Mosaic aging

Study of resistance to cucumber mosaic virus watermelon mosaic virus and zucchini yellow mosaic virus in melon cultivars

Aging of the human photoreceptor mosaic: evidence for selective vulnerability of rods in central retina.

PURPOSE Because previous studies suggested degeneration and loss of photoreceptors in aged human retina, the spatial density of cones and rods subserving the central 43 degrees of vision as a function of age was determined. METHODS Cones and rods were counted in 27 whole mounted retinas from donors aged 27 to 90 years with macroscopically normal fundi. Photoreceptor topography was analyzed wi...

Mosaic chromosome 20q deletions are more frequent in the aging population.

Deletions on the long-arm of chromosome 20, del(20q), are common karyotypic abnormalities in myeloid disorders. Bioinformatic analyses of the B-allele frequency and log R ratio values from genome-wide association data have identified individuals who are mosaic for large structural abnormalities (>2 Mb). We investigated the most common autosomal event, namely mosaic del(20q), in 46 254 nonhemato...

Image Mosaic

We employ Convolutional Neural Networks with the VGG16 and VGG19 architecture to classify photographs that span four decades of professional photographic work by Mário Cabrita Gil. For each photograph, the 4096 dimension feature vector is reduced to two-dimensions by employing distributed Stochast Neighbor Embedding (t-SNE). Finally, the photographs are arranged according to their similarity va...

Explorer MOSAIC

Background: The recent availability of complete sequences for numerous closely related bacterial genomes opens up new challenges in comparative genomics. Several methods have been developed to align complete genomes at the nucleotide level but their use and the biological interpretation of results are not straightforward. It is therefore necessary to develop new resources to access, analyze, an...
