Multifunctional CuBiS-BP@PEI Radiosensitizer with Enhanced Reactive Oxygen Species Activity for Multimodal Synergistic Therapy.

Development of radiosensitizers with high-energy deposition efficiency, electron transfer, and oxidative stress amplification will help to improve the efficiency of radiotherapy. To overcome the drawbacks of radiotherapy alone, it is also crucial to design a multifunctional radiosensitizer that simultaneously realizes multimodal treatment and tumor microenvironment modulation. Herein, a multifunctional radiosensitizer based on the CuBiS-BP@PEI nanoheterostructure (NHS) for multimodal cancer treatment is designed.

Gracillin relieves pulmonary fibrosis by suppressing the STAT3 axis.

Ethnopharmacological Relevance: Pulmonary fibrosis (PF) is a persistent and refractory illness accompanied by inflammation and fibrosis. Gracillin, a natural steroidal saponin, is one of the components of Dioscorea quinqueloba which has been used in herbal medicines for treating some inflammatory diseases. Therefore, it may be a potential drug candidate for PF management.

Acetylshikonin exerts anti-tumor effects on non-small cell lung cancer through dual inhibition of STAT3 and EGFR.

Background: Lung cancer is one of the most common types of malignant tumor. It has one of the highest morbidity and mortality rates worldwide, and approximately 85% of cases are non-small cell lung cancer (NSCLC). Clinically, several EGFR inhibitors have been used to treat NSCLC, but resistance can develop.

Hypocrellin A exerts antitumor effects by inhibiting the FGFR1 signaling pathway in non-small cell lung cancer.

Background: Non-small cell lung cancer (NSCLC) accounts for approximately 85% of lung cancer, which is the deadliest form of cancer worldwide. Recent studies have shown that genes in the fibroblast growth factor (FGF) family are highly mutated in lung cancer, and fibroblast growth factor receptor 1 (FGFR1) has been found to be involved in various cancers, including lung cancer, suggesting that FGFR1 is a valid therapeutic target. Hypocrellin A (HA), a molecule with multiple biological activities, has been shown to influence cancer growth, but the specific mechanisms of its antitumor action have not been fully explored.

[Wastewater from the condensation and drying section of ABS was pretreated by microelectrolysis].

Wastewater from the condensation and drying section of acrylonitrile-butadiene-styrene (ABS) resin plant was pretreated by the microelectrolysis, and the effect of the influent pH value on the pollution removal efficiency of the microelectrolysis was mainly studied. In order to study the electrochemical action of the microelectrolysis for the degradation of toxic refractory organic pollutants, two control experiments of activated carbon and iron were set up. The results showed that the TOC removal efficiencies were all fluctuated between 40% and 60% under the condition of different influent pH values.
