717-西地那非对莱氏综合征的治疗潜力研究
from 聊聊Sci
这项发表在《Cell》上的研究通过诱导多能干细胞 (iPSC) 技术，为患有莱氏综合征 (Leigh Syndrome) 这一严重线粒体疾病的患者寻找治疗方案。科研人员利用患者细胞构建了模型，并从五千多种现有药物中筛选出西地那非 (Sildenafil) 作为潜在的转基因治疗候选药。实验证明，这种药物能够有效修复线粒体功能，改善神经发育缺陷，并显著延长患病动物模型的寿命。临床上，六名接受该药物治疗的患者在运动能力和代谢稳定性方面均表现出明显好转。该研究不仅揭示了西地那非调节神经通路的作用机制，还证明了老药新用在治疗罕见遗传病方面的巨大潜力。References: Zink A, Dai D F, Wittich A, 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.
