Chronic stress significantly affects neuron morphometry and function in the prefrontal cortex, a brain region controlling cognition and emotion. However, whether and how chronic stress regulates the maturation of NG2-expressing oligodendrocyte precursor cell (NG2(+) cell) and the importance of these changes remained unknown. Here, we report that exposing(More)
Glutathione peroxidase (GPX) is a crucial antioxidant selenocysteine (Sec) containing enzyme which plays a significant role in protecting cells against oxidative damage by catalyzing the reduction of hydroperoxides with glutathione (GSH). Several methods have been used to generate GPX mimics, however, only a few of these methods involved genetic engineering(More)
In this paper, we propose models to characterize diffusion dynamics in structured online social networks with push-based forwarding mechanism. We introduce the term user influence to characterize the average number of times that messages are browsed which is incurred by a given type user generating a message, and then propose a theoretical analysis approach(More)
In this paper, we propose models to characterize the process of opinion spreading in signed social networks under the impact of structure balance. We classify users into different types according to their positive link numbers, and define the term user influence to characterize the average number of times that users are influenced, which is incurred by a(More)
