Published: June 2015

Objective To evaluate the safety, efficacy and durability of endovascular repair for proximal para-anastomotic aneurysms after previous open abdominal aortic aneurysms prosthetic reconstruction and share our experience. Methods We retrospectively reviewed the data of all patients with previous open abdominal aortic aneurysms prosthetic reconstruction who underwent endovascular repair for proximal para-anastomotic aneurysms between May 2003 and January 2013 in our center (Nuremberg South Hospital). Key clinical outcomes included technical success rate, peri-operative morbidity and mortality, mid-term complications, reinterventions and open conversion rates. Results Totally, 24 patients of proximal para-anastomotic aneurysm were treated by endovascular repair. Successful deployments of stent graft were achieved in all patients (100%). Median hospital stay was 6.7 days. One patient had minor type Ia endoleak and one patient developed wound infection. There were no early open conversions and deaths. During a median follow-up of 43 months (range, 7–67 months), computed tomography angiography revealed type Ia endoleaks in four patients (16.7%). The overall reintervention and open conversion rates during follow-up were 16.7% (4/24) and 4.2% (1/24), respectively. Estimates of freedom from reintervention were 91.7% at 1 year, 87.1% at 3 years and 80.9% at 5 years. There was significant difference in freedom from reintervention between proximal para-anastomotic aneurysms patients treated with tube and unibody bifurcated stent grafts (p = 0.034). The cumulative mortality rate was 12.5% (3/24), actuarial analysis for all patients estimated survival rates of 95.8% at 1 year and 87.3% at 5 years. Conclusions Proximal para-anastomotic aneurysms are severe complications after abdominal aortic aneurysm open reconstruction. Closer follow-up and prompt treatment are necessary. Endovascular treatment for proximal para-anastomotic aneurysms is effective, safe and durable. Unibody bifurcated stent graft proved to be suitable for most proximal para-anastomotic aneurysms with various anatomical features.
Family carers’ experience of the need for admission of their relative with an intellectual disability to an Assessment and Treatment Unit
Authors: James Neil 
Published: June 2015

Background: There is limited research that explores the experiences of family carers of individuals with an intellectual disability requiring admission to a specialist National Health Service Assessment and Treatment Unit. Accordingly, this study aimed to explore family carers’ experience in respect of this phenomenon and their relationships with professionals at this time. Methods: Interpretative phenomenological analysis was used. Six family carers (three mothers and three fathers) participated and were interviewed via the use of semi-structured interviews. Findings: Five major themes were developed to represent how carers made sense and gave meaning to their experience. They illustrate how this experience had a significant influence on their sense of value and self-identity. It resulted in higher levels of anxiety, stress and uncertainty about the future of their relative and their identity as a carer. Significantly, professionals are identified as having a pivotal role in influencing how carers come to view their sense of self, identity, value and importance. Conclusion: The admission of their relative was a time of increased vulnerability for carers in respect of maintaining a sense of self-identity. Engaging with services and professionals had a major influence on situating them within the social structure that makes up the formal system of support. This had a pivotal role in influencing and determining how participants identified with their sense of self.
Unique Case of Posterior Tibial Tendon Dysfunction After Stingray Strike
Authors: Hambright Dustin , Guss Daniel , Smith Jeremy T. 
Published: June 2015

Background. Posterior tibial tendon dysfunction is a common cause of adult acquired flatfoot deformity. The cause of posterior tibial tendon dysfunction is often multifactorial and may include repetitive microtrauma, poor blood supply to the tendon, and, rarely, traumatic rupture. Case Description. We present the case of a 69-year-old male with posterior tibial tendon dysfunction secondary to a stingray injury that occurred directly into the posterior tibial tendon. This injury led to an acquired adult flatfoot deformity that ultimately required surgical reconstruction. At the time of surgery, the posterior tibial tendon was severely degenerative at the site of skin penetration. Literature Review. Previous case reports of stingray injury describe full-thickness skin penetration with a subsequent inflammatory response and large zone of necrobiosis. This is the first reported case of stingray trauma and envenomation directly into tendon with subsequent tendon dysfunction. Clinical Relevance. There are thousands of stingray injuries in the United States annually. Injuries vary in severity depending on the type of stingray, size of stingray, and depth and location of injury. For certain injuries, such as direct penetration into tendon, early irrigation and debridement may limit subsequent deficits caused by progressive tendon dysfunction. Levels of Evidence: Therapeutic, Level IV: Case study
Impact of Femoroacetabular Impingement Morphology on Gait Assessment in Symptomatic Patients
Authors: Farkas Gary J. , Cvetanovich Gregory L. , Rajan Kumar B. , Espinoza Orías Alejandro A. , Nho Shane J. 
Published: June 2015

Background: Gait is abnormal in patients with femoroacetabular impingement (FAI). To date, studies have not correlated radiographic FAI morphology with gait abnormalities. Hypothesis: Gait abnormalities in FAI patients will be associated with radiographic FAI morphology. Study Design: Cross-sectional study. Level of Evidence: Level 4. Methods: Patients with symptomatic FAI (n = 20) underwent radiographic and gait analysis. Exclusion criteria included previous injuries or surgeries to the lower extremities or lumbar spine as well as bilateral symptomatic FAI. The alpha angle (AA) and center-edge angle (CEA) were measured on anteroposterior (AP) pelvis, Dunn lateral, and false-profile radiographs, and inter- and intraobserver variability was determined. Motion analysis techniques were used to obtain gait data including 3-dimensional kinematic and kinetic data. Descriptive analysis was performed using Spearman correlations for morphologic measurements. A stepwise regression model was used to examine the association of gait measures with AA and CEA. Results: Intraobserver agreement for the AA and CEA was 0.92 (CI, 0.80-0.97) and 0.90 (CI, 0.76-0.96), while interobserver agreement for the angles was 0.96 (CI, 0.89-0.98) and 0.96 (CI, 0.90-0.98), respectively. Descriptive analysis suggested correlations between AA and peak external hip and knee external rotation moments, maximum ankle flexion angle, and ankle range of motion (range, –0.51 to 0.42; P < 0.0001). The CEA correlated with stride, peak external ankle eversion and inversion moments, peak external knee extension moment, and peak external hip flexion moment (range, –0.44 to 0.51; P < 0.0001). We found that gait variables accounted for a large amount of variation in AA (8 variables accounted for 87% variation) and in CEA (7 variables accounted for 82% variation). Conclusion: Lower extremity gait parameters correlate highly with radiographic FAI morphology in symptomatic FAI patients. Clinical Relevance: Gait abnormalities are present in FAI patients and may be a useful measure in outcome studies.

Published: June 2015

Abstract

Background
Aim of this retrospective observational study was to compare upper and lower dental changes in patients treated with Rapid Maxillary Expansion (RME) and Mixed Maxillary Expansion (MME), assessed by dental cast analysis.

Methods
Treatment groups consisted of 42 patients: the RME group (n = 21) consisted of 13 female and 8 male subjects with the mean age of 8.8 years ± 1.37 at T0 and 9.6 years ± 1.45 at T1; the MME group (n = 21) consisted of 12 female and 9 male patients with a mean age of 8.9 years ± 2.34 at T0 and 10.5 years ± 2.08 at T1. The upper and lower arch analysis was performed on four dental bilateral landmarks, on upper and lower casts; also upper and lower arch depths were measured. The groups were compared using independent sample t-test to estimate dental changes in upper and lower arches.

Results
Before expansion treatment (T0), the groups were similar for all examined variables (p>0.05). In both RME and MME group, significant increments in all the variables for maxillary and mandibular arch widths were observed after treatment. No significant differences in maxillary and mandibular arch depths were observed at the end of treatment in both groups. An evaluation of the changes after RME and MME (T1) showed statistically significant differences in mandibular arch depth (p<0.001) and maxillary intercanine widths (p<0.05). Differences in maxillary arch depth and arch width measurements were not significant.

Conclusions
RME and MME can be considered two effective treatment options to improve transverse arch dimensions and gain space in the dental arches. A greater lower arch expansion was observed in the MME group, which might be attributed to the “lip bumper effects” observed in the MME protocol.

AbstractIn the field of textile and clothing, radio frequency identification (RFID), which is one of the most promising technological innovations, is used in manufacturing, inventory control, warehousing, distribution, logistics, automatic object tracking and supply chain management. Various retailers and manufacturers (of clothing as well as consumer goods) such as CVS, Tesco, Prada, Benetten, Wal-mart and Procter & Gamble, are now implementing the technology and exploring the impact of the technology on their business. RFID technologies may improve the potential benefits of supply chain management through reduction of inventory losses, increase of the efficiency and speed of processes and improvement of information accuracy. The basic of success lies in understanding the technology and other features to minimize the potential problems. Although the technology existed for several years, the technological challenges and cost issues are the major hurdles for the widespread use of RFID. In this paper, the authors have addressed the technology of RFID and various applications related to inventory management, production control, retail management, brand segregation etc. in textile and clothing industry. In addition, the disadvantages, challenges and future directions of RFID technology have also been highlighted.
A temporal trend in compliance measurements near a gas hydrate accumulation, Northern Cascadia
Authors: Roach Lisa A. N. , Edwards R. Nigel 
Published: June 2015

Ocean surface gravity waves produce temporally correlated pressure and vertical displacements on the ocean floor. Compliance is the ratio between the pressure and the resulting displacement. Pressures are measured by a differential pressure gauge, whereas a broadband seismometer measures velocities that are directly related to the displacements in the frequency domain. These instruments are installed on the Cascadia accretionary prism as part of NEPTUNE Canada’s ocean-floor network. Gas hydrates have the property of stiffening marine sediment, i.e., reducing the compliance. A compliance measurement is dependent on the elastic parameters of the sediment, particularly, the shear modulus. We have computed compliance from raw data, daily, for 203 days and determined the temporal variation in shear modulus of a region approximately 390 m northeast of the undersea area known as Bullseye Vent. Our aim was to investigate the evolution of the elastic properties of the subsurface in this region. The compliance was determined over a bandwidth of 0.01–0.03 Hz, and had peak sensitivity to the sediment elastic structure at approximately 275 m below seafloor, for a water depth of 1250 m — determined by the gravity wave dispersion relation. Bullseye Vent is not a steady-state system! We observed a linear decrease in compliance of approximately 1% between October 2010 and May 2011, corresponding with an average change of 1% in the shear modulus over the depth of investigation. This corresponds to up to a 13% change solely in gas hydrate content in the first 100 m; a change that resulted from a simplified 1D four-layer model, which does not reflect the complexity and three-dimensionality of the hydrate system. A 13% change in hydrate content was likely an overestimate because the compliance function at 1250 m had limited sensitivity to the uppermost sediments.
Total Synthesis and Structure Revision of Mirubactin, and Its Iron Binding Activity

Published: June 2015

Abstract
Dechloro-chlorocatechelin A (3), a deschloro-derivative of a microbial siderophore chlorocatechelin A (2), was synthesized from 2,3-dihydroxybenzoic acid, d-arginine, and 1-benzyl d-glutamate. The spectral data were unambiguously identical with those of mirubactin (1), revising its chemical structure. Mirubactin showed potent iron binding affinity, which was comparable to that of chlorocatechelin A (2).

Published: June 2015

Abstract
The interaction between biomolecules and inorganic materials has gained much interest for the development of sensors and highly controlled materials in scale and composition. For this purpose, 4F2, a VHH antibody with high affinity and specificity toward zinc oxide (ZnO) surfaces has been constructed. Here, we report that 4F2 also has an affinity toward zinc ion (Zn2+). The stability of 4F2 and its Zn2+ complexes was determined using differential scanning calorimetry. We then determined the binding affinity between 4F2 and Zn2+ by using isothermal calorimetry. To further elucidate the molecular binding mechanism of 4F2 toward Zn2+, we applied the 1H–15N heteronuclear single quantum coherence NMR technique. We found that 4F2 recognized Zn2+ near the complementarity determining region 3 (CDR3). Our results provide the basis for the recognition mechanism of ZnO by 4F2.
Tracing the evolutionary history of the little‐known Mediterranean‐Macaronesian genus Andryala (Asteraceae) by multigene sequencing

Published: June 2015

AbstractAndryala (Asteraceae: Cichorieae) is a little‐known Mediterranean‐Macaronesian genus whose taxonomy is much in need of revision. In order to elucidate species relationships in the genus, we performed phylogenetic analyses of nucleotide sequences of the internal transcribed spacers (ITS) and the external transcribed spacer (ETS) of nuclear ribosomal DNA (nrDNA), two chloroplast (cpDNA) markers (trnT‐trnL and trnV‐ndhC intergenic spacers), and one single‐copy nuclear gene (sqs) using Bayesian and maximum parsimony methods of inference. While cpDNA analysis confirmed a previously inferred chloroplast capture event with the sister genus Pilosella, all nuclear markers supported the monophyletic origin of Andryala. However, determining accurate phylogenetic relationships within the genus was quite challenging due to very low levels of nucleotide divergence of all nrDNA and cpDNA markers and a high degree of homoplasy and incomplete lineage sorting in the variable sqs marker. Although none of the phylogenies were well resolved, all markers identified two well‐supported basal lineages corresponding to the relict species A. agardhii (Spain, Morocco) and A. laevitomentosa (Romania). The remaining Andryala taxa under study, whose relationships were largely unresolved, formed a well‐supported clade (“Major Radiation Group”). The capacity of the markers to resolve taxonomic entities within this group varied. While congruent genetic evidence was found for some taxa, several morphologically unambiguous species could not be distinguished at all with most or even all markers. The extremely low level of genetic divergence among most of the species, in spite of high morphological diversity, along with a basal polytomy found with all markers, suggests their relatively recent and rapid speciation. Phylogenetic analyses of the single‐copy marker advocate for a single colonization event of the common ancestor of two endemic species (A. glandulosa, A. crithmifolia) from the Mediterranean region to Madeira and that of two other endemics (A. perezii, A. pinnatifida) to the Canary Islands. The frequently observed evolutionary pattern of continental dispersion followed by insular speciation also holds for Andryala.

Published: June 2015

AbstractThe classification of species‐rich genera is one of the most challenging tasks in systematics. In this paper we present an updated infrageneric classification of the genus Peperomia (Piperaceae), one of the most species‐rich genera of plants. The classification is based on a molecular phylogeny of 190 accessions and the placement of 1340 of the 1606 currently accepted taxa within this classification. We provide the most comprehensive circumscriptions of Peperomia subgenera since the work of Dahlstedt in 1900, with five newly described subgenera. Fourteen monophyletic groups were revealed by phylogenetic reconstructions, including two newly discovered clades. Extensive field work, monitoring of representative living collections in our botanical gardens, and herbarium studies were the basis for morphological assignment of 80% of Peperomia species to the subgenera recognized and described herein. This work, in combination with the detailed descriptions of these subgenera, will aid field botanists, taxonomists, and ecologists to properly collect and identify species. Although parallel evolution of characters makes identification of species within Peperomia difficult, especially in species‐rich clades, the key to subgenera will provide a useful framework for anyone interested in this genus and will be a reference for further studies in Peperomia.

Stock Ownership and Political Behavior: Evidence from Demutualizations
Authors: Kaustia Markku , Knüpfer Samuli , Torstila Sami 
Published: June 2015

A setting in which customer-owned mutual companies converted to publicly listed firms created a plausibly exogenous increase in stock ownership. We use this shock to identify the effect of ownership of publicly listed shares on political behavior. Using instrumental variable regressions, difference-in-differences analyses, and matching methods, we find the shock changed the way people vote in the affected areas, with the demutualizations being followed by a 1.7–2.7-percentage-point increase in right-of-center vote share. Analyses of demutualizations that did not involve public listing of shares suggest that explanations based on wealth, liquidity, and tax-related incentives do not drive the results, and that the ownership of publicly listed shares was instrumental in generating the increase in conservative voting.

Sourcing Strategies and Supplier Incentives for Short-Life-Cycle Goods
Authors: Calvo Eduard , Martínez-de-Albéniz Victor 
Published: June 2015

Multiple sourcing with quick response has been recognized as a useful tool to manage demand risk for short-life-cycle goods. However, general wisdom has traditionally ignored the effect of these practices on supplier incentives. In this paper we find that, when suppliers make pricing decisions, dual sourcing does not always lead to higher supply chain efficiency or buyer profits as compared to single sourcing. This loss takes place when suppliers commit to prices up front, before any possible forecast change, but not when they delay the price quotes after demand forecasts have been updated. Specifically, with up-front price commitment, dual sourcing leads to inflation of supplier prices because expensive suppliers will still receive part of the business if they are sufficiently quick. Thus, when supplier prices are endogenous, double marginalization may offset the additional buyer profit enabled by higher ordering flexibility. In contrast, with delayed price quotes, a buyer will find dual sourcing beneficial because single sourcing locks it into a monopolistic supplier that extracts most of the available rent.

Shelf lives: Drawing out letters from World War I
Authors: MacDonald Juliet 
Published: June 2015

Abstract
This article concerns the initial stages of an art residency with the Liddle Collection, an archive of World War I interviews, documents and related objects at Leeds University Library’s Special Collections. The Collection, which has been awarded Designation for its international significance, was founded by historian Peter Liddle in the 1970s, and is centred on personal testimonies of wartime experiences. After outlining its history and current situation, the article focuses on my modes of entry into this large body of material. The Collection has a catalogue and cross-referencing subject index. With reference to Spieker, I consider how they shape the archive as I encounter it. Three writing/drawing methods (making notes, drawing diagrams and writing lists) have been used as a means to immerse myself in the Collection, map and process it as an artist. Finally, I consider Christov-Bakargiev’s idea of the ‘distracted archive’ as a model to take forward.
