Background: The purpose of this study was to compare the brake reaction time of patients with successful right ankle fusion to normal volunteers without an ankle fusion.
Methods: Ten patients who underwent successful right ankle arthrodesis were evaluated using a driving simulator as well as an in-shoe pedobarographic measuring system. Brake reaction time, braking force, peak pressure, contact area, and the center of force between the foot and the brake pedal were recorded. SF-12 scores were obtained from all study patients. A control group of ten age-matched individuals without ankle fusion was included for comparison.
Results: Mean brake reaction time for the ankle fusion group (0.42+/-0.14 seconds) was significantly slower than for the control group (0.33+/-0.06 seconds) (p=0.03). The center of force was consistently isolated to the forefoot in the ankle fusion group compared to controls who distributed the center of force over both the forefoot and midfoot. There was no significant difference between the ankle fusion and control groups with respect to braking force, peak pressure, or contact area.
Conclusion: The mean brake reaction time following successful right ankle arthrodesis was significantly slower than that of normal controls. However, the fusion group time was still below the threshold for what is defined as a safe brake reaction time by the United States Federal Highway Administration.

Chemodynamic therapy (CDT) is an emerging antitumor strategy utilizing iron-initiated Fenton reaction to destroy tumor cells by converting endogenous HO into highly toxic hydroxyl radical (OH). However, the intratumoral overexpressed glutathione (GSH) and deficient acid greatly reduce CDT efficacy because of OH scavenging and decreased OH production efficiency. Even worse, the various physiological barriers, especially in glioma, further put the brakes on the targeted delivery of Fenton agents.

Purpose: Biodiesel is a non-toxic, renewable, and environmentally friendly fuel used in compression ignition engines. This work aimed to develop FeO/SiO as a cheap, magnetic, and easy separable catalyst for biodiesel production from waste oil by sono-catalytic transesterification.
Methods: Fe₃O₄-SiO₂ was prepared using a modified Stober method and used as a heterogeneous catalyst in an ultrasound-assisted transesterification reaction to produce biodiesel.

Flexible flatfoot is common among school-age children and significantly affects walking efficiency, balance stability, and joint-movement coordination in children. The demands on the skeletal structure and muscle function are increased during running; however, the impact of a flexible flatfoot on children's running capabilities is unclear. In this study, we aimed to investigate the effects of flexible flatfoot on the running function of school-age children.
