Insight into Nrf2: a bibliometric and visual analysis from 2000 to 2022

Global advances and innovations in bacteria-based biosorption for heavy metal remediation: a bibliometric and analytical perspective

Industrialization and urbanization have significantly escalated the discharge of heavy metals into aquatic environments, posing serious ecological and public health risks. This study explores the global research landscape of bacterial biosorption for heavy metal removal, emphasizing advancements in methodologies and technologies that have redefined this field. A bibliometric analysis of 298 publications (1987-2024) was conducted to identify key trends, collaboration networks, and innovations. Notable advancements include the integration of nanotechnology, which has enhanced adsorption efficiency and selectivity for specific metals, and genetic engineering approaches that optimize bacterial strains for higher adsorption capacity. Furthermore, these developments have transformed traditional remediation strategies by providing cost-effective, sustainable, and scalable solutions for industries such as textiles, mining, and energy production. This study underscores the practical relevance of bacterial biosorption in wastewater treatment, achieving removal efficiencies exceeding 99% in some cases, as demonstrated by Aspergillus versicolor and Shewanella oneidensis MR-1. By bridging scientific innovation with environmental sustainability, this research highlights bacterial biosorption as a pivotal green technology, offering actionable insights for industrial applications and global sustainability goals.

Research on stem cell therapy for spinal cord injury: a bibliometric and visual analysis from 2018-2023

Objectives: The aim of this study was to conduct a bibliometric analysis of the literature on stem cell treatment for spinal cord injury to gain an intuitive understanding of how the field is progressing, discover topics of interest, and determine what development trends are emerging in this field. Background: Spinal cord injury and its complications often cause an enormous economic burden, and postinjury repair and treatment have always been challenging in clinical and scientific research. Stem cell therapy for spinal cord injury can prevent immune rejection and induce the release of neuroprotective and anti-inflammatory factors to reduce the production of stress-related proteins, reactive oxygen species, and inflammatory reactions. Methods: We analyzed the number and quality of publications in the field of stem cell therapy in spinal cord injury between 2018.01.01 and 2023.06.30 in the core collection database of Web of Science. CiteSpace and VOSviewer were used to sort and summarize these studies by country, institution, authors' publications, and collaborative networks. In addition, the research topics of interest were identified and summarized. Results: This study ultimately included 2,150 valid papers, with the number of publications showing a gradual upward trend. The country, institution, author and journal with the greatest number of publications and citations are China, the Chinese Academy of Sciences, Dai JW, and the International Journal of Molecular Sciences, respectively. The top three high-frequency keyword clusters were hereditary paraplegia, reactive astrocytes and tissue engineering. Conclusion: With the help of visual analysis, we identified general trends and research topics of interest in the field of spinal cord injury over the last 5 years. Our findings suggest that stem cell transplantation for spinal cord injury and exosome therapy may be a focus of future research. This study provides a foundation for future research on stem cell therapy as well as clinical efforts in this field.
