Exploring The Dairy Milk Matrix Beyond Isolated Nutrients—A Narrative Review, Therese A. O’Sullivan, Analise Nicholl

Research outputs 2022 to 2026

The concept of the food matrix considers individual components along with how they are structured, interact, and are modified during processing. There is increasing interest around the health effects of individual nutrients versus whole foods, creating a need to better understand how the matrix may influence health outcomes. This narrative review explores the dairy milk matrix and compares health effects with those of isolated components, with additional comparisons to plant-based milk alternatives. Comparative evidence suggests that while calcium from food and supplements generally has similar effects (depending on the form of the supplemental calcium), consumption of food-based sources such as …

The First Systematic Review Of Treatment Characteristics And Recidivism Outcomes For Indigenous People Who Have Sexually Offended, James L. Finney, Natalie Gately, Suzanne Rock, Braden Hill

Research outputs 2022 to 2026

It is of great importance that research investigates the impact of sexual offender treatment programmes given the damage caused by sexual offences to victims and society more broadly. However, psycho-criminological literature has focused on reporting post-treatment recidivism outcomes for people who have sexually offended homogeneously and has not investigated the unique experiences of Indigenous people. Therefore, we systematically collated and critically appraised studies reporting recidivism outcomes for Indigenous people who have received treatment for sexual offences. Fourteen studies were identified utilising a sample of 5,635 individuals (30.7% Indigenous or First Nations). Recidivism was lower for Indigenous and First Nations people …

A Knowledge-Driven, Ai-Assisted Cyber Defence Framework For Iomt Remote Patient Monitoring, Kulsoom S. Bughio, David M. Cook, Abdul M. Unar

Research outputs 2022 to 2026

The rapid adoption of Internet Medical Things (IoMT) technologies in remote patient monitoring has reshaped healthcare delivery by enabling continuous, real-time clinical observation outside traditional care settings. However, this shift has also expanded the cyber-attack surface across heterogeneous, resource-constrained medical devices, wireless networks, cloud services, and third-party platforms. In cyber warfare, healthcare has become an incorporated target of geopolitics, with hospitals, remote monitoring systems, and emergency health systems being used to broaden the attack surface for adversaries to exploit. Existing security approaches for IoMT environments remain largely manual, fragmented, and reactive, limiting their effectiveness in dynamically assessing vulnerabilities and supporting …

A Survey-Based Assessment Of Treatment Preferences For Distal Radius Fractures In Participants Aged 65 Years And Older, Zayd Al Rawi, Elizabeth Graesser, Lindley B Wall

2020-Current year OA Pubs

PURPOSE: The management of distal radius fractures (DRF) in patients aged ≥65 years is debated because there is evidence that operative and nonsurgical treatment yield similar outcomes 1 year after injury. When more than one reasonable treatment option exists, shared decision-making between the patient and physician should be used. This study elicited preferences for the treatment of DRF using a survey of participants aged ≥65 years.

METHODS: A survey for participants ≥65 years was administered using Amazon Mechanical Turk. Participants were presented with a theoretical scenario in which they sustained a DRF, followed by two treatment options (surgery or casting) …

2020-Current year OA Pubs

Propionibacteriaceae appear to have adapted to life on humans during the domestication of cattle. These microbial immigrants formed the genus Cutibacterium, and a descendent of those microbial trailblazers (C acnes) now dominates 25% of human skin. C acnes colonization of human skin requires the protein RoxP. Although all Cutibacteria encode this adaptation to life on humans, nothing like RoxP has been found in any other organism. In this study, we report an extensive assessment of 21 RoxP orthologs, which identified conserved molecular surfaces linked to heme-dependent oligomerization and low pH stability. Our investigation suggests how RoxP helps C acnes dominate …

Coordinated Regulation Of Capping Protein By Carmil And V-1/Myotrophin, John A Hammer, John A Cooper

2020-Current year OA Pubs

Capping Protein (CP) plays a central role in controlling actin filament dynamics in almost all eukaryotic cell types by virtue of its ability to block monomer addition and loss at the barbed end of the actin filament. Like other proteins that control actin assembly, CP is subject to regulation. Here we focus on two direct regulators of CP-CARMIL and V-1/Myotrophin. Specifically, we review recent biochemical, structural, imaging, and cell biological data that argue these two proteins cooperate to create a regulatory cycle for CP that controls its availability, activity, and site of action in the cell. Finally, we discuss unresolved …

Mutations In Hsp40 Co-Chaperone Change The Canonical Interdomain Interactions Stimulating Lgmdd1 Myopathy, Ankan K Bhadra, Geetika Aggarwal, Anshuman Jaysingh, Daniel Chen, Jil Daw, Conrad C Weihl, Heather L True

2020-Current year OA Pubs

Limb-girdle muscular dystrophy D1 (LGMDD1) is a rare, dominantly inherited neuromuscular protein-misfolding chaperonopathy caused by mutations in the Hsp40 co-chaperone DNAJB6, primarily in the glycine-phenylalanine (GF) or J-domains. Currently, no treatments are available, and a challenge in understanding the disease is identifying a specific client protein for DNAJB6 in skeletal muscle. DNAJB6 has homology to the yeast DNAJ family member, Sis1. Our previous research indicated that LGMDD1 GF domain mutants in Sis1 exhibit substrate-specific effects, influenced by Hsp70 activity. Herein, we employed functional assays along with advanced molecular simulation studies to understand the regulatory interdomain interactions in disease-causing mutants of …

Airway Management In Emergency Department Thoracotomy: A Narrative Review, Aaron J Lacy, Adam Liebendorfer, Sarah M Guess, Rami S Al-Aref, Anthony P Kronfli, Rachel E Armstrong, Amelia W Maiga, Alexander Bracey, Ryan N Barnicle

2020-Current year OA Pubs

INTRODUCTION: Emergency department thoracotomy (EDT) is a high-risk, life-saving intervention for patients in traumatic cardiac arrest. A critical component of EDT is airway management, typically performed by emergency physicians, yet formal guidance regarding optimal strategies remains limited. Airway management in this setting is uniquely complex due to concurrent anatomic injury, physiologic instability, and the procedural demands of thoracotomy.

DISCUSSION: Endotracheal intubation (ETI) during EDT presents multiple challenges. Anatomic difficulties may arise from facial or cervical trauma, restricted positioning, and the presence of cervical collars. Cognitive load is heightened by the chaotic, multidisciplinary environment, requiring strategies such as pre-briefing, checklists, and …

Satellite Observations Reveal Ecosystem Resistance And Resilience To Short-Term Water Stress Driven By Dominant Vegetation Along A Rainfall Gradient In Australia, Huanhuan Wang, Qiaoyun Xie, Sally E. Thompson, Caitlin E. Moore, David L. Miller, Erik J. Veneklaas, Richard P. Silberstein, Xing Li, Jingfeng Xiao, Belinda E. Medlyn, William K. Smith

Research outputs 2022 to 2026

Climate change is projected to intensify water stress in many ecosystems and poses threats to their stability, which can be quantified through ecosystem resistance and resilience. Relevant studies mostly focused on multi-year or annual droughts, and in spatially homogeneous or species-specific ecosystems. However, resilience and resistance within complex ecosystems, where different plants exhibit different adaptations and recovery behaviours, are less understood. Using productivity data from satellite-derived GOSIF (Global Orbiting Carbon Observatory-2 Solar-Induced Fluorescence) and flux towers, we examined vegetation responses to short-term (<1 year) water stress events from 2000 to 2018 along the North Australia Tropical Transect, which spans a 1600 mm rainfall gradient and transitions from seasonal mesic to non-seasonal arid ecosystems. We define resistance as productivity maintained during stress relative to a multi-year average baseline, and resilience as the extent to which productivity recovered one year after stress relative to the same baseline. Our results show that ecosystem resistance to water stress was lowest in semi-arid regions but higher in both arid and mesic regions, while ecosystem resilience showed the opposite pattern. These spatial patterns occurred regardless of seasonality and were mainly associated with dominant vegetation type. Woody savanna-dominated mesic regions exhibited highest resistance (0.82 ± 0.13, p < 0.001) and lowest resilience (0.26 ± 0.19, p < 0.001), shrublands in arid areas had intermediate values of both resistance (0.81 ± 0.14, p < 0.001) and resilience (0.27 ± 0.22, p < 0.001), while the grasslands in semi-arid regions had low resistance (0.78 ± 0.15, p < 0.001) and high resilience (0.38 ± 0.24, p < 0.001). The highest likelihood (>75.0 %) of full recovery (i.e., exceeding baseline after one year) occurred during the wet season in …
