Eight BODIPY dyes were synthesized and used as photosensitizers (PSs) on the human colon carcinoma cell line HCT116. In this panel of molecules, the structure varies in the substituents on pyrrole 2, 6 positions and on the phenyl ring at the indacene 8 position. For these compounds relevant physico-chemical parameters, such as singlet oxygen production,(More)
We present the case of a 52-year-old man with a 2-month history of dyspnea, bilateral pleural effusion and cardiomegaly of rapid onset. A cardiac ultrasound showed pericardial effusion with infiltration of the infero-lateral cardiac wall, right auricle and aortic arch by a mass of unknown origin. Despite 1% blast cells in the peripheral blood, 2 bone marrow(More)
OBJECTIVE Type 2 diabetes mellitus (T2DM) is associated with endothelial dysfunction, characterized by a reduction of nitric oxide (NO)-mediated relaxation. Phosphodiesterase type 5 inhibitors (PDE5i) improve NO levels. The aim of the study was to investigate whether long-term, chronic treatment with the PDE5i vardenafil improves systemic endothelial(More)
The HERPCHEK herpes simplex virus (HSV) antigen test (Du Pont, Billerica, Mass.) is a biotinstreptavidin-amplified enzyme-linked immunoassay for the detection of HSV antigen directly in clinical specimens. In a total of 200 mucocutaneous specimens, predominantly lesions from nongenital sites, HERPCHEK had a sensitivity of 90% and a specificity of 99%(More)
To investigate whether long-term, chronic treatment with the phosphodiesterase-5 inhibitor vardenafil affects adrenal and testicular steroidogenesis in diabetic men, using liquid chromatography-tandem mass spectrometry. A longitudinal, prospective, investigator-started, randomized, placebo-controlled, double-blind, clinical-trial was carried out, enrolling(More)
