Delving into the unknown: Obscure etiologies of gastrointestinal bleeding

International Journal of Gastrointestinal Intervention
Gastrointestinal (GI) bleeding is a medical emergency with diverse etiologies. It ranges from most common conditions like peptic ulcers to rare presentations with diagnostic challenges. While most cases arise from familiar sources, clinicians must remain

A Microgel Platform Enables Site‐Specific Intestinal Delivery of Lactoferrin, Improving its Bioavailability for Targeted Alleviating Liver Injury and Colitis

Advanced Science, EarlyView.
This work first time reports an eco‐friendly desert plant food‐based polysaccharide ASKP microgels which have intestinal site‐specific release properties which can achieve small‐intestine or colon targeting capability via different cross‐linking chemistry.

A Multimodal Magnetically Driven Soft Robot With Integrated Actuation‐Sensing Based on Photothermal Reprogramming Technology

Advanced Science, EarlyView.
This work reports a thermally safe, photothermally reprogrammable magnetic soft robot with its reprogramming temperature tuned to ∼39.5°C for biocompatibility. It achieves multimodal locomotion (max speed of 1.8 BL/s) and integrates liquid‐metal capacitive sensing to monitor self‐motion and detect environmental changes in simulated gastric environments,

SuFEx‐Enabled Reprogramming of Flavonoids for Selective α‐Glucosidase Covalent Inhibition

Advanced Science, EarlyView.
Selective inhibition of intestinal α‐glucosidase remains limited by poor enzyme specificity and off‐target metabolic effects. Here, SuFEx click chemistry is used to reprogram natural flavonoids into covalent inhibitors with enhanced α‐glucosidase selectivity and controlled reactivity. This strategy enables effective regulation of carbohydrate digestion

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 ...

An Edible Biohybrid Platform Accomplishes In Situ Fenton‐Mediated Enteral Nanoplastics Aging and Excretion

Advanced Science, EarlyView.
An edible biohybrid platform triggers nanoplastics (NPs) aging and agglomeration by in situ generating hydroxyl radicals within the intestine. The enlarged NPs are unable to penetrate the intestine and are subsequently excreted. Simultaneously, probiotic biofilms reinforce the intestinal barrier.

In‐Process Magnetization for 3D Printing of Magnetorheological Elastomer with Heterogeneous Magnetic Profile for Anisotropic Actuation

Advanced Science, EarlyView.
Fully programmable, in‐process 3D magnetization integrated with multi‐material printing enables soft magnetic systems with precise actuation and sensing. Discrete and continuous magnetization profiles drive bending, morphing, and locomotion, demonstrated through strain‐sensing elements, dragonfly‐inspired wings, octopus‐like tentacles, and a serpentine

Microplastics‐Induced Gut Microbiota Dysbiosis Accelerates Alzheimer's‐Like Pathology and Cognitive Decline via the Gut–Brain Axis

Advanced Science, EarlyView.
Microplastics (MPs) breach the gut‐brain axis by triggering taurine‐depleting microbiota dysbiosis that accelerates Alzheimer‐like pathology in 5XFAD mice. Taurine supplementation normalizes autophagy, microglial quiescence, and cognition, and plasma taurine inversely tracks cognitive decline in ADNI participants, revealing a readily translatable ...

A Modular PLUG‐IN Photosynthetic Chassis With Tunable Thermal Control for Mammalian Systems

Advanced Science, EarlyView.
This work establishes a “plug‐in” chassis compatible with mammalian systems that synchronizes growth, production, and cell‐wall re‐configuration, providing a versatile platform for photosynthetic bioproduction and microalgal synthetic biology. ABSTRACT Microalgae are promising photosynthetic platforms for high‐value compounds, yet their industrial use ...
