Microcosm experiments deciphered resistome coalescence, risks and source-sink relationship of antibiotic resistance in the soil irrigated with reclaimed water.

Reclaimed water is widely used in agriculture irrigation to alleviate water scarcity, whereas the dissemination of antibiotic resistance genes (ARGs) in the soil it introduces has attracted widespread attention. Currently, few studies have systematically elucidated the coalescence of the resistome originating from reclaimed water with the soil's native community. Also, the effects and mechanisms of irrigation on the dissemination of ARGs in soils have yet to be demonstrated.

Temozolomide monotherapy versus combination therapies in melanoma: a meta-analysis of efficacy and safety.

Temozolomide is used in melanoma therapy, but the comparative efficacy and safety of monotherapy vs combination therapies are unclear. This meta-analysis evaluates temozolomide monotherapy vs combination therapies in melanoma patients. PubMed, Embase, and Cochrane Library were searched up to August 2024 for studies comparing temozolomide monotherapy with combination therapies in melanoma.

Microvesicles derived from mesenchymal stem cells: A promising therapeutic strategy for acute respiratory distress syndrome-related pulmonary fibrosis?

Pulmonary fibrosis significantly contributes to the pathogenesis of acute respiratory distress syndrome (ARDS), markedly increasing patient mortality. Despite the established anti-fibrotic effects of mesenchymal stem cells (MSCs), numerous challenges hinder their clinical application. A recent study demonstrated that microvesicles (MVs) from MSCs (MSC-MVs) could attenuate ARDS-related pulmonary fibrosis and enhance lung function hepatocyte growth factor mRNA transcription.

Facilitation of Tumor Stroma-Targeted Therapy: Model Difficulty and Co-Culture Organoid Method.

Tumors, as intricate ecosystems, comprise oncocytes and the highly dynamic tumor stroma. Tumor stroma, representing the non-cancerous and non-cellular composition of the tumor microenvironment (TME), plays a crucial role in oncogenesis and progression, through its interactions with biological, chemical, and mechanical signals. This review aims to analyze the challenges of stroma mimicry models, and highlight advanced personalized co-culture approaches for recapitulating tumor stroma using patient-derived tumor organoids (PDTOs).

[One-stage mandibular reconstruction combining iliac flap with immediate implant-based denture].

Objective: To evaluate the clinical outcomes and define the indications for a one-stage mandibular reconstruction technique that combines iliac bone flaps with immediate implant-based dentures, and to assess both the accuracy of surgical planning and the long-term success of the procedure.

Methods: A total of ten patients underwent the procedure at Peking University Hospital of Stomatology between June 2020 and August 2023. The preoperative biopsy pathology of all the patients confirmed a benign tumor.
