Tetra phenoxy-3-methoxybenzoic acid substituted Co(II) and Cu(II) metal phthalocyanine compounds were reported for the first time. The structures of these compounds were elucidated by NMR, FT-IR, UV-vis spectroscopy, and elemental analysis. The UV/Vis, fluorescence spectra, viscosity and the thermal melting point techniques were implemented to analyze the DNA bonding activities of cobalt (II) and copper (II) complexes of phthalocyanine by calf thymus DNA. These techniques showed that the phthalocyanine complexes interacted with the DNA molecule through the intercalation mechanism. Additionally, among the methods above, the binding properties of DNA with the compounds 4 and 5 were studied by means of the agarose gel electrophoresis method. The complexes 4 and 5 bonded to the DNA molecule in the buffer system at a pH of 7.02. The findings of these methods proved that the Co(II) and Cu(II) complexes of phthalocyanine could be evaluated as potential cancer medicine for cancer treatment in the near future.
Temporary Changes in Neutrophil-To Platelet-To Ratios, and Mean Platelet Volume Reflecting the Inflammatory Process After Radioiodine Therapy

ObjectiveData on the effects of radioiodine (RAI) therapy on systemic inflammation are very limited. The aim of this study is to explore alterations of subclinical systemic inflammatory markers, such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and mean platelet volume (MPV), after RAI therapy in patients with differentiated thyroid carcinoma (DTC).Materials and methodsWe evaluated 57 DTC patients treated with RAI (RAI group), 37 DTC patients not treated with RAI (non-RAI control group), and 37 age-matched healthy individuals (healthy control group). NLR, PLR, and MPV levels were compared among the study groups; these were also examined after RAI in the RAI group.ResultsInitially, NLR was significantly higher in the RAI group than in the healthy controls. NLR and PLR increased significantly and MPV decreased significantly 2 months after RAI therapy (P=0.021, 0.001, and 0.008, respectively). Although NLR and PLR levels decreased, they were still high compared with the preoperative values. MPV returned to normal levels at 6 months. These parameters did not change significantly in the non-RAI control group.ConclusionThis is the first study to evaluate changes in NLR, PLR, and MPV after RAI therapy. Our findings suggest that NLR, PLR, and MPV changes indicate systemic inflammation that occurs after RAI therapy because of thyroid remnant tissue ablation.
