In recent years, due to industrialization, injury rates in developing countries, notably road traffic injuries (RTIs), have drastically increased. This has led to many fracture patients in ill- equipped countries, such as Kenya with only 60 orthopedic surgeons for a population of 36.9 million, not having any rigorous rehabilitation protocol or quality postoperative care. This work focuses on the development of a telemetric gait analysis insole that works in conjunction with a mobile application and convolutional neural network. This technique automates the tedious process of tracking postoperative fracture rehabilitation by analyzing ground reaction forces (GRFs) of patients which correlate well with weight-bearing ability, fracture healing, and delayed union. 4 force-sensitive resistors (FSRs) are placed in the insole under the primary areas for force measurement. An Arduino microcontroller compiles the data and sends it to a Python program via a Bluetooth module. The Python program performs peak analysis on the data to determine the average peak Vertical Ground Reaction Force (VGRF) of the strides to measure if a patient is properly healing. As a further step, we employ a 1D-CNN to differentiate between healed and healing patients to automatically find which patients have nonunions. With these methodologies we are able to automatically diagnose rural patients with nonunions based on only ground reaction force measurements at minimal costs and without an on-site physician.","PeriodicalId":274908,"journal":{"name":"2021 IEEE 3rd Global Conference on Life Sciences and Technologies (LifeTech)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134468686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While studies on organoids for osteocyte-related model have not yet been reported, the osteocyte plays a role as a control tower to regulate the bone remodeling by controlling osteoclasts and osteoblasts. In this study, we fabricated 3D self-organized spheroids reconstructed by mouse osteoblast precursor cells (MC3T3-E1) as well as human bone marrow derived mesenchymal stem cells (MSC), and further investigated their osteocyte differentiation capability. As a result of real-time PCR and immunostaining, the spheroid culture greatly up-regulated osteocyte markers in a short period of time, 2 days, compared to the conventional two-dimensional (2D) monolayer model. Consequently, the results altogether suggest that the 3D culture technology using the self-organized spheroids rendered the osteocyte-likeness and further is expected to become a new in vitro model to represent the osteocytes.","PeriodicalId":274908,"journal":{"name":"2021 IEEE 3rd Global Conference on Life Sciences and Technologies (LifeTech)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115227518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such fluctuation, referred to as the gait cycle variability, is often quantified by measuring stride intervals, i.e., time intervals between one and the subsequent heel contacts of one of the feet. It has been known that gait cycle variability in healthy young people exhibits a positive persistency, which tends to be lost by aging and neurological diseases, including Parkinson's disease, suggesting that the positive persistency reflects endogenous stability of gait. We have reported previously that the degree of positive persistency decreased during distracted walking with smartphone-gaming induced cognitive load. Here, we hypothesized that the decrease in the positive persistency is caused by a change in the neural activity at supra-spinal level. To find evidence for this hypothesis, we measured electroencephalography (EEG) during walking with and without the cognitive load. As a result, though preliminary, amplitude of the EEG at gamma band increased at a timing prior to every heel contact in the cognitive load condition compared to the control condition. This preliminary result suggests that a supra-spinal gait control mechanism is involved in the gait cycle variability.","PeriodicalId":274908,"journal":{"name":"2021 IEEE 3rd Global Conference on Life Sciences and Technologies (LifeTech)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126140291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this project, a foot prosthesis was designed for improving the quality of life of a Ramphastos tucanus specimen that presents an amputation at tarsometatarsus level. The main objective is recovering its statics biomechanics through the design and implementation of a prosthetic prototype based on a kinetic analysis. Using the incremental prototypes methodology, the biological system requirements were identified, the technical features were analysed, the prototype was designed by selecting one of three alternatives proposed and analysed by computational methods and then the device was constructed and implemented. Currently is being evaluated. Thanks to the application of an ethogram, it was identified rest as the static position to evaluate in the biomechanical analysis; the adjustment and implementation of a force sensor evidenced an overload on the pelvic limb with the amputation by supporting the 62,3% of the mass of the bird; the biometrics define the prototype size and showed an increase of musculoskeletal mass on the gripped limb; besides, the kinetics study exposed the difference of the force applied by the flexor tendon on surfaces. The design was created using CAD tools, and applying materials as PET-G, stainless steel, and aluminium. The finite element analysis was carried out before implementing the prototype. This process extends to an ongoing adaptation and evaluation protocol designed specifically for the bird, allowing to identify the impact of the prototype over the animal in the different aspects named previously.","PeriodicalId":274908,"journal":{"name":"2021 IEEE 3rd Global Conference on Life Sciences and Technologies (LifeTech)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126511174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
