Research outputs 2022 to 2026

Lupin seeds have an excellent nutritional profile, including a high proportion of protein and dietary fiber. These qualities make lupin seeds an ideal candidate to help meet the growing global demand for complementary sources of protein. Of consequence to this application, there are nutritional and antinutritional properties assigned to the major lupin seed storage proteins—referred to as α-, β-, δ- and γ-conglutins The variation in the abundance of these protein families can impact the nutritional and bioactive properties of different lupin varieties. Hence, exploring the conglutin protein profiles across a diverse range of lupin varieties will yield knowledge that can …

Estropause, Sex Hormones And Metal Homeostasis In The Mouse Brain, Tianbing Liu, Richard L. Bowen, Andrea C. Wilson, Craig S. Atwood

Research outputs 2022 to 2026

Alterations in brain metal ion homeostasis have been reported with aging and are implicated in the pathogenesis of neurodegenerative diseases. To assess whether age-related changes in hypothalamic-pituitary-gonadal (HPG) hormones might be involved in modulating brain metal ion homeostasis, we treated 7.5-month intact, sham-ovariecomized and ovariectomized C57B6SJL mice with vehicle or leuprolide acetate (for 9-months) to differentiate between whether sex steroids or gonadotropins might modulate brain metal ion concentrations. Unlike other aging mammals, there was no increase in plasma luteinizing hormone (LH) and follicle-stimulating hormone (FSH) concentrations following estropause in mice, suggesting there was sufficient residual production by the follicle depleted …

Research outputs 2022 to 2026

SARS-CoV2, which causes coronavirus disease (COVID-19) is continuing to spread globally, producing new variants and has become a pandemic. People have lost their lives not only due to the virus but also because of the lack of counter measures in place. Given the increasing caseload and uncertainty of spread, there is an urgent need to develop robust artificial intelligence techniques to predict the spread of COVID-19. In this paper, we propose a deep learning technique, called Deep Sequential Prediction Model (DSPM) and machine learning based Non-parametric Regression Model (NRM) to predict the spread of COVID-19. Our proposed models are trained …

Dietary Iron And The Elite Dancer, Caitlin Attwell, Cory Dugan, Alannah K. A. Mckay, Joanna Nicholas, Luke Hopper, Peter Peeling

Research outputs 2022 to 2026

Dancers are an athlete population at high risk of developing iron deficiency (ID). The aesthetic nature of the discipline means dancers potentially utilise dietary restriction to meet physique goals. In combination with high training demands, this means dancers are susceptible to problems related to low energy availability (LEA), which impacts nutrient intake. In the presence of LEA, ID is common because of a reduced mineral content within the low energy diet. Left untreated, ID becomes an issue that results in fatigue, reduced aerobic work capacity, and ultimately, iron deficient anaemia (IDA). Such progression can be detrimental to a dancer’s capacity …

A Most Unusual Tail: Scoliosis In A Wild Australian Skink, And Reported Incidences And Suggested Causes Of Similar Malformations Amongst Squamates, Philip W. Bateman, Robyn Benken, Ryan Glowacki, Robert A. Davis

Research outputs 2022 to 2026

Malformations of vertebrae potentially occur across many taxa, particularly in Testudines, which are susceptible to kyphosis (dorsoventral curvature of the spine). Such malformations may stem from either genetic or environmental origins, and their prevalence and associated impacts on survival remain poorly understood. However, scoliosis (sideways curvature of the spine) is rarely reported and especially so in wild lizards. We report here on the first known case of scoliosis in a wild Australian lizard, the skink Ctenotus fallens, from Perth, Western Australia. This occurrence is the first of 805 individuals captured in a natural population monitored annually for the past 11 …

Effects Of Reciprocal Inhibition And Whole-Body Relaxation On Persistent Inward Currents Estimated By Two Different Methods, Ricardo N.O. Mesquita, Janet L. Taylor, Gabriel S. Trajano, Jakob Škarabot, Aleš Holobar, Basílio A. M. Gonçalves, Anthony J. Blazevich

Research outputs 2022 to 2026

Persistent inward currents (PICs) are crucial for initiation, acceleration, and maintenance of motoneuron firing. As PICs are highly sensitive to synaptic inhibition and facilitated by serotonin and noradrenaline, we hypothesised that both reciprocal inhibition (RI) induced by antagonist nerve stimulation and whole-bodyrelaxation (WBR) would reduce PICs in humans. To test this, we estimated PICs using the well-established paired motor unit (MU) technique. High-density surface electromyograms were recorded from gastrocnemius medialis during voluntary, isometric 20-s ramp, plantarflexor contractions and decomposed into MU discharges to calculate delta frequency (ΔF). Moreover, another technique (VibStim), which evokes involuntary contractions proposed to result from PIC …

Resistance Training Effectiveness On Body Composition And Body Weight Outcomes In Individuals With Overweight And Obesity Across The Lifespan: A Systematic Review And Meta-Analysis, Pedro Lopez, Dennis R. Taaffe, Daniel A. Galvão, Robert U. Newton, Elisa R. Nonemacher, Victória M. Wendt, Renata N. Bassanesi, Douglas J. P. Turella, Anderson Rech

Research outputs 2022 to 2026

To systematically review and analyze the effects of resistance-based exercise programs on body composition, regional adiposity, and body weight in individuals with overweight/obesity across the lifespan. Using PRISMA guidelines, randomized controlled trials were searched in nine electronic databases up to December 2020. Meta-analyses were performed using random-effects model. One-hundred sixteen articles describing 114 trials (n = 4184 participants) were included. Interventions involving resistance training and caloric restriction were the most effective for reducing body fat percentage (ES = −3.8%, 95% CI: −4.7 to −2.9%, p < 0.001) and whole-body fat mass (ES = −5.3 kg, 95% CI: −7.2 to −3.5 kg, p < 0.001) compared with groups without intervention. Significant results were also observed following combined resistance and aerobic exercise (ES = −2.3% and −1.4 kg, p < 0.001) and resistance training alone (ES = −1.6% and −1.0 kg, p < 0.001) compared with no training controls. Resistance training alone was the most effective for increasing lean mass compared with no training controls (ES = 0.8 kg, 95% CI: 0.6 to 1.0 kg, p < 0.001), whereas lean mass was maintained following interventions involving resistance training and caloric restriction (ES = ~ − 0.3 kg, p = 0.550–0.727). Results were consistently observed across age and sex groups (p = 0.001–0.011). Reductions in regional adiposity and body weight measures were also observed following combined resistance and aerobic exercise and programs including caloric restriction (p < 0.001). In conclusion, this study provides evidence that resistance-based exercise programs are effective and should be considered within any multicomponent therapy program when caloric restriction is utilized in individuals with overweight or obesity.

Research outputs 2022 to 2026

Objective: Women with threatened preterm labor in remote Australia often require tocolysis in the prevention of in-flight birth during air medical retrieval. However, debate exists over the tocolytic choice. Methods: A retrospective analysis was undertaken on data containing women who required air medical retrieval for threatened preterm labor within Western Australia between the years 2013 and 2018. Results: A total number of 236 air medical retrievals were deemed suitable for inclusion; 141 received nifedipine, and 95 women received salbutamol + nifedipine. Tocolytic efficaciousness was reported in 151 cases, proportionally more (P < .05) from the women who received salbutamol + nifedipine (n = 68, 71.6%) compared with the women who received nifedipine only (n = 83, 58.9%). Those receiving salbutamol + nifedipine were more likely to suffer maternal tachycardia (n = 87 [91.6%] vs. n = 62 [44.0%]), fetal tachycardia (n = 26 [27.4%] vs. n = 13 [9.2%]), nausea (n = 17 [17.9] vs. n = 5 [3.55%]), and vomiting (n = 12 [12.6%] vs. n = 2 [1.4%]). Three women who received salbutamol + nifedipine had serious side effects including echocardiographic changes, chest pain, and metabolic and lactic acidosis. Conclusion: Salbutamol + nifedipine tocolysis was proven to be more effective than nifedipine only. Although salbutamol + nifedipine had increased temporary side effects, most were nonsevere and managed in-flight.

Review On Physical And Chemical Factors Affecting Fines Migration In Porous Media, Yulong Yang, Weifeng Yuan, Jirui Hou, Zhenjiang You

Research outputs 2022 to 2026

Permeability reduction and formation damage in porous media caused by fines (defined as unconfined solid particles present in the pore spaces) migration is one of the major reasons for productivity decline. It is well accepted that particle detachment occurs under imbalanced torques arising from hydrodynamic and adhesive forces exerted on attached particles. This paper reviewed current understanding on primary factors influencing fines migration as well as mathematical formulations for quantification. We also introduced salinity-related experimental observations that contradict theoretical predictions based on torque balance criteria, such as delayed particle release and attachment-detachment hysteresis. The delay of particle release during low-salinity …
