Detecção da proteína PLP2 em glioblastomas. / Detection of PLP2 protein in glioblastomas.

Portes Junior, Jose Antonio 28 April 2010 (has links)
Recentemente, com o intuito de identificar genes associados com invasão e proliferação tumoral, identificamos por PCR em tempo real, um aumento de aproximadamente cem vezes da proteína PLP2 em glioblastomas em relação a tecidos normais. Até o momento não há nenhum relato da identificação desta proteína em astrocitomas. Portanto, neste trabalho clonamos e expressamos em bactérias, as alças externas da PLP2 em fusão com a proteína SUMO, com o objetivo de obtermos anticorpos policlonais para serem usados na identificação da PLP2 em tumor humano por western blotting. Realizamos também a expressão da PLP2 fusionada com a EGFP em células de mamífero, para estudar sua distribuição celular, observamos que a PLP2 se concentra em toda a membrana celular e estudos sobre o transito da PLP2 nas células, indicam que ela possa estar envolvida em processos quimiotáticos via CCR1 sugerindo o envolvimento da PLP2 de alguma forma no processo tumorigênico. / Recently, in order to identify genes associated with tumoral invasion and proliferation, identified by real time PCR, an increase of about one hundred times of PLP2 protein in glioblastomas when compared to normal tissue. So far, there is no report of identification of this protein in astrocytomas. Therefore in this study, we cloned and expressed in bacteria the external handles of PLP2 fused with SUMO protein in order to obtain polyclonal antibodies for use in identifying the PLP2 in human tumor by western blotting. We also expressing the PLP2 fused with EGFP in mammalian cells to study its cellular distribution, we observed that focuses PLP2 across the cell membrane and studies on the traffic of PLP2 cells, indicate that it may be involved in chemotactic processes via CCR1 suggesting the involvement of PLP2 somehow in the tumorigenic process.

Vliv pulzního nabíjení na vlastnosti olověných akumulátorů / Influence of the pulse charge on properties of the lead acid batteries

Zbožínek, Štěpán January 2013 (has links)
The presented master´s thesis deals with lead-acid batteries and methods of their charging. First part shortly describes the problems of lead-acid batteries. There are introduced common principles, type of construction and requirements, that should be complied with lead-acid batteries. Following part discusses the basic characteristics of charging. There is given a detailed description of current pulse charging method, on which is also mainly focused this master´s thesis. For this charging method, several basic experiments were done in order to verify functionality of the measuring device, software, the tested cells and primarily to verify charging modes. The goal of this thesis is to find out suitable mode of pulse charging, which would be fast as well as tested cells-friendly. The conclusion of this master´s thesis contains a resume of acquired theoretical knowledge and an evaluation of measured results, on which was the appropriate charging mode proposed.
