OBJECTIVE To evaluate the relationship between two year PSA nadir (PSAn) after brachytherapy and biochemical recurrence rates in prostate cancer patients. MATERIALS AND METHODS In the period from January 1998 to August 2007, 120 patients were treated with iodine-125 brachytherapy alone. The results analysis was based on the definition of biochemical(More)
The coordination compound of the antihypertensive ligand irbesartan (irb) with copper(II) (CuIrb) was synthesized and characterized by FTIR, FT-Raman, UV–visible, reflectance and EPR spectroscopies. Experimental evidence allowed the implementation of structural and vibrational studies by theoretical calculations made in the light of the density functional(More)
The oxidovanadium(IV) complex of oxodiacetic acid (H2ODA) and dppz (dipyrido[3,2-a:2′,3′-c] phenazine) of stoichiometry [VO(ODA)(dppz)]⋅3H2O could be synthesized for the first time by reaction between [VO(ODA)(H2O)2] and dppz. It was characterized by infrared and electronic spectroscopies. Its optimized molecular structure was obtained by DFT calculations,(More)
Norfloxacin is a fluoroquinolone antibiotic used in the treatment of bacterial infections. In this article, we studied the potential antitumoral action of a complex of Norfloxacin with Cu(II), Cu(Nor)2·5H2O on osteosarcoma cells (UMR106) and calvaria-derived cells (MC3T3-E1), evaluating its cytotoxicity and genitoxicity. We have also elucidated the more(More)
