RISThe Relationship Between Sperm Velocity and Pressures Applied to the Zona Pellucida During Early Sperm-Oocyte Penetration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sperm velocity is long known to be an important indicator of sperm quality but without much biophysical theory explaining it. Contact mechanics based modeling was developed here to determine ...
Effects of Virus Size and Cell Stiffness on Forces, Work, and Pressures Driving Membrane Invagination in a Receptor-Mediated Endocytosis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A continuum model based on the contact mechanics theory was developed and used for evaluating virus indentation forces at the early stage of membrane invagination, as well as the work of the ...
Stretching Affects Intracellular Oxygen Levels: Three-Dimensional Multiphysics Studies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multiphysics modeling is an emerging approach in cellular bioengineering research, used for simulating complex biophysical interactions and their effects on cell viability and function. Our goal ...
Viscoelastic Properties of Ovine Adipose Tissue Covering the Gluteus Muscles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pressure-related deep tissue injury (DTI) is a life-risking form of pressure ulcers threatening immobilized and neurologically impaired patients. In DTI, necrosis of muscle and enveloping adipose ...
Cell-to-Cell Variability in Deformations Across Compressed Myoblasts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Many biological consequences of external mechanical loads applied to cells depend on localized cell deformations rather than on average whole-cell-body deformations. Such localized intracellular ...
Stress Analyses Coupled With Damage Laws to Determine Biomechanical Risk Factors for Deep Tissue Injury During Sitting
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Deep tissue injury (DTI) is a potentially life-threatening form of pressure ulcer that onsets in muscle tissue overlying bony prominences and progresses unnoticeably to more superficial tissues. ...
Measurements of the Static Friction Coefficient Between Bone and Muscle Tissues
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study aimed at measuring the static coefficient of friction (μ) between bone and skeletal muscle tissues in order to support finite element (FE) modeling in orthopaedic and rehabilitation ...
The Diabetic Foot Load Monitor: A Portable Device for Real-Time Subject-Specific Measurements of Deep Plantar Tissue Stresses During Gait
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Elevated stresses in deep plantar tissue of diabetic neuropathic patients were associated with an increased risk for foot ulceration, but only interfacial foot pressures are currently measured ...
A New System for Monitoring Gait Training in Infants With Down Syndrome
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Infants with Down syndrome show an altered pattern of motor development at early childhood. Treadmill-walking training can be used to promote the earlier attainment of motor milestones in infants ...
Effects of Intramuscular Fat Infiltration, Scarring, and Spasticity on the Risk for Sitting-Acquired Deep Tissue Injury in Spinal Cord Injury Patients
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sitting-acquired deep tissue injury (DTI) is a severe form of pressure ulcer (PU) often affecting patients with spinal cord injury (SCI) who also tend to suffer from intramuscular fat infiltration, ...
