Have Agricultural Land-Use Carbon Emissions in China Peaked? An Analysis Based on Decoupling Theory and Spatial EKC Model

28 Apr 2024  |  MDPI
China's agricultural land-use carbon emissions (ALUCEs) peaked at 396.9 Mt C-eq in 2015 and have since plateaued, with emissions from agricultural materials and soil management declining, while those from rice cultivation and livestock breeding remain stable or rising. The study uses decoupling theory and the Environmental Kuznets Curve (EKC) model to confirm the robustness of the peaking process, revealing an N-shaped relationship between ALUCEs and agricultural GDP. The findings suggest that while emissions have plateaued, continued efforts are needed to ensure a transition to a declining phase, with significant regional variations in emission trends and decoupling states.

Correlation analysis of serum TLR4 protein levels and TLR4 gene polymorphisms in gouty arthritis patients

23 Apr 2024  |  journals.plos.org
The study investigates the correlation between TLR4 gene polymorphisms and protein expression in gouty arthritis patients. It finds that the AG genotype of the TLR4 gene rs2737191 polymorphism is associated with an increased risk of gouty arthritis, with higher TLR4 protein levels observed in patients compared to healthy controls. The research highlights the role of genetic factors and inflammatory pathways in the pathogenesis of gout, suggesting that targeting the TLR4-NF-κB signaling pathway could be a potential therapeutic approach. The study emphasizes the importance of genetic screening and lifestyle modifications in managing gout risk.

Recent Advances and Challenges in Anion Exchange Membranes Development/Application for Water Electrolysis: A Review

It discusses the challenges of hydrogen production efficiency, long-term stability, and cost-effectiveness. The review also explores future research directions for the commercialization of AEMs, emphasizing the need for improved ion conductivity and alkaline stability. The study is supported by the National Natural Science Foundation of China and the State Key Laboratory of Organic-Inorganic Composites.

To provide reliable water in a warming world, cities are testing small-scale treatment systems and wastewater recycling

04 Apr 2024  |  techxplore.com
The article discusses the challenges faced by large urban water systems, such as malfunctions, leaks, and water shortages exacerbated by climate change. It highlights the growing trend of cities experimenting with small-scale, decentralized water treatment and recycling systems to improve water security and reduce reliance on centralized infrastructure. The author, who studies water systems, explains how these distributed systems work and their benefits, including cost-effectiveness, ease of maintenance, and environmental advantages. Examples from cities like El Paso, Austin, San Francisco, and Windhoek in Namibia are provided to illustrate the practical application of these systems. The article also touches on technological advancements that make water treatment more efficient and the potential for hybrid systems that combine centralized and decentralized approaches. Despite the benefits, the article notes that public perception and the need for robust business models and governance structures are challenges to the widespread adoption of decentralized water systems.

How to provide reliable water in a warming world – these cities are testing small-scale treatment systems and wastewater recycling

04 Apr 2024  |  businessdailymedia.com
The article discusses the challenges faced by large urban water systems, such as malfunctions, leaks, and water scarcity exacerbated by climate change. It highlights the growing trend of cities experimenting with small-scale, decentralized water treatment systems as an alternative to traditional centralized systems. These systems, which include wastewater recycling and localized treatment, can be more cost-effective, easier to maintain, and enhance water security. The author, who studies water systems, explains how natural processes of water purification can be mimicked by modern technology. Examples from cities like El Paso, Austin, and Windhoek are provided to illustrate the implementation of decentralized systems. The article also explores the potential of hybrid systems, combining centralized and decentralized sources, to improve water supply resilience, as demonstrated by a model of Houston. Advanced technologies like membrane-based processes and microbial fuel cells are mentioned as promising methods for water reclamation.

How to provide reliable water in a warming world – these cities are testing small-scale treatment systems and wastewater recycling

04 Apr 2024  |  metropolitandigital.com
The article discusses the challenges faced by large urban water systems, such as malfunctions and leaks, and the growing problem of water shortages exacerbated by climate change. It highlights the shift some cities are making towards small-scale, decentralized water treatment and recycling systems. These systems, which can be standalone or hybrid models integrated with centralized systems, are designed to treat and reuse water locally. The author, who studies water systems, explains that decentralized systems can be more cost-effective, easier to maintain, and environmentally beneficial. The article also explores how technology is advancing to make water more reusable, with examples of membrane-based and electrochemical processes, microbial fuel cells, and energy recovery from biogas. A case study of Houston is presented to show how hybrid systems can improve water supply and pressure, and limit contamination risks. The article concludes that the effectiveness of distributed water systems depends on various factors, including population density, local water demand, and infrastructure.

Clinical impact of heterogeneously distributed tumor-infiltrating lymphocytes on the prognosis of colorectal cancer

04 Apr 2024  |  peerj.com
The article discusses a medical study on the role of tumor-infiltrating lymphocytes (TILs) in colorectal cancer (CRC) patients. The study analyzed clinical, histopathologic, and immunologic variables of 78 CRC patients from the People’s Hospital of Baoan District, using statistical methods like Pearson’s χ2 test, Kaplan–Meier method, and Cox proportional hazards models. Immunohistochemistry was performed using antibodies from Abcam to assess CD3+ and CD8+ TILs. The study found that the ratio of CD3+/CD8+ TILs in the invasive margin was higher in patients with disease recurrence, suggesting that the composition of TILs is more impactful on prognosis than their absolute number. The study was approved by the ethics committee of the hospital, and it suggests that the spatial distribution and composition of TILs are heterogeneous, which may influence the prognosis of CRC patients. The study also discusses the potential of TILs as a predictive indicator for the benefit of adjuvant chemotherapy in early-stage CRC patients.
