FACTS, FICTION, AND FRICTION IN A DIFFICULT RELATIONSHIP:VIENNA AND PROVINCIAL AUSTRIA
Authors: Bushell Anthony 
Published: March 2012

ABSTRACT The dominance of Vienna in almost all spheres of political and cultural life of the Second Republic has meant that the Austrian provinces have received correspondingly less attention in literary and scholarly works. Where such depictions of the provinces in post‐1945 literature do exist they have been far from flattering, suggesting in particular a deliberate refusal by those who live beyond Vienna to engage with Austria's painful recent history. The tensions between Vienna and the provinces are discussed in this article, which seeks to show how historical, structural, administrative, and demographic factors have long been at play in creating the antagonism between the former Residenzstadt and non‐metropolitan Austria. Current political concerns, especially relating to immigration issues, duplicate the experience of rapid migration trends in Vienna in the nineteenth century and raise the question of how in the twenty‐first century the relationship between the Austrian provinces and Vienna, especially in literary and political responses, will draw on those earlier experiences.Die Vorrangstellung Wiens in fast allen Bereichen des politischen und kulturellen Lebens der Zweiten Republik hat zwangsläufig zu einer allgemeinen Vernachlässigung der auf die anderen österreichischen Bundesländer gerichteten Aufmerksamkeit geführt. Im Spiegel der Nachkriegsliteratur scheint das ländliche Österreich oft hoffnungslos in seine Vorurteile verstrickt und durch einen auffallenden Widerwillen gekennzeichnet, sich mit der jüngsten Geschichte Österreichs auseinanderzusetzen. Das Spannungsverhältnis zwischen Wien und den Regionen lässt sich aber zum größten Teil historisch, demographisch, institutionell und strukturell erklären. Es erhebt sich die Frage, ob die anderen Bundesländer in ihrem heutigen Verhältnis zum Bundesland Wien aus früheren Erlebnissen politisch und literarisch lernen werden, vor allem aus der Erfahrung der Massenmigration im neunzehnten Jahrhundert.
Of love and national borders: the Croatian anthem ‘Our Beautiful Homeland’
Authors: Kelen Christopher , Pavković Aleksandar 
Published: March 2012

AbstractCroatia became a UN member only in 1992, after the violent break‐up of Yugoslavia. Its anthem is marked by historically founded ambivalences as to the nature and territorial extent of the nation in question. This article offers an interpretation of the current version of the anthem and an analysis of the narrative and imagery of the nineteenth‐century poem from which the anthem originates. Three of the anthem's four stanzas speak about the Croats’ love for their homeland and their people and of the steadfastness and immortality of their love; the remaining stanza extolls the beauty of the homeland. By addressing the homeland's rivers and the sea directly, its singers appropriate this geography and so demarcate the borders of their much‐loved homeland. The anthem thus asserts Croatia's unity (against potential pretenders) and its unbreakable ties with its people. In contrast, the original fourteen‐stanza poem ‘The Croatian Homeland’, written in 1835, is a paean to the Croats’ ties to nature, their simple life and bravery – the romantic virtues of pure national souls. On their path to anthemhood, the four stanzas drawn from this poem have undergone significant modifications and additions, the result being a song that is doubly reassuring: it reassures the singers first of the people's love for themselves as a people, and second that this love is the means by which the ‘natural’ territory of the homeland is maintained.

J. Neurochem. (2012) 121, 830–839.AbstractMitochondrial dysfunction represents a critical event during the pathogenesis of Parkinson’s disease (PD) and expanding evidences demonstrate that an altered balance in mitochondrial fission/fusion is likely an important mechanism leading to mitochondrial and neuronal dysfunction/degeneration. In this study, we investigated whether DJ‐1 is involved in the regulation of mitochondrial dynamics and function in neuronal cells. Confocal and electron microscopic analysis demonstrated that M17 human neuroblastoma cells over‐expressing wild‐type DJ‐1 (WT DJ‐1 cells) displayed elongated mitochondria while M17 cells over‐expressing PD‐associated DJ‐1 mutants (R98Q, D149A and L166P) (mutant DJ‐1 cells) showed significant increase of fragmented mitochondria. Similar mitochondrial fragmentation was also noted in primary hippocampal neurons over‐expressing PD‐associated mutant forms of DJ‐1. Functional analysis revealed that over‐expression of PD‐associated DJ‐1 mutants resulted in mitochondria dysfunction and increased neuronal vulnerability to oxidative stress (H2O2) or neurotoxin. Further immunoblot studies demonstrated that levels of dynamin‐like protein (DLP1), also known as Drp1, a regulator of mitochondrial fission, was significantly decreased in WT DJ‐1 cells but increased in mutant DJ‐1 cells. Importantly, DLP1 knockdown in these mutant DJ‐1 cells rescued the abnormal mitochondria morphology and all associated mitochondria/neuronal dysfunction. Taken together, these studies suggest that DJ‐1 is involved in the regulation of mitochondrial dynamics through modulation of DLP1 expression and PD‐associated DJ‐1 mutations may cause PD by impairing mitochondrial dynamics and function.

AbstractAtorvastatin has shown to possess neuroprotective, antiexcitotoxic, and antiepileptic effects besides its cholesterol‐lowering properties. Nitric oxide (NO) may be responsible for a group of these effects. In the present study, a model of clonic seizure induced by pentylenetetrazole (PTZ) in male NMRI mice was used to investigate the anticonvulsive effects of atorvastatin through NO‐dependent pathways. Atorvastatin (5 mg/kg) significantly increased the seizure threshold (P < 0.001). Moreover, L‐arginine (a precursor of NO) significantly (P < 0.01) potentiated the anticonvulsive effects of subeffective doses of atorvastatin (1 mg/kg). Finally, L‐NAME [L‐arginine methyl ester dihydrochloride], a nonspecific NO synthase inhibitor, completely abolished the anticonvulsive properties of atorvastatin. Our findings demonstrated the role of atorvastatin as an anticonvulsive agent and showed the effects to be mediated through NO‐related pathways.
Can shoulder dystocia be reliably predicted?
Authors: Dodd Jodie M. , Catcheside Britt , Scheil Wendy 
Published: March 2012

AimsTo evaluate factors reported to increase the risk of shoulder dystocia, and to evaluate their predictive value at a population level.MethodsThe South Australian Pregnancy Outcome Unit's population database from 2005 to 2010 was accessed to determine the occurrence of shoulder dystocia in addition to reported risk factors, including age, parity, self‐reported ethnicity, presence of diabetes and infant birth weight. Odds ratios (and 95% confidence interval) of shoulder dystocia was calculated for each risk factor, which were then incorporated into a logistic regression model. Test characteristics for each variable in predicting shoulder dystocia were calculated.ResultsAs a proportion of all births, the reported rate of shoulder dystocia increased significantly from 0.95% in 2005 to 1.38% in 2010 (P = 0.0002). Using a logistic regression model, induction of labour and infant birth weight greater than both 4000 and 4500 g were identified as significant independent predictors of shoulder dystocia. The value of risk factors alone and when incorporated into the logistic regression model was poorly predictive of the occurrence of shoulder dystocia.ConclusionsWhile there are a number of factors associated with an increased risk of shoulder dystocia, none are of sufficient sensitivity or positive predictive value to allow their use clinically to reliably and accurately identify the occurrence of shoulder dystocia.

AbstractObjectivesTo examine nurse home visitors' perspectives of and intentions to report children's exposure to intimate partner violence (IPV) in the context of the home visitation setting.Design and SampleCross‐sectional study of 532 nurse home visitors in the Nurse‐Family Partnership home visitation program.MeasuresA web‐based questionnaire assessing nurse home visitors' support for and attitudes toward mandatory reporting of children's exposure to IPV. Nurses' considerations of what levels of exposure constitute maltreatment and their intended reporting behaviors were also examined.ResultsVariability and uncertainty were observed in participants' attitudes as well as in their determinations as to which situations constitute child maltreatment. Most of the sample believed reporting exposure to IPV can help the battered woman (67%) and can protect children (92%), while 56% indicated that reporting can negatively affect the nurse‐client relationship. Nurses were more likely to endorse reporting children's exposure to IPV when the child was at greatest risk for being physically injured as a result of IPV.ConclusionsTraining about maltreatment reporting procedures in home visitation programs should focus on the interpretation of child maltreatment laws as well as collaborations with local child protection service agencies to determine if children's exposure to IPV is reportable.
MOLECULAR PHYLOGENY OF THE GENUS KUMANOA (BATRACHOSPERMALES, RHODOPHYTA)1
Authors: Vis Morgan L. , Necchi Orlando , Chiasson Wayne B. , Entwisle Timothy J. 
Published: March 2012

Species belonging to the newly established genus Kumanoa were sampled from locations worldwide. DNA sequence data from the rbcL gene, cox1 barcode region, and universal plastid amplicon (UPA) were collected. The new sequence data for the rbcL were combined with the extensive batrachospermalean rbcL data available in GenBank. Single gene rbcL results showed the genus Kumanoa to be a well‐supported clade, and there was high statistical support for many of the terminal nodes. However, with this gene alone, there was very little support for any of the internal nodes. Analysis of the concatenated data set (rbcL, cox1, and UPA) provided higher statistical support across the tree. The taxa K. vittata and K. amazonensis formed a basal grade, and both were on relatively long branches. Three new species are proposed, K. holtonii, K. gudjewga, and K. novaecaledonensis; K. procarpa var. americana is raised to species level. In addition, the synonymy of K. capensis and K. breviarticulata is proposed, with K. capensis having precedence. Five new combinations are made, bringing the total number of accepted species in Kumanoa to 31. The phylogenetic analyses did not reveal any interpretable biogeographic patterns within the genus (e.g., K. spermatiophora from the tropical oceanic island Maui, Hawaii, was sister to K. faroensis from temperate midcontinental Ohio in North America). Previously hypothesized relationships among groups of species were not substantiated in the phylogenetic analyses, and no intrageneric classification is recommended based on current knowledge.

Psychopathology and Symptoms of Atrial Fibrillation. Introduction: Current guidelines recommend that the choice of AF management strategy be guided by the symptomatic status of the patient when in AF. However, little is known regarding what drives AF symptoms. Several limited studies suggest that psychological distress may be linked with AF symptom severity.
Methods:
A total of 300 patients with documented AF completed a questionnaire assessing general health and well‐being, including a comprehensive psychological assessment as well as disease‐specific measures of AF symptom severity. AF burden was determined by 1‐week continuous looping monitor in a subset of patients. Analysis of covariance was used to determine the association between individual measures of depression, anxiety, and somatization disorder symptom severity with measures of general health status and AF‐specific symptom severity, adjusting for important confounders.
Results:
Patients with worsened severity of depression, anxiety, or somatization disorder symptoms had an associated increase in the severity of symptoms attributed to AF regardless of AF severity scale used (P < 0.0001 for each measure of psychological distress). This association persisted after adjusting for important confounders. Increasing severity of depression and anxiety symptoms were also associated with increased visits to medical care for AF management.
Conclusions:
Our study demonstrates the consequence of psychological distress on AF‐specific symptom severity and healthcare resource utilization. Psychological well‐being may strongly influence symptom severity and healthcare utilization. An assessment of psychological distress may be an important adjunct to standard AF management that warrants further study, particularly if symptom relief is the primary goal.(J Cardiovasc Electrophysiol, Vol. 23, pp. 473‐478, May 2012)

QTc for Assessing Significance of LQT Variants. Introduction: Genetic variants represent benign single‐nucleotide polymorphisms, disease causing mutations or variants of unknown significance (VUS). Resting, exercise, and recovery QTc intervals have been utilized to detect long‐QT syndrome (LQTS) mutations. We sought to provide clinical data that may assist in classifying the presented VUS as disease causing/benign and to determine whether resting and/or end‐recovery QT parameters can evaluate the significance of VUS.Methods and Results: Twenty‐six patients with a VUS in genes associated with LQTS (15 females, age 38 ± 16 years) and 26 age and gender matched controls (age 37 ± 20 years) were included. There were 10 VUS (5 KCNQ1, 4 KCNH2, 1 KCNE1) in 12 families. All but 1 VUS was associated with sudden cardiac death (SCD), aborted SCD or Torsade de pointes. A Schwartz score of ≥3.5 was observed in at least 1 family member with each VUS. Resting QTc was marginally longer in VUS patients compared with controls (458 ± 48 vs 437 ± 25, P = 0.052). A prolonged resting QTc (>470 ms males, >480 ms females) identified 6 VUS carriers and 1 control. VUS carriers had a substantially longer end‐recovery QTc (502 ± 68 vs 427 ± 17, P < 0.01) with an end‐recovery QTc > 445 ms in 20/26 VUS patients compared to 2/26 controls (P < 0.01). The area under the receiver operating characteristic curve for resting QTc was 0.68 (95% CI, 0.53–0.83, P = 0.03) compared to the end‐recovery QTc of 0.88 (95% CI, 0.76–0.99, P < 0.0001).Conclusion: Variants in the current study appear to be disease causing. The end‐recovery QTc is a useful metric when interpreting LQT VUS. (J Cardiovasc Electrophysiol, Vol. 23, pp. 637–642, June 2012)

Gold versus Platinum Irrigated Tip Ablation Catheters. Introduction: In order to optimize power delivery into the myocardium during radiofrequency ablation (RFA) without overheating the electrode tip, active cooling of the tip electrode as well as electrode tips made of gold have evolved. Recently, an externally irrigated gold tip electrode ablation catheter has been developed to combine the advantages of these 2 technologies. We sought to investigate the procedural parameters tip temperature, delivered power and cooling flow requirements of the irrigated gold tip catheter in comparison to the conventional irrigated platinum iridium (Pt) tip catheter in pulmonary vein isolation (PVI) and cavotricuspid isthmus (CTI) ablation.
Methods and Results:
Sixty patients referred for first PVI were randomized into ablation with irrigated gold tip catheter versus irrigated Pt tip catheter. Forty‐nine patients received ablation of CTI following PVI. Mean and standard deviation from all measurements were calculated for each patient. During RFA of pulmonary veins, mean catheter tip temperature was significantly lower in the gold group (35.4 ± 0.9 °C vs 38.2 ± 0.8 °C, P < 0.001), and total amount of delivered energy was higher (1303.1 ± 81.1 W vs 1223.7 ± 115.6 W, P = 0.004). During CTI ablation, necessary saline flow was almost 2.5‐fold lower in the gold group (22.5 ± 5.9 mL/min vs 52.5 ± 9.7 mL/min, P < 0.001), accompanied by significantly lower tip temperature (39.1 ± 0.6 °C vs 40.5 ± 1.4 °C, P < 0.001).
Conclusion:
The irrigated gold tip electrode allows to deliver significantly more energy at a lower electrode tip temperature in RFA of PV and CTI in comparison to the irrigated Pt tip electrode. The required saline flow during CTI ablation is much lower than in Pt. (J Cardiovasc Electrophysiol, Vol. 23, pp. 717‐721, July 2012)
WE HAVE ALWAYS BEEN MODERN: Museums, Collections, and Modernity in the Caribbean
Authors: Modest Wayne 
Published: March 2012

AbstractIn this article, I explore the ways in which notions of the ancient and the modern have helped to shape early museological interest and practices in the Caribbean. I argue that the Caribbean, and for my purposes Jamaica, occupies an ambiguous place between the ancient and the modern worlds—not ancient enough yet not modern enough—which has resulted in the material culture of the modern Caribbean being largely absent from anthropological (and in fact history) collections both in the Caribbean as well as in museums across Europe. The result is that the region has come to be defined materially primarily through its natural and not its cultural history, and thus is represented as a place of nature and not culture.
ENGAGING WITH PASTS IN THE PRESENT: Curators, Communities, and Exhibition Practice
Authors: Scott Mary Katherine 
Published: March 2012

AbstractArising from a one‐day symposium entitled “Ancient and Modern: Exhibiting the Past in the Present” at the University of East Anglia, United Kingdom, the theme for this special issue of Museum Anthropology focuses on contemporary museum practice. The contributors are specifically interested in the challenges of exhibiting “pasts” in the “present” while doing justice to the historical and modern peoples and cultures represented in exhibitions. The authors also explore related ideas about collaboration with source communities and how collecting practices have determined what is considered valuable and thus worthy of display in public museums.
REFLECTIONS ON COLLABORATION: Exhibiting Contemporary Maya Art
Authors: Scott Mary Katherine 
Published: March 2012

AbstractThis article describes the collaboration with Maya artisans during the exhibition, Crafting Maya Identity: Contemporary Wood Sculptures from the Puuc Region of Yucatán, Mexico. The exhibition called into question the applicability of Western systems of value and classification to the aesthetic works of other cultures and also explored notions of contemporary Maya identity in the context of the local tourism industry. The artisans’ presence during the exhibition and their engagement with the public during organized events created opportunities for visitors to learn more about the artisans and their work. This paper takes a critical look at the exhibition's successes and shortcomings by way of feedback from the artisans and the public and offers recommendations for future collaborative projects.

The Eu3+‐doped novel precursor glass in the K2O–SiO2–SrO–Bi2O3–Ta2O5 system was prepared using the melt‐quench technique. The transparent SrBi2Ta2O9 (SBT) glass‐ceramic nanocomposites were derived from this glass using a controlled crystallization process. The formation of SBT crystal phase, size, and morphology with increase in heat‐treatment time was examined using X‐ray diffraction, field emission scanning electron microscopy, and fourier transform infrared transmission spectroscopy. Vicker's hardness study indicates marked improvement of hardness in the glass‐ceramics compared to precursor glass. The photoluminescence spectra of Eu3+ ions exhibit emission transitions of 5D0→7Fj (j = 0, 1, 2, 3, and 4) and its excitation spectra show an intense absorption band at 467 nm. These spectra reveal that the Eu3+ ions are gradually entering into the SBT nanocrystals present in the glass‐ceramics. This study indicates that the incorporation of Eu3+ ions into SBT crystal lattice enhances the photoluminescence performance of the glass‐ceramics by two‐fold. It is believed that this work would generate significant impact in the exploration of SBT glass‐ceramic nanocomposites.
The gonadotropin‐releasing hormone antagonist protocol – the protocol of choice for the polycystic ovary syndrome patient undergoing controlled ovarian stimulation

Published: March 2012

Abstract Polycystic ovary syndrome (PCOS) patients are prone to develop ovarian hyperstimulation syndrome (OHSS), a condition which can be minimized or completely eliminated by the use of a gonadotropin‐releasing hormone agonist (GnRHa) trigger. In this commentary paper, we maintain that the gonadotropin‐releasing hormone antagonist protocol should be the protocol of choice for the PCOS patient undergoing ovarian stimulation with gonadotropins for in vitro fertilization. If an excessive ovarian response is encountered, the clinician will always have two options: either to trigger final oocyte maturation with a bolus of GnRHa and supplement the luteal phase with a small bolus of human chorionic gonadotropin in addition to the standard luteal phase support and transfer in the fresh cycle or, alternatively, to trigger with GnRHa and perform a total freeze, resulting in a complete elimination of OHSS and high ongoing pregnancy rates in the subsequent frozen–thawed transfer cycles.
