Precise manipulation of pore sizes in Zr(IV)-Based metal-organic frameworks for enhanced bisphenol a removal from water.

Metal-organic frameworks (MOFs) recently gained immense popularity for the adsorption of organic impurities. In this work, the adsorptive separation of bisphenol A (BPA) from aqueous mixtures was explored utilizing three types of zirconium-based MOFs, namely MOF-808, UiO-66, and hierarchically porous UiO-66 (HP-UiO-66). The HP-UiO-66, which was etched by sodium acetate as the terminal ligand, generated large mesopores ranging from 40 to 300 Å due to the departure of partial linkers and metallic clusters.

Pollution characteristics of soil heavy metals around two typical copper mining and beneficiation enterprises in Northwest China.

In order to investigate the situation of heavy metal pollution in the heavy metal industry in Gansu Province, a large copper mining province, two large and typical copper mining and beneficiation enterprises with differences in topographic features, climatic conditions, and soil types were selected as the target of this study based on similar ore types and beneficiation processes. Around these two enterprises, geochemical baselines of the six heavy metals were established, while the degree of local soil heavy metal pollution and potential hazards to humans were assessed based on statistical analysis, single-factor and multi-factor index analysis, and health risk evaluation models. In addition, Spearman's correlation analysis and hierarchical cluster analysis were used to explore the intrinsic association between each heavy metal in the two mining industries to reveal the pattern of soil heavy metal pollution in the copper mining and beneficiation industry and to propose targeted measures to improve and prevent soil heavy metal pollution.

Mapping QTL for Adult-Plant Resistance to Stripe Rust in a Chinese Wheat Landrace.

Wheat stripe (yellow) rust is a worldwide disease that seriously reduces wheat grain yield and quality. Adult-plant resistance (APR) to stripe rust is generally more durable but usually controlled by multiple genes with partial resistance. In this study, a recombinant inbred line population was developed from a cross between a Chinese wheat landrace, Tutoumai, with APR to stripe rust, and a highly susceptible wheat cultivar, Siyang 936.

Characterization of Two Wheat- Introgression Lines With Pyramiding Resistance to Powdery Mildew.

Powdery mildew is one of the most devastating foliar diseases in wheat production. The wild relative (2 = 10 = 70) has been widely used in wheat genetic improvement due to its superior resistance to both biotic and abiotic stresses. In the present study, two wheat- introgression lines named SN0293-2 and SN0293-7 were developed from the progenies of a cross between the octoploid SNTE20 and common wheat, including the elite cultivar Jimai 22.

The brassinosteroid biosynthesis gene TaD11-2A controls grain size and its elite haplotype improves wheat grain yields.

TaD11-2A affects grain size and root length and its natural variations are associated with significant differences in yield-related traits in wheat. Brassinosteroids (BRs) control many important agronomic traits and therefore the manipulation of BR components could improve crop productivity and performance. However, the potential effects of BR-related genes on yield-related traits and stress tolerance in wheat (Triticum aestivum L.

Powdery mildew, caused by f. sp. (), is a devastating fungal disease that seriously damages the yield and quality of wheat in many regions of the world.

Probabilistic risk assessment of heavy metals in urban farmland soils of a typical oasis city in northwest China.

Previous studies lacked quantitative evaluation studies of the probability of ecology and human health risks from soil heavy metals. This study assessed heavy metal risk level by collecting topsoil samples from a typical oasis city (Wuwei) in northwest China and then quantitatively evaluating the ecological risk from heavy metals by incorporating the uncertainty of health risk model parameters into the risk assessment. This study found that anthropogenic activities have influenced the accumulation of heavy metals in the study area and that the risk of contamination of soil heavy metals was characterized as light to moderate contamination and low ecological risk.

The Zinc and Iron Binuclear Transport Center of ZupT, a ZIP Transporter from .

ZupT fromis a member of the Zrt-/Irt-like Protein (ZIP) transporter family, which is responsible for zinc uptake during zinc-sufficient conditions. ZIP transporters have been shown to transport different divalent metal ions including zinc, iron, manganese, and cadmium. In this study, we show that ZupT has an asymmetric binuclear metal center in the transmembrane domain; one metal-binding site, M1, binds zinc, cadmium, and iron, while the other, M2, binds iron only and with higher affinity than M1.

Persistent Homology-Based Topological Analysis on the Gestalt Patterns during Human Brain Cognition Process.

The neuropsychological characteristics inside the brain are still not sufficiently understood in previous Gestalt psychological analyses. In particular, the extraction and analysis of human brain consciousness information itself have not received enough attention for the time being. In this paper, we aim to investigate the features of EEG signals from different conscious thoughts.

Heavy metal pollution levels, source apportionment and risk assessment in dust storms in key cities in Northwest China.

In this study, the potential hazards of heavy metals in dust storms were investigated by collecting dust storm samples, measuring their heavy metal concentrations, and using index evaluation, spatial analysis, positive matrix factorization (PMF) model and risk assessment model. Heavy metals in dust storms were contaminated by anthropogenic sources leading to their concentrations being higher than the background values. The enrichment factors and geoaccumulation indices showed that the heavy metals came from both natural and anthropogenic sources, Cu, Ni, Zn and Pb are strongly influenced by anthropogenic sources.

Curcumin Improves Human Umbilical Cord-Derived Mesenchymal Stem Cell Survival via ERK1/2 Signaling and Promotes Motor Outcomes After Spinal Cord Injury.

Human umbilical cord-derived mesenchymal stem cell (hUC-MSC) transplantation is thought to be a promising strategy for treating spinal cord injury (SCI). However, the low survival rate of transplanted hUC-MSCs limits their clinical application in cell replacement therapy. Curcumin can suppress inflammation after SCI; however, it remains unknown whether curcumin can modulate the survival of transplanted hUC-MSCs.
