Article Synopsis
  • * Results show that following a sterile diet for 120 days leads to a significant increase in potential pathogens like Streptococcus and Lactobacillus, while beneficial bacteria decrease and the overall microbial interaction network declines.
  • * The research suggests that reverting to a normal diet can help restore gut microbiome health, pointing to the potential importance of supplementing beneficial microbes to help recover the microbiome's balance post-transplant.

Anthropogenic activities significantly impact river ecosystem nutrient fluxes and microbial metabolism. Here, we examined the seasonal and spatial variation of sediments physicochemical parameters and the associated microbiome in the Pengxi river, a representative tributary of Three Gorges Reservoir, in response to seasonal impoundment and land use change by human activities. Results revealed that seasonal impoundment and land use change enhanced total organic carbon (TOC), total nitrogen (TN) and ammonium nitrogen (NH-N) concentration in the sediment, but have different effects on sediment microbiome.

Article Synopsis
  • - Viruses play a critical role in shaping bacterial communities and the efficiency of wastewater treatment, with significant variations in their composition across different treatment units of a large-scale industrial park WWTP.
  • - Metagenomic analysis revealed that dominant viral groups include Uroviricota and Nucleocytoviricota, and their abundance is affected by environmental factors, showing a decrease in anaerobic tanks but an increase in activated sludge.
  • - The study highlights Acidobacteria as a key sensitive host for viruses in wastewater, indicating a need for further investigation into how viral communities evolve and their ecological impacts in wastewater treatment processes.

Municipal solid waste (MSW) landfills are significant sources of antibiotics. However, the effects of antibiotics on MSW decomposition process and methanogenesis during solid waste decomposition remain insufficiently characterized. This study investigated the effects of environmentally relevant concentrations (ERCs) of antibiotics (200 μg/kg for each antibiotic) on MSW decomposition and methanogenesis in bioreactors treated with and without eight antibiotics (three tetracyclines, three sulfonamides, and two macrolides).

Three Gorges Reservoir (TGR) water fluctuation creates high water level (HWL) and low water level (LWL) condition in TGR aquatic ecosystem. HWL fluies significant nutrients, mainly introducing carbon and nitrogen into the ecosystem. The nitrogen input is a concern for water quality management of TGR since the possible eutrophication caused by nitrogen spike.

Plastisphere plays crucial role in global carbon and nitrogen cycles and microplastics formation. Global Municipal Solid Waste (MSW) landfills contain 42 % plastic waste, therefore representing one of the most significant plastispheres. MSW landfills are also the third largest anthropogenic methane sources and the important anthropogenic NO source.

A municipal solid waste (MSW) landfill is a significant source of antibiotic resistance, pathogens and viruses and also a habitat for microbial consortia that perform MSW decomposition. Viruses are of great significance in ecological interactions such as MSW decomposition and antibiotic resistance gene (ARG) transmission. In this study, the viral community structure and the associated driver, the linkage of viruses and their bacterial hosts, the virus-associated ARG dissemination and virtual community function on MSW decomposition were investigated in landfill leachate from seven cities, China.

The security of medical image transmission in telemedicine is very important to patients' privacy and health. A new asymmetric medical image encryption scheme is proposed. The medical image is encrypted by two spiral phase masks (SPM) and the lower-upper decomposition with partial pivoting, where the SPM is generated from the iris, chaotic random phase mask, and amplitude truncated spiral phase transformation.

In the past two decades, miRNAs have been demonstrated to play critical roles in development and progression of malignant diseases. To identify the role and mechanism of miRNA are urgent for the application of miRNA-based therapeutics in cancers. MiR-205 is a conserved miRNA from the invertebrate to mammalian species.
