Biological invasion poses a significant threat to biodiversity conservation and also results in substantial economic loss including the excessive cost of management to control it. Still, its impact on plant sexual reproduction strategies remains underexplored in natural settings. We conducted a field experiment on native Phragmites australis and invasive Spartina alterniflora in Bohai Bay and assessed plant size (aboveground biomass and height) and sexual reproduction (ear biomass, reproductive allocation, etc.

have a significant regulatory effect on plant growth, but the response mechanism of functional traits to the parasitism of and the trade-off relationship between traits and hyperspectral characteristics are not clear. We investigated the functional trait response and hyperspectral characteristics of , the most common urban hedge plant in China, to the parasitism of . The results showed that the parasitism of led to the difference of leaf functional traits: the leaf thickness, stomatal density, and leaf dry matter content were significantly increased, whereas the leaf area, leaf weight, specific leaf area, chlorophyll content index, and leaf tissue density were significantly decreased.

Influenced by the interplay of global climate change and urbanization, urban plants have become increasingly homogenized in China. However, regional effects of biotic homogenization cannot be clearly explained due to the lack of continuous large-scale data. Thus, we explored the characteristics and regional effects of biotic homogenization, which not only contributes to the improvement of urban biodiversity, but also has important value for human well-being.

Ecosystem engineering, such as green roof, provides numerous key ecosystem functions dependent on both plants and environmental changes. In the recent years, global nitrogen (N) deposition has become a hot topic with the intensification of anthropogenic disturbance. However, the response of green roof ecosystems to N deposition is still not clear.

The present study aimed to investigate the antiproliferative effect of embryonic stem cell-conditioned medium (ESC-CM) on the mouse liver cancer Hepa1-6 cells . Furthermore, in order to elucidate the underlying molecular mechanism, the microRNAs (miRNAs) in ESC-CM associated with the inhibition of Hepa1-6 proliferation were identified. Following the co-culture of ESC-CM and Hepa1-6 in Transwell chambers, the proliferation, cell cycle, apoptosis and associated protein expression were determined in Hepal-6 cells.

Article Synopsis
  • * A polycaprolactone coating was added to enhance the corrosion resistance of the multilayer model, resulting in a significantly lower corrosion rate compared to traditional single-layer substrates.
  • * Testing showed that while the multilayer model has a reduced flexural modulus, it maintains more stable mechanical degradation over time compared to one-layer models.

Article Synopsis
  • A new pretreatment method is developed to reduce the electrochemical activity of magnesium alloy coatings by creating a physiological stabilization layer through localized micro-galvanic corrosion.
  • This process allows the high-activity regions of the magnesium alloy to be converted into a protective coating using hydrothermal treatment.
  • Tests showed that the treated AZ91D magnesium alloy has better corrosion resistance and that the stability-hydrothermal samples are non-toxic to human embryonic kidney (HEK) 293 cells, indicating good cell viability.

A novel method for controllable fabrication of a superhydrophobic CuO surface on AZ91D magnesium alloy is reported in this paper. Hierarchical structure composed of micro/nano-featherlike CuO was obtained by electrodeposition of Cu-Zn alloy coating and subsequently an electrochemical anodic treatment in alkaline solution. After modification with lauric acid, the surface became hydrophobicity/superhydrophobicity.
