Mestrado em FinançasEste estudo contém a avaliação e a respetiva estimativa do valor intrínseco da ação da REN para 04/01/2016. O nosso Relatório de Avaliação é uma continuação do processo de implementação de um novo formato de apresentação para este tipo de projeto, agregando as regras e estilo do Trabalho Final do Programa de Mestrado do ISEG e as recomendações do CFA Institute (Pinto, Henry, Robison, and Stowe, 2010). A escolha da REN provém do meu interesse pessoal no setor energético e do seu complexo sistema, desde da produção ao consumidor final, sendo que a REN encontra-se a meio termo deste trajeto, através do transporte de eletricidade e gás natural. O preço-alvo foi alcançado usando o método mais apropriado em termos de avaliação absoluta, o método dos Fluxos de Caixa Descontados (DCF). Com um preço-alvo de 3.10€ e um potencial de valorização de 9.83% em relação ao preço da ação em 04/01/2016 (2.82€), a recomendação final para a REN é Neutro.This study contains the valuation and the respective estimation of REN´s intrinsic share value for 04/01/2016. Our Equity Research is a continuation of the implementation process of a new presentation format for this kind of project, combining the rules and style of ISEG´s Master Final Project and the CFA Institute (Pinto, Henry, Robison, and Stowe, 2010) recommendations. REN's choice comes from my personal interest in the energy sector and from its complex system, from production to the final consumer, being that REN is in the mid-term of this path, through the transportation of electricity and natural gas. The price target was reached by using the most appropriate method in terms of absolute valuation, the Discounted Cash Flow (DCF) Approach. With a price target of 3.10€ and an upside potential of 9.83% relatively to the share price at 04/01/2016 (2.82€), the final recommendation for REN stands for Neutral.info:eu-repo/semantics/publishedVersio

Interrelationship between potassium rates and the efficiency of Bt genes in the control of Spodoptera frugiperda

O objetivo deste trabalho foi identificar o efeito de doses de potássio sobre a resistência transgênica Bt e os danos causados por Spodoptera frugiperda em plantas de milho, em diferentes estádios de desenvolvimento. O delineamento experimental foi de blocos ao acaso, em arranjo fatorial 3x6, com três doses de potássio (0, 45 e 90 kg ha-1) e seis híbridos de milho (20A55Hx, 30A77PW, AG1051, MG652PW, NS90VTPro2 e NS92VTPro), com três repetições. Os híbridos foram avaliados por meio de análise de variáveis canônicas. Com doses baixas de potássio, a eficácia dos híbridos de milho no controle da lagarta S. frugiperda diminui nos diferentes estádios fenológicos. O uso da tecnologia Bt é mais eficiente quando sob dosagem adequada de potássio de 90 kg ha-1 KCl.The objective of this work was to identify the effect of potassium rates on Bt transgenic resistance and damage caused by Spodoptera frugiperda in corn plants at different developmental stages. The experimental design was a randomized complete block in a 3x6 factorial arrangement, with three potassium rates (0, 45, and 90 kg ha-1) and six corn hybrids (20A55Hx, 30A77PW, AG1051, MG652PW, NS90VTPro2, and NS92VTPro), with three replicates. The hybrids were evaluated through the analysis of canonical variables. With low potassium rates, the effectiveness of the corn hybrids in controlling the S. frugiperda caterpillar decreases in the different phenological stages. The use of the Bt technology is more efficient under an adequate potassium rate of 90 kg ha-1 KCl

Avaliação do potencial carcinogênico do adesivo dentário em um modelo experimental de Drosophilas melanogaster

Adhesive Dentistry was created with the aim of minimizing infiltrations, displacements and unnecessary tooth wear. Currently, much is known about the physical and chemical properties of adhesive systems, but more studies are still needed regarding their properties and biological effects. Dental adhesives have two components that deserve attention, BIS-GMA and bisphenol A (PMA), due to their harmful potential already reported in the literature. Thus, the present study aimed to evaluate the carcinogenic potential of dental adhesive using Drosophilas Melanogaster as an experimental model from the ETT (Epithelial Tumor Test). Drosophilas melanogaster were exposed to six different concentrations of AdperMR Single Bond 2 adhesive (3M do Brasil – Sumaré – São Paulo), namely: 1:20, 1:40, 1:80, 1:160, 1:320 and 1:640 using reverse osmosis water as solvent, in addition to the positive control with Doxorubicin Hydrochloride (DXR) and the negative control with reverse osmosis water. A comparison of the results obtained with the control groups was performed and it was possible to observe that there is a decrease in carcinogenic activity as there is an increase in the dilutions of the patch. However, more research is needed to affirm its carcinogenicity.  A Odontologia Adesiva surgiu com o intuito de minimizar infiltrações, deslocamentos e desgastes dentários desnecessários. Atualmente muito se sabe sobre propriedades físicas e químicas dos sistemas adesivos, porém ainda são necessários mais estudos a respeito de suas propriedades e efeitos biológicos. Os adesivos dentários possuem dois componentes que merecem atenção, o BIS-GMA e o bisfenol A (PMA), devido ao potencial danoso que possuem já relatado na literatura. Dessa forma, o presente estudo objetivou avaliar o potencial carcinogênico do adesivo dentário, utilizando como modelo experimental Drosophilas Melanogaster a partir do ETT (Epithelial Tumor Test). As Drosophilas melanogaster foram expostas à seis diferentes concentrações do adesivo AdperMR Single Bond 2 (3M do Brasil – Sumaré – São Paulo), sendo elas: 1:20, 1:40, 1:80, 1:160, 1:320 e 1:640, utilizando como solvente água de osmose reversa, além do controle positivo com Cloridrato de Doxorrubicina (DXR) e do controle negativo com água de osmose reversa. Foi realizada comparação dos resultados obtidos com os grupos controles e foi possível observar que existe uma diminuição da atividade carcinogênica a medida que há um aumento das diluições do adesivo. No entanto, mais pesquisas são necessárias para afirmar sua carcinogenicidade. &nbsp

CASE REPORT: CENTRAL PRECOCIOUS PUBERTY IN A CHILD WITH BLOCH-SULZBERGER SYNDROME.

Objective: To describe a case of a child with IncontinentiaPigmenti associated with precocious puberty. Case description: a 1 year 7 months old female babywas taken by her parents to a medical appointment because of an aggravation of skin spots with a latté color disseminated throughout the body, which appeared when the child was five months old. The mother also referred premature thelarche and premature pubarche since the child was three months old. Comments: Precocious puberty is defined as the development of secondary sexual characteristics before the age of eightin girls and nine in boys. The Bloch-Sulzberger syndrome, or Incontinentia Pigmenti, is a disorder linked to the X chromosome that affects the skin, eyes, teeth and may be associated with neurological deficits. As much as this specific syndrome involves multiple organs and systems, there was no association with an endocrine disorder.    

The essential neurological examination in telemedicine consultations in the context of COVID 19/ O exame neurológico essencial nas consultas de telemedicina no contexto da COVID 19

Introduction: In clinical evaluation, the neurological area is one of the most complex and extensive to be analyzed, besides that, when added with Neurophobia it becomes even more difficult. With the COVID-19 Pandemic, there was an accelerated process of migration from outpatient clinics to digital platforms, requiring doctors to update their way of examining patients. The essential neurological examination, the tool that collaborates in this updated assessment, demonstrates greater objectivity in confirming the normality of the neurological system. The practice of checklists is a tool that helps these doctors to better evaluate their patients, optimizing their time and exams, contributing to its clinical diagnosis. Methodology: Review study integrative process that culminated in the elaboration and adaptation of new measures for essential neurological therapy in patients in the context of COVID-19 through Telemedicine. Results and Discussion: When comparing the essential neurological exam with the knowledge experienced by the authors of this article and the global pandemic context, were recommendations on the application of telemedicine were made. In addition to the need for doctor-patient communication to be audible and visible, without external interference so as not to impair the exams, the participation of a patient's companion is important to assist the doctor in exams. With that done, we identified that some of the exams essential neurological conditions become difficult to perform digitally, being: Indirect fundoscopy and reflexes (Biceps, Brachioradialis, Triceps, Patellar, Aquileu). However, exams such as direct fundoscopy, pupillary reflex, eye chase, mimic facial, gait, and plantar reflex can be examined via digital platforms as long as always the patient is accompanied. Conclusion: It is concluded that, amid pandemic, essential neurological examination becomes outdated, but useful in several areas, helping the doctor to take more informed measures

Epidemiology of tobacco use and nicotine dependence in truck drivers

OBJECTIVE: To investigate the epidemiology of tobacco use and nicotine dependence in a sample of truck drivers in Brazil. METHODS: Between 2015 and 2016, a cross-sectional study was conducted on 624 truck drivers who operate on the BR-050 highway in Brazil. Participants were interviewed about sociodemographic data, occupational characteristics, mental health, behavioral data, and tobacco use. Then, the Fagerstrom Test for Nicotine Dependence (FTND) was used to verify nicotine dependence in smoking truck drivers. Logistic regression and linear regression were also used to verify factors associated with tobacco use in the previous 30 days and nicotine dependence scores, respectively. RESULTS: The prevalence of tobacco use among truck drivers was 21.1% (n = 132; 95%CI: 18.1–24.5). Of the total number of smokers who responded to the FTND (n = 118; 89.4%), most had high/very high nicotinic dependence (68.6%; 95%CI: 59.8–76.3). Tobacco use was associated with absence of religion (adjusted odds ratio [AOR]: 2.60; 95%CI: 1.35–5.01), employment relationship of the contract (AOR = 1.98; 95%CI: 1.26–3.13); > 12 hours daily working time (AOR = 1.80; 95%CI: 1.09–2.98) and alcohol use in the previous 30 days (AOR = 2.92; 95%CI: 1.86–4.57). Irregular physical activity was associated with higher scores of nicotine dependence (β = 1.87; 95%CI: 0.55–3.19). CONCLUSION: The results showed a high prevalence of tobacco use and high/very high nicotine dependence among the truck drivers
