- Characterization of CYP2C19*17 polymorphism in a Portuguese population sample relevant for proton pump inhibitor therapy : a pilot studyPublication . Ferraz, Adriana M. L.; Bandarra, Susana; Mascarenhas, Paulo; Barahona, Isabel; Martins, Rui; Ribeiro, Ana ClaraThe interindividual variability of Proton Pump Inhibitor (PPI) therapy results from the phenotype variability associated with the cytochrome P450 2C19 (CYP2C19) gene, namely the CYP2C19*17 allele. Our aim was to characterize patients’ genetic variability undergoing PPI therapy. A sample of 33 oral mucosa cells from Portuguese pharmacy patients was collected, followed by genotyping. The allelic frequencies of CYP2C19*1 (-806C) and CYP2C19*17 (-806T) were 71.2% and 28.8%, respectively. The genotypic frequencies for CYP2C19*1/*1 and CYP2C19*1/*17 were 42.4% and 57.6%, respectively, and 19 of these patients may have a Rapid Metabolizer (RM) phenotype pharmaceutical opinion letter, based on genetic evidence.

- Evaluation of the cytotoxic potential of adhesives, with two on the market: Scotchbond Universal and Optibond Solo Plus, and an adhesive in the experimental phase: T1Publication . Santos, Sofia; Mascarenhas, Paulo; Bandarra, Susana; Ribeiro, Ana Clara; Maurício, Paulo; Barahona, IsabelIn vitro studies evaluating the cytotoxic potential of substances released from dental adhesives are lacking. The purpose of this study was to compare the cytotoxicity of the extracts of dental adhesives Scotchbond Universal and Optibond Solo Plus, and an adhesive in the experimental phase: T1. 3T3 mouse fibroblast cells and MG-63 osteoblast-like cells from human osteosarcoma were exposed for 24 h to serial extract dilutions. Cytotoxicity was determined using an MTT assay. For both cell lines, the cytotoxicity order obtained, of the unfiltered adhesive extracts, was T1 (less cytotoxic) < Optibond Solo Plus < Scotchbond Universal (most cytotoxic).

- Massive testing Is important to control a SARS-CoV-2 outbreakPublication . Guerreiro, Daniela; Costa, Ana Luísa; Nascimento, Teresa; Ribeiro, Ana Clara; Proença, Luís; Mendes, José João; Barroso, HelenaAt the end of September 2020, an outbreak of SARS-CoV-2 occurred at a university student’s residence. A rapid response, with massive testing, using both RT-PCR and antigen rapid testing, helped to control the spread of the virus, showing the importance of tracking the infection. Testing for antibodies one month after the outbreak showed that the permanence of students with no infection in the same building was not a preponderant factor to develop an immune response.
