Butyrate derived from intratumoral microbiome facilitates pulmonary metastasis in osteosarcoma.

Osteosarcoma, the predominant primary malignant bone tumor, has a dismal prognosis due to pulmonary metastasis, necessitating innovative strategies for early prediction and targeted therapy. While microbial metabolites such as butyrate are increasingly recognized as cancer modulators, their mechanistic involvement in osteosarcoma metastasis remains undefined. Here, we integrated multiomics integration of 16S rRNA sequencing and circulating microbial DNA (cmDNA) profiling to investigate intratumoral microbiome dynamics in osteosarcoma pulmonary metastasis.

Microneedles incorporating oridonin micelles and Cu(II)-polydopamine provide effective inflammatory regulation and antibacterial effects for the healing of infected diabetic wounds.

The persistence of non-healing diabetic wounds is frequently attributed to excessive inflammation and bacterial infections. Therefore, strategies that target the reduction of inflammation while simultaneously inhibiting bacterial proliferation may offer an effective approach to overcoming this clinical challenge. In this study, we have developed an innovative formulation of hyaluronic acid (HA)-based dissolving microneedles (Cu(II)-PDA/ORI MNs) that incorporate oridonin (ORI) and Cu(II)-PDA nanoparticles, specifically designed for the treatment of chronic wounds in diabetic murine models.

Combining Acute Kidney Injury Grading and Recovery Mode for Screening in Pediatric Liver Transplantation: A Retrospective Observational Study.

Background: A growing number of studies indicate that acute kidney injury (AKI) and the pattern of recovery after kidney injury are associated with poor outcomes for grafts and long-term renal function after liver transplantation (LT). However, few systematic studies have been conducted on the pediatric liver transplantation (PLT) population.

Materials And Methods: In this single-centered retrospective observational study, according to AKI degree and whether AKI was persistent, patients were divided into three groups: non-AKI/stage 1 AKI, stage 2/3 transient AKI, and stage 2/3 persistent AKI.

Folate alleviated skin inflammation and fibrosis resulting from impaired homocysteine metabolism.

Skin fibrosis, characterized by uncontrolled secretion of extracellular matrix (ECM) proteins such as collagen, can lead to excessive scarring and compromised tissue function. Despite the widespread occurrence of fibrotic diseases, effective therapies are lacking. Recent clinical studies have demonstrated a positive correlation between serum homocysteine (Hcy) levels and the severity of systemic sclerosis.

Exosomes Derived from Mouse Breast Carcinoma Cells Facilitate Diabetic Wound Healing.

Background: Exosomes derived from breast cancer have been reported to play a role in promoting cell proliferation, migration, and angiogenesis, which has the potential to accelerate the healing process of diabetic wounds. The aim of this investigation was to examine the function of exosomes originating from 4T1 mouse breast carcinoma cells (TEXs) in the process of diabetic wound healing.

Methods: The assessment of primary mouse skin fibroblasts cell proliferation and migration was conducted through the utilization of CCK-8 and wound healing assays, while the tube formation of HUVECs was evaluated by tube formation assay.

A pan-cancer analysis of Dyskeratosis congenita 1 (DKC1) as a prognostic biomarker.

Background: Dyskeratosis congenita 1 (DKC1), a critical component of telomerase complex, is highly expressed in a variety of human cancers. However, the association of DKC1 with cancer occurrence and development stages is not clear, making a pan-cancer analysis crucial.

Methods: We conducted a study using various bioinformatic databases such as TIMER, GEPIA, UALCAN, and KM plotter Analysis to examine the different expressions of DKC1 in multiple tissues and its correlation with pathological stages.

Synergistic wound repair effects of a composite hydrogel for delivering tumor-derived vesicles and -nitrosoglutathione.

Treating chronic wounds requires transition from proinflammatory M1 to anti-inflammatory M2 dominant macrophages. Based on the role of tumor extracellular vesicles (tEVs) in regulating the phenotypic switching from M1 to M2 macrophages, we propose that tEVs may have a beneficial impact on alleviating the overactive inflammatory microenvironment associated with refractory wounds. On the other hand, as a nitric oxide donor, -nitrosoglutathione (GSNO) can regulate inflammation, promote angiogenesis, enhance matrix deposition, and facilitate wound healing.

Correlation between color doppler flow pattern and molecular biology in elderly patients with colon cancer.

Objective: To investigate the correlation between the grade and type of color Doppler flow imaging (CDFI) and tumor-related cytokines in elderly patients with colon cancer.

Methods: Seventy-six elderly patients with colorectal cancer admitted to Zhejiang Provincial People's Hospital from July 2020 to June 2022 were selected. CDFI was used to analyze the blood flow grade and distribution type of tumor tissues, and ELISA was used to detect the levels of tumor-related cytokines in serum.

Effect of La O and CeO on anaerobic methanogenesis process: Kinetics analysis and process mechanism study.

La O and CeO , as main rare earth oxides, with unique physical and chemical properties have been widely used in catalyst and grinding industry. In this study, the effects of La O and CeO on the anaerobic process were investigated. The biological methane production tests showed that 0-0.

Water quality assessment based on Nemerow pollution index method: A case study of Heilongtan reservoir in central Sichuan province, China.

In this paper, three monitoring sections were set up in Heilongtan Reservoir, and water samples were collected in 2019, 2020, and 2021 for the determination of physical and chemical properties such as permanganate index, chemical oxygen demand, and biochemical oxygen demand (BOD5). The water quality was evaluated by the single factor pollution index method and the Nemerow pollution index method, and the temporal and spatial changes of water quality were analyzed.The single factor pollution index method determines the water quality category by identifying the single worst indicator of water quality, based on the classified water quality category.

Water quality assessment of Lugu Lake based on Nemerow pollution index method.

In this paper, three monitoring sections were set up in Lugu Lake, and water samples were collected in 2019, 2020, and 2021 for the determination of physical and chemical properties such as permanganate index, chemical oxygen demand, biochemical oxygen demand (BOD) and so on. By using the single factor pollution index method and the Nemerow pollution index method, the water quality of three monitoring sections and the whole Lugu Lake was assessed, and the temporal and spatial changes of water quality were analyzed. The findings demonstrate that Lugu Lake's overall water quality is excellent, and that it has not altered significantly in three years.

Iron-doxorubicin prodrug loaded liposome nanogenerator programs multimodal ferroptosis for efficient cancer therapy.

Ferroptosis is a new mode of cell death, which can be induced by Fenton reaction-mediated lipid peroxidation. However, the insufficient HO and high GSH in tumor cells restrict the efficiency of Fenton reaction-dependent ferroptosis. Herein, a self-supplying lipid peroxide nanoreactor was developed to co-delivery of doxorubicin (DOX), iron and unsaturated lipid for efficient ferroptosis.

Arabidopsis thaliana NOP10 is required for gametophyte formation.

The female gametophyte is crucial for sexual reproduction of higher plants, yet little is known about the molecular mechanisms underlying its development. Here, we report that Arabidopsis thaliana NOP10 (AtNOP10) is required for female gametophyte formation. AtNOP10 was expressed predominantly in the seedling and reproductive tissues, including anthers, pollen grains, and ovules.
