Zusammenfassung Die nekrotisierende Fasziitis ist eine fulminant verlaufende, potenziell lebensbedrohliche Infektion des Haut- und Weichteilgewebes. Sie wird meist durch eine Kombination unterschiedlicher Bakterien verursacht und ist häufig auf vermeintliche Bagatelltraumata zurückzuführen. Klinisch zeigen sich initial wenig eindrückliche Hautveränderungen wie Blasenbildung oder Rötung. Diese werden häufig von übermäßig stark erscheinenden Schmerzen begleitet. Im weiteren Verlauf...

Abstract Anthropogenic activities have caused extensive arsenic (As) contamination in soils. The role of biochar in the remediation of As-contaminated soils has been attracting attention lately. In this study, effects of straw biochar, iron oxide, and iron oxide–modified biochar on soil microbial community composition and soil chemical properties were tested in an As-contaminated soil. After 9 months of incubation, soil chemical properties and microbial communities were analyzed....

Abstract Ecosystems play critically important roles in supporting human society, while human activities seriously disturb their initial balance. Lots of researches on ecosystem services are conducted due to the increasing concern on ecological security worldwide. In order to provide valuable insights for understanding the primary performance of ecosystem services–related studies, a qualitative and quantitative analysis by using a bibliometric tool is performed in this study.

Abstract Cadmium (Cd) availability in arable soils is a serious issue while little is known about the role of co-composted organic amendments and zinc oxide nanoparticles (ZnO-NPs) foliar spray on biomass and Cd accumulation in wheat grains. The current study investigated the soil application of organic amendment (composted biochar and farmyard manure) at a level of 0, 1, and 2% w/w and foliar spray of ZnO-NPs (0, 100, and 200 mg/L) on biomass, yield, and Cd in wheat grains cultivated...

Abstract To examine the status and risk of heavy metal pollution in an urban wetland in China, the distribution and speciation of chromium (Cr) and other metals (Cd, Cu, Pb, and Zn) were examined. We investigated the impact of three major land uses (residential and industrial (RI), orange plantation (OP), and mixed OP and RI (OPRI)) on the heavy metal characteristics using sediment cores (0–60 cm below water/sediment interface) collected in Sanyang Wetland, China. It was found...

Abstract Previously, we demonstrated that maternal exposure to high, intermediate, or lowly contaminated European eels with a mixture of chemicals, during pregnancy and lactation, resulted in adult despair-like behavior, selectively in male offspring mice. Here, we investigate if depression-like behavior in offspring males was transient or permanent by monitoring immobility behavior, a measure of behavioral despair, at three distinct stages of life, including young adult (post-natal...

Abstract This study set out to reveal to what extent women entrepreneurs operating in rural areas have been affected by environmental pollution and climate change. Besides, it emphasises how much they will be affected over the next 5 years throughout Turkey. The study covered rural areas of all seven regions in Turkey. Findings were analysed by using SPSS 23 programme. Women entrepreneurs were younger in less developed regions of the country, such as the Central, Eastern, and South-Eastern...

Abstract The cadmium (Cd) is considered one of the widespread toxic metals in the aquatic and terrestrial environments, which is due to its long half-life, non-degradable characteristic, and toxicity. Aqueous extract of freeze-dried Moringa oleifera (Moringaceae family) leaves was examined for protective effect and antioxidant power against Cd toxicity. The results revealed that Moringa aqueous extract (MAE) has contents of total polyphenols and flavonoids about 30.14 mg GAE/g...

Abstract Environment-economic growth nexus is one of the main concerns of the researchers in the modern era. Although there are several studies in this field, discussions are far from being reached a consensus. The main purpose of this study is to investigate the role of economic growth, renewable and non-renewable energy consumption, oil prices, and trade openness on CO2 emissions in 25 Organization for Economic Co-operation and Development (OECD) countries over the period 1990–2014....

Abstract Dust particles suspended in the atmosphere have been a big headache for electric power transmission industry in China. As transmission lines pass through dusty or air-polluted areas, dust contaminants are likely to deposit and accumulate on line insulators, which is one of the greatest causes of flashover and failure of power transmission. To study the statistical characteristics of this type of contamination, dust samples were collected and measured, and a physical model...

Abstract Low-value solid waste cordierite honeycomb ceramics were used as carrier of SCO denitration catalyst, and the active component was supported by the impregnation method to improve the performance of the catalyst. Firstly, the effect of calcination conditions on the denitration performance of the Mn-loaded cordierite catalyst was studied for the cordierite-loaded active component MnOX. Secondly, the preferred catalyst was reloaded with another active component to further...

Abstract Dengue is the most important infectious disease in the world and is a severe public health problem. The chikungunya is an arbovirus, in many cases, increased, which is transmitted by the same transmitter dengue vector, Aedes aegypti. The symptoms of both diseases are similar, and infections can be lethal. Although there is no preventive vaccine against any of the two diseases, therefore, it is extremely important to control the mosquito. The eggs of A. aegypti are very...

Abstract To figure out which factor contributes more on carbon emissions caused by energy consumption, this research took multisector analysis based on the Log-Mean Divisia Index Method (LMDI) and decoupling theory to assess the driving factors of carbon dioxide (CO2) emissions in China’s six sectors from 2003 to 2016. Our empirical results reveal that China’s economy can be divided as three decoupling stages and exhibited a distinct tendency toward strong decoupling with a turning...

Abstract This study calculates the green investment level of each province in China and objectively estimates the provincial environmental regulation level from the perspective of the government to examine the effectiveness and impact of the government’s environmental protection policy on the environmental regulation level. The carbon emission trading pilot policy is determined through a quasi-natural experiment difference in difference model to examine the impact and assess the...

Abstract Background When children with attention-deficit/hyperactivity disorder (ADHD) are treated with stimulant medication, the dose is established clinically by dose adjustment over time. Little is known about children who are not adequately treated when they reach a designated maximum dose, or the consequences of exceeding this dose. Objective The aim...
