Does teacher certification in mathematics improve high school special education students' performance on the High School Proficiency Assessment?: a preliminary investigation
No full textThis prelimary investigation examined the impact of teacher mathematics certification on high school special education students’ scores on the High School Proficiency Assessment (HSPA) in an urban public school setting. The sample included 76 eleventh grade students classified as special education under IDEA. The student sample represented 70% of males and 30% of females from culturally and economically diverse backgrounds. Five teachers federally classified as highly qualified were included. Out of the teacher sample, four held state certifications in mathematics and one was not certified. Research questions and hypotheses were examined using inferential statistical tests (2-sample t-tests) and effect sizes. Results indicated that special education students who were taught by HQTs certified in mathematics scored significantly better on the Mathematics section of the HSPA than special education students who were taught by HQTs non-certified mathematics teachers. Effect sizes indicated small practical and meaningful differences. Results are outlined and directions for future research are discussed.Psy.DIncludes bibliographical referencesby Maria Angela Staropol
MURINE EXPERIMENTAL MODEL OF PEYRONIE'S DISEASE: A PILOT STUDY
No full textINTRODUCTION AND AIM OF THE STUDY
The Peyronie's disease (PD) is an idiopathic disorder of connective tissue ot the penis, that involves the tunica albuginea of the corpora cavernosa and the adjacent areolar space. Many studies have tried to identify risk factors associated with PD and the role of inflammation and free radicals in the pathogenesis of plaque seems to be important. It is a growing clinical evidence to support the therapeutic potential of mesenchymal stem cells for the revascularization of ischemic tissues and the recovery of their function and histological findings has assumed a possible application of lipofilling technique in patients with PD. The objective of this experimental study is the creation of a murine experimental model of PD, evaluating with MRI the penis of the rats (feasibility study), in order to plane the application of lipofilling technique in an animal model.
MATERIALS and METHODS
Four male Wistar rats were anesthetized, fixed in prone position and subjected to MRI; image acquisition was performed using a scanner Biospec (Bruker, Karlsruhe, Germany) equipped with a horizontal magnet operating at 4.7 Tesla with opening of 33 cm (Oxford Ltd, Oxford, UK).
The animals underwent, subsequently, an injection of thrombin in the tunica albuginea, using a 1 mL syringe with needle 30 G, opening the dartos. MRI images were acquired in the same manner as described above at 7 and 21 days after injection with incision of the Dartos
RESULTS
The MRI acquisitions, both in coronal and axial projection, showed an adequate visibility of the anatomical structures. At 7 days after thrombin injection with the Dartos incision it was evident an oedematous portion, visible as a hyperintense area, located at the injection area.
At 21 days after injection, oedema was partially resolved: the injection part of the hyperintense area remains unchanged, while the remaining area appears to be part of a re-absorption and re-organization process.
Since none of the various treatment modalities currently available for the management of PD is able to bring healing, the researchers' attention is increasingly directed towards innovative treatment programs, such as the use of stem cells of mesenchymal origin. Since there is no data in the literature concerning the role of stem cells in management of PD, we planned to develop a murine model of stable IPP, monitored with imaging (MRI). At the present time, the research in PD is hampered by the lack of universally accepted animal model and this is likely attributed to the limited insight into PD mechanisms and the difficulties faced by current animal models to truly represent the complexity and complete spectrum of human disease
Gli avvenimenti storici come rivelazione L’incipit della Legatio ad Caium di filone di Alessandria
No full textIn the incipit of Legatio ad Caium of Philo of Alexandria anthropological and theological concepts are expressed which do not appear immediately relevant to the story: the narration of dramatic historical circumstances which the author personally lived through. The analysis of the specific contents reveals the connection betwen fundamental religious and cultural themes which are reoccurring themes in the various works of Philo. The introduction does not place ideology a priori but his considerations are evidence of a method of judgement of historical events
Animal experimental model of Peyronie's disease: a pilot study.

Critical points in understanding the Italian version of the IIEF 5 questionnaire.
No full textPURPOSE: The aim of these study is to assess the understanding of the Italian
version of the IIEF-5 questionnaire (International Index of Erectile Function)
and the impact of patient's demographic and clinical characteristics on it.
MATERIALS AND METHODS: Each patient was asked to self complete the Italian
version of the IIEF-5 questionnaire and to self report demographic information
and any difficulties to complete the questionnaire and which question was
considered more difficult to understand.
RESULTS: A total of 89 patients were included in this study. Patients mean age
was 61.2 +/- 15.4 (standard deviation = SD) years. The mean IIEF score at the
time of the visit was 13.5 +/- 8.5 (SD). The questions considered more difficult
to understand were number 5 (26%), number 4 (20%) and number 1 (20%).
Statistically significant differences between patients with and without problems
in completing the questionnaire were found in terms of education level (p =
0.0026).
CONCLUSIONS: Patients with a lower educational level have more difficulties in
understanding the questionnaire and the most difficult questions are items number
5, 4 and 1
