Abstract Recent advances highlight the role of gut virome, particularly phageome, in metabolic disorders such as obesity, type 2 diabetes mellitus, metabolic dysfunction‐associated fatty liver disease, and cardiovascular diseases, including hypertension, stroke, coronary heart disease, and hyperlipidemia. While alterations in gut bacteria are well‐documented, emerging evidence suggests that changes in gut viruses also contribute to these disorders. Bacteriophages, the most abundant gut viruses, influence bacterial populations through their lytic and lysogenic cycles, potentially modulating the gut ecosystem and metabolic pathways. Phage therapy, previously overshadowed by antibiotics, is experiencing renewed interest due to rising antibiotic resistance. It offers a novel approach to precisely edit the gut microbiota, with promising applications in metabolic diseases. In this review, we summarize recent discoveries about gut virome in metabolic disease patients, review preclinical and clinical studies of phage therapy on metabolic diseases as well as the breakthroughs and currently faced problems and concerns.

Natural water pollution and eutrophication are environmental problems that urgently need to be solved. Porous ceramsite could be applied for both water storage and water purification. This research used biomass and dredged silt to prepare water storage ceramsite (WSC), and investigated the adsorption and removal effects of WSC on phosphorus (P), nitrogen ((NH 4+ )N) and chemical oxygen demand (COD). The results showed that the biomass was mostly burned and partially carbonized during the high-temperature sintering process to form a rich pore structure inside the material. The rich pore structure effectively improved the water absorption to 105.58 %. The abundant specific surface area could provide many attachment sites, which is conducive to the adsorption of target ions by WSC. Further testing showed that WSC could adsorb ions with different charges in different pH solutions. Therefore, this study provides a sustainable solution for the co-utilization of biomass waste and dredged silt, and the application of WSC could reduce the damage caused by extreme rainfall and water pollution., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier B.V.
