823-氢气辅助软骨细胞移植治疗骨关节炎
from 聊聊Sci
这项研究通过局部持续氢气供应，成功解决了骨关节炎（OA）环境下移植细胞存活率低和表型丢失的医学难题。研究团队开发了一种基于二硅化钛（TiSi2）纳米片的新型水凝胶，该材料能在生理环境下稳定释放氢气超过两个月，从而有效对抗氧化应激与炎症。实验证明，氢气能显著维持干细胞衍生软骨球的活性及其透明软骨特征，避免其发生纤维化或肥大。在大型动物羊的临床模型中，这种氢辅助移植策略实现了受损软骨的高效修复，并在六个月内逆转了骨关节炎的病理进程。该成果为治疗具有挑战性的退行性关节疾病提供了极具临床转化潜力的细胞治疗方案。References: Chen S, Luo M, Chen S, 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.
