Die Frauenfelder Fragmente von Konrad Flecks "Flore und Blanscheflur". Zugleich ein Beitrag zur alemannischen Handschriftenüberlieferung des 13. Jahrhunderts

Die heute im Archiv der katholischen Kirchengemeinde Frauenfeld, Schweiz, verwahrten ältesten Fragmente von ,Flore und Blanscheflur' gehören zu den bedeutendsten Zeugen der frühen mittelhochdeutschen Überlieferung. Der Aufsatz bietet eine detaillierte kodikologische, paläographische und dialektologische Untersuchung der in der neueren Forschung vernachlässigten Bruchstücke. Anhand einer genauen Autopsie der erhaltenen Reste können die materiale Struktur der ursprünglichen Vollhandschrift und auch der gestufte Prozess ihrer Makulierung rekonstruiert werden. Als ihr Besitzer im 14. Jahrhundert wird ein Frauenfelder Priester und Pfründstifter, Nikolaus Rüdiger von Messkirch, vermutet. Anlässlich der jeweils nicht eindeutigen Datierung und Lokalisierung der Fragmente werden grundsätzliche Überlegungen zu methodischen Problemen der mediävistischen Handschriftenkunde angestellt. Die Ergebnisse betreffen vor allem zwei Punkte: (1) Layoutmerkmale - im vorliegenden Fall: abgesetzt notierte Verse - sollten bei post quem-Datierungen nicht als Ausschlusskriterium, sondern nur als Indiz herangezogen werden; dabei sollte die Möglichkeit einer direkten Beeinflussung durch französische Vorbilder in Betracht gezogen werden, deren Layoute sich im deutschen Raum im Regelfall erst zeitlich versetzt etablieren. Exemplarisch wird ein bestimmtes Layoutmerkmal der Frauenfelder Fragmente - abgesetzte Verse mit an den rechten Rand gezogenen Reimpunkten - in seiner Belegdichte in der französischen und auch lateinischen Überlieferung seit dem 12. Jahrhundert aufgearbeitet. (2) Bei der Kriterienbildung zur Schriftsprachenbestimmung im Gefolge besonders des ,Historischen südwestdeutschen Sprachatlas' und der auf dem ,Corpus der altdeutschen Originalurkunden' beruhenden Systematisierungen ist für das 13. Jahrhundert zu wenig berücksichtigt worden, dass mit der deutschsprachigen Urkundenüberlieferung das gesamte Belegmaterial erst im letzten Viertel dieses Jahrhunderts einsetzt. Für die erste Hälfte des 13. Jahrhunderts, das die Entwicklung einer neuen literarischen Buchproduktion erlebte und das entsprechende graphematische Wandelerscheinungen erwarten lässt, bilden die daraus gewonnenen Sprachmerkmale keine zuverlässigen Abgrenzungskriterien. Sie sind im Einzelfall zu prüfen, wobei insbesondere im südwestdeutschen Raum aus Gründen des begrenzten Corpus Systematisierungen nur eingeschränkt möglich sind. Exemplarisch werden die Belege eines bestimmten Dialektmerkmals, des sog. ,,ch-Konsonantismus", anhand der gesamten Überlieferung aus dem südwestdeutschen Raum der ersten Jahrhunderthälfte erhoben. Es erweist sich, dass dieses als spezifisch bairisch (ostoberdeutsch) geltende Merkmal auch im alemannischen (westoberdeutschen) Raum für den fraglichen Zeitraum keine Ausnahme bildet. Dabei zeichnen sich Unterschiede in den Schreibungen weltlicher und geistlicher Texte ab.

Effect of multidimensional lifestyle intervention on fitness and adiposity in predominantly migrant preschool children (Ballabeina): cluster randomised controlled trial.

OBJECTIVE: To test the effect of a multidimensional lifestyle intervention on aerobic fitness and adiposity in predominantly migrant preschool children. DESIGN: Cluster randomised controlled single blinded trial (Ballabeina study) over one school year; randomisation was performed after stratification for linguistic region. SETTING: 40 preschool classes in areas with a high migrant population in the German and French speaking regions of Switzerland. PARTICIPANTS: 652 of the 727 preschool children had informed consent and were present for baseline measures (mean age 5.1 years (SD 0.7), 72% migrants of multicultural origins). No children withdrew, but 26 moved away. INTERVENTION: The multidimensional culturally tailored lifestyle intervention included a physical activity programme, lessons on nutrition, media use (use of television and computers), and sleep and adaptation of the built environment of the preschool class. It lasted from August 2008 to June 2009. MAIN OUTCOME MEASURES: Primary outcomes were aerobic fitness (20 m shuttle run test) and body mass index (BMI). Secondary outcomes included motor agility, balance, percentage body fat, waist circumference, physical activity, eating habits, media use, sleep, psychological health, and cognitive abilities. RESULTS: Compared with controls, children in the intervention group had an increase in aerobic fitness at the end of the intervention (adjusted mean difference: 0.32 stages (95% confidence interval 0.07 to 0.57; P=0.01) but no difference in BMI (-0.07 kg/m(2), -0.19 to 0.06; P=0.31). Relative to controls, children in the intervention group had beneficial effects in motor agility (-0.54 s, -0.90 to -0.17; P=0.004), percentage body fat (-1.1%, -2.0 to -0.2; P=0.02), and waist circumference (-1.0 cm, -1.6 to -0.4; P=0.001). There were also significant benefits in the intervention group in reported physical activity, media use, and eating habits, but not in the remaining secondary outcomes. CONCLUSIONS: A multidimensional intervention increased aerobic fitness and reduced body fat but not BMI in predominantly migrant preschool children.

Patient with Fanconi Syndrome (FS) and retinitis pigmentosa (RP) caused by a deletion and duplication of mitochondrial DNA (mtDNA).

BACKGROUND: We report a patient with a highly unusual presentation of a mitochondrial disorder. HISTORY AND SIGNS: An 8-year old girl presented with muscular cramps as well as height and weight deceleration. Investigations revealed lactic acidosis, electrolytic imbalance and urinary loss of glucose and electrolytes secondary to proximal renal tubulopathy consistent with Fanconi syndrome (FS). Ophthalmic examination revealed asymptomatic retinitis pigmentosa (RP) with no other ocular manifestations. A mitochondriopathy was suspected and genetic analysis performed. THERAPY AND OUTCOME: Southern blotting documented a heteroplasmic mutation of mtDNA with deletion/duplication. Three discrete mitochondrial genomes were detected: normal; deletion of 6.7 kb and a deletion/duplication consisting of 1 normal and 1 deleted genome. The relative proportions varied considerably between tissues. CONCLUSIONS: The association of FS and RP combines features of Kearns-Sayre syndrome and Pearson marrow-pancreas syndrome, without being typical of either. This highly unusual clinical presentation emphasises the need for systemic investigation of patients with FS and further underlines the importance of mtDNA analysis in patients with unexpected associations of affected tissues.

Seminoma arising in corrected and uncorrected inguinal cryptorchidism: treatment and prognosis in 66 patients.

PURPOSE: The purpose of this study was to analyze prognosis and treatment results for seminoma arising in corrected and uncorrected inguinal cryptorchidism (SCIC and SUIC). METHODS AND MATERIALS: We reviewed 66 patients with inguinal seminomas between June 1958 and December 1991 at the Cancer Hospital and Institute of Chinese Academy of Medical Sciences. Of these patients, 23 had prior orchiopexy and 43 presented with an inguinal form of cryptorchidism. At presentation, 17 of 66 (26%) patients had nodal metastases. This nodal involvement was 30% (7 of 23) for SCIC and 23% (10 of 43) for SUIC, respectively. These numbers are comparable with those in a series of patients treated for scrotal seminoma at our institution (26% vs. 20%). However, 3 of 23 (13%) patients who had prior orchiopexy presented with inguinal nodal metastasis as compared with 0 of 43 patients with SUIC or 4 of 237 patients with scrotal seminoma (p < .05). There were 49 stage I, 5 stage IIA, 8 stage IIB, 3 stage III, and 1 stage IV patients. All patients underwent radical orchiectomy and received further radiotherapy, chemotherapy, or both. Patients with stage I and stage II disease were treated primarily with radiotherapy, whereas patients with stage III and IV disease were treated with chemotherapy. RESULTS: The overall and disease-free survival at 5 and 10 years was 94% and 92%, 89% and 87%, respectively. The overall 5- and 10-year survival by stage was 100% and 100% for stage I, and 77% and 68% for stage II, respectively (p < .05). There was no significant difference in survival between SUIC and SCIC (93% vs. 96% at 5 years). Four patients developed relapse. Two of these four patients experienced relapse at the inguinal area, due to a marginal miss. Three of four patients with relapse were successfully salvaged, and one died of disease. CONCLUSION: Our results indicate that prognosis for inguinal seminoma is excellent and similar to that of scrotal seminoma. Postorchiectomy radiotherapy can be considered as the standard treatment for stage I and IIA inguinal seminoma. We recommend routinely including the para-aortic and ipsilateral pelvic nodes.

An overview of the metabolic differences between Bradyrhizobium japonicum 110 bacteria and differentiated bacteroids from soybean (Glycine max) root nodules: an in vitro 13C- and 31P-nuclear magnetic resonance spectroscopy study.

Bradyrhizobium japonicum is a symbiotic nitrogen-fixing soil bacteria that induce root nodules formation in legume soybean (Glycine max.). Using (13)C- and (31)P-nuclear magnetic resonance (NMR) spectroscopy, we have analysed the metabolite profiles of cultivated B. japonicum cells and bacteroids isolated from soybean nodules. Our results revealed some quantitative and qualitative differences between the metabolite profiles of bacteroids and their vegetative state. This includes in bacteroids a huge accumulation of soluble carbohydrates such as trehalose, glutamate, myo-inositol and homospermidine as well as Pi, nucleotide pools and intermediates of the primary carbon metabolism. Using this novel approach, these data show that most of the compounds detected in bacteroids reflect the metabolic adaptation of rhizobia to the surrounding microenvironment with its host plant cells.

Sensitivity of single-voxel 1H-MRS in investigating the metabolism of the activated human visual cortex at 7 T.

Proton magnetic resonance spectroscopy (1H-MRS) has been used in a number of studies to noninvasively assess the temporal changes of lactate in the activated human brain. However, the results have not been consistent. The aim of the present study was to test the sensitivity of 1H-MRS during functional experiments at the highest magnetic field currently available for human studies (7 T). Stability and reproducibility of the measurements were evaluated from LCModel analysis of time series of spectra measured during a visual stimulation paradigm and by examination of the difference between spectra obtained at rest and during activation. The sensitivity threshold to detect concentration changes was 0.2 micromol/g for most of the quantified metabolites. The possible variations of metabolite concentrations during visual stimulation were within the same range (+/-0.2 micromol/g). In addition, the influence of a small line-narrowing effect due to the blood oxygenation level-dependent (BOLD) T2* changes on the estimated concentrations was simulated. Quantification of metabolites was, in general, not affected beyond 1% by line-width changes within 0.5 Hz.

Évaluation de la perfusion myocardique par TEP-TDM. [Myocardial perfusion imaging using PET/CT.]

For the past decade, PET and PET/CT have been widely studied for myocardial perfusion imaging. Several studies demonstrated the incremental value of PET for the diagnostic and prognostic assessment of patients with coronary artery disease. Moreover, PET allows for non-invasively quantifying myocardial blood flow and myocardial flow reserve, that both are recognized as surrogate marker of cardiac event free survival. By enabling the exploration of epicardial disease and the microvasculature, PET constitutes a unique tool to study pathophysiogical mechanisms leading to atherosclerosis genesis. The recent emergence of high-tech hybrid machines may even provide further incremental information about coronary function and morphology. By taking the best of each modality, a better assessment of patients with coronary artery disease is expected. (C) 2011 Elsevier Masson SAS. All rights reserved.

Hour of birth as a prognostic factor for perinatal death.

The analysis of the 220,540 births and 2152 perinatal deaths recorded in Switzerland between 1979 and 1981 showed a variation of perinatal mortality rates (PMR) according to the hour of birth. The PMR for babies born between 4 pm and 2 am was 12 per 1000, contrasting with a figure of 8.4 per 1000 for babies born between 2 am and 4 pm. This pattern, which was fairly constant throughout the week, was characterised by a slow and steady increase from the very early morning, reaching a maximum in the late evening. There was also an hour-to-hour variation in the proportion of babies born weighing less than 2500 g, with a maximum in the evening and a less pronounced peak in the morning: the mortality rates by birthweight were raised only in the evening. Since the availability of hospital staff and equipment also follows a circadian rhythm, the variation in PMR may be related to a circadian rhythm of quality of care or possibly to chronobiological or selection factors.

Can Charisma Be Taught? Tests of Two Interventions

We tested whether we could teach individuals to behave more charismatically, andwhether changes in charisma affected leader outcomes. In Study 1, a mixed-design fieldexperiment, we randomly assigned 34 middle-level managers to a control or anexperimental group. Three months later, we reassessed the managers using theircoworker ratings (Time 1 raters = 343; Time 2 raters = 321). In Study 2, a within-subjectslaboratory experiment, we videotaped 41 MBA participants giving a speech. We thentaught them how to behave more charismatically, and they redelivered the speech6 weeks later. Independent assessors (n = 135) rated the speeches. Results from thestudies indicated that the training had significant effects on ratings of leader charisma(mean D = .62) and that charisma had significant effects on ratings of leaderprototypicality and emergence................................................................................................................................

"Il faut bien que jeunesse se fasse !" : ethnographie d'une société de jeunesse campagnarde

Folklorisée ou stigmatisée, la jeunesse des mondes ruraux est l'objet de discours qui correspondent rarement au vécu des personnes concernées. Elle serait soit la garante des traditions passées et des liens intergénérationnels, soit animée par l'esprit festif, par une culture machiste et par la défense d'une identité paysanne et patriotique, plus encline à se replier sur des valeurs conservatrices qu'à témoigner de positions et d'attitudes progressistes. Face à ces idées reçues, Alexandre Dafflon tente dans cet ouvrage de comprendre qui sont ces jeunes, ce qu'ils et elles font et les logiques qui animent leurs conduites. A partir d'une enquête ethnographique auprès de membres d'une société de jeunesse campagnarde en Suisse, l'auteur retrace les parcours de vie et les effets que produisent les expériences quotidiennes, intimes et collectives sur les façons de voir, de sentir et d'agir. Il montre qu'au cours de leur engagement, les jeunes aménagent leurs acquis antérieurs et construisent de nouveaux savoir-faire et savoir-être. Ils et elles apprennent également à conserver une langue commune, constitutive du milieu auquel ils ou elles estiment appartenir et dont la diversité des espaces côtoyés les éloignent toujours plus. En insistant sur l'hétérogénéité des histoires de vie et sur les mécanismes par lesquels les jeunes font et sont fait-e-s par la société de jeunesse, Alexandre Dafflon apporte aux études de socialisation un éclairage stimulant. Alexandre Dafflon est sociologue, rattaché au Centre de Recherche sur l'Action Politique de l'Université de Lausanne (CRAPUL-IEPI) et au Centre européen de sociologie et de science politique (CNRS-EHESS-Paris I). Il étudie les sociabilités juvéniles en milieu rural.

Role of Chlamydia trachomatis and emerging Chlamydia-related bacteria in ectopic pregnancy in Vietnam.

In this case-control study, we investigated the seroprevalence and molecular evidence of Chlamydia trachomatis and Waddlia chondrophila in ectopic pregnancies (EP) and uneventful control pregnancies in 343 women from Vietnam. Whereas presence of C. trachomatis IgG was strongly associated with EP [adjusted odds ratio (aOR) 5·41, 95% confidence interval (CI) 2·58-11·32], its DNA remained undetected in all tubal lesions. We confirmed an independent association between antibodies against Waddlia and previous miscarriage (aOR 1·87, 95% CI 1·02-3·42). Further investigations are needed to understand the clinical significance of Waddlia's high seroprevalence (25·9% in control pregnancies) in this urban population.
