Texto completo da fonteThis work presents an inverse problem based method for ultrasound image reconstruction which uses the L2-norm (or euclidean norm) as a penalty for the error between the data and the solution, and the L1-norm as a regularization penalty. The motivation for the use of of L1 regularization is the sparsity promoting property of this type of regularization. The sparsity of L1 regularization circumvents the problem of excess of artifatcts that is observed in other approaches of inverse problem based reconstrucion in ultrasound. Such problem is mainly a consequence of the limitation in the discrete representation of a continuous object in the acquisition model. Due to this limitation, reflecting objects in the imaged area are often localized in positions that do not correspond precisely to one of the positions in the discrete model, therefore generating data that do not correspond to the model data. The formulations of the problem with L2 regularization and with L1 regularization are presented and compared in geometric and Bayesian terms. The optimization algorithm proposed is an implementation of Iteratively Reweighted Least Squares (IRLS) and uses the Conjugate Gradient (CG) method inside each iteration, thus being called IRLS-CG. Simulations with computer phantoms are realized showing that the proposed method allows for the reconstruction of images, without observable artifacts, from data with reflectors located in non-modeled positions. Simulations also show a better spatial resolution in the proposed method when compared to the delay-and-sum (DAS) algorithm. It was also observed better computational performance of CG when compared to the matrix inversion in the iterations of IRLS.

Este estudo apresenta uma compreensão sobre o trabalho e a saúde das mulheres que desempenham a função de limpeza, em uma empresa terceirizada que presta serviços a uma instituição de ensino superior do estado do Rio de Janeiro. Pretendeu-se também conhecer os fatores relacionados à organização do trabalho, que podem reverberar negativamente nas relações de trabalho e nas condições de saúde das trabalhadoras. O estudo ancorou-se nos materiais oriundos da Ergonomia da Atividade, da área da Saúde do Trabalhador e suas interseções com as perspectivas de gênero e na Psicodinâmica do Trabalho. Utilizou-se o questionário INSATS para mapear o ambiente físico do trabalho, fatores de exposição, exigências físicas, ritmo e tempo de trabalho, orientação das tarefas, autonomia, relações de trabalho, reconhecimento e satisfação no trabalho, o que mais causa incômodo no trabalho, o estado de saúde das trabalhadoras e a proteção e riscos do trabalho. O questionário foi aplicado a uma população feminina de 21 trabalhadoras. Os resultados apontam para um trabalho muito assemelhado ao trabalho doméstico, de pouca visibilidade, precarizado, com baixos salários e desvalorizado pela sociedade.
This study provides an understanding of the work and health of women who perform the cleaning function on an outsourced company that provides services to a higher education institution in the state of Rio de Janeiro. It was intended to also know the factors related to work organization, which may reverberate negatively on labor relations and health conditions of workers. The study is anchored in materials derived from the activity of Ergonomics, Occupational Health of the area and its intersections with gender perspectives and work psychodynamics. We used the INSATS questionnaire to map the physical work environment, exposure factors, physical demands, rhythm and tempo of work, guidance tasks, autonomy, labor relations, recognition and job satisfaction, which causes more nuisance at work the health status of the working and protection and labor risks. The questionnaire was administered to a female population of 21 workers. The results point to a much resembled work to domestic work, poor visibility, precarious, low-paid and undervalued by society.

Texto completo da fonteMitochondrial damage is linked to many neurodegenerative deseases, such as Parkinson, Alzheimer and Amyotrophic Lateral Sclerosis. These diseases are linked to changes in the splicing pattern of individual mRNAs. Here, we test the hypothesis that mitochondrial damage modulates alternative splicing, not only of a few mRNAs, but in a general manner. We incubated cultured human neuroblastoma cells with the chemical agent paraquat (a neurotoxin that interferes with mitochondrial function, causing energy deficit and oxidative stress) and analysed the splicing pattern of 13 genes by RT-PCR. For each alternatively spliced mRNA, we observed a dose and time dependent increase of the smaller isoforms. In contrast, splicing of all constitutive exons we monitored did not change after paraquat treatment. In addition, we prove that the modulation of alternative splicing by using different drugs correlates with ATP depletion, not with oxidative stress. Such drastic changes in alternative splicing haven’t been observed in cell lines of non-neuronal origin, suggesting a selective susceptibility of neuronal cells to modulation of splicing. Since a significant percentage of all mammalian mRNAs undergoes alternative splicing, we predict that mitochondrial failure will unbalance a large number of isoform equilibriums, thus permitting an important contribution to neurodegeneration. To identify possible drug targets, we tried to understand which is the signal trasduction trasmitting the mitochondrial damage to the splicing machinery. Two classes of proteins determine splice site selection: the hnRNP and the SR proteins. Both of them are phosphorylated and phosphorylation is important for their activity. We have purified hnRNPs and SR proteins from both paraquat-treated and human neuroblastoma control cells and we have studied them with a sub-proteomic approach. While the maps of paraquat-treated and control hnRNPs do not show up significant modifications, the SR proteins appear hypophosphorylated and downregulated by paraquat treatment. Finally, using different inhibitors involving different pathways in the cell, we demonstrate that calcium has a role in the signal trasduction that we are observing. The obtained data are not yet conclusive, but certainly have shown us a correlation between the neurodegeneration and Alternative Splicing. They have laid down the foundation for understanding the way by which the Alternative Splicing is modulated in neurons depending on external stimuli.

Texto completo da fonteBackground: Diabetes type 1 is one of the most common chronic illness effecting children. Sweden is one of the countries in the world with the highest incident of diabetes type 1. Diabetes type 1 is a disease when self-care plays a life effecting part. As the disease often affects children the parents’ participation in the self-care play a central part. Aim: The aim of this study is to describe parents’ experience of participating in nursing for their child with diabetes type 1. Method: This study is regular literatures study, based on 10 qualitative articles. Results: The result shows that parents’ carried a huge responsibility regarding nursing for the child with diabetes type 1. Parents’ experience regarding participating in nursing for their child consisted in different feelings, thoughts and changes. The result is presented in three categories emotional reactions, nursing affecting the everyday life and a new world. Conclusions: It’s important to highlight parents experience as it can contribute to developing family nursing. Through this the nurse can help the family to achieve a god and safe care for the family having a child with diabetes type 1. The result off this study concludes the important of seeking understanding for the patients’ perspective, by the nurse. Which the author of this study sees, in its context meaning understanding the relationship between children’s disease and parents’ experience. Relevance to clinical practice: Increased knowledge by the nurse in the subject will contribute to better care, where family nursing is in larger computation.

Texto completo da fonteMany applications at millimeter wavelengths require fast electronic phase shifters. In this study, the design of diode-grid phase shifters is presented, the fabrication of diode-grids on monolithic gallium-arsenide substrates is demonstrated, and the measurement of these grids is discussed. A new computer-aided design tool is developed to provide an interactive environment for design and to form a basis for comparing theory and experimental results. Diode-grids have been fabricated on 2 cm by 3 cm gallium-arsenide wafers with 2000 aluminum Schottky diodes. A novel small aperture reflectometer is computerized to use a wave-front division interference technique to measure the reflection coefficient of the grids. A 70° phase shift with a 6.5-dB loss was measured at 93 GHz when the bias on the diode-grid was changed from -3V to +1V.
