Study of comparative proteome between normal and inverted karyotypes of human m...
de Souza Santos, John Lenon; Câmara, Alice Barros; Meira, Isabella Tanus Job e; Oliveira, Jonas Ivan Nobre Multipotent mesenchymal stem cells have been expanded in vitro for cellular therapy in numerous clinical settings without standardized culture conditions or quality-control schemes. The in vitro expansion is necessary to obtain sufficient cells for clinical applications. However, the expansion may induce genetic and functional abnormalities which may affect the safety and functionality of MSC, especially ...
Quantum molecular modelling of ibuprofen bound to human serum albumin
Dantas, Diego de Sousa; Oliveira, Jonas Ivan Nobre; Lima Neto, José Xavier de; Costa, Roner Ferreira da; Bezerra, Eveline MatiasThe binding of the nonsteroidal anti-inflammatory drug ibuprofen (IBU) to human serum albumin (HSA) is investigated using density functional theory (DFT) calculations within a fragmentation strategy. Crystallographic data for the IBU–HSA supramolecular complex shows that the ligand is confined to a large cavity at the subdomain IIIA and at the interface between the subdomains IIA and IIB, whose binding sites ar...
Biofísica molecular: do transporte eletrônico em sistemas biológicos à descriçã...
Oliveira, Jonas Ivan NobreEsta tese trata de duas pesquisas no campo da modelagem molecular, com diferentes naturezas conceituais, porém, baseadas em semelhantes princípios teóricos da física quântica e da química computacional. No primeiro estudo, com o intuito de esclarecer os aspectos estruturais e energéticos da estabilidade da tripla-hélice do colágeno humano, foram quantificadas as energias de interação entre os resíduos de aminoá...
Modelagem molecular na caracterização eletrônica de oligopeptídeos e na descriç...
Oliveira, Jonas Ivan NobreCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; In this dissertation, the theoretical principles governing the molecular modeling were applied for electronic characterization of oligopeptide α3 and its variants (5Q, 7Q)-α3, as well as in the quantum description of the interaction of the aminoglycoside hygromycin B and the 30S subunit of bacterial ribosome. In the first study, the linear and neutral...
