A paradise for Maldane sarsi antarctica: preliminary characterization of the ma...
Bascur, Miguel; Prófumo, Andrea; Gonzalez-Pineda, Mariona; Monràs-Riera, Pere; Azcárate-García, Tomás; Aubach-Masip, Àlex; Llobet, Marina DeSoft-bottom areas are among the least explored ecosystems in Antarctica. To improve our understanding of these environments, we performed a preliminary assessment of the marine macrobenthic fauna in False Bay, Livingston Island, near Huntress Glacier (South Shetland Islands, Antarctica). Fourteen Van Veen grabs (0.018 m(2) area) were deployed at two stations within the bay at depths of 174-210 m. The samples pr...
Plasma Metabolites Associated with OCT Features of Age-Related Macular Degenera...
Laíns, Inês; Han, Xikun; Gil, João; Providência, Joana; Nigalye, Archana; Alvarez, Rodrigo; Douglas, Vivian Paraskevi; Mendez, Kevin; Katz, RavivPurpose: The most widely used classifications of age-related macular degeneration (AMD) and its severity stages still rely on color fundus photographs (CFPs). However, AMD has a wide phenotypic variability that remains poorly understood and is better characterized by OCT. We and others have shown that patients with AMD have a distinct plasma metabolomic profile compared with controls. However, all studies to da...
Topography-Guided Corneal Crosslinking for Keratoconus: Is It Enough to Treat t...
Cortinhal, Telmo; Gil, João; Rosa, Andreia; Quadrado, Maria João; Murta, JoaquimINTRODUCTION: Our objective is to report topographic and refractive outcomes in the first year following topography guided corneal crosslinking (TG-CXL) for keratoconus, with special focus given to the morphological changes in the superior, non-treated, corneal stroma. METHODS: Retrospective study. We included patients with progressive keratoconus who underwent TG-CXL: The epithelium was removed using photother...
Refining the morphological characteristics of Dipolydora capensis(Day, 1955) an...
Radashevsky, Vasily I; Martin, Daniel; Gil, JoãoTogether with Syllidae, Nereididae and Eunicidae, Spionidae is one of the four more speciose families of polychaete annelids in southern Africa, comprising 25% of the known species and 53–85% of the unresolved cosmopolitans. Among southern African spionids, the genus Dipolydora Verrill, 1881 particularly requires further revision and, in this paper, we contribute by refining the morphological characteristics of...

Surgical Management of Bilateral Limbal Stem Cell Deficiency
Lomelino Pinheiro, Rosa; Gil, João; Quadrado, Maria João; Murta, JoaquimAt the age of 43 years-old, a man was left with bilateral limbal stem cell deficiency after an ocular alkaline burn with lime, which resulted in corneal opacification. After multiple unsuccessful surgical attempts to restore vision, including penetrating keratoplasties and Boston keratoprosthesis, visual acuity was counting fingers in the left eye. At 73 years of age, the patient underwent another surgery in hi...
Tear Film Mediators After Corneal Cross-Linking: Methodology Validation
Costa, Celso; Araújo, Mariana; Rosa, Andreia; Gil, João; Quadrado, Maria João; Tavares, Cristina; Costa, Esmeralda; Fernandes, Rosa; Costa, LígiaIntroduction: Currently, the gold-standard treatment of progressive keratoconus (KC) is corneal collagen cross-linking (CXL), in which riboflavin and ultraviolet-A radiation increase the corneal biomechanical rigidity, arresting progression. However, post-operatory results vary significantly among patients. Although it has been suggested that corneal thickness, cone location and patient’s age are important fact...
New sublittoral species of Laonice (Annelida: Spionidae) from Southern Asian co...
Sikorski, Andrey; Pavlova, Luudmila; Martin, Daniel; Gil, JoãoFour new species of Laonice (Annelida: Spionidae) are described from the southern and southeastern coasts of Asia: L. (Laonice) persica sp. nov., L. (Laonice) siamica sp. nov., L. (Sarsiana) apicelamella sp. nov. and L. (Sarsiana) andamanica sp. nov. Materials were collected within the scope of different environmental surveys performed by the consulting company Creocean, ranging from the Persian Gulf (Indian Oc...
Corneal Collagen Cross-Linking in Pediatric Patients: Ten Year Experience
Félix, Raquel; Gonçalves, Guilherme; Gil, João; Costa, Esmeralda; Rosa, Andreia; Tavares, Cristina; Quadrado, Maria João; Murta, JoaquimINTRODUCTION: Keratoconus (KC) is a corneal ectatic disorder characterized by pro- gressive corneal thinning and steepening. Corneal collagen cross-linking (CXL) uses riboflavin and ultraviolet-A radiation to induce cross-links in the stromal collagen, increasing its biomechanical rigidity and halting the progression of KC. Different protocols of CXL have been proposed throughout the years to improve clinical r...
Taxonomic review of Gallardoneris nonatoi (Ramos, 1976) comb. nov. (Annelida, ...
Martin, Daniel; Estefa, Jordi; Gil, JoãoThe small Lumbrineridae Gallardoneris iberica Martins, Carrera-Parra, Quintino & Rodrigues, 2012 was first described as new to science based on specimens from Portuguese waters. Then, it was successively reported from several south European areas, including Spain, Italy, Greece, and Cyprus. Here evidence is presented that G. iberica should be placed in synonymy with Lumbrineris nonatoi Ramos, 1976, originally d...
