Heliyon

November 2024

School of Environmental and Municipal Engineering, Lanzhou Jiao Tong University, Lanzhou, 730070, China.

To improve the oxidation pretreatment efficiency of wastewater from organic peroxides, a catalyst (CeO-C catalyst) was developed using the calcination method with ceramic particles as the support. The crystalline structure and elemental composition of the CeO-C catalyst were characterized by Scanning Electron Microscope (SEM), Energy Dispersive Spectrometer (EDS), and X-ray diffraction (XRD). This study explored the effects of CeO mass ratio, calcination temperature, and calcination time on the performance of the catalyst.

Wetland ecosystems store large amounts of carbon, and CO and CH fluxes from this ecosystem receive the double impact of climate change and human activities. Nonetheless, research on how multi-gradient warming and nitrogen and phosphorus additions affect these wetland greenhouse gas emissions is still limited, particularly in alpine wetland ecosystems. Therefore, we conducted a field experiment on the Tibetan Plateau wetlands, investigating the effects of warming and nitrogen and phosphorus additions on the CO and CH fluxes in alpine wetlands.

School of Environmental Science & Engineering, Shanghai Jiao Tong University, 800 Dongchuan Road, Shanghai 200240, China; Campus for Research Excellence and Technological Enterprise (CREATE), National University of Singapore, 1 CREATE Way, 138602, Singapore; China-UK Low Carbon College, Shanghai Jiao Tong University, 800 Dongchuan Road, Shanghai 200240, China. Electronic address:

Constructed wetland (CW) is considered a promising technology for the removal of emerging contaminants. However, its removal performance for antibiotic resistance genes (ARGs) is not efficient and influence of virulence factor genes (VFGs) have not been elucidated. Here, removal of intracellular and extracellular ARGs as well as VFGs by electricity-intensified CWs was comprehensively evaluated.

School of Environmental Science and Engineering, Shanghai Jiao Tong University, 800 Dongchuan Road, Shanghai, 200240, China; China-UK Low Carbon College, Shanghai Jiao Tong University, 800 Dongchuan Road, Shanghai, 200240, China.

Article Synopsis
  • Fluoroquinolone antibiotics and antibiotic resistance genes (ARGs) are not effectively removed by conventional wastewater treatment plants (WWTPs), highlighting the need for better methods.
  • Denitrification co-metabolism was studied to see if it could improve the efficiency of antibiotic removal, with varying results depending on the carbon source used for different denitrifying communities.
  • The findings indicate that the choice of carbon source significantly affects both the removal of antibiotics and the spread of ARGs, suggesting a strategic approach to enhance wastewater treatment processes.

Clarifying the responses of human activities and climate change to the water cycle under variable environments is crucial for accurately assessing regional water balance. An analysis of the changes in actual evapotranspiration and its driving factors was conducted in the global high-elevation mountains during the period from 2001 to 2022. Utilizing 18 formulas for calculating evapotranspiration, which are based on comprehensive, temperature, radiation, and mass transfer, and then simulated the variations in reference evapotranspiration.

Root rot is a very destructive soil-borne disease, which severely affects the quality and yield of in major planting areas of Gansu Province, China. Twelve strains were identified from root rot tissue and infected soil in the field by comparing each isolate strain internal transcribed spacer, translation elongation factor 1-α sequence and RNA polymerase second largest subunit gene with the sequences of known fungal species in the NCBI database. Of these isolates, four were , followed by three , two , and one each of , , and .

Here, an enzyme-free lateral flow aptasensor was designed by target-induced strand-displacement effect and followed by the activation of multi-component nucleic acid enzyme (MNAzyme)-mediated cleavage to enable rapid and portable ochratoxin A (OTA) detection. The substrate was prepared as an oligonucleotide strand modified with magnetic beads (MB) and human chorionic gonadotropin (hCG). The interaction of OTA with the aptamer induces the release of blocking DNA, which hybridized with three separated subunits of DNA, forming a sequence-specific MNAzyme catalytic core.

Research on polyurethane-modified asphalt has become very popular. To this end, researchers have explored different ways, such as the use of polyurethane, to improve the road performance of asphalt. However, according to existing experimental research findings, it seems that the use of polyurethane alone cannot completely improve the road performance of asphalt.

Article Synopsis
  • Cervical cancer is highly prevalent in women, and this study explored how Schisandrin B (Sch B), a compound from a Chinese herb, enhances the effects of docetaxel (DTX) in targeting cervical cancer growth and invasion.
  • The research involved treating Caski cells with Sch B and DTX, using various methods to assess cell viability, apoptosis, and invasion, followed by assessments in animal models to confirm the findings over a month-long treatment period.
  • Results showed that Sch B, when combined with DTX, significantly improved anti-tumor outcomes by reducing cell viability, inhibiting colony formation, increasing apoptosis, and downregulating proteins associated with tumor progression, suggesting a promising combined therapy for cervical cancer

Serious concerns have been raised regarding antibiotic resistance genes (ARGs) with respect to their potential threat to human health. Wastewater treatment plants (WWTPs) have been considered to be hotspots for ARGs. In this study, high-throughput quantitative polymerase chain reaction (HT-qPCR) was used to profile size-dependent ARGs and mobile genetic elements (MGEs) divided by particle-associated (PA) assemblages (>3.

Safety Assessment of Electromagnetic Exposure in High-Speed Train Carriage with Full Passengers.

Ann Work Expo Health

October 2020

Key Laboratory of Opto-Technology and Intelligent Control Ministry of Education, Lanzhou Jiao Tong University, No. 88 Anning West Road, Anning District, Lanzhou, China.

The objective of this work is to evaluate the safety of the electromagnetic environment in the carriage of high-speed trains exposed to power cables when the train is full of passengers. The electromagnetic model of a real carriage, two sets of power cables and the 84 passengers were set up by using COMSOL Multiphysics software based on CRH5. The distributions of induced electric and magnetic fields in the carriage, inside and on the surface of passengers were investigated.

Gene therapy is a promising therapeutic approach for chemoresistant cervical cancers. Therapeutic interventions targeting the key factors contributing to the initiation and progression of cervical cancer may be a more effective treatment strategy. In the present study, we firstly determined the expression of protein tyrosine phosphatase receptor J (PTPRJ) in 8-paired human cervical tumor and non-tumor tissues.

[Relationships between river water quality and land use type at watershed scale].

Ying Yong Sheng Tai Xue Bao

July 2013

School of Environmental and Municipal Engineering, Lanzhou Jiao-tong University, Lanzhou 730070, China.

Based on the remote sensing images of 54 water quality monitoring stations within the Suzi River watershed, the riparian buffer zones at 6 scales were constructed by ArcGIS, and the 8 landscape indices at landscape and class levels were calculated with FRAGSTATS software. A correlation analysis on the landscape indices and river water quality was made from the viewpoints of landscape space pattern and composition. In the watershed, the landscape pattern in different riparian buffer zones had different effects on the river water quality.
