Central retinal vessels (CRVs) oriented asymmetrically in the ONH are the single blood supply source to the retina and are believed to act as mechanically stable elements in the ONH in response to intraocular pressure (IOP). However, these mechanical effects are considered negligible in ONH biomechanical studies and received less attention. This study investigated the effects of CRVs on ONH biomechanics taking into consideration three-dimensional asymmetric CRV geometries. A CRV geometry was constructed based on CRV centerlines extracted from optical coherence tomography ONH images in eight healthy subjects and superimposed in the idealized ONH geometry established in previous studies. Mechanical analyses of the ONH in response to the IOP were conducted in the cases with and without CRVs for comparison. Obtained results demonstrated that the CRVs induced anisotropic ONH deformation, particularly in the lamina cribrosa and the associated upper neural tissues (prelamina) with wide ranges of spatial strain distributions. These results indicated that the CRVs result in anisotropic deformation with local strain concentration, rather than function to mechanically support in response to the IOP as in the conventional thinking in ophthalmology.}, keywords = {glaucoma; optical coherence tomography; smoothed finite element method; Central retinal vessel; Optic nerves head}, year = {2024}, eissn = {1873-4030}, orcid-numbers = {Otani, Tomohiro/0000-0002-6431-2703} } @article{MTMT:34496611, title = {Design and fabrication of a novel 4D-printed customized hand orthosis to treat cerebral palsy}, url = {https://m2.mtmt.hu/api/publication/34496611}, author = {Barmouz, M. and Uribe, L.V. and Ai, Q. and Azarhoushang, B.}, doi = {10.1016/j.medengphy.2023.104087}, journal-iso = {MED ENG PHYS}, journal = {MEDICAL ENGINEERING & PHYSICS}, volume = {123}, unique-id = {34496611}, issn = {1350-4533}, year = {2024}, eissn = {1873-4030} } @article{MTMT:34640028, title = {A fast permutation entropy for pulse rate variability online analysis with one-sample recursion}, url = {https://m2.mtmt.hu/api/publication/34640028}, author = {Zhan, Jianan and Gan, Zhengli and Chou, Lijuan and Hu, Linqi and Zhou, Yan and Yang, Haiping and Chou, Yongxin}, doi = {10.1016/j.medengphy.2023.104050}, journal-iso = {MED ENG PHYS}, journal = {MEDICAL ENGINEERING & PHYSICS}, volume = {120}, unique-id = {34640028}, issn = {1350-4533}, keywords = {Permutation entropy; Online processing; pulse rate variability; Portable wearable devices; Pulsation signal}, year = {2023}, eissn = {1873-4030} } @article{MTMT:34366743, title = {Mechanical and biodegradability of porous PCL/PEG copolymer-reinforced cellulose nanofibers for soft tissue engineering applications}, url = {https://m2.mtmt.hu/api/publication/34366743}, author = {Abu Ghalia, Mustafa and Alhanish, Atika}, doi = {10.1016/j.medengphy.2023.104055}, journal-iso = {MED ENG PHYS}, journal = {MEDICAL ENGINEERING & PHYSICS}, volume = {120}, unique-id = {34366743}, issn = {1350-4533}, abstract = {The design and development of a new class of biomaterial has gained particular interest in producing polymer scaffold for biomedical applications. Mechanical properties, biological and controlling pores scaffold of the biomaterials are important factors to encourage cell growth and eventual tissue repair and regeneration. In this study, poly-epsilon-caprolactone (PCL) /polyethylene glycol (PEG) copolymer (80/20) incorporated with CNF scaffolds were made employing solvent casting and particulate leaching methods. Four mass percentages of CNF (1, 2.5, 5, and 10 wt.%) were integrated into the copolymer through a silane coupling agent. Mechanical properties were determined using Tensile Tester data acquisition to investigate the effect of porosity, pore size, and CNF contents. Tensile strength obtained for PCL/PEG- 5 wt.% CNF was 16 MPa, which drastically decreased after creating a porous structure to 7.1 MPa. The optimum parameters of the results were found to be 5 wt.% for CNF, 240 mu m for pore size, and 83% for porosity. Scanning electron microscopy (SEM) micrograph reveals that consistent pore size and regular pore shape were accomplished after the addition of CNF-5 wt.% into PCL/PEG. The results of mass loss of PCL/PEG reinforced-CNF 1 % have clearly enhanced to double values compared with PCL/PEG copolymer and three times with PCL/PEG scaffold-CNF 1 %. In addition, all PCL/PEG reinforced and scaffoldCNF were partially disintegrated under composting conditions confirming their biodegradable behavior. This also provides a possible solution for the end life of these biomaterials.}, keywords = {BIODEGRADATION; Tissue Engineering; cellulose nanofibers; PCL/PEG; Compost polymers}, year = {2023}, eissn = {1873-4030} } @article{MTMT:34347576, title = {Analysis and multiple index evaluation of SPO distribution of bone traction needles for pelvic fracture reduction}, url = {https://m2.mtmt.hu/api/publication/34347576}, author = {Wei, Yimin and Lei, Jingtao and Hu, Lei and Zhang, Lihai}, doi = {10.1016/j.medengphy.2023.104031}, journal-iso = {MED ENG PHYS}, journal = {MEDICAL ENGINEERING & PHYSICS}, volume = {119}, unique-id = {34347576}, issn = {1350-4533}, abstract = {For robot-assisted pelvic fracture reduction, at least two bone needles need to be inserted into the ilium of the affected pelvis, and the robot clamping device is connected with the bone needles.

In order to determine the optimal SPO of bone needle pairs, the constraints between the bone needles and the pelvis are analyzed, and the SPO vectors of 150 groups bone needles are obtained by the KNNhierarchical clustering method; a batch modeling method of bone needles with different SPO is proposed. 150 finite element models of damaged pelvic musculoskeletal tissue with different SPO of bone needles are established and simulated. The stress and strain distribution homogenization of musculoskeletal tissue with bone needles as evaluation index, the simulation results of 150 models are evaluated. Results show that, the anterior superior iliac spine and the anterior inferior iliac spine are suitable regions to place bone needles in the pelvis, and the optimal distribution of the needle combination is found in this region.
