Programmable Pneumatic Actuator System for a Bioinspired Artificial Colon
Advanced Materials Technologies, EarlyView.A modular soft robotic colon simulator driven by programmable pneumatic actuation is developed to mimic physiological and pathological‐like motility patterns of the large intestine. Finite element–guided design and distributed control enable anatomically realistic deformation for peristalsis, segmentation, and mass movements, supporting capsule ...

Artificial intestinal valves in the surgery of the alimentary tract.
The Japanese Journal of Gastroenterological Surgery, 1984 telescoping anastomosisおよびnon-transected muscular valve形成法によって, 回盲弁に相当した機能をもった人工腸弁を作成した. この人工腸弁は一層の筋層, 特に内輪筋層の肥厚がその主体をなすもので, 順蠕動方向通過圧25cmH2O以下, 逆流圧40cmH2Oの弁機能を有する. かつ臨床例では形成後10年以上も初期機能を維持することが認められた. 臨床的に腸内容移送調節の目的で腸管広汎切除例7例に設置し, 6例に便性状, 便通の改善を認めた. 逆流防止機能を期待して設置した症例は胃全摘術5例, 胆道再建術10例, 先天性胆道閉鎖症22例, 空腸瘻, 結腸瘻各1例, Whipple手術, 膵嚢胞空腸吻合各2例, 合計43例で, いづれにも効果が認められた.

COLON ATRESIA IN COMBINATION WITH HIRSCHSPRUNG’S DISEASE: A RARE CLINICAL CASE
Учёные записки Санкт-Петербургского государственного медицинского университета им. Акад. И.П. Павлова, 2019 Introduction. Hirschsprung’s disease is a congenital anomaly characterized by the absence of ganglion cells in submucosal and intramuscular layers of intestinal wall that leads to the intestinal obstruction. 70–80 % of cases are isolated malformation but

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,

Advanced Science, EarlyView.A self‐assembled monolayer (≈0.9 nm) of an axially chiral binaphthol phosphoric acid derivative on a ferromagnetic Ni/NiOx substrate shows chiral‐induced spin selectivity (CISS) magnetoresistance of 50%–80%. This thermally and chemically robust functional stack shows the way towards practical spintronic devices based on the CISS effect.
