Controlled Movement of Soft Actuators using Multi‐Responsive Microgel Arrays and Microcirculatory Systems

Advanced Functional Materials, EarlyView.
Microscale hydrogels (microgels) feature improved mass transport characteristics supportive of fast actuation and chemical tunability amenable to programmed stimuli response. A unique soft actuator architecture is realized by encapsulating microgels in soft microcirculatory systems which enable the convenient delivery of liquid stimuli for powering and

Cardiac Tamponade After Video-Assisted Thoracoscopy Surgical Diaphragmatic Plication

Annals of Thoracic Surgery Short Reports
Video-assisted thoracoscopy surgical diaphragmatic plication is the standard of care for diaphragmatic eventration. However, it is associated with complications like injuries to the bowel, liver, spleen, and lung parenchyma.

Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment

Advanced Functional Materials, EarlyView.
Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...

Using the Photostationary State of Arylazopyrazoles to Control Phase Transitions of Liquid Crystals

Advanced Functional Materials, EarlyView.
A series of new arylazopyrazole photoswitches is designed as dopants for liquid crystalline materials. Unprecedented, the distribution of photoisomers at the photostationary state upon irradiation with light of specific wavelengths (365, 460, 520 nm) is used to control the liquid crystalline phase transitions under isothermal conditions, including ...

Engineering Relative Spatial Structure of Dual Atomic Sites with Asymmetric Coordination for High‐Performance Hydrogen Evolution Activity

Advanced Functional Materials, EarlyView.
Dual‐atom catalysts featuring varying spatial configurations of metal sites (Pt1Fe1 DACs) are employed to systematically investigate the influence of spatial arrangements on the electronic structure and catalytic activity of active sites. Notably, the 3D asymmetric Pt1Fe1‐TAC dimer, featuring strong interatomic interactions, demonstrates superior ...

Robust Video List Decoding in Error-Prone Transmission Systems Using a Deep Learning Approach

IEEE Access
This paper introduces a novel deep-learning assisted video list decoding method for error-prone video transmission systems. Unlike traditional list decoding techniques, our proposed system uses a Transformer-based no-reference image quality assessment ...

Bio‐Orthogonally Crosslinked Supramolecular Polymer Bottlebrush Hydrogels for Long‐Term 3D Cell Culture

Advanced Functional Materials, EarlyView.
Fibrous benzenetrispeptide (BTP) hydrogels, fabricated via strain‐promoted azide‐alkyne cycloaddition (SPAAC) crosslinking, form robust, bioinert networks. These hydrogels can support 3D cell culture, where cell viability and colony growth depend on the fiber content.

VIDEO-ASSISTED THYROIDECTOMY

Japanese jornal of Head and Neck Cancer, 2003
当院は平成11年10月より内視鏡下甲状腺・副甲状腺切除を開始し, 現在まで副甲状腺腫3例 (1例は同時に甲状腺切除施行) と良性甲状腺腫71例を経験した。当初は前胸部あるいは腋窩からのアプローチ, あるいは片葉切除が必要な症例に対しては顎下部から行っていた。しかし, それらのアプローチでは広範囲の皮下剥離や長時間の手術に伴う侵襲性や器具にかかる費用など無視できない問題があった。平成12年9月より, 顎下部からの原法 (つりあげと小切開と2つのポートより施行) を改良し, 小切開創 (3cm) のみでの甲状腺片葉切除術を開始し, 53例を経験した。顎下部の創より上甲状腺動静脈を切断後, 内視鏡補助下で甲状腺峡部の切断および外側の剥離を行い, 甲状腺を創外に引き出し, 直視下に反回神経を確認 ...

Contact Lens with Moiré Patterns for High‐Precision Eye Tracking

Advanced Functional Materials, EarlyView.
This work presents a passive contact lens for high‐precision eye tracking, integrating a microscopic moiré grating label. The parallax‐induced shift of macroscopic moiré patterns enables angle measurement with 0.28° precision using a standard camera under ambient light.
