Research outputs 2014 to 2021

INTRODUCTION: The global burden of type 2 diabetes (T2DM) is steadily increasing. Experimental studies have demonstrated that a novel hormone secreted by bone cells, osteocalcin (OC), can stimulate beta-cell proliferation and improve insulin sensitivity in mice. Observational studies in humans have investigated the relationship between OC and metabolic parameters, and T2DM. Importantly, few studies have reported on the undercarboxylated form of OC (ucOC), which is the putative active form of OC suggested to affect glucose metabolism.

OBJECTIVES: We will conduct a systematic review and meta-analysis to: (1) compare the levels of serum OC and ucOC between T2DM and normal glucose-tolerant …

Vibrio cholerae is the causative agent of cholera, a globally important human disease for at least 200 years. In 2009-2011, the first recorded cholera outbreak in Papua New Guinea (PNG) occurred. We conducted genetic and phenotypic characterization of 21 isolates of V. cholerae, with whole-genome sequencing conducted on 2 representative isolates. The PNG outbreak was caused by an atypical El Tor strain harbouring a tandem repeat of the CTX prophage on chromosome II. Whole-genome sequence data, prophage structural analysis and the absence of the SXT integrative conjugative element was indicative that the PNG isolates were most closely related to strains …

Treatment Fidelity In Aphasia Randomised Controlled Trials, Emily Brogan, Natalie Ciccone, Erin Godecke

Research outputs 2014 to 2021

Background: Treatment fidelity is at the heart of evidence-based practice and treatment fidelity processes help to determine the ‘active ingredients’ of a treatment. Hinckley and Douglas in 2013 reviewed treatment fidelity processes in published aphasia trials and found 14% of aphasia treatment studies reported treatment fidelity. This led the authors to call for journals to make treatment fidelity reporting mandatory.

Aims: To review the implementation and reporting of treatment fidelity processes in recent aphasia RCTs to update on practices since 2012.

Methods and Procedures: Aphasia RCTs published between 2012 and 2017 were sourced from online databases speechBITE, …

A Paleolithic Diet Lowers Resistant Starch Intake But Does Not Affect Serum Trimethylamine-N-Oxide Concentrations In Healthy Women, Angela Genoni, Johnny Lo, Philippa Lyons-Wall, Mary C. Boyce, Claus T. Christophersen, Anthony Bird, Amanda Devine

Research outputs 2014 to 2021

The Paleolithic diet excludes two major sources of fibre, grains and legumes. However, it is not known whether this results in changes to resistant starch (RS) consumption. Serum trimethylamine-N-oxide (TMAO) is produced mainly from colonic fermentation and hepatic conversion of animal protein and is implicated in CVD, but changes in RS intake may alter concentrations. We aimed to determine whether intake of RS and serum concentrations of TMAO varied in response to either the Paleolithic or the Australian Guide to Healthy Eating (AGHE) diets and whether this was related to changes in food group consumption. A total of thirty-nine women …

Elbow Angle Modulates Corticospinal Excitability To The Resting Biceps Brachii At Both Spinal And Supraspinal Levels, Siobhan C. Dongés, Janet L. Taylor, James L. Nuzzo

Research outputs 2014 to 2021

NEW FINDINGS:

What is the central question of this study?

Corticospinal excitability to biceps brachii is known to modulate according to upper-limb posture. Here, cervicomedullary stimulation was used to investigate potential spinal contributions to elbow angle-dependent changes in corticospinal excitability at rest.

What is the main finding and its importance?

At more extended elbow angles, biceps responses to cervicomedullary stimulation were decreased, whereas cortically evoked responses (normalized to cervicomedullary-evoked responses) were increased. Results suggest decreased spinal excitability but increased cortical excitability as the elbow is placed in a more extended position, an effect that is unlikely to be attributable to …

Genetic variation conferring resistance and susceptibility to carcinogen-induced tumorigenesis is frequently studied in mice. We have now turned this idea to melanoma using the collaborative cross (CC), a resource of mouse strains designed to discover genes for complex diseases. We studied melanoma-prone transgenic progeny across seventy CC genetic backgrounds. We mapped a strong quantitative trait locus for rapid onset spontaneous melanoma onset to Prkdc, a gene involved in detection and repair of DNA damage. In contrast, rapid onset UVR-induced melanoma was linked to the ribosomal subunit gene Rrp15. Ribosome biogenesis was upregulated in skin shortly after UVR exposure. …

Research outputs 2014 to 2021

Peer bullying in schools is a significant public health problem that contributes to poor health and wellbeing outcomes for those who bully or are bullied. Meta-analyses of the efficacy of secondary school bullying prevention interventions have typically found no effects or an increase in student bullying. Consequently, few secondary school studies have examined the “real-world” effectiveness of these interventions. This age-cohort study design evaluated the effectiveness of the Friendly Schools (FS) secondary school intervention, previously found to be efficacious. FS was implemented in schools under real-world conditions by an education publisher. Student survey data were collected in 12 schools. The …

Altering Brain Dynamics With Transcranial Random Noise Stimulation, Onno Van Der Groen, Jason B. Mattingley, Nicole Wenderoth

Research outputs 2014 to 2021

Random noise can enhance the detectability of weak signals in nonlinear systems, a phenomenon known as stochastic resonance (SR). This concept is not only applicable to single threshold systems but can also be applied to dynamical systems with multiple attractor states, such as observed during the phenomenon of binocular rivalry. Binocular rivalry can be characterized by marginally stable attractor states between which the brain switches in a spontaneous, stochastic manner. Here we used a computational model to predict the effect of noise on perceptual dominance durations. Subsequently we compared the model prediction to a series of experiments where we measured …

Background: Esophageal cancer (EC) causes more than 400 thousand deaths per year, and half of them occur in China. There are discrepancies regarding the survival of EC patients between population-based surveillance studies and hospital-based studies.

Objectives: We aimed to synthesize the survival data from hospital-based EC studies in the Chinese population from 2000 to 2018 and to compare the survival rates between EC patients with different clinical classifications.

Methods: The protocol of this systematic review was registered in PROSPERO (CRD-42019121559). We searched Embase, PubMed, CNKI, and Wanfang databases for studies published between January 1, 2000 and December 31, 2018. We …

Arthrofibrosis is a fibrotic joint disorder that begins with an inflammatory reaction to insults such as injury, surgery and infection. Excessive extracellular matrix and adhesions contract pouches, bursae and tendons, cause pain and prevent a normal range of joint motion, with devastating consequences for patient quality of life. Arthrofibrosis affects people of all ages, with published rates varying. The risk factors and best management strategies are largely unknown due to a poor understanding of the pathology and lack of diagnostic biomarkers. However, current research into the pathogenesis of fibrosis in organs now informs the understanding of arthrofibrosis. The process begins …
