liver disease screening_01

Ir Professor Yongping Zheng's startup takes lead in implementing territory-wide large-scale liver disease screening programme ; As the first participating institution, PolyU drives translation of research into real-world applications

According to the “2024 Global Hepatitis Report” by the World Health Organization, the number of lives lost due to viral hepatitis is increasing year by year, leading to 1.3 million deaths in 2022, claiming 3,500 lives each day in average, and resulting in it constituting the second leading cause of infectious disease deaths worldwide 1. In response to this global public health issue, Eieling Technology Limited (Eieling Technology), an academic-led startup nurtured and supported by The Hong Kong Polytechnic University (PolyU), has announced its leadership in implementation of the five-year “LiverCare – Hong Kong 10 Million Liver Scans Program” (the Programme), to improve public awareness of liver disease prevention, and promote early detection and treatment to reduce the impact of liver disease. Prof. Christopher CHAO, Vice President (Research and Innovation) of PolyU and Ir Prof. ZHENG Yongping, Henry G. Leong Professor in Biomedical Engineering, Chair Professor of Biomedical Engineering and Director of the Research Institute of Smart Ageing of PolyU, joined by Mr Patrick LAU, Deputy Executive Director of the Hong Kong Trade Development Council; Prof. Walter SETO, Clinical Professor in Gastroenterology and Hepatology of the University of Hong Kong; Dr Grace LAU, Head of the Institute for Translational Research of the Hong Kong Science and Technology Parks Corporation (HKSTP); Mr Xiaojia JIA, Chief Executive Officer of Eieling Technology Limited; and Ms Mildred LAW of the Hong Kong Liver Foundation officiated at the Programme launch ceremony yesterday (16 May). PolyU has long been committed to translating its technologies into real-world applications. The University will support the Programme and become the first institution to conduct the Programme. Starting from July this year, PolyU will conduct liver fibrosis and fatty liver screening for full-time university staff using Liverscan®, a palm-size wireless ultrasound imaging device. Participants are also encouraged to join a two-year follow-up study. From the data collected, the research team will study the importance of a balanced diet and daily exercise, as well as regular liver disease screening for monitoring the progression of liver disease. PolyU believes that the programme can not only improve public awareness of liver disease prevention and promote early detection and treatment, but also help reduce the threat of liver disease to human health. Prof. Chao said, “As a PolyU-nurtured start-up, Eieling Technology actively commercialises the University’s patents. With the support from investors and industries through the innovation and entrepreneurship ecosystem of PolyU, the company is able to translate its technologies into products with a positive impact on society. The launch of the programme marks a milestone for PolyU in contributing to the global public health, reflecting the University's commitment to social responsibility and the translation of scientific research outcomes. In recent years, PolyU has strategically established technology innovation institutes in several cities in the Mainland China, aiming to combine PolyU's unique advantages in basic research and innovation with the robust industrial bases and characteristics of various regions in the Mainland. This initiative promotes research and transformation of core technologies, cultivates innovative talents with knowledge in technology and global vision, and provides a more optimised application platform and scenarios for enterprises. Through these measures, PolyU will continuously strengthen its cooperation with cities in Mainland China, promote regional economic development, and also provide a favorable environment for university researchers to apply theory to practice and commercialise research findings." Eieling Technology, co-founded by Prof. Zheng and his research team in 2018, is a technology development company specialising in advanced medical ultrasound imaging devices designed to screen for liver diseases. Prof. Zheng and his PolyU research team combined transient elastography diagnostic technology with a real-time ultrasound image guided system to develop a solution called Liverscan® for liver fibrosis assessment. Liverscan® is an innovative medical device which, since it is palm-sized, wireless, lightweight and portable, easy to control and economical, allows medical staff to perform liver checkups on patients anytime, anywhere. Prof. Zheng said, “Liver fibrosis can be caused by long-term inflammation of liver tissue, excessive alcohol intake or long-term fatty liver, and may develop into cirrhosis, liver dysfunction, or even liver cancer. We hope that through the ultrasound device Liverscan®, which can lower costs, shorten examination time, facilitate operation and improve measurement accuracy, liver disease assessment and screening will be widely available to people in the community, thereby reducing the number patients with severe liver disease in the coming years significantly.” Eieling Technology has been supported by the PolyU Tech Launchpad Fund and the Incu-Bio Programme of HKSTP, as well as by secured funding from several industrial partners and private investors. Liverscan® has obtained registration approval from the US Food and Drug Administration (FDA510K) and is being used in many well-known hospitals and clinics in Hong Kong, Macau and other places. Eieling Technology is also carrying out clinical research and cooperation with several hospitals in Mainland China. Liverscan® is expected to enter the market in Mainland China after receiving registration approval from the National Medical Products Administration in Q3 this year, and to be launched globally in 2025.   1World Health Organization- “Global hepatitis report 2024”

49th Geneva_v3_01

PolyU BME Teams snatch awards at 49th International Exhibition of Inventions Geneva

Impactful innovations from The Hong Kong Polytechnic University (PolyU) won a record-breaking number of accolades at the 49th International Exhibition of Inventions Geneva (Geneva Inventions Expo), a widely recognised annual event devoted exclusively to invention. 43 PolyU innovations seized 45 accolades, including two Special Prizes, five Gold Medals with Congratulations of the Jury, 18 Gold Medals, 13 Silver Medalsand seven Bronze Medals. Among them, two were developed by PolyU BME’s research teams. PolyU BME’s project “ProRuka — Novel Prosthetic Hand Controlled by Wireless Sonomyography” won the “Gold Medal with Congratulations of the Jury” and the “Special Award from Taiwan Invention Association”. The project is co-led by Ir Prof. Yongping ZHENG, Henry G. Leong Professor in Biomedical Engineering and Chair Professor of PolyU BME, and Mr Vaheh NAZARI, Research Assistant, PolyU BME. ProRuka is a novel 3D printed prosthetic powered hand that can move its fingers independently. It is controlled by stump muscle signals collected by wireless wearable ultrasound imaging known as sonomyography. These signals are analysed by AI algorithms in real-time to decode the natural control mechanism of a human hand. The AI model can also classify a specific hand gesture and the degree of action, based on the activation pattern of all muscles combined in the scanning area. ProRuka allows more intuitive control of the prosthetic hand and can predict more complex hand gestures with higher accuracy. The mechanical design is based on the natural dimensions and proportions of the human hand and is lightweight and cost-effective. ProRuka aims to improve the comfort and acceptance of prosthetic hand users, and help them regain quality of life, independence and confidence. The “Mobile Ankle-foot Exoneuromusculoskeleton” developed by the research team led by Dr Xiaoling HU, Associate Professor of BME and Founder of Thecon Technology HK Ltd. (a PolyU academic-led startup), won the Gold Medal. The mobile ankle-foot exoneuromusculoskeleton is the first device of its kind to combine the advantages of exoskeletons, soft pneumatic muscles, neuromuscular electrical stimulation and tactile sensory feedback into a single, lightweight wearable system powered by a small rechargeable battery. This unique combination can effectively correct poststroke footdrop and foot inversion, which are common issues faced by stroke survivors. It is also easy to use by non-professionals for self-help telerehabilitation. The device is connected to the Internet of Things, which allows it to connect professionals and multiple poststroke users in different locations. This enables the efficient management of rehabilitation and motivates users to continue their training through incentive schemes, which, in turn, enhances the efficiency and effectiveness of rehabilitation and reduces the burden on professionals. By enabling remote and self-help telerehabilitation, it can also provide quality care to more stroke survivors who need it. Prof. Christopher CHAO, PolyU Vice President (Research and Innovation), extended his congratulations to the University’s winning teams and stated, “I am thrilled about the exceptional accomplishments of PolyU’s research teams at the Geneva Inventions Expo this year. The results are truly encouraging and serve as a testament to the outstanding research capabilities of our scholars and experts. The international recognition will inspire them to continue pursuing excellence, not only in basic research but also in translating their research outcomes into positive impacts for the benefit of Hong Kong, our Nation, and the world.”

Lei_nature communication_PNAS_1

Professor Lei Sun’s researches published in Nature Communications and PNAS

The research papers of Professor Lei Sun have been published in the world-renowned scientific journals Nature Communications and Proceedings of the National Academy of Sciences of the United States of America (PNAS) respectively. Below are the details of these outstanding researches:   “Nanobubble-actuated ultrasound neuromodulation for selectively shaping behavior in mice” Xuandi Hou, Jianing Jing, Yizhou Jiang, Xiaohui Huang, Quanxiang Xian, Ting Lei, Jiejun Zhu, Kin Fung Wong, Xinyi Zhao, Min Su, Danni Li, Langzhou Liu, Zhihai Qiu & Lei Sun Nature Communications 15, Article number: 2253 (2024) Abstract Ultrasound is an acoustic wave which can noninvasively penetrate the skull to deep brain regions, enabling neuromodulation. However, conventional ultrasound’s spatial resolution is diffraction-limited and low-precision. Here, we report acoustic nanobubble-mediated ultrasound stimulation capable of localizing ultrasound’s effects to only the desired brain region in male mice. By varying the delivery site of nanobubbles, ultrasound could activate specific regions of the mouse motor cortex, evoking EMG signaling and limb movement, and could also, separately, activate one of two nearby deep brain regions to elicit distinct behaviors (freezing or rotation). Sonicated neurons displayed reversible, low-latency calcium responses and increased c-Fos expression in the sub-millimeter-scale region with nanobubbles present. Ultrasound stimulation of the relevant region also modified depression-like behavior in a mouse model. We also provide evidence of a role for mechanosensitive ion channels. Altogether, our treatment scheme allows spatially-targetable, repeatable and temporally-precise activation of deep brain circuits for neuromodulation without needing genetic modification.     “Modulation of deep neural circuits with sonogenetics” Quanxiang Xian, Zhihai Qiu, Suresh Murugappan, Shashwati Kala, Kin Fung Wong, Danni Li, Guofeng Li, Yizhou Jiang, Yong Wu, Min Su, Xuandi Hou, Jiejun Zhu, Jinghui Guo, Weibao Qiu, and Lei Sun Proceedings of the National Academy of Sciences, May 2023 Abstract Noninvasive control of neuronal activity in the deep brain can be illuminating for probing brain function and treating dysfunctions. Here, we present a sonogenetic approach for controlling distinct mouse behavior with circuit specificity and subsecond temporal resolution. Targeted neurons in subcortical regions were made to express a mutant large conductance mechanosensitive ion channel (MscL-G22S), enabling ultrasound to trigger activity in MscL-expressing neurons in the dorsal striatum and increase locomotion in freely moving mice. Ultrasound stimulation of MscL-expressing neurons in the ventral tegmental area could activate the mesolimbic pathway to trigger dopamine release in the nucleus accumbens and modulate appetitive conditioning. Moreover, sonogenetic stimulation of the subthalamic nuclei of Parkinson’s disease model mice improved their motor coordination and mobile time. Neuronal responses to ultrasound pulse trains were rapid, reversible, and repeatable. We also confirmed that the MscL-G22S mutant is more effective to sensitize neurons to ultrasound compared to the wild-type MscL. Altogether, we lay out a sonogenetic approach which can selectively manipulate targeted cells to activate defined neural pathways, affect specific behaviors, and relieve symptoms of neurodegenerative disease.     “The mechanosensitive ion channel Piezo1 contributes to ultrasound neuromodulation” Jiejun Zhu, Quanxiang Xian, Xuandi Hou, Kin Fung Wong, Tingting Zhu, Zihao Chen, Dongming He, Shashwati Kala, Suresh Murugappan, Jianing Jing, Yong Wu, Xinyi Zhao, Danni Li, Jinghui Guo, Zhihai Qiu, and Lei Sun Proceedings of the National Academy of Sciences, April 2023 Abstract Transcranial low-intensity ultrasound is a promising neuromodulation modality, with the advantages of noninvasiveness, deep penetration, and high spatiotemporal accuracy. However, the underlying biological mechanism of ultrasonic neuromodulation remains unclear, hindering the development of efficacious treatments. Here, the well-known Piezo1 was studied through a conditional knockout mouse model as a major mediator for ultrasound neuromodulation ex vivo and in vivo. We showed that Piezo1 knockout (P1KO) in the right motor cortex of mice significantly reduced ultrasound-induced neuronal calcium responses, limb movement, and muscle electromyogram (EMG) responses. We also detected higher Piezo1 expression in the central amygdala (CEA), which was found to be more sensitive to ultrasound stimulation than the cortex was. Knocking out the Piezo1 in CEA neurons showed a significant reduction of response under ultrasound stimulation, while knocking out astrocytic Piezo1 showed no-obvious changes in neuronal responses. Additionally, we excluded an auditory confound by monitoring auditory cortical activation and using smooth waveform ultrasound with randomized parameters to stimulate P1KO ipsilateral and contralateral regions of the same brain and recording evoked movement in the corresponding limb. Thus, we demonstrate that Piezo1 is functionally expressed in different brain regions and that it is an important mediator of ultrasound neuromodulation in the brain, laying the ground for further mechanistic studies of ultrasound.

Dr Puxiang Lai’s research on “High-security learning-based optical encryption assisted by disordered metasurface” published in Nature Communications

The research paper titled “High-security learning-based optical encryption assisted by disordered metasurface”, with Associate Professor Dr Puxiang Lai as one of the co-authors, is published in Nature Communications, an open access, multidisciplinary journal dedicated to publishing high-quality research in all areas of the biological, health, physical, chemical, Earth, social, mathematical, applied, and engineering sciences.    “High-security learning-based optical encryption assisted by disordered metasurface” Zhipeng Yu, Huanhao Li, Wannian Zhao, Po-Sheng Huang, Yu-Tsung Lin, Jing Yao, Wenzhao Li, Qi Zhao, Pin Chieh Wu, Bo Li, Patrice Genevet, Qinghua Song & Puxiang Lai Nature Communications volume 15, Article number: 2607 (2024). doi: 10.1038/s41467-024-46946-w Abstract Artificial intelligence has gained significant attention for exploiting optical scattering for optical encryption. Conventional scattering media are inevitably influenced by instability or perturbations, and hence unsuitable for long-term scenarios. Additionally, the plaintext can be easily compromised due to the single channel within the medium and one-to-one mapping between input and output. To mitigate these issues, a stable spin-multiplexing disordered metasurface (DM) with numerous polarized transmission channels serves as the scattering medium, and a double-secure procedure with superposition of plaintext and security key achieves two-to-one mapping between input and output. In attack analysis, when the ciphertext, security key, and incident polarization are all correct, the plaintext can be decrypted. This system demonstrates excellent decryption efficiency over extended periods in noisy environments. The DM, functioning as an ultra-stable and active speckle generator, coupled with the double-secure approach, creates a highly secure speckle-based cryptosystem with immense potentials for practical applications.   Conceptional diagram of the proposed optical encryption system. a Optical encryption. The sender (Alice) illuminates light beams with two different polarizations of P(i) and P(j) onto the phase profiles of the superposition of plaintexts (human face images) and security keys (QR codes), which propagates through DM, generating ciphertexts (speckles). b Learning-based decryption. Two deep neural networks (DNN) of the same structure, e.g., P(i)-DMNet and P(j)-DMNet, are trained with data obtained with incident beams of P(i) and P(j), respectively. After recording the ciphertext and being authorized by Alice to acquire the security key and the polarization of the incident beam, the receiver (Bob) can feed the ciphertext and the security key into the corresponding neural network to decrypt the plaintext. The mark “×” above the straight line with arrows at both ends indicates that the information cannot be commutative. DM disordered metasurface.
