The antitumor activity of the organometallic ruthenium(II)-arene complexes, RuCl(2)(eta(6)-arene)(PTA), (arene = p-cymene, toluene, benzene, benzo-15-crown-5, 1-ethylbenzene-2,3-dimethylimidazolium tetrafluoroborate, ethyl benzoate, hexamethylbenzene; PTA = 1,3,5-triaza-7-phosphaadamantane), abbreviated RAPTA, has been evaluated. In vitro biological(More)
Although it is well recognized that cell-matrix interactions are based on both molecular and geometrical characteristics, the relationship between specific cell types and the three-dimensional morphology of the surface to which they are attached is poorly understood. This is particularly true for glomerular podocytes - the gatekeepers of glomerular(More)
1. Spatially resolved X-ray fluorescence (XRF) spectroscopy with synchrotron radiation is a technique that allows imaging and quantification of chemical elements in biological specimens with high sensitivity. In the present study, we applied XRF techniques at a macro and micro level to carry out drug distribution studies on ex vivo models to confirm the(More)
We investigated the molecular events of the ruthenium complex NAMI-A (0.1 mM for 1 h) on cell cycle G2-M arrest in KB carcinoma cells. Flow cytometry analysis showed a progressive accumulation of cells in S phase at 16 h, and in G2-M phase at 20 h after the end of treatment. NAMI-A pre-mitotic stop to cell proliferation was due to the maintenance of the(More)
This work aims to assess the feasibility of studying the distribution of drugs and diagnostic agents in biological specimens by means of XRF detected with high-resolution and high sensitivity Silicon Drift Detectors. In the present study we have employed as diagnostic agent a gadolinium complex (Gadocoletic acid trisodium salt - B22956/1). The primary(More)
