Electrochemical immunosensors are antibody-based affinity biosensors with a high impact on clinical, environmental, food, and pharmaceutical analysis. In general, the analytical performance of these devices is critically determined by the materials and reagents used for their construction, signal production and amplification. Dendrimers are monodisperse and highly branched polymers with three-dimensional structures widely employed as “soft” nanomaterials in electrochemical immunosensor technology. This review provides an overview on the state-of-the-art in dendrimer-based electrochemical immunosensors, focusing on those using polyamidoamine and poly (propylene imine) dendrimers. Special emphasis is given to the most original methods recently reported for the construction of immunosensor architectures incorporating dendrimers, as well as to novel sensing approaches based on dendrimer-assisted signal enhancement strategies.

Advanced Styrenic resins are being developed throughout the industry to bridge the properties gap between traditional HIPS (High Impact Polystyrene) and ABS (Acrylonitrile-Butadiene-Styrene copolymers) resins. These new resins have an unprecedented balance of high gloss and high impact energies. Dow Chemical's contribution to this area is based on a unique combination of rubber morphologies including labyrinth, onion skin, and core-shell rubber particles. This new resin, referred as a controlled morphology resin (CMR), was investigated to determine the toughening mechanism of this unique rubber morphology. This poster will summarize the initial studies of these resins using the double-notch four-point bend test of Su and Yee, tensile stage electron microscopy, and Poisson Ratio analysis of the fracture mechanism.

Abstract There are ∼7000 rare diseases affecting 30 000 000 individuals in the U.S.A. 95% of these rare diseases do not have a single Food and Drug Administration-approved therapy. Relatively, limited progress has been made to develop new or repurpose existing therapies for these disorders, in part because traditional funding models are not as effective when applied to rare diseases. Due to the suboptimal research infrastructure and treatment options for Castleman disease, the Castleman Disease Collaborative Network (CDCN), founded in 2012, spearheaded a novel strategy for advancing biomedical research, the ‘Collaborative Network Approach’. At its heart, the Collaborative Network Approach leverages and integrates the entire community of stakeholders — patients, physicians and researchers — to identify and prioritize high-impact research questions. It then recruits the most qualified researchers to conduct these studies. In parallel, patients are empowered to fight back by supporting research through fundraising and providing their biospecimens and clinical data. This approach democratizes research, allowing the entire community to identify the most clinically relevant and pressing questions; any idea can be translated into a study rather than limiting research to the ideas proposed by researchers in grant applications. Preliminary results from the CDCN and other organizations that have followed its Collaborative Network Approach suggest that this model is generalizable across rare diseases.

Abstract Pelvic fractures are relatively uncommon, and in workers’ compensation most pelvic fractures are the result of an acute, high-impact event such as a fall from a roof or an automobile collision. A person with osteoporosis may sustain a pelvic fracture from a lower-impact injury such as a minor fall. Further, major parts of the bladder, bowel, reproductive organs, nerves, and blood vessels pass through the pelvic ring, and traumatic pelvic fractures that result from a high-impact event often coincide with damaged organs, significant bleeding, and sensory and motor dysfunction. Following are the steps in the rating process: 1) assign the diagnosis and impairment class for the pelvis; 2) assign the functional history, physical examination, and clinical studies grade modifiers; and 3) apply the net adjustment formula. Because pelvic fractures are so uncommon, raters may be less familiar with the rating process for these types of injuries. The diagnosis-based methodology for rating pelvic fractures is consistent with the process used to rate other musculoskeletal impairments. Evaluators must base the rating on reliable data when the patient is at maximum medical impairment and must assess possible impairment from concomitant injuries.

Zusammenfassung.Hintergrund: Die Häufigkeit pflegewissenschaftlicher Beiträge aus dem deutschsprachigen Raum in Zeitschriften mit hohem Impact Factor gibt Hinweise auf die Teilhabe der Disziplin am internationalen Diskurs. Bisherige Analysen beschränken sich auf pflegewissenschaftliche Zeitschriften. Diese konstatieren eine Unterrepräsentanz experimenteller Studien und klinischer Themen. Ziel: Identifikation und Analyse der Publikationen von im deutschsprachigen Raum ansässigen Pflegewissenschaftlerinnen/Pflegewissenschaftlern in internationalen pflegerelevanten High Impact Journals. Methode: Mittels Journal Citation Reports wurden pflegerelevante Zeitschriftenkategorien identifiziert, in denen die nach dem 5-Jahres-Impact-Factor höchsten 10 % der Zeitschriften der Jahre 2010 bis 2014 ausgewählt wurden. Der Einschluss der Publikationen und die Datenextraktion erfolgten durch zwei unabhängige Personen. Ergebnisse: Durchsucht wurden 106939 Publikationen aus 126 Zeitschriften. Eingeschlossen wurden 100 Publikationen, an denen 114 Pflegewissenschaftler/-innen aus dem deutschsprachigen Raum insgesamt 229 Mal beteiligt sind. Insgesamt 42 % sind Beobachtungsstudien, 11 % sind experimentelle Studien. Die berichteten Themen sind mehrheitlich klinisch orientiert (55 %). Über 50 % sind in den letzten zwei Jahren publiziert worden. Schlussfolgerungen: Das pflegewissenschaftliche Publikationsaufkommen aus dem deutschsprachigen Raum in High Impact Journals ist gering. Eine Zunahme über den Beobachtungszeitraum ist zu verzeichnen. Im Gegensatz zu früheren Analysen zeigt sich ein höherer Anteil klinischer Forschung.
