Análise e Acompanhamento da Execução de Soluções de Melhoria de Conforto Térmico na Reabilitação de Edifícios

O presente relatório inserido na Unidade Curricular de DIPRE do Mestrado em Engenharia Civil – Ramo de Construções, do Instituto Superior de Engenharia do Porto e desenvolvido no âmbito do estágio curricular realizado na empresa Porto Vivo, SRU, tem como objetivo descrever as atividades realizadas durante o período de estágio, no Núcleo de Gestão de Obras, tais como o acompanhamento das Operações de Reabilitação e Realojamento no Morro da Sé, participações em reuniões de obra com empreiteiros e projetistas, realização de vistorias para determinar o nível de conservação dos edifícios. Irá ainda ser abordado um caso de estudo relativo ao comportamento térmico da fração autónoma de um edifício em reabilitação, utilizando como base o Regulamento de Desempenho Energético dos Edifícios de Habitação (REH). Por último, as conclusões finais do estágio, a apreciação das atividades desenvolvidas, a sua importância para o estagiário a nível pessoal e profissional e ainda as ilações referentes ao caso de estudo.As part of DIPRE class of Civil Engineering’s – Construction Business - Master Course at Instituto Superior de Engenharia do Porto, the present report was developed under the internship held at Porto Vivo – SRU, it aims to describe the activities performed under the internship period, at Núcleo de Gestão de Obras the tasks of the monitoring of the rehabilitation and resettlement operations of Morro da Sé, participation of site meetings with contractors and designer managers and undertaken of surveys to determine the building’s conservation level. It will also be discussed a study case, related with the thermal behavior of an autonomous fraction from a building undertaking rehabilitation works, based on Regulamento de Desempenho Energético dos Edifícios de Habitação (REH). At last, it will be presented the internship’s final conclusions, the assessments of developed activities and its importance for the trainee at a personal and professional level as well as the conclusions from the study case

Rs1888747 polymorphism in the FRMD3 gene, gene and protein expression: Role in diabetic kidney disease

© 2016 Buffon et al. Background: We carried out a case-control study in patients with type 2 diabetes mellitus (T2DM) to evaluate the association between seven single nucleotide polymorphisms (SNPs) previously described to be linked to diabetic kidney disease (DKD) in type 1 diabetes mellitus (T1DM). Additionally, we evaluated gene and protein expression related to the polymorphism associated with DKD. Methods: The association study included 1098 T2DM patients (718 with DKD and 380 without DKD). Out of the 13 polymorphisms associated with DKD in a previous study with T1DM, seven were chosen for evaluation in this sample: rs1888747, rs9521445, rs39075, rs451041, rs1041466, rs1411766 and rs6492208. The expression study included 91 patients who underwent nephrectomy. Gene expression was assessed by RT-qPCR and protein expression in kidney samples was quantified by western blot and it localization by immunohistochemistry. Results: The C/C genotype of rs1888747 SNP was associated with protection for DKD (OR = 0.6, 95 % CI 0.3-0.9; P = 0.022). None of the other SNPs were associated with DKD. rs1888747 is located near FRMD3 gene. Therefore, FRMD3 gene and protein expression were evaluated in human kidney tissue according to rs1888747 genotypes. Gene and protein expression were similar in subjects homozygous for the C allele and in those carrying the G allele. Conclusions: Replication of the association between rs1888747 SNP and DKD in a different population suggests that this link is not the result of chance. rs1888747 SNP is located at the FRMD3 gene, which is expressed in human kidney. Therefore, this gene is a candidate gene for DKD. However, in this study, no rs1888747 genotype or specific allele effect on gene and/or protein expression of the FRMD3 gene was demonstrated
