Neuronal Mitochondrial Dysfunction Drives Astrocytic Mitochondrial Transfer after TBI: Reveals the Therapeutic Potential of astrocytic EV-Mito

在创伤性脑损伤后,神经元线粒体功能障碍会触发一种由星形胶质细胞介导的适应性反应,即通过细胞外囊泡转移线粒体以恢复胞体和神经突的生物能量学,尽管这种保护机制未能到达突触。

Root water-uptake depth and leaf trait adjustments along a water table gradient: trade-offs among trees and shrubs in a tropical coastal forest

这项研究表明,在热带海岸休息林(restinga forests)中,树木和灌木通过调整根系吸水深度以响应地下水位变化来维持水分状态,但这种地下投资产生了一种权衡,专门限制了树木的地上部分光合特征和绿度。

Sublethal Toxicity of Chlorpyrifos in the Freshwater Fish Puntius chola: Integrated Assessment of Behavioral Responses, Biochemical Alterations, and Histopathological Damage

本研究表明,亚致死剂量的有机磷杀虫剂毒死威(chlorpyrifos)暴露会导致淡水鱼类——乔氏鲃(*Puntius chola*)产生显著的代谢应激、碳水化合物与脂质谱的生化失衡以及严重的多种器官组织病理学损伤,凸显了其作为监测水生生态系统中农药污染的敏感生物标志物的潜力。

Streamline-Based Analysis: A novel framework for tractogram-driven streamline-wise statistical inference

本文引入了基于流线(Streamline-Based Analysis, SBA)的分析方法,这是一种新型非参数框架,它直接对单个纤维束追踪流线进行统计推断,以实现具有全脑白质高分辨率分析及族系误差控制的能力,从而弥合了体素级、纤维素级(fixel-)与纤维束级方法之间的鸿沟。
