**Background:** Diffusion Tensor Imaging (DTI) is a popular technique used to study collagen fibre architecture in articular cartilage. Interpretation of DTI images, however, is limited to the predominant alignment of fibres only[1]. Dispersion of fibre orientations can be measured using Small angle X-ray scattering (SAXS). Here, we present a comparison of SAXS and DTI measurements in cartilage. W ... More

Microbeam radiation therapy (MRT), using X-rays from a synchrotron, is a novel, preclinical form of radiotherapy that shows promise of providing a major advance in cancer control if successfully translated to clinical practice (Brauer-Krisch et al, 2010; Crosbie et al, 2010). Clinical translation of MRT requires developing a protocol for a patient positioning system (PPS). Following recent develop ... More

Acid soils comprise ca. 4 billion ha of the global ice-free land or ca. 40 % of the world’s arable land. In these acid soils, the elevated solubility of Al-containing minerals results in increased concentrations of Al in the soil solution. Soluble Al is highly toxic to root growth, reducing elongation of roots in as little as 5 min due to an inhibition of wall loosening as required for cell elon ... More

Microbeam Radiation Therapy (MRT) is a promising preclinical radiotherapy modality that uses micron-sized, spatially fractionated radiation fields to treat radioresistant and otherwise untreatable tumours. A typical MRT configuration consists of arrays of 25-75 µm wide high-dose 'peaks' separated by 100-400 µm wide low-dose 'valleys' that are produced by an x-ray spectrum from a synchrotron ligh ...

Ovine leather has around half the strength of bovine leather and is therefore not suitable for high value applications such as shoes. For leather from a variety of animals it has been found that the extent of collagen fibril alignment (orientation index) is closely correlated with the strength of the leather. We tested whether biaxial stretching for the duration of tanning or compressing pickled p ... More
