Caracterização de múltiplos polimorfismos de Pneumocystis Jirovecii por multiplex-PCR/Single base extension

Pneumocystis jirovecii é conhecido por causar infecções específicas no aparelho respiratório de seus hospedeiros, principalmente em doentes imunocomprometidos, manifestando-se por uma pneumonia grave e por vezes fatal, normalmente designada por pneumonia por Pneumocystis. A caracterização da diversidade genética de P. jirovecii tem demonstrado que determinados polimorfismos de base única poderão ser reconhecidos como marcadores moleculares de eleição para o estudo da distribuição geográfica, vias de transmissão, resistência/susceptibilidade a fármacos, factores de virulência e genética populacional de subtipos genéticos. Este estudo teve como objectivo a caracterização de polimorfismos de P. jirovecii, através da metodologia PCR multiplex/Extensão de base única (do inglês single base extension), com a principal finalidade de constatar eventuais associações entre polimorfismos de base única, genótipos multilocus, e dados clínicos e demográficos da infecção. Sessenta e seis espécimes pulmonares, previamente considerados positivos para P. jirovecii, obtidos entre 2001 e 2012, a partir de doentes portugueses imunocomprometidos, foram seleccionados de forma aleatória para este estudo multilocus. PCR multiplex foi utilizada para a amplificação simultânea de três regiões genómicas: subunidade grande do rRNA mitocondrial, superóxido dismutase e dihidropteroato sintetase. Cinco polimorfismos de base única, previamente correlacionados com parâmetros da doença, foram genotipados por extensão de base única: mt85, SOD110, SOD215, DHPS165 e DHPS171. Um total de 330 polimorfismos de base única e 29 genótipos multilocus putativos de P. jirovecii foram identificados e caracterizados nos espécimes pulmonares analisados. Os padrões de distribuição dos polimorfismos foram analisados, sendo considerada a variação temporal e/ou geográfica das suas formas alélicas. Constatou-se grande diversidade genotípica entre os isolados de P. jirovecii que poderá ter influência a nível epidemiológico. Foram observadas associações estatísticas entre mt85/genótipos multilocus e parâmetros demográficos e clínicos. A correlação mais importante verificou-se entre mt85C e cargas parasitárias baixas a moderadas, enquanto mt85T foi associado com cargas parasitárias altas; MLG5, MLG9 e MLG13 foram associados com cargas parasitárias baixas, moderadas e altas, respectivamente. Tais associações demonstram que potenciais marcadores moleculares da infecção por P. jirovecii poderão existir e que polimorfismos/genótipos específicos poderão determinar perfis epidemiológicos da pneumonia por Pneumocystis. A análise genética cruzada permitiu verificar associações entre polimorfismos de base única. Os polimorfismos SOD110T e SOD215C, SOD110C e SOD215T, DHPS165A e DHPS171C, DHPS165G e DHPS171T foram associados estatisticamente. Os genótipos multilocus mais prevalentes foram considerados para o teste recombinatório d1. Dois genótipos multilocus (MLG7 e MLG9) foram observados com elevada frequência, e a análise genética indicou que estes se encontravam sobre-representados na população de P. jirovecii estudada. Estas evidências indicam que o fenómeno de desequilíbrio de ligação e a propagação clonal de subtipos genéticos é frequente, considerando que a espécie P. jirovecii poderá ser representada por uma população com estrutura epidémica. O presente trabalho confirmou a importância do estudo de polimorfismos em P. jirovecii, sugerindo que a caracterização multilocus poderá fornecer informação relevante para a compreensão dos padrões, causas e controlo da infecção, melhorando assim a investigação deste importante patogéneo.

A SDK improvement towards gesture support

Human-Computer Interaction have been one of the main focus of the technological community, specially the Natural User Interfaces (NUI) field of research as, since the launch of the Kinect Sensor, the goal to achieve fully natural interfaces just got a lot closer to reality. Taking advantage of this conditions the following research work proposes to compute the hand skeleton in order to recognize Sign Language Shapes. The proposed solution uses the Kinect Sensor to achieve a good segmentation and image analysis algorithms to extend the skeleton from the extraction of high-level features. In order to recognize complex hand shapes the current research work proposes the redefinition of the hand contour making it immutable to translation, rotation and scaling operations, and a set of tools to achieve a good recognition. The validation of the proposed solution extended the Kinects Software Development Kit to allow the developer to access the new set of inferred points and created a template-matching based platform that uses the contour to define the hand shape, this prototype was tested in a set of predefined conditions and showed to have a good success ration and has proven to be eligible for real-time scenarios.

EDP inovcity pilot study proposal: A set-top box interface

In this work I propose an additional test to be implemented in EDP’s residential electricity use feedback trials, under InovCity’s project scope. The proposed product to be tested consists of an interface between the smart meter and the television, through a set-top box. I provide a theoretical framework of the importance of feedback, an analysis of results from past studies involving smart metering, and a detailed description of my proposal. The results of a self-developed questionnaire related to the proposal and segmentation issues are also analyzed. Finally, general conclusions are drawn and potential future improvements and challenges are presented.

A proposta de regulamento relativo a um direito europeu comum da compra e venda e as suas implicações no direito português

We have witnessed in recent years, an obvious effort by the competent European institutions, towards the harmonization of general law applicable to all Member States (MS's). Many developments have been registered in several areas of law, a europeanization process that aims to add value to cross-border transactions and, consequently, the internal market and european trade. This trend manifests itself in general to the private law level, and particularly in contract law. The extension of the field in which market participants - whether professionals or consumers - can act, must imperatively be articulated with a consequent wider protection. After all, the consumer is also a leading European purposes and its level should not be called into question for the sake of promoting trade. The link between the positions of two opposing parties, professionals and consumers, requires commitment and work reinforced by the institutions but only on that basis is consistent legislative production. The proposed Regulation on a Common European Sales Law of the sale, the European Commission, set focus to European contract law and raises questions about the relevance and necessity of such uniformity. An instrument for purposes of harmonization of European contract law, that can be applied to all cross-border consumer contracts, similar in all MS's certainly bring many benefits. However, its applicability and usefulness would depend on the level of protection that would provide, compared to the existing national rights. Would an optional instrument ensure the designs of a common law? Moreover, would a binding instrument be the best alternative in that sense? Keywords:

Product extension services deployment platform

Due to the progresses made in the branch of embedded technologies, manufacturers are becoming able to pack their shop floor level manufacturing resources with even more complex functionalities. This technological progression is radically changing the way production systems are designed and deployed, as well as, monitored and controlled. The dissemination of smart devices inside production processes confers new visibility on the production system while enabling for a more efficient and effective management of the operations. By turning the current manufacturing resources functionalities into services based on a Service Oriented Architecture (SOA), in order to expose them as a service to the user, the binomial manufacturing resource/service will push the entire manufacturing enterprise visibility to another level while enabling the global optimization of the operations and processes of a production system while, at the same time, supporting its accommodation to the operational spike easily and with reduced impact on production. The present work implements a Cloud Manufacturing infrastructure for achieving the resource/service value-added i.e. to facilitate the creation of services that are the composition of currently available atomic services. In this context, manufacturing resource virtualization (i.e. formalization of resources capabilities into services accessible inside and outside the enterprise) and semantic representation/description are the pillars for achieving resource service composition. In conclusion, the present work aims to act on the manufacturing resource layer where physical resources and shop floor capabilities are going to be provided to the user as a SaaS (Software as a Service) and/or IaaS (Infrastructure as a Service).

Unusual abdominal tumors with intracardiac extension. Two cases with successful surgical resection

Abdominal tumors that can grow through vascular lumen and spread to the right heart are rare. Although these tumors have different histologic aspects, they may cause similar abdominal and cardiac symptoms and are a serious risk factor for pulmonary embolism and sudden death when they reach the right atrium and tricuspid valve. The best treatment is radical surgical resection of the entire tumor using cardiopulmonary bypass with or without deep hypothermia and total circulatory arrest. We report the cases of two patients, the first with leiomyosarcoma of the inferior vena cava and the other with intravenous leiomyomatosis of the uterus that showed intravascular growth up to right atrium and ventricle, who underwent successful radical resection in a one-stage procedure with the use of cardiopulmonary bypass. We discuss the clinical and histologic aspects and imaging diagnosis and review the literature.

O abuso de informação privilegiada (insider trading)

In the stock market, information takes on special relevance, due to the market’s permanent updating and the great fluidity of information existent therein. Just as in any other negotiations, the party with the better information has a bargaining advantage, as it is able to make more advantageous business decisions. However, unlike most other markets, the proper functioning of the stock market is greatly dependent on investors’ trust in the market itself. As such, if there are investors who, due to any condition they possess or office they hold, have access to relevant information which is not accessible to the general public, distrust is bred within the market and, consequently, investment is lessened. Thus, there is a need to prevent those who hold privileged information from using it in abusive ways. In Portugal, abuse of privileged information is set out and punished criminally in Article 378. of the Portuguese Securities Code (‘Código dos Valores Mobiliários’). In this dissertation, I have set out, firstly, to analyze the inherent conditions for there to be a crime of abuse of privileged information; secondly, to analyze two well-known cases, which took place and were decided in other jurisdictions, and attempt to understand how these cases would fall under Article 378. of the Portuguese Securities Code. Whereas the first case, Chiarella v. United States, was scrutinize under Article 378 of the Portuguese Securities Code, in the second, Lafonta v. AMF, the conclusion arrived at was that the crime taken place was different. This analysis allowed, on one hand, the application to a particular case of prerequisites and concepts which were explained, at a first approach, from a more theoretical perspective; on the other hand, it also allowed the further development of specific aspects of the regime, namely the difference between an insider and a tipee, as well as to more clearly set out the limits to the precise character of the information at hand.

Do Comandante Supremo das Forças Armadas

The President of the Portuguese Republic’s relation with the Armed Forces in the current political system is not confined to the vast legislative and constitutional set. As Chief of State and Supreme Commander of the Armed Forces, the President holds different powers. We develop an approach through the main concepts and themes that regulate the Armed Forces and National Defense, focusing the relations that involve the President directly. The attribution by inherence of the Supreme Command of the Armed Forces to the Chief of State, imposes a peculiar relation with the remainder sovereign institutions. The need to analyze the intermediate services as far as military and defense issues are concerned becomes necessary, in particular the role of the Military Cabinet – as a structure of direct support – and the High Council of National Defense – as an advisory body.

How aspiring filmmakers cope with unexpected events on set

Making the transition between plans and unexpected occurrences is something organizations are used to doing every day. However, not much is known about how actors cope with unanticipated events and how they accommodate them within predefined schedules. In this study, we draw on an inductive analysis of aspiring filmmakers’ film sets to elaborate on how they plan their shooting activities every day, only to adjust them when unforeseen complications arise. We discover that film crews anchor their expectations for the day based on a planned shooting schedule, yet they incorporate a built-in assumption that it will inevitably be disrupted. We argue that they resort to triage processes and “troubleshooting protocols” that help decipher incoming problems. Familiar problems are solved by making use of experience obtained from past situations, whereas unprecedented problems are solved through a tacit protocol used as a tool to quickly devise an appropriate game plan. This study contributes to the literature on sense-making and provides valuable information about the unexplored world of filmmaking.

Regret associated with past and future messes under a maximizing mind-set

Promotions can make you happy if you get the “best” deal or miserable if you miss it. Previous research on this topic has shown that people favor products associated with a past miss to products associated with a future miss, and people in a maximizing mind-set, i.e. people who search for the best in different domains, feel more regret in a consumption domain. This research confirms that consumers prefer purchasing a product associated with a past miss (Experiments 1 and 2) and that regret levels are higher when participants come across the future miss, under the maximizing mind-set (Experiment 2). These studies add to the notion that information on regret might prompt people to make decisions towards a more optimistic outcome.

A GIS extension model to calculate urban heat island intensity based on urban geometry

This paper presents a simulation model, which was incorporated into a Geographic Information System (GIS), in order to calculate the maximum intensity of urban heat islands based on urban geometry data. The method-ology of this study stands on a theoretical-numerical basis (Okeâ s model), followed by the study and selection of existing GIS tools, the design of the calculation model, the incorporation of the resulting algorithm into the GIS platform and the application of the tool, developed as exemplification. The developed tool will help researchers to simulate UHI in different urban scenarios.
