—The Microwave Imaging Radiometer by Aperture Synthesis (MIRAS) is the single payload of the European Space Agency's (ESA) Soil Moisture and Ocean Salinity (SMOS) Earth Explorer Opportunity mission. MIRAS will be the first two-dimensional aperture synthesis radiometer for earth observation. Two-dimensional aperture synthesis radiometers can generate(More)
Purpose. To review the proposed pathogenic mechanisms of age macular degeneration (AMD), as well as the role of antioxidants (AOX) and omega-3 fatty acids ( ω -3) supplements in AMD prevention. Materials and Methods. Current knowledge on the cellular/molecular mechanisms of AMD and the epidemiologic/experimental studies on the effects of AOX and ω -3 were(More)
OBJECTIVE To evaluate the association between insulin resistance and diabetic macular oedema in type 2 diabetes. METHODS Patients with type 2 diabetes who agreed to undergo blood sampling were enrolled into this cross-sectional study. Patients who had received treatment for macular oedema within the past 3 months and those with other retinal diseases were(More)
Retinal dystrophies (RD) are major causes of familial blindness and are characterized by progressive dysfunction of photoreceptor and/or retinal pigment epithelium (RPE) cells. In this study, we aimed to evaluate and compare the therapeutic effects of two pluripotent stem cell (PSC)-based therapies. We differentiated RPE from human embryonic stem cells(More)
PURPOSE To evaluate macular retinal ganglion cell-inner plexiform layer (GCIPL) thickness changes after Brilliant Blue G-assisted internal limiting membrane peeling for idiopathic macular hole repair using a high-resolution spectral-domain optical coherence tomography (SD-OCT). METHODS 32 eyes from 32 patients with idiopathic macular holes who underwent(More)
This is the second part of the article under the same name published in the previous issue of RED. It was then that we stated a vision of the selection and sequencing of learning objects in the context of curricular planning, from the constructivist perspective. In the field of web-based training, we pointed out the importance of having tools and autonomous(More)
– The SMOS (Soil Moisture and Ocean Salinity) mission will provide from 2007 onwards global maps of soil moisture over land and sea surface salinity over ocean. The radiometry group of the Technical University of Catalonia (UPC) in Barcelona has been involved either in the definition of the SMOS single payload, MIRAS (Microwave Imaging Radiometer by(More)
