Relatório de estágio curricular no Ministério Público na Comarca de Setúbal

This report represents four months of study on activities in the public prosecution service at the Local Instance of Setúbal judiciary district, started in September 2014 and completed of the same year. This report was prepared considering all the teachings of criminal law courses and criminal procedural law, doctrine, jurisprudence and all the practical experience experienced with prosecutors. In this context, their traineeship provided contact with different procedural stages: the investigation stage that allowed to understand better the progress of the processing of summary proceedings; the expedient distribution of urgent cases; the investigation stage, as regards the procedural impulse assistant and the accused; and the trial stage. This last phase allowed contact with different types of crimes especially road crimes and the crime of domestic violence. The analysis carried out the summary proceedings in the Public Ministry service would acquire relevant information to explain the incidence of road crimes. Topics will be addressed that were found on stage during the various procedural stages, as the implementation of new judicial map. The relationship between the prosecution and the Criminal Police Bodies was also an issue to be addressed. The work also raises awareness of the issue of archives in order to find out the position of assistant.

Effects of an oral vasopressin receptor antagonist (OPC-31260) in a dog with syndrome of inappropriate secretion of antidiuretic hormone

Objective The syndrome of inappropriate secretion of antidiuretic hormone is a rare disorder in dogs characterised by hypo-osmolality and persistent arginine vasopressin production in the absence of hypovolaemia and/or hypotension. The study describes the efficacy and safety of the nonpeptide selective arginine vasopressin V-2 receptor antagonist OPC-31260 in a dog with the naturally occurring syndrome. Design The detailed case history of a dog with spontaneous syndrome of inappropriate secretion of antidiuretic hormone that received long-term therapy with oral OPC-31260 is presented. Effects of the first dose of OPC-31260 and of a dose administered after a continuous dosing period of 12 days are reported. Procedure Packed cell volume, plasma sodium, total protein, arginine vasopressin, renin activity, atrial natriuretic peptide, urine specific gravity, urine output, heart rate and body weight were monitored for 2 h before, and for 4 h after, the first dose of OPC-31260. The same parameters plus plasma osmolality and urine osmolality were monitored when an identical dose was administered after 12 days of therapy. Results Oral administration of OPC-31260 at 3 mg/kg body weight resulted in marked aquaresis with increased urine output and decline in urine specific gravity within 1 h. Corresponding increases in concentrations of plasma sodium, plasma osmolality and plasma renin activity were recorded over a 4 h period. Arginine vasopressin concentration remained inappropriately elevated throughout the study. Results were similar when the trial procedure was repeated after a stabilisation period of 12 days. Long-term therapy with OPC-31260 at a dose of 3 mg/kg body weight orally every 12 h resulted in good control of clinical signs with no deleterious effects detected during a 3-year follow-up period. Despite sustained clinical benefits observed in this case, plasma sodium did not normalise with continued administration of the drug. Conclusions Treatment of a dog with naturally occurring syndrome of inappropriate secretion of antidiuretic hormone with OPC-31260 at 3 mg/kg body weight orally every 12 h resulted in marked aquaresis and significant palliation of clinical signs with no discernible side-effects detected over a 3-year period. Thus, OPC-31260 appears to offer a feasible medical alternative to water restriction for treatment of dogs with syndrome of inappropriate secretion of antidiuretic hormone. Higher doses of OPC-31260 may be required to achieve and maintain normal plasma sodium in dogs with this syndrome.

Pore structure characterisation of pillared clays using a modified MP method

The data of nitrogen adsorption on pillared clays (PILC) are converted to comparison plots (t-plots) to derive their pore size distribution (PSD). As in the MP method, the surface area of a group of pores having similar pore sizes is calculated from the slopes of tangent lines at two succeeding points on a comparison plot. By the modified MP method in this work, the tangent line is extrapolated to the adsorption axis on the t-plot, and the difference between intercepts is used to obtain the volume of the group of pores. From the information of surface area and pore volume, the average width of the pore group can be calculated and hence the PSDs of PILCs are obtained by carrying out such calculation procedures from high to low t. With this method, PSDs of several pillared clays are calculated over a wide pore size range, from micropores to mesopores. It is found that the modified MP method could result in the underestimation of the width of ultramicropores due to the enhancement in adsorption energy in these pores. Nevertheless, the method can be very useful in calculating the surface area and pore volume, as well as a mean width of these pores. For super-micropores and mesopores, pore size can also be underestimated, due to deviation of the pore shape from a slit. The principles of the improved MP method, as well as problems associated with it are thoroughly discussed in this paper. In general, this modified method provides practically meaningful results which are consistent with the pore dimension obtained from powder X-ray diffraction measurements, but involves no complicated theoretical treatment or assumptions.

188Re-PEI-MP as potential agent for metabolic radiotherapy

Introduction: 188Re is a promising radionuclide for metabolic therapy because of the emission of high energy beta-particles. The development of watersoluble bone-seeking polymers such as PEI-MP (polyethyleneimine, functionalised with methylphosphonate-groups) that might be labeled with 188Re are recent approaches, with a strong potential for bone cancer treatment. The aim of this study was to evaluate the efficacy of 188Re-PEI-MP, as therapeutic agent for osteosarcoma, through in vitro and in vivo models.

Sistemas de supervisão e controlo de autómatos: soluções baseadas em OPC E IEC 60870-5-104

Atualmente, no segmento metro-ferroviário, há uma tendência para que todos os equipamentos que constituem os sistemas auxiliares de uma estação (escadas mecânicas, elevadores, bloqueadores, validadores de bilhética, ventiladores, bombas, entre outros) sejam dotados de inteligência. Tipicamente, um conjunto de equipamentos são ligados a um autómato que permite o controlo local e remoto e é vulgar que, sendo de fabricantes diferentes, suportem tecnologias distintas. Um sistema de supervisão que permita o acesso à informação disponibilizada por cada um dos autómatos, ou à atuação sobre um deles, terá por isso que implementar e suportar diversos protocolos de comunicação de forma a não ficar limitado a um tipo de tecnologia. De forma a diminuir os custos de desenvolvimento e operação de um sistema de supervisão e controlo e facilitar a integração de novos equipamentos, com diferentes características, têm sido procuradas soluções que garantam uma mais fácil comunicação entre os diversos módulos intervenientes. Nesta dissertação são implementadas soluções baseadas em clientes OPC-DA e OPC-AE e no protocolo IEC 60870-5-104, permitindo que os sistemas de supervisão e de controlo comuniquem com os equipamentos através destes três módulos. Os principais aspectos inovadores estão associados à implementação de uma arquitetura multiprotocolo usando as novas tendências de supervisão e controlo baseadas em soluções distribuídas.
