Inactivation Efficacy Of Atmospheric Air Plasma And Airborne Acoustic Ultrasound Against Bacterial Bioflms, Apurva Patange, Jeremy Simpson, James Curtin, Catherine Burgess, P.J. Cullen, Brijesh Tiwari

Articles

Bioflms are complex microbial communities that present serious contamination risks to our environment and health. In this study, atmospheric air plasma and airborne acoustic ultrasound technology were applied to inactivate Escherichia coli and Listeria innocua bioflms. Both technologies were efcient in controlling, or completely inactivating, the target bacterial bioflms. Viability and metabolic assays, along with microscopy analysis, revealed that atmospheric air plasma and airborne acoustic ultrasound damaged both the bacterial bioflm cells and its structural integrity. Scanning electron microscopy images highlighted the disruption of the bioflms and pore formation in bacterial cells exposed to both the plasma and acoustic treatments. …

Metal-Organic Frameworks As Bacteria Mimicking Delivery Systems For Tuberculosis, Ailin Guo Jan 2021

Metal-Organic Frameworks As Bacteria Mimicking Delivery Systems For Tuberculosis, Ailin Guo

Electronic Theses and Dissertations

Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis (M.tb), with an estimated 1.5 million deaths and 10 million infections each year. Although TB can be effectively treated with antibiotics, because of the complications and length of treatment, many people fail to complete the treatment which exacerbates the emergence of drug-resistant M. tb strains. The goal of this work is to develop biomimetic particles as host-directed therapy to target the infected macrophages. Two types of metal-organic frameworks (MOFs), MIL-100(Fe) and MIL-88A(Fe) were developed for bacteriamimicking particles. As a proof-of-concept, Mannose was selected as a ligand to target macrophages because …


Boosting And Lassoing New Prostate Cancer Snp Risk Factors And Their Connection To Selenium, David E. Booth, Venugopal Gopalakrishna-Remani, Matthew L. Cooper, Fiona R. Green, Margaret P. Rayman Jan 2021

Boosting And Lassoing New Prostate Cancer Snp Risk Factors And Their Connection To Selenium, David E. Booth, Venugopal Gopalakrishna-Remani, Matthew L. Cooper, Fiona R. Green, Margaret P. Rayman

Management Faculty Publications and Presentations

We begin by arguing that the often used algorithm for the discovery and use of disease risk factors, stepwise logistic regression, is unstable. We then argue that there are other algorithms available that are much more stable and reliable (e.g. the lasso and gradient boosting). We then propose a protocol for the discovery and use of risk factors using lasso or boosting variable selection. We then illustrate the use of the protocol with a set of prostate cancer data and show that it recovers known risk factors. Finally, we use the protocol to identify new and important SNP based risk …

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. There is increasing recognition of circulating tumour DNA (ctDNA) as a non-invasive alternative to tumour tissue for the molecular characterisation and monitoring of disease. Recent evidence suggests that cancer-associated changes can also be detected in the DNA contained within extracellular vesicles (EVs). As yet, there has been limited investigation into the relationship between EV DNA and ctDNA, and no studies have examined the EV DNA of breast cancer patients. The aim of this study was to use low-pass whole-genome sequencing to identify copy number variants (CNVs) in serial samples of both …

Research outputs 2014 to 2021

Introduction Frailty and pain are associated with adverse patient clinical outcomes and healthcare system costs. Frailty and pain can interact, such that symptoms of frailty can make pain assessment difficult and pain can exacerbate the progression of frailty. The prevalence of frailty and pain and their concurrence in hospital settings are not well understood, and patients with cognitive impairment are often excluded from pain prevalence studies due to difficulties assessing their pain. The aim of this study is to determine the prevalence of frailty and pain in adult inpatients, including those with cognitive impairment, in an acute care private metropolitan …

Widening The Lens On Capital: Conceptualising The University Experiences Of Non-Traditional Women Nurse Students, Lesley Andrew, Ken Robinson, Julie Dare, Leesa Costello

Research outputs 2014 to 2021

This article argues the insufficiency of the traditional application of cultural, social and economic capital in conceptualising the non-traditional student experience. Built on the thematic analysis of 52 in-depth interviews with 28 mature-age women nursing undergraduates with family responsibilities in Australia, an alternative, expanded model of capital is proposed.

The qualitative study, underpinned by Gadamer’s Hermeneutic Philosophy, revealed multiple threats and enablers to progression throughout the degree. Dimensions of capital previously unacknowledged in the nursing literature were necessary to fully conceptualise these rich and complex findings, including important student strengths. These dimensions: aspirational, navigational, resistant, familial and experiential capital, compensated …

An Outbreak Of Highly Pathogenic Avian Influenza (H7n7) In Australia And The Potential For Novel Influenza A Viruses To Emerge, Andrew T. Bisset, Gerard F. Hoyne

Research outputs 2014 to 2021

In 2020, several geographically isolated farms in Victoria, Australia, experienced an outbreak of highly pathogenic avian influenza (HPAI) virus H7N7 and low pathogenic avian influenza (LPAI) viruses H5N2 and H7N6. Effective containment and control measures ensured the eradication of these viruses but the event culminated in substantial loss of livestock and significant economic impact. The avian HPAI H7N7 virus generally does not infect humans; however, evidence shows the ocular pathway presents a favourable tissue tropism for human infection. Through antigenic drift, mutations in the H7N7 viral genome may increase virulence and pathogenicity in humans. The Victorian outbreak also detected LPAI …

Primary hypoadrenocorticism is characterized by insufficient adrenocortical hormonal secretion of glucocorticoids and mineralocorticoids, which causes unspecific signs and laboratory alterations such as hyponatremia and hyperkalemia, resulting in a low relation between these two electrolytes. The aim of this work was to carry out a retrospective study with data obtained from the medical records of 32 dogs with a proven diagnosis of hypoadrenocorticism between the years 2011 and 2018. The parameters weight, sex, reproductive condition, breed, and age were analyzed, as well as the results of laboratory tests of dogs with confirmed hypoadrenocorticism. There was no breed or sex predisposition. There …

The present study examined the variability of MHC class II DRB exon 2 gene using restriction fragment length polymorphism analysis of PCR-amplified fragments PCR-(RFLP), and its association with Haemonchus contortus infestation in Salem Black and Tellicherry goat population. Animals were naturally exposed to mixed infestation of endoparasites, predominantly Haemonchus contortus. Pooled fecal coproculture and larval identification showed predominant presence of haemonchus (L3) larva. Fecal egg count (FEC) and packed cell volume (PCV) were used as indicator traits. All the three studied loci, TaqI, BsaI, and BsaHI, were polymorphic having two alleles and three genotypes. The loci showed low to moderate …
