845-猪模型全周层食管组织工程与功能整合研究
from 聊聊Sci
这篇研究报告了一种自体工程化食道的构建策略，旨在解决大段食道缺损修复中肌肉再生难和依赖支架的临床挑战。研究人员通过将自体生肌前体细胞与成纤维细胞微注射至去细胞化的猪食道支架中，并利用生物反应器预诱导促血管生成表型。通过对小型猪模型进行胸腔置换手术，实验证明该移植物在无免疫抑制的情况下实现了功能性整合。随后的多模态分析证实，移植物在六个月内逐渐恢复了原生组织结构，并展现出关键的神经肌肉再生与蠕动功能。这一创新方法为治疗包括先天性食道闭锁在内的严重食道病变提供了极具前景的临床转化方案。References: Durkin N, Hall G T, Lutman R, et al.

Deep Dream State
Neural Nets And Pretty Patterns
Deep Dream State is a full-cast dystopian sci-fi and desire horror audio drama by Neural Nets and Pretty Patterns. As the originating work of desire horror, it locates the uncanny inside wanting itself. While conventional horror positions you against a threat, desire horror implicates you in it. The horror emerges from recognition: the realization of why characters stay, and why surrender feels like relief. Since 2017, the show has used research in dream science, surveillance studies, behavioral economics, and advertising technology to examine systems of control through immersive sound design and full-cast performance.
