The full spectrum of Df3 and Dl4 semileptonic decays can be precisely measured at a Tau Charm Factory. Sensitivety to rare semileptonic decays extends to branching fractions as small as 10m3. Improved measurements of Cabibbo-Kobayashi-Maska wa matrix elements V,, and Vcd can be obtained. With an improved theoretical understanding, semileptonic measurements can test the unitarity of the second r...
Acanthamoeba keratitis (AK) is a corneal disease caused by members of a genus of free-living amoebae and is associated predominantly with contact lens (CL) use. This study reports 16 cases of culture-proven AK diagnosed in northern Italy. Genotype identification was carried out with a PCR assay based on sequence analysis of the 18S rRNA gene, and sensitivity and specificity were evaluated in co...
In this study, 15 Acanthamoeba isolates from AK patients and 10 environmental samples (water, soil and animal-origin samples) were classified at the genotype level based on the sequence analysis of the Diagnostic Fragment 3 (DF3) of Acanthamoeba small subunit rRNA gene. The obtained results revealed that most of these Acanthamoeba strains belonged to genotype T4 both in clinical and environment...
Pleural fluid levels of the cancer antigen 15-3 (CA15-3) detected by monoclonal antibodies (115D8 and DF3) were determined in 40 patients with carcinomatous pleural effusions and in 41 patients with tuberculous pleural effusions. Using a cut off level of 16 U/ml, 15 of the 40 carcinomatous fluids but none of the 41 tuberculous fluids were positive. Pleural fluid levels of CA15-3 were not correl...
