Endoscopic Coblator™‐assisted management of encephaloceles
Authors: Smith Ncholas , Riley Kristen O. , Woodworth Bradford A. 
Published: August 2010

AbstractObjectives:Numerous studies have demonstrated the efficacy and safety of endoscopic management of cerebral spinal fluid (CSF) rhinorrhea, encephaloceles, and anterior skull base defects. Techniques have evolved as new instrumentation has developed, but typically involve meticulous bipolar cautery to decrease the potential for intracranial bleeding. The present study evaluated the Coblator™ as a novel tool in transnasal endoscopic management of encephaloceles.Study Design:Outcomes study.Methods:A prospective cohort involving 19 patients with 22 encephaloceles (19 spontaneous, 3 traumatic) reduced with the Coblator™ (radiofrequency coblation plus bipolar modality) was compared to a retrospective cohort of six encephaloceles (five spontaneous, one traumatic) removed with endoscopic bipolar cautery. Main outcome measures included duration of encephalocele removal and bleeding events. Bleeding encountered during removal was considered a minor event unless more than one attempt at cauterization was required. Other data collected included standard demographics, encephalocele size, and complications.Results:Average duration of coblation‐assisted encephalocele removal was 15.8 minutes compared to 46 minutes with standard bipolar cautery (P = .0003). Average number of bleeding episodes did not significantly differ between groups (Coblator™, 1.0 ± 1.57 vs. bipolar, 1.17 ± 0.98; P = .80). One episode of major bleeding occurred in the coblation group when an anterior ethmoid artery was encountered during removal. Encephalocele size was similar between groups (Coblator™, 17.4 mm vs. bipolar, 16.6 mm; P = .65).Conclusions:Radiofrequency coblation significantly increased intraoperative speed during encephalocele removal with similar hemostatic properties when compared to bipolar cautery alone and represents a useful instrument in the management of encephaloceles.

AbstractObjectives:To evaluate the reliability and validity of the assessment tool for endoscopic sinus surgery when used in the operating room for in‐training assessment of operative competency; to identify the tasks that may serve as the best indicators for overall surgical performance.Study Design:Cross‐sectional validation study.Methods:We implemented the global and checklist parts of the endoscopic sinus surgery (ESS) assessment tool to evaluate the surgical skills of 13 Otolaryngology–Head & Neck Surgery residents (PGY 1–5) in the operating room over a period of 15 months. Rhinology faculty scored residents' performance of every step of ESS at the end of each procedure using a previously validated tool. Construct validity was calculated by comparing scores across training levels (using analysis of variance [ANOVA]). Regression analysis was performed to identify tasks on the ESS checklist that most strongly correlated to the overall surgical performance.Results:Construct validity was demonstrated with senior residents performing better than junior residents. Average checklist and global scores improved with the number of days on rhinology rotation. “Identification of uncinate and boundaries” was found to be the strongest predictor of overall surgical performance.Conclusions:The results indicate that this evaluation tool is a reliable and valid instrument for the assessment of surgical competency in the operating room. It can be used to identify weak areas of performance for which additional training may be required early in the rotation/training. Laryngoscope, 2010
Pathological laughter in Gilles de la Tourette syndrome: An unusual phonic tic
Authors: Cavanna Andrea E. , Ali Fizzah , Leckman James F. , Robertson Mary M. 
Published: August 2010

AbstractPatients with Gilles de la Tourette syndrome (GTS) can display socially inappropriate behaviors as part of their multiform tic phenomenology. Pathological laughter (PL), defined as the presence of episodic and contextually inappropriate outbursts of laughter, has been detailed as a symptom of various psychiatric and neurological conditions. We present a case series of eight subjects diagnosed with GTS who reported PL as part of their tic repertoire. All subjects experienced PL as a simple phonic tic, accompanied by characteristic premonitory urges and significant impairment in social interactions. In addition, all patients presented with multiple tic‐related symptoms (mainly self‐injurious behaviors and echolalia, n = 7; palilalia, n = 6; coprolalia/mental coprolalia, n = 5), and six patients had comorbid conditions (in particular obsessive‐compulsive disorder/behaviors, n = 7; attention‐deficit hyperactivity disorder, n = 4). We suggest that the pathophysiological mechanisms underlying the expression of PL as a tic could involve a dissociation between frontostriatal and limbic networks. © 2010 Movement Disorder Society.
The Self‐Stigma of Depression Scale (SSDS): development and psychometric evaluation of a new instrument
Authors: Barney Lisa J. , Griffiths Kathleen M. , Christensen Helen , Jorm Anthony F. 
Published: August 2010

AbstractSelf‐stigma may feature strongly and be detrimental for people with depression, but the understanding of its nature and prevalence is limited by the lack of psychometrically‐validated measures. This study aimed to develop and validate a measure of self‐stigma about depression. Items assessing self‐stigma were developed from focus group discussions, and were tested and refined over three studies using surveys of 408 university students, 330 members of a depression Internet network, and 1312 members of the general Australian public. Evaluation involved item‐level and bivariate analyses, and factor analytic procedures. Items performed consistently across the three surveys. The resulting Self‐Stigma of Depression Scale (SSDS) comprised 16 items representing subscales of Shame, Self‐Blame, Social Inadequacy, and Help‐Seeking Inhibition. Construct validity, internal consistency and test–retest reliability were satisfactory. The SSDS distinguishes self‐stigma from perceptions of stigma by others, yields in‐depth information about self‐stigma of depression, and possesses good psychometric properties. It is a promising tool for the measurement of self‐stigma and is likely to be useful in further understanding self‐stigma and evaluating stigma interventions.Copyright © 2010 John Wiley & Sons, Ltd.

Published: August 2010

AbstractEchis carinatus venom (EV) is a complex mixture of toxins that contribute to its lethality. EV proteolytic activity was analyzed by zymography, chromogenic assays, and SDS‐PAGE. To understand the molecular mechanism of the envenomation, we investigated the in vitro effect of EV on human plasma proteins. We looked for EV protein substrates and their proteolytic fragments. We analyzed EV proteolytic activity on standard proteins such as prothrombin or fibrinogen. To set up the optimal EV:plasma protein ratio conditions, plasma was incubated with EV (treated plasma), depleted of abundant proteins, and subjected to SDS‐PAGE. Samples from control and treated plasma were also analyzed by 2‐DE/MALDI‐TOF MS, leading to the identification of four classes of plasma proteins cleaved by EV: proteases, protease inhibitors, binding proteins, and transporters. EV mainly proteolyzes entire proteins but can also act on physiological fragments. In summary, the physiological effects of EV proteases involve other important processes in addition to blood coagulation; complement activation and hemoglobin metabolism are also affected. In particular, the cleavage of protease inhibitors appears to be the mechanism through which the venom neutralizes the body's defenses.
Vibrations of tetrahedral Co and Cu clusters on a Cu(111) surface

Published: August 2010

AbstractVibrational properties of tetrahedral clusters of Cu and Co on the Cu(111) surface are studied by using interatomic interaction potentials constructed within tight‐binding second moment approximation. It was shown that interaction of the Co4 and Cu4 clusters with the substrate leads to arising of frustrated translation and frustrated rotation in‐plane polarized vibrational modes localized on the cluster atoms. The vibrational modes of the free Cu4 cluster upon its adsorption on the Cu(111) surface mix with Cu bulk phonons and become almost delocalized. Contrary to that, in the Co4 cluster on the surface the high frequency modes remain strongly localized and mixed with the nearest neighbor atoms vibrations. The highest frequency vibration of the Co4 cluster splits due to different interaction with certain groups of nearest neighbor atoms (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Thermodynamic properties of Au–Pd nanostructured surfaces studied by atomic scale modelling
Authors: Atanasov Ivailo , Hou Marc 
Published: August 2010

AbstractWe address the question of the sensitivity of the segregation and ordering properties to the surface energy of Au‐Pd alloys and nanoalloys. To this purpose, the parameterization of an EAM potential fitted to the vacancy formation energy was modified in order to predict surface energies closer to the experimentally measured ones. Metropolis Monte Carlo sampling was used to predict segregation and ordering. We show in the detail that modifying the surface energies of Au and Pd by up to 50 percent and, their surface energy difference by about 35 percent is of no major importance for the ordering and segregation properties of nanostructured Au‐Pd alloy surfaces (© 2010 WILEY‐VCH Verlag GmbH & Co.

Design and preliminary results of a DNA chip for the detection of microorganisms in water samples
Authors: Martins Nelson , Vale Filipa F. , Vieira Helena 
Published: August 2010

AbstractWaterborne pathogens are responsible for several diseases, either due to the consumption of contaminated drinking water or due to the contact with polluted recreational waters. There is an increasing awareness that emergent and viral pathogens should also be monitored for determining water quality. Conventional detection methodologies present several shortcomings, such as reliance in indicator species, low throughput and increasing resources as more species are to be detected. DNA chips have the potential to serve as surveillance systems for the simultaneous detection of pathogens, overcoming these limitations. In the present study, a rapid method for the detection of multiple waterborne pathogens (bacteria and viruses) was developed, using a DNA chip (AQUACHIP®). Species and group specific probes were implemented on a DNA chip, both for mandatory and non‐mandatory microorganisms. Considerations regarding the AQUACHIP® design (probe layout, replicates and dilutions), DNA labelling and amplification, and preliminary results of the application of the chip for the detection of E. coli DNA are presented (© 2010 WILEY‐VCH Verlag GmbH & Co.

Experimental design for determination of effective parameters in hydrothermal synthesis of TiO2‐derived nanotubes
Authors: Safaei M. , Sarraf‐Mamoory R. , Rashidzadeh M. , Manteghian M. 
Published: August 2010

AbstractIn this paper, a screening approach, involving the use of Plackett‐Burman experimental design, permitted the evaluation of the effects of 8 parameters from hydrothermal synthesis of TiO2 derived nanotubes such as raw materials surface area, m, filling factor, temperature, time, aging, stirring, and HCl concentration on the surface area of products. The study highlights the role of filling factor, stirring, temperature, raw materials, and time conditions on surface area of responses.TEM micrographs showed that the morphologies for high, medium, and low surface areas of products are nanotubes, nanowires, and nanospheres, respectively. The N2 adsorption‐desorption isotherms and pore size distributions showed that with decreasing surface area, the area of the hysteresis loops and gas volumes of N2 adsorbed are decreased. Also, the hysteresis loops shift to the region of higher relative pressure. Therefore, An increase in average pore size and a decrease in pore volume reduced surface area of product (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Initial growth stages of AlF3 on Cu(100): an STM study
Authors: Moreno‐López J. C. , Passeggi M. C. G. , Ruano G. , Vidal R. A. , Ferrón J. 
Published: August 2010

AbstractIn this study we present results concerning the early growth stages of an insulator‐metal interface by means of scanning tunnelling microscopy. In particular, we report the growth of aluminium fluoride (AlF3) islands over a Cu (100) surface at room temperature, from sub‐monola‐yer coverages up to 1.25 monolayers. These islands cover the substrate with a single monolayer film up to depositions of 0.80 monolayers, with 3D growth beyond this coverage. High voltages (V ≥ 2.50 V) are needed to obtain STM images, showing the insulator character of the AlF3 islands. Important modifications are observed in the AlF3/Cu (100) surface after an annealing treatment. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Conduction and electroluminescence from organic continuous and nanofiber thin films
Authors: Kjelstrup‐Hansen Jakob , Liu Xuhai , Henrichsen Henrik H. , Thilsing‐Hansen Kasper , Rubahn Horst‐Günter 
Published: August 2010

AbstractIn this work, the electrical and electroluminescence properties of para‐hexaphenylene (p6P) thin films and nanofibers have been investigated in a field‐effect transistor device configuration with interdigitated source‐drain bottom contact electrodes. P‐type behavior of thin films is observed with a mobility of 1×10‐6 cm2/Vs and a threshold voltage around ‐30 V. AC gated devices show electroluminescence for both thin films and stamped nanofibers even when the drain electrode is floating. This suggests either hole and electron injection from the same electrode or impact ionization. The highest electroluminescence intensity is observed from thin film FETs with a 2.5 µm source‐drain gap. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Nonrelativistic CI calculations for B+, B, and B− ground states
Authors: Almora‐Díaz César X. , Bunge Carlos F. 
Published: August 2010

AbstractState of the art configuration interaction (CI) techniques are used to obtain the best possible nonrelativistic CI results for B+, B, and B− ground states using energy‐optimized basis sets of 252, 294, and 294 radial Slater‐type functions, respectively. For positive boron, E(B+) = −24.348861 + ΔEbie = −24.348883(1) a.u.(B) with a basis set incompleteness error ΔEbie = −0.000022(1), in good agreement with the latest exponentially correlated Gaussian (ECG) result of −24.348883 a.u.(B) of Komasa et al. (Phys Rev A, 2002, 65, 042507). For neutral B, E(B) = −24.653837 −0.000024(2) = −24.653861(2), which is the most accurate ab initio estimate and lies slightly below a recent (not fully optimized) ECG result of −24.653840 a.u.(B) of Bubin et al (J Chem Phys, 2009, 131, 044128). For negative boron, E(B−) = −24.664014 −0.000024(2) to which an energy error of −0.000001 must be added to give −24.664039(2), which is the first fully correlated ab initio result. Comparison with experimental values of ionization energy and electron affinity must await the results of corresponding relativistic calculations, in progress. © 2010 Wiley Periodicals, Inc.

Seed‐to‐seed potential allelopathic effects between Ligularia virgaurea and native grass species of Tibetan alpine grasslands
Authors: Zhang Shiting , Liu Junpeng , Bao Xiaohui , Niu Kechang 
Published: August 2010

AbstractAllelopathy is an important process in plant communities, but the role of seed allelopathy in natural ecosystems remains poorly understood. In the present study, we examined the potential allelopathic effects of Ligularia virgaurea (a dominant species in degraded Tibetan grasslands) seeds on the germination of four native grass species (Festuca sinensis, Agrostis gigantean, Bromus inermis, and Elymus nutans). The results showed that L. virgaurea seeds can have potential allelopathic effects on seed germination, mean time to germination and root growth rates of native grass species. We further demonstrate that these effects are driven by a water‐soluble seed leachate. Species with smaller seeds were generally more sensitive than larger seeded species. The results suggest that seed‐to‐seed allelopathic potential may be an important mechanism driving the dominance of L. virgaurea in degraded alpine grasslands on the Tibetan Plateau. Further studies are required to demonstrate effects of seed‐to‐seed potential allelopathy in a field setting.
National identification of Dutch youth: An exploratory study☆
Authors: Oppenheimer Louis 
Published: August 2010

ABSTRACT246 Dutch participants aged 8, 10, 12, 14, and 16 years were presented with the Strength of Identification Scale (SoIS; Barrett, 2007) and the National Identity scale based on Cultural and Historical achievements (NICH; derived from the NATID, Keillor & Hult, 1999). The study aimed to examine the extent and nature of Dutch children and adolescents’ identification with The Netherlands and to explore whether changes in aspects of national identification are evident across age. Already at age 8 years children identify themselves with the Dutch nation and with increasing age national identification becomes primarily determined by the extent that participants consider themselves to be Dutch and show positive affect towards the Dutch nation. Identification on the basis of cultural and historical achievements of the Dutch people became less evident following the age of 10 years although Dutch historical and cultural achievements contributed significantly to the extent of national identification.
Non-K-exact uniform Roe C*-algebras

AbstractWe prove that uniform Roe C*-algebras C*uX associated to some expander graphs X coming from discrete groups with property (τ) are not K-exact. In particular, we show that this is the case for the expander obtained as Cayley graphs of a sequence of alternating groups (with appropriately chosen generating sets).
THE INFLUENCE OF GERMAN STATE-THEORY ON THE DESIGN OF THE AUSTRALIAN CONSTITUTION
Authors: Aroney Nicholas 
Published: August 2010

AbstractThis article draws attention to an important but neglected story about the dissemination of German and Swiss state-theories among English-speaking scholars in the second half of the 19th century and the influence of these ideas on those who designed and drafted the Australian Constitution. In particular, the article focuses upon the theories of federalism developed by the Swiss-born scholar, Johann Caspar Bluntschli, and the Saxon-born Georg Jellinek, and explains their influence, via the British historian, Edward A Freeman, and the American political scientist, John W Burgess, upon the framers of the Australian Constitution. The story is important because it illustrates the way in which constitutional ideas can be transmitted from one social and political context into a very different one, undergoing significant, though often subtle, modifications and adaptations in the process. The story is also important because it sheds light on the way in which the framers of the Australian Constitution came to conceive of the kind of federal system that they wished to see created. The story seems to have been overlooked, however, not only due to a general neglect of the intellectual history of the Australian Constitution, but also due to the assumption that prevailing Australian political and legal ideas were of Anglo-American provenance. While this assumption generally holds true, a closer examination of the intellectual context of Australian federalism reveals a surprisingly significant German influence on the framers of the Australian Constitution.
THE EFTA COURT 15 YEARS ON
Authors: Fredriksen Halvard Haukeland 
Published: August 2010

AbstractFor over 15 years, the reports of the EEA Agreement's imminent demise have proven to be greatly exaggerated. In this article it is argued that a great deal of the credit for this accomplishment is due to the EFTA Court. Through a distinctly dynamic approach to the Agreement, the EFTA Court has been able to convince an initially sceptical ECJ that the goal of extending the internal market to include the EFTA States is actually achievable. For the EFTA States, the consequence is a more ‘supranational’ EEA Agreement than originally conceived. Further, it is shown that the EFTA Court appears, in hard cases, to lean even further towards teleological (ie integrationist) interpretation than the ECJ. It is suggested that this may be due to to structural imbalances between the two EEA courts, the EFTA Court's desire to prove its independence from the EFTA States and its quest for recognition from the ECJ.
Pliny,Letters5.10 and the Literary Career of Suetonius
Authors: Power Tristan J. 
Published: August 2010

ABSTRACTThis paper establishes a new date for the publication of Suetonius’Illustrious Menthrough allusions to Suetonius’Virgilin Pliny,Letters5.10. These allusions are part of a much wider network of allusions, both within this particular letter and more generally in Pliny's Book 5, that revolves around the theme of unpublished writings. It is a partial or full publication of theIllustrious Menthat probably led to Suetonius’ award of theius trium liberorumina.d.110, and he may now have published all of theCaesarsbefore his dismissal by Hadrian ina.d.122.
