Research outputs 2022 to 2026

Background:

Men are often viewed as a difficult group to recruit for psychological research, including in psycho-oncology. Whilst research has demonstrated the effectiveness of small monetary incentives for encouraging research participation, little research has examined different large unconditional incentive amounts. Larger unconditional incentives may result in increased participation of men in psychological research. This randomised study within a case–control trial of men diagnosed with early-stage prostate cancer aimed to investigate whether (a) response rates to a 30-min questionnaire completed via mail, online, or phone would vary with different unconditional incentive amounts, and (b) demographics would vary in those who responded …

Nethnography, Complementing Netnography: A Defensible Praxis For The Online Researcher, Martin Maccarthy Sep 2022

Nethnography, Complementing Netnography: A Defensible Praxis For The Online Researcher, Martin Maccarthy

Research outputs 2022 to 2026

This article issues a challenge for interpretive tourism researchers to consider the trove of online data currently disavowed by aficionados of Netnography. Non-dyadic social media data is used by researchers but has been devalued as lacking legitimacy. However, by combining ‘lifeless’ non-dyadic social media with lesser-engaged ethnographic methods a lived proxy can be achieved. Nethnography is a two-part qualitative praxis of spending enough time with the phenomenon to discern meanings with confidence, which is then used to interpret non-dyadic textual discourse. Lesser-engaged ethnographic methods include participants as observers, observers as participants and complete observers. A fourth legitimizer of online interpretation …

Ridinilazole: A Novel, Narrow-Spectrum Antimicrobial Agent Targeting Clostridium (Clostridioides) Difficile, Deirdre A. Collins, Thomas V. Riley

Research outputs 2022 to 2026

Clostridium (Clostridioides) difficile infection (CDI) remains an urgent threat to patients in health systems worldwide. Recurrent CDI occurs in up to 30% of cases due to sustained dysbiosis of the gut microbiota which normally protects against CDI. Associated costs of initial and recurrent episodes of CDI impose heavy financial burdens on health systems. Vancomycin and metronidazole have been the mainstay of therapy for CDI for many years; however, these agents continue to cause significant disruption to the gut microbiota and thus carry a high risk of recurrence for CDI patients. Treatment regimens are now turning towards novel narrow spectrum antimicrobial …

System Archetypes Underlying Formal-Informal Urban Water Supply Dynamics, Rakhshinda Bano, Mehdi Khiadani, Yong Saebastian Nyam

Research outputs 2022 to 2026

Contrary to developed countries, developing countries have been observed to have an increased reliance on a diversity of water supply options to meet their daily demands, where formal supply systems are incapable of fulfilling the daily needs of consumers. In filling a demand-supply gap, informal supply systems are increasingly being associated with issues of long-term sustainability, higher consumer cost, and inequity. Emerging formal-informal dynamics in developing countries require a thorough understanding of complex human-water interactions for policy direction, in order to best support the advancement of urban water sustainability. Accordingly, system archetypes offer a platform to explain the behaviors of …

Sleep, Sirtuin 1 And Alzheimer’S Disease: A Review, Mehrane Mehramiz, Tenielle Porter, Simon Laws, Stephanie R. Rainey-Smith

Research outputs 2022 to 2026

Sleep plays a major role in brain health, and cognition. Disrupted sleep is a well-described symptom of Alzheimer’s disease (AD). However, accumulating evidence suggests suboptimal sleep also increases AD risk. The deacetylase Sirtuin 1 (Sirt 1), encoded by the SIRT1 gene, impacts sleep via its relationship to wake-sleep neurotransmitters and somnogens. Evidence from animal and human studies supports a significant and complex relationship between sleep, Sirt 1/ SIRT1 and AD. Numerous hypotheses attempt to explain the critical impact of Sirt 1/ SIRT1 on wake- and sleep- promoting neurons, their related mechanisms and neurotransmitters. However, there is a paucity of studies …

Research outputs 2022 to 2026

Evidence suggests that hearing loss (HL), even at mild levels, increases the long-term risk of cognitive decline and incident dementia. Hearing loss is one of the modifiable risk factors for dementia, with approximately 4 million of the 50 million cases of dementia worldwide possibly attributed to untreated HL. This paper describes four possible mechanisms that have been suggested for the relationship between age-related hearing loss (ARHL) and Alzheimer's disease (AD), which is the most common form of dementia. The first mechanism suggests mitochondrial dysfunction and altered signal pathways due to aging as a possible link between ARHL and AD. The …

Hamstrings Force-Length Relationships And Their Implications For Angle-Specific Joint Torques: A Narrative Review, Eleftherios Kellis, Anthony J. Blazevich

Research outputs 2022 to 2026

Temporal biomechanical and physiological responses to physical activity vary between individual hamstrings components as well as between exercises, suggesting that hamstring muscles operate differently, and over different lengths, between tasks. Nevertheless, the force-length properties of these muscles have not been thoroughly investigated. The present review examines the factors influencing the hamstrings’ force-length properties and relates them to in vivo function. A search in four databases was performed for studies that examined relations between muscle length and force, torque, activation, or moment arm of hamstring muscles. Evidence was collated in relation to force-length relationships at a sarcomere/fiber level and then moment …

Broadly neutralizing antibodies (bNAbs) that target the membrane-proximal external region (MPER) of HIV gp41 envelope, such as 4E10, VRC42.01 and PGZL1, can neutralize > 80 % of viruses. These three MPER-directed monoclonal antibodies share germline antibody genes (IGHV1 - 69 and IGKV3 - 20) and form a bNAb epitope class. Furthermore, convergent evolution within these two lineages towards a 111.2GW111.3 motif in the CDRH3 is known to enhance neutralization potency. We have previously isolated an MPER neutralizing antibody, CAP206 - CH12, that uses these same germline heavy and light chain genes but lacks breadth (neutralizing only 6 % of …
