Advanced Science, EarlyView.A snap‐top delivery nanosystem based on an azobenzene metal–organic framework achieves targeted release of 6‐mercaptopurine via acid‐stable frameworks and hypoxia/pH dual‐responsive β‐cyclodextrin gates. This multifunctional platform integrates three synergistic mechanisms: precision drug delivery to inflammatory sites, intrinsic antioxidant properties

Toxicology of the gastrointestinal tract
Folia Pharmacologica Japonica, 2008 消化管とは口腔から肛門までの管状の器官を指し，消化吸収に関連する舌，各種の唾液腺，膵臓，肝臓，胆嚢を含めて消化器と称する．消化管の基本構造は，粘膜，筋層，漿膜の3層より成り，筋層内には脊髄に匹敵するほどのニューロンを有する腸管神経系を持ち交感・副交感神経を介して中枢神経と連携するとともに，粘膜に存在する多種類の神経内分泌細胞とその消化管ホルモンにより，微妙な制御がなされている．医薬品開発上の安全性試験で遭遇する消化管毒性の主な症状所見として悪心・嘔吐，排便異常，便の性状異常，鼓腸などがあり，何れも注意深い動物の観察が重要である．消化管毒性の組織変化としては，粘膜の出血，粘膜の損傷・再生，粘膜の欠損すなわちびらん・潰瘍，炎症，粘膜の萎縮，消化管の癒着，リン脂質 ...

Advanced Science, EarlyView.This study presents an anatomical landmark‐guided DRL framework for autonomous wireless capsule endoscopy navigation. Using a lightweight edge‐contour‐depth fusion module, it achieves over 97% coverage across diverse gastric anatomies. To ensure reliability, a two‐stage sim‐to‐real pipeline with an adaptive dynamic programming controller mitigates ...

Advanced Science, EarlyView.Inspired by natural amino acid polymer‐melanin systems, this study strategically incorporated tellurocysteine to develop advanced radiation‐shielding materials. This approach transformed the primary interaction mechanism between melanin‐based materials and incident photons from Compton scattering to the photoelectric effect. Tellurocysteine‐polymerized
