BACKGROUND Decision aids are often used to assist individuals confronted with a diagnosis of a serious illness to make decisions about treatment options. However, they are rarely utilised to help those with chronic or age related conditions to make decisions about care services. Decision aids should also be useful for carers of people with decreased(More)
Recent studies suggest the importance of the transition of airway epithelial cells (EMT) in pulmonary fibrosis, and also indicate a role for Wingless protein (Wnt)/β-catenin signaling in idiopathic pulmonary fibrosis. We investigated the possible role of the Wnt signaling pathway in inducing EMT in lung epithelial cells, and sought to unravel the role of(More)
To gain an understanding of the factors that affect the risks and the adoption of risk control measures during the care of bariatric patients, focus groups were conducted in rural and metropolitan locations in Australia. It was found that the manual handling injury risk to carers is influenced by the design of the environments within which patient movement(More)
Textured surfaces with periodic topographical features and long-range order are highly attractive for directing cell-material interactions. They mimic physiological environments more accurately than planar surfaces and can fundamentally alter cell alignment, shape, gene expression, and cellular assembly into superstructures or microtissues. Here we(More)
Carers of bariatric (morbidly obese) clients are exposed to manual handling injury risk throughout the journey that such clients take within the healthcare system. To identify the factors that affect risks associated with bariatric clients and the subsequent adoption of risk control measures focus groups were conducted in two Australian state capitals: a(More)
Cancer cell invasion through the extracellular matrix is associated with metastatic spread and therapeutic resistance. In carcinomas, the detachment and dissemination of individual cells has been associated with an epithelial-mesenchymal transition, but tumors can also invade using collective, multicellular phenotypes. This malignant tumor progression is(More)
Collective behaviors emerge from coordinated cell-cell interactions during the morphogenesis of tissues and tumors. For instance, cells may display density-dependent phase transitions from a fluid-like "unjammed" phase to a solid-like "jammed" phase, while different cell types can "self-sort". Here, we comprehensively track single cell dynamics in mixtures(More)
3D printed biomaterials with spatial and temporal functionality could enable interfacial manipulation of fluid flows and motile cells. However, such dynamic biomaterials are challenging to implement since they must be responsive to multiple, biocompatible stimuli. Here, we show stereolithographic printing of hydrogels using noncovalent (ionic) crosslinking,(More)
Circulating tumour cells (CTCs) disseminating through the bloodstream represent a missing link between the initiating tumour and its metastatic colonies1. The isolation and analysis of CTCs from patient blood samples could enable noninvasive ‘liquid biopsies’ for the early detection, diagnosis and prognosis of cancer2. However, CTCs are highly heterogeneous(More)
