Geodesic languages for rational subsets and conjugates in virtually free groups
Carvalho, André; Silva, PedroWe prove that a subset of a virtually free group is rational if and only if the language of geodesic words representing its elements (in any generating set) is rational and that the language of geodesics representing conjugates of elements in a rational subset of a virtually free group is context-free. As a corollary, the doubly generalized conjugacy problem is decidable for rational subsets of finitely generat...
Síndrome Antissintetase: A Síntese de um Caso Complexo
Carvalho, André; Rodrigues, Pedro; Faria, Sara; Miranda, Maria; Isabel Bessa; Gonçalves, AbílioA síndrome antissintetase é uma miopatia inflamatória autoimune definida pela presença de anticorpos antiaminoacil-tRNA sintetases, associada ao desenvolvimento de miosite, doença pulmonar intersticial e/ou artrite. É uma entidade rara, pouco conhecida e subdiagnosticada, com apenas dois casos publicados em Portugal. Relatamos o caso de uma doente de 62 anos, raça negra, internada com um quadro de doença pulmon...
Assessing Tax Policies for Urban Rehabilitation: The Role of Tax Incentives on ...
Carvalho, André; Dinis, Ana; Pereira, LilianaThe urgent need to transform buildings into sustainable energy-efficient spaces is driven by the environmental impact of construction activities. This study examine the impact of tax incentives on urban rehabilitation among Portuguese companies using data from the Portuguese Tax Authority Portal (2015-2022) and the Sabi Database. Employing SPSS for descriptive analysis and Pearson correlation, the authors exami...
Multifunctional magneto-plasmonic lipogel based on peptide hydrogel for applica...
Gomes, Valéria; Veloso, Sérgio R. S.; Carvalho, André; Hilliou, L.; Coutinho, Paulo J. G.; Moura, C.; Martins, J. A. R.; Castanheira, Elisabete M. S.Supramolecular hydrogels, particularly low-molecular-weight peptide hydrogels, are promising drug delivery systems due to their ability to change the solubility, targeting, metabolism and toxicity of drugs. Magneto-plasmonic liposomes, in addition to being remotely controllable with the application of an external magnetic field, also increase the efficiency of encapsulated drug release through thermal stimulati...
Decoding host-environment interactions in progressive pulmonary fibrosis: insig...
Meneses, Alexandra; Cardoso, Catarina G.; Coelho, David B.; Melo, Natália; Mota, Patrícia C.; Guimarães, Susana; Moura, Conceição S.; Carvalho, AndréInterstitial lung diseases (ILDs) comprise a heterogeneous group of parenchymal lung disorders characterized by diffuse infiltration of immune effector cells, fibroblasts, myofibroblasts, and extracellular matrix deposition at various pulmonary compartments. These conditions can progress to end-stage fibrosis, respiratory failure, and eventually, death. In 2020, we initiated the first national ILD registry and ...
Effectiveness of relaxation and hypnosis interventions in distressed patients w...
Pereira, M. Graça; Vilaça, Margarida; Pedras, Susana; Carvalho, André; Vedhara, Kavita; Dantas, M. Jesus; Lopes, Alberto; Faria, SusanaDiabetic foot ulcer (DFU) healing is a complex and slow process that depends on several factors such as the patient's physical health. However, psychological factors such as distress, which are commonly reported by patients with DFU, may also influence DFU development and recurrence. This pilot randomised control trial (RCT) assesses the effectiveness of progressive muscle relaxation and hypnosis on DFU healing...

Martins, Adriana; Monteiro, Ana; Carvalho, André; Melo, Bruna Beppler; Siqueira, Carolina Gavron; Teixeira, Diogo; Gomes, Edson; Nunes, Fábio(Excerto Prefácio)Os trabalhos aqui compilados têm origem nos relatórios apresentados pelos autores — enquanto estudantes— na unidade curricular de Projeto Integrador, da quarta edição do Curso de Pós-Graduação “Coordenação BIM” (Building Information Modelling) promovido pelo ISEP (Instituto Superior de Engenharia do Porto), pela ESAP (Escola Superior Artística do Porto) e pela BIM Academy de Barcelona, em 2023...
New supramolecular hydrogels based on diastereomeric dehydrotripeptide mixtures...
Oliveira, Carlos B. P.; Carvalho, André; Pereira, Renato B.; Pereira, David M.; Hilliou, L.; Jervis, Peter J.; Martins, J. A. R.; Ferreira, Paula M. T.Self-assembly of peptide building blocks offers unique opportunities for bottom-up preparation of exquisite nanostructures, nanoarchitectures, and nanostructured bulk materials, namely hydrogels. In this work we describe the synthesis, characterization, gelation, and rheological properties of new dehydrotripeptides, Cbz-L-Lys(Cbz)-L,D-Asp-∆Phe-OH and (2-Naph)-L-Lys(2-Naph)-L,D-Asp-∆Phe-OH, containing a N-termin...
Relaxation intervention to improve diabetic foot ulcer healing: protocol for a ...
Ferreira, Gabriela; Carvalho, André; Pereira, M. GraçaObjective: A mixed-methods approach nested in a pilot three-arm randomised controlled trial (RCT) was conducted to evaluate the feasibility and acceptability of an intervention of progressive muscle relaxation with guided imagery (experimental group) compared to a neutral guided imagery placebo (active control group) and a group that did not receive any psychological intervention (passive control group). The pu...
A Política Fiscal à Proteção Florestal no Contexto das Sociedades Portuguesas
Dinis, Ana; Carvalho, André; Pereira, LilianaThis article aims to study the fiscal incentives for forest protection in Portugal. Understanding the reality of this fiscal policy is fundamental in the context of sustainable forest management. After reviewing the literature focused on the importance of the forest as an essential asset to meet human needs, the Portuguese tax regime in this area is analysed. This is followed by a study of tax incentives for Fo...
