Drug-induced liver injury (DILI) is one of the common adverse drug reactions and the leading cause of drug development attritions, black box warnings, and post-marketing withdrawals. Current biomarkers are suboptimal in detecting DILI and predicting its outcome. This study aimed to quantitatively and qualitatively investigate the research trends on DILI biomarkers using bibliometric analysis. All relevant publications were extracted from the Web of Science database. An online analysis platform of literature metrology, bibliographic item co-occurrence matrix builder, and CiteSpace software were used to analyze the publication trends. CitNetExplorer was used to construct direct citation networks and VOSviewer was used to analyze the keywords and research hotspots. We found a total of 485 publications related to DILI biomarkers published from 1991 to 2020. Toxicological Sciences had been the most popular journal in this field over the past 30 years. The USA maintained a top position worldwide and provided a pivotal influence, followed by China. Among all the institutions, the University of Liverpool was regarded as a leader for research collaboration. Moreover, Professors Paul B. Watkins and Tsuyoshi Yokoi made great achievements in topic area. We analyzed the citation networks and keywords, therefore identified five and six research hotspot clusters, respectively. We considered the publication information regarding different countries/regions, organizations, authors, journals, et al. by summarizing the literature on DILI biomarkers over the past 30 years. Notably, the subject of DILI biomarkers is an active area of research. In addition, the investigation and discovery of novel promising biomarkers such as microRNAs, keratin18, and bile acids will be future developing hotspots.

Acute lung injury (ALI) is an intractable disorder associated with macrophages. This bibliometric analysis was applied to identify the characteristics of global scientific output, the hotspots, and frontiers about macrophages in ALI over the past 10 years. We retrieved publications published from 2011 to 2020 and their recorded information from Science Citation Index Expanded (SCI-expanded) of Web of Science Core Collection (WoSCC). Bibliometrix package was used to analyze bibliometric indicators, and the VOSviewer was used to visualize the trend and hotspots of researches on macrophages in ALI. Altogether, 2,632 original articles were reviewed, and the results showed that the annual number of publications (Np) concerning the role of macrophages in ALI kept increasing over the past 10 years. China produced the most papers, the number of citations (Nc) and H-index of the USA ranked first. Shanghai Jiaotong University and INT IMMUNOPHARMACOL were the most prolific affiliation and journal, respectively. Papers published by Matute-Bello G in 2011 had the highest local citation score (LCS). Recently, the keywords “NLRP3” and “extracellular vesicles” appeared most frequently. Besides, researches on COVID-19–induced ALI related to macrophages seemed to be the hotspot recently. This bibliometric study revealed that publications related to macrophages in ALI tend to increase continuously. China was a big producer and the USA was an influential country in this field. Most studies were mainly centered on basic researches in the past decade, and pathways associated with the regulatory role of macrophages in inhibiting and attenuating ALI have become the focus of attention in more recent studies. What is more, our bibliometric analysis showed that macrophages play an important role in COVID-19–induced ALI and may be a target for the treatment of COVID-19.

The fast-growing world population places food production under enormous pressure to ensure food security. One of the most common methods to increase food production is the use of pesticides, but the continuous use thereof has numerous detrimental effects on the environment. The interest in biopesticides for a possible substitute has grown over the past two decades. To determine the research evolution of biopesticides (green pesticides), a bibliometric analysis from 1994 to 2019 was carried out. A total of 580 documents were found eligible in the Scopus database for this analysis. Parameters such as the number of articles, article citations, keywords, source impact, and countries of publication were used to analyse the documents and rank countries based on authors, productivity, article citations, and co-authorship. The analysis reveals production increased significantly from 2009 and has the most published documents in 2019 with a total of 74 articles. Asia’s most populous countries, India and China, were ranked first and second, respectively, and the USA third in terms of the most productive countries in the field of plant biopesticides. Countries in Europe and Africa however have fewer publications than expected in this field, given the fact that they are high consumers of pesticides. India, China, and the USA have 4.08%, 2.94%, and 12.5% multiple country publications (MCPs), respectively, with the USA having a stronger collaboration. Finally, there is a clear indication in this study that India and China are taking the lead in substituting synthetic pesticides with the alternative natural plant biopesticide.

Abstract Background: Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer, and it lacks an efficient target treatment. Here, we aimed to gain knowledge on the development of TNBC research and explore potential treatment strategies.Methods: We analyzed 14,389 publications on TNBC from the Web of Science (WOS) over the past 20 years, from 2000 to 2020, using bibliometric methods. We evaluated the publication tendency of TNBC and the contributions of different countries. Institutions and journals with the highest number of TNBC publications were screened. Finally, the research focus of the TNBC publications were also analyzed.Results: TNBC publications have significantly increased in the past 20 years, with elevated relative research interest (RRI). The USA has the most TNBC-related publications with high quality, and China is the country with the most rapid growth tendency in TNBC publications. The University of Texas System is the institution with the most TNBC publications. Breast Cancer Research and Treatment is the journal that published the most TNBC-related publications. The top 30 publications with high citations are also listed. The researches focusing on TNBC in the past 20 years were separated into four main clusters: tumor biology, TNBC therapies, treatment sensitivity, and gene mutations. The research focus in TNBC ranked by appearing years reflects the development of TNBC treatment strategy, showing that targeting tumor immunity is now the main focus in TNBC research. Conclusions: Using bibliometric analysis, we initially revealed the increasing interest in TNBC research and summarized the publication tendency of TNBC. We also reported focused topics screened from publications in the past 20 years, indicating the main problems and research objectives of TNBC for the first time. Immune-related topics are becoming the focus of TNBC research.

Abstract Background: There has been rapid development of migraine research in the past 20 years in China and around the world. We analyzed the development trend of migraine research, and made a bibliometric analysis on the growth trend of the total number of publications, countries, institutions, authors, cited references and keywords from 2000 to 2009 and 2010 to 2019 by applying visualization software, and constructed the relevant knowledge map, and found the trends and hot spots in the field through comparison. Methods: Retrieved the literature on migraine in the Web of Science database from 2000-2009 and 2010-2019 respectively, and then utilized CiteSpace to conduct bibliometric analysis to acquire the knowledge mapping. Results: The total number of publications each year has increased year by year, and the average annual growth rate from 2000 to 2009 was 7.999%, while from 2010 to 2019 was 5.348%, with a faster growth rate from 2000 to 2009. According to the cluster analysis of institutions, authors, cited references, and keywords, 10/11, 12/11, 12/11, and 8/9 categories were obtained from 2000 to 2009 and 2010 to 2019 respectively. The most productive countries, institutions, and authors are the USA, Albert Einstein College of Medicine, and Lipton RB from 2000 to 2009 and 2010 to 2019, whose frequency is 4274/7107, 322/592, and 279/472 respectively. However, the most important of them are Belgium/ Pakistan, Houston Headache Clin/ Amgen Inc, and Lipton RB/ Klatt J, owing to their highest centrality, they are 1.20/1.08, 1.13/1.32, and 1.22/0.89 separately. Moreover, Cited references that contributed to the most co-citations are Silberstein SD (2004)/ Bes A (2013) from 2000 to 2009 and 2010 to 2019, however, the most vital cited reference is Welch KMA (2001)/ Goadsby PJ (2017). Keywords such as migraine, headache, prevalence, and the double blind are the most frequently used. But prevalence is the crucial keyword. In the cluster analysis of institutions, authors, cited references, and keywords from 2000 to 2009 and 2010 to 2019, the more convincing research categories are potential anti-migraine agent/ chronic migration prevention, reducing headache recurrence/ following symptomatic treatment, to-left shunt/ placebo controlled phase, spectrum study/ family study hemiplegic migraine, with S values of 0.952/0.956, 0.985/0/986, 0.981/0.970 and 0.985/0.982 respectively. Furthermore, the hotspots in this field are “stimulation”, “triptan” from 2000 to 2009 and 2010 to 2019. Conclusion: Based on the bibliometric analysis in the past 20 years, the knowledge mapping of the country, institution, author, cited reference, and the keyword is gained, which has an important guiding significance for quickly and accurately positioning the trend in this field.

Abstract Early diagnosis in rotating machinery has been a challenge when looking towards the concept of intelligent machines. A crucial and critical component in these systems is the lubricated journal bearing, subjected to wear fault by abrasive removing of material in its inner wall, mainly during run-ups and run-downs. In extreme conditions, wear faults can cause unexpected shutdowns in rotating systems. Consequently, advanced condition monitoring is an essential procedure in the wear diagnosis of journal bearings. Although an increasing number of data-driven condition monitoring approaches for rotating machines have been proposed in the past decade, they mostly rely on substantial amounts of experimental data for training, which is expensive and time-consuming to obtain. The objective of this work is to develop a framework using a deep learning algorithm to classify wear faults in hydrodynamic journal bearings using simulated vibrations signals. Numerically simulated datasets under different wear severity levels and operating conditions were used to train and test the diagnostics framework. The results show that the proposed framework can be a promising tool to wear fault diagnostics in journal bearings.

Background and Aims: To evaluate endoscopic sedation research and predict research hot spots both quantitatively and qualitatively using bibliometric analysis.Methods: We extracted relevant publications from the Web of Science Core Collection (WoSCC) on 13 December 2020. We examined the retrieved data by bibliometric analysis (e.g., co-cited and cluster analysis, keyword co-occurrence) using the software CiteSpace and VOSviewer and the website of bibliometrics, the Online Analysis Platform of Literature Metrology (http://bibliometric.com/), to analyse and predict the trends and hot spots in this field.Main Results: We identified 2,879 articles and reviews on endoscopic sedation published between 2001 and 2020. Although the overall trend is increasing, with slight fluctuation in some years, there were significant increases in 2007 and 2012. In respect of the contributions on endoscopic sedation research, the United States (US) had the greatest number of publications, and it was followed by Japan and China. In addition, collaboration network analysis revealed that the most frequent collaboration was between the US and China. Six of the top ten most prolific research institutions were located in the US. The most publications on endoscopic sedation research in the past two decades were found primarily in journals on gastroenterology and hepatology. Keyword co-occurrence and co-citation cluster analysis revealed the most popular terms relating to endoscopic sedation in the manner of cluster labels; these included patient anxiety, tolerance, ketamine, propofol, hypoxia, nursing shortage, endoscopic ultrasonography, colorectal cancer, carbon dioxide insufflation, and water exchange (WE). Keyword burst detection suggested that propofol sedation, adverse event, adenoma detection rate (ADR), hypoxemia, and obesity were newly-emergent research hot spots.Conclusions: Our findings showed that hypoxia, adverse event, and ADR, along with conscious sedation and propofol sedation, have been foci of endoscopic sedation research over the past 20 years. The research focus has shifted from sedative drugs to sedative complications and endoscopy quality control, which means that there will be higher requirements and standards for sedative quality and endoscopy quality in the future.
