  abstract  = {Ankn{\"u}pfend an Jan Dirk M{\"u}llers Studie 'Spielregeln f{\"u}r den Untergang' fragt der Beitrag nach jenen Verhaltensweisen im 'Nibelungenlied', mit denen die Katastrophe h{\"a}tte verhindert werden k{\"o}nnen. Im Zentrum des Beitrags steht Dietrich von Bern, der wiederholt Handlungsalternativen aufzeigt, die eine andere Entwicklung des Geschehens erm{\"o}glicht h{\"a}tten. Seine Spielregeln f{\"u}r ein {\"U}berleben funktionieren nur deshalb nicht, weil der Herr der Amelungen in der nibelungischen Welt keine Mitspieler findet, die sich dauerhaft an seine Regeln halten. Nach der Katastrophe werden seine Maximen jedoch best{\"a}tigt und anerkannt, wie die zeitgen{\"o}ssischen Reflexionen im Umfeld des Epos zeigen. In der ʻNibelungenklageʼ wird nicht nur r{\"u}ckblickend das Fehlverhalten einzelner Figuren getadelt, sondern erm{\"o}glichen die Anweisungen Dietrichs auch ein Weiterleben und die Gestaltung k{\"u}nftigen Geschehens. Um diese These zu st{\"u}tzen, werden zun{\"a}chst die f{\"u}r Dietrich relevanten Episoden des 'Nibelungenlieds' in chronologischer Folge untersucht und die jeweiligen Handlungsmaximen bestimmt, anschließend die Bedeutung und Bewertung seiner Spielregeln in der 'Klage' untersucht. Flankierend werden auch die Werke der historischen Dietrichepik herangezogen.},

  abstract  = {Background: Sorbents have been shown to adsorb iodinated radiocontrast media. Objective: In this study we describe a simple method to compare various sorbents in terms of capacity to adsorb radiocontrast media. Methods: Iodixanol solution was injected into columns filled with three types of sorbent at filtration velocities of increasing magnitude. Two variables of interest - contrast removal rate and matched iodine retention (MIR) - were calculated to measure the adsorption efficiency and the mass of contrast iodine adsorbed versus sorbent used, respectively. Results: The highest contrast removal and MIR for Porapak Q, CST 401 and Amberlite XAD4 were 41, 38 and 16\% (p = 0.22 and 0.0005 for comparisons between Porapak Q-CST 401 and CST 401-Amberlite XAD4) and 0.060, 0.055 and 0.024, respectively (p = 0.18 and 0.0008). Extrapolation to a clinical scenario may suggest that removal of 8 ml iodixanol could be achieved by masses of sorbents of 43, 47 and 107 g, respectively. Conclusion: In this study we set a benchmark for comparing the radiocontrast-adsorbing efficiency of polymer sorbents during first-pass experiments, using a readily available methodology.},

  abstract  = {Elimination of pathogenic autoantibodies by immunoadsorption (IA) has been described as an effective adjuvant treatment in severe bullous autoimmune diseases, especially in pemphigus. There is much less experience in the treatment of bullous pemphigoid (BP). BP was diagnosed in a 62-year-old Caucasian woman presenting a pruritic rash with multiple tense blisters. Standard treatments with topical and oral corticosteroids, steroid-sparing agents including dapsone, azathioprine, mycophenolate mofetil (MMF) and intravenous immunoglobulins were ineffective or had to be discontinued due to adverse events. An immediate clinical response could be achieved by two treatment cycles of adjuvant protein A immunoadsorption (PA-IA) in addition to continued treatment with MMF (2 g/day) and prednisolone (1 mg/kg/day). Tolerance was excellent. Clinical improvement remained stable after discontinuation of IA and went along with sustained reduction of circulating autoantibodies. Our data demonstrate that PA-IA might be a safe and effective adjuvant treatment in severe and recalcitrant BP.},

  abstract  = {Background: Bowen's disease (BD) of the nail unit is associated with human papillomavirus (HPV) infection. Objective: This study aimed to investigate the frequency of high-risk HPV infection, gender, age and digital distribution in this condition. Methods: Biopsy specimens of 3 consecutive cases with periungual BD were investigated for the presence of HPV DNA by in situ hybridization and by polymerase chain reaction (PCR). Furthermore, 74 cases of ungual BD conducted with HPV genotyping as reported in the literature were reviewed. Results: PCR of biopsy specimens revealed in 2 cases infection with HPV-16 and in 1 case with HPV-73. Additionally, in 1 HPV-16-positive case HPV-31/33 was detected by in situ hybridization. In line, review of the literature demonstrated a clear association of HPV-positive BD with high-risk HPV types. Interestingly, age at diagnosis was significantly lower in women. Whereas in both genders the second to fourth fingers on both hands were commonly diseased, only in men the thumbs were also prominently affected. Conclusions: Infection with high-risk HPV types is common in BD of the nail unit suggesting the aetiological cause. Therefore, patients and partners should be closely followed up for digital and genital HPV-associated lesions.},

  abstract  = {Primary prevention strategies, such as vaccinations at the age extremes, in neonates and elderly individuals, demonstrate a challenge to health professionals and public health specialists. The aspects of the differentiation and maturation of the adaptive immune system, the functional implications of immunological immaturity or immunosenescence and its impact on vaccine immunogenicity and efficacy will be highlighted in this review. Several approaches have been undertaken to promote Th1 responses in neonates and to enhance immune functions in elderly, such as conjugation to carrier proteins, addition of adjuvants, concomitant vaccination with other vaccines, change in antigen concentrations or dose intervals or use of different administration routes. Also, early protection by maternal vaccination seems to be beneficial in neonates. However, it also appears necessary to think of other end points than antibody concentrations to assess vaccine efficacy in neonates or elderly, as also the cellular immune response may be impaired by the mechanisms of immaturity, underlying health conditions, immunosuppressive treatments or immunosenescence. Thus, lifespan vaccine programs should be implemented to all individuals on a population level not only to improve herd protection and to maintain protective antibody levels and immune memory, but also to cover all age groups, to protect unvaccinated elderly persons and to provide indirect protection for neonates and small infants.},

Methods: Forty-six adults with a minimum of 6 months of cochlear implant experience were included. CIS+, HDCIS and FSP were compared in speech perception tests in noise, pitch scaling and questionnaires. The randomized tests were performed acutely (interval 1) and again after 3 months of FSP experience (interval 3). The subjective evaluation included questionnaire 1 at intervals 1 and 3, and questionnaire 2 at interval 2, 1 month after interval 1. Results: Comparison between FSP and CIS+ showed that FSP performed at least as well as CIS+ in all speech perception tests, and outperformed CIS+ in vowel and monosyllabic word discrimination. Comparison between FSP and HDCIS showed that both performed equally well in all speech perception tests. Pitch scaling showed that FSP performed at least as well as HDCIS. With FSP, sound quality was at least as good and often better than with HDCIS. Conclusions: Results indicate that FSP performs better than CIS+ in vowel and monosyllabic word understanding. Subjective evaluation demonstrates strong user preferences for FSP when listening to speech and music.},

  abstract  = {Electrophysiological analyses conducted about 25 years ago detected two types of anion channels in the plasma membrane of guard cells. One type of channel responds slowly to changes in membrane voltage while the other responds quickly. Consequently, they were named SLAC, for SLow Anion Channel, and QUAC, for QUick Anion Channel. Recently, genes SLAC1 and QUAC1/ALMT12, underlying the two different anion current components, could be identified in the model plant Arabidopsis thaliana. Expression of the gene products in Xenopus oocytes confirmed the quick and slow current kinetics. In this study we provide an overview on our current knowledge on slow and quick anion channels in plants and analyze the molecular evolution of ALMT/QUAC-like and SLAC-like channels. We discovered fingerprints that allow screening databases for these channel types and were able to identify 192 (177 non-redundant) SLAC-like and 422 (402 non-redundant) ALMT/QUAC-like proteins in the fully sequenced genomes of 32 plant species. Phylogenetic analyses provided new insights into the molecular evolution of these channel types. We also combined sequence alignment and clustering with predictions of protein features, leading to the identification of known conserved phosphorylation sites in SLAC1-like channels along with potential sites that have not been yet experimentally confirmed. Using a similar strategy to analyze the hydropathicity of ALMT/QUAC-like channels, we propose a modified topology with additional transmembrane regions that integrates structure and function of these membrane proteins. Our results suggest that cross-referencing phylogenetic analyses with position-specific protein properties and functional data could be a very powerful tool for genome research approaches in general.},

  abstract  = {The appearance of massless Dirac fermions in graphene requires two equivalent carbon sublattices of trigonal shape. While the generation of an effective mass and a band gap at the Dirac point remains an unresolved problem for freestanding extended graphene, it is well established by breaking translational symmetry by confinement and by breaking sublattice symmetry by interaction with a substrate. One of the strongest sublattice-symmetry-breaking interactions with predicted and measured band gaps ranging from 400 meV to more than 3 eV has been attributed to the interfaces of graphene with Ni and Co, which are also promising spin-filter interfaces. Here, we apply angle-resolved photoemission to epitaxial graphene on Ni (111) and Co(0001) to show the presence of intact Dirac cones 2.8 eV below the Fermi level. Our results challenge the common belief that the breaking of sublattice symmetry by a substrate and the opening of the band gap at the Dirac energy are in a straightforward relation. A simple effective model of a biased bilayer structure composed of graphene and a sublattice-symmetry-broken layer, corroborated by density-functional-theory calculations, demonstrates the general validity of our conclusions.},
