Unraveling El Niño's impact on the East Asian Monsoon and Yangtze River summer flooding

Verified

Wenjun Zhang, Fei‐Fei Jin, Malte F. Stuecker, Andrew T. Wittenberg et al.

Journal: Geophysical Research LettersYear: 2016Citations: 173

Abstract Strong El Niño events are followed by massive summer monsoon flooding over the Yangtze River basin (YRB), home to about a third of the population in China. Although the El Niño–Southern Oscillation (ENSO) provides the main source of seasonal climate predictability for many parts of the Eart...

Strong sub-seasonal wintertime cooling over East Asia and Northern Europe associated with super El Niño events

Verified

Xin Geng, Wenjun Zhang, Malte F. Stuecker, Fei‐Fei Jin

Journal: Scientific ReportsYear: 2017Citations: 82

East Asia experienced a record-breaking cold event during the 2015/16 boreal winter, with pronounced impacts on livelihood in the region. We find that this large-scale cold spell can be attributed to the concurrent super El Niño event in the tropical Pacific. Our analysis reveals that all super El N...

Tandem Guest‐Host‐Receptor Recognitions Precisely Guide Ciprofloxacin to Eliminate Intracellular <i>Staphylococcus aureus</i>

Verified

Wenjun Zhan, Lingling Xu, Zhiyu Liu, Xiaoyang Liu et al.

Journal: Angewandte Chemie International EditionYear: 2023Citations: 51

Staphylococcus aureus (S. aureus) is able to hide within host cells to escape immune clearance and antibiotic action, causing life-threatening infections. To boost the therapeutic efficacy of antibiotics, new intracellular delivery approaches are urgently needed. Herein, by rational design of an ada...

Sustained Release of Neuroprotective Drugs Curcumin and Edaravone from Supramolecular Hydrogel for Ischemic Stroke Treatment

Verified

Yanpeng Jia, Yi Zhang, Wenjun Zhan, Yu Wang et al.

Journal: Advanced Functional MaterialsYear: 2023Citations: 49

Abstract Ischemic stroke is a major cause of death and disability worldwide. The poor drug delivery to cerebral ischemic regions remains a challenging issue for ischemic stroke treatment. Curcumin (Cur) and edaravone (EDV) show remarkable therapeutic effects on ischemic stroke. However, the short ha...

Urinary exosomes derived circRNAs as biomarkers for chronic renal fibrosis

Verified

Yuhan Cao, Yuanhui Shi, Yanlang Yang, Zhangli Wu et al.

Journal: Annals of MedicineYear: 2022Citations: 35

BACKGROUND: Chronic renal disease (CKD) is a common and irreversible loss of renal function. Renal fibrosis reflected the degree of renal dysfunction. However, the current biomarkers only characterize the renal function instead of indicating the fibrosis degree. The potential diagnostic value of uri...

Modulation of the ENSO on Winter Aerosol Pollution in the Eastern Region of China

Verified

Jiaren Sun, Haiyan Li, Wenjun Zhang, Tairu Li et al.

Journal: Journal of Geophysical Research AtmospheresYear: 2018Citations: 35

Abstract The modulation of the El Niño/Southern Oscillation (ENSO) on winter aerosol pollution (WAP) in the eastern region of China (ERC) was investigated from a climatological perspective. The results show that the weakened East Asian winter monsoon during El Niño events has an important influence ...

Exhaled breath diagnostics of lung and gastric cancers in China using nanosensors

Verified

Alaa Gharra, Yoav Y. Broza, Guiping Yu, Weidong Mao et al.

Journal: Cancer CommunicationsYear: 2020Citations: 33

Dear Editor, Breath analysis is a promising diagnostic approach for various conditions [1, 2]. It is based on the identification of volatile organic compounds (VOCs) emitted in the breath, which creates a unique volatolomic signature [3]. Owing to their characteristics, VOCs can be measured non-intr...
