Effects of warming and elevated O3 concentrations on N2O emission and soil nitrification and denitrification rates in a wheat-soybean rotation cropland

Verified

Yuanyuan Wang, Zhenghua Hu, Dongyao Shang, Ying Xue et al.

Journal: Environmental PollutionYear: 2019Citations: 32

The effects of warming and elevated ozone (O3) concentrations on nitrous oxide (N2O) emission from cropland has received increasing attention; however, the small number of studies on this topic impedes understanding. A field experiment was performed to explore the role of warming and elevated O3 con...

The prognostic value of admission lymphocyte-to-monocyte ratio in critically ill patients with acute myocardial infarction

Verified

Yuanyuan Zhao, Chunshu Hao, Xiangwei Bo, Zhengri Lu et al.

Journal: BMC Cardiovascular DisordersYear: 2022Citations: 17

BACKGROUND: Inflammation plays a critical role in acute myocardial infarction (AMI). Recent studies have shown the value of hematologic indicators in MI risk stratification and prognostic assessment. However, the association between lymphocyte-to-monocyte ratio (LMR) and the long-term mortality of c...

Characteristics of soil N2O emission and N2O-producing microbial communities in paddy fields under elevated CO2 concentrations

Verified

Zhurong Wu, Yuanyuan Wang, Chao Liu, Nan Yin et al.

Journal: Environmental PollutionYear: 2022Citations: 16

The effects of elevated carbon dioxide (CO2) concentration (e[CO2]) on nitrous oxide (N2O) emissions from paddy fields and the microbial processes involved in N2O emissions have recently received much attention. Ammonia-oxidizing microorganisms and denitrifying bacteria dominate the production of N2...

CIDEC silencing attenuates diabetic nephropathy via inhibiting apoptosis and promoting autophagy

Verified

Gaoshu Zheng, Yan‐min Tan, Yuanyuan Shang, Ya‐peng Liu et al.

Journal: Journal of Diabetes InvestigationYear: 2021Citations: 16

OBJECTIVE: The role of cell death-inducing DFF45-like effector C (CIDEC) in insulin resistance has been established, and it is considered to be an important trigger factor for the progression of diabetic nephropathy (DN). We intend to explore whether CIDEC plays an important role in the regulation o...
