AI Article Synopsis
Article Abstract
Employing high-throughput sequencing as the method, this study analyzed the relationship between the water environment and the microbial community structure in the surface-flow constructed wetland. The results showed that: the mean Shannon-Wiener index was 6.57 and there were mainly 18 categories in the microbial community, including Proteobacterice (38.97%), Bacteroidetes (15.63%) etc. Of these, the total content of 22 genera was over 1%. The microbial biodiversity showed an increasing trend at the beginning and then turned to a decreasing trend in the flowing direction. The results also revealed that pH, ORP, NH-N, NO-N and TN acted as important restricting factors for the microbial community.

Hypertension, commonly known as high blood pressure, is a significant health issue that increases the risk of cardiovascular diseases, stroke, and renal failure. This condition broadly encompasses both primary and secondary forms. Despite extensive research, the underlying mechanisms of systemic arterial hypertension-particularly primary hypertension, which has no identifiable cause and is affected by genetic and lifestyle agents-remain complex and not fully understood.

The plastisphere, defined as the ecological niche for microbial colonization of plastic debris, has been recognized as a hotspot of pathogenic and antibiotic-resistant bacteria. However, the interactions between bacteria and phages facilitated by the plastisphere, as well as their impact on microbial risks to public health, remain unclear. Here, we analyzed public metagenomic data from 180 plastisphere and environmental samples, stemming from four different habitats and two plastic types (biodegradable and nonbiodegradable plastics) and obtained 611 nonredundant metagenome-assembled genomes (MAGs) and 4061 nonredundant phage contigs.

It was previously reported that utilization of tetrathionate and 1,2-propanediol by spp. through the metabolic pathways encoded by and operons are related to overgrowth and out-competing microbiota in an anaerobic environment. However, recent knowledge demonstrated which strains in the absence of and genes provoke both higher intestinal colonization and spreading bacteria on faeces in relation to their respective wild-type strain, and generate more prominent inflammation as well.

The gut microbiome, which is composed of bacteria, viruses, and fungi, and is involved in multiple essential physiological processes, changes measurably as a person ages, and can be associated with negative health outcomes. Microbiome transplants have been proposed as a method to improve gut function and reduce or reverse multiple disorders, including age-related diseases. Here, we take advantage of the laboratory model organism, Drosophila melanogaster, to test the effects of transplanting the microbiome of a young fly into middle-aged flies, across multiple genetic backgrounds and both sexes, to test whether age-related lifespan could be increased, and late-life physical health declines mitigated.
