A mina do Trimpancho, situada na zona fronteiriça entre Portugal e Espanha, integra este contexto geológico e apresenta vestígios de exploração antiga, com escombreiras remanescentes que constituem fontes de contaminaçã...
Homozygosity for a rare FASTKD2 variant resulting in an adult onset autosomal r...
Gonçalves, Francisco Pereira; Tavares, Isabel; Silva, Roberto; Nunes, Ana Teresa; Pereira, Luciano; Campos, Andreia; Pinto, Joel; Lopes, AnaMitochondrial cytopathies can have kidney involvement in up to half of cases. Their diagnosis is challenging due to phenotypic variability, lack of noninvasive tests to assess mitochondrial dysfunction, and genetic heterogeneity. We report on a young adult male with hypertrophic cardiomyopathy (HCM) and chronic kidney disease (CKD) with subnephrotic proteinuria who presented to the emergency department with kid...
A potencialidade da Geoquímica para o estudo da Paleontologia de Vertebrados.
Silva, Roberto; Balbino, A.; Bruno, Bruno Silva; Costa, Mafalda; Barrulas, Pedro; Ribeiro, C.Neste trabalho, foram estudados dentes de Saurópodes, recolhidos nas formações do Jurássico Superior da Bacia Lusitaniana, tendo-se realizado análise de difração de raios-X,fluorescência de raios-X, SEM-EDS e LA-ICP-MS. Verificou-se que a hidroxilapatite domina a mineralogia dos exemplares e que os dentes são compostos principalmente por Ca e P, em termos de elementos maiores, mas também por Fe, Mg, Mn, Al e K,...

Industrial sustainability of microbial keratinases: production and potential ap...
Menezes, Cíntia Lionela Ambrósio; Santos, Rafaela do Couto; Santos, Marisa Viegas; Boscolo, Maurício; Silva, Roberto; Gomes, EleniKeratinases are proteolytic enzymes with a particular ability to cleave peptide bonds in keratin, and in other proteins. Due to their broad-spectrum of activity, keratinases are considered viable substitutes for chemical and thermal treatments of proteinrich industrial by-products. Among these protein residues, special attention has been given to keratinous materials (feathers, hair, horns, etc.), which disposa...

Filipe, Rita; Caldas, João Paulo; Soares, Neuza; Sabino, Raquel; Veríssimo, Cristina; Silva, Roberto; Silva-Pinto, André; Tavares, MargaridaSchizophyllum commune is a basidiomycetes worldwide distributed that has emerged as cause of invasive infections in immunosuppressed patients. We present a case of a man who was simultaneously diagnosed with a small cell non-Hodgkin lymphoma and a sphenoid sinusitis by S. commune. Intraoperative observation and histology description were crucial to consider an alternative diagnosis to mucormycosis suggested by ...
