Automated analysis of images for molecular quantification in immunohistochemistry.
2018
The quantification of the expression of different molecules is a key question in both basic and applied sciences. While protein quantification through molecular techniques leads to the loss of spatial information and resolution, immunohistochemistry is usually associated with time-consuming image analysis and human bias. In addition, the scarce automatic software analysis is often proprietary and expensive and relies on a fixed threshold binarization. Here we describe and share a set of macros ready for automated fluorescence analysis of large batches of fixed tissue samples using FIJI/ImageJ. The quantification of the molecules of interest are based on an automatic threshold analysis of im…
Does Urban Security Modulate Transportation Choices and Travel Behavior of Citizens? A National Study in the Dominican Republic
2020
Introduction: Traditionally, the scientific literature on urban and transportation dynamics addresses many topics, but the security-related outcomes of users remain a pending issue, especially in emerging countries and their cities. Nevertheless, recent evidence suggests that, especially in developing countries, security issues may influence people’s decision-making in the choice of transport means, daily urban-trip patterns and road behaviors of users. Objective: The purpose of this study was to explore the relationships between the perceived security (in both urban environments and public transport systems) and the daily-travel behavior and trip patterns of the Dominican Republic populati…
Human capital in Spain and its distribution by provinces (1964-2013)
2015
The regularly-updated database “Human capital in Spain and its distribution by provinces” provides information about the accumulation of human capital in Spain over the last five decades. The human capital estimates included in this database contain a wide range of information on how education levels in Spain have evolved, classified according to the level of studies completed and other human capital indicators. The database includes information that has been updated until the second trimester of 2013. It can be accessed at http://www.ivie.es/en/banco/caphum/series.php.
Standard testing of photovoltaic modules for use in renewable energy education
2015
A photovoltaic laboratory exercise has been devised and used in the educational curriculum of the Renewable Energy Programme at the University of Jyväskylä. The purpose of the experimental tasks is to give students of renewable energy a good understanding of standard testing procedures used in industry for characterising photovoltaic modules and to provide practical skills in sizing simple photovoltaic installations. Herein the experimental set-up, basic theory and measurement procedure are described. The experimental apparatus is simple to assemble and uses both standard laboratory equipment and recycled components. From the experimental results, the tested PV cell had a maximum efficiency…
Workshop: iPads in Upper Secondary School Chemistry Education
2014
At the workshop arranged at the National Days of Chemical Education the participants had an opportunity to try out various Ipad apps and methods for utilizing them in chemistry education. The themes were based on the apps used during chemistry teacher education course arranged by the department of chemistry and methods developed on the teacher training school at the University of Jyväskylä. The apps used included Socrative Student, Google Drive, Graphical Analysis, ChemDoodle ja QR-reader. Out of these Socratice, which collects students answers to questions created by the teacher, was considered easy-to-use and the most useful by the participants. The participants also felt, that the worksh…
Drifting Down the Technologization of Life: Could Choreography-Based Interaction Design Support us in Engaging with the World and our Embodied Living?
2013
The development of interactive technology is often based on the assumption of need to reduce the physical action and cognitive load of the user. However, recent conceptualizations, supported by research in various fields of science, emphasize human physical action in cognitive processes and knowledge formation. In fact, physical and closely related imaginary movement can be seen as the quintessence of humanity. Acknowledging this should imply a new approach to the design of interactive technology. In the current study, we propose a choreographic approach for shifting the focal point of interaction design to the aspects of human activity and movement within a technologized context. Hence, th…
Data concerning the protein absorption and retention properties of xyloglucan-based hydrogel film
2018
In wound dressing applications, exudate absorption and retention are important properties. The data presented here assess the ability of the crosslinked xyloglucan-poly(vinyl alcohol) hydrogel films (XG-PVA), described in "Xyloglucan-based hydrogel films for wound dressing: Structure-property relationships" (Ajovalasit et al., 2018) [1] and "Biocompatibility, hemocompatibility and antimicrobial properties of xyloglucan-based hydrogel film for wound healing application" (Picone et al., 2019), to absorb and retain proteins. These properties were investigated by Comassie blue staining and electrophoresis of Fetal Serum Proteins. (C) 2018 The Authors. Published by Elsevier Inc. This is an open …
Do fire severity effects on soil change in space and time in the short-term? What ash tells us
2013
n the absence of data, the impact of fire, especially wildfires, is measured analysing the fire severity. This post-fire assessment is very useful because allow to identify the degree of destruction imposed by the fire. Among the techniques used to determine fire severity, ash colour is often used, that permit identify the degree of organic matter consumption (darker ash uncompleted combustion, lighter ash completed combustion). The objective of this paper was observed if fire severity changes in space and time, according to ash colour analysis, applying an index. The ash colour analysis was carried out one and fifteen days after the fire. In this area we identified ash with four different …
Predictors of therapy failure in newly diagnosed pulmonary tuberculosis cases in Beira, Mozambique.
2018
Abstract Objective Tuberculosis (TB) remains a major global health issue, ranking in the top ten causes of death worldwide. A deep understanding of factors influencing poor treatment outcomes may allow the development of additional treatment strategies, focused on the most vulnerable groups. Aims of the study were: (i) to evaluate the treatment outcome among TB subjects followed in an outpatient setting and (ii) to analyze factors associated with treatment failure in newly diagnosed patients with pulmonary TB in Beira, the second largest city of Mozambique. Results A total of 301 TB adult patients (32.6% females) were enrolled. Among them, 62 (20.6%) experienced a treatment failure over a 6…
Oral verruciform xanthoma and erythroplakia associated with chronic graft-versus-host disease: A rare case report and review of the literature
2017
Abstract Background Oral verruciform xanthoma is an uncommon benign lesion. Although oral verruciform xanthoma occurs in healthy individuals, it has been also reported in association with some inflammatory conditions. The aim of this study is to report a case of oral verruciform xanthoma associated with chronic graft-versus-host disease and to review the literature on this topic. Case presentation A 47-year-old Caucasian male presented to the Sector of Oral Medicine “V. Margiotta”, University Policlinic “P. Giaccone” of Palermo complaining of a mass on the gingiva. He first noticed the painless mass 1 year ago. He reported to have undergone allogenic hematopoietic stem cell transplantation …
