While the acceleration to high energies proceeds via the diffusive mechanism at the scales exceeding by far the shock width, the initial stage (injection) should occur at the shock itself. Numerical tracing of ions is done in a model quasi-perpendicular shock front with a typical interplanetary shock parameters (Mach number, upstream ion temperature). The analysis of the distribution of the transmitted solar wind is used to adjust the cross-shock potential which is not directly measured. It is found that, for typical upstream ion temperatures, acceleration of the ions from the tail of the solar wind distribution is unlikely. Pickup ions with a shell distribution are found to be effectively energized and may be injected into further diffusive acceleration regime. Pre-accelerated ions are efficiently upscaled in energies. A part of these ions is returned to the upstream region where they can further be diffusively accelerated.}, language = {en} } @article{NejadLangHahnetal.2013, author = {Nejad, B.

Hence, targeting the tumour microenvironment and its vasculature has evolved as a promising novel treatment strategy. The role of tumour neoangiogenesis in cutaneous B-cell lymphoma, however, has not yet been elucidated. Therefore, we examined the expression of vascular endothelial growth factor (VEGF) and its receptors VEGFR-1 and VEGFR-2, as well as microvessel density by immunohistochemistry in paraffin-embedded specimens of different subtypes of primary cutaneous B-cell lymphomas, systemic diffuse large B-cell lymphoma, and cutaneous B-cell pseudolymphoma. Primary cutaneous large B-cell lymphoma (PCLBCL) were characterized by significantly higher intratumoral expression levels of VEGF and its receptors in comparison with the indolent lymphoma subtypes. Moreover, PCLBCL exhibited significantly higher intratumoral microvessel counts. Our study provides evidence that the most aggressive subtype of cutaneous B-cell lymphoma, PCLBCL, is characterized by a proangiogenic micromilieu.}, language = {en} } @article{PoppeBroeckerTrautmann2013, author = {Poppe, Lidia M. and Br{\"o}cker, Eva-Bettina and Trautmann, Axel}, title = {The One-nail Brown Band: Macro- and Micro-morphology}, series = {Acta Dermato-Venereologica}, volume = {93}, journal = {Acta Dermato-Venereologica}, number = {4}, doi = {10.2340/00015555-1505}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-128566}, pages = {479-480}, year = {2013}, abstract = {No abstract available.}, language = {en} } @article{Schneider2013, author = {Schneider, Peter}, title = {Paradigm Shift}, series = {Deutsches {\"A}rzteblatt International}, volume = {110}, journal = {Deutsches {\"A}rzteblatt International}, number = {22}, doi = {10.3238/arztebl.2013.0401a}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-128858}, pages = {401}, year = {2013}, abstract = {No abstract available.}, language = {en} } @article{MuellenbachRoewerKranke2013, author = {M{\"u}llenbach, Ralf Michael and Roewer, Norbert and Kranke, Peter}, title = {Quality Assurance Would Be Welcome}, series = {Deutsches {\"A}rzteblatt international}, volume = {110}, journal = {Deutsches {\"A}rzteblatt international}, number = {27-28}, doi = {10.3238/arztebl.2013.0485a}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-128844}, pages = {485}, year = {2013}, abstract = {No abstract available.}, language = {en} } @article{vanOorschotRadesLordick2013, author = {van Oorschot, Birgitt and Rades, Dirk and Lordick, Florian}, title = {Connections Are Clearly More Complex}, series = {Deutsches {\"A}rzteblatt international}, volume = {110}, journal = {Deutsches {\"A}rzteblatt international}, number = {44}, doi = {10.3238/arztebl.2013.0753a}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-128837}, pages = {753}, year = {2013}, abstract = {No abstract available.}, language = {en} } @article{KressHuettenhoferLandryetal.2013, author = {Kress, Michaela and H{\"u}ttenhofer, Alexander and Landry, Marc and Kuner, Rohini and Favereaux, Alexandre and Greenberg, David and Bednarik, Josef and Heppenstall, Paul and Kronenberg, Florian and Malcangio, Marzia and Rittner, Heike and {\"U}{\c{c}}eyler, Nurcan and Trajanoski, Zlatko and Mouritzen, Peter and Birklein, Frank and Sommer, Claudia and Soreq, Hermona}, title = {microRNAs in nociceptive circuits as predictors of future clinical applications}, series = {Frontiers in Molecular Neuroscience}, volume = {6}, journal = {Frontiers in Molecular Neuroscience}, number = {33}, doi = {10.3389/fnmol.2013.00033}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-154597}, year = {2013}, abstract = {Neuro-immune alterations in the peripheral and central nervous system play a role in the pathophysiology of chronic pain, and non-coding RNAs - and microRNAs (miRNAs) in particular - regulate both immune and neuronal processes. Specifically, miRNAs control macromolecular complexes in neurons, glia and immune cells and regulate signals used for neuro-immune communication in the pain pathway. Therefore, miRNAs may be hypothesized as critically important master switches modulating chronic pain. In particular, understanding the concerted function of miRNA in the regulation of nociception and endogenous analgesia and defining the importance of miRNAs in the circuitries and cognitive, emotional and behavioral components involved in pain is expected to shed new light on the enigmatic pathophysiology of neuropathic pain, migraine and complex regional pain syndrome. Specific miRNAs may evolve as new druggable molecular targets for pain prevention and relief. Furthermore, predisposing miRNA expression patterns and inter-individual variations and polymorphisms in miRNAs and/or their binding sites may serve as biomarkers for pain and help to predict individual risks for certain types of pain and responsiveness to analgesic drugs. miRNA-based diagnostics are expected to develop into hands-on tools that allow better patient stratification, improved mechanism-based treatment, and targeted prevention strategies for high risk individuals.}, language = {en} } @unpublished{WeithmannKlug2013, author = {Weithmann, Sabrina and Klug, Stefan}, title = {Integrative Sustainable Concepts for Individual Mobility in Asia - A Qualitative Analysis of Carsharing and Taxi Services in Singapore}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-145982}, year = {2013}, abstract = {Singapore has a unique and proactive approach towards managing the national transport system. This article explores the integrative approach of carsharing into the overall transport system from an individual sustainable mobility perspective. The authors argue that for Singapore, taxi services are the strongest competitor for the establishment of free-floating carsharing systems. Low taxi fares and a high distribution rate provide easy access for consumers and show great advantages in correspondence with the prevalent transport measures. Furthermore, the Singaporean government considers taxi services as part of public transport that helps bridging public transportation gaps in door-to-door travel. The article draws on literature review and expert interviews to evaluate the current market conditions and analyse the pros and cons of carsharing systems and taxi services as integrated part of the public transport system. The authors conclude by stating that from a sustainable perspective, the goal is to replace private car ownership.

Regional, mainly liver-directed, therapies may induce limited tumor responses but do not improve overall survival. Response rates of metastatic uveal melanoma (MUM) to systemic chemotherapy are poor. Insights into the molecular biology of MUM recently led to investigation of new drugs. In this study, to compare response rates of systemic treatment for MUM we searched Pubmed/Web of Knowledge databases and ASCO website (1980-2013) for "metastatic/uveal/melanoma" and "melanoma/eye." Forty studies (one case series, three phase I, five pilot, 22 nonrandomized, and two randomized phase II, one randomized phase III study, data of three expanded access programs, three retrospective studies) with 841 evaluable patients were included in the numeric outcome analysis. Complete or partial remissions were observed in 39/841 patients (overall response rate [ORR] 4.6\%; 95\% confidence intervals [CI] 3.3-6.3\%), no responses were observed in 22/40 studies. Progression-free survival ranged from 1.8 to 7.2, median overall survival from 5.2 to 19.0 months as reported in 21/40 and 26/40 studies, respectively. Best responses were seen for chemoimmunotherapy (ORR 10.3\%; 95\% CI 4.8-18.7\%) though mainly in first-line patients. Immunotherapy with ipilimumab, antiangiogenetic approaches, and kinase inhibitors have not yet proven to be superior to chemotherapy. MEK inhibitors are currently investigated in a phase II trial with promising preliminary data. Despite new insights into genetic and molecular background of MUM, satisfying systemic treatment approaches are currently lacking. Study results of innovative treatment strategies are urgently awaited.}, language = {en} }
