Deoxynivalenol-laden gut-derived extracellular vesicles impair intestinal barrier integrity via 5_19616/PPAR-γ-mediated macrophage polarization dysregulation.

Deoxynivalenol (DON), a pervasive mycotoxin contaminating crops and soil, poses significant threats to ecological security and intestinal homeostasis. While gut microbiota dysbiosis is implicated in DON-induced enterotoxicity, the engineering-driven mechanisms linking gut-derived extracellular vesicles (EVs) to environmental-host interactions remain unexplored. Here, we isolated and characterized gut-derived EVs (DON-EVs) from DON-exposed mice, employing ultracentrifugation, transmission electron microscope, nanoparticle tracking analysis, and protein marker validation.

Gallic acid pretreatment mitigates parathyroid ischemia-reperfusion injury through signaling pathway modulation.

Thyroid surgery often results in ischemia-reperfusion injury (IRI) to the parathyroid glands, yet the mechanisms underlying this and how to ameliorate IRI remain incompletely explored. Our study identifies a polyphenolic herbal extract-gallic acid (GA)-with antioxidative properties against IRI. Through flow cytometry and CCK8 assays, we investigate the protective effects of GA pretreatment on a parathyroid IRI model and decode its potential mechanisms via RNA-seq and bioinformatics analysis.

Exploring the diagnostic value of endothelial cell and angiogenesis-related genes in Hashimoto's thyroiditis based on transcriptomics and single cell RNA sequencing.

(1) BACKGROUND: Hashimoto's thyroiditis (HT) can cause angiogenesis in the thyroid gland. However, the molecular mechanism of endothelial cells and angiogenesis related genes (ARGs) has not been extensively studied in HT. (2) METHODS: The HRA001684, GSE29315 and GSE163203 datasets were included in this study.

A deep learning model for the differential diagnosis of benign and malignant salivary gland tumors based on ultrasound imaging and clinical data.

Background: The preoperative differentiation between benign parotid gland tumors (BPGTs) and malignant parotid gland tumors (MPGTs) is of great significance for therapeutic decision-making. Deep learning (DL), an artificial intelligence algorithm based on neural networks, can help overcome inconsistencies in conventional ultrasonic (CUS) examination outcomes. Therefore, as an auxiliary diagnostic tool, DL can support accurate diagnosis using massive ultrasonic (US) images.

Salvage high intensity focused ultrasound for residual or recurrent cervical cancer after definitive chemoradiotherapy.

Objective: The treatment of residual/recurrent cervical cancer within a previously irradiated area is challenging and generally associated with a poor outcome. Local treatments such as salvage surgery and re-irradiation are usually traumatic and have limited efficacy. High intensity focused ultrasound (HIFU) treatment can directly ablate solid tumors without damaging neighboring healthy tissue.

Increased sensitivity of BCR-ABL-induced B-ALL to imatinib by releasing leukemia B cell differentiation blockage.

Aims: In B cell acute lymphocytic leukemia (B-ALL), B cells are blocked mainly at the pro/pre-B phase, making them poorly responsive to imatinib. We aimed to investigate whether it was possible to promote pro/pre-B cell maturation beyond this phase and make them sensitive to imatinib treatment by overexpressing immunoregulatory tyrosine activation motif (ITAM) with BCR-ABL in a Ph+ B-ALL mouse model.

Materials & Methods: Ph+ B-ALL mouse models were induced by BCR-ABL using retroviral transduction/transplantation.

Draft genomic sequence of Armillaria gallica 012m: insights into its symbiotic relationship with Gastrodia elata.

Armillaria species (Basidiomycota, Physalacriaceae) are well known as plant pathogens related to serious root rot disease on various trees in forests and plantations. Interestingly, some Armillaria species are essential symbionts of the rare Chinese medicinal herb Gastrodia elata, a rootless and leafless orchid used for over 2000 years. In this work, an 87.

Dosimetric Comparison Between Jaw Tracking and No Jaw Tracking in Intensity-Modulated Radiation Therapy.

Purpose: This article compares the dosimetric differences between jaw tracking and no jaw tracking technique in static intensity-modulated radiation therapy plans of large and small tumors.

Methods: Eight plans with large tumor (nasopharyngeal carcinoma, volume range: 510.9 to 768.

Effect of honghua (Flos Carthami) on nitric oxide production in RAW 264.7 cells and alpha-glucosidase activity.

Objective: To study the effects of extracts from Honghua (Flos Carthami) on lipopolysaccharide induced nitric oxide (NO) production in RAW 264.7 cells and the influence of the extracts on yeast a-glucosidase activity. The total flavonoid content of the extracts was also determined.
