The A1 pulley was released distally in consecutive stages by 25%, 50%, 75% and 100% of its length. The force required to fully flex the digit at each stage was recorded. The force decreased with more extensive A1 pulley release and this became significant when more than 50% of the pulley was released. These changes were probably due to loss of friction(More)
BACKGROUND Current gene- and cell-based therapies have significant limitations which impede widespread clinical application. Taking diabetes mellitus as a paradigm, we have sought to overcome these limitations by ex vivo electrotransfer of a nonviral insulin expression vector into primary hepatocytes followed by immediate autologous reimplantation in a(More)
The aim of this study was to establish the long-term biomechanical and histological properties of 2-octylcyanoacrylate-assisted microvascular anastomosis over conventional suture-only anastomosis in the laboratory rat model. The biomechanical and histological properties of three groups of vessels were compared: 1) vessels with 2-octylcyanoacrylate-assisted(More)
PURPOSE 32P BioSilicon is a new, implantable, radiological medical device that comprises particles of highly pure silicon encapsulating 32phosphorus (32P) for the treatment of unresectable solid tumors. Prior to administration, the device particles are suspended in a formulant which provides an even suspension of the intended dose for implantation. The(More)
Thermoresponsive polymer-coated magnetic nanoparticles loaded with anti-cancer drugs are of considerable interest for novel multi-modal cancer therapies. Such nanoparticles can be used for magnetic drug targeting followed by simultaneous hyperthermia and drug release. Gamma-Fe(2)O(3) iron oxide magnetic nanoparticles (MNP) with average sizes of 14, 19 and(More)
Purpose: P BioSilicon is a new, implantable, radiological medical device that comprises particles of highlypure siliconencapsulating phosphorus (P) for the treatmentofunresectable solid tumors. Prior to administration, the device particles are suspended in a formulant which provides an even suspension of the intended dose for implantation.The primary(More)
Infraclavicular subclavian venepuncture in the oedematous burned patient is often difficult because of increased depth of the vein. In addition, proper patient positioning is not easily achieved because of extensive burns, generalised oedema and bulky dressings. To overcome these difficulties, a modified technique of infraclavicular subclavian venepuncture(More)
Conquering the AIDS epidemic remains one of the most challenging global health issues. Despite impressive advances in combination antiretroviral therapy (cART) to treat HIV, and substantial progress in the development of prevention interventions, a protective vaccine has remained elusive. Successful vaccination will require the immune system to function(More)
This study investigates the effect of storage at -150°C in the vapour phase of liquid nitrogen on the torsion properties of whole intact femurs to be used as allografts. Twenty-five adult dog femurs, stripped of all soft tissue, were used. It has been established that storage at -70°C does not significantly affect the torsion properties of bone. In this(More)
