Toxicology of the respiratory system

Folia Pharmacologica Japonica, 2009
呼吸器は，空気から酸素を取り入れ血液から二酸化炭素を放出するガス交換を行うための器官である．空気中に存在す化学物質は呼吸を通して体内に入るため，呼吸器はこれらの化学物質に最初に接触しその影響を最も受けやすい器官である．このため，大気汚染物質による健康障害では呼吸器が標的器官となることが多い．医薬品の分野では，吸入以外の経路でも抗癌剤等による薬剤性肺障害の報告があり，本誌でも詳しい総説がある（1）．また，近年は経鼻投与など経気道的に投与する薬剤の実用化が進んでおり，医薬品の開発に際して鼻腔などの気道を含む呼吸器への直接的な接触による副作用が課題になってきている．本稿では，鼻腔等の気道を中心として，呼吸器の構造と機能，呼吸器毒性の検査法，薬剤等による呼吸器毒性について概説する．

A Sacrificial 3D Printed Vessel‐on‐Chip Demonstrates a Versatile Approach to Model Granulation Tissue

Advanced Healthcare Materials, EarlyView.
A novel method that combines 3D printing and organ‐on‐chip technology enables the creation of hollow channels lined with endothelial cells through a fibroblast‐populated connective tissue matrix. The model supports stable metabolic culture conditions, angiogenic sprouting, and immune cell migration, thereby demonstrating an easy and versatile method to

Molecular biomarkers and toxic consequences of impact by organic pollution in aquatic organisms [PDF]

, 1994
Organic contaminants are readily bioaccumulated by aquatic organisms. Exposure to and toxic effects of contaminants can be measured in terms of the biochemical responses of the organisms (i.e. molecular biomarkers).

Exploring the potential anti-senescence effects of soybean-derived peptide Soymetide in mice hippocampal neurons via the Wnt/β-catenin pathway

Frontiers in Pharmacology
Soybean-based foods enhance cognitive functions by influencing hippocampal mechanisms. These salutary effects have so far been attributed to isoflavones present in soybeans.

Platelet Lysate–Enriched Human Induced Pluripotent Stem Cell–Derived Chondrocyte Sheets for Bone Defect Repair via Endochondral Ossification

Advanced Healthcare Materials, EarlyView.
Human iPSC‐derived hypertrophic chondrocyte sheet promotes bone regeneration. Abstract Bone defects are a major clinical challenge, primarily owing to the limited self‐healing capacity of bones and the high risk of complications associated with conventional treatment strategies.

Lipidome atlas of p53 mutant variants in pancreatic cancer

Biology Direct
Mutations in the tumour suppressor protein p53 are present in 70% of human pancreatic ductal adenocarcinomas (PDAC), subsequently to highly common activation mutation of the oncogene KRAS. These p53 mutations generate stable expression of mutant proteins,
