As curative treatments for the common knee problems are not available to date, knee pathologies typically progress and often lead to osteoarthritis (OA). While the roles that the meniscus plays in knee biomechanics are well characterized, biological mechanisms underlying meniscus pathophysiology and roles in knee pain and OA progression are not fully clear. Experimental treatments for knee disorders that are successful in animal models often produce unsatisfactory results in humans due to species differences or the inability to fully replicate disease progression in experimental animals. The use of animals with spontaneous knee pathologies, such as dogs, can significantly help addressing this issue. As microscopic and macroscopic anatomy of the canine and human menisci are similar, spontaneous meniscal pathologies in canine patients are thought to be highly relevant for translational medicine. However, it is not clear whether the biomolecular mechanisms of pain, degradation of extracellular matrix, and inflammatory responses are species dependent. The aims of this review are (1) to provide an overview of the anatomy, physiology, and pathology of the human and canine meniscus, (2) to compare the known signaling pathways involved in spontaneous meniscus pathology between both species, and (3) to assess the relevance of dogs with spontaneous meniscal pathology as a translational model. Understanding these mechanisms in human and canine meniscus can help to advance diagnostic and therapeutic strategies for painful knee disorders and improve clinical decision making.}, language = {en} } @article{WallnyBrackmannGuniaetal.2006, author = {Wallny, Thomas A. and Brackmann, H.

The treatment of haemophilic arthropathies can require strong painkillers with severe side-effects. Therefore, a special yet simple acupuncture technique was evaluated in the treatment of these joint problems. Twelve patients with a factor VIII activity < 1\% and at least one painful arthropathy in both lower extremities were included in this single-blinded study. The non-treated side served as a control. Treatment was assessed by a visual analogue scale (VAS) and an orthopaedic clinical examination. Only one needle was inserted at the rear fontanelle once per week and in 15 cycles. Ten of 12 patients showed an improvement of their pain perception. The average VAS could be reduced from 6.8 to 5.0. The side not receiving treatment showed a reduction from 4.1 to 4.0. No side-effects were observed. Even though interpretation of our data are limited due to the small patient numbers, significant improvement of the VAS after treatment suggests that acupuncture has a measurable positive effect in pain management for haemophilic arthropathy of the lower extremities.}, language = {en} } @article{BogenBenderLoeweetal.2015, author = {Bogen, Oliver and Bender, Olaf and Loewe, Jana and Blenau, Wolfgang and Thevis, Beatrice and Schroeder, Wolfgang and Margolis, Richard U. and Levine, Jon D. and Hucho, Ferdinand}, title = {Neuronally produced versican V2 renders C-fiber nociceptors IB4-positive}, series = {Journal of neurochemistry}, volume = {134}, journal = {Journal of neurochemistry}, number = {1}, publisher = {Wiley-Blackwell}, address = {Hoboken}, issn = {0022-3042}, doi = {10.1111/jnc.13113}, pages = {147 -- 155}, year = {2015}, abstract = {A subpopulation of nociceptors, the glial cell line-derived neurotrophic factor (GDNF)-dependent, non-peptidergic C-fibers, expresses a cell-surface glycoconjugate that can be selectively labeled with isolectin B4 (IB4), a homotetrameric plant lectin from Griffonia simplicifolia. We show that versican is an IB4-binding molecule in rat dorsal root ganglion neurons. Using reverse transcriptase polymerase chain reaction (RT-PCR), insitu hybridization and immunofluorescence experiments on rat lumbar dorsal root ganglion, we provide the first demonstration that versican is produced by neurons. In addition, by probing Western blots with splice variant-specific antibodies we show that the IB4-binding versican contains only the glycosaminoglycan alpha domain. Our data support V2 as the versican isoform that renders this subpopulation of nociceptors IB4-positive (+). A subset of nociceptors, the GDNF-dependent non-peptidergic C-fibers can be characterized by its reactivity for isolectin B4 (IB4), a plant lectin from Griffonia simplicifolia. We have previously demonstrated that versican V2 binds IB4 in a Ca2+-dependent manner. However, given that versican is thought to be the product of glial cells, it was questionable whether versican V2 can be accountable for the IB4-reactivity of this subset of nociceptors. The results presented here prove - for the first time - a neuronal origin of versican and suggest that versican V2 is the molecule that renders GDNF-dependent non-peptidergic C-fibers IB4-positive.}, language = {en} } @article{Dornhof2011, author = {Dornhof, Sarah}, title = {Regimes of visibility representing violence against women in the French banlieue}, series = {Feminist review}, journal = {Feminist review}, number = {98}, publisher = {Palgrave Macmillan}, address = {Basingstoke}, issn = {0141-7789}, doi = {10.1057/fr.2011.2}, pages = {110 -- 127}, year = {2011}, abstract = {Recent discussions about violence against women have shifted their attention to specific forms of violence in relation to migration and Islam. In this article, I consider different modes of representing women's experiences in French immigrant communities. These representations relate to the French feminist movement Ni Putes Ni Soumises (neither whore nor submissive), a movement that in the early 2000s deplored both the sustained degradation of certain banlieue neighborhoods and also the charges and restrictions that this entails, particularly for young women. Drawing on different narratives and images of women's painful experience, I consider, in a first step, how the question of representing violence against (post) migrant women is framed in terms of the tension between universality and particularity within French republicanism. In the next part of my argument, I bring into focus the question of how to access women's suffering. For a perspective on pain not as an interiorized, private experience but as an accessible complex of practices, articulations, memories, visions and social reconfigurations, I consider Smain Laacher's sociological study (2008) about written testimonies of violent experience that had been addressed by (post) migrant women to French women organizations such as Ni Putes Ni Soumises. I finally suggest reading women's accounts on violence not in relation to a universal discourse of rights, but as a political contestation of the naturalized order of representing violence, suffering and agency inside French banlieue communities. Drawing on Jacques Ranciere's notion of dissensus, such a contestation can be staged through words by those who have no visibility in the representational order, words not to criticize the unaccomplished ideals of universal equality, but to create a universal community and a common language of experience in the mode of 'as-if'.}, language = {en} } @misc{KraheSpringerWeinmanetal.2013, author = {Krahe, Charlotte and Springer, Anne and Weinman, John A. and Fotopoulou, Aikaterini}, title = {The social modulation of pain - others as predictive signals of salience ; a systematic review}, series = {Frontiers in human neuroscienc}, volume = {7}, journal = {Frontiers in human neuroscienc}, number = {29}, publisher = {Frontiers Research Foundation}, address = {Lausanne}, issn = {1662-5161}, doi = {10.3389/fnhum.2013.00386}, pages = {21}, year = {2013}, abstract = {Several studies in cognitive neuroscience have investigated the cognitive and affective modulation of pain. By contrast, fewer studies have focused on the social modulation of pain, despite a plethora of relevant clinical findings. Here we present the first review of experimental studies addressing how interpersonal factors, such as the presence, behavior, and spatial proximity of an observer, modulate pain. Based on a systematic literature search, we identified 26 studies on experimentally induced pain that manipulated different interpersonal variables and measured behavioral, physiological, and neural pain-related responses. We observed that the modulation of pain by interpersonal factors depended on (1) the degree to which the social partners were active or were perceived by the participants to possess possibility for action; (2) the degree to which participants could perceive the specific intentions of the social partners; (3) the type of pre-existing relationship between the social partner and the person in pain, and lastly, (4) individual differences in relating to others and coping styles. Based on these findings, we propose that the modulation of pain by social factors can be fruitfully understood in relation to a recent predictive coding model, the free energy framework, particularly as applied to interoception and social cognition. Specifically, we argue that interpersonal interactions during pain may function as social, predictive signals of contextual threat or safety and as such influence the salience of noxious stimuli. The perception of such interpersonal interactions may in turn depend on (a) prior beliefs about interpersonal relating and (b) the certainty or precision by which an interpersonal interaction may predict environmental threat or safety.}, language = {en} }
