ADAMs are members of the metzincin family of zinc-dependent metalloproteinases, which play a key role in the proteolytic degradation of the extracellular matrix to invade cells. It is well known that ADAMs are involved in regulating the invasion of trophoblast cells. But the function and underlying mechanism of ADAM7 in trophoblast cells is still unknown. ADAM7 knockdown strongly inhibited HTR-8 and B6Tert-1 cells proliferation, migration and invasion, while ADAM7 overexpression reversed. The expression of protein pro-caspase 3 and pro-caspase 9 was not affected by either ADAM7 knockdown or overexpression in HTR-8 and B6Tert-1 cells, while the expression of active-caspase 3 and active-caspase 9 was strongly increased in ADAM7 silenced cells and significant decreased in ADAM7 overexpressed cells. We also found that the phosphorylation of p38MAPK was significantly inhibited in ADAM7 silenced cells while it was significantly induced in ADAM7 overexpressed cells. Metformin HCl could reverse the inhibitory effects of ADAM7 knockdown on the p38MAPK signaling pathway and the proliferation of HTR-8 and B6Tert-1 cells. ADAM7 plays a positive role in trophoblast cells, which may be attributed to regulation of the p38MAPK signaling pathway. SIGNIFICANCE It is necessary to further study the molecular mechanism of trophoblast cells proliferation, migration and invasion, and develop a more effective treatment to preeclampsia. This research might provide a new target for further research in this area.This review explores the developments leading up to the establishment of the cell theory and cellular pathology and their subsequent refinements and applications while focusing on the individuals who have made seminal advances in the field. The links between cell biology, cell pathology and cell injury research are emphasized. Recognition also is given to the importance of technological advances in microscopy, histology, biochemical and molecular methods for discovery in cell biology and cell pathology. Particular attention is focused on the work of Rudolph Virchow and his former students in the formulation of the cell theory in biology and pathology and John F. R. Kerr and colleagues who identified and developed a comprehensive characterization of apoptosis, thereby giving impetus to the contemporary field of cell injury research. Cell injury research remains an important and fruitful field of ongoing inquiry and discovery.Atmospheric aerosols can change vegetation photosynthesis through the effects of aerosols on radiation, which will affect the peak carbon dioxide emissions and carbon neutrality at global scales. In this study, we quantify the aerosol-induced direct radiation forcing (ADRF) in China from 2001 to 2014 based on the radiation flux simulation used by the Fu-Liou radiation transfer model under with-aerosols and no-aerosols scenarios. Using the radiation simulation results, we modify the atmospheric forcing datasets to drive Community Land Model 4.5 (CLM4.5) to gain the changes in carbon fluxes in China caused by ADRF. The results show that these two models are accurate in estimating radiation (R2 = 0.78-0.88) and carbon fluxes (R2 = 0.73-0.75) in China. High levels of ADRFs were captured in China, especially with increasing diffuse fraction, resulting in the diffusing fertilization effect occurring in most areas of China. The ADRF can increase cumulative gross primary productivity (GPP) and total ecosystem respiration (ER) by 3.20 gC m-2 and 5.13 gC m-2 per year, respectively. From 2001 to 2014, the diffusing fertilization effects experienced trends of increasing first and then decreasing. However, ADRFs in some regions of China show negative effects on carbon fluxes due to vulnerable vegetation functional types and high aerosol loading. The ADRF will also enable soil temperature decreases and volumetric soil water increases, which is closely related to changes in carbon fluxes. Meanwhile, due to changes in soil water and heat conditions, N2O and CH4 production will also be disturbed, and ADRF increases the global warming potential (GWP) for both greenhouse gases. This phenomenon indicated that atmospheric aerosol pollution control is far-reaching significance for peaking carbon dioxide emissions before 2030.Groundwater is under heavily threat owing to enormous infilteration of dairy farm originated wastewater into it. The anoxic environment in the groundwater due to mixing of organic rich wastewater can produce significant alterations in the groundwater quality. It is therefore necessary to treat such wastewaters before discharging to surrounding areas. Therefore, in this study we evaluated a hybrid constructed wetland (CW) system(40 m2 area) consisting of three beds, i.e. Vertical (16 m2) - Horizontal (18 m2) - Vertical (6 m2) connected in series for the treatment of dairy farm wastewater under typical high humid climate in northern India. check details Tropical perennial plant such as Arundo donax L. was grown on both vertical beds, whereas Hibiscus esculentus L. and Solanum melongena L. were grown on the horizontal bed of the system.The average purification of TSS, BOD3, total N, and P was significant (p 0.05) as 7.0 ± 7.17, 1.9 ± 0.7, 0.72 ± 0.5 g m-2 day-1and 0.3 ± 0.2, 0.3 ± 0.2 and 0.04 ± 0.01 g m-2 day-1 respectively.The average values of total biomass content of Arundo donax L. were differed significantly and recorded as 0.31 ± 0.06, 0.43 ± 0.17, and 0.43 ± 0.16 g g-1 fresh wt. in control, VF-1, and VF-2 respectively. Therefore, the hybrid CW system can be efficiently used for the treatment of dairy farm wastewater with implications on groundwater and health. Future research may focus on performance analysis of upgraded combined anaerobic reactor and hybrid CW system planted with series of macrophytes for on-site treatment of high strength dairy farm wastewater in tropical regions.Sustainable remediation, which promotes the use of more sustainable practices during environmental clean-up activities, is an area of intense international development. While numerous indicators related to sustainable remediation assessment have been utilized and published in related academic literature, they are difficult to unify and vary in emphasis between countries. Following literature retrieval from CNKI, Springer, ScienceDirect, and Wiley Online databases, we present a systematic and bibliometric analysis of relevant national and international literature to define the most frequently considered indicators of sustainability, which play important roles in selecting remediation technologies or site management methods from a sustainability perspective. Following the application of co-occurrence analysis and social network analysis, the results indicate that 1) environmental criteria are most commonly used in evaluating remediation technologies, with significantly less emphasis on social criteria in Chinese publications in particular; 2) with an increasing number of publications in the last 20 years, sustainable remediation has gone through an initial stage, rising stage, and burst or wider adoption stage, characterized by a transformation of the research theme from a predominantly risk-based management approach to a sustainability-based one, with risk management as an underpinning principle; 3) health, resource, cost, and time are the most widely used indicators in terms of social, environmental, economic, and technical criteria, respectively; 4) clear differences exist between China and other nations, particularly in the frequency of usage of each indicator, the application of social criteria, and preferred stakeholders.
