Characterizing Engineered Skeletal Muscle Rings as Actuators Using Strain Sensing Methods
A novel instrument was designed to characterize a force exertion model of engineered skeletal muscle rings. The instrument uses strain gauges to transduce a muscle ring contraction and has a verified resolution of 5 μN and 1.4 μm over the ranges of 5 μN and 1400 μm respectively. Experiments were …

Biomechanical analysis of carpal flexion and extension
… wrist position, and direction of motion or exertion were evaluated to determine their effects on instant center of rotation (ICOR) and the magnitude of force exertion. The knowledge gained from analysis of the study data will be the first step in the formulation of a biomechanical model of …

INTERRELATIONSHIP BETWEEN CONTRACTILITY AND DYNAMICS OF ACTOMYOSIN SYSTEM IN NON-MUSCLE CELLS
… end, I manipulated either actin incorporation or forces to investigate their effects. Surprisingly, SMIFH2 strongly inhibited the force exertion. I hence proposed that formins could physically link actin filaments with each other, thus participating in force transmission processes. On the other …

Interactions of Fibroblast with Cytotoxic and Invasive Strains of Pseudomonas aeruginosa on ECM Mimicking Fibers
… fibroblast morphology, migratory behavior, and force exertion to investigate this host cell's response to representative cytotoxic (PAO1) and invasive (PA14) strains of P. aeruginosa. These assays study host cell-pathogen interactions on highly aligned nanofibers of varied spacing and diameter, …

Stability of the Shoulder Complex during Manual Exertions
… Epidemiological literature suggests that forceful arm exertions pose an increased risk for shoulder MSD development. Although several previous studies have reported a significant stress-strain relationship for the shoulder complex during physically demanding exertions, a clear assessment …

Adaptive, Anthropomorphic Robot Hands for Grasping and In-Hand Manipulation
… modes with the finger motion and the tendon force with the finger characteristics. For the hand design, the use of differential mechanisms simplifies the actuation scheme, as we utilize only two actuators for four fingers, achieving affordable dexterity. A design optimization framework assess …

Development of Simulation Platform for Oropharyngeal Airway Placement and Design Evaluation of the Bardo Airway
… a bite-block, and the subsequential procedure of force exertion of the device by physician has caused many cases of patient’s teeth damage and monetary loss, as the patient’s incisors were damaged while clenching on the OPA during an adverse scenario called “Emergency Clenching”. To remedy this …

Cytotoxic T lymphocyte biology under the microscope
… Chapter 3 introduces biophysics and the idea of forces at the cellular level. These play an important and emerging role in CTL function, highlighted by the fact that high-affinity molecular interactions between pMHC and TCR are not sufficient to drive T cell activation if the surface presenting …

Veranschaulichung subzellulärer physikalischer Kräfte biochemischen und mechanischen Ursprungs mittels FRET
Das zelluläre Cytoskelett besteht aus Mikrofilamenten, intermediären Filamenten, Mikrotubuli und einer Reihe von weiteren Proteinen, die seine von dem Zelltyp und von der Zellumgebung abhängige Dynamik kontrollieren. Proteine, die der Rho GTPase Familie angehören, spielen hierbei eine wichtige …
