β-Lapachone is a phytochemotherapeutic originally isolated from Lapacho tree whose extract has been used medicinally for centuries. It is well known that NAD(P)H:quinone oxidoreductase (NQO1) activity is the principal determinant of β-Lapachone cytotoxicity. As NQO1 is overexpressed in most common carcinomas, recent investigations suggest its potential(More)
Melanoma is among the most aggressive and treatment-resistant human skin cancer. Photodynamic therapy (PDT), a minimally invasive therapeutic modality, is a promising approach to treating melanoma. It combines a non-toxic photoactivatable drug called photosensitizer with harmless visible light to generate reactive oxygen species which mediate the antitumor(More)
As with natural ecosystems, species within the tumor microenvironment are connected by pairwise interactions (e.g. mutualism, predation) leading to a strong interdependence of different populations on each other. In this review we have identified the ecological roles played by each non-neoplastic population (macrophages, endothelial cells, fibroblasts) and(More)
Brugada Syndrome (BS) is a polygenic inherited cardiac disease characterized by life-threatening arrhythmias and high incidence of sudden death. In this study, two-dimensional gel electrophoresis (2D-PAGE) coupled to mass spectrometry (LC-MS/MS) was used to investigate specific changes in the plasma proteome of BS patients and family members sharing the(More)
Photodynamic therapy (PDT) leads to the generation of cytotoxic oxygen species that appears to stimulate several different signaling pathways, some of which lead to cell death, whereas others mediate cell survival. In this context, we observed that PDT mediated by methyl-5-aminolevulinic acid as the photosensitizer resulted in over-expression of survivin, a(More)
Photodynamic therapy is a minimally invasive and clinically approved procedure for eliminating selected malignant cells with specific light activation of a photosensitizer agent. Whereas interstitial and intra-operative approaches have been investigated for the ablation of a broad range of superficial or bulky solid tumors such as breast cancer, the(More)
The study of cellular interactions in the tumor microenvironment has become one of the main areas of research in the fight against cancer. Tumor-associated macrophages (TAMs) influence tumor progression and therapy response due to its functional plasticity. Regarding cancer treatment, photodynamic therapy (PDT) is a minimally invasive and clinically(More)
Photodynamic therapy (PDT), a promising treatment option for cancer, involves the activation of a photosensitizer (PS) by local irradiation with visible light. Excitation of the PS leads to a series of photochemical reactions and consequently the local generation of harmful reactive oxygen species (ROS) causing limited or none systemic defects. However, the(More)
The Authors show their preliminary experience with the sentinel lymph node biopsy (SLNB) in clinical early invasive breast cancer (T1N0). During a period of 15 months, forty-two patients were submitted to SLNB upon Tc99-colloid albumin injection and SLN identification by lymphoscintigraphy. The middle number of lymph nodes found in the SLNB was 1 (1-3),(More)
Intradialytic hypotension (IDH) is a still-frequent and poorly-understood complication of haemodialysis. Haemofiltration has recently been shown to reduce the phenomenon of IDH. HFR-Aequilibrium adds to traditional HFR and is, in practice, a variant comprising endogenous re-infusion of haemodiafiltration with dialysate sodium concentration and(More)
