PolyU researchers develop novel selenium nanoparticles for managing postmenopausal osteoporosis

As the aging population around the world grows, metabolic diseases like osteoporosis are becoming more prevalent and placing a greater burden on healthcare systems. Rising to this challenge, a research team led by Prof. WONG Ka-hing, Director of the Research Institute for Future Food and Professor of the Department of Food Science and Nutrition at The Hong Kong Polytechnic University (PolyU), has developed novel selenium nanoparticles (Cs4-SeNPs) for managing postmenopausal osteoporosis. The latest research findings were recently published in Journal of Functional Foods. This patented nanotechnology has also gained wide recognition, leading to various national and international awards, including the Ministry of Education’s Higher Education Outstanding Scientific Research Output Awards (Science and Technology) 2020: Second-Class Award in Technological Innovation. Selenium (Se) is an essential trace mineral for human health, playing important roles in many physiological functions. In the past decades, substantial evidence has demonstrated that Se deficiency is detrimental to bone microarchitecture and is associated with osteoporosis, suggesting its crucial role in bone metabolism. Recently, selenium nanoparticles (SeNPs) have become a new target of research, since they were found to possess remarkable bioactivity and lower toxicity compared to selenocompounds commonly found in foods. However, scientific research concerning their effects on bone health is currently very limited. Cordyceps sinensis (Berk.) Sacc. is a medicinal fungus which has been long used as a tonic and therapeutic agent. By using polysaccharide–protein complexes (PSPs) isolated from the C. sinensis mycelium (Cs4) and a previously patented nanotechnology, the research team has recently prepared novel selenium nanoparticles with a uniform structure and high stability (Cs4-SeNPs). In experiments using pre-osteoblast murine MC3T3-E1 cells, the research team demonstrated that Cs4-SeNPs were taken up rapidly and efficiently by the cells. Treatment with Cs4-SeNPs (10µM) increased proliferation of the MC3T3-E1 cells and promoted their differentiation to mature osteoblasts. Enhancement of bone mineralization of the MC3T3-E1 cells was also observed, indicating the promoting effect of Cs4-SeNPs on new bone formation. Further investigation of their action mechanism revealed that Cs4-SeNPs induced the production of physiological levels of reactive oxygen species to trigger osteoblast differentiation. Interestingly, comparison of these effects with those of common selenocompounds found that only Cs4-SeNPs showed significant osteogenic activity, and it was less toxic to the cells. More importantly, Cs4-SeNPs (25-500μg/kg BW/day) exhibited promising in vivo bone protective efficacy against OVX-induced osteoporosis by promoting bone formation, inhibiting bone resorption, and improving bone microarchitecture after oral gavage for 6 weeks. The team is currently working with local industry partners to bring the resulting health food products to market. Prof. Wong said, “The novel nano-mineral Cs4-SeNPs has a wide spectrum of health promotion and disease prevention applications, not just for postmenopausal osteoporosis management. Apart from developing a high-quality, safe and evidence-based bone protective agent to improve the quality of life of postmenopausal osteoporosis patients, our team is now investigating the effects of Cs4-SeNPs on treating Parkinson’s disease and more. We hope to tap into its potential biomedical value through interdisciplinary collaboration, thus further promoting research and applications in related fields.”   ***END***

PolyU develops first-of-its-kind multimodal robot empowering post-stroke ankle-foot telerehabilitation

The Hong Kong Polytechnic University (PolyU) has achieved another breakthrough in rehabilitation device development. The Mobile Ankle-foot Exoneuromusculoskeleton is the first-of-its-kind multimodal robot for ankle-foot rehabilitation specifically designed for stroke patients with hemiplegia, which helps improve the motor function of their lower limb and walking ability. Powered by Internet of Things (IoT) technology, the device enables telerehabilitation for remote management of patients’ rehabilitation progress and allows them to undertake self-help rehabilitation exercises at home. Therapists can remotely monitor the rehabilitation progress of multiple patients. In recent years, Hong Kong has seen around 50,000 new cases of stroke annually, with 85% of patients experiencing varying degrees of impaired physical mobility. Regular, repeated and intensive rehabilitation training is critical for restoring the physical mobility of stroke patients, thereby alleviating post-stroke symptoms such as disability. However, due to overwhelming demand, access to daytime outpatient rehabilitation services in local hospitals and rehabilitation clinics is challenging. Consequently, stroke patients are often unable to undergo timely and routine rehabilitation exercises. Common functional impairments among stroke patients include foot drop and inversion, which significantly disrupt their daily lives. Developed by a research team led by Dr Hu Xiaoling, Associate Professor of the Department of Biomedical Engineering of PolyU, the Mobile Ankle-foot Exoneuromusculoskeleton is an innovative multimodal wearable robot for ankle-foot rehabilitation that integrates the advantages of exoskeleton, soft pneumatic muscles, tactile sensory feedback and neuromuscular electrical stimulation technology in one system. The device can not only correct foot drop and foot inversion effectively, but also improve the gait of stroke patients. Additionally, it can help improve balance while walking and contribute to rehabilitative neuroplasticity in the long term. Stroke patients with hemiplegia generally have weakened muscle strength and discoordination at their affected lower limb, especially in the foot and ankle. The Mobile Ankle-foot Exoneuromusculoskeleton can automatically detect patients’ gait events including the standing state, heel strike, heel off and toe off. The multimodal assistance from the device can help a patient stand firm on their affected foot with mechanical support from the exoskeleton and soft pneumatic muscles, learn to balance the plantar pressure and exert propelling force when walking with the vibration tactile feedback and neuromuscular electrical stimulation, and improve foot drop with the neuromuscular electrical stimulation. The Mobile Ankle-foot Exoneuromusculoskeleton features a lightweight design weighing about 400g which, together with its sportswear features, makes it more suitable for the hemiplegic patients to wear it unilaterally on their own. This device also has the advantage of low power consumption and can be used continuously for four hours with a 9V rechargeable battery, enabling patients to practice anytime, anywhere – at home, outdoors, or indoors. Other exoskeleton lower-limb robots available on the market, which rely solely on external force to assist patients in walking, they are of very limited value in improving ankle joint and muscle coordination for stroke patients with hemiplegia. These robots are also limited to use in hospitals and rehabilitation clinics due to their high weight and power consumption. As for conventional ankle-foot orthoses, these are prone to causing muscle atrophy and interference to patients regaining voluntary motor control over the ankle of the affected leg. Dr Hu stated, “Combining the research capabilities of the Department of Biomedical Engineering, Industrial Centre, School of Fashion and Textiles and Department of Computing, the Mobile Ankle-foot Exoneuromusculoskeleton is a testament to PolyU’s exceptional strength in interdisciplinary research. This research achievement provides stroke patients a better option for lower limb rehabilitation training, incorporating the training into their daily activities. It also enables therapists to provide tele-supervision of the rehabilitation progress of multiple patients. We hope such flexible self-help training can effectively supplement traditional outpatient rehabilitation services, helping stroke patients achieve more efficient rehabilitation progress.” Dr Hu’s research team is collaborating with several local and Mainland hospitals and rehabilitation clinics to conduct clinical studies on the Mobile Ankle-foot Exoneuromusculoskeleton. Research studies have confirmed that rehabilitation training for stroke patients using the device is 40% more effective for stroke rehabilitation than applying external mechanical forces alone. Among the 12 patients participating in the clinical studies who completed a 1.5-month training programme consisting of 20 one-and-a-half-hour sessions, ankle dorsiflexion improved from an initial five degrees to 10 degrees without equipment assistance, approaching the normal level of 15 degrees. In addition, more than 90% of the patients successfully corrected their foot inversion. The research team also utilised IoT technology to record patients’ rehabilitation progress via a mobile app. This approach, incorporating functions such as real-time monitoring and progressive evaluation, as well as personalised guidance and reminders, enables patients to effectively engage in rehabilitation training even without the physical presence of a therapist, thereby improving patient engagement and treatment outcomes. The rehabilitation progresses of multiple patients can be matched to each other via the app for fostering mutual support and companionship throughout their training journey. It also enables therapists to provide remote monitoring and supervision on the progress of multiple patients, ensuring that rehabilitation proceeds smoothly. Dr Hu’s research team plans to commercialise the Mobile Ankle-foot Exoneuromusculoskeleton next year. In 2021, she co-founded the startup Thecon Technology (HK) Limited, which has been supported by the Incu-Bio Programme of Hong Kong Science and Technology Parks. Last year, the startup successfully launched a mobile exoneuromusculoskeleton for upper limb rehabilitation, the “Mobilexo Arm”, onto the market. This product has been adopted by a number of local and Mainland hospitals and rehabilitation clinics.   ***END***

Healthy Ageing Conference 2023 Advancing Healthy Ageing in the Western Pacific Moving Forward with the UN Decade of Healthy Ageing

Population ageing is a pressing priority in the Western Pacific region, home to one of the world's largest and fastest-growing elderly populations. Recognizing the significance of this issue, the World Health Organization (WHO) has taken the lead in developing an action plan on healthy ageing for the region, aligned with the United Nations (UN) Decade of Healthy Ageing (2021–2030). In line with these efforts, the Healthy Ageing Conference 2023 was successfully held in Hong Kong on 26-27 October 2023. The conference, organized by the World Health Organization Collaborating Centre for Community Health Services, School of Nursing of The Hong Kong Polytechnic University (PolyU), and co-organized by the Department of Health of The Government of Hong Kong Special Administrative Region (HKSAR), PolyU Research Institute of Smart Ageing, and PolyU Department of Rehabilitation Sciences, served as a crucial platform to address the challenges and explore innovative solutions for healthy ageing in the region. The conference's opening ceremony marked its official commencement, with esteemed speakers delivering their addresses. Prof. Jin-Guang TENG, President of PolyU, welcomed participants and emphasized the pivotal role of the conference in realizing the United Nations' vision of healthy ageing. “The conference aimed to address the multifaceted factors influencing the well-being of older individuals and their families. It provided a platform to showcase cutting-edge gerontechnological innovations, discuss the latest interventions and advancements in epidemiology, and identify comprehensive strategies for implementing the WHO's action items.” Prof. TENG remarked. Mr ZHANG Hui, Counsellor (DG level) from the Department of Ageing and Health, National Health Commission of the People's Republic of China, emphasized healthy ageing was the least costly and most effective means and ways to cope with population ageing. The Chinese government had been positively responding to the United Nations Decade of Healthy Ageing (2021-2030). Mr. ZHANG highlighted the significance of collaboration and knowledge exchange between Mainland China, Hong Kong, and Macao in various aspects such as scientific research, technologies, projects, standards, norms, talents, services, and industries related to healthy ageing and elderly care. Mr ZHANG Hui expressed, "The National Health Commission will continue to strengthen exchanges and cooperation with Hong Kong and Macao in the field of healthy aging, learn from each other and complement each other's advantages." Prof. Chung-mau LO, Secretary of Health, Health Bureau of the HKSAR Government, emphasized that the government acknowledges the significant challenges posed by the rapidly ageing population. The government is committed to implementing a comprehensive structural reform that will transition the healthcare system from a treatment-oriented approach to a prevention-focused approach, and shift the service delivery from hospital-based to community-based settings.
