Radionuclide solubility is one of the factors that can determine the 'source term' for potential migration to the far field. Hence, the mechanisms of immobilisation of radionuclides in cements need close study in order to quantify the nature of the binding. The nature of the binding forces in a cement matrix is very species sensitive, so it is difficult to produce a general description. This re...

The anatomy of the ankle, and the types of sporting injuries that occur in this joint, are described. Traditional treatment of soft tissue injuries involves immobilisation, and the value of this is questioned. An alternative treatment strategy is described, and involves immobilisation and compression for twenty-four hours, followed by rapid mobilisation using a balance board. This alternative s...

In this study three forms of treatment for ruptures of the lateral ligament of the ankle have been compared with reference to their effect upon the final mechanical stability of the ankle, the duration of morbidity immediately after injury, and the incidence of complaints one year after injury. The three forms of treatment used were mobilisation, immobilisation for six weeks, and suture of the ...

BACKGROUND Ankle fractures are common. Management of ankle fractures generally involves a period of immobilisation followed by rehabilitation to reduce pain, stiffness, weakness and swelling. The effects of a rehabilitation program are still unclear. However, it has been shown that important components of rehabilitation programs may not confer additional benefits over exercise alone. The primar...

Different methods of preparing lipases for use in organic media are critically reviewed. Solid lipase preparations can be made by typical immobilisation methods such as adsorption, entrapment, covalent coupling or cross-linking. Immobilisation is especially attractive for lipases because, in addition to the normal benefits of enzyme immobilisation, it can also lead to a considerable increase in...

Despite widespread use of radiofrequency (RF) shrinkage, there have been no animal studies on the effects of post-operative immobilisation on the histological properties of the shrunken tissue. We have therefore examined the role of post-operative immobilisation after RF shrinkage with special emphasis on the histological properties of collagenous tissue. One patellar tendon of 66 New Zealand W...

The high sensitivity and specificity of DNA hybridisation techniques makes them powerful tools for environmental or clinical analysis. This work describes the development of a DNA piezoelectric biosensor for the detection of the hybridisation reaction. Attention was focused on the choice of the coating chemistry that could be used for the immobilisation of oligonucleotides onto the gold surface...

Patellar dislocations are a common injury in the emergency department. The conservative management consists of immobilisation with a cylinder cast, posterior splint or removable knee brace. No consensus seems to exist on the most appropriate means of conservative treatment or the duration of immobilisation. Therefore the aims of this review were first to examine whether immobilisation with a cy...

Poly(methyl methacrylate) (PMMA) microfluidic devices have become promising platforms for a wide range of applications. Here we report a simple method for immobilising histidine-tagged enzymes suitable for PMMA microfluidic devices. The 1-step-immobilisation described is based on the affinity of the His-tag/Ni-NTA interaction and does not require prior amination of the PMMA surface, unlike many...

This thesis describes immobilisation techniques for biomolecules on solid surfaces via an intermediate self-assembled or Langmuir-Blodgett (LB) film. Such films are advantageous, because the biological activity can be optimised by tailoring the layer composition. Factors like charge density, density of the linking group and composition of the monolayer matrix have particularly large effects on ...
