Phenylketonuria is an inborn error of amino acid metabolism that results in severe mental retardation if not treated early and appropriately. The traditional treatment, consisting of a low-phenylalanine diet, is usually difficult to maintain throughout adolescence and adulthood, resulting in undesirable levels of blood phenylalanine and consequent(More)
Two cell lines producing monoclonal antibodies have been established from peripheral blood of a negative Rhesus blood donor which has been immunized with positive Rhesus red blood cells. Two monoclonal antibodies Co II 8.8 and Co II 7.12 have been selected. Both are IgG1 antibodies, but recognize different epitopes on the Rhesus D antigen, apparently(More)
We have previously described the isolation of two hybridoma variants secreting higher avidity IgM (D5 and 7F5), starting from the E11 hybridoma cell line, which produces an antibody specific for the A Ag of the ABO blood group system. In order to explain at the molecular level this increased reactivity, cDNA encoding the H and L chains of the E11, D5, and(More)
The development of imaging devices adapted to small animals has opened the way to image-guided procedures in biomedical research. In this paper, we focus on automated procedures to study the effects of the recurrent administration of substances to the same animal over time. A dedicated system and the associated workflow have been designed to percutaneously(More)
Hepatocellular carcinoma (HCC) is one of the most common cancer related deaths worldwide. One of the main challenges in cancer treatment is drug delivery to target cancer cells specifically. Preclinical evaluation of intratumoral drugs in orthotopic liver cancer mouse models is difficult, as percutaneous injection hardly can be precisely performed manually.(More)
Somatic mutation in the Ig genes plays a major role in the increase of antibody affinity observed in secondary immunologic responses. It has been shown that the mechanism responsible for the high rate of somatic mutation in the Ig genes was active not only in normal B lymphocytes but also in B-cell hybridomas secreting mAb. Also, it has been reported that(More)
