Ethnopharmacological Relevance: Cisplatin (CP), a widely used antineoplastic agent, is a leading cause of drug-induced liver injury (DILI) due to its hepatotoxic effects. Licorice (GC), an established remedy in traditional Chinese medicine (TCM), has shown promise in addressing liver diseases and DILI. Nonetheless, the specific active components and underlying mechanisms of GC in mitigating CP-induced liver injury remain inadequately investigated.

Due to the variety and activity of secondary metabolites of endophytic fungi (SMEF) from medicinal plants, and the operation cumbersome of existing methods for evaluating the activity, there is urgent to establish a simple, efficient and sensitive evaluation and screening technology. In this study, the prepared chitosan functionalized activated carbon (AC@CS) composite as the electrode substrate material was used to modify glassy carbon electrode (GCE), and the gold nanoparticles (AuNPs) was deposited on AC@CS/GCE by cyclic voltammetry (CV). A ds-DNA/AuNPs/AC@CS/GCE electrochemical biosensor for evaluating the antioxidant activity of SMEF from Hypericum perforatum L.

Sleep debt (SD) is one of the important triggers for causing not only physiological and mental illness but also dangerous work. Therefore, achieving an early and objective assessment of SD is of great significance in the precaution against SD-related diseases and unsafe work. Here, an ultrasensitive electrochemical immunosensor was constructed for analysis of SD biomarker amyloid-β (Aβ).

Article Synopsis
  • The study examined how various traditional Chinese medicine compositions and extraction methods impact mice’s ability to tolerate low oxygen conditions.
  • Male BALB/c mice were divided into 6 groups, with different treatments including compounds like danshen and Rhodiola Rosea, and were tested after 10 days of administration.
  • Results showed that certain treatments, particularly those with compound danshen and Astragalus, significantly improved survival times in hypoxia tests and boosted antioxidant enzyme activity compared to the control group.

Background: Patrinia scabra Bunge is a well-known herbal medicine for its favorable treatment on inflammatory diseases owing to its effective ingredients, in which iridoid glycoside plays an extremely significant role. This article aimed to improve the content of total iridoid glycosides in crude extract through a series optimization of extraction procedure. Moreover, considering that both pain and inflammation are two correlated responses triggered in response to injury, irritants or pathogen, the article investigated the anti-inflammatory and analgesic activities of P.
