Osteosarcoma is an aggressive form of bone cancer and affects the health in children and adolescents. Although conventional treatment improves the osteosarcoma survival, some patients have metastasis and drug resistance, leading to a worse prognosis. Therefore, it is necessary to explore the molecular mechanism of osteosarcoma occurrence and progression, which could discover the novel treatment for osteosarcoma.

More and more evidence shows that long non-coding RNA (lncRNA) plays an important role in the biological behavior of many kinds of malignant tumors, but the specific function of lncRNA Linc00657 in cervical cancer is still unknown. The purpose of this study is to explore the effect of Linc00657 on the malignant progression of cervical cancer and its potential mechanism. In two kinds of cervical cancer cell lines and normal cervical epithelial cells, qRT-PCR showed increased expression of Linc00657 in cervical cancer cells.

Coordinated and stable development of economy-energy-environment (3E) systems represents a long-term strategy for the sustainable development of humankind. Following the research idea of "indicator system construction-3E system evaluation-obstacles identification-optimization management," this article innovatively constructs a multiangle and comparable methodology system for evaluation and optimized management of the 3E system and considers the core cities of three economic circles in China as cases for empirical research. The results show that all the coordination degree levels were of good or high quality, which was at the highest level in the country.

Article Synopsis
  • The electrocatalytic water splitting method can be improved by using the oxidation of organic molecules instead of the traditional oxygen evolution reaction (OER).
  • The proposed reaction involves replacing OER with the oxidation of N-Boc-4-piperidine methanol (BPM), which successfully produces N-Boc-4-piperidine carboxaldehyde (BPC) in an environmentally friendly way.
  • Using amorphous NiFeO(OH) nanospheres as an anode catalyst resulted in nearly complete conversion of BPM to BPC within 15 hours and demonstrated almost 100% Faraday efficiency, indicating the process's effectiveness in green organic synthesis.

Wastewater treatment plants (WWTPs) are significant contributors to energy consumption and anthropogenic greenhouse gas (GHG) emissions. For achieving carbon reduction in the wastewater treatment industry, the direct and indirect GHG emissions generated by WWTPs need to be understood from a holistic perspective. This study estimated GHG emissions from WWTPs at the country scale by integrating process-based life cycle assessment and statistical data.

Based on data from 69 cities in the Yellow River Basin from 2006-2018, this paper examines the impact of environmental regulations on the integrated management of air pollution and CO emissions and its mechanism of action using a two-way stationary model. The results found that: (1) The impact of environmental regulations on air pollution and CO emissions in the Yellow River Basin has an inverted U-shaped trend, the intensity of regulation is still on the left side of the inverted U-shaped curve, and the inflection point has not yet appeared. (2) Environmental regulations suppressed air pollution and CO emissions by adjusting industrial structure, promoting technological innovation, and improving energy efficiency, but the current intensity of regulation is not sufficient to make the three paths fully effective.

To ensure food security, simultaneously achieving environmental protection and greenhouse gas (GHG) emission reduction has become a significant challenge in the sustainable development of China's chemical fertilizers (CFs) industry. Hence, this work attempt to construct a multi-objective optimization model (MOOM) based on crop yield, environment protection, and GHG emissions to adjust and optimize China's CFs structure (nitrogen, phosphate, potash, and compound fertilizers). The findings revealed that it's impossible to achieve the coordinated development of the three objectives only through the adjustment of CFs structure.

Osteosarcoma often occurs in children and adolescents and affects their health. The survival rate of osteosarcoma patients is unsatisfactory due to the lack of early detection and metastasis development and drug resistance. Hence, dissection of molecular insight into osteosarcoma initiation and progression is pivotal to provide the new therapeutic strategy.

The development of stable, low-cost, and highly efficient electrocatalysts for the N reduction reaction (NRR) process is challenging but crucial for ammonia production. Herein, we demonstrate the synthesis of pyrite nanoparticles wrapped by graphene oxide (FeS@GO) acting as a highly efficient NRR catalyst in a wide pH range. The FeS nanoparticles are uniformly dispersed across the GO nanosheet, thus leading to the fine exposure of active sites, the promotion of charge transfer, and the increment of a contact surface area, which are all beneficial for a desired catalyst.

Aquatic microorganisms in the sediment and water column are closely related; however, their distribution patterns between these two habitats still remain largely unknown. In this study, we compared sediment and water microeukaryotic and bacterial microorganisms in aquaculture ponds from different areas in China, and analyzed the influencing environmental factors as well as the inter-taxa relationships. We found that bacteria were significantly more abundant than fungi in both sediment and water, and the bacterial richness and diversity in sediment were higher than in water in all the sampling areas, but no significant differences were found between the two habitats for microeukaryotes.

Ammonia-oxidizing bacteria (AOB) and archaea (AOA) play important roles in nitrogen removal in aquaculture ponds, but their distribution and the environmental factors that drive their distribution are largely unknown. In this study, we collected surface sediment samples from ponds in three different areas in China that practice aquaculture. The community structure of AOB and AOA and physicochemical characteristics in the ponds were investigated.
