The purpose of this work is to compare the chemical behavior of humanized AcMs vs. human IgG radiolabeled with 99mTc. To this end, 3 immunoglobulins were analyzed, the IgG (human), the humanized monoclonal antibody R3 (AcM-R3h) and the humanized monoclonal antibody T1 (AcM-T1h). The results obtained reveal slight differences as regards the behavior of these immunoglobulins before the labeling with 99mTc, which shows differences in the chemical behavior of these proteins. Although in theory the modifications that are made to the AcMs in order to humanize them must not affect their chemical behavior, the obtained data indicate that the conditions for their radiolabeling should not be extrapolated from other proteins; on the contrary, particular procedures should be elaborated for each AcM-h.

The article presents the results of a survey conducted with Spanish and Italian university professors regarding the use of web 2.0 teaching tools during the COVID-19 pandemic. The results show that the perception of change is high and mainly depends on the professor's psychographic characteristics. The similarities and differences between the samples of university professors from both countries are discussed. Additionally, the importance of universities designing short, medium, and long-term strategies for university faculty to adapt their teaching to future lockdowns resulting from disease outbreaks is highlighted.

The present paper shows the design, optimization, quality control for testing radiochemical purity, biological quality and realtime stability studies of a preparation of macroaggregated albumin from the controlled denaturation of HSA. An experimental design with a 2³ factorial plan was carried out in order to determine the ideal conditions for the preparation. The results showed that variations of albumin concentrations within the range of 5-15 mg/mL were irrelevant, however, the final pH of the mixture and the stirring speed were significant variables, as well as their interaction. Formulations with particles of diameter between 11 and 80 μ were obtained with the conditions selected in the experimental design which met the internationally established criteria for radiochemical purity, sterility and apyrogenicity. The biodistribution in experimental animals showed good quality lung images. The produced lots maintained physical, radiochemical, biological and microbiological stability during 90 days of storage at 4 °C. [ABSTRACT FROM AUTHOR]
