Background: Arsenic trioxide (As2O3) has a dramatic therapeutic effect on acute promyelocytic leukemia (APL) patients. It can also cause apoptosis in various tumor cells. This study investigated whether As2O3 has an antitumor effect on glioma and explored the underlying mechanism. Results: MTT and trypan blue assays showed that As2O3 remarkably inhibited growth of C6 and 9 L glioma cells. Cell viability...
Biochar’s production and application in soils has been suggested as a means of abating climate change by sequestering carbon while simultaneously providing energy and increasing crop yields. However, little is known about biochar’s effect on nitrification in alkaline soil. This study focused on the effect of wheat straw-derived biochar (0%, 2%, 5%, and 10%, w/w) on nitrification in a calcareous clay...
Fly ash and ground iron ore tailings with fineness similar to cement were used as active and inert mineral admixtures in this study. This paper examines the compressive strength development of plain mortar and blend mortar containing fly ash and ground iron ore tailing. The mortar was cured at the same curing regime and a different water to cementitious material ratio was used. The autogenous shrinkage...
A new cytoplasmic small heat shock protein gene was cloned from Pinellia ternata (Thunb.) Breit and designated PtHSP18.2 (GenBank number: KF693218). The PtHSP18.2 gene has an open reading frame of 711 bp that encodes 159 amino acids, and a molecular mass of 18.20 kDa. The phylogenetic tree indicated high homology of the PtHSP18.2 protein with that of cytosolic class I small heat shock proteins (CI...
Aerobic anoxygenic phototrophic (AAP) bacteria are known functionally as photoheterotrophic microbes. Though numerously reported from ocean habitats, their distribution in freshwater lakes is far less documented. In the present study we investigated the dynamics of AAP bacteria in freshwater plateau lakes. Results revealed a high abundance of AAP bacteria in eutrophic lakes. Moreover, AAP bacteria...
In order to improve the utilization of the steelmaking byproduct steel slag in the concrete industry, this paper mainly studied the cementitious and hydration properties of converter steel slag. X-ray diffraction (XRD), non-evaporable water amount, strength, and particle size distribution were measured and analyzed. The paste with steel slag and water can be slowly hardened, which indicates the weak...
In this paper, a comprehensive research of the evolution of the hierarchical structure and spatial pattern of coastal cities in China was conducted based on the data of distribution of the headquarters and subsidiaries of marine-related enterprises in 1995, 2005 and 2015 using the city network research method proposed by Taylor. The results of the empirical research showed: China’s coastal city network...
In the present study, the Eastern Star ferry accident was analyzed via 24Model. 24Model, as an accident causation model based on system thinking, holds that all causations of the accident are hazards and all hazards in the system need to be identified and comprehensively controlled in accident prevention. The result showed that five factors were the main causes of the accident. First, the direct causes:...
Occurrences of harmful cyanobacterial blooms are a worldwide environmental problem in most eutrophic lake ecosystems. But what should be noticed is that cyanobacteria can be used as a useful resource due to the wide range of metabolites they produce. Nutrient partitioning using purple nonsulfur bacteria (PNSB) has the potential to biologically concentrate nutrients. The present study evaluated the...
Intense marine reclamation activities bring obvious benefits, meanwhile, these activities also influence the coastal natural formation, hydrodynamic processes and water environment etc. In order to investigate the exact influence in the Qinzhou Bay brought by marine reclamation behaviors in recent years, based on the remote sensing image data in the Qinzhou Bay in 2006, 2008, 2009, 2012 and 2014,...
To achieve emission reduction targets in China, it is necessary to analyze the factors driving energyrelated carbon emissions from a regional perspective. We used extended STIRPAT model (stochastic impacts by regression on population, affluence, and technology) based on the classical IPAT identity (where I = impact representing carbon emissions, P = population, A = affluence, and T = emission intensity)...
Controlling carbon emissions without impairing urbanization and economic development highlights the necessity of researching energy-related carbon emissions. Urban areas have become the main source of energy consumption and carbon emissions. This paper has developed a modified version of the Kaya identity, which incorporates urbanization and resident consumption, to analyze urbanization effect on...
Heat stress is a major environmental stress that limits plant growth and yield worldwide. The present study was carried out to explore the physiological mechanism of heat tolerant to provide the theoretical basis for heat-tolerant breeding. The changes of leaf morphology, anatomy, nitrogen assimilation, and carbohydrate metabolism in two wucai genotypes (WS-1, heat tolerant; WS-6, heat sensitive)...
This study aims to determine the functional traits and reproductive allocation (RA) strategy of the invasive plant Conyza canadensis across different invasion degrees along a latitude gradient in China. Invasion degree did not affect the functional traits and RA strategy of C. canadensis significantly. The high proportion of reproductive biomass (allocating approximately 20% of total biomass into...
