Rediscovery and Canonization: The Roman Classics in the Middle Ages

Issue 3 of Interfaces: A Journal of Medieval European Literatures explores the theme of the rediscovery and canonization of the Roman classics in medieval Western European literary culture, beginning in the eleventh century and reaching a wide impact on literary and intellectual life in the twelfth century. It is headed by an article by Birger Munk Olsen whose immense and comprehensive work of cataloguing and analyzing the entire record of manuscripts containing Roman classics copied before 1200 is nearing completion (L‘étude des auteurs classiques aux XIe et XIIe siècles, 5 vols). Within our journal’s scope of medieval European literature we have found it both rewarding and fitting to take Munk Olsen’s work as a prism for what is a striking literary phenomenon across most geographies and chronologies of medieval Europe: the engagement with the pre-Christian classics.The catalogue and the synthesis by Munk Olsen put many kinds of new studies on a firm footing. In this issue of Interfaces we present three 'frontiers' or types of scholarship on the rediscovery and canonization of the Roman classics all taking their cue from the meticulous way L’étude has charted out this territory

A westernized diet changed the colonic bacterial composition and metabolite concentration in a dextran sulfate sodium pig model for ulcerative colitis

IntroductionUlcerative colitis (UC) is characterized by chronic inflammation in the colonic epithelium and has a blurred etiology. A western diet and microbial dysbiosis in the colon were reported to play a role in UC development. In this study, we investigated the effect of a westernized diet, i.e., increasing fat and protein content by including ground beef, on the colonic bacterial composition in a dextran sulfate sodium (DexSS) challenged pig study.MethodsThe experiment was carried out in three complete blocks following a 2×2 factorial design including 24 six-week old pigs, fed either a standard diet (CT) or the standard diet substituted with 15% ground beef to simulate a typical westernized diet (WD). Colitis was induced in half of the pigs on each dietary treatment by oral administration of DexSS (DSS and WD+DSS, respectively). Samples from proximal and distal colon and feces were collected.Results and discussionBacterial alpha diversity was unaffected by experimental block, and sample type. In proximal colon, WD group had similar alpha diversity to CT group and the WD+DSS group showed the lowest alpha diversity compared to the other treatment groups. There was a significant interaction between western diet and DexSS for beta diversity, based on Bray-Curtis dissimilarly. The westernized diet and DexSS resulted in three and seven differentially abundant phyla, 21 and 65 species, respectively, mainly associated with the Firmicutes and Bacteroidota phyla followed by Spirochaetota, Desulfobacterota, and Proteobacteria. The concentration of short-chain fatty acids (SCFA) was lowest in the distal colon. Treatment had a slight effect on the estimates for microbial metabolites that might have valuable biological relevance for future studies. The concentration of putrescine in the colon and feces and that of total biogenic amines was highest in the WD+DSS group. We conclude that a westernized diet could be a potential risk factor and an exacerbating agent for UC by reducing the abundance of SCFA-producing bacteria, increasing the abundance of pathogens such as Helicobacter trogontum, and by increasing the concentration of microbial proteolytic-derived metabolites in the colon

Autonomous Meridian Sensory Response: from Internet subculture to audiovisual therapy

ASMR (Autonomous Sensory Meridian Response) is the name given to a pleasant sensation that can be felt most commonly on the scalp and can be triggered by various gentle sounds (like whispers, crinkles or tapping), smooth and repetitive visual stimuli, personal attention (like the touch of a hairdresser or a masseur) or other events. ASMR is often associated with a general feeling of relaxation and peace. Whilst academic research on the sociological, artistic, sensory and cognitive dimensions is still in its infancy ASMR has grown into a worldwide, cross-disciplinary, inter-cultural, multi-lingual social media sensation. This paper outlines the rise of ASMR as Internet subculture from its inception as ‘whispering community’ on Internet platforms and blogs, to become a truly popular (i.e. made by the people) platform for creative expression, self-made holistic therapy and in some instances true artistic audiovisual endeavours. This paper comments on the reasons behind the rise of the ASMR community as a fertile ground for creative expression. Audiences’ expectations are dictated by the attention-induced nature of the sensory experience, a factor that spawned an exceptionally perceptive viewership if one considers the inherently fragmented essence of ubiquitous streaming media and the impatient scanning and skipping modes of reception it encourages. ‘ASMRtists’ thus enjoy a privileged relationship with audiences who are not impressed with the relentless pour of energy and information from social media platforms and treasure, instead, the slow, the quiet and the subtle. Examples from various ASMR content creators will be analysed from the compositional standpoint, highlighting technical and idiomatic similarities with forms of improvisatory practices and experimental artistic languages such as Musique Concrète. The paper will also illustrate recent audiovisual projects related to ASMR carried out at Keele University and will introduce the audience to planned developments towards ASMR related content delivered through mobile platforms

More Than Smell - COVID-19 Is Associated With Severe Impairment of Smell,Taste, and Chemesthesis

Recent anecdotal and scientific reports have provided evidence of a link between COVID-19 and chemosensory impairments, such as anosmia. However, these reports have downplayed or failed to distinguish potential effects on taste, ignored chemesthesis, and generally lacked quantitative measurements. Here, we report the development, implementation, and initial results of a multilingual, international questionnaire to assess self-reported quantity and quality of perception in 3 distinct chemosensory modalities (smell, taste, and chemesthesis) before and during COVID-19. In the first 11 days after questionnaire launch, 4039 participants (2913 women, 1118 men, and 8 others, aged 19-79) reported a COVID-19 diagnosis either via laboratory tests or clinical assessment. Importantly, smell, taste, and chemesthetic function were each significantly reduced compared to their status before the disease. Difference scores (maximum possible change +/- 100) revealed a mean reduction of smell (-79.7 +/- 28.7, mean +/- standard deviation), taste (-69.0 +/- 32.6), and chemesthetic (-37.3 +/- 36.2) function during COVID-19. Qualitative changes in olfactory ability (parosmia and phantosmia) were relatively rare and correlated with smell loss. Importantly, perceived nasal obstruction did not account for smell loss. Furthermore, chemosensory impairments were similar between participants in the laboratory test and clinical assessment groups. These results show that COVID-19-associated chemosensory impairment is not limited to smell but also affects taste and chemesthesis.The multimodal impact of COVID-19 and the lack of perceived nasal obstruction suggest that severe acute respiratory syndrome coronavirus strain 2 (SARS-CoV-2) infection may disrupt sensory-neural mechanisms

Mindfulness and autonomous sensory meridian response (ASMR)

Background Autonomous sensory meridian response (ASMR) is a perceptual phenomenon in which specific audiovisual stimuli frequently elicit tingling sensations on the scalp and neck. These stimuli (“ASMR triggers”) are typically social in nature (e.g., watching someone brush their hair, hearing whispering,) and often elicit a calm and positive emotional state that may last up to several minutes. ASMR experiences phenomenologically overlap with mindfulness; however, no research has directly examined how mindfulness might relate to ASMR. Methods In the current study, 284 individuals with ASMR completed the Toronto Mindfulness Scale (TMS), the Mindful Attention and Awareness Scale (MAAS), and a questionnaire examining ASMR experiences. Age- and sex-matched control participants were asked to view two ASMR-eliciting videos to ensure that they did not experience tingling sensations associated with ASMR; they then completed the TMS and MAAS questionnaires. Results When compared with matched controls, individuals with ASMR generated significantly higher scores on the MAAS, a global measure of mindfulness, as well as significantly higher scores on the Curiosity subscale of the TMS. Conclusions These results suggest that the sensory-emotional experiences associated with ASMR may be partially explained by a distinct subset of characteristics associated with mindfulness

Rapid antimicrobial susceptibility testing of clinical isolates by digital time-lapse microscopy

Rapid antimicrobial susceptibility testing (AST) is essential for early and appropriate therapy. Methods with short detection time enabling same-day treatment optimisation are highly favourable. In this study, we evaluated the potential of a digital time-lapse microscope system, the oCelloScope system, to perform rapid AST. The oCelloScope system demonstrated a very high accuracy (96 % overall agreement) when determining the resistance profiles of four reference strains, nine clinical isolates, including multi-drug-resistant isolates, and three positive blood cultures. AST of clinical isolates (168 antimicrobial agent–organism combinations) demonstrated 3.6 % minor, no major and 1.2 % very major errors of the oCelloScope system compared to conventional susceptibility testing, as well as a rapid and correct phenotypic detection of strains with methicillin-resistant Staphylococcus aureus (MRSA) and extended-spectrum β-lactamase (ESBL) profiles. The net average time-to-result was 108 min, with 95 % of the results being available within 180 min. In conclusion, this study strongly indicates that the oCelloScope system holds considerable potential as an accurate and sensitive AST method with short time-to-result, enabling same-day targeted antimicrobial therapy, facilitating antibiotic stewardship and better patient management. A full-scale validation of the oCelloScope system including more isolates is necessary to assess the impact of using it for AST
