Analysis of a database to predict the result of allergy testing in vivo in patients with chronic nasal symptoms.
2014
Background This article uses the logistic regression model for diagnostic decision making in patients with chronic nasal symptoms. We studied the ability of the logistic regression model, obtained by the evaluation of a database, to detect patients with positive allergy skin-prick test (SPT) and patients with negative SPT. The model developed was validated using the data set obtained from another medical institution. Methods The analysis was performed using a database obtained from a questionnaire administered to the patients with nasal symptoms containing personal data, clinical data, and results of allergy testing (SPT). All variables found to be significantly different between patients w…

In actinomycetes, antibiotic production is often associated with a morpho-physiological differentiation program that is regulated by complex molecular and metabolic networks. Many aspects of these regulatory circuits have been already elucidated and many others still deserve further investigations. In this regard, the possible role of many small open reading frames (smORFs) in actinomycete morpho-physiological differentiation is still elusive. In Streptomyces coelicolor, inactivation of the smORF trpM (SCO2038) – whose product modulates L-tryptophan biosynthesis – impairs production of antibiotics and morphological differentiation. Indeed, it was demonstrated that TrpM is able to interact w…
Teacher–student relationship and students’ social competence in relation to the quality of educational dialogue
2022
Teacher–student relationship and students’ social competence were investigated in relation to the quality of educational dialogue. The data consisted of 151 video-recorded Grade 2 lessons. The teachers (N = 50) also rated their students’ (N = 664) social competence and the teacher–student relationship. In terms of teacher–student relationships, closeness associated positively while conflict associated negatively with high quality dialogue. Regarding students’ social competence, cooperation skills and empathy linked positively while disruptiveness linked negatively with high quality dialogue. The findings provide new knowledge on how different student-related factors may support or prevent t…
Consapevolmente intelligenti: un’indagine esplorativa sull’uso dei social network nella scuola primaria
2017
Abstract – Social Networks are a noteworthy opportunity to build a more caring and responsible society, a practice that is assimilated by learning to use the Web in a conscious way. The media competence takes the form of expertise both to active participation to the Web and to society. The focus is on the need to acquire the know-how to exploit the media, with particular reference to social networks, in a clever way so as to make them intelligent instruments. From an educational point of view, Social Networks offer a different potential because they are able to support the functions of socialization, of sharing and of coordination; to encourage dialogue, promote resources sharing and improv…
Mobile Apps and Social Media
2017
1The increasing penetration of smartphones among global population, especially among youth and children, has define a mobile and interactive media use without any precedent. A global connected world is the context in where our offspring are developing self-competences in media literacy because they manage technological devices at very early ages. This context is the state of affairs of this article in which we present two different steps: firstly, a theoretical study, showing the impact of mobile devices, focusing on smartphones and mobile applications where the question arisen is: What are children and young doing while online? Media literacy is also described in order to apply its dimensi…
Qualitative mucin disorders in patients with primary Sjögren's syndrome:a literature review
2020
Background It is a common opinion that Primary Sjögren Syndrome (pSS) damages the exocrine glands and determines the reduction of secreted saliva, some studies show that there are qualitative anomalies of the mucins produced in saliva, including MUC7, MUC5B, MUC1. The purpose of this study is to trace all the information useful to establish whether there is a qualitative or quantitative defect of the mucins in the pSS. Material and Methods We reviewed the literature by looking for publications relevant to the topic in electronic databases. Sixteen articles met the search criteria. The studies were divided into two categories, those that studied the rheological characteristics of the saliva …
Developing inclusive pre-service and in-service teacher education : Insights from Zanzibar primary school teachers
2017
Developing inclusive teacher education to improve learning and schooling for all children is attracting increasing interest worldwide. This study examined teachers’ insights into the development of inclusive teacher education by drawing on collaborative action research conducted by 20 primary school teachers in Zanzibar, Tanzania. The data were collected through semi-structured interviews and self-reflective journals kept by the teachers and the first author. The qualitative thematic content analysis revealed: (1) the need to embed inclusive education and action research into pre-service and in-service teacher education curricula and (2) both school-based organisational learning and school–…
il volto della morte: le maschere funerarie della sepoltura dei preti morti di Gangi
2014
riassunto — Le mummie moderne e il signifcato recondito della doppia sepoltura nelle culture mediterranee moderne sono da tempo ampiamente dibattuti. In questo lavoro si discute di una particolare “collezione” di corpi di ecclesiastici, mummifcati ed esposti in un comune montano madonita della Sicilia, Gangi. I corpi, principalmente risalenti al XIX secolo, mummifcati per colatura come nella tradizione del tempo e vestiti degli abiti talari, sono esposti nel piano sottostante della Chiesa Madre, in quella che nella tradizione è detta la “fossa dei parrini” (fossa dei preti). Le mummie, a differenza di altri siti siciliani e mediterranei, sono altresì corredate di sonetto commemorativo e di …
Determination of glyphosate and its metabolite aminomethylphosphonic acid in fruit juices using supported-liquid membrane preconcentration method wit…
2005
Abstract The application of supported-liquid membrane (SLM) technique for effective extraction of N -(phosphonomethyl)glycine (glyphosate) and its primary metabolite aminomethylphosphonic acid (AMPA) from juices (orange, grapefruit, apple and blackcurrant) in combination with HPLC-UV detection after derivatization with p -toluenesulphonyl chloride (TsCl) is presented. The influence of various parameters such as the composition of acceptor phase, flow-rate, concentration of analytes, on the performance of extraction procedure, was studied. It was shown that by appropriate manipulation of SLM parameters the level of detection could be significantly improved. The influence of SLM conditions on…
The value of synthetic linear epitope analogues of La/SSB for the detection of autoantibodies to La/SSB; specificity, sensitivity and comparison of m…
1998
SUMMARY In a previous study it was shown that La/SSB contains four linear epitopes, p147–154, p291–302, p301–318 and p349–364. The aim of the present study was to investigate the value of the synthetic epitope analogues of the La/SSB autoantigen for the detection of antibodies to La/SSB, in comparison with recombinant La and fragments of this protein. A total of 122 sera with anti-La/SSB activity, from patients with primary Sjögren's syndrome (pSS) or systemic lupus erythematosus (SLE), were tested in various peptide-based assays. In addition, 62 sera from pSS or SLE patients with other autoantibody specificities and 95 sera from healthy individuals were used as controls. The autoantibody s…
