Earliest expansion of animal husbandry beyond the Mediterranean zone in the sixth millennium BC
(2017)
Since their domestication in the Mediterranean zone of Southwest Asia in the eighth millennium BC, sheep, goats, pigs and cattle have been remarkably successful in colonizing a broad variety of environments. The initial steps in this process can be traced back to the dispersal of farming groups into the interior of the Balkans in the early sixth millennium BC, who were the first to introduce Mediterranean livestock beyond its natural climatic range. Here, we combine analysis of biomolecular and isotopic compositions of lipids preserved in prehistoric pottery with faunal analyses of taxonomic composition from the earliest farming sites in southeast Europe to reconstruct this pivotal event in the early history of animal husbandry. We observe a marked divergence between the (sub)Mediterranean and temperate regions of Southeast Europe, and in particular a significant increase of dairying in the biochemical record coupled with a shift to cattle and wild fauna at most sites north of the Balkan mountain range. The findings strongly suggest that dairying was crucial for the expansion of the earliest farming system beyond its native bioclimatic zone.
Unequivocal international guidelines regarding the diagnosis and management of patients with acute appendicitis are lacking. The aim of the consensus meeting 2015 of the EAES was to generate a European guideline based on best available evidence and expert opinions of a panel of EAES members. After a systematic review of the literature by an international group of surgical research fellows, an expert panel with extensive clinical experience in the management of appendicitis discussed statements and recommendations. Statements and recommendations with more than 70 % agreement by the experts were selected for a web survey and the consensus meeting of the EAES in Bucharest in June 2015. EAES members and attendees at the EAES meeting in Bucharest could vote on these statements and recommendations. In the case of more than 70 % agreement, the statement or recommendation was defined as supported by the scientific community. Results from both the web survey and the consensus meeting in Bucharest are presented as percentages. In total, 46 statements and recommendations were selected for the web survey and consensus meeting. More than 232 members and attendees voted on them. In 41 of 46 statements and recommendations, more than 70 % agreement was reached. All 46 statements and recommendations are presented in this paper. They comprise topics regarding the diagnostic work-up, treatment indications, procedural aspects and post-operative care. The consensus meeting produced 46 statements and recommendations on the diagnostic work-up and management of appendicitis. The majority of the EAES members supported these statements. These consensus proceedings provide additional guidance to surgeons and surgical residents providing care to patients with appendicitis.
Background: Only few authors have analyzed the impact of workplace conflicts and the resulting stress on the risk of developing cardiovascular disorders. The goal of this study was to analyze the association between workplace conflicts and cardiovascular disorders in patients treated by German general practitioners.
Methods: Patients with an initial documentation of a workplace conflict experience between 2005 and 2014 were identified in 699 general practitioner practices (index date). We included only those who were between the ages of 18 and 65 years, had a follow-up time of at least 180 days after the index date, and had not been diagnosed with angina pectoris, myocardial infarction, coronary heart diseases, or stroke prior to the documentation of the workplace mobbing. In total, the study population consisted of 7,374 patients who experienced conflicts and 7,374 controls for analysis. The main outcome measure was the incidence of angina pectoris, myocardial infarction, and stroke correlated with workplace conflict experiences.
Results: After a maximum of five years of follow-up, 2.9% of individuals who experienced workplace conflict were affected by cardiovascular diseases, while only 1.4% were affected in the control group (p-value <0.001). Workplace conflict was associated with a 1.63-fold increase in the risk of developing cardiovascular diseases. Finally, the impact of workplace conflict was higher for myocardial infarction (OR=2.03) than for angina pectoris (OR=1.79) and stroke (OR=1.56).
Conclusions: Overall, we found a significant association between workplace conflicts and cardiovascular disorders.
Body image dissatisfaction is a serious, global problem that negatively affects life satisfaction. Several claims have been made about the possible psychological benefits of naturist activities, but very little empirical research has investigated these benefits or any plausible explanations for them. In three studies—one large-scale, cross-sectional study (n = 849), and 2 prospective studies (n = 24, n = 100) this research developed and applied knowledge about the possible benefits of naturist activities. It was found that more participation in naturist activities predicted greater life satisfaction—a relationship that was mediated by more positive body image, and higher self-esteem (Study 1). Applying these findings, it was found that participation in actual naturist activities led to an increase in life satisfaction, an effect that was also mediated by improvements in body image and self-esteem (Studies 2 and 3). The potential benefits of naturism are discussed, as well as possible future research, and implications for the use of naturist activities.
In evidence-based weight-loss programs weight regain is common after an initial weight reduction. Eating slowly significantly lowers meal energy intake and hunger ratings. Despite this knowledge, obese individuals do not implement this behaviour. We, thus tested the hypothesis of changing eating behaviour with an intra-oral medical device leading to constant weight reduction in overweight and obesity.
Six obese patients (6 men, age 56 ± 14, BMI 29 ± 2 kg / m2) with increased CVRF profile were included in this prospective study. All patients had been treated for obesity during the last 10 years in a single centre and had at least 3 frustrate evidence-based diets. Patients received a novel non-invasive intra-oral medical device to slow eating time. Further advice included not to count calories, to avoid any other form of diet, to take their time with their meals, and to eat whatever they liked.
This device was used only during meals for the first 4 to 8 weeks for a total of 88 [20–160] hours. Follow-up period was 23 [15–38] months. During this period, patients lost 11% [5–20%] (p<0.001) of their initial weight. At 12 months, all patients had lost >5%, and 67% (4/6) achieved a >10% bodyweight loss. In the course of the study, altered eating patterns were observed. There were no complications with the medical device. Of note, all patients continued to lose weight after the initial intervention period (p<0.001) and none of them had weight regain.
With this medical device, overweight and obese patients with a history of previously frustrating attempts to lose weight achieved a significant and sustained weight loss over two years. These results warrant the ongoing prospective randomised controlled trial to prove concept and mechanism of action.
Decreased STARD10 expression is associated with defective insulin secretion in humans and mice
(2017)
Genetic variants near ARAP1 (CENTD2) and STARD10 influence type 2 diabetes (T2D) risk. The risk alleles impair glucose-induced insulin secretion and, paradoxically but characteristically, are associated with decreased proinsulin:insulin ratios, indicating improved proinsulin conversion. Neither the identity of the causal variants nor the gene(s) through which risk is conferred have been firmly established. Whereas ARAP1 encodes a GTPase activating protein, STARD10 is a member of the steroidogenic acute regulatory protein (StAR)-related lipid transfer protein family. By integrating genetic fine-mapping and epigenomic annotation data and performing promoter-reporter and chromatin conformational capture (3C) studies in β cell lines, we localize the causal variant(s) at this locus to a 5 kb region that overlaps a stretch-enhancer active in islets. This region contains several highly correlated T2D-risk variants, including the rs140130268 indel. Expression QTL analysis of islet transcriptomes from three independent subject groups demonstrated that T2D-risk allele carriers displayed reduced levels of STARD10 mRNA, with no concomitant change in ARAP1 mRNA levels. Correspondingly, β-cell-selective deletion of StarD10 in mice led to impaired glucose-stimulated Ca2+ dynamics and insulin secretion and recapitulated the pattern of improved proinsulin processing observed at the human GWAS signal. Conversely, overexpression of StarD10 in the adult β cell improved glucose tolerance in high fat-fed animals. In contrast, manipulation of Arap1 in β cells had no impact on insulin secretion or proinsulin conversion in mice. This convergence of human and murine data provides compelling evidence that the T2D risk associated with variation at this locus is mediated through reduction in STARD10 expression in the β cell.
The article consists in a comparative reading of three novels: Um rio chamado tempo by Mia Couto, Le pain des corbeaux by Lhoussain Azergui and Paw królowej by Dorota Masłowska. In spite of the difference of the historical circumstances of Mozambique, Morocco and Poland, these three books meet at an intersecting point: the emergence of an intelligentsia that uses literacy and writing as an instrument to deconstruct the post-colonial concept of nation and to operate a trans-colonial renegotiation of identity. By the notion of trans-colonial, I understand the opposition against new kinds of symbolic violence that emerged after the end of the colonial period; here this new form of oppression is related to the concept of national unity – an artificial construct that leaves no place for a dualism or pluralism of cultural reality (two shores of the Zambezi river, Arab and Berber dualism in Morocco, "small homelands" in Poland).
The young heroes of the novels grasp the pen in order to break through the falseness or the taboos created by the fathers, establishing, at the same time, the relation of solidarity with the world of the grandfathers. The act of writing becomes an actualization of the ancestral universe of magic. The settlement of accounts with the parental generation concerns the vision of nation built upon the resistance against the colonizer (it also refers to the Polish cultural formation, based on the tradition of uprisings and resistance against the Russians).
A three-dimensional gridded climatology of carbon monoxide (CO) has been developed by trajectory mapping of global MOZAIC-IAGOS in situ measurements from commercial aircraft data. CO measurements made during aircraft ascent and descent, comprising nearly 41 200 profiles at 148 airports worldwide from December 2001 to December 2012, are used. Forward and backward trajectories are calculated from meteorological reanalysis data in order to map the CO measurements to other locations and so to fill in the spatial domain. This domain-filling technique employs 15 800 000 calculated trajectories to map otherwise sparse MOZAIC-IAGOS data into a quasi-global field. The resulting trajectory-mapped CO data set is archived monthly from 2001 to 2012 on a grid of 5° longitude × 5° latitude × 1 km altitude, from the surface to 14 km altitude.
The mapping product has been carefully evaluated, firstly by comparing maps constructed using only forward trajectories and using only backward trajectories. The two methods show similar global CO distribution patterns. The magnitude of their differences is most commonly 10 % or less and found to be less than 30 % for almost all cases. Secondly, the method has been validated by comparing profiles for individual airports with those produced by the mapping method when data from that site are excluded. While there are larger differences below 2 km, the two methods agree very well between 2 and 10 km with the magnitude of biases within 20 %. Finally, the mapping product is compared with global MOZAIC-IAGOS cruise-level data, which were not included in the trajectory-mapped data set, and with independent data from the NOAA aircraft flask sampling program. The trajectory-mapped MOZAIC-IAGOS CO values show generally good agreement with both independent data sets.
Maps are also compared with version 6 data from the Measurements Of Pollution In The Troposphere (MOPITT) satellite instrument. Both data sets clearly show major regional CO sources such as biomass burning in Central and southern Africa and anthropogenic emissions in eastern China. While the maps show similar features and patterns, and relative biases are small in the lowermost troposphere, we find differences of ∼ 20 % in CO volume mixing ratios between 500 and 300 hPa. These upper-tropospheric biases are not related to the mapping procedure, as almost identical differences are found with the original in situ MOZAIC-IAGOS data. The total CO trajectory-mapped MOZAIC-IAGOS column is also higher than the MOPITT CO total column by 12–16 %.
The data set shows the seasonal CO cycle over different latitude bands and altitude ranges as well as long-term trends over different latitude bands. We observe a decline in CO over the northern hemispheric extratropics and the tropics consistent with that reported by previous studies using other data sources.
We anticipate use of the trajectory-mapped MOZAIC-IAGOS CO data set as an a priori climatology for satellite retrieval and for air quality model validation and initialization.

The maps clearly show major regional CO sources such as biomass burning in the central and southern Africa and anthropogenic emissions in eastern China. The dataset shows the seasonal CO cycle over different latitude bands and altitude ranges that are representative of the regions as well as long-term trends over latitude bands. We observe a decline in CO over the Northern Hemisphere extratropics and the tropics consistent with that reported by previous studies.
Similar maps have been made using the concurrent O3 measurements by MOZAICIAGOS, as the global variation of O3–CO correlations can be a useful tool for the evaluation of ozone sources and transport in chemical transport models. We anticipate use of the trajectory-mapped MOZAIC-IAGOS CO dataset as an a priori climatology for satellite retrieval, and for air quality model validation and initialization.
The first step in methanol metabolism in methylotrophic yeasts, the oxidation of methanol and higher alcohols with molecular oxygen to formaldehyde and hydrogen peroxide, is catalysed by alcohol oxidase (AOX), a 600-kDa homo-octamer containing eight FAD cofactors. When these yeasts are grown with methanol as the carbon source, AOX forms large crystalline arrays in peroxisomes. We determined the structure of AOX by cryo-electron microscopy at a resolution of 3.4 Å. All residues of the 662-amino acid polypeptide as well as the FAD are well resolved. AOX shows high structural homology to other members of the GMC family of oxidoreductases, which share a conserved FAD binding domain, but have different substrate specificities. The preference of AOX for small alcohols is explained by the presence of conserved bulky aromatic residues near the active site. Compared to the other GMC enzymes, AOX contains a large number of amino acid inserts, the longest being 75 residues. These segments are found at the periphery of the monomer and make extensive inter-subunit contacts which are responsible for the very stable octamer. A short surface helix forms contacts between two octamers, explaining the tendency of AOX to form crystals in the peroxisomes.
Advantageous fragmentation? : reimagining metropolitan governance and spatial planning in Rhine-Main
(2006)
This paper traces the latest round of debates about appropriate scales and scopes of government and governance in Rhine-Main - an economically highly integrated but politically, territorially and emotionally divided region. We identify a downscaling of political power from the regional to the municipal level, and an upscaling of informal networking and image building to an extended regional scale. These countertrends are signs of a more complex geographical rearrangement in municipal and institutional relations. The inherent contradictions in the rescaling and reimagining of Rhine-Main are evident in the Strategic Vision for Frankfurt/Rhein-Main 2020. Its new conceptualization of Rhine-Main postulates complementary polycentricity as a competitive asset but remains firmly grounded in an institutional territorial logic that contravenes its own economically-driven agenda.
Unter der Signatur VI/273 befinden sich in der Stiftsbibliothek Kremsmünster acht Pergamentstreifen unterschiedlicher Breite (...) und unregelmäßiger Länge (...). Es handelt sich um die Reste von zwei Pergamentdoppelblättern (...). Die Schrift gehört wohl noch dem 12. Jahrhundert an, sie macht jedenfalls einen altertümlicheren Eindruck als die der Göttinger Bruchstücke, der bisher ältesten Überlieferung des Lucidarius (...). Inhaltlich erweist sich die vorliegende Textpartie zugehörig zum 3. Buch des Lucidarius (...).
Die Annahme, Fuß sei ein Minnesänger gewesen, beruht auf der Zuordnung zu drei Personen, die auf diesem Gebiet hervorgetreten sind, und auf der Interpretation der Bezeichnung ‚puler’. Trifft nun schon die Angabe „Minnesänger“ bei Wolfram nur für ein dem späten Mittelalter kaum mehr gegenwärtiges Nebengebiet seines dichterischen Schaffens zu, so bedeutet ‚puler’ in den (...) [Volker Mertens] bekannten Belegen soviel wie „Minner, Liebhaber“, in einem Fall auch „Sachverständiger in Liebesdingen“ (...), aber niemals „Minnesänger“.
Die Papier-Hs. B II, 1 der Fürstlich Fürstenbergischen Bibliothek Donaueschingen enthält die Postille des Hartung/Heinrich von Erfurt (…). Sie wurde laut Schreiberkolophon f. 320v i.J. 1451 geschrieben. (…) Abschließend (…) [gibt Volker Mertens] eine Konkordanz der Überlieferung der Postille. Sie enthält den liturgischen Ort, bzw. das Textwort und für die Hss. Z, F, D, K und R die laufende Nummer und die jeweilige Seitenangabe, ausgerichtet an Z, weil diese Hs. in der Anordnung am zuverlässigsten ist.
Groß ist die Spannweite der Interpretationen, die die ersten Verse von Hartmanns 'Iwein' erfahren haben. (…) Das reicht vom „Inbegriff der güete..., bei dem caritas, misericordia und summum bonum mitgedacht werden müssen“ (…) bis zum „recht verstandenen Rittertum“ (…), die als „leitstern“ (…) des Gedichts fungieren; kürzlich hat D.G. MOWATT den Prolog sogar ironisch verstehen wollen (…), wobei beweiskräftige sprachliche Signale für uneigentliches Sprechen jedoch kaum auffindbar sein dürften (…) und die Annahme einer nachträglichen Ironisierung des Beginns durch das (einseitig interpretierte) Ende des Roman nur aus der vergleichenden Lektüre des modernen Interpreten, nicht aber aus einer kontinuierlich-linearen zuhörenden Aufnahme durch Hartmanns Publikum abgeleitet werden kann.
„Unter unsern Altdeutschen Gedichten wenigstens wüßte ich kein Paar zu nennen, das uns mit einer solchen Familienähnlichkeit überraschte wie der Iwein und Wigalois“, schreibt G. F. Benecke in der Einleitung seiner Wigalois-Ausgabe (S. XV). (…) Als vermittelnde Kategorie zwischen der literarischen Gestaltung der historischen Realität (sowohl auf der Produktions- wie der Rezeptionsseite) (…) [benutzt Volker Mertens] im Folgenden die Konzeption der „Lebensform“ (…): der erzählerisch mit wichtigen Signalen angedeuteten Lebenssituationen, des Handlungsrahmens und der Vorstellungen der Personen können die Zuhörer Selbst- oder Fremdidentifikationen entnehmen und so die erzählte Geschichte als Antwort auf die Aussage zu einer bestimmten historischen Situation verstehen.
Alte Themen, auch unter neuen Vorzeichen nachspielbar [Volker Mertens fragt] nach ihrer Realisierbarkeit im höfischen Tristanroman des späten 12. und frühen 13. Jahrhundert, wie er von den beiden unvollständigen Werken des Thomas von Britannien und Gottfrieds von Straßburg repräsentiert wird. (…) Drei Szenen (…) [greift er heraus]: Tristans Pygmalion-Situation im Bildersaal, die allegorische Liebesapotheose der Minnegrotte und den mythischen liebebegründenden Trank.
New Philology: Das ist zunächst ein Schlagwort gegenwärtiger mediävistischer Methodendiskussion, und fast möchte man meinen, es hätte noch prägnanter formuliert werden können, wenn man etwas auf eine Bildung in Analogie zu anderen kurrenten ‚New-isms’ – New Medievalism (…) oder New Historicism (…) etwa – verfallen wäre: ‚New Philologism’. (…) Als Interdependenz (…) [einer] relativ situationsabstrakten ‚Formiertheit’ der poetischen Rede und der spezifischen situationellen variance des Textes (…) müsste man die soziale, also kommunikative Logik des mittelalterlichen Textes rekonstruieren können. Dabei dürfte dann auch sichtbar werden, daß die ‚Schließung’ des Textes nicht nur eine Generalisierung und Anonymisierung von poetischen Kommunikationssituationen voraussetzt (…) Sondern es könnte sich dann auch zeigen, daß an die stabile soziale Institution des Autors sowie an generalisierte und anonymisierte Kommunikationsverhältnisse gebundene und daher weitgehend invariante Text fortschreitend verzichten kann (…) auf jene Formierungen der literarischen Rede, welche unter den Voraussetzungen okkasioneller poetischer Kommunikation die Bedingung ihrer Möglichkeit waren. Der Text und seine Textualität sind dann etwas ganz anderes, weil seine Situationalität sich grundsätzlich verändert hat.
Die Geschichte der mediävistischen Literaturgeschichtsschreibung im 20. Jahrhundert ist die Geschichte einer zunehmenden Verunsicherung. Diese Verunsicherung ergibt sich weniger aus dem Problem, daß das Zusammentragen und Darstellen der beständig gewachsenen Menge an Fakten und Daten dem einzelnen kaum mehr möglich ist. [...] In dieser Situation scheint es [...] [Jans Haustein] vernünftig zu sein, wenn man das einer Literaturgeschichte zugrunde gelegte Material zunächst radikal begrenzt. [...] [Er möchte] für eine - erneute - Hinwendung der Literaturgeschichtsschreibung zur Region plädieren. Nur so, auf begrenztem Terrain und an einem überschaubarem Material, lassen sich Interpretationen und Überlieferungen sachgerecht aufeinander beziehen [...]. Für die thüringische Literaturgeschichte wären etwa die 'Losse-Sammlung' [...] mit Blick auf spätmittelalterliche Sammlungen von Minnereden oder die Pommersfeldener Handschrift im Kontext der Märenhandschriften einschlägig.
