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 research project on climate-resilient coastal infrastructure supported by French National Research Agency/RGC Joint Research Scheme

Climate change is one of the most pressing issues facing the world. The Hong Kong Polytechnic University (PolyU) has received support from The French National Research Agency (Agence Nationale de la Recherche)/Research Grants Council Joint Research Scheme (ANR/RGC Joint Research Scheme) - 2023/24 Exercise to conduct an innovative project on enhancing the resilience of coastal infrastructure to mitigate climate change risks such as sea-level rise and storm surges. It is one of three projects awarded funding from among Hong Kong institutions. Global warming is seen to be leading to more frequent occurrences of extreme weather. In the face of this challenge, the project “Smart and Flexible Climate Change Adaptation of Coastal Infrastructure”, led by Dr You DONG , Associate Professor of Department of Civil and Environmental Engineering of PolyU, has been granted HK$2.45 million under the ANR/RGC Joint Research Scheme for a period of 48 months. The project is being undertaken in collaboration with Prof. Edgar Emilio Bastidas Arteaga of La Rochelle University in France. Prof. Christina WONG, PolyU Director of Research and Innovation, said, “As an innovative world-class university excelling in diverse disciplines, PolyU has established extensive global partnerships for academic and research collaboration. With a mission to address complex global issues and tackle scientific challenges, we will continue to work closely with our partners to leverage our research strengths, drive innovation across a broad spectrum of cutting-edge research initiatives, and achieve a lasting global impact.” The funded project will focus on robust and intelligent adaptation of high-risk coastal building structures in Hong Kong and France to withstand compounded coastal flooding and sea level rise caused by global warming, storm surges resulting from tropical cyclones, and heavy rainfall. The intensity and frequency of these events are expected to increase due to climate change. A physics-informed data-driven approach is proposed to predict the occurrence and intensity of future flood hazards. Fluid-structure-interaction models will be developed to explore flood-related damage and failure mechanisms of coastal buildings in a life-cycle context. In addition, physics-guided deep learning will be utilised to develop multivariate vulnerability and risk models that focus on different building archetypes in the area under investigation and to form a framework for community-level vulnerability and resilience assessment. The research results are expected to generate technologies and knowledge that will contribute to the upgrading of climate-resilient infrastructure in Hong Kong and globally in the near-future. The ANR/RGC Joint Research Scheme aims to strengthen collaboration between French and Hong Kong research communities, and both basic and applied research proposals of high academic merit in all areas are invited under the Scheme. The assessment criteria include technical and scientific quality, quality of project management and methodology, global impact and the quality of synergies between the partners.   ***END***
