IL‐10 promotes malignant pleural effusion by regulating T_H1 response via an miR‐7116‐5p/GPR55/ERK pathway in mice

Kan Zhai, Xin‐Yu Shi, Feng‐Shuang Yi, Zhong‐Yin Huang, more

European Journal of Immunology > 50 > 11 > 1798 - 1809

IL‐10, produced by a wide variety of cells, is a highly pleiotropic cytokine that plays a critical role in the control of immune responses. However, its regulatory activity in tumor immunity remains poorly understood. In this study, we report that IL‐10 deficiency robustly suppressed the formation of malignant pleural effusion (MPE) and significantly enhanced miR‐7116‐5p expression in pleural CD4⁺...

Two‐stage randomized trial design for testing treatment, preference, and self‐selection effects for count outcomes

Yu Shi, Briana Cameron, Xian Gu, Michael Kane, more

Statistics in Medicine > 39 > 25 > 3653 - 3683

While the traditional clinical trial design lays emphasis on testing the treatment effect between randomly assigned groups, it ignores the role of patient preference for a particular treatment in the trial. Yet, for healthcare providers who seek to optimize the patient‐centered treatment strategy, the evaluation of a patient's psychology toward each treatment could be a key consideration. The two‐stage...

Hua‐Yu Shi, Zhongqiu Jia, Wanlong Wu, Xiang Zhang, more

Chemistry – A European Journal > 26 > 37 > 8190 - 8204

Various cathode materials have been proposed for high‐performance rechargeable batteries. Vanadyl phosphate is an important member of the polyanion cathode family. VOPO₄ has seven known crystal polymorphs with tunneled or layered frameworks, which allow facile cation (de)intercalations. Two‐electron transfer per formula unit can be realized by using V^V/V^IV and V^IV/V^III redox couples. The electrochemical...

Vertical Phase Separated Cesium Fluoride Doping Organic Electron Transport Layer: A Facile and Efficient “Bridge” Linked Heterojunction for Perovskite Solar Cells

Jianxing Xia, Junsheng Luo, Hua Yang, Fengjiao Zhao, more

Advanced Functional Materials > 30 > 27 > n/a - n/a

In perovskite solar cells (PSCs), the interfaces of the halide perovskite/electron transport layer (ETL) and ETL/metal oxide electrode (MOE) always attract and trap free carriers via the surface electrostatic force, altering quasi‐Fermi level (E_Fq) splitting of contact interfaces, and significantly limit the charge extraction efficiency and intrinsic stability of devices. Herein, a graded “bridge”...

Teng Yang, Leho Tedersoo, Xingwu Lin, Matthew C. Fitzpatrick, more

New Phytologist > 227 > 2 > 572 - 587

Soil fungi represent a major component of below‐ground biodiversity that determines the succession and recovery of forests after disturbance. However, their successional trajectories and driving mechanisms following wildfire remain unclear. We examined fungal biomass, richness, composition and enzymes across three soil horizons (Oe, A1 and A2) along a near‐complete fire chronosequence (1, 2, 8,...

An Ultrastrong and Highly Stretchable Polyurethane Elastomer Enabled by a Zipper‐Like Ring‐Sliding Effect

Chen‐Yu Shi, Qi Zhang, Cheng‐Yuan Yu, Si‐Jia Rao, more

Advanced Materials > 32 > 23 > n/a - n/a

Elastomers with excellent mechanical properties are in substantial demand for various applications, but there is always a tradeoff between their mechanical strength and stretchability. For example, partially replacing strong covalent crosslinking by weak sacrificial bonds can enhance the stretchability but also usually decreases the mechanical strength. To surmount this inherent tradeoff, a supramolecular...
