Inguinal Hernia: Defect Obliteration with the 3D Dynamic Regenerative Scaffold Proflor™.
2021
Prosthetic inguinal hernia repair presents significant challenges. Some of these, such as mesh fixation and quality of the biologic response, are still debated among surgeons. For example, there is no strong consensus regarding a specific condition that characterizes the surgical procedure during herniorrhaphy. This issue concerns management of the hernia defect, which in conventional hernia repair with flat meshes remains patent. However, a critical analysis of typical postoperative complications after inguinal hernia repair reveals that some of these adverse events are related to patency of the hernial opening. Postoperative discomfort, pain with specific movements and even hernia recurre…
Scaffolding by means of scientific concepts: a teacher-guided peer response activity
2018
The paper analyzes the performance of a university student on a peer response activity which is part of an assignment in a writing course for second-year students of English philology. With Vygotsky’s (1987) doctrine of scientific concepts as a lens, it looks at how in the course of the peer response activity the teacher and the students support one another in their respective attempts to teach and learn writing. Teacher support on tasks, known as scaffolding (e.g. Stone 1998), is based on the idea that instruction should provide for transfer of responsibility for a complex task from teacher to student (Vygotsky 1978; Wood, Bruner, & Ross 1976). Adopting the Vygotskian perspective, I explai…
Development of the Mental Imagery Scale for Preschool Children using Classical Test Theory and Item Response Theory
2020
This study aimed to develop a measure of mental imagery evaluation in preschool children. Three studies were conducted: Study 1 focused on the exploration of the factorial structure, reliability, and Item Response Theory (IRT) discrimination on a sample of children from 4 to 5 years old (N = 100; 50% males and 50% females); Study 2 focused on the confirmation of results about dimensionality on a sample of children from 4 to 7 years old (N = 170; 50% males and 50% females); and Study 3 focused on verifying criterion validity on a sample of children from 4 to 5 years old (N = 70; 47.1% males and 52.9% females). The results confirmed the hypothesis of three reliable factors underlying the scal…
Universal newborn hearing screening in the Italian Region of Sicily in 2018
2021
We have clarified the role of Universal Neonatal Hearing Screening (UNHS) for both early diagnosis and rapid treatment in order to improve the prognosis of the deaf child and reduce patient management costs. Although in Sicily UNHS has been progressively implemented, there is scarce data in the literature on this matter. Therefore, the main objective was to collect in the year 2018 the following data: number of newborns screened for hearing loss, number of infants "referred" to transiently evoked otoacoustic emissions (TEOAE), number of infants with pathologic auditory brainstem response (ABR) and number of infants affected by permanent hearing loss.UNHS monitoring was conducted through the…
A Dynamic Attribute-Based Authentication Scheme
2015
Attribute-based authentication (ABA) is an approach to authenticate users by their attributes, so that users can get authenticated anonymously and their privacy can be protected. In ABA schemes, required attributes are represented by attribute trees, which can be combined with signature schemes to construct ABA schemes. Most attribute trees are built from top to down and can not change with attribute requirement changes. In this paper, we propose an ABA scheme based on down-to-top built attribute trees or dynamic attribute trees, which can change when attribute requirements change. Therefore, the proposed dynamic ABA scheme is more efficient in a dynamic environment by avoiding regenerating…
Evaluation of a High School Practical Experience on Noise Pollution With Smartphones
2021
This work presents the evaluation of a practical experience on noise pollution based on the use of smartphones to check if it helps students to better understand the concepts related to this phenomenon. This evaluation has been done with a pre-post design in which 112 students, enrolled in the “Physics and Chemistry” course of the 1st year of non-compulsory high school, have first filled in a diagnostics questionnaire with 5 free response questions about their knowledge on the topic and then a pre-post questionnaire with 4 free response questions. The results show that the proposed practical experience is effective since a statistically significant improvement is obtained both globally and …
Energy self-consumers and renewable energy communities in Italy: New actors of the electric power systems
2021
Abstract The new European Directive RED-II on the promotion of the use of renewable energy sources has introduced the concept of the Renewable Energy Community. This new entity has the potential to change the relations among end-users and the latter and the other actors of the energy sector. In particular, the electrical sector appears the most influenced by the implementation of this paradigm. Indeed, the need for self-consumption and for exploiting the full potential of renewable energy in a Renewable Energy Community influences how the end-users exchange energy with the power grid, the rules for their connection to the grid, the implementation of Demand Response and other energy manageme…
Newly qualified teachers’ work engagement and teacher efficacy influences on job satisfaction, burnout, and the intention to quit
2011
Teacher policy is high on national agendas and countries are seeking to improve schools. Demands on schools and teachers are more complex and it is expected that a larger number of teachers will enter the profession. Studies indicate that the period when teachers are newly qualified is a peak time for leaving the profession. The purpose of this study was to investigate work engagement and teacher efficacy and their relationship to job satisfaction, burnout and the intention to quit among newly qualified teachers. 750 questionnaires were distributed to teachers who had less than six years experience as a teacher after they had completed their teacher education from one university in southern…
Low Grade Inflammation as a Common Pathogenetic Denominator in Age-Related Diseases: Novel Drug Targets for Anti-Ageing Strategies and Successful Age…
2010
Nowadays, people are living much longer than they used to do, however they are not free from ageing. Ageing, an inexorable intrinsic process that affects all cells, tissues, organs and individuals, is a post-maturational process that, due to a diminished homeostasis and increased organism frailty, causes a reduction of the response to environmental stimuli and, in general, is associated to an increased predisposition to illness and death. However, the high incidence of death due to infectious, cardiovascular and cancer diseases underlies a common feature in these pathologies that is represented by dysregulation of both instructive and innate immunity. Several studies show that a low-grade s…
Synthetic lethal metabolic targeting of cellular senescence in cancer therapy.
2013
Activated oncogenes and anticancer chemotherapy induce cellular senescence, a terminal growth arrest of viable cells characterized by S-phase entry-blocking histone 3 lysine 9 trimethylation (H3K9me3). Although therapy-induced senescence (TIS) improves long-term outcomes, potentially harmful properties of senescent tumour cells make their quantitative elimination a therapeutic priority. Here we use the Eµ-myc transgenic mouse lymphoma model in which TIS depends on the H3K9 histone methyltransferase Suv39h1 to show the mechanism and therapeutic exploitation of senescence-related metabolic reprogramming in vitro and in vivo. After senescence-inducing chemotherapy, TIS-competent lymphomas but …
