Design of EMG-driven Musculoskeletal Model for Volitional Control of a Robotic Ankle Prosthesis [PDF]

arXiv, 2022
Existing robotic lower-limb prostheses use autonomous control to address cyclic, locomotive tasks, but they are inadequate to operate the prosthesis for daily activities that are non-cyclic and unpredictable. To address this challenge, this study aims to design a novel electromyography (EMG)-driven musculoskeletal model for volitional control of a ...

Single‐Cell Analysis Clarifies Pathological Heterogeneity in Tenosynovial Giant Cell Tumor and Identifies Biomarkers for Predicting Disease Recurrence

Advanced Science, EarlyView.
MP3 tumor cells, a specific subpopulation of tumor cells in D‐TGCT, regulated the differentiation of CD34+ Fbs into MMP3+ Fbs and APOE+ Fbs through COL6A3 − (ITGAV + ITGB8) interaction. APOE+ Fbs activated IL‐1B+CCL20+ Mφs through the CXCL12/CXCR4 axis. IL‐1B+CCL20+ Mφs and MMP3+ Fbs participated in the local invasion of D‐TGCT.

A Multichannel RF Transceiver Array with mixed L-C loop and microstrip elements for Foot/Ankle MR Imaging at 7T [PDF]

arXiv, 2022
It is technically challenging to design efficient transceiver coil arrays for foot and ankle imaging at ultrahigh fields due to the irregular geometry of the anatomy. Shortened wavelength because of the high operation frequency at ultrahigh fields increases phase variation, leading to inhomogeneous B1 distribution in the imaging sample.

Expanding the phenotypic variability of MORC2 gene mutations: From Charcot‐Marie‐Tooth disease to late‐onset pure motor neuropathy

Human Mutation, Volume 43, Issue 12, Page 1898-1908, December 2022., 2022
Expanding the phenotypic variability of MORC2 gene mutations: From Charcot‐Marie‐Tooth disease to late‐onset pure motor neuropathy Abstract MORC2 gene encodes a ubiquitously expressed nuclear protein involved in chromatin remodeling, DNA repair, and transcriptional regulation. Heterozygous mutations in MORC2 gene have been associated with a spectrum of

Optimizing the Use of an Artificial Tongue-Placed Tactile Biofeedback for Improving Ankle Joint Position Sense in Humans [PDF]

28th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (2006) 6029-6032, 2006
The performance of an artificial tongue-placed tactile biofeedback device for improving ankle joint position sense was assessed in 12 young healthy adults using an active matching task. The underlying principle of this system consists of supplying individuals with supplementary information about the position of the matching ankle relative to the ...

Maximum-Entropy-Rate Selection of Features for Classifying Changes in Knee and Ankle Dynamics During Running [PDF]

IEEE Journal of Biomedical and Health Informatics, 22(4), 1097-1103, 2018
This paper investigates deteriorations in knee and ankle dynamics during running. Changes in lower limb accelerations are analyzed by a wearable musculo-skeletal monitoring system. The system employs a machine learning technique to classify joint stiffness. A maximum-entropyrate method is developed to select the most relevant features.

A unified perspective on ankle push-off in human walking

Journal of Experimental Biology, 2016
Muscle–tendon units about the ankle joint generate a burst of positive power during the step-to-step transition in human walking, termed ankle push-off, but there is no scientific consensus on its functional role.

Therapeutic Potential of Lipid Nanoparticle‐Encapsulated CD19‐Targeting mRNAs in Lupus and Rheumatoid Arthritis

Advanced Science, EarlyView.
This study develops lipid nanoparticle‐encapsulated mRNA‐encoding antibodies (mRNab‐LNPs) targeting CD19, demonstrating robust anti‐CD19 antibody production in vivo. Intramuscular injection of mRNab‐LNPs reduces CD19+ B and plasma cells in lupus and rheumatoid arthritis mice, significantly alleviating histopathological changes and tissue injuries of ...
