    • An approach is presented that allows multi-scale characterisations of heterogeneous deformation in crystalline materials by employing a range of characterisation techniques including: electron backscatter diffraction, digital image correlation and neutron diffraction powder measurements. The approach will be used to obtain critical information about the variations in parameters that characterise the deformed state in different crystallographic orientation texture components of a sample in a statistically significant way. These parameters include lattice strains, texture evolution, peak broadening, dislocation density, planar faults, phase changes and surface strain. This approach allows verification of models of plastic deformation to provide a more detailed view of plastic deformation heterogeneity at multiple length scales than obtained by other characterisation approaches. The approach demonstrated here is applied to two stainless steel alloys; an alloy that exhibits phase transformation during deformation and an alloy that remains the same phase all through deformation process.

  • Plasma cytokine profiles in elderly humans

    • It is known that as we age, immune dysregulation often occurs, leading to failing health, and increased susceptibility to a number of different diseases. In this study we have investigated plasma cytokine profiles in order to identify immune markers of ageing. Plasma samples were obtained from 138 participants of the Swedish longitudinal NONA study (aged 86, 90 and 94 years) and 18 healthy Swedish volunteers (aged between 32 and 59 years). Our results show significantly increased levels of the pro-inflammatory cytokine interleukin-6 (P<0.0001) and soluble intercellular adhesion molecule-1 (P<0.0001) in the elderly group. The anti-inflammatory cytokine interleukin-10 did not alter with age whereas active (naturally processed) transforming growth factor-ß levels were significantly (P<0.0001) increased in the elderly group. No difference was observed between males and females. These data suggest that there are measurable changes in cytokine profiles with ageing with increased levels of potentially harmful molecules, which may contribute to immune alterations and declining health in the elderly population. © 2003 Elsevier Science Ireland Ltd.
