The role of the msaABCR operon in implant-associated chronic osteomyelitis in Staphylococcus aureus USA300 LAC

open access: yesBMC Microbiology, 2020
Background The msaABCR operon regulates several staphylococcal phenotypes such as biofilm formation, capsule production, protease production, pigmentation, antibiotic resistance, and persister cells formation.

Investigation of factors affecting loosening of ilizarov ring‐wire external fixator systems at the bone‐wire interface [PDF]

open access: yesJournal of Orthopaedic Research, 2011
AbstractThe potential for peri‐implant bone yielding and subsequent loosening of Ilizarov ring‐wire external fixation systems was investigated using non‐linear finite element (FE) analyses. A strain‐based plasticity model was employed to simulate bone yielding.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

open access: yesAdvanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Gait Analysis of Pak Biawak: A Necrobot Lizard Built using the Skeleton of an Asian Water Monitor (Varanus Salvator)

open access: yesAdvanced Robotics Research, EarlyView.
Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

Predeformation loading capacity of various stopper types of Kirschner wires

open access: yesActa Orthopaedica et Traumatologica Turcica, 2021
The predeformation loading capacity of five different stopper configurations of Kirschner wires are evaluated quantitatively on an experimental model by using the Instron device. Traction forces were applied to Kirschner wires with normal beaded stoppers

Muscle Control of an Extra Robotic Digit

open access: yesAdvanced Robotics Research, EarlyView.
This study compares muscle‐ and movement‐based control for operating a supernumerary robotic thumb. While movement control performs better in the proposed tasks, muscle‐based (EMG) control promotes broader motor learning. The results highlight the promise and challenges of using biosignals for human augmentation, offering new insights into intuitive ...

Hybrid Continuum Robot Designs and Architectures for Healthcare Applications

open access: yesAdvanced Robotics Research, EarlyView.
Hybrid continuum robots represent an emerging class of flexible manipulators that blend materials, structures, and actuation concepts from the established fields of soft and continuum robotics. This review introduces an accessible framework to distinguish key hybridization approaches, surveys current designs aimed at complex clinical applications, and ...

The Development of a Novel Bone Filler, Titanium Wire Ball.

open access: yesActa medica Okayama, 2017
In designing bone fillers, hardness has heretofore not been a major concern. Fillers are typically very hard and thus often accelerate the collapse of the adjacent bones. We developed a novel, relatively soft bone filler, whose hardness is similar to the human cancellous bone.

Bioinspired Soft‐Skeleton Robotics With Cooperative Shape Transformation and Stiffness Adaptation

open access: yesAdvanced Robotics Research, EarlyView.
A bioinspired soft‐skeleton robot that integrates variable‐stiffness chain skeletons into a soft textile skin is developed. The chain skeletons are highly flexible initially but can stiffen upon pneumatic actuation, enabling large deformation and enhanced load‐bearing capacity.
