ReviewMapping the research of energy subsidies: a bibliometric analysis.
A review of energy subsidy research from a bibliometric perspective was conducted. Based on the bibliometric method, a statistical analysis of energy subsidy-related publications from 1997 to 2016 was undertaken using the Science Citation Index (SCI) and Social Science Citation Index (SSCI) databases. A total of 1182 publications were retrieved, with a significant increase in the number of publications observed after 2006. ⋯ However, the institute-keyword 2-mode network showed that institutes had great potential to cooperate on a number of common topics. Five major themes were identified from the co-keywords analysis: general renewable energy research, bio-energies, sustainability, subsidies, and welfare. The findings, as a complement to previous conventional reviews, will be useful in future energy subsidy research.

Influence of ferulic acid consumption in ameliorating the cadmium-induced liver and renal oxidative damage in rats.
The aim of this study relates to the modulatory role of ferulic acid (FA) against cadmium (Cd)-induced oxidative stress in the liver and kidney of male Wistar albino rats. Cd is an extremely toxic industrial and environmental pollutant and is well known for its varied toxic clinical manifestations. FA is a derivative of curcumin and a ubiquitous phenolic compound having a wide range of therapeutic activities. ⋯ But, FA significantly reduced the toxicity of Cd and protected the normal histological architecture of the liver and kidney tissues. Cd-intoxicated rats were associated with a significant upregulation of TNF-α, COX-2, and HSP70 proteins, whereas treatment with FA caused downregulation of the above inflammatory markers indicating the anti-inflammatory role of FA. Principal component analysis (PCA) and Euclidean similarity measure studies clearly indicate that the liver is more prone to Cd toxicity than the kidney and FA supplementation significantly prevents oxidative stress, augmenting antioxidative status, and regaining histological parameters of the liver and kidney to normal, indicating hepato-nephroprotective, antiradical, antioxidant, and anti-inflammatory effects of this phenolic compound.

Global trends and future prospects of e-waste research: a bibliometric analysis.
Electronic waste (e-waste) has been widely studied by scholars all over the world, but the research topics and development trends in this field are still unclear. This study aimed to explore the status quo, hot topics, and future prospects in the field of e-waste. Data of publications were downloaded from the Web of Science Core Collection. ⋯ The Waste Management (225 publications) was the most productive journal, and Environment Science & Technology (9704 co-citations) was the most co-cited journal. The main hot topics in e-waste field were management and recycling of e-waste in developing countries, health risk assessment after exposure to organic pollutants, degradation and recovery of waste metal materials, and impact of heavy metals on children's health. The frontier topic was degradation.

Dynamic linkages among CO2 emissions, health expenditures, and economic growth: empirical evidence from Pakistan.
The linkage between high concentration of greenhouse gases (GHGs) and climate change is well recognized as there is severe influence of climate change on public health. Carbon dioxide is most prominent GHG which deteriorates the environment and impacts human health. On the parallel, economic growth also affects health conditions sometimes positively or vice versa. ⋯ The bidirectional causal relationship is also investigated between carbon emissions and growth as well as gross fixed capital formation and growth. Then, policy recommendations towards controlling pollution, particularly CO2 emissions and health expenditures without compromising economic growth are suggested. Graphical abstract .

Natural disasters, climate change, and their impact on inclusive wealth in G20 countries.
This paper uses the 1990-2010 natural disaster and carbon emission data of G20 countries to examine the impact of natural disasters and climate change on the natural capital component of inclusive wealth. Our study shows that climate change and GDP have no positive impacts on the growth of natural capital. ⋯ Natural capital growth is not affected very much by small disasters. By contrast, large disasters tend to make the growth of natural capital fall sharply.
