Arterial Or Venous: Where Are The Circulating Tumor Cells?, Elin S. Gray
Arterial Or Venous: Where Are The Circulating Tumor Cells?, Elin S. Gray
Research outputs 2014 to 2021
The study of circulating tumor cells (CTCs) has been largely confounded by the low number of these cells in the blood stream amid billions of other cells. To overcome this challenge numerous methodologies for CTC isolation have been described. Photoacoustic flow cytometry (Nedosekin et al., 2013), dielectrophoresis array (Maltoni et al., 2015) and microfluidics (Warkiani et al., 2015) are among the most sophisticated of these methodologies. However, methods based on immunecapture and immunestaining are still the more frequently utilized, with CellSearch® remaining the most commonly used method to date and the only US FDA approved (Alix-Panabieres and Pantel, 2014). Irrespective …
Accurate Modelling And Positioning Of A Magnetically-Controlled Catheter Tip, Vi T. H. Le
Accurate Modelling And Positioning Of A Magnetically-Controlled Catheter Tip, Vi T. H. Le
Theses: Doctorates and Masters
This thesis represents the initial phase of a proposed operator and patient friendly method designed to semi-automate the positioning and directing of an intravascular catheter in the human heart using a variable electromagnetically induced field to control a catheter tip equipped with three tiny fixed magnets oriented in XYZ planes. Here we demonstrate a comprehensive mathematical model which accurately calculates the magnetic field generated by the electromagnet system, and the magnetic torques and forces exerted on a three-magnet tip catheter. From this we have developed an iterative predictive computer algorithm to show the displacement and deflection of the catheter tip. …

Objective: Glycans attached to the Fc portion of IgG are important modulators of IgG effector functions. Interindividual differences in IgG glycome composition are large and they associate strongly with different inflammatory and autoimmune diseases. IKZF1, HLA–DQ2A/B, and BACH2 genetic loci that affect IgG glycome composition show pleiotropy with systemic lupus erythematosus (SLE), indicating a potentially causative role of aberrant IgG glycosylation in SLE. We undertook this large multicenter case–control study to determine whether SLE is associated with altered IgG glycosylation. Methods: Using ultra-performance liquid chromatography analysis of released glycans, we analyzed the composition of the IgG glycome in 261 SLE …

The lack of readily available biomarkers is a significant hindrance toward progressing to effective therapeutic and preventative strategies for Alzheimer's disease (AD). Blood-based biomarkers have potential to overcome access and cost barriers and greatly facilitate advanced neuroimaging and cerebrospinal fluid biomarker approaches. Despite the fact that preanalytical processing is the largest source of variability in laboratory testing, there are no currently available standardized preanalytical guidelines. The current international working group provides the initial starting point for such guidelines for standardized operating procedures (SOPs). It is anticipated that these guidelines will be updated as additional research findings become available. The statement …

Defining Young In The Context Of Prostate Cancer, Suzanne Chambers, Anthony Lowe, Melissa Hyde, Leah Zajdlewicz, Robert F. Gardiner, David Sandoe, Jeff Dunn
Research outputs 2014 to 2021
The experience of prostate cancer is for most men a major life stress with the psychological burden of this disease falling more heavily on those who are younger. Despite this, being young as it applies to prostate cancer is not yet clearly defined with varied chronological approaches applied. However, men’s responses to health crises are closely bound to life course and masculinities from which social roles emerge. This paper applied qualitative methodology (structured focus groups and semistructured interviews with expert informants) using interpretative phenomenological analysis to define what it means to be young and have prostate cancer. Structured focus groups …

Musculoskeletal examinations provide informative and valuable quantitative insight into muscle and bone health. DXA is one mainstream tool used to accurately and reliably determine body composition components and bone mass characteristics in-vivo. Presently, whole body scan models separate the body into axial and appendicular regions, however there is a need for localised appendicular segmentation models to further examine regions of interest within the upper and lower extremities. Similarly, in-consistencies pertaining to patient positioning exist in the litera-ture which influence measurement precision and analysis out-comes highlighting a need for standardised procedure. This paper provides standardised and reproducible: 1) positioning and analysis …
The N-Glycosylation Of Immunoglobulin G As A Novel Biomarker Of Parkinson’S Disease, Alyce Christine Russell
The N-Glycosylation Of Immunoglobulin G As A Novel Biomarker Of Parkinson’S Disease, Alyce Christine Russell
Theses: Doctorates and Masters
For neurodegenerative diseases, interventions during the early stages of the disease, before significant neurodegeneration has occurred, are associated with an increased probability of slowing or halting the disease process. In order to intervene early, it is essential that an accurate diagnosis is obtained and that disease progression can be monitored. This is particularly relevant for Parkinson’s disease (PD; International Classification of Diseases version 10) because significant neurodegeneration has already occurred by the time the clinical motor symptoms are present. Therefore, the development of translatable, high-throughput biomarkers for large scale population screening is a crucial area of research. Of promise are …

Cell-based strategies represent a new frontier in the treatment of immune-mediated disorders. However, the paucity of markers for isolation of molecularly defined immunomodulatory cell populations poses a barrier to this field. Here, we show that ATP-binding cassette member B5 (ABCB5) identifies dermal immunoregulatory cells (DIRCs) capable of exerting therapeutic immunoregulatory functions through engagement of programmed cell death 1 (PD-1). Purified Abcb5+ DIRCs suppressed T cell proliferation, evaded immune rejection, homed to recipient immune tissues, and induced Tregs in vivo. In fully major-histocompatibility-complex-mismatched cardiac allotransplantation models, allogeneic DIRCs significantly prolonged allograft survival. Blockade of DIRC-expressed PD-1 reversed the inhibitory effects of …
The Feasibility Of Implementing A Novel Electrical Stimulation Device In The Self-Management Of Hand Burn Pain, Katrina Liddiard
The Feasibility Of Implementing A Novel Electrical Stimulation Device In The Self-Management Of Hand Burn Pain, Katrina Liddiard
Theses : Honours
Burns are widely acknowledged as one of the most painful injuries experienced, and poorly controlled pain following burn injury has been linked to reduced psychological adjustment, lower quality of life, and increased risk of developing a chronic pain state. Transcutaneous electrical nerve stimulation has been used for pain relief in a range of medical conditions, and may have the potential to reduce pain and analgesic consumption for burns patients. The burn care environment presents unique challenges to the introduction of new interventions, and the feasibility of introducing a novel form of electrical stimulation into this environment has not been tested. …

Evaluation Of A Modified Food Frequency Questionnaire To Measure Lignans In Australian Men And Women, Ying Qi Winnie Li
Theses: Doctorates and Masters
Phytoestrogens are plant compounds that possess estrogenic and biological properties that have been postulated to protect against chronic diseases. Isoflavonoids and lignans are two main classes of phytoestrogen that have been investigated for their estrogenic efficacy and occurrence in the human diet. Isoflavonoids are found in soy and related products, whereas lignans are found in a wider range of plant-based foods, such as cereals, vegetables, fruits, legumes, nuts and seeds; and in beverages such as tea, coffee and wine. In Western populations with low dietary intake of soy products, compared to the Asian counterparts, lignans could be a more important …
