    Bangladesh was born in a violent struggle many label genocide. Few were ever prosecuted. The article considers the issue in terms of competing narratives and the issue of ownership of ‘truth’ and the contribution of images of 1971 to the constitution of Bangladesh. Since 2010 belated war crimes trials have been help for local collaborators; the accused mainly come from Islamic political parties and the verdicts have spurred popular protests resulting in violent confrontations. The trials have been criticised as political trials aimed at eliminating political opposition rather than achieving justice and healing historical wounds. Is this a defining moment for Bangladesh that can change the form of politics – one that breaks the hold of the state over the narrative and ushers in a new form of collaborative enterprise - or is this the occasion for a resurgence of religious sentiments that weakens the secular constitution and increases social instability? Bangladesh nació en una violenta lucha que muchos califican de genocidio. Pocos fueron juzgados. Su legado continúa. Este artículo considera el asunto en términos de su contribución a la imaginería de la constitución de Bangladesh y el impacto que tienen las imágenes de la lucha. Desde 2010, los tardíos juicios por crímenes de guerra han estado apoyados por colaboracionistas nacionales; los acusados provienen principalmente de los partidos políticos islámicos y los veredictos han resultado en protestas populares que causaron violentas confrontaciones. Los juicios han sido criticados por ser juicios políticos, que apuntan a eliminar la oposición política en lugar de conseguir justicia y sanar las heridas históricas. ¿Es este un momento definitivo para que Bangladesh pueda cambiar la forma de la política –una que rompa el control del Estado sobre la narrativa y los encargados del orden, por una forma nueva de empresa colaboracionista– o es ésta la ocasión para el resurgimiento de sentimientos religiosos que debiliten la Constitución secular e incrementen la inestabilidad social?

    BIOMECHANICAL ASSESSMENT OF CHANGE OF DIRECTION PERFORMANCE IN MALE UNIVERSITY SOCCER PLAYERS

    The purpose of this study was to identify biomechanical variables that distinguish change of direction performance in an athletic population. Twenty varsity men’s soccer athletes were recruited. Motion capture and force plate data were collected simultaneously during the plant phase of a 505 agility test. The median time to complete the agility task was used to distinguish a “fast” group (n=10) and a “slow” group (n=10). An ANOVA (0.05 alpha level = was used to compare groups‘ kinematic and kinetic variables. Several differences were found between groups including: contact time, transition, relative horizontal to vertical ground reaction force, center of mass height, torso lean, pelvis rotation, spine rotation, hip adduction/abduction. The findings suggest that fast and slow change of direction performance adopt different technical strategies

    The role of mast cells and fibre type in ischaemia reperfusion injury of murine skeletal muscles

    BACKGROUND: Ischaemia reperfusion (IR) injury of skeletal muscle, is a significant cause of morbidity following trauma and surgical procedures, in which muscle fibre types exhibit different susceptibilities. The relative degree of mast cell mediated injury, within different muscle types, is not known. METHODS: In this study we compared susceptibility of the fast-twitch, extensor digitorum longus (EDL), mixed fast/slow-twitch gastrocnemius and the predominately slow-twitch soleus, muscles to ischemia reperfusion (IR) injury in four groups of mice that harbour different mast cell densities; C57/DBA mast cell depleted (W(f)/W(f)), their heterozygous (W(f)/+) and normal littermates (+/+) and control C57BL/6 mice. We determined whether susceptibility to IR injury is associated with mast cell content and/or fibre type and/or mouse strain. In experimental groups, the hind limbs of mice were subjected to 70 minutes warm tourniquet ischemia, followed by 24 h reperfusion, and the muscle viability was assessed on fresh whole-mount slices by the nitroblue tetrazolium (NBT) histochemical assay. RESULTS: Viability was remarkably higher in the W(f)/W(f )strain irrespective of muscle type. With respect to muscle type, the predominately slow-twitch soleus muscle was significantly more resistant to IR injury than gastrocnemius and the EDL muscles in all groups. Mast cell density was inversely correlated to muscle viability in all types of muscle. CONCLUSION: These results show that in skeletal muscle, IR injury is dependent upon both the presence of mast cells and on fibre type and suggest that a combination of preventative therapies may need to be implemented to optimally protect muscles from IR injury
