Predicting antitrichomonal activity: A computational screening using atom-based bilinear indices and experimental proofs
2006
Existing Trichomonas vaginalis therapies are out of reach for most trichomoniasis people in developing countries and, where available, they are limited by their toxicity (mainly in pregnant women) and their cost. New antitrichomonal agents are needed to combat emerging metronidazole-resistant trichomoniasis and reduce the side effects associated with currently available drugs. Toward this end, atom-based bilinear indices, a new TOMOCOMD-CARDD molecular descriptor, and linear discriminant analysis (LDA) were used to discover novel, potent, and non-toxic lead trichomonacidal chemicals. Two discriminant functions were obtained with the use of non-stochastic and stochastic atom-type bilinear in…
Bond-based bilinear indices for computational discovery of novel trypanosomicidal drug-like compounds through virtual screening
2014
Two-dimensional bond-based bilinear indices and linear discriminant analysis are used in this report to perform a quantitative structure-activity relationship study to identify new trypanosomicidal compounds. A data set of 440 organic chemicals, 143 with antitrypanosomal activity and 297 having other clinical uses, is used to develop the theoretical models. Two discriminant models, computed using bond-based bilinear indices, are developed and both show accuracies higher than 86% for training and test sets. The stochastic model correctly indentifies nine out of eleven compounds of a set of organic chemicals obtained from our synthetic collaborators. The in vitro antitrypanosomal activity of …
Harmonization of QSAR Best Practices and Molecular Docking Provides an Efficient Virtual Screening Tool for Discovering New G-Quadruplex Ligands
2015
Telomeres and telomerase are key players in tumorogenesis. Among the various strategies proposed for telomerase inhibition or telomere uncapping, the stabilization of telomeric G-quadruplex (G4) structures is a very promising one. Additionally, G4 stabilizing ligands also act over tumors mediated by the alternative elongation of telomeres. Accordingly, the discovery of novel compounds able to act on telomeres and/or inhibit the telomerase enzyme by stabilizing DNA telomeric G4 structures as well as the development of approaches efficiently prioritizing such compounds constitute active areas of research in computational medicinal chemistry and anticancer drug discovery. In this direction, we…
Relationships of leisure-time physical activity and work ability between different occupational physical demands in adult working men
2019
Purpose: Leisure-time physical activity (LTPA) is known to be associated with positive health benefits, but the role of occupational physical demands remains inconsistent. The purpose of the current study was to assess the relationship between LTPA and work ability in different occupational physical activity (OPA) levels between young adult men. - Methods: We performed physical activity measurements in work and leisure time with the long version of International Physical Activity Questionnaire (IPAQ) and work ability with the Work Ability Index (WAI) in 921 Finnish employed male volunteer participants. The participants were divided into LTPA tertiles I ( 28 MET-h/week) and OPA tertiles I (0…
The Feasibility of a Text-Messaging Intervention Promoting Physical Activity in Shift Workers : A Process Evaluation
2023
Workplace health promotion programs (WHPPs) can improve shift workers’ physical activity. The purpose of this paper is to present the process evaluation of a text messaging health promotion intervention for mining shift workers during a 24-day shift cycle. Data collected from intervention participants with a logbook (n = 25) throughout the intervention, exit interviews (n = 7) and online surveys (n = 17) examined the WHPP using the RE-AIM (Reach, Efficacy, Adoption, Implementation and Maintenance) framework. The program reached 66% of workers across three departments, with 15% of participants dropping out. The program showed the potential to be adopted if the recruitment strategies are impr…
Contributions to the study of educational returns
2016
In Tunisia, enrollment rates in tertiary education had soared up over the past two decades. A significant increase of student annual flows imposed the implementation of reforms that led to an increase in the number of higher education institutions and universities. One of the challenges in Tunisia and many African countries is to improve the efficiency of education systems to promote employability and graduates employment. This thesis discuss the question of the efficiency of education from an economic approach based on returns to education in the labor market. The first chapter analyses private returns to education particularly higher education in African countries. Our findings highlight …
La gestione dei conflitti: un’analisi descrittiva dai Rapporti di Autovalutazione delle scuole della Provincia di Palermo
2019
Il presente contributo intende promuovere una riflessione sul tema della gestione dei conflitti in ambito scolastico a partire da un’analisi descrittiva dei Rapporti di Autovalutazione delle scuole del I ciclo della Provincia di Palermo riguardanti l’anno scolastico 2017/18. La rilevazione dei dati è avvenuta attraverso il portale del MIUR “Scuola in Chiaro”. In particolare, sono stati presi in considerazione gli indicatori appartenenti alla dimensione relazionale (3.2.f ) dell’area “Ambiente di apprendimento” della sezione “Processi” del RAV oltre agli eventuali indicatori elaborati dalla scuola e ai punti di forza e di debolezza elaborati sulla base di alcune domande stimolo fornite. L’an…
La presa in carico residenziale: percorsi di ricerca nelle comunità per minori.
2012
Le comunità residenziali possono essere concepite come “campi esperienziali”, luoghi di esperienza condivisa all’interno dei quali, nel qui e ora della quotidianità e nell’intreccio di storie, esperienze, culture, visioni del mondo, orientamenti e bisogni diversi, gli “abitanti” della comunità, minori e operatori, intrecciano reti relazionali complesse. L’esplorazione di tali campi esperienziali e del loro funzionamento, la definizione di setting di lavoro clinico e formativo nei quali avviare percorsi trasformativi, è l’interesse che ha mosso il progetto di ricerca e intervento che qui presentiamo. Nella prospettiva della valutazione del lavoro clinico e della qualità dei servizi offerti a…
Participatory tools and methods for community action. SESPAS Report 2018
2018
Resumen: La participación es un proceso que requiere la implicación de responsables de la política, del personal directivo y técnico de las instituciones, y de la ciudadanía, así como de la acción intersectorial e interdisciplinaria. Para generar cambios transformadores es necesaria una infraestructura que favorezca la participación y la acción planificada, reconociendo a todos los actores del proceso. Se precisan tiempo y compromiso para su continuidad a través de la producción conjunta de acciones, y de ahí la importancia de consolidar proyectos participativos que continúen más allá de los cambios políticos para que los servicios públicos sean sostenibles. La formación, el uso adecuado de…
The Last Ten Years of Regional Science: Advances in Theory and in Policy Evaluation
2020
Some months ago, the Scientific Board of AISRe and the Editor of this Journal asked us, also in our capacities as immediate Past Presidents of the Association, to edit a new celebratory special issue with a specific focus on the past ten years. We asked prominent Italian scholars in the field to review the most significant studies produced mostly in the past decade (including their own) and to address new topics that had not been covered by the previous celebratory issue or that had registered important advances since then.
