The purpose of a virtual laboratory is to support collaborative work of all the people who are involved in any stage of the experimental process. Problem Solving Environment (PSE) is an approach and a technology that is used for the definition and composition of complex applications, hiding programming and configuration details to the user that can concentrate instead only on the specific biological problem. PSE allows building virtual laboratories specialized for a specific domain, such as bioinformatics. At the University of Salento, we have developed ProGenGrid (Proteomics and Genomics Grid), a system which aims to provide a virtual laboratory where e-scientists can simulate biological experiments, composing existing analysis and visualization tools, monitoring their execution, storing the intermediate and final output and finally, if needed, saving the model of the experiment for updating or reproducing it at a later time. Different bioinformatics services and workflows have been deployed in the LIBI (International Laboratory of BioInformatics) project, aiming at setting up an advanced bioinformatics and computational biology laboratory, focusing on basic and applied research in modern biology and biotechnologies. In this paper we present recent developments in the ProGenGrid system, with a special focus on the possibility to configure a computational grid by using the workflow editor. This new feature of the system allows to the user to create his/her own personal grid on-the-fly, by adding, removing, or updating its computer configuration.","PeriodicalId":187652,"journal":{"name":"2012 25th IEEE International Symposium on Computer-Based Medical Systems (CBMS)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121951070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current requirement for extensive user interaction with commercially available computerized stereology systems limits the throughput of data collection. To increase the efficiency of this process, an algorithm was developed to automate data collection from stained objects in thick, transparent tissue sections. We present a novel approach to extract, count and classify stained objects of interest in 3D by linking them through a z-stack of images. Skeletonization and erosion are used to further segment the under segmented (overlapping) cells resulting from the extraction of out of focus cells in conjunction with in focus cells. Finally, 3D shape features, computed from the re-linked cells, are used for final classification of counted objects into “cells” and “not-cells”. We achieve a classification accuracy of 85% using SVM in a leave one-out experiment. The results demonstrate the effectiveness of our algorithm to count cells in 3D from thick, transparent tissue sections.","PeriodicalId":187652,"journal":{"name":"2012 25th IEEE International Symposium on Computer-Based Medical Systems (CBMS)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122381818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The benchmark procedure for ANAs diagnosis is the indirect immunofluorescence (IIF) assay performed on the HEp-2 substrate. Medical doctors first determine the fluorescence intensity exhibited by HEp-2 cells, and then report the staining pattern for positive wells only. With reference to staining pattern recognition, in the literature we found works recognizing five main patterns characterized by well-defined cell edges. These approaches are based on cell segmentation, a task that should be harder than the classification itself. We present here a method extending the panel of detectable HEp-2 staining patterns, introducing the centromere and cytoplasmic patterns, which do not show well-defined cell edges, and where a segmentation-based classification may fail. We apply a local approach which extracts SIFT descriptors and then classifies an image through the bag of visual words approach. This permits to represent complex image contents without applying the segmentation procedure. We test our approach on a dataset of HEp-2 images with large variability in both fluorescence intensity and staining patterns. Despite the large skew of the a-priori class distribution, our system correctly recognizes the 98.3% of samples, with a F-measure equal to 92.3%, 95.2% and 99.0%, for each class.","PeriodicalId":187652,"journal":{"name":"2012 25th IEEE International Symposium on Computer-Based Medical Systems (CBMS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126663030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
