Highly Stable Photo‐Assisted Zinc‐Ion Batteries via Regulated Photo‐Induced Proton Transfer

Wenwen Zha, Qiushi Ruan, Long Ma, Meng Liu, more

Angewandte Chemie International Edition > 63 > 15 > n/a - n/a

Photo‐assisted ion batteries utilize light to boost capacity but face cycling instability due to complex charge/ion transfer under illumination. This study identified photo‐induced proton transfer (photo‐induced PT) as a significant process in photo‐(dis)charging of widely‐used V₂O₅‐based zinc‐ion batteries, contributing to enhanced capacity under illumination but jeopardizing photo‐stability. Photo‐induced...

The lipid droplet in cancer: From being a tumor‐supporting hallmark to clinical therapy

Yingfang Cui, Shuli Man, Jiejing Tao, Yu Liu, more

Acta Physiologica > 240 > 3 > n/a - n/a

Introduction Abnormal lipid metabolism, one of the hallmarks in cancer, has gradually emerged as a novel target for cancer treatment. As organelles that store and release excess lipids, lipid droplets (LDs) resemble “gears” and facilitate cancer development in the body. Aim This review discusses the life cycle of LDs, the relationship between abnormal LDs and cancer hallmarks, and the application...

A Double‐ligand Chelating Strategy to Iron Complex Anolytes with Ultrahigh Cyclability for Aqueous Iron Flow Batteries

Shaocong Wang, Long Ma, Shiyang Niu, Shibo Sun, more

Angewandte Chemie International Edition > 63 > 9 > n/a - n/a

Aqueous all‐iron flow batteries (AIFBs) are attractive for large‐scale and long‐term energy storage due to their extremely low cost and safety features. To accelerate commercial application, a long cyclable and reversible iron anolyte is expected to address the critical barriers, namely iron dendrite growth and hydrogen evolution reaction (HER). Herein, we report a robust iron complex with triethanolamine...

Orthopaedic Surgery > 16 > 1 > 207 - 215

Objective Intertrochanteric fracture is one type of hip fracture, which is the most serious consequence of osteoporosis. Along with the growing elderly population, intertrochanteric fracture is expected to rise increasingly. The aim of this study was to assess excess mortality after intertrochanteric fractures and to identify the predictors of long‐term mortality by therapy among patients aged 50...

Automatic Detection and Classification of Modic Changes in MRI Images Using Deep Learning: Intelligent Assisted Diagnosis System

Gang Liu, Lei Wang, Sheng‐nan You, Zhi Wang, more

Orthopaedic Surgery > 16 > 1 > 196 - 206

Objective Modic changes (MCs) are the most prevalent classification system for describing intravertebral MRI signal intensity changes. However, interpreting these intricate MRI images is a complex and time‐consuming process. This study investigates the performance of single shot multibox detector (SSD) and ResNet18 network‐based automatic detection and classification of MCs. Additionally, it compares...

Evolution of fluvial landscapes since the late Pleistocene at the Wangchenggang site of the Ying River Basin, Central China: Implications for the development and change of prehistoric settlements

Yinan Liao, Peng Lu, Duowen Mo, Ye Li, more

Geoarchaeology > 38 > 3 > 306 - 319

Reconstructing the evolution of fluvial landscapes is vital to our understanding of how and why early settlements used or abandoned locations in dynamic alluvial settings, especially places such as China's Central Plains where alluvial landforms have dominated since at least the late Pleistocene era. The Wangchenggang (WCG) site on the upper reaches of the Ying River is considered to be the legendary...

Sedimentary model of the Ediacaran Doushantuo cap carbonates from the southeastern margin of the Yangtze Block: Evidence from carbon and oxygen isotopes and elemental geochemistry

Guoming Dong, Guoqing Xiong, Yong Dan, Jun Dong, more

Geological Journal > 58 > 3 > 1012 - 1041

Cap carbonate of the early Ediacaran period represents an abrupt climate shift from severe Marinoan glaciation to a post‐glacial warm environment. Some consensuses on the distinctive negative excursion of δ¹³Ccarb and the origin of its unique sedimentary structures have been reached over the past decades, but certain aspects such as the distribution and redox conditions of cap carbonate still remain...

A natural halogenated fluoride adenosine analog 5′‐fluorodeoxy adenosine induced anticolon cancer activity in vivo and in vitro

Long Ma, Taohua Liu, Yingying Lu, Yanan Dong, more

Environmental Toxicology > 37 > 10 > 2493 - 2502

Adenosine (ADO) and its analogs have been introduced into the anticancer clinical trials, especial for the ADO derivatives with fluoride. The biosynthesis of fluorinase produces a fluorine‐containing ADO analog 5′‐fluorodeoxy adenosine (5′‐FDA). The toxicity and application of 5′‐FDA has not been evaluated, which limits the application of ADO analogs. In order to study its potential mechanism, we...
