ASP514 within the A1 domain of bovine von Willebrand factor is required for interaction with platelet glycoprotein Ib.

A mutant PAD-1 (D514-->Q) of the recombinant fragment PAD-1 comprising Leu469-Ser723 of the A1 domain of bovine von Willebrand factor (vWF) neither inhibited the binding of [125I]vWF to platelets nor the agglutination of human platelets induced by bovine vWF. PAD-1, on the other hand, inhibited human platelet agglutination induced by bovine vWF and [125I]vWF binding to human platelets. Collagen binding properties of the mutant, however, were indistinguishable from those of PAD-1. These results suggested that Asp514 within the A1 domain of vWF is required for interaction of bovine vWF with GPIb receptor on human platelets.

Ligand binding assays with recombinant proteins refolded on an affinity matrix.

This paper describes a procedure for performing ligand binding assays with recombinant proteins or protein fragments that can bind to an affinity matrix in the presence or absence of a denaturing agent but which require the presence of the denaturing agent to remain in solution. The method involves coupling of a known amount of the protein in a denaturing medium to a known amount of the affinity matrix, replacing the denaturing agent with a physiological buffer, and finally using the suspension of this protein-coupled matrix as the source of the recombinant protein to be studied for its functional properties. A constant volume of this suspension is incubated with different concentrations of a radiolabeled ligand. Radioactivity bound to the protein-coupled affinity matrix is determined after centrifugation and washing of the pellet. Nonspecific binding is determined either by using the uncoupled affinity matrix or by the standard technique of measuring the binding in the presence of excess unlabeled ligand.

An issue of access: delivering equitable health care for newly arrived refugee children in Australia.

Newly arrived refugees and asylum seekers are faced with many difficulties in accessing effective health care when settling in Australia. Cultural, language and financial constraints, lack of awareness of available services, and lack of health provider understanding of the complex health concerns of refugees can all contribute to limiting access to health care. Understanding the complexities of a new health care system under these circumstances and finding a regular health provider may be difficult. In some cases there may be a fundamental distrust of government services. The different levels of health entitlements by visa category and (for some) detention on arrival in Australia may further complicate the provision and use of health services for providers and patients. Children are particularly at risk of suboptimal health care due to the impact of these factors combined with the effect of resettlement stresses on parents' ability to care for their children. Unaccompanied and separated children, and those in detention experience additional challenges in accessing care. This article aims to increase awareness among health professionals caring for refugee children of the challenges faced by this group in accessing and receiving effective health care in Australia. Particular consideration is given to the issues of equity, rights of asylum seekers, communication and cultural sensitivities in health care provision, and addressing barriers to health care. The aim of the paper is to alert practitioners to the complex issues surrounding the delivery of health care to refugee children and provide realistic recommendations to guide practice.
