Degradable polyester scaffolds with controlled surface chemistry combining minimal protein adsorption with specific bioactivation

Abstract: Advanced biomaterials and scaffolds for tissue engineering place high demands on materials and exceed the passive biocompatibility requirements previously considered acceptable for biomedical implants. Together with degradability, the activation of specific cell–material interactions and a three-dimensional environment that mimics the extracellular matrix are core challenges and prerequisites for the organization of living cells to functional tissue. Moreover, although bioactive signalling combined with minimization of non-specific protein adsorption is an advanced modification technique for flat surfaces, it is usually not accomplished for three-dimensional fibrous scaffolds used in tissue engineering. Here, we present a one-step preparation of fully synthetic, bioactive and degradable extracellular matrix-mimetic scaffolds by electrospinning, using poly(D,L-lactide-co-glycolide) as the matrix polymer. Addition of a functional, amphiphilic macromolecule based on star-shaped poly(ethylene oxide) transforms current biomedically used degradable polyesters into hydrophilic fibres, which causes the suppression of non-specific protein adsorption on the fibres’ surface. The subsequent covalent attachment of cell-adhesion-mediating peptides to the hydrophilic fibres promotes specific bioactivation and enables adhesion of cells through exclusive recognition of the immobilized binding motifs. This approach permits synthetic materials to directly control cell behaviour, for example, resembling the binding of cells to fibronectin immobilized on collagen fibres in the extracellular matrix of connective tissue.

Lyons, Terry and Skitmore, Martin (2004) Project risk management in the Queensland engineering construction industry: a survey. International Journal of Project Management 22(1):pp. 51-61. Copyright 2004 Elsevier PROJECT RISK MANAGEMENT IN THE QUEENSLAND ENGINEERING CONSTRUCTION INDUSTRY: A SURVEY

Abstract: This paper provides the results of a survey of senior management involved in the Queensland engineering construction industry, concerning the usage of risk management techniques. These are described in comparison with four earlier surveys conducted around the world and indicate that: the use of risk management is moderate to high, with very little differences between the types, sizes and risk tolerance of the organisations, and experience and risk tolerance of the individual respondents; risk management usage in the execution and planning stages of the project life cycle is higher than in the conceptual or termination phases; risk identification and risk assessment are the most often used risk management elements ahead of risk response and risk documentation; brainstorming is the most common risk identification technique used; qualitative methods of risk assessment are used most frequently; risk reduction is the most frequently used risk response method, with the use of contingencies and contractual transfer preferred over insurance; and project teams are the most frequent group used for risk analysis, ahead of in-house specialists and consultants.

Difficulties and coping strategies of Sudanese refugees: a qualitative approach.

Abstract: A qualitative approach was used to interview 23 Sudanese refugees residing in Brisbane, Australia. Semi-structured interviews were conducted to examine the participants' pre-migration, transit and post-migration experiences. Refugees reported traumatic and life-threatening experiences during the pre-migration and transit phases, and difficulties with resettlement during the post-migration phase. Nevertheless, participants reported using a number of coping strategies across all phases, including: reliance on religious beliefs, cognitive strategies such as reframing the situation, relying on their inner resources, and focusing on future wishes and aspirations. Social support also emerged as a salient coping strategy. The findings are useful for mental health professionals as they highlight the difficulties experienced by refugees across phases of migration as well as strategies they use to manage these traumas and stresses.
