One of the major angiogenic factor released by tumor cells is VEGF. Its high expression is correlated with poor prognosis in colorectal tumors. In colon cancer, gastrin gene expression is also upregulated. In these tumors, gastrin precursors are mainly produced and act as growth factors. Recently, a study has also shown that the gastrin precursor, G-gly(More)
A simple electrochemical sandwich immunoassay involving a polystyrene microarray slide coated with monoclonal capture antibodies and carbon screen-printed sensors (SPS) was designed for the rapid diagnosis of respiratory syncytial virus (RSV). The detection of the antibody-antigen complex formation relied on the use of a horseradish peroxidase conjugate.(More)
BACKGROUND Sample quality is a fundamental parameter for the successful diagnosis of respiratory viruses. This parameter depends upon the concentration of epithelial cells. Respiratory samples are usually heterogeneous, which makes relative quantification of the viral load, against the quantity of cells, the most suitable measurement. The quantification of(More)
BACKGROUND Respiratory viral diagnosis of upper respiratory tract infections has largely developed through multiplex molecular techniques. Although the sensitivity of different types of upper respiratory tract samples seems to be correlated to the number of sampled cells, this link remains largely unexplored. METHODS Our study included 800 upper(More)
