A Platform As A Service Framework For Ambient Assisted Living Services, Hendrik Dr. Kuijs

School of Engineering, Computing and Mathematics Theses

The primary objective of Ambient Assisted Living (AAL) technology is to provide aid and assistance to individuals, particularly the elderly, in maintaining their independence and residing in their own homes and their known environment for an extended duration. AAL technology is becoming increasingly important due to the continuous decrease of birth-rate and increasing life expectancy, leading to a shrinking proportion of younger population in developed countries. This research proposes a cloud-based platform as a service (PaaS) for AAL that enables service providers to deliver services without the need for the user to invest in expensive technical equipment in advance, thus …

Research outputs 2022 to 2026

Osteoporosis and Alzheimer’s disease (AD) mainly affect older individuals, and the possibility of an underlying link contributing to their shared epidemiological features has rarely been investigated. In the current study, we investigated the association between levels of plasma sclerostin (SOST), a protein primarily produced by bone, and brain amyloid-beta (A ) load, a pathological hallmark of AD. The study enrolled participants meeting a set of screening inclusion and exclusion criteria and were stratified into A − (n = 65) and A + (n = 35) according to their brain A load assessed using A -PET (positron emission tomography) imaging. Plasma …

Care Visits: Obligations, Opportunities And Constraints For Vietnamese Grandparent Visitors In Australia, Hien Thi Nguyen, Loretta Baldassar, Raelene Wilding

Research outputs 2022 to 2026

In examining the ageing-migration nexus from a Global South perspective, this paper explores the obligations, opportunities and constraints of caregiving performed by Vietnamese grandparent visitors during their sojourns in Australia. Employing a grounded theory approach and care circulation framework, we investigate how grandparent visitors and adult migrant children experience and understand care and ageing in contexts of mobility, including an analysis of how gender, age, socio-economic contexts and culture shape and affect their care norms and practices. The analysis emphasizes the critical contributions that Vietnamese grandparents make to the reproductive labour of their adult migrant children who often face challenges …

Dual-Task Upper Extremity Motor Performance Measured By Video Processing As Cognitive-Motor Markers For Older Adults, Changhong Wang, Mohsen Zahiri, Ashkan Vaziri, Bijan Najafi

Center on Aging Staff Publications

Introduction: The use of dual-task model such as dual-task gait has been extensively studied to assess cognitive-motor performance among older adults. However, space restriction and safety factor limit its applications in remote assessment. To address the gap, we propose a video processing-based approach to remotely quantify cognitive-motor performance using a 20-s repetitive elbow flexion-extension test with dual-task condition, called video-based motoric-cognitive meter (MCM).

Methods: Eighteen older participants (age: 78.6 ± 6.5 years) who were clinically diagnosed as having either mild cognitive impairment or dementia were included in this study. Participants were asked to perform 20-s repetitive elbow flexion-extension exercise with …

INTRODUCTION: Many studies in mice have demonstrated that cardiac-specific innate immune signaling pathways can be reprogrammed to modulate inflammation in response to myocardial injury and improve outcomes. While the echocardiography standard parameters of left ventricular (LV) ejection fraction, fractional shortening, end-diastolic diameter, and others are used to assess cardiac function, their dependency on loading conditions somewhat limits their utility in completely reflecting the contractile function and global cardiovascular efficiency of the heart. A true measure of global cardiovascular efficiency should include the interaction between the ventricle and the aorta (ventricular-vascular coupling, VVC) as well as measures of aortic impedance and …

Is Growth Hormone The Fountain Of Youth?, David Youlus

The Science Journal of the Lander College of Arts and Sciences

Finding the cure for aging has been a sought-after quest for as long as the world has existed. Growth hormone has been shown as a possible treatment to negate the phenotypic effects of aging. Growth hormone is released from the adenohypophysis in response to sleep, exercise and stress. This in turn stimulates insulin-like growth factor-1 (IGF-1) secretion from the liver. Growth hormone circulation decreases in volume during aging. Studies on growth hormone therapy have indicated youth-like benefits, such as the reversal of sarcopenia, improved cognitive function, and boosted immunity. However, creating an imbalance of growth hormone and insulin-like factor-1 also …
