Development and application of analytical and statistical techniques for the non-invasive monitoring and analysis of cultural heritage
Decoding molecular profiling of exhaled breath condensate in respiratory diseases
Advanced molecular profiling techniques may be useful in chronic respiratory disorders to understand metabolomic alterations and tailor specific treatments. Exhaled breath condensate (EBC) provides a non-invasive way to access the lung environment, which can be profiled using omics techniques such as mass spectrometry and NMR

The secretome signature of malignant mesothelioma cell lines
The secretome is the complex set of molecules secreted by cells; these molecules play a key role in cell signaling, communication and migration. Secretomics has been already used to discover new potential diagnostic biomarkers and therapeutic agents and to elucidate key autocrine pathways. Malignant mesothelioma (MMe), an extremely aggressive tumor, is characterized by a long latency period (20-30years), a poor prognosis, and limited effective therapies. MMe has a highly secretory cell type, and the factors released by cells may act in an autocrine or paracrine fashion on tumor and stroma, where they may modulate the extracellular environment. The aim of this work is to characterize the secretome of two MMe cell lines, MM98 and REN, in comparison with a mesothelial cell line Met5A, in order to evaluate differences and similarities of these two different MMe cancer model systems, and to identify potential biomarkers. We performed quantitative shotgun proteomics using SWATH-MS technology and we identified a total of 421 proteins, 112 expressed in the secretome of REN cells, 208 expressed in the secretome of MM98 cells and 189 secreted by mesothelial cells; 25 proteins are shared by the two mesothelioma cell lines
Prediction and classification of the degradation state of plastic materials used in modern and contemporary art
Algorithms for warping of 2-D PAGE maps
Software-based image analysis of 2-D PAGE maps is an important step for the investigation of proteome. Warping algorithms, which are employed to register spots among gels, are able to overcome the difficulties due to the low reproducibility of this analytical technique. Over the years, the research of new matching and warping mathematical methods has allowed the development of several routine applications of easy-to-use software. This chapter describes common and basic spatial transformations used for the alignment of protein spots present in different gel maps; some recently new approaches are also presented
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
