Improvement effect of Biluochun tea active extract on CCl-induced acute liver injury.

Biluochun tea is reported to have antioxidant and anti-inflammatory properties, while its effect on liver disease remains unknown. In this study, a CCl-induced acute liver injury mouse model with five experimental groups (normal control group, CCl group, low-dose Biluochun tea group, high-dose Biluochun tea group, and silymarin positive control group) were established to evaluate the hepatoprotective effects of Biluochun bioactive extract. Furthermore, high-performance liquid chromatography (HPLC) was utilized for qualitative analysis of the major bioactive components in the extract.

Starting the Engine and Releasing the Brakes of T-Cell Responses: A Biomimetic Dendritic Cell Nanoplatform for Improved Glioblastoma Immunotherapy.

Glioblastoma (GBM), the most aggressive primary brain tumor, remains a challenge for immunotherapies, like immune checkpoint blockade (ICB), due to the blood-brain barrier (BBB) and immunosuppressive tumor microenvironment (TME) deficient in cytotoxic T-cells and effective T-cell-dendritic cell (DC) interactions. Herein, we engineer a biomimetic nanoplatform comprising paclitaxel (PTX) nanoparticles (NPs) encapsulated in a tumor-associated antigen-loaded DC membrane modified with ICB antibodies. The DC membrane not only facilitates BBB penetration and GBM targeting but also directly engages with T-cells reminiscent of T-cell-antigen-presenting cell (APC) clusters.

Paracrine signaling of ferroptotic airway epithelium in crystalline silica-induced pulmonary fibrosis augments local fibroblast activation through glycolysis reprogramming.

Chronic exposure to crystalline silica (CS) contributes to pulmonary fibrosis. Airway epithelium dysfunction and fibroblast activation have both been recognized as pivotal players, alongside disturbances in ferroptosis and glycolysis reprogramming. However, the mechanisms involved remain unclear.

Protective effect of Dunn extract on oxidative damage of LLC‑PK1 cells induced by HO.

Dunn extract (PPDE) is a well-known treatment used in traditional Chinese medicines, where it is most commonly used to treat coughs and symptoms such as headaches and fever. In the present study, the antioxidant capacity of PPDE was determined by scavenging experiments using DPPH, ABTS·, ·OH, and ·O. The cell survival rate was determined by MTT assay.

[Bioinformatics Analysis of Hub Genes of Diabetic Foot Ulcer and Their Biofunctions].

Objective: To explore the hub genes associated with the pathogenesis and healing of diabetic foot ulcer (DFU) and their biological functions through bioinformatics analysis of transcriptome sequencing data.

Methods: The transcriptome sequencing datasets of DFU were selected from Gene Expression Omnibus (GEO) database, and the data were regrouped and normalized for bioinformatics analysis. The skin transcriptome sequencing datasets of DFU patients were compared with those of normal controls and the transcriptome sequencing datasets of skin from ulcerous wound edge of DFU patients were compared with those of non-ulcerous skin of DFU patients so that differentially expressed genes were identified, pathway enrichment and protein-to-protein interaction (PPI) analyses were performed, hub genes were found through nodal analysis, and receiver operating characteristic (ROC) curve was applied to a testing dataset to validate the diagnostic efficiency of the hub genes related to DFU.

Association between depressive symptoms in the postpartum period and COVID-19: A meta-analysis.

Background: With the pandemic of COVID, the public are faced with tremendous threatens both physically and mentally. Postpartum depression (PPD) is one of the most serious complications of childbearing, bringing severe impact on a woman's mental state and mood after birth. Research has shown that maternal mental state is closely correlated with PPD, those undergo the emergency or significant life changes during the postpartum period are more likely to suffer from PPD.

Inhibitory Effect of subsp. KSFY07 on Kappa-Carrageenan-Induced Thrombosis in Mice and the Regulation of Oxidative Damage.

A mouse thrombosis model was established by kappa-carrageenan to observe the inhibitory effect of subsp. KSFY07 (LDSB-KSFY07) on thrombosis and the oxidative stress response. Mouse serum, liver tissue-related indicators, and intestinal microbial composition were measured by examining the expression of microbes in mouse faeces using a biochemical kit, slice observations, and quantitative polymerase chain reaction (qPCR) experiments.

STAT6 inhibits ferroptosis and alleviates acute lung injury via regulating P53/SLC7A11 pathway.

Compelling evidences have revealed the emerging role of ferroptosis in the pathophysiological process of acute lung injury (ALI), but its modulation is not clear. Here, we identified that STAT6 acted as a critical regulator of epithelium ferroptosis during ALI. Firstly, STAT6 expression and activity were increased in the ALI mice models caused by crystalline silica (CS), LPS and X-ray exposure.

Preventive effect of Lactobacillus plantarum HFY15 on carbon tetrachloride (CCl )-induced acute liver injury in mice.

Carbon tetrachloride (CCl ) is the main chemical causing liver damage. In this experiment, the effect of Lactobacillus plantarum HFY15 treatment on CCl -induced acute liver injury was investigated using mice. Fifty adult mice were randomized into five study groups, each group with 10 ml kg saline, 50 mg kg silymarin, and 10 CFU kg L.

Effect of monocarboxylate transporter-1 on the biological behavior of iodine-refractory thyroid carcinoma.

Background: Differentiated thyroid cancer (DTC) is the most common thyroid tumor, and the cells of DTC patients can lose the ability to differentiate in their natural state or during treatment and develop radioiodine-refractory DTC (RAI-R DTC), resulting in increased malignancy. Monocarboxylate transporter-1 ( ) is positively correlated with the level of malignant of various tumors, and its expression in RAI-R DTC cells is correlated with their biological cell traits.

Methods: Data from 14 iodine-refractory thyroid carcinoma patients were collected, and the effective radioiodine treatment group was used as the control group.

STAT6/VDR Axis Mitigates Lung Inflammatory Injury by Promoting Nrf2 Signaling Pathway.

Lung inflammatory injury is a global public health concern. It is characterized by infiltration of diverse inflammatory cells and thickening of pulmonary septum along with oxidative stress to airway epithelial cells. STAT6 is a nuclear transcription factor that plays a crucial role in orchestrating the immune response, but its function in tissue inflammatory injury has not been comprehensively studied.

Effects of Xylooligosaccharides on Lipid Metabolism, Inflammation, and Gut Microbiota in C57BL/6J Mice Fed a High-Fat Diet.

Xylooligosaccharide (XOS) is a source of prebiotics with multiple biological activities. The present study aimed to investigate the effects of XOS on mice fed a high-fat diet. Mice were fed either a normal diet or a high-fat diet supplemented without or with XOS (250 and 500 mg/kg), respectively, for 12 weeks.

Upregulation of autophagy in M2 macrophage by vitamin D alleviates crystalline silica-induced pulmonary inflammatory damage.

Crystalline silica (CS) is a universal environmental pollutant, which causes a typical inflammatory lung injury.

Hepatic steatosis and oxidative stress are the main characteristics of NAFLD (nonalcoholic fatty liver disease), which also affect its prognosis. Bixin acts as novel Nrf2 (NF-E2 p45-related factor 2) activator with the cytoprotection against oxidative stress and inflammation; this study mainly focused on the mechanism of Nrf2 activation by bixin and explored its potential feasibilities in long-term high-fat diet- (HFD-) caused hepatic steatosis and inflammatory response and .

Drug-Target Interaction Network Analysis of Gene-Phenotype Connectivity Maintained by Genistein.

Genistein is a type of isoflavone, which has been widely described as an antitumor agent in many cancers. The present study aimed to provide information on the mechanisms of genistein's activity and thus enable a wider range of targeted therapies in hepatitis B virus (HBV)-related liver cancer. We searched the DrugBank database for direct targets of genistein, which were then analyzed through the STRING (Search Tool for the Retrieval of Interacting Genes/Proteins) database to predict their secondary protein targets.
