    Bis-Schiff Base Derivatives of 2,5-Dihydroxybenzaldehyde: Synthesis, Characterization and Antimicrobial Activity of Their Cu(II), Co(II) and Zn(II) Complexes
    (TAYLOR & FRANCIS INC, 2013) Sahin, M.; Kocak, N.; Arslan, U.; Sahin, O.; Yilmaz, M.
    In this study, three Schiff base ligands (N,N-Bis(2,5-dihydroxybenzylidene)-4,4- diaminodiphenylmethane (DHDPM), N,N-Bis(2,5-dihydroxybenzylidene)- 1,2- diaminoethane (DHSalen) and N,N-Bis(2,5-dihydroxybenzylidene)- 1,3-phenylenedimethanamine (DHSalomphen)) and their metal complexes were synthesized and characterized by infrared spectroscopy (IR), thermogravimetric analysis (TGA), nuclear magnetic resonance (H-1 NMR), fluorescence spectra, elemental analysis and magnetic susceptibility apparatuses. The antibacterial activity was also studied against Staphylococcus aureusATCC 29213, Streptococcus mutansRSHM 676, Enterococcus faecalisATCC 29212, Lactobacillus acidophilus RSHM 06029, Escherichia coli ATCC 25922 and Pseudomonas aeruginosaATCC 27853.

    Comparison of bone scintigraphy and F-18-FDG PET-CT in a prostate cancer patient with osteolytic bone metastases
    (ELSEVIER SCIENCE INC, 2011) Kara, P. Ozcan; Kara, T.; Gedik, G. Kara; Sari, O.; Sahin, O.
    A 62 year-old male with prostate cancer, recently complaining lumbar pain with elevated PSA level (6.83 ng/ml) was referred for evaluating bone metastases. Bone scintigraphy with Tc-99m-MDP demonstrated intense uptake on third lumbar vertebra. Postoperative biopsy of the lesion on third lumbar vertebra revealed adenocarcinoma metastasis. For evaluating distant metastases and restaging, F-18-FDG PET-CT was performed postoperatively. On PET-CT imaging there were cervical and left parailiac lymph nodes with FDG uptake, destruction on third lumbar vertebra level and intense soft tissue mass FOG uptake on the same area. Additionally, FDG uptake was detected on right iliac crest. On the CT images obtained by integrated PET-CT scanner, this uptake was matching with lytic bone metastases. The superiority of F-18-FDG PET-CT for demonstrating osteolytic bone metastases compared to bone scintigraphy was presented in a case of prostate cancer in a patient with bone and lymph node metastases.
