Effect of titanium dioxide nanoparticle (TiO₂‐NP) exposure in a novel Amur sturgeon Acipenser schrenckii hepatocyte cell line

Zhou Zhou, Ting Liu, Tianxun Luo, Zhenxing Zhao, more

Journal of Fish Biology > 105 > 3 > 894 - 906

In vitro cell culture is crucial for predicting the toxicity of titanium dioxide nanoparticle (TiO₂‐NP). However, assessing the toxicity of TiO₂‐NPs in sturgeon remains difficult given the lack of sufficient cell lines. We established and characterized the first hepatocyte cell line from Acipenser schrenckii liver tissue (ASL). This ASL cell line proliferated well in Dulbecco's modified Eagle's medium...

Almost strong equilibria for time‐inconsistent stopping problems under finite horizon in continuous time

Zhou Zhou

Mathematical Finance > 34 > 4 > 1089 - 1122

We consider time‐inconsistent stopping problems for a continuous‐time Markov chain under finite time horizon with non‐exponential discounting. We provide an example indicating that strong equilibria may not exist in general. As a result, we propose a notion of equilibrium called almost strong equilibrium (ASE), which is a weak equilibrium and satisfies the condition of strong equilibria except at...

A Less‐is‐More Strategy for Mitochondria‐Targeted Photodynamic Therapy of Rheumatoid Arthritis

Qingting Zuo, Jiayan Lyu, Xinran Shen, Fengju Wang, more

Small > 20 > 25 > n/a - n/a

Conventional photodynamic therapy (PDT) of rheumatoid arthritis (RA) faces a dilemma: low‐power is insufficient to kill pro‐inflammatory cells while high‐power exacerbates inflammation. Herein, mitochondrial targeting is introduced in PDT of RA to implement a “less‐is‐more” strategy, where higher apoptosis in pro‐inflammatory cells are achieved with lower laser power. In arthritic rats, chlorine 6‐loaded...

You Zhang, Wenzhong Ma, Jing Zhong, Ruiqiao Jiang, more

Journal of Applied Polymer Science > 141 > 15 > n/a - n/a

As an efficient method to realize photoinduced shape memory, photothermal filler has the characteristics of economy and convenience. However, the aggregation of the photothermal filler in the matrix material will reduce the material's shape memory and mechanical properties. In this work, the photothermal filler of reduced graphene oxide (rGO)‐titanium dioxide (TiO₂) was prepared by the solvothermal...
