Surface sediment in urban waterways originates from fine topsoil particles within catchments via surface erosion, often bonded with non-degradable metal(loid)s. This study posited that urban green infrastructures (UGIs) can influence anthropogenic metal(loid) transport from catchment topsoil to waterway sediment by retaining moveable particles. In multiply channeled downtown Suzhou, China, UGIs' spatial patterns were examined in relations to metal(loid)s source (catchment topsoil) - sink (waterway surface sediment) dynamics.

In this study, we investigated the effect of the pore volume and mesopore size of surface-active catalytic organosilicas on the genesis of particle-stabilized (Pickering) emulsions for the dodecanal/ethylene glycol system and their reactivity for the acid-catalyzed biphasic acetalization reaction. To this aim, we functionalized a series of fumed silica superparticles (size 100-300 nm) displaying an average mesopore size in the range of 11-14 nm and variable mesopore volume, with a similar surface density of octyl and propylsulfonic acid groups. The modified silica superparticles were characterized in detail using different techniques, including acid-base titration, thermogravimetric analysis, TEM, and dynamic light scattering.

Understanding the dynamic changes in peatland area during the Holocene is essential for unraveling the connections between northern peatland development and global carbon budgets. However, studies investigating the centennial to millennial-scale process of peatland expansion and its climate and environmental drivers are still limited. In this study, we present a reconstruction of the peatland area and lateral peatland expansion rate of a peatland complex in northern Sweden since the mid-Holocene, based on Ground Penetrating Radar measurements of peat thickness supported by radiocarbon (C) dates from four peat cores.

With a long-term amendment of manure-based organic fertilizers (MOFs), significant elevations of antibiotics and their resistance genes in agricultural soil have aroused great concerns worldwide, but their relationships to animal farming and possible environmental risks of fertilization lack systematic studies. This study collected 41 commercial MOFs made from manures of chicken, swine, sheep/goat, and cattle, respectively, in 10 provinces (including autonomous regions) of China mainland with large animal farming industries. Twenty-nine compounds, consisting of 20 antibiotic compounds, sulfonamides' synergist (trimethoprim) and 8 non-antibiotic pharmaceuticals, were quantified in the collected MOF samples, ranging from below the quantification limits (<0.

Article Synopsis
  • Urban green infrastructure successfully reduces stormwater runoff volume and pollutants, but its spatial impacts need further understanding.
  • A study in Suzhou, China, involved 144 surface water quality sampling points to assess chemical and sensory aspects, revealing significant spatial variations in water quality, with phosphorus-limited eutrophic conditions present.
  • Results indicated that green spaces, especially within a 100 m buffer along waterways and roadsides, play a crucial role in managing nutrient loads in surface water and should be prioritized in urban planning strategies.

Appropriate assessment on concerned soil contaminants spatially is of importance for decision-makers and stakeholders to make efficient mitigation countermeasures. In this study, we applied multiple geostatistical approaches to explore soil nutrient and metallic contaminant distributions in a large river watershed in Thailand, and to compare their performances in predicting spatial distribution patterns of the concerned soil contaminants under suitable application scenarios. The total carbon, nitrogen and phosphorous in surface soils over the whole watershed were measured with their maximum concentrations up to 131.

Peatlands are characterized by their large carbon storage capacity and play an essential role in the global carbon cycle. However, the future of the carbon stored in peatland ecosystems under a changing climate remains unclear. In this study, based on the eddy covariance technique, we investigated the net ecosystem CO exchange (NEE) and its controlling factors of the Hongyuan peatland, which is a part of the Ruoergai peatland on the eastern Qinghai-Tibet Plateau (QTP).

Pharmaceutical residues in river surficial sediment are prone to anthropogenic impacts and environmental factors in watershed, but the mechanisms remain unclear. This study attempted to reveal surficial sediment-water pseudo-partitioning and anthropogenic (land use) patterns of pharmaceutical residues in surficial sediment among 23 subwatersheds of Jiulong River, southeast China with a gradient of urban land use percentile in dry and wet seasons. Thirty-eight out of target 86 compounds from six-category pharmaceuticals were quantified and ranged from below the quantification limits (0.

Hsa_circ_0001947 is associated with multiple cancers, but its function in non-small cell lung cancer (NSCLC) is ambiguous and needs further research. The targeting relationship among circ_0001947, miR-661, and downstream of tyrosine kinase 7 (DOK7) was predicted by database and further verified by dual-luciferase reporter assay, while their expressions in cancer tissues and cells were detected by quantitative real-time polymerase chain reaction (qRT-PCR). After transfection, cell biological behaviors and expressions of miRNAs, miR-661 and DOK7 were determined by cell function experiments and qRT-PCR, respectively.

  • Recent research shows that oxaliplatin-resistant colorectal cancer (OR-CRC) cells have higher levels of PARP-1 binding protein (PARPBP) compared to non-resistant cells.
  • Kinesin family member 18b (KIF18b) boosts the expression of PARPBP, playing a key role in maintaining the oxaliplatin resistance in these OR-CRC cells.
  • Clinical findings indicate a correlation between high levels of KIF18b and PARPBP in CRC tissues, which is associated with a worse prognosis for patients.

Article Synopsis
  • Public concern has led to stricter regulations on antimicrobials used in aquaculture, prompting a study of tilapia feed and sediments in southern China.
  • Analysis of 86 compounds revealed that while commercial feeds were mostly tetracycline-free, they still contained other antimicrobials like quinolones and salicylic acid.
  • Sediment samples showed high levels of antibiotics and other residues, indicating that antibiotic-free feed alone may not effectively prevent antibiotic misuse in aquaculture.

Pickering emulsions offer a promising platform for conducting interfacial reactions between immiscible reagents. Despite the significant progress in the engineering of amphiphilic catalysts for such reactions, the mechanism behind their enhanced activity is still poorly understood. Herein, using the glycerol/dodecanol system as a case study, we conducted a combined meso- and microscale study of Pickering emulsions stabilized by amphiphilic silica nanoparticles bearing acid centers by marrying dissipative particle dynamics simulations with emulsification experiments.
