Sulfone-Embedded NIR Fluorophore with Large Stokes Shift for Monitoring Viscosity Changes during NAFLD-Induced Ferroptosis.

The accumulation of lipids in hepatocytes in nonalcoholic fatty liver disease (NAFLD) leads to an increase in reactive oxygen species and changes in the intracellular microenvironment, while ferroptosis is the result of the accumulation of iron-dependent lipid peroxidation. Studies have shown that ferroptosis plays an important role in the pathogenesis of NAFLD. Herein, we have developed a viscosity-sensitive fluorescence probe PTSO with near-infrared emission and a large Stokes shift, which were achieved by introducing the sulfone group into the dioxothiochromen-malononitrile fluorophore as an electron-withdrawing group.

Furthermore, the previous studies do not investigate whether living with a father or a mother has differing impacts on the mental health of adolescents, nor does it explore potential differences between biological parents and step-parents in this regard.

Study Aims: This study aims to explore the impact of various living arrangements during the COVID-19 pandemic on the mental health of adolescents, with a particular focus on parental presence and family structure.

Hybrid prodrug nanoassembly for hypoxia-triggered immunogenic chemotherapy and immune modulation.

Tumor hypoxia is a critical driver of cancer progression, metastasis, and therapy resistance, posing significant challenges in effective cancer treatment. Hypoxia-activable prodrugs offer a promising strategy to target tumors in low-oxygen conditions, but their efficacy is often hindered by intrinsic properties and extrinsic cues. In this study, we developed a dual-prodrug nanoassembly system (CPPA) composed of a hypoxia-triggerable camptothecin (CPT)-based dimeric prodrug (CP) and a lipid-conjugated STAT3 antisense oligonucleotide (ASO) prodrug (PA), aiming to enhance tumor-targeted chemotherapy and overcome the immune evasion within the tumor microenvironment.

eradication for primary prevention of gastric cancer: progresses and challenges.

Gastric cancer remains a significant global health challenge, causing a substantial number of cancer-related deaths, particularly in China. While the exact causes of gastric cancer are still being investigated, () infection has been identified as the primary risk factor, which triggers chronic inflammation and a multistage progression of gastric lesions that may lead to carcinogenesis over a long latency time. Since the 1990s, numerous efforts have focused on assessing the effectiveness of eradication in preventing new cases of gastric cancer among both the general population and patients who have undergone early-stage cancer treatment.

Functional characterization and mechanism of the multidrug resistance transport potein YoeA in Bacillus subtilis.

Transport proteins are essential for bacterial resistance to antibiotics and toxins, but their mechanisms remain poorly understood in Bacillus subtilis. In the present study, overexpression of yoeA enhanced resistance to various antibiotics, with its expression induced by these antibiotics, especially penicillin and plipastatin. The ΔyoeA strain exhibited significant growth inhibition at 100 μg/mL of plipastatin, while as high as 10,000 μg/mL of iturin/surfactin are required to achieve comparable inhibition, suggesting a higher sensitivity of ΔyoeA to plipastatin.

Berberine ameliorates dextran sulfate sodium -induced colitis through tuft cells and bitter taste signalling.

Background: Inflammatory bowel disease (IBD), a persistent gastrointestinal disease, is featured with impaired gut immunity. Previous studies have demonstrated that tuft cells can regulate the intestinal type 2 immune response by activating downstream ILC2 and Th2 cells and repair gut barrier upon invasion of parasitic helminths, bacteria, protozoans, and enteritis through different chemo-sensing receptors, such as bitter taste receptors. Berberine is a widely used in the treatment of diarrhea in clinic, however the mechanism underlying this effect is not clear.

The role of reactive oxygen species in severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) infection-induced cell death.

Coronavirus disease 2019 (COVID-19) represents the novel respiratory infectious disorder caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and is characterized by rapid spread throughout the world. Reactive oxygen species (ROS) account for cellular metabolic by-products, and excessive ROS accumulation can induce oxidative stress due to insufficient endogenous antioxidant ability. In the case of oxidative stress, ROS production exceeds the cellular antioxidant capacity, thus leading to cell death.

Rituximab induces ferroptosis and RSL3 overcomes rituximab resistance in diffuse large B-cell lymphoma cells.

Diffuse large B-cell lymphoma (DLBCL) is the most common malignant lymphoma in adults, and the use of rituximab has greatly improved the survival of DLBCL patients.
