Cima, Joana Daniela Ferreira; Paschoalotto, Marco Antonio Catussi; Costa, Hélder; Fernandes, BrunoThis study investigates the sentiment analysis of tweets from the four most influential presidential candidates in the 2022 Brazilian elections. Tweets from July 1 to October 30 were gathered using a custom Python script, and the sentiments expressed in these tweets were analyzed with the VADER sentiment analysis library. Two econometric models were estimated to study temporal shifts in sentiment and the effect...

Fernandes, BrunoUm dos temas mais debatidos em Economia Política é o impacto da economia na popularidade dos líderes políticos. É amplamente aceite que esta tem impacto na popularidade, no entanto, a investigação tem produzido resultados instáveis e, por vezes, contraditórios. Os três primeiros ensaios desta dissertação procuram dar foco a potenciais causas deste problema. O primeiro ensaio estuda a diferença entre a economia ...
Diagnosis and Laboratory Follow-Up of Patients with Multiple Myeloma: Guideline...
Pires, Ana Marta; Barreto, João Pedro; Caetano, Joana; Soares, Maria José; Geraldes, Catarina; Fernandes, Bruno; Coucelo, Margarida; Chacim, SérgioMultiple myeloma is a neoplasm of plasma cells that in most cases is associated with the secretion of monoclonal immunoglobulins and can involve multiple organs. Its timely diagnosis is essential to limit or avoid irreversible damage and dysfunction of target organs. Appropriate initial stratification of patients allows for optimization in the selection and sequence of therapy, as well as proper follow-up durin...

Changing human hair fibre colour and shape from the follicle
Matamá, Maria Teresa Gonçalves Macedo; Costa, Cristiana Filipa Chaves; Fernandes, Bruno; Araújo, Rita; Cruz, Célia F.; Tortosa, FranciscoIntroduction: Natural hair curvature and colour are genetically determined human traits, that we inten tionally change by applying thermal and chemical treatments to the fibre. Presently, those cosmetic methodologies act externally and their recurrent use is quite detrimental to hair fibre quality and even to our health. Objectives: This work represents a disruptive concept to modify natural hair colour and cur...
Economic forecasts and executive approval
Aguiar-Conraria, Luis; Fernandes, Bruno; Magalhães, Pedro C.This research note investigates how different sources of economic information affected citizens’ approval of the government in Portugal from 2001 to 2018. It compares the predictive power of the revised and most accurate data on GDP growth with other economic indicators that were available to the public at the time, such as the first estimates of recent growth and the forecasts of future growth. It finds that a...
A review of computational modeling in wastewater treatment processes
Duarte, Maria Salomé; Martins, Gilberto; Oliveira, Pedro; Fernandes, Bruno; Ferreira, Eugénio C.; Alves, M. M.; Lopes, Frederico; Pereira, M. A.Wastewater treatment companies are facing several challenges related to the optimization of energy efficiency, meeting more restricted water quality standards, and resource recovery potential. Over the past decades, computational models have gained recognition as effective tools for addressing some of these challenges, contributing to the economic and operational efficiencies of wastewater treatment plants (WWT...

The Economy and Executive Approval in a Semi-Presidential Regime
Aguiar-Conraria, Luis; Fernandes, Bruno; Magalhães, Pedro C.Over the last two decades, several studies have enhanced our understanding of the relationship between the economy and public support for the executive in Portugal (Veiga, 1998; Veiga and Veiga, 2004a; 2007). The central finding is clear: the public approval of governments and prime ministers is affected by economic performance. This is not at all surprising. Left-right socio-economic issues have dominated the ...
Profiling microglia in a mouse model of Machado–Joseph disease
Campos, Ana Bela; Silva, Sara Duarte; Fernandes, Bruno; Neves, Sofia Pereira das; Marques, Fernanda; Castro, Andreia Teixeira; Carvalho, Andreia NevesMicroglia have been increasingly implicated in neurodegenerative diseases (NDs), and specific disease associated microglia (DAM) profiles have been defined for several of these NDs. Yet, the microglial profile in Machado–Joseph disease (MJD) remains unexplored. Here, we characterized the profile of microglia in the CMVMJD135 mouse model of MJD. This characterization was performed using primary microglial cultur...
