The focus of research on Agricultural Economics and Management (AEM) has been switching from developed countries to developing countries. In important international journals on AEM such as "American Journal of Agricultural Economics" and "Agricultural Economics", the research objectives mainly focus on AEM problems in developing countries, e.g. the effects of globalization and liberalization on agricultural production in developing countries, and problems in agricultural resources and environmental protections in developing countries.

The purpose of this symposium is to stimulate a dialogue among basic and clinical cancer researchers between China and other countries to speed up translation of new findings in basic cancer biology into disease prevention, diagnosis, and treatment. We hope to use this conference as a forum to create a unique opportunity for exchange in current discoveries, fostering multidisciplinary collaborations, and identification of future opportunities in cancer treatment and patient care. There will be four sessions in this symposium:展开更多

Each year in the United States, more than 500,000 men and women die from coronary artery disease (CAD). CAD results from the narrowing of blood vessels that sup- ply the heart. The blood vessels become narrow when fatty deposits build up inside the arterial wall. When the arteries become clogged, the blood flow to the myocardium is impaired and a heart attack can occur. Nuclear cardiology studies use noninvasive imaging techniques to assess myocardial blood flow.展开更多

It is currently a global health challenge.AIM This research intended to explore and analyse research trends and frontiers in this field during the last 10 years, providing new inspiration for clinical decisionmaking and scientific research.METHODS Publications on hepatic cirrhosis research were retrieved from the Web of Science Core Collection on April 4, 2021. Bibliometric visualisation was conducted through VOSviewer and CiteSpace.RESULTS The analytic research was based on original articles and reviews. A total of 7775records of hepatic cirrhosis published from 2011 to 2020 were retrieved. In the past ten years, the number of related annual publications has increased significantly, especially in the United States and China. All publications were distributed among 109 countries. The United States contributed the most(21.95%)and was consistently the leading driving force, with a solid academic reputation in this area. The University of Barcelona distributed the most related articles(177articles) and was cited the most frequently. The Journal of Hepatology ranked third in the top 10journals, which has the highest impact factor(impact factor 2019 = 20.582). Jasmohan S. Bajaj was the most productive author(72 articles). Burst keywords(e.g., sofosbuvir, burden, care, sarcopenia,chronic liver failure, human gut microbiome, and nonalcoholic fatty liver disease) and a succession of reference citation bursts have provided clues about research frontiers in recent years.CONCLUSION This study identified developing trends in the evolution of liver cirrhosis to provide new inspiration for researchers.展开更多
