Role of sclerotherapy in vascular malformations
Authors: Mattassi R. 
Published: April 2017

SummaryCongenital vascular malformations (CVM) are a heterogeneous group of vessels defects that include venous, lymphatic, arteriovenous and combined anomalies. CVM may be located in every part of the body with great variability. A precise diagnostic process is required to get complete information about the anomaly prior to decide treatment between different options: surgery, sclerotherapy, embolization and laser. Sclerotherapy has a role in each type of CVM. However, correct indication, selection of the best sclerosing agent, and knowledge of technical skills in CVM are required for a good result. In venous malformations, ethanol is the most effective sclerosing agent but experience in management is required. Lymphatic malformations, mainly in the macrocystic form, can be treated easily with different substances. The nidus of arteriovenous malformations can be occluded by alcohol sclerosis. However, because of the high hemodynamic of AVM, treatment may be difficult; a good sclerosing technique is necessary to avoid complications and to get good results, which are always possible.
Sclerotherapy technique in CHIVA strategy
Authors: Cappelli M. , Mendoza E. 
Published: April 2017

SummaryCHIVA has been developed by Claude France-schi in the 1980-es and was first published in 1988 (1). CHIVA is a strategy to treat venous insufficiency keeping the drainage through the saphenous veins and reentry perforating veins. Venous recirculations are stratified into shunt types depending on the origin of the reflux and the distal reentry to the deep veins (2). Originally the method was described with surgical interventions: Flush ligation of the saphenous veins from the deep veins (crossotomy), flush ligation of the tributaries at the saphenous trunk, disconnection of the refluxive saphenous trunk distal to a reentryperforating vein, disconnection of a refluxive perforating vein, if it is the proximal insufficiency point. Techniques in phlebology have developed: in the field of the vein ablating strategies (originally stripping) new possibilities are currently used, as foaming under ultrasound-guidance of the complete saphenous vein, and endoluminal heat techniques, as well as glue. In the same way, the CHIVA strategy has incorporated new techniques. This article highlights the application of foam sclero-therapy in combination with the CHIVA strategy. Sometimes in CHIVA it is useful to start with one step and complete the treatments months later, if a vein did not reduce its caliper or revert its flow after the first step.
Sclerotherapy of varicose veins
Authors: Schadeck M. 
Published: April 2017

SummaryHistorically, sclerotherapy is quite old, however, nowadays it is a common treatment in varicose therapy. It is a good and effective alternative to surgical and thermic treatment options regarding larger varicose veins and applicable for all forms of varices. With about 14,000 treatments per day, sclerotherapy is the most employed and cost effective technique worldwide.
Ultrasound-guided foam sclero -therapy of the small saphenous vein
Authors: Murena-Schmidt R. D. 
Published: April 2017

SummaryUltrasound guided sclerotherapy (UGFS) of varicose veins is a worldwide spread method, in many countries recognized by guidelines. Important for the outcome is the patients history, clinical investigation and a detailed colour coded ultrasound mapping previous to UGFS.In previous studies varicose small saphenous vein (SSV) treatment with UGFS were reported to have worse results compared to GSV. Other studies report good outcome after UGFS of SSV varicose veins up to 12 months follow up.In my experience UGFS of insufficient SSV is safe and effective with high patient‘s satisfaction, good longterm results and improvement in quality of life. UGFS can be used in all age groups. UGFS has the additional benefit that repeated treatments are easy to perform if needed and that this method is very cost effective. Treatment sessions last 20 to 30 minutes so that patients do not need significant time off work.
Do Superstitious Traders Lose Money?

Published: April 2017

Do superstitious traders lose money? We answer this question in the context of trading in the Taiwan Futures Exchange, where we exploit the Chinese superstition that the number 8 is lucky and the number 4 is unlucky. We find that individual investors, but not institutional investors, submit disproportionately more limit orders at 8 than at 4. This imbalance, defined as the “superstition index” for each investor, is positively correlated with trading losses. Superstitious investors lose money mainly because of their bad market timing and stale orders. Nevertheless, the reliance on number superstition for limit order submissions does decrease with trading experience.The online appendix is available at https://doi.org/10.1287/mnsc.2016.2701 .This paper was accepted by Amit Seru, finance.
Sonochemistry production of ZnO and zero-valent Fe nanoparticles from solutions of electric arc furnace dust leaching
Authors: Brunelli Katya , Cerchier Pietrogiovanni , Bonora Renato , Dabalà Manuele 
Published: April 2017

Abstract
In this work, nanoparticles of ZnO and zero-valent Fe were sonochemically synthesised using a solution produced from electric arc furnace dust leaching as raw material. The leaching was previously carried out using ultrasound with various concentrations of sulphuric acid. The resulting solutions contained, in addition to varying amounts of Zn and Fe, elements such as Cr, Mn, Mg, Ca, and Si. Two methods were developed, one for Fe and one for ZnO, to obtain the nanoparticles and to avoid the precipitation of the additional elements during the nanoparticle production. The synthesis of ZnO nanoparticles was performed through the formation of a precursor by sonochemical reaction with NaOH, and the thermal decomposition of this precursor by heating in furnace. The production of Fe nanoparticles involved the precipitation of FeOOH, the dissolution of FeOOH in HCl solution, and the ultrasound-assisted reduction of the iron ions with NaBH4. The nanoparticles were characterised by scanning and transmission electron microscopy, X-ray diffraction, X-ray fluorescence, and UV spectroscopy. The nanoparticles of Fe had a particle size of 6 nm and resulted in zero-valent Fe, whereas the ZnO nanoparticles were between 30 and 50 nm.

Abstract
A dynamic elastoplastic compression model of Norway spruce for virtual computer optimization of mechanical pulping processes was developed. The empirical wood behaviour was fitted to a Voigt-Kelvin material model, which is based on quasi static compression and high strain rate compression tests (QSCT and HSRT, respectively) of wood at room temperature and at high temperature (80–100°C). The effect of wood fatigue was also included in the model. Wood compression stress-strain curves have an initial linear elastic region, a plateau region and a densification region. The latter was not reached in the HSRT. Earlywood (EW) and latewood (LW) contributions were considered separately. In the radial direction, the wood structure is layered and can well be modelled by serially loaded layers. The EW model was a two part linear model and the LW was modelled by a linear model, both with a strain rate dependent term. The model corresponds well to the measured values and this is the first compression model for EW and LW that is based on experiments under conditions close to those used in mechanical pulping.
The Economics of GM Labeling and Implications for Trade
Authors: McCluskey Jill J. , Winfree Jason 
Published: April 2017

Abstract
In this article, we model the effects of both voluntary and mandatory genetically modified (GM) food labeling on profits and consumer welfare. The non-GM firms weakly benefit from having the option to voluntarily label their product and will increase their quantities produced if labeling makes their non-GM product more valuable to consumers relative to the increased costs of labeling. GM producers make lower profits when non-GM firms voluntarily label because of increase in non-GM firms production. Mandatory labeling can be a different scenario. Costs of mandatory labeling are borne by the GM producers, and the benefits are reaped by the non-GM producers as it differentiates their product. We also consider the possibility that consumers will view the mandatory GM labels as a warning, such as a mandatory health label on cigarettes. The combination of increased costs along with decreased willingness to pay could be damaging to GM producers. The level of consumer concern about consuming GM food greatly affects the impact of labeling policies. Coordination of policies for a trade agreement will have different effects depending on consumer risk perceptions in that country and the number of GM firms.
Inverted pyramid of prenatal care – is it enough? Should it be – extended inverted pyramid of prenatal care?
Authors: Ljubić Aleksandar 
Published: April 2017

Abstract
In recent years, the idea of the inverted pyramid of prenatal care and monitoring has emerged, for the purpose of prediction and prevention, early detection and treatment of health disorders of the fetus. Is this enough? If we analyze the period behind us, progress has been made in the field of detection of multiple pregnancies, dating of pregnancy and prenatal detection of chromosomal and structural fetal disorders, as well as a small amount of progress in terms of prediction and prevention of preeclampsia. If these disorders are the consequence of the disturbed or dysfunctional placentation, they are rooted at the time of implantation. This means that the changes that lead to the dysfunctional implantation should be sought in the pre-implantation period, in relation between the embryo and the endometrium. An extended inverted pyramid is necessary to find better results in perinatal medicine. This means that the interventions should be focused on the preconception and peri-implantation periods. The therapy should be on the subcellular and genetic level by applying the latest biotechnological procedures. It is possible that the time is approaching when the listed disorders of a pregnancy will be the indications for the application of a non stimulated in-vitro fertilization (IVF) (without ovary stimulating medication) with the use of new biotechnological achievements.

Published: April 2017

Abstract
The γ-region of the Mn–Al phase diagram between 45 and 70 at.% Al was re-investigated by a combination of powder and single crystal X-ray diffraction as well as EDS analysis to establish the distribution of Mn and Al atoms. Single crystals of γ-Mn5–x
Al8+x
were grown using Sn-flux at 650 °C. The crystal structure, atomic coordinates and site occupancy parameters of γ-Mn5−x
Al8+x
phases were refined from single crystal X-ray data. The γ-Mn5-x
Al8+x
phase adopts the rhombohedral Cr5Al8-type structure rather than a cubic γ-brass structure. The refined compositions from two crystals extracted from the Al-rich and Mn-rich sides are, respectively, Mn4.76Al8.24(2)
(I) and Mn6.32Al6.68(2)
(II). The structure was refined in the acentric R3m space group (No.160, Z=6), in order to compare with other reported rhombohedral γ-brasses. In addition, according to X-ray powder diffraction analysis, at the Al-rich side the γ-phase coexists with LT–Mn4Al11 and, at the Mn-rich side, with a hitherto unknown phase. The refined lattice parameters from powder patterns fall in the range a=12.6814(7)−12.6012(5) Å and c=7.9444(2)−7.9311(2) Å from Al-rich to Mn-rich loadings, and the corresponding rhombohedral angles distorted from a pseudo-cubic cell were found to be 89.1(1)°−88.9(1)°. Magnetic susceptibility and magnetization studies of Mn4.92Al8.08(2) are consistent with moment bearing Mn and suggest a spin glass state below 27 K. Tight-binding electronic structure calculations (LMTO-ASA with LSDA) showed that the calculated Fermi level for γ-“Mn5Al8” falls within a pseudogap of the density of states, a result which is in accordance with a Hume-Rothery stabilization mechanism γ-brass type phases.

Authors: Gärtner Judith 
Published: April 2017

Zusammenfassung:
In der alttestamentlichen Tradition sind Flucht und Migration zentrale Themen, die über die Jahrhunderte der Entstehung der alttestamentlichen Literatur reflektiert und facettenreich diskutiert worden sind. Dabei erfährt die Reflexion von Fremdsein, Flucht und Migration im Laufe der Geschichte des antiken Israel aufgrund der sich wandelnden politischen, kulturellen und sozioökonomischen Rahmenbedingungen bedeutende Transformationsprozesse. Dieser Prozess wird am Beispiel der Sozialgesetzgebung im Bundesbuch, der Reflexion des Lebens im Exil sowie der Auseinandersetzung über den Umgang mit Fremden in der neuformierten judäischen Gemeinschaft in nachexilischer Zeit skizziert.
Transnationale religiöse Praktiken in der Migrationsgesellschaft: historisch – soziologisch – unterrichtspraktisch
Authors: Käbisch David 
Published: April 2017

Zusammenfassung:
Die meisten Migranten partizipieren an transnationalen sozialen Praktiken, indem sie zwischen dem Herkunfts- und Zielland hin- und herreisen, über soziale Medien miteinander kommunizieren sowie religiöse Ideen und Traditionen transferieren. In einer transnationalen Forschungsperspektive ist es daher folgerichtig, die vielfältigen Beziehungen und Sozialräume zwischen ‚hier‘ und ‚dort‘ zu untersuchen. Mit Bezug auf den Ansatz der Beziehungsgeschichte und Kulturtransferforschung bietet der Artikel einen Überblick über transnationale religiöse Praktiken, wie sie in Migrationsfamilien und -gemeinden zu finden sind. Darüber hinaus skizziert der Beitrag Konsequenzen, die sich aus der transnationalen Perspektive für den Religionsunterricht ergeben.

Abstract
Stone, JD, Kreutzer, A, Mata, JD, Nystrom, MG, Jagim, AR, Jones, MT, and Oliver, JM. Changes in creatine kinase and hormones over the course of an American Football Season. J Strength Cond Res 33(9): 2481–2487, 2019—The purpose of this study was to examine changes in creatine kinase and hormones over the course of an entire season of American football. A secondary purpose was to determine differences between starters and nonstarters. Fasting blood samples were obtained from 19 National Collegiate Athletic Association Division I (n = 19; 20 ± 1 years) football athletes over the course of a season beginning before the start of summer off-season conditioning (T1), before (T2) and after preseason (T3) football camp, with remaining samples taken throughout the competitive season (T4-T8). A magnitude-based inference approach was used to define outcomes. Testosterone was higher in starters before the start of the season (T1, Effect Size [ES] = 0.8) and during preconference (T4; ES = 0.7). Postcamp (T3) testosterone was lower in all players, though greater in starters (starters, 0.0%/0.3%/99.7%; nonstarters, 0.2%/2.9%/96.9%). An increase cortisol relative to baseline (T1) was observed in starters early in season (T4, ES = 0.7; T5, ES = 0.5). Creatine kinase was elevated at all time points in all athletes, with starters having higher circulating levels throughout season. These data demonstrate that changes in hormonal markers may be experienced over a season of football and differ by playing status. Differences between starters and nonstarters may be indicative of greater damage and stress experienced by starters, which may result from a greater number of repetitions.
Correlates of Perceptual Orientation Biases in Human Primary Visual Cortex
Authors: Patten Matthew L. , Mannion Damien J. , Clifford Colin W.G. 
Published: April 2017

Vision can be considered as a process of probabilistic inference. In a Bayesian framework, perceptual estimates from sensory information are combined with prior knowledge, with a stronger influence of the prior when the sensory evidence is less certain. Here, we explored the behavioral and neural consequences of manipulating stimulus certainty in the context of orientation processing. First, we asked participants to judge whether a stimulus was oriented closer to vertical or the clockwise primary oblique (45°) for two stimulus types (spatially filtered noise textures and sinusoidal gratings) and three manipulations of certainty (orientation bandwidth, contrast, and duration). We found that participants consistently had a bias toward reporting orientation as closer to 45° during conditions of high certainty and that this bias was reduced when sensory evidence was less certain. Second, we measured event-related fMRI BOLD responses in human primary visual cortex (V1) and manipulated certainty via stimulus contrast (100% vs 3%). We then trained a multivariate classifier on the pattern of responses in V1 to cardinal and primary oblique orientations. We found that the classifier showed a bias toward classifying orientation as oblique at high contrast but categorized a wider range of orientations as cardinal for low-contrast stimuli. Orientation classification based on data from V1 thus paralleled the perceptual biases revealed through the behavioral experiments. This pattern of bias cannot be explained simply by a prior for cardinal orientations.SIGNIFICANCE STATEMENTOur perception of the world around us is biased through prior expectations rather than necessarily reflecting the true state of our environment. Here, we investigate biases in the visual processing of spatial orientation to understand how prior expectations and current sensory information interact to generate a percept. By degrading visual input in various ways, we are able to quantify the extent to which prior experience affects both perceptual judgments and neural responses in the human visual system. We observe systematic biases in the perception of orientation that correlate with the pattern of activity in the primary visual cortex of the human brain. These results indicate that prior expectations influence neural processing right from the earliest stage of the cortical hierarchy.
Prophylactic Early Erythropoietin for Neuroprotection in Preterm Infants: A Meta-analysis
Authors: Fischer Hendrik S. , Reibel Nora J. , Bührer Christoph , Dame Christof 
Published: April 2017

CONTEXT:Recombinant human erythropoietin (rhEPO) is a promising pharmacological agent for neuroprotection in neonates.OBJECTIVE:To investigate whether prophylactic rhEPO administration in very preterm infants improves neurodevelopmental outcomes in a meta-analysis of randomized controlled trials (RCTs).DATA SOURCES:Medline, Embase, and the Cochrane Central Register of Controlled Trials were searched in December 2016 and complemented by other sources.STUDY SELECTION:RCTs investigating the use of rhEPO in preterm infants versus a control group were selected if they were published in a peer-reviewed journal and reported neurodevelopmental outcomes at 18 to 24 months’ corrected age.DATA EXTRACTION:Data extraction and analysis followed the standard methods of the Cochrane Neonatal Review Group. The primary outcome was the number of infants with a Mental Developmental Index (MDI) &lt;70 on the Bayley Scales of Infant Development. Secondary outcomes included a Psychomotor Development Index &lt;70, cerebral palsy, visual impairment, and hearing impairment.RESULTS:Four RCTs, comprising 1133 infants, were included in the meta-analysis. Prophylactic rhEPO administration reduced the incidence of children with an MDI &lt;70, with an odds ratio (95% confidence interval) of 0.51 (0.31–0.81), P &lt; .005. The number needed to treat was 14. There was no statistically significant effect on any secondary outcome.CONCLUSIONS:Prophylactic rhEPO improved the cognitive development of very preterm infants, as assessed by the MDI at a corrected age of 18 to 24 months, without affecting other neurodevelopmental outcomes. Current and future RCTs should investigate optimal dosing and timing of prophylactic rhEPO and plan for long-term neurodevelopmental follow-up.
