[Plant Growth-promoting Bacteria Alleviate the Toxic Effects of Soil Microplastics and Heavy Metal Complex Pollution in ].

The coexistence of microplastics and heavy metals in soil can lead to more intricate environmental effects. While plant growth-promoting bacteria have been widely recognized for enhancing the remediation of heavy metal-contaminated soils, little research has been conducted to investigate whether they can alleviate the stress of microplastic-heavy metal composite contamination on plants. We investigated the effects of isolated and screened plant growth-promoting bacteria on the growth and cadmium （Cd） accumulation of under the composite pollution of Cd and polypropylene （PP） with different particle sizes （6.

[Advantages and application prospects of model organism Drosophila in modern research of traditional Chinese medicine].

Traditional Chinese medicine(TCM) is widely used to prevent and treat various diseases due to its many active ingre-dients, diverse biological activities, low side effects, and drug resistance. The classical model organism Drosophila melanogaster, with its advantages of short life cycle, simple physiological structure, low cultivation cost, and easy operation, has been widely used in the modern research of TCM through gene regulation techniques including transgenic and gene knockout techniques. In this paper, the application of Drosophila in modern research of TCM was outlined from the disease models of inflammatory bowel disease, aging, tumor, neurodegenerative disease, and sleep disorders, with a view to providing new methods and techniques for the research and application of the model organism Drosophila in the field of TCM.

Ononin promotes radiosensitivity in lung cancer by inhibiting HIF-1α/VEGF pathway.

Background: In our previous study, we provided evidence that Astragalus mongholicus Bunge(AM) and its extracts possess a protective capability against radiation-induced damage, potentially mediated through the reduction of reactive oxygen species (ROS) and nitric oxide (NO). However, we were pleasantly surprised to discover during our experimentation that AM not only offers protection against radiation damage but also exhibits a radiation sensitization effect. This effect may be attributed to a specific small molecule present in AM known as ononin.
