Mapping the knowledge domains of medical textiles: A review.

As the world's textile industry shifts towards manufacturing high value-added textile structures and products, medical textiles have drawn extensive attention from researchers and the related research field is rapidly developing in recent years. To provide readers a systematic overview of this research field, a comprehensive bibliometric analysis of scientific publications related to the field in performed and visually presented using the software CiteSpace and VOSviewer in this paper. Totally 2839 papers have been retrieved and collected from the core database of Web of Science™. First, the papers are divided into several groups and quantitatively analyzed based on the year of publication, the citations in each year, and the disciplines involved in the papers. VOSviewer is adopted to analyze the collaboration among countries, organizations, and authors in the research community as well as their research output and influence in terms of citation. Then the major journals in the field are identified through performing co-citation analysis on source journals of all references cited in the retrieved papers. In addition, the highly cited papers and their references are listed in this paper. They offer researchers a glimpse of the internal relationship of scientific literature and the dynamic structure of scientific evolution. Finally, the co-occurrence analysis of keywords is also performed using VOSviewer and CiteSpace. The connection between various disciplines in the research field is revealed, so that the scientific development history, the research hotspots, and main research directions in the field can be traced.

Textile waste water treatment: analysis of mapping knowledge domains.

Textile waste water contains dyes and chemicals that produce harmful vapors and exhaust gases, which is hazardous to the environment and public health. Therefore, it must be carefully treated before discharged. To understand the research evolution in the research area of textile waste water treatment, based on bibliometrics, an in-depth analysis of the publications and hotspots in this area was presented in this paper. For the analysis, totally 6774 papers related to the research area that are published between the year 1964 and 2023 were collected from the Web of Science Core Collection. Using CiteSpace and VOSviewer as bibliometric analysis tools, the collaboration of countries, regions, and organizations was investigated. Besides, an analysis for citation and co-citation of journals, authors, references, and co-occurrence of keywords was performed. The evolution of research hotspots in the three major research directions related to degradation, oxidation, and adsorption is also analyzed in this paper. The analysis results show that researches related to oxidation and adsorption are active in recent years, while nanocomposite adsorbents and graphene oxide are the current research hotspots.

Interaction of climate change, potentially toxic elements (PTEs), and topography on plant diversity and ecosystem functions in a high-altitude mountainous region of the Tibetan Plateau.

Potentially toxic elements (PTEs) generated from mining activities have affected ecological diversity and ecosystem functions around the world. Accurately assessing the long-term effects of PTEs is critical to classifying recoverable areas and proposing management strategies. Mining activities that shape geographical patterns of biodiversity in individual regions are increasingly understood, but the complex interactions on broad scales and in changing environments are still unclear. In this study, we developed a series of empirical models that simulate the changes in biodiversity and ecosystem functions in mine-affected regions along elevation gradients (1500-3600 m a.s.l) in the metal-rich Qilian Mountains (∼800 km) on the northeastern Tibetan Plateau (China). Our results confirmed the crucial role of PTEs dispersal, topography, and climatic heterogeneity in the diversification of plant community composition. On average, 54% of the changes in ecosystem functions were explained by the interactions among topography, climate, and PTEs. However, merely 30% of the changes were correlated with a single driver. The changes in species composition (explained variables = 94.8%) in the PTE-polluted habitats located in the warm and humid low-elevation deserts and grasslands were greater than those occurring in the dry alpine deserts and grasslands. The ecosystem functions (soil characteristics, nutrient migration, and plant biomass) experienced greater changes in the humid low-elevation grasslands and alpine deserts. Our results suggest that the processes driven by climate or other factors can result in high-altitude PTE-affected habitat facing greater threats.

Caffeoylquinic acids competitively inhibit pancreatic lipase through binding to the catalytic triad.

Caffeoylquinic acid and its isomers inhibited porcine Pancreatic Lipase (PL) activity according to a competitive mode where binding and interaction with the catalytic triad of Ser153, His264 and Asp177 simultaneously occurred. The IC50 values under which 3-caffeoylquinic acid (CQA) and its isomers 4-, 5-CQA, 3,4-, 3,5- and 4,5-diCQA inhibited half of the porcine PL activity were 1.10, 1.23, 1.24, 0.252, 0.591 and 0.502 mM, respectively. The binding affinities in the range from -8.4 to -9.5 kCal/mol were well predicted from docking, which showed a high linear correlation coefficient of 0.893 and Spearman correlation of 1.0 with log(IC50) values. Caffeoylquinic acid and its isomers were stabilized by hydrogen bond and hydrophobic interaction in the binding pocket. This finding provided molecular mechanism of coffee and other natural food or drink containing caffeoylquinic acid and its isomers against lipase activity.
