Green Design of Novel Starch-Based Packaging Materials Sustaining Human and Environmental Health
2021
A critical overview of current approaches to the development of starch-containing packaging, integrating the principles of green chemistry (GC), green technology (GT) and green nanotechnology (GN) with those of green packaging (GP) to produce materials important for both us and the planet is given. First, as a relationship between GP and GC, the benefits of natural bioactive compounds are analyzed and the state-of-the-art is updated in terms of the starch packaging incorporating green chemicals that normally help us to maintain health, are environmentally friendly and are obtained via GC. Newer approaches are identified, such as the incorporation of vitamins or minerals into films and coati…

Prefazione a Messina, R., "La strage negata"
2016
"Il 19 ottobre del 1944 si consumò a Palermo uno degli eventi più drammatici dell'immediato dopoguerra: truppe dell'esercito italiano aprirono il fuoco su centinaia di cittadini che, al grido di 'pane, pasta e lavoro!', sfilavano per il centro della città in una pacifica protesta contro il carovita. 24 tra i manifestanti, e tra di loro bambini e ragazzi, rimasero uccisi; 156 furono feriti. [...] Ripercorrendo tutte le tappe dell'iter giudiziario dell'eccidio del 19 ottobre, e concentrandosi in particolare sull'analisi del processo svoltosi presso il tribunale militare di Taranto nel febbraio del 1947, Rino Messina ci dimostra come dietro il paravento della "tutela dell'ordine pubblico" si n…
La historia de la dinastía en imágenes : Martín el Humano y el rollo genealógico de la Corona de Aragón
2002
Este artículo estudia el rollo genealógico de la Corona de Aragón conservado hoy en la biblioteca del monasterio de Poblet. La obra debió ser encargada por el rey Martín el Humano (1396-1410) para conmemorar a sus predecesores en el trono y, probablemente, servir de ejemplo a su hijo y presunto sucesor, Martín el Joven, rey de Sicilia, antes de su muerte, acaecida en 1409. El autor analiza el carácter de las imágenes reales pintadas en el pergamino, con el fin de precisar el significado político y cultural del rollo en relación con textos históricos y otros manuscritos iluminados que pueden vincularse a la corte durante el reinado de Martín el Humano. Las imágenes de los antiguos reyes de A…
Kinetics of Anti-Hepatitis B Surface Antigen Titers in Nurse Students after a Two-Year Follow-Up
2020
Infection caused by hepatitis B virus (HBV) can be prevented through a safe and effective vaccine. This study analysed the kinetics of serum antibodies against hepatitis B surface antigen (HBsAg) (anti-HBs) titers in relation to previous vaccine boosters in Italian nursing students who were followed up for two years. Serum anti-HBs titers were evaluated at the first visit, after vaccine booster (if required) and at visit after two years. Overall, 483 students (mean age = 21.7 years
Health care spending structures in Poland, Latvia, Lithuania and Estonia over the years as compared to other EU countries
2018
Abstract After joining the European Union in 2004, the post-communist countries have dramatically changed their structure of expenditure for medical services. The cause of this is legislative and ownership changes in the new economy. The study analyzed the expenditure on medical services in the European Union with a special focus on Poland, Latvia, Lithuania and Estonia. The European Union countries were divided into clusters using different methods, that is, Ward’s, Two Step and Centroid Clustering. In the paper, the structure and changes in health expenses were presented according to the types of expenditures over the years 2004-2015. Countries were assigned to clusters based on three var…
Sport for job. Differences in cortisol levels in a water polo team at different times of workout
2018
Agonistic sport represents a physically stressful situation associated with the release of catecholamine and cortisol that in turn influence the immune system. This study aimed to investigate the influence, in a team of water polo players, of the emotional processes characterizing the phase of waiting for the race on endocrine changes at the end of an official match. Thirteen professional water polo players participated in this study. Each player provided two saliva samples before and after three different time phases: (1) rest time, (2) workout and (3) competition. The results of the present study showed a significant increase in salivary cortisol levels before and after the competition an…
Color Stabilization of Apulian Red Wines through the Sequential Inoculation of Starmerella bacillaris and Saccharomyces cerevisiae
2021
Mixed fermentation using Starmerella bacillaris and Saccharomyces cerevisiae has gained attention in recent years due to their ability to modulate the qualitative parameters of enological interest, such as the color intensity and stability of wine. In this study, three of the most important red Apulian varieties were fermented through two pure inoculations of Saccharomyces cerevisiae strains or the sequential inoculation of Saccharomyces cerevisiae after 48 h from Starmerella bacillaris. The evolution of anthocyanin profiles and chromatic characteristics were determined in the produced wines at draining off and after 18 months of bottle aging in order to assess the impact of the different f…
Toward Mechanistic Design of Surrogate Buffers for Dissolution Testing of pH-Dependent Drug Delivery Systems
2020
The in vivo dissolution of enteric-coated (EC) products is often overestimated by compendial in vitro dissolution experiments. It is of great interest to mimic the in vivo conditions as closely as possible in vitro in order to predict the in vivo behavior of EC dosage forms. The reason behind this is the overly high buffering capacity of the common compendial buffers compared to the intestinal bicarbonate buffer. However, a bicarbonate-based buffer is technically difficult to handle due to the need for continuous sparging of the media with CO2 to maintain the desired buffer pH. Therefore, bicarbonate buffers are not commonly used in routine practice and a non-volatile alternative is of inte…
Lower secondary school pupils’ written descriptions of their experiences with bullying and the tendency to seek help
2021
The purpose of this study was to examine lower secondary school students’ (n = 223) descriptions of bullying and their experiences with the phenomenon. Students at three schools in Norway completed a survey containing open-ended questions. We employed a mixed-methods analytical approach in which responses were coded thematically and then quantified. Findings indicate that students viewed bullying in a manner consistent with prevalent definitions in the literature. However, they were often unsure whether social conflicts they had experienced would be considered bullying. School was clearly featured as the primary arena for bullying, although bullying in free-time activities and on social med…
