Focused electron beam induced deposition (FEBID) is a direct-write nanofabrication technique able to pattern three-dimensional magnetic nanostructures at resolutions comparable to the characteristic magnetic length scales. FEBID is thus a powerful tool for 3D nanomagnetism which enables unique fundamental studies involving complex 3D geometries, as well as nano-prototyping and specialized applications compatible with low throughputs. In this focused review, we discuss recent developments of this technique for applications in 3D nanomagnetism, namely the substantial progress on FEBID computational methods, and new routes followed to tune the magnetic properties of ferromagnetic FEBID materials. We also review a selection of recent works involving FEBID 3D nanostructures in areas such as scanning probe microscopy sensing, magnetic frustration phenomena, curvilinear magnetism, magnonics and fluxonics, offering a wide perspective of the important role FEBID is likely to have in the coming years in the study of new phenomena involving 3D magnetic nanostructures.

Background: Patient information materials and decision aids are essential tools for helping patients make informed decisions and share in decision-making. The aim of this study was to investigate the quality of the written patient information materials available at general practices in Styria, Austria.
Methods: We asked general practitioners to send in all patient information materials available in their practices and to answer a short questionnaire. We evaluated the materials using the Ensuring Quality Information for Patients (EQIP-36) instrument.
Results: A total of 387 different patient information materials were available for quality assessment. These materials achieved an average score of 39 out of 100. The score was below 50 for 78% of all materials. There was a significant lack of information on the evidence base of recommendations. Only 9 % of the materials provided full disclosure of their evidence sources. We also found that, despite the poor quality of the materials, 89% of general practitioners regularly make active use of them during consultations with patients.
Conclusion: Based on international standards, the quality of patient information materials available at general practices in Styria is poor. The vast majority of the materials are not suitable as a basis for informed decisions by patients. However, most Styrian general practitioners use written patient information materials on a regular basis in their daily clinical practice. Thus, these materials not only fail to help raise the health literacy of the general population, but may actually undermine efforts to enable patients to make shared informed decisions. To increase health literacy, it is necessary to make high quality, evidence-based and easy-to-understand information material available to patients and the public. For this, it may be necessary to set up a centralized and independent clearinghouse.
Die mediane Sternotomie ist in der Kardio-Chirurgie der wichtigste Zugang zum Herzen. Postoperative Wundheilungsstörungen in diesem Bereich sind seltene, jedoch gefürchtete Komplikationen, die zu schwerwiegenden Konsequenzen führen können. Die zunächst einfache oberflächliche Wundheilungsstörung kann sich verkomplizieren und über eine Osteomyelitis des Sternums zu einer Mediastinitis mit eventuell letalen Konsequenzen führen. Aktuell geben unterschiedliche Autoren eine Inzidenz von 1 % – 8 % an. Die Mortalität der Sternumosteitis wird dabei zwischen 10 % und 30 % angegeben. Wird der Pathomechanismus der Erkrankung zu einem Algorithmus zusammengefasst, so kann sich über einen descendierenden Verlauf eine oberflächliche Wundheilungsstörung zu einer Sternumosteitis und schließlich zu einer Mediastinitis entwickeln. Natürlich kann sich die Infektion auch ascendierend ausbreiten. Über eine Infektion des Mediastinums oder des Sternums kann sich eine Infektion über die Weichteile bis an die Körperoberfläche ausdehnen. Der typische Patient, der eine Wundheilungsstörung erleidet ist in aller Regel polymorbide. Besonders bei diesem Patientenkollektiv sind eine kurze Behandlungsdauer und eine schnelle, postoperative Rehabilitation für das Ergebnis vorrangig. Ist der gewählte Therapieplan nicht aggressiv genug, so kommt es häufig zu chronischen Erkrankungen mit Fistelungen und einem konsekutiven Fortschreiten der Infektion in Weichteilen und Knochen. Neben medizinischen Gesichtspunkten kommen auch der wirtschaftliche Aspekte zu tragen. Wiederholte Operationen, lange Liegezeiten auf der Intensivstation und wiederholte sowie langwierige Rehabilitationsphasen sind nur wenige Beispiele der kostenintensiven Therapiebestandteile. Aufgrund der schwer beherrschbaren Infektsituation ist eine konsequent aggressive, definitive und zuverlässige Versorgung der infizierten Wunden von höchster Priorität. Dabei spielt es keine Rolle, ob es sich dabei um Wundheilungsstörungen im Bereich der Haut- und Unterhautweichteile, des Sternums oder des Mediastinums handelt. Zur Behandlung der Wundheilungsstörung nach medianer Sternotomie existieren verschiedene Behandlungsansätze und Therapieoptionen. Diese reichen von einfachen Debridements mit Sekundärvernähungen über Spül-Saug-Drainagen mit Antibiotika versetzen Lösungen bis hin zu Sternumteilresektionen, Vakuumverbänden und komplexen Lappenplastiken. ...
W±-boson production in p–Pb collisions at √sNN = 8.16 TeV and Pb–Pb collisions at √sNN = 5.02 TeV
(2022)
The production of the W± bosons measured in p−Pb collisions at a centre-of-mass energy per nucleon−nucleon collision sNN−−−−√=8.16 TeV and Pb−Pb collisions at sNN−−−−√=5.02 TeV with ALICE at the LHC is presented. The W± bosons are measured via their muonic decay channel, with the muon reconstructed in the pseudorapidity region −4<ημlab<−2.5 with transverse momentum pμT>10 GeV/c. While in Pb−Pb collisions the measurements are performed in the forward (2.5<yμcms<4) rapidity region, in p−Pb collisions, where the centre-of-mass frame is boosted with respect to the laboratory frame, the measurements are performed in the backward (−4.46<yμcms<−2.96) and forward (2.03<yμcms<3.53) rapidity regions. The W− and W+ production cross sections, lepton-charge asymmetry, and nuclear modification factors are evaluated as a function of the muon rapidity. In order to study the production as a function of the p−Pb collision centrality, the production cross sections of the W− and W+ bosons are combined and normalised to the average number of binary nucleon−nucleon collision ⟨Ncoll⟩. In Pb−Pb collisions, the same measurements are presented as a function of the collision centrality. Study of the binary scaling of the W±-boson cross sections in p−Pb and Pb−Pb collisions is also reported. The results are compared with perturbative QCD (pQCD) calculations, with and without nuclear modifications of the Parton Distribution Functions (PDFs), as well as with available data at the LHC. Significant deviations from the theory expectations are found in the two collision systems, indicating that the measurements can provide additional constraints for the determination of nuclear PDF (nPDFs) and in particular of the light-quark distributions.

Rechtswörterbücher beschränken sich für gewöhnlich auf die Erläuterung einer Vielzahl von Begriffen und Instituten des geltenden Rechts. Das gilt jedenfalls für die in Deutschland gängigen Werke. Sie reihen die Erklärung einzelner Rechtsbegriffe nach den herkömmlichen Definitionen aneinander, ohne die Grundlagen unseres Rechtsdenkens zutage treten zu lassen. Nicht so verfährt das hier anzuzeigende, von Denis Alland und Stéphane Rials herausgegebene und im Jahre 2003 in Paris erschienene Dictionnaire de la culture juridique. Es tritt mit dem Anspruch an, das Recht nicht nur als große Ansammlung von rechtsdogmatischen Begriffen zu präsentieren, sondern seine geschichtlichen und vor allem philosophischen Bezüge zu verdeutlichen. Damit sollen Zusammenhänge wiederhergestellt werden, die durch die Reduktion der Jurisprudenz auf eine reine Technik in den letzten Jahren zunehmend verloren gegangen sind. Die innerhalb des Dictionnaire zusammengetragene Stofffülle ist äußerst beeindruckend: Auf mehr als 1600 Seiten vereinigt das Werk insgesamt 409 Artikel aus der Feder von nicht weniger als 213 durchweg angesehenen juristischen Autoren, die ganz überwiegend aus Frankreich stammen. ...
Xenocoumacin (Xcn) 1 and 2 are the major antibiotics produced by the insect-pathogenic bacterium Xenorhabdus nematophila. Although the antimicrobial activity of Xcns has been explored, research regarding their action on mammalian cells is lacking. We aimed to investigate the action of Xcns in the context of inflammation and angiogenesis. We found that Xcns do not impair the viability of primary endothelial cells (ECs). Particularly Xcn2, but not Xcn1, inhibited the pro-inflammatory activation of ECs: Xcn2 diminished the interaction between ECs and leukocytes by downregulating cell adhesion molecule expression and blocked critical steps of the NF-κB activation pathway including the nuclear translocation of NF-κB p65 as well as the activation of inhibitor of κBα (IκBα) and IκB kinase β (IKKβ). Furthermore, the synthesis of pro-inflammatory mediators and enzymes, nitric oxide (NO) production and prostaglandin E2 (PGE2), inducible NO synthase (iNOS), and cyclooxygenase-2 (COX-2), was evaluated in leukocytes. The results showed that Xcns reduced viability, NO release, and iNOS expression in activated macrophages. Beyond these anti-inflammatory properties, Xcn2 effectively hindered pro-angiogenic processes in HUVECs, such as proliferation, undirected and chemotactic migration, sprouting, and network formation. Most importantly, we revealed that Xcn2 inhibits de novo protein synthesis in ECs. Consequently, protein levels of receptors that mediate the inflammatory and angiogenic signaling processes and that have a short half-live are reduced by Xcn2 treatment, thus explaining the observed pharmacological activities. Overall, our research highlights that Xcn2 exhibits significant pharmacological in vitro activity regarding inflammation and angiogenesis, which is worth to be further investigated preclinically.
Germany has experienced a rise in xenophobic attacks since it began to welcome refugees from Syria and elsewhere. Sebastian Jäckle and Pascal D. König have mapped these attacks and drawn some striking conclusions about their causes. They were more common in regions with a strong far-right presence and fewer migrants. One attack also tended to spark others – as did condemnation of xenophobia by national leaders, and Islamist terror. Britain saw a similar spike in xenophobic crime after the referendum. The authors ask whether the UK can learn from Germany’s painful experience.
Background and Aim. Spontaneous bacterial peritonitis (SBP) is one of the most common complications of liver cirrhosis. Antibiotics are the main treatment regimen of SBP. Traditional Chinese medicine Xuebijing injection has been used in such patients. Our study aimed to overview the efficacy of Xuebijing injection combined with antibiotics for the treatment of SBP.
Method. We searched the PubMed, Embase, China National Knowledge Infrastructure, VIP, and Wanfang databases. The search items included "Xuebijing", "peritonitis", "liver cirrhosis", and "random" to identify all relevant randomized controlled trials (RCTs). The Cochrane risk of bias tool was used to assess the study quality. The odd ratios (ORs) with 95% confidence intervals (CIs) were calculated by using a random-effect model. Heterogeneity was also calculated.
Results. A total of 9 RCTs were included. The study quality was unsatisfied. The overall (OR = 2.95, 95% CI = 1.97–4.42, p<0.00001) and complete (OR = 2.18, 95% CI = 1.57–3.04, p<0.00001) responses were significantly higher in the Xuebijing injection combined with antibiotics group than the antibiotics alone group. The incidence of cirrhosis related complications, including hepatic encephalopathy and hepatorenal syndrome, was lower in the Xuebijing injection combined with antibiotics group than the antibiotics alone group. No significant heterogeneity was observed among studies.
Conclusion. Additional use of Xuebijing injection may improve the efficacy of antibiotics for the treatment of SBP in liver cirrhosis. However, due to a low level of current evidence, we did not establish any recommendation regarding the use of Xuebijing injection for the treatment of SBP.
