Exploring canine mast cell tumors : an investigation into demographic character...
Catarino, J.; Pinello, K.; Niza-Ribeiro, J.; Santos, J.; Payan-Carreira, R.; Reis, Joana; Faísca, P.Mast cell tumors (MCT) are among the most common neoplasia in dogs, representing up to 21 % of skin tumors. However, etiology and risk factors for its development remain unclear. This study aimed to reduce this knowledge gap by comprehensively analyzing 905 MCT cases diagnosed in Portugal between 2019 and 2021, using descriptive and inferential analyses. Most tumors affected the skin, with 69.9 % and 21.2 % cla...
Rational Approach to Design Gold Nanoparticles for Photothermal Therapy: the ef...
Ferreira-Gonçalves, T.; Nunes, D.; Fortunato, E.; Martins, R.; de Almeida, A.P.; Carvalho, L.; Ferreira, D.; Catarino, J.; Faísca, P.; Ferreira, H.A.Among the unique characteristics associated to gold nanoparticles (AuNPs) in biomedicine, their ability to convert light energy into heat opens ventures for improved cancer therapeutic options, such as photothermal therapy (PTT). PTT relies on the local hyperthermia of tumor cells upon irradiation with light beams, and the association of AuNPs with radiation within the near infrared (NIR) range constitutes an a...
Evaluation of inflammatory infiltrates in the endometrium of the jenny (Equus a...
Radar-Chafifirovitch, R.; Catarino, J.; Lourenço, L.; Payan-Carreira, R.; Ferreira-Dias, G; Miró, J.; Quaresma, M.; Pires, M.AIntroduction: Endometrial immune cell infiltration and its biological significance has not yet been investigated in the jenny. In other species, resident immune cells contribute to homoeostasis and female fertility. However, chronic inflammation leads to endometrosis, a major cause of subfertility and infertility in mares, represented by irreversible and progressive fibrosis, glandular and vascular changes. So ...
ENDOVASCULAR REPAIR OF THORACOABDOMINAL AND PARA-RENAL AORTIC ANEURYSMS WITH FE...
Quintas, A.; Albuquerque e Castro, J.; Aragão Morais, J.; Bastos Gonçalves, F.; Ferreira, R.; Vasconcelos, L.; Alves, G.; Abreu, R.; Camacho, N.Introdution: Aneurismal disease involving the thoracoabdominal segment adds significant complexity to endovascular aortic repair. Objective: Evaluate institutional experience of a tertiary center in fenestrated and branched aneurysm repair for throracoabdominal or juxtarenal aortic aneurysms Methods: Retrospective analysis of a consecutive series of patients treated by endovascular repair using fenestrate...
ILIAC BRANCH DEVICES TO PRESERVE INTERNAL ILIAC ARTERY IN ANEURISMATIC DISEASE
Quintas, A.; Albuquerque e Castro, J.; Aragão Morais, J.; Bastos Gonçalves, F.; Vasconcelos, L.; Alves, G.; Ferreira, R.; Abreu, R.; Camanho, N.Introdution: Aneurismal disease of the iliac arteries is present in 11 to 43% of abdominal aortic aneurysms. Iliac branched devices (IBDs) enable the preservation of internal iliac arteries minimizing the risk for complications related to its intentional occlusion. Methods: Retrospective analysis of a consecutive series of patients selected for the endovascular repair of aneurysmatic disease using IBD...
Compatibility assessment of commercial cements and superplasticizers
Custódio, J.; Coelho, S.; Catarino, J.; Vieira, M.; Ribeiro, A. C.In spite of the widespread use of superplasticizers, it is still not possible to anticipate the compatibility between these materials and a specific cement. Such lack of knowledge does not restrain the use of admixtures in concrete, but it makes it harder to optimise mixtures and can lead to an unexpected behaviour. Therefore, in order to contribute to the on-going discussion concerning the cement-superplastici...
Identificação de parâmetros que influenciam a compatibilidade cimento-adjuvante
Custódio, J.; Coelho, S.; Catarino, J.; Vieira, M.; Ribeiro, A. C.Neste estudo foi avaliada a compatibilidade entre três cimentos e cinco adjuvantes, todos produtos comerciais. Os cimentos e os adjuvantes foram selecionados por apresentarem características químicas e físicas distintas para que a avaliação das pastas, com eles produzidas, permitisse determinar quais as propriedades que mais influenciam a compatibilidade entre ambos. Os resultados permitiram identificar alguns ...

Caracterização de sais solúveis em amostras de Granito da Sé do Porto
Esteves, A.; Catarino, J.Na continuação dos estudos que o Núcleo de Materiais Pétreos e Cerâmicos do Departamento de Materiais tem vindo a realizar na Sé do Porto, foram recolhidas por aquele Núcleo oito amostras de granito na fachada da Sé para identificação e quantificação dos sais solúveis em água. Neste relatório apresentam-se os resultados obtidos na identificação e quantificação dos aniões e catiões presentes nos extractos aquoso...
Mortars and their compatibility for the conservation of masonry walls in Tróia ...
Delgado Rodrigues, J.; Esteves, A.; Catarino, J.Due to a very long exposure since the first excavations, the Tróia archaeological site shows conservation problems of different types and grades. Most of them are directly connected to the geographical location facing the sea and also reflect the lack of due conservation care. Four mortar typologies were studied in the laboratory and were subsequently applied in limited areas of the archaeological site as testi...
