Age before Beauty: A Comparative Study of Martyrs in American Disaster Movies and Their Medieval Predecessors

A study of a selection of American disaster movies from the past decades reveals the presence of a certain kind of martyr character. These martyrs do not die for their religious or ideological faith but rather in order to save loved ones, sometimes the entire planet. These movie martyrs differ to a great extent from classical Christian martyrs as portrayed in medieval legends. The modern movie martyrs are usually old, and often social outcasts in different ways. Often they have failed as parents, are alcoholics or criminals. Their death is their way of redeeming themselves

Cross-dressing among medieval Ashkenazi Jews: Confirming challenged group borders

This article deals with explicit permissions for two types of cross-dressing found in the thirteenth-century ethical tract Sefer Chasidim. In order to avoid being sexually assaulted, female Jewish travellers were allowed to disguise themselves as a. Christians, even as nuns, or b. men. This contradicts biblical and rabbinical prohibitions against such practices. These textual passages are discussed, set against the Jewish and Christian medieval discourse on dress and identity, and they are also related to other contemporary source texts that show that the borders between men and women, and Jews and Christians, as distinct and separate groups were at this time being contested. The author concludes that these permissions should not be seen as ways of transcending the boundaries of the group, but rather as part of a discourse that served to strengthen such boundaries

Barmhärtiga svenskar och tacksamma flyktingar: Ett beredskapssjukhus sommaren 1945 i svensk press

In June of 1945 Sweden agreed to receive 10 000 former prisoners of German concentration camps for medical care. Approximately 1 200 of these were to be assigned to a temporary hospital in the small Swedish town of Sigtuna. A study of how a selection of Swedish daily papers describe this event shows that the reporters tend to focus more on the Swedish hospital staff than on the refugees. The refugees are merely portrayed as the recipients of Sweden’s humanitarian assistance. In these articles, the refugees have no past and no future. Their role is merely to express their gratitude and to recover, thereby testifying to the efficacy of the Swedish hospital. Life in the hospital in Sigtuna is described as close to paradise. That many of the patients were in such poor condition so that they died shortly after their arrival in Sigtuna is rarely mentioned. These tendencies in the articles about the Sigtuna hospital can be connected to Sweden’s postwar need to redeem its tarnished reputation as a neutral country by portraying itself in public debate as the champion of a humanitarian tradition. It can also be analysed on the basis of what other studies have shown of how Swedish reporters of the 1980s and 1990s constructed an idealistic picture of Sweden and the Swedes by describing immigrants and refugees as the essential Other

Непрямий метод визначення діаграми випромінювання антени з невідомим параболоїдним профілем

Lactobacillus reuteri is a symbiont that inhabits the gastrointestinal (GI) tract of mammals, and several strains are used as probiotics. After introduction of probiotic strains in a complex ecosystem like the GI tract, keeping track of them is a challenge. The main objectives of this study were to introduce reporter proteins that would enable in vivo and in vitro detection of L. reuteri and increase knowledge about its interactions with the host. We describe for the first time cloning of codon-optimized reporter genes encoding click beetle red luciferase (CBRluc) and red fluorescent protein mCherry in L. reuteri strains ATCC PTA 6475 and R2LC. The plasmid persistence of mCherry-expressing lactobacilli was evaluated by both flow cytometry (FCM) and conventional plate count (PC), and the plasmid loss rates measured by FCM were lower overall than those determined by PC. Neutralization of pH and longer induction duration significantly improved the mCherry signal. The persistency, dose-dependent signal intensity and localization of the recombinant bacteria in the GI tract of mice were studied with an in vivo imaging system (IVIS), which allowed us to detect fluorescence from 6475-CBRluc-mCherry given at a dose of 1x10(10) CFU and luminescence signals at doses ranging from 1x10(5) to 1x10(10) CFU. Both 6475-CBRluc-mCherry and R2LC-CBRluc were localized in the colon 1 and 2 h after ingestion, but the majority of the latter were still found in the stomach, possibly reflecting niche specificity for R2LC. Finally, an in vitro experiment showed that mCherry-producing R2LC adhered efficiently to the intra cellular junctions of cultured IPEC-J2 cells. In conclusion, the two reporter genes CBRluc and mCherry were shown to be suitable markers for biophotonic imaging (BPI) of L. reuteri and may provide useful tools for future studies of in vivo and in vitro interactions between the bacteria and the host

Control, anxiety and test performance: Self-reported and physiological indicators of anxiety as mediators

Background: This study investigated the role of different test anxiety components (affective, cognitive, motivational and physiological) as mediators between control and performance as proposed by Pekrun's control-value theory (CVT). While all components were assessed via self-report, the physiological component was additionally assessed via electrodermal activity (EDA). Aims: We examined the relative impact of the self-reported anxiety components and EDA in this mediating mechanism to identify the most relevant assessment(s) (i.e., self-reported anxiety components and/or EDA) for predicting test performance. Sample: The study comprised 50 eighth graders. Methods: Data were collected during a mathematics test comprising six task blocks. State self-reports of control and anxiety components along with test performance and other test emotions were collected block-wise (i.e., repeated assessments within students). EDA was continuously recorded. Results: Consistent with CVT, intra-individual mediation analysis with multiple mediators revealed that higher control predicted lower anxiety (i.e., all self-reported components). Unexpectedly, higher control was associated with increased EDA. Follow-up analyses taking other test emotions into account suggested this might reflect positive activation. Correlations between EDA and control and self-reported anxiety components differed depending on which test emotion was dominant in each situation. Regarding test performance, only the cognitive component was a significant mediator and thus seems to play a pivotal role in the relationship between control and performance. Conclusions: Distinguishing between anxiety components and including unbiased physiological measures improve our understanding of the mechanisms behind the relationship between test anxiety and performance. Higher physiological arousal may be a sign of anxiety but can also be a sign of positive activation. When aiming to reduce negative effects of anxiety on performance, targeting the cognitive component seems crucial. Implications of these findings for educational and psychological practice are discussed

Distinct B cell subsets in Peyer's patches convey probiotic effects by Limosilactobacillus reuteri

Background: Intestinal Peyer's patches (PPs) form unique niches for bacteria-immune cell interactions that direct host immunity and shape the microbiome. Here we investigate how peroral administration of probiotic bacterium Limosilactobacillus reuteri R2LC affects B lymphocytes and IgA induction in the PPs, as well as the downstream consequences on intestinal microbiota and susceptibility to inflammation.Results: The B cells of PPs were separated by size to circumvent activation-dependent cell identification biases due to dynamic expression of markers, which resulted in two phenotypically, transcriptionally, and spatially distinct subsets: small IgD(+)/GL7(-)/S1PR1(+)/Bcl6, CCR6-expressing pre-germinal center (GC)-like B cells with innate-like functions located subepithelially, and large GL7(+)/S1PR1(-)/Ki67(+)/Bcl6, CD69-expressing B cells with strong metabolic activity found in the GC. Peroral L. reuteri administration expanded both B cell subsets and enhanced the innate-like properties of pre-GC-like B cells while retaining them in the sub-epithelial compartment by increased sphingosine-1-phosphate/S1PR1 signaling. Furthermore, L. reuteri promoted GC-like B cell differentiation, which involved expansion of the GC area and autocrine TGF beta-1 activation. Consequently, PD-1-T follicular helper cell-dependent IgA induction and production was increased by L. reuteri, which shifted the intestinal microbiome and protected against dextran-sulfate-sodium induced colitis and dysbiosis.Conclusions: The Peyer's patches sense, enhance and transmit probiotic signals by increasing the numbers and effector functions of distinct B cell subsets, resulting in increased IgA production, altered intestinal microbiota, and protection against inflammation

Does Arterial Hypertension Influence the Onset of Huntington's Disease?

Huntington's disease (HD) age of onset (AO) is mainly determined by the length of the CAG repeat expansion in the huntingtin gene. The remaining AO variability has been attributed to other little-known factors. A factor that has been associated with other neurodegenerative diseases is arterial hypertension (AHT). The aim of this study is to evaluate the contribution of AHT to the AO of HD. We used data from a cohort of 630 European HD patients with adult onset collected by the REGISTRY project of the European Huntington's Disease Network. Multiple linear regression and ANOVA, controlling for the CAG repeat number of the expanded allele (CAGexp) of each patient, were performed to assess the association between the AHT condition and the AO of the motor symptoms (mAO). The results showed a significant association between AHT and mAO, especially when we only considered the patients diagnosed with AHT prior to manifesting any HD signs (pre-HD AHT). Remarkably, despite the low number of cases, those patients developed motor symptoms 5-8 years later than normotensive patients in the most frequent CAGexp range (40-44). AHT is an age related condition and consequently, the age of the patient at the time of data collection could be a confounder variable. However, given that most pre-HD AHT patients included in our study had started treatment with antihypertensive drugs prior to the onset of HD, and that antihypertensive drugs have been suggested to confer a neuroprotective effect in other neurodegenerative diseases, raises the interest in elucidating the impact of AHT and/or AHT treatment in HD age of onset in further studies. A confirmation of our results in a larger sample set would open the possibility to significantly improve HD management.This study was funded by Basque Government Department of Industry grants (Saiotek PE08UN78 and University-Company Program 09+ UEGV096/C01), by the Basque Government Department of Education (IT634-13) and by the University of the Basque Country UPV/EHU (UFI11/20). No funding bodies had any role in study design, data collection and analysis, decision to publish, or preparation of the manuscript
