumor in children. We report an unusual pediatric synovial sarcoma located in the thoracic spine at T9–T10 levels. A 10-year-old boy was admitted with a 1-month history of progressive back pain and low fever for 7 days as well as sudden onset of paraplegia for 1 day. The primary diagnosis was(More)
Giant pediatric intracranial tumor (GPIT) remains to be a challenging disease with high morbidity and mortality. The clinical data of 60 patients under 18 years of age operated on with GPIT (≥5 cm in diameter) were retrospectively analyzed. Gross total resection was achieved in 46 cases (77%) and subtotal resection was obtained in 14 cases (23%). Ninety(More)
There are two independent mol-ecules and one toluene solvent mol-ecule in the asymmetric unit of the title compound, C(25)H(12)Br(4)·0.5C(7)H(8). The dihedral angles between the fluorene ring systems are 85.30 (6) and 84.95 (6)° in the two mol-ecules. The disortions in angles from the ideal sp(3)-hybridization geometry around the tetra-hedral C atoms are(More)
