[Hand transplantation - fiction or reality?]

Hand transplantation has been indicated in selective patients after traumatic upper extremity amputation and only performed in a few centers around the world for the last decade. In comparison to solid organ transplantation, there is a challenge to overcome the host immunological barrier due to complex antigenicity of the different included tissues, the skin being the most susceptible to rejection. Patients require lifelong immunosuppression for non life-threatening conditions. Minimization of maintenance immunosuppression represents the key step for promoting wider applicability of hand transplantation. Current research is working towards the understanding mechanisms of composite tissue allograft (CTA) rejection. Worldwide, in 51 patients 72 hands (21 double hand transplants) and once both arms have been successfully transplanted since 1998.

Exploring Magic Realism in Salman Rushdie's Fiction

Kluwick breaks new ground in this book, moving away from Rushdie studies that focus on his status as postcolonial or postmodern, and instead considering the significance of magic realism in his fiction. Rushdie’s magic realism, in fact, lies at the heart of his engagement with the post/colonial. In a departure from conventional descriptions of magic realism—based primarily on the Latin-American tradition—Kluwick here proposes an alternative definition, allowing for a more accurate description of the form. She argues that it is disharmony, rather than harmony, that is decisive: that the incompatibility of the realist and the supernatural needs to be recognized as a driving force in Rushdie’s fiction. In its rigorous analysis of this Rushdian magic realism, this book considers the entire corpus—Midnight’s Children, Shame, The Satanic Verses, The Moor’s Last Sigh, The Ground Beneath Her Feet, Shalimar the Clown, and The Enchantress of Florence. This study is the first of its kind to do so.

Intervertebral disc regeneration or repair with biomaterials and stem cell therapy--feasible or fiction?

The "gold standard" for treatment of intervertebral disc herniations and degenerated discs is still spinal fusion, corresponding to the saying "no disc - no pain". Mechanical prostheses, which are currently implanted, do only have medium outcome success and have relatively high re-operation rates. Here, we discuss some of the biological intervertebral disc replacement approaches, which can be subdivided into at least two classes in accordance to the two different tissue types, the nucleus pulposus (NP) and the annulus fibrosus (AF). On the side of NP replacement hydrogels have been extensively tested in vitro and in vivo. However, these gels are usually a trade-off between cell biocompatibility and load-bearing capacity, hydrogels which fulfill both are still lacking. On the side of AF repair much less is known and the question of the anchoring of implants is still to be addressed. New hope for cell therapy comes from developmental biology investigations on the existence of intervertebral disc progenitor cells, which would be an ideal cell source for cell therapy. Also notochordal cells (remnants of the embryonic notochord) have been recently pushed back into focus since these cells have regenerative potential and can activate disc cells. Growth factor treatment and molecular therapies could be less problematic. The biological solutions for NP and AF replacement are still more fiction than fact. However, tissue engineering just scratched the tip of the iceberg, more satisfying solutions are yet to be added to the biomedical pipeline.

"Fact versus Fiction – How paratextual information shapes our reading processes"

Our life is full of stories: some of them depict real-life events and were reported, e.g. in the daily news or in autobiographies, whereas other stories, as often presented to us in movies and novels, are fictional. However, we have only little insights in the neurocognitive processes underlying the reading of factual as compared to fictional contents. We investigated the neurocognitive effects of reading short narratives, labeled to be either factual or fictional. Reading in a factual mode engaged an activation pattern suggesting an action-based reconstruction of the events depicted in a story. This process seems to be past-oriented and leads to shorter reaction times at the behavioral level. In contrast, the brain activation patterns corresponding to reading fiction seem to reflect a constructive simulation of what might have happened. This is in line with studies on imagination of possible past or future events.

Science & Fiction: Imagination und Realität des Weltraums

Der Kosmos ist seit Menschengedenken ein Gegenstand der forschenden Neugierde und der phantastischen Projektion. Wissenschaft und Kunst, science and fiction, Realität und Fiktion, sind sich nie so nah wie angesichts des Weltraums, jenes unerreichbaren Ganzen. Astronom / innen und Weltraumingenieur/innen beschäftigen space artists, und umgekehrt schöpfen Schriftsteller/innen und Filmemacher/innen aus den Entdeckungen der Physik und Weltraumtechnik. Der Leitgedanke der diesem Band zugrunde liegenden Ringvorlesung Science & ­Fiction: Imagination und Realität des Weltraums war, die Weltraumexploration im weitesten Sinne kulturgeschichtlich zu verstehen, um alle Wissenschaften in das Thema einzubeziehen. Es wurden daher sowohl Naturwissenschaftler/innen als auch ebenso viele Geisteswissenschaftler/innen eingeladen. Sie beleuchten in ihren Beiträgen die Geschichte der wissenschaftlichen, technischen und künstlerischen Visualisierungen des Weltraums und stellen Ergebnisse und Projekte der Weltraumforschung vor. Ein besonderes Interesse liegt dabei auf den vielfältigen Beziehungen zwischen den Bereichen der fiction – der Visualisierungen und Imaginationen des Weltraums – und der science – der Realitäten der naturwissenschaftlichen Erforschung des Weltraums.
