Prognostic Impact of Bone Mineral Density Reduction During Neoadjuvant Chemotherapy (NAC) in Patients Undergoing NAC Followed by Esophagectomy for Esophageal Cancer

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
The association between BMD reduction during NAC and the worse prognosis remains unknown, although NAC followed by esophagectomy is a standard treatment for advanced ESCC. This study appeared that BMD massive reduction was an independent prognostic factor on OS (HR, 3.30; 95% confidence interval [CI], 1.69–6.55) and RFS (HR, 2.08; 95% CI, 1.19–3.63 ...

Real‐Time Force Monitoring of Electrically Stimulated 3D‐Bioengineered Muscle Bioactuators Using Organic Sensors with Tunable Sensitivity

open access: yesAdvanced Intelligent Systems, EarlyView.
The integration of sensing elements in bioengineered actuators is key to obtain real‐time information about their performance and further control/automation. By coupling flexible organic field‐effect transistor to a skeletal muscle actuator we demonstrate the feasibility to record in real‐time its contractile behavior when stimulated by electrical ...

Sensor‐Embedded Muscle for Closed‐Loop Controllable Actuation in Proprioceptive Biohybrid Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
Skeletal muscle tissue‐based bioactuators move in response to externally applied electrical stimuli in open‐loop control, which lacks knowledge of the actuator's state. Herein, a soft and fiber‐shaped piezoresistive mechanosensor that integrates with the soft tissue and operates in the cell culture environment is used to create the first proprioceptive

Spring and Power in Hovering Ornithopters

open access: yesAdvanced Intelligent Systems, EarlyView.
Only small ornithopters can hover, longest at the hummingbird size. This article reviews the drive and power of these hovering machines, focusing on elastic energy and thrust boosters. Unlike two‐winged designs, X‐winged and multiple‐V‐winged ornithopters benefit from lower disk loading and slower, smaller wingbeats, and the clap‐and‐fling effect ...
