The first MOOC about Interdisciplinary Innovations for Population Ageing

Population ageing is a global phenomenon profoundly affecting the well-being of communities. Social sciences, design, and engineering each offers unique, insightful innovations for ageing societies. In response to rapidly ageing populations, this course intends to equip learners with age-friendly mindsets and capacities to fulfill the burgeoning demand for tailored, innovative policy, products, and services for older adults. The design of this course has been inspired by the belief that we should move beyond a uni-disciplinary, problem-oriented approach with the burden view when addressing ageing issues to adopt a more multidisciplinary, opportunity-oriented approach which emphasises on mobilising learners as asset for active ageing promotion.

27th Graduation Ceremony

COVID-19 testing device exhibited in the Central Market (Tangible Stories/Form follows Innovation) from 23 Oct 2021 to 9 Jan 2022

Dr. LEE Ming Hung Thomas (BME) and Prof. YIP Shea Ping (HTI) started developing gold nanoparticle-based colorimetric loop-mediated isothermal amplification (LAMP) assay for simple, fast, sensitive, specific, and inexpensive nucleic acid testing in 2014. The first-generation assay platform utilized disposable hand warmer content for LAMP reaction temperature control. In 2017, there were 2 major advancements, including new gold nanoparticle-based sensing method as well as simple and low-cost prototype device for real-time monitoring (device built by an undergraduate student). Since then, they collaborated with the Agriculture, Fisheries and Conservation Department's Veterinary Laboratory Division for avian influenza virus detection (device built by the Industrial Centre at PolyU). Starting in 2020 with the financial support by the Health and Medical Research Fund, the project team (with new members of Dr. SIU Kit Hang Gilman and Dr. HUANG Chien Ling at PolyU, Dr. FUNG Sau Chun Kitty at United Christian Hospital, Dr. LAM Yiu Wing Jimmy at Pamela Youde Nethersole Eastern Hospital, and Dr. JONG Kwok Kwan at Department of Health) has been using the assay platform for COVID-19 testing. The goal is to achieve rapid COVID-19 screening in decentralized settings such as airports, quarantine centers/hotels, and private clinics.

PolyU develops groundbreaking targeted osteoarthritis pain reliever

Researchers at PolyU introduced their development of an imaging-guided nanoparticle photothermal treatment for osteoarthritis pain that uses the concept of targeted cancer therapy in a press conference held yesterday (14 September). The targeted osteoarthritis pain theranostics, which offer both diagnostics and therapeutics, are made of gold nanorods which are fused with antibodies directed against the nerve growth factor (NGF), the pain-triggering protein.   Professor Yang Mo, Associate Head (Research) of the Department of Biomedical Engineering, said it is the first time the concept of targeted photothermal therapy for osteoarthritis pain via nanotechnology is being introduced. He said testing on mice suggests the targeted photothermal treatment achieves satisfactory pain relief and improvement of motor function. It holds good promise for clinical translation to achieve long-lasting pain relief for days.   Dr Wen Chunyi, Associate Professor of the Department of Biomedical Engineering, said the dual-track pain treatments with the antibody-fused nanorods and laser stimulation reduced the amount of NGF in joint tissues more efficiently and did not cause damage to the surrounding soft tissues or bone.    The research findings have been published in the prestigious journal ACS Nano by the American Chemical Society and were reported by Nature Reviews Rheumatology.  Press release: English - https://polyu.me/3hA6ggG; Chinese - https://polyu.me/3CckkVr   Online coverage: Sing Tao Daily - https://polyu.me/3AdzqJM Headline Daily - https://polyu.me/2Xg21iT Hong Kong Economic Times - https://polyu.me/399PEHM Ta Kung Pao - https://polyu.me/397R8T0 Hong Kong Economic Journal - https://polyu.me/39mttOZ Sky Post - https://polyu.me/2YM8XVF The Standard - https://polyu.me/3ljM8QS HK01 - https://polyu.me/3Aov6Hq Urban Life Health - https://polyu.me/3C9QJMk Bastille Post - https://polyu.me/3nvR6wH Line Today - https://today.line.me/hk/article/akN2KG MSN HK - https://polyu.me/2YMcOC7 PR Newsire - https://polyu.me/3ls6p6K

Ir Prof. Yongping Zheng invents Liverscan : a portable non-invasive system for liver fibrosis assessment

Alcohol abuse and hepatic tissue scarring due to long-term inflammation may cause liver fibrosis. In severe cases, liver fibrosis may develop into serious problems like liver cirrhosis, dysfunction and cancer. In recent years, transient elastography (TE) diagnostic technology has emerged as a non-invasive method to assess liver fibrosis by measuring the stiffness of the liver, but it has the disadvantages of high cost and insufficient accuracy. In view of this, Ir Professor Zheng Yong-ping, Department of Biomedical Engineering of The Hong Kong Polytechnic University has led a research team to develop Liverscan, a palm-sized wireless device that combines TE with a real-time ultrasound image guided system, substantially bringing down the cost and greatly enhancing the accuracy of measurement through the real-time imaging. Its lightweight and portable design allows medical staff to perform liver fibrosis detection for patients anytime, anywhere.

PolyU develops AI-based screening system for Knee Osteoarthritis

Knee Osteoarthritis (KOA) is a chronic degenerative disease with no cure. Early detection is critical for early intervention to prevent disease progression and to reduce the need for salvage joint replacement surgery.   A team led by Dr Chunyi Wen, Associate Professor of PolyU’s Department of Biomedical Engineering, has developed an artificial intelligence-based KOA screening system that can predict the risk of KOA progression at different time points in the future with an accuracy of 80%. The system won “Global Innovation Awards” at the TechConnect Business Virtual Summit and Showcase 2020.   The system was trained by US Dataset with data of over 10,000 KOA patients. Mr Justin Chan, MPhil student in Biomedical Engineering at PolyU, said the system can predict the risk of KOA with basic information of the patient, such as age and daily habit, plus a medical-related questionnaire of about 20 questions responded by the patient’s family doctor.   Dr Wen noted that under the current hospital flow, new KOA patients have to wait for years for treatment in public hospitals. Their system can provide early diagnosis and therefore reduce the consultation time by up to 90%. The outcome would also aid clinical practitioners to perform efficient triage and construct personalised treatment plans.   Mr Toby Li, also MPhil student in Biomedical Engineering at PolyU, pointed out that the AI system can deepen the collaboration between community medical and clinical systems, as well as improve the management of chronic diseases, and hence an expected reduction of health costs of HK$1.4 billion each year.   The team is currently applying to the Hospital Authority for the use of data of 100,000 KOA patients in Hong Kong, with an aim of enhancing the system’s accuracy to 90%. It is also applying for subsidies from the government to recruit 2,000 people for clinical tests within five years.   Moreover, a mobile application is being developed to measure and record relevant physiological data of the patients regularly, so as to facilitate continuous tracking and self-management of the disease.
