Die hier versammelten Beiträge spiegeln den aktuellen Stand der Debatte um Intersektionalität 20 Jahre nach Prägung des Begriffes im Schwarzen Feminismus in den USA. Bei seiner transatlantischen Reise durchlief der Ansatz Metamorphosen und fiel in Europa auf vorbereiteten Boden, insbesondere in anglophonen und deutschsprachigen feministischen Diskursen. Klasse, Geschlecht, Ethnizität und "Rasse", Sexualität, Behinderung, Alter und andere Dimensionen von Ungleichheit und Identität werden inzwischen in intersektioneller Perspektive untersucht. In diesem Band wird der Ansatz vorgestellt und in transdisziplinären und transnationalen Analyseperspektiven wie Diskurstheorie, Biographieforschung, Wissenssoziologie, Rahmenanalyse und Sozialstrukturanalyse verortet; auch werden kritische Interventionen zu Problemen und Grenzen dieses Konzepts diskutiert.

Originally conceived by Kimberlé Crenshaw in 1989 as a tool for the analysis of the ways in which different forms of social inequality, oppression and discrimination interact and overlap in multidimensional ways, the concept of 'intersectionality' has attracted much attention in international feminist debates over the last decade. Framing Intersectionality brings together proponents and critics of the concept, to discuss the 'state of the art' with those that have been influential in the debates that surround it. Exploring issues such as migration, identity, media coverage of sexual violence a.

This study aimed to complete the scientific basis for the validation of a coffee silverskin extract (CSE) as a novel food ingredient according to European legislation. Nutritional value, safety, effects on biochemical biomarkers and excretion of short chain fatty acids (SCFAs) in vivo of CSE were assessed. Proteins, amino acids, fat, fatty acids, fiber, simple sugars and micronutrients were analyzed. For the first time, toxicological and physiological effects were evaluated in vivo by a repeated-dose study in healthy Wistar rats. Hormone secretion, antioxidant (enzymatic and no-enzymatic) and anti-inflammatory biomarkers, and dietary fiber fermentability of CSE (analysis of SCFAs in feces) were studied in biological samples. This unique research confirms the feasibility of CSE as a human dietary supplement with several nutrition claims: &ldquo ; source of proteins (16%), potassium, magnesium, calcium and vitamin C, low in fat (0.44%) and high in fiber (22%)&rdquo ; . This is the first report demonstrating that its oral administration (1 g/kg) for 28 days is innocuous. Hormone secretion, antioxidant or anti-inflammatory biomarkers were not affected in heathy animals. Total SCFAs derived from CSE fiber fermentation were significantly higher (p < ; 0.05) in male treated rats compared to male control rats. All the new information pinpoints CSE as a natural, sustainable and safe food ingredient containing fermentable fiber able to produce SCFAs with beneficial effects on gut microbiota.

10 páginas, 8 figuras. ; Eph receptors and their ligands, the ephrins, have been implicated in early patterning and axon guidance in vertebrate embryos. Members of these families play pivotal roles in the formation of topographic maps in the central nervous system, the formation of brain commissures, and in the guidance of neural crest cells and motor axons through the anterior half of the somites. Here, we report a highly dynamic expression pattern of the chick EphA7 gene in the developing limb. Expression is detected in discrete domains of the dorsal mesenchyme from 3 days of incubation. The expressing cells are adjacent to the routes where axons grow to innervate the limb at several key points: the region of plexus formation, the bifurcation between dorsal and ventral fascicles, and the pathway followed by axons innervating the dorsal muscle mass. These results suggested a role for EphA7 in cell-cell contact-mediated signalling in dorsal limb patterning and/or axon guidance. We carried out experimental manipulations in the chick embryo wing bud to alter the dorsoventral patterning of the limb. The analyses of EphA7 expression and innervation in the operated wings indicate that a signal emanating from the dorsal ectoderm regulates EphA7 in such a way that, in its absence, the wing bud lacks EphA7 expression and shows innervation defects at the regions where the gene was downregulated. EphA7 downregulation in the dorsal mesenchyme after dorsal ectoderm removal is more rapid than that of Lmx-1, the gene known to mediate dorsalisation in response to the ectodermal signal. These results add a new gene to the dorsalisation signalling pathway in the limb. Moreover, they implicate the Eph receptor family in the patterning and innervation of the developing limb, extending its role in axon pathfinding to the distal periphery. ; This work was supported by grants from the Spanish Ministry of Education and Culture (DGICYT-PM95-0024) and the European Union Biotech Programme (BIO4-CT96-0659) to M.
