Proposed model of LL-37 induced mutagenesis.
, 2014 At sub-inhibitory concentrations, LL-37 can penetrate P. aeruginosa cells and enter the bacterial cytosol, where LL-37 dimers then bind to DNA. DNA binding by LL-37 then promotes DinB-dependent replication, which potentiates mutations in mucA leading to ...

Continuum Mechanics Modeling of Flexible Spring Joints in Surgical Robots
Advanced Robotics Research, EarlyView.A new mechanical model of a tendon‐actuated helical extension spring joint in surgical robots is built using Cosserat rod theory. The model can implicitly handle the unknown contacts between adjacent coils and numerically predict spring shapes from straight to significantly bent under actuation forces.

Roles and Mechanisms of Human Cathelicidin LL-37 in Cancer
, 2018 LL-37, the C-terminal peptide of human cathelicidin antimicrobial peptide (CAMP, hCAP18), reportedly increases resistance to microbial invasion and exerts important physiological functions in chemotaxis, promotion of wound closure, and angiogenesis ...

Advanced Robotics Research, EarlyView.Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...

LL-18 and FF-18 effectively inhibit EV71 infection.
(A-D) Cell viability of RD cells treated with the indicated amount of DL-37 (A), LL-37 (B), LL-18 (C), or FF-18 (D) was plotted against peptide concentration, and the cytotoxicity was determined.

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion
Advanced Robotics Research, EarlyView.A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

LL-37 promotes expression of IL-1β by human and murine myeloid cells in a P2X7R-independent manner.
, 2019 A and B) Primary human blood-derived monocytes were isolated, pretreated with 10 ng/ml E. coli 0111:B4 LPS for 3 hours, then exposed for 1 hour to 50 μg/ml LL-37, 5 mM ATP or untreated.

Hybrid Continuum Robot Designs and Architectures for Healthcare Applications
Advanced 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 ...

Consensus Formation and Change are Enhanced by Neutrality
Advanced Science, EarlyView.Neutral agents are shown to enhance both the formation and overturning of consensus in collective decision‐making. A general mathematical model and experiments with locusts and humans reveal that neutrality enables robust consensus via simple interactions and accelerates consensus change by reducing effective population size.
