Mythopoiesis And Collective Imagination In Videogames

As videogames become more and more popular, their ability to generate and communicate mythologies (mythopoiesis) appears clearer. Pokémon, The Legend of Zelda, and Halo are just a few of the specific transmedial storyworlds created through (relatively few) years of reiteration. At the same time, recent examples of massively diffused products also picture remediations of heritage, folk tales, architecture, and other cultural elements, reaching users of any background. Franchises like Assassin’s Creed, God of War, or Final Fantasy take large inspiration from various cultural heritages. By doing so, video-ludic remediations add to previously shared imaginary some peculiar interactive (ergodic) features: since video games have specific features that imply interaction by (and with) the user, the remediated cultural elements acquire properties that were not present in any previous representation. The interest of this study is to enlighten how it is possible for blockbuster videogames to build over previous archetypes and imaginaries, creating common knowledge about certain cultural objects, myths, and figures, among players on a global scale. The main focus of this research will be Japanese cultural heritage representation in recent popular videogames such as Nioh, Ghost of Tsushima, and Sekiro: Shadows Die Twice. In a comparative analysis of these products, the study will try to underline the common elements of blockbuster remediations, while exploring the emerging interactive (ergodic) features that the mentioned videogames add to previously shared imaginary of portrayed cultural elements. Any emerging evidence will then serve to build a tentative framework or method to remediate and represent any given cultural element in future videogame projects that aim to properly communicate heritage on a large scale such as the global digital game market

Il sobborgo come utopia realizzata. Da Supercannes di J. G. Ballard a Il cerchio di D. Eggers

Se c’è qualcosa che caratterizza alcune famose narrazioni fantascientifiche degli ultimi cinquanta anni è una sorta di irrisolvibile ambiguità tra utopia e distopia. Il mondo rappresentato non è più chiaramente distopico al lettore fin dalle prime pagine come in Wells, Orwell, Bradbury o Dick ma le distinzioni si fanno più sfumate come nel Mondo nuovo di Huxley, forse il vero grande modello della distopia contemporanea. Nelle storie di Ballard o in più recenti saghe come The Giver e Divergent fino ad arrivare a romanzi come Il cerchio vengono mostrati mondi all’inizio apparentemente utopici che scivolano via via verso la distopia. Ma perfino alla fine resta sempre la sensazione che il mondo di partenza, così pacifico e sereno, non fosse poi così sbagliato, che quell’utopia, con alcuni doverosi aggiustamenti, avrebbe anche potuto funzionare. Da cosa deriva questa ambiguità? E perché permane pressoché invariata (con alcune importanti differenze tra le distopie tipicamente ballardiane e quelle degli anni Duemila) nell’ultimo mezzo secolo nonostante le profonde trasformazioni tecnologiche, politiche e sociali? Proviamo ad analizzare la natura di tali “utopie mascherate” (Ilardi, Loche, Marras 2018) prima di provare a ipotizzare una risposta a queste domande

The anxiolytic effect of probiotics: A systematic review and meta-analysis of the clinical and preclinical literature

A grant from the One-University Open Access Fund at the University of Kansas was used to defray the author's publication fees in this Open Access journal. The Open Access Fund, administered by librarians from the KU, KU Law, and KUMC libraries, is made possible by contributions from the offices of KU Provost, KU Vice Chancellor for Research & Graduate Studies, and KUMC Vice Chancellor for Research. For more information about the Open Access Fund, please see http://library.kumc.edu/authors-fund.xml.Background Probiotics have generated intensive research interest in recent years as a novel mode of treatment for physical and mental illness. Nevertheless, the anxiolytic potential of probiotics remains unclear. The present systematic review and meta-analysis aimed to evaluate the clinical and preclinical (animal model) evidence regarding the effect of probiotic administration on anxiety. Methods The PubMed, PsycINFO, and Web of Science databases were reviewed for preclinical and clinical studies that met the defined inclusion and exclusion criteria. The effects of probiotics on anxiety-like behavior and symptoms of anxiety were analyzed by meta-analyses. Separate subgroup analyses were conducted on diseased versus healthy animals, specific preclinical probiotic species, and clinical versus healthy human samples. Results Data were extracted from 22 preclinical studies (743 animals) and 14 clinical studies (1527 individuals). Overall, probiotics reduced anxiety-like behavior in animals (Hedges’ g = -0.47, 95% CI -0.77 –-0.16, p = 0.004). Subgroup analyses revealed a significant reduction only among diseased animals. Probiotic species-level analyses identified only Lactobacillus (L.) rhamnosus as an anxiolytic species, but these analyses were broadly under-powered. Probiotics did not significantly reduce symptoms of anxiety in humans (Hedges’ g = -0.12, 95% CI -0.29–0.05, p = 0.151), and did not differentially affect clinical and healthy human samples. Conclusions While preclinical (animal) studies suggest that probiotics may help reduce anxiety, such findings have not yet translated to clinical research in humans, perhaps due to the dearth of extant research with clinically anxious populations. Further investigation of probiotic treatment for clinically relevant anxiety is warranted, particularly with respect to the probiotic species L. rhamnosus

Aerial LiDAR Technology in Support to Avalanches Prevention and Risk Mitigation: AN Operative Application at "colle della Maddalena" (italy)

Abstract. Snow avalanches are the result of unstable snow masses that detach from steep slopes as consequence of changes in snowpack structure. Nowadays, remote sensing technologies can improve the knowledge of avalanches phenomenon. This work focuses on the use of high point density aerial LiDAR (Light Detection And Ranging) technology as support to avalanche events prevention and risk mitigation, by presenting an operative application at Colle della Maddalena (Italy), along the road SS n. 21, nearby the French state border. The area is often involved in intense avalanche events that adversely impact on traffic and freight transport. For this reason, regional administrations will activate the Avalanche Artificial Detachment Intervention Plan (PIDAV, 2012) in order to prevent and manage the avalanche risk in the study area, also adopting artificial detachment systems. Main aim of the present work was to generate high resolution information related to geomorphological characterization (i.e. digital elevation models, slope and aspect) of avalanche sites derived from LiDAR data processing, that will help involved authorities in the management of the avalanche control plan. Digital elevation models at 0.5 m of spatial resolution were generated together with relative tridimensional models. Secondly, a preliminary investigation about capabilities and limits of LiDAR technology was done in the identification of avalanche sites only relying on geomorphological information directly derived by LiDAR data processing. Results showed that position of avalanche sites were correctly identified while no information could be obtained about the extension of the sliding area and identification of detachment areas

Development of light and highly radiation transparent cryostats for FCC detector magnets:First analyses of insulation materials

For both versions of the Future Circular Collider, the electron-positron FCC ee$^+$, requiring a 2 T/4 m bore solenoid for particles spectrometry, and the hadron-hadron FCC hh, CERN is developing an innovative design for the detector solenoids, to enable their positioning inside the calorimeters directly surrounding the inner tracker. For this to happen, the cryostat design has to be optimized to achieve minimum radiation length. The novel design consists of a sandwich of thin inner and outer metallic shells for vacuum tightness, supported by an insulating material with sufficient mechanical resistance paired with lowest thermal conductivity, like Cryogel, a flexible aerogel structure (density 0.16 g/cm$^3$), or glass spheres (e.g. type K1 manufactured by 3M, with 65 μm diameter and density of 0.125 g/cm$^3$). These materials would allow constructing a 4 m bore, 6 m long cryostat with a 250 mm total thickness, a heat load less than 400 W on the cold mass and 10 kW on the thermal shield. In this paper, design options are discussed and methods for qualifying the materials presented

An ex vivo model contributing to the diagnosis and evaluation of new drugs in cystic fibrosis

La fibrosi cistica (FC) è una malattia autosomica recessiva causata da mutazioni nel gene CFTR (Cystic Fibrosis Transmembrane conductance Regulator). Finora sono state descritte circa 2000 mutazioni, ma per la maggior parte di esse è difficile definirne leffetto senza complesse procedure in vitro. Abbiamo effettuato il campionamento (mediante brushing), la cultura e lanalisi di cellule epiteliali nasali umane (HNEC) utilizzando una serie di tecniche che possono aiutare a testare leffetto delle mutazioni CFTR. Abbiamo eseguito 50 brushing da pazienti FC e controlli, e in 45 casi si è ottenuta una coltura positiva. Utilizzando cellule in coltura: i) abbiamo dimostrato lespressione ampiamente eterogenea del CFTR nei pazienti e nei controlli; ii) abbiamo definito leffetto di splicing di una mutazione sul gene CFTR; iii) abbiamo valutato lattività di gating di CFTR in pazienti portatori di differenti mutazioni; iv) abbiamo dimostrato che il butirrato migliora in modo significativo lespressione di CFTR. I dati provenienti dal nostro studio sperimentale dimostrano che luso del modello ex-vivo di cellule epiteliali nasali è un importante e valido strumento di ricerca e di diagnosi nella studio della FC e può anche essere mirato alla sperimentazione ed alla verifica di nuovi farmaci. In definitiva, in base ai nostri dati è possibile esprimere le seguenti conclusioni: 1) il prelievo delle cellule epiteliali nasali mediante brushing è applicabile senza alcuna anestesia ed è ben tollerato da tutti i pazienti affetti da FC (bambini e adulti), è scarsamente invasivo e facilmente ripetibile, è anche in grado di ottenere una sufficiente quantità di HNECs rappresentative, ben conservate, idonee allo studio della funzionalità di CFTR; 2) la conservazione delle cellule prelevate è possibile fino a 48 ore prima che si provveda allallestimento della coltura e ciò permette di avviare studi multicentrici con prelievi in ogni sede e quindi di ottenere una ampia numerosità campionaria; 3) la coltura di cellule epiteliali nasali può essere considerata un modello adatto a studiare leffetto molecolare di nuove mutazioni del gene CFTR e/o mutazioni specifiche di pazienti carriers dal significato incerto; 4) il modello ex-vivo delle HNECs consente inoltre di valutare, prima dellimpiego nelluomo, leffetto di farmaci (potenziatori e/o correttori) sulle cellule di pazienti portatori di mutazioni specifiche di CFTR; tali farmaci possono modulare lespressione genica del canale CFTR aprendo così nuove frontiere terapeutiche e migliori prospettive di vita per pazienti affetti da una patologia cronica come la Fibrosi Cistica; 5) la metodologia da noi istituita risulta essere idonea alla misura quantitativa, mediante fluorescenza, dellattività di gating del canale CFTR presente nelle membrane delle cellule epiteliali nasali prelevate da pazienti portatori di differenti genotipi; in tal modo è possibile individuare: a) pazienti FC portatori di 2 mutazioni gravi con unattività < 10% (in rapporto ai controlli -100%), b) soggetti FC portatori contemporaneamente di una mutazione grave e di una lieve con unattività tra 10-30%, c) i cosiddetti portatori carriers- eterozigoti - con unattività tra 40-70%. In conclusione la possibilità di misurare lattività del canale CFTR in HNECs fornisce un importante contributo alla diagnosi di FC, mediante individuazione di un cut-off diagnostico, ed anche alla previsione della gravità fenotipica della malattia; quindi quanto rilevabile dalla misura del suddetto canale permette di prospettare per il futuro la possibilità di valutare meglio i pazienti per i quali il test del sudore ha dato risultati ambigui (borderline o negativi). La metodica da noi sperimentata consente anche di monitorare i pazienti durante il trattamento farmacologico, valutando in tal modo i reali effetti delle nuove terapie

Rapidly destructive osteoarthritis of the hip joint: a case series

<p>Abstract</p> <p>Background</p> <p>Rapidly destructive arthrosis of the hip is a rare and incompletely understood disorder with scarce literature about variations in natural history within a population.</p> <p>Methods</p> <p>A series of cases from North Wales with rapid progressive joint destruction and extensive subchondral bone loss in the femoral head and acetabulum are presented. Radiographic findings mimicked those of other disorders such as septic arthritis, rheumatoid and seronegative arthritis, primary osteonecrosis with secondary osteoarthritis, or neuropathic osteoarthropathy, but none of the patients had clinical, pathologic, or laboratory evidence of these entities.</p> <p>Results</p> <p>Rapid progression of hip pain and disability was a consistent clinical feature. The average duration of symptoms was 1.4 years. Radiographs obtained at various intervals before surgery (average 14 months) in 18 patients documented rapid hip destruction, involvement being unilateral in 13 cases. All patients underwent total hip arthroplasty, and osteoarthritis was confirmed at pathologic examination.</p> <p>Conclusion</p> <p>The authors postulate that these cases represent an uncommon subset of osteoarthritis and regular review, both clinically and radiologically, are required to assess speed of progression and prevent rapid loss of bone stock without the surgeon being aware. These cases are unsuitable for being placed on long waiting list due to technical difficulties in delayed surgery and compromised outcome following surgery.</p

Outcomes of Patients with Asymptomatic Aortic Stenosis Followed Up in Heart Valve Clinics

Importance: The natural history and the management of patients with asymptomatic aortic stenosis (AS) have not been fully examined in the current era. Objective: To determine the clinical outcomes of patients with asymptomatic AS using data from the Heart Valve Clinic International Database. Design, Setting, and Participants: This registry was assembled by merging data from prospectively gathered institutional databases from 10 heart valve clinics in Europe, Canada, and the United States. Asymptomatic patients with an aortic valve area of 1.5 cm2 or less and preserved left ventricular ejection fraction (LVEF) greater than 50% at entry were considered for the present analysis. Data were collected from January 2001 to December 2014, and data were analyzed from January 2017 to July 2018. Main Outcomes and Measures: Natural history, need for aortic valve replacement (AVR), and survival of asymptomatic patients with moderate or severe AS at entry followed up in a heart valve clinic. Indications for AVR were based on current guideline recommendations. Results: Of the 1375 patients included in this analysis, 834 (60.7%) were male, and the mean (SD) age was 71 (13) years. A total of 861 patients (62.6%) had severe AS (aortic valve area less than 1.0 cm2). The mean (SD) overall survival during medical management (mean [SD] follow up, 27 [24] months) was 93% (1%), 86% (2%), and 75% (4%) at 2, 4, and 8 years, respectively. A total of 104 patients (7.6%) died under observation, including 57 patients (54.8%) from cardiovascular causes. The crude rate of sudden death was 0.65% over the duration of the study. A total of 542 patients (39.4%) underwent AVR, including 388 patients (71.6%) with severe AS at study entry and 154 (28.4%) with moderate AS at entry who progressed to severe AS. Those with severe AS at entry who underwent AVR did so at a mean (SD) of 14.4 (16.6) months and a median of 8.7 months. The mean (SD) 2-year and 4-year AVR-free survival rates for asymptomatic patients with severe AS at baseline were 54% (2%) and 32% (3%), respectively. In those undergoing AVR, the 30-day postprocedural mortality was 0.9%. In patients with severe AS at entry, peak aortic jet velocity (greater than 5 m/s) and LVEF (less than 60%) were associated with all-cause and cardiovascular mortality without AVR; these factors were also associated with postprocedural mortality in those patients with severe AS at baseline who underwent AVR (surgical AVR in 310 patients; transcatheter AVR in 78 patients). Conclusions and Relevance: In patients with asymptomatic AS followed up in heart valve centers, the risk of sudden death is low, and rates of overall survival are similar to those reported from previous series. Patients with severe AS at baseline and peak aortic jet velocity of 5.0 m/s or greater or LVEF less than 60% have increased risks of all-cause and cardiovascular mortality even after AVR. The potential benefit of early intervention should be considered in these high-risk patients
