ABSTRACT
We present MaREA4Galaxy, a user-friendly tool that allows a user to characterize and to graphically compare groups of samples with different transcriptional regulation of metabolism, as estimated from cross-sectional RNA-seq data. The tool is available as plug-in for the widely-used Galaxy platform for comparative genomics and bioinformatics analyses. MaREA4Galaxy combines three modules. The Expression2RAS module, which, for each reaction of a specified set, computes a Reaction Activity Score (RAS) as a function of the expression level of genes encoding for the associated enzyme. The MaREA (Metabolic Reaction Enrichment Analysis) module that allows to highlight significant differences in reaction activities between specified groups of samples. The Clustering module which employs the RAS computed before as a metric for unsupervised clustering of samples into distinct metabolic subgroups; the Clustering tool provides different clustering techniques and implements standard methods to evaluate the goodness of the results.
ABSTRACT
The authors present a clinical report of deforming mucocutaneous leishmaniasis of the nose in a native American woman, left untreated for 25 years. The nose was reconstructed using the local tissue displaced as flaps, and using cartilage grafts taken from the nasal septum and the ear shell. To the best of the authors' knowledge, the literature offers just 1 report on a similar patient.
