Interactions of Fe, Mn, Zn, and Cd in Soil-Rice Systems: Implications for Reducing Cd Accumulation in Rice.

Cadmium (Cd) contamination in rice ( L.) poses serious health risks for human, necessitating effective mitigation strategies. This study investigated the effects of Cd stress on iron (Fe), manganese (Mn), zinc (Zn), and Cd accumulation and translocation in rice varieties with high (MY46) or low (ZS97B) Cd accumulation capacities grown in acidic and alkaline soils.

Association between neutrophil percentage-to-albumin ratio and mortality in Hemodialysis patients: insights from a prospective cohort study.

Background: The neutrophil percentage-to-albumin ratio (NPAR) emerges as a novel inflammation marker, demonstrating prognostic ability in a variety of cardiovascular diseases. However, its impact on mortality among patients undergoing maintenance hemodialysis (MHD) remains uncertain. Our research aims to determine whether NPAR is a reliable predictor of mortality in MHD patients.

Asymmetric environmental responses on evapotranspiration in Tibetan Plateau grassland.

Evapotranspiration (ET) from the Tibetan Plateau (TP) grasslands plays a critical role in regulating water storage in the Asian Water Tower. However, the patterns, drivers, and responses of ET to climate change remain largely understudied due to limited observational data. This study integrated eddy covariance and long-term remote sensing data to examine the spatial patterns of ET and its drivers across the TP, comparing these patterns with those in other grassland ecosystems of the Northern Hemisphere.

Research Progress on the Effects of Support and Support Modification on the FTO Reaction Performance of Fe-Based Catalysts.

In recent years, the non-petroleum production of light olefins has been the research focus of Fischer-Tropsch olefin synthesis (FTO). Iron-based catalysts have attracted much attention because of their low price, high catalytic activity, and wide temperature range. In this paper, traditional modification, hydrophobic modification, and amphiphobic modification of the catalyst are summarized and analyzed.

Investigation on maintenance hemodialysis patients with mineral and bone disorder in Anhui province, China.

Background: Chronic kidney disease-mineral bone disorder (CKD-MBD) is a common comorbidity in patients with CKD. The study aims to describe the control rates of serum-corrected calcium (Ca), phosphate (P) and intact parathyroid hormone (iPTH) and its risk factors among maintenance hemodialysis (MHD) patients in Anhui Province of China.

Methods: The study was conducted in 27 hemodialysis centers of Anhui Province between January 1st 2020 and December 31th 2020.

Identifying the dominant impact factors and their contributions to heatwave events over mainland China.

The heatwave frequency and intensity have significantly changed as the climate warms and human activities increase, which poses a potential risk to human society. However, the impact factors that determine the change of heatwave events remain unclear. Here, we estimated the heatwave events based on data from 2474 in-suit gauges during 1960-2018 at daily scale in China.

Varying response of vegetation to sea ice dynamics over the Arctic.

Recent reduction of sea ice may have contributed to vegetation growth over the Arctic through albedo feedback effects to atmospheric warming. Understanding the varying response of vegetation to sea ice dynamics is critical for predicting future climate change over the Arctic and middle-high latitudes. Instead of looking at the direct response characteristics, we perform a systematic analysis of the time-lag and time-cumulation responses of vegetation to sea ice dynamics, using a long-term Arctic Normalized Difference Vegetation Index (NDVI) dataset and three sea ice indices (sea ice concentration (SIC), sea ice area (SIA) and sea ice extent (SIE)) from 1982 to 2015.
