EndoTac: An Endoscopic Camera‐Based Tactile Sensor with High Sensitivity for Minimally Invasive Surgery

open access: yesAdvanced Science, EarlyView.
EndoTac presents a trocar‐compatible endoscopic vision‐based tactile sensor that uses a convex mirror to enlarge side‐facing tactile coverage during minimally invasive vessel palpation. Distorted tactile images are unwarped and processed by a learning model to estimate vascular deformation, enabling sensitive, spatially distributed tactile perception ...

Stress Hyperglycemia Drives CD4+ T Cell PANoptosis and Postoperative Organ Injury via Monocyte‐Derived Succinate

open access: yesAdvanced Science, EarlyView.
High glucose is linked to reduced succinate dehydrogenase activity in CD14+ monocytes, accompanied by succinate accumulation and extracellular release. Extracellular succinate exacerbates mitochondrial ROS production and mtDNA release in CD4+ T cells. Cytosolic mtDNA then activates Z‐DNA binding protein 1 (ZBP1) and engages ZBP1‐associated inflammatory

Preoperative Pulmonary Care

open access: yesNihon Kikan Shokudoka Gakkai Kaiho, 2011
術前呼吸ケアの目的は全身状態の改善および術後の重篤な肺合併症を予防し早期離床を達成することである。このため術前評価と術後合併症を予測し,術式による呼吸機能障害の程度を把握する。喫煙者は非喫煙者と比較して有意に術後肺炎の発症が多いため少なくとも術前1カ月以上前に禁煙させることが推奨される。気道クリアランスについてのシステマチックレビューでは排痰法の有用性についての高いエビデンスは示されていない。このため個々の排痰法は患者の病態に合わせその利点,欠点を理解し施行することが重要である。またインセンティブスパイロメトリーは手術後に日常的に使用されているが,術後の有用性について高いエビデンスは示されていない。ところで肺癌,食道癌,頭頸部領域の癌は喫煙との関与が濃厚でありchronic obstructive ...

Alternating Shear Force of Respiration Regulates Cell Interactions of Fibroblasts and Macrophages to Promote Soft Tissue Integration of Chest Wall Polyetheretherketone Implants

open access: yesAdvanced Science, EarlyView.
Given that PEEK chest wall implants induce shear force at the soft tissue‐implant interface due to respiratory motion in the early in vivo post‐implantation stage. We confirmed that this mechanical stimulus triggers the PIEZO1/ITGB1/YAP1 signalling axis in L929 and the STAT6/p‐STAT6 pathway in RAW264.7, which in turn mediates adhesion and migration of ...

Application and Single‐Cell Regulation Mechanism of Engineered EVs Combined With 4D‐Printed Hydrogel for Infected Burn Repair

open access: yesAdvanced Science, EarlyView.
4D bioprinted hydrogel loaded with FGF2‐modified extracellular vesicles (4D@F‐EVs) targets dermal fibroblasts and elevates local wound FGF2 levels via sustained release of F‐EVs. It activates PI3K‐Akt signaling, restores critical KGF+ fibroblast–KGFR+ keratinocyte crosstalk, enhances robust angiogenesis and collagen deposition to efficiently repair ...
