Heat-Mediated Reduction Of Apoptosis In Uvb-Damaged Keratinocytes In Vitro And In Human Skin Ex Vivo, Leslie Calapre, Elin S. Gray, Sandrine Kurdykowski, Anthony David, Prue Hart, Pascal Descargues, Mel R. Ziman

Research outputs 2014 to 2021

Background:

UV radiation induces significant DNA damage in keratinocytes and is a known risk factor for skin carcinogenesis. However, it has been reported previously that repeated and simultaneous exposure to UV and heat stress increases the rate of cutaneous tumour formation in mice. Since constant exposure to high temperatures and UV are often experienced in the environment, the effects of exposure to UV and heat needs to be clearly addressed in human epidermal cells.

Methods:

In this study, we determined the effects of repeated UVB exposure 1kJ/m2 followed by heat (39°C) to human keratinocytes. Normal human ex vivo skin models …

Research outputs 2014 to 2021

Objective:

As the absence of Aβ-related memory decline in APOE ϵ4 noncarriers may be due to the relative brevity of previous studies, we aimed to characterize Aβ-related cognitive decline over 72 months in APOE ϵ4 carriers and noncarriers who were cognitively normal (CN).

Methods:

CN older adults (n 423) underwent Aβ imaging and APOE genotyping. Participants completed comprehensive neuropsychological testing at baseline 18-, 36-, 54-, and 72-month assessments.

Results:

Relative to Aβ- CN ϵ4 noncarriers, both Aβ+ CN ϵ4 carriers and noncarriers showed significantly increased decline in measures of memory, language, and executive function as well as higher rates of …

Developmental Transcription Factors In Age-Related Cns Disease: A Phoenix Rising From The Ashes?, Robert White, Meghan Thomas

Research outputs 2014 to 2021

Few would doubt that understanding the developmental landscape from which a mature neuron is derived is essential to understand its biology. The temporal and spatial position of a cell from the very earliest stages of development predicts the unique combinations of growth factors it will subsequently be exposed to. This combination of factors determines the transcriptional platform set within the cell by its specific combination of transcription factors, who direct the show. This, in turn, determines what cell type it will differentiate into, and what connections it will make. How this developmental platform translates to maintenance of a differentiated neuron …

Exercise Improves Physical Function And Mental Health Of Brain Cancer Survivors: Two Exploratory Case Studies, Gregory T. Levin, Kenneth M. Greenwood, Favil Singh, Daphne Tsoi, Robert U. Newton

Research outputs 2014 to 2021

Background

Malignant brain tumors are unpredictable and incurable, with 5-year survival rates less than 30%. The poor prognosis combined with intensive treatment necessitates the inclusion of complementary and supportive therapies that optimize quality of life and reduce treatment-related declines in health. Exercise therapy has been shown to be beneficial in other cancer populations, but no evidence is available for brain cancer survivors. Therefore, we report results from 2 preliminary cases.

Methods

Two female patients diagnosed with glioblastoma multiforme and oligodendroglioma participated in a structured and supervised 12-week exercise program. The program consisted of two 1-hour resistance and aerobic exercise sessions …

Research outputs 2014 to 2021

X-ray protective garments are typically comprised of lead-based materials, which are toxic to both people and the environment. Developing alternative lightweight radiation shielding materials is a priority for protecting people working with radiation. Gadolinium, with an electron configuration typical of radiation shielding elements, is proposed as a non-toxic replacement for lead. This study provides new insights into the potential for a gadolinium suspension for replacing lead and proposes an inexpensive and effective preparation method. Submicron gadolinium oxide (Gd2O3) was generated using a cost effective ball milling method involving addition of NaCl. Then, the dispersed-flocculated behaviour of …

Clinical Placement Before Or After Simulated Learning Environments? A Naturalistic Study Of Clinical Skills Acquisition Amongst Early-Stage Paramedicine Students, Brennen W. Mills Mr, Owen Carter A/Prof, Cobie Rudd Prof, Nathan Ross Mr, Louise Claxton Mrs Jul 2015

Clinical Placement Before Or After Simulated Learning Environments? A Naturalistic Study Of Clinical Skills Acquisition Amongst Early-Stage Paramedicine Students, Brennen W. Mills Mr, Owen Carter A/Prof, Cobie Rudd Prof, Nathan Ross Mr, Louise Claxton Mrs

eCULTURE

Background

There is conflicting evidence surrounding the merit of clinical placements (CP) for early-stage health-profession students. Some contend early-stage CPs facilitate contextualisation of subsequently learned theory. Others argue attending CP before attaining skills competency is problematic and should only occur after training in simulated-learning environments (SLE). The evidentiary basis surrounding the extent to which either is true remains limited.

Methods

First-year paramedicine students (n=85) undertook three days of CP and SLEs as part of course requirements. Students undertook CP either before or after participation in SLEs creating two groups (Clin→Sim/Sim→Clin). Clinical skills acquisition was measured via objectively-structured clinical examinations (OSCE) …

Using Eye Tracking, Time-To-Action, Heart-Rate And Perceived Task Difficulty To Assess Level Of Distraction And Performance Of Entry-Level Paramedicine Students In Low- Versus High-Fidelity Simulation, Owen Carter, Brennen W. Mills, Cobie Rudd, Natalie Strobel, Louise Claxton, Nathan Ross

eCULTURE

Introduction

There is limited research investigating the usefulness of high-fidelity simulations (HFS) for early-stage students. Some argue the additional expense of HFS over low-fidelity simulation (LFS) is unnecessary as early-stage students are too easily distracted by non-relevant stimuli inhibiting student’s ability to focus on the core task. However, the extent to which this is true is yet to be empirically tested.

Methods

First-year paramedicine students were randomly assigned to complete either a LFS or HFS involving a collapsed patient with an obstructed airway. Level of distraction was measured via eye-tracking, arousal via heart-rate (HR), task difficulty via the NASA TLX, …

The Clinical Utility Of Multidisciplinary Rehabilitation In Individuals With Huntington’S Disease, Travis Miles Cruickshank Jan 2015

The Clinical Utility Of Multidisciplinary Rehabilitation In Individuals With Huntington’S Disease, Travis Miles Cruickshank

Theses: Doctorates and Masters

Background

Huntington’s disease (HD) is a chronic neurodegenerative disorder characterised by a progressive loss of cognitive function, motor control and psychiatric features. Individuals also display a variety of systemic features. Progressive neuronal dysfunction and neuronal cell death are thought to underlie the onset and progression of many clinical features of HD.

Despite scientific progress, there is still no cure or disease modifying therapy for HD, and available pharmaceutical agents only provide partial relief of motor and psychiatric features. An emerging body of evidence indicates that lifestyle enrichment may delay the onset and progression of clinical features, and exert favourable effects …


Accurate Modelling And Positioning Of A Magnetically-Controlled Catheter Tip, Vi T. H. Le Jan 2015

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. …

Saying ‘No’: A Biographical Analysis Of The Experiences Of Women With A Genetic Predisposition To Developing Breast/Ovarian Cancer Who Reject Risk Reducing Surgery, Doreen Molloy

Theses: Doctorates and Masters

Background: Genetic technologies have identified some of the genes implicated in cancer susceptibility. Women with mutations in breast/ovarian cancer-susceptibility genes (BRCA1 and 2) have a lifetime combined risk of breast/ovarian cancer of more than 80%. Risk reducing surgery (RRS) reduces cancer risk by as much as 90% in high risk populations. Despite this, some BRCA1/2 mutation-positive women say no to RRS.

Purpose: To illuminate an understanding of why women at high risk of developing breast/ovarian cancer say no to risk reducing surgery (RRS).

Design: Denzin’s (1989) interpretive biography was combined with Dolby-Stahl’s (1985) literary folkloristic methodology to provide a contextualised …


Heat Stress: A Risk Factor For Skin Carcinogenesis, Leslie Calapre Jan 2015

Heat Stress: A Risk Factor For Skin Carcinogenesis, Leslie Calapre

Theses: Doctorates and Masters

BACKGROUND: The incidence of skin cancer in Australia has increased rapidly in the last few decades. Ultraviolet radiation (UV) is a major risk factor for skin carcinogenesis. UV, particularly the UVB spectrum, causes formation of cyclobutane pyrimidine dimers (CPD) in cellular DNA. Persistent and incorrectly repaired CPDs lead to DNA mutations and consequently, formation of cutaneous lesions. Interestingly, recent epidemiological studies have shown a significant increase in skin cancer incidence in geographical locations with high environmental temperatures. Thus, heat stress may potentiate the effects of UV exposure and act as an additional risk factor for skin cancer. Previous studies …

Integrating Psychosocial Care Into Neuro-Oncology: Challenges And Strategies, Suzanne K. Chambers, L. Grassi, M.K. Hyde, J. Holland, J. Dunn

Research outputs 2014 to 2021

Approximately 256,000 cases of malignant brain and nervous system cancer were diagnosed worldwide during 2012 and 189,000 deaths, with this burden falling more heavily in the developed world. Problematically, research describing the psychosocial needs of people with brain tumors and their carers and the development and evaluation of intervention models has lagged behind that of more common cancers. This may relate, at least in part, to poor survival outcomes and high morbidity associated with this illness, and stigma about this disease. The evidence base for the benefits of psychosocial care in oncology has supported the production of clinical practice guidelines …
