A Reversible Event Leading to Lifestyle Reversion: About a Case of PRES
Pereira, Sofia; Almeida, Ana Catarina; Mateus, Hélia; André, RuiThe posterior reversible encephalopathy syndrome (PRES) is a heterogeneous clinical-radiological characterized by a combination of encephalopathy, altered mental status, epileptic seizures, visual disturbances, headache, and focal neurologic signs. Other neurologic deficits, such as ataxia, may occur. PRES can be found in a nonposterior distribution, mainly in watershed areas, including the frontal, inferior te...
Central and peripheral involvement of the retina in the initial stages of diabe...
Santos, Ana Rita; Almeida, Ana Catarina; Rocha, Ana Cláudia; Reste-Ferreira, Débora; Marques, Inês Pereira; Martinho, António Cunha-Vaz; Mendes, LuísTo determine the degree of central microvascular closure using optical coherence tomography angiography in eyes of patients with type 2 diabetes with visible lesions only in the central retina or only in the periphery. Cross-sectional study. All 127 eyes underwent ultra-widefield fundus photography 200° examinations with OPTOS California (Optos, Dunfermline, United Kingdom) and Cirrus Angioplex optical coherenc...
Retinal capillary nonperfusion in preclinical diabetic retinopathy
Santos, Torcato; Santos, Ana Rita; Almeida, Ana Catarina; Rocha, Ana Cláudia; Reste-Ferreira, Débora; Marques, Inês Pereira; Martinho, António Cunha-VazThe aim of the study was to identify retinal microvascular changes using optical coherence tomography angiography (OCTA) in type 2 diabetes (T2D) patients with preclinical retinopathy identified by ultra-widefield fundus photography (UWF-FP). This is a cross-sectional observational study. All patients underwent UWF-FP 200° examinations with OPTOS California (Optos, Dunfermline, UK) and Cirrus AngioPlex® spectra...
Screening for retinopathy of prematury: how can we do better?
Almeida, Ana CatarinaRetinopathy of prematurity (ROP) is a disease of the retina associated with preterm birth, particularly very low birth weight/very preterm infants, in which retinal blood vessels fail to grow and develop normally. In spite of major advances in the understanding of postnatal risk factors for the development of ROP, it continues to be one of the leading causes of childhood blindness in high-income countries. With...
Candida Extracellular Nucleotide Metabolism Promotes Neutrophils Extracellular ...
Afonso, Mariana; Mestre, Ana Rita; Silva, Guilherme; Almeida, Ana Catarina; Cunha, Rodrigo A.; Meyer-Fernandes, José Roberto; Gonçalves, TeresaHost innate immunity is fundamental to the resistance against Candida albicans and Candida glabrata infection, two of the most important agents contributing to human fungal infections. Phagocytic cells, such as neutrophils, constitute the first line of host defense mechanisms, and the release of neutrophil extracellular traps (NETs) represent an important strategy to immobilize and to kill invading microorganis...
Bioactive and adhesive properties of multilayered coatings based on catechol-fu...
Almeida, Ana Catarina; Vale, A. Catarina; Reis, R. L.; Alves, N. M.Chitosan and hyaluronic acid are themost attractive natural polysaccharides used for tissue regeneration, herein innovative orthopedic coatings were constructed by dip-coating technique. Inspired by the tough nacre-like structure, multifunctional (MF) films were constructed using bioactive glass nanoparticles (BGNPs) as the inorganic phase and hyaluronic acid (HA) and chitosan (CHT) polymers as the organic phas...

Efficiency of 2-phenoxyethanol and Clove Oil for Reducing Handling Stress in Re...
Barata, Marisa; Soares, Florbela; Almeida, Ana Catarina; Pousão-Ferreira, Pedro; Ribeiro, Laura; Aragão, CláudiaThe effect of two anesthetics, 2-phenoxyethanol (2-PE) and clove oil (COil) were studied in meagre, Argyrosomus regius. This study aimed to determine the adequate dose of anesthesia for different aquaculture procedures, to assess a sedative or stressor effect of low anesthetic concentrations, and to assess the effect of low anesthetic doses at high fish densities for longer periods of time on fish survival and ...
Chorioretinal atrophy in a patient with Buerger's disease
Marques, André Salgado; Portelinha, Joana; Almeida, Ana Catarina; Guedes, MartaRESUMO A doença de Buerger é uma vasculopatia inflamatória oclusiva que afecta os vasos de pequeno e médio calibre, sobretudo arteriais, das extremidades e que está associada ao tabagismo. O envolvimento visceral é pouco frequente e as complicações oculares são ainda mais raras, eventualmente caracterizadas por oclusões vasculares retinianas. Reportamos o caso de um doente com doença de Buerger com diversas com...
Interspecific variability of endocrine disruption and oxidative stress in two b...
Pereira, Catarina; Gomes, Tânia; Cardoso, Catia; Almeida, Ana Catarina; Araújo, Olinda; Bebianno, Maria João; Cravo, AlexandraEstuaries are highly productive ecosystems that have been increasingly affected by anthropogenic activities. In this study, the presence of endocrine disrupting compounds (EDCs) and their relation to oxidative stress were assessed in two bivalve species (mussels Mytilus galloprovincialis and clams Ruditapes decussatus) from the Ria Formosa Lagoon (south Portugal). We applied the alkali-labile phosphate (ALP) as...
