We modeled the problem of identifying how close two proteins are structurally by measuring the dissimilarity of their contact maps. These contact maps are colored images, in which the chromatic information encodes the chemical nature of the contacts. We studied two conceptually distinct image-processing algorithms to measure the dissimilarity between these(More)
This paper introduces a methodology for adding color to grayscale images in a way that is completely automatic. Towards this goal, we build on a technique that was recently developed to transfer colors from a user-selected source image to a target grayscale image. More specifically, in order to eliminate the need for manual selection of the source image, we(More)

Some sort of restriction of the pouch emptying is supported by many surgeons to allow a sustained weight loss through the use of a ring placed circumferentially around the gastric pouch. Most previous studies focused on the length of the ring, not the actual diameter of the gastric pouch outlet. This study aims to evaluate the association between the actual(More)
In this work we model the problem of identifying how close structurally two proteins are as a problem of measuring the similarity between color images that represent their contact maps, where the chromatic information encodes the chemical nature of the contacts. We study two conceptually distinct methods to measure the similarity between such contact maps:(More)
PURPOSE To evaluate the effects of biliary stenting in rats through analysis of collagen and elastin deposition in the bile ducts. METHODS Twenty male rats underwent midline laparotomy, duodenotomy and transampullary stenting of the common bile duct with a 22Fr plastic stent. Animals were randomized in 4 groups, with 5 components in each: (I) control,(More)
