Identificação única de pacientes em fontes de dados distribuídas e heterogêneas

Soares, Vinícius de Freitas 25 August 2009 (has links)
Made available in DSpace on 2016-12-23T14:33:39Z (GMT). No. of bitstreams: 1 dissertacao.pdf: 2082796 bytes, checksum: e50f1bc16d61a50d4c9fb2e41ecd3cd5 (MD5) Previous issue date: 2009-08-25 / No decorrer de sua vida, um paciente é atendido por várias instituições de saúde e é submetido a uma série de procedimentos. A quantidade de informações armazenadas sobre esse paciente é crescente, tanto em volume quanto em diversidade. Existem ainda diferentes identificações para um mesmo paciente, gerando alto custo com duplicação de procedimentos e colaborando com a imprecisão dos diagnósticos e tratamentos. Nesse sentido, o presente trabalho utiliza técnicas de Record Linkage e geração de MPI (Master Patient Index), combinadas com as especificações do perfil de integração PIX (Patient Identifier Cross-Referencing), para estabelecer uma identificação única de pacientes em diferentes sistemas de informação em saúde, que contenham fontes de dados heterogêneas e distribuídas. Com a utilização desses conceitos e tecnologias, foi especificado um projeto e desenvolvido um protótipo de um IHE (Integrating the Healthcare Enterprise)/PIX. Experimentos foram realizados em três cenários com dados reais.

Nové regulační mechanismy nukleace mikrotubulů / New regulatory mechanisms of microtubule nucleation

Černohorská, Markéta January 2016 (has links)
MT nucleation from γ-tubulin complexes, located at centrosome, is an essential step in the formation of MT cytoskeleton. In mammalian cells, -tubulin is encoded by two genes. We functionally characterized two γ-tubulin proteins and have found that both are functionally equivalent. γ-Tubulin 2 is able to substitute for γ-tubulin 1 in MT nucleation. However, we revealed that unlike TUBG1, TUBG2 expression is downregulated in mouse preimplantation development. Mast cells represent effectors of the allergy reaction. Their activation by antigen induces number of cellular processes such as degranulation, proliferation and cytoskeleton rearrangements. The regulatory mechanisms of MT reorganization during mast cell activation are unknown. We identified new signaling proteins, GIT1 and PIX that interact with - tubulin. Depletion of GIT1 or PIX leads to changes in MT nucleation. GIT1 is phosphorylated on tyrosine and associates with γ-tubulin in a Ca2+ -dependent manner. Our data suggested a novel signaling pathway for MT rearrangement in mast cells where tyrosine kinase-activated GIT1 and βPIX work in concert with Ca2+ signaling to regulate MT nucleation. We tested the capability of GIT1 and PIX to influence -tubulin function in more cell types. We found out that GIT1/βPIX signaling proteins together...
