Activation of the NF-κB signaling pathway by Reynoutria japonica Houtt ameliorates complete Freund's adjuvant-induced arthritis in rats.

Background: Rheumatoid arthritis (RA) manifests through persistent synovitis and systemic inflammation, which ultimately result in the degradation of cartilage and bone. The current study was to scrutinize the anti-arthritic effect of Reynoutria japonica Houtt ameliorating complete Freund's adjuvant (CFA)-induced RA in rats and explore the underlying mechanism.

Material And Methods: CFA was used for the induction of RA in the rats (rats were received the oral administration of Reynoutria japonica Houtt) and estimation of body weight and organ weight.

Molecular mechanism of the effect of BixiezelanYin on knee osteoarthritis based on network pharmacology and molecular docking.

The BixizelanYin (BXZLY) is a traditional herbal formula for treating damp-heat type knee osteoarthritis (KOA). This study aimed to investigate the potential therapeutic effects of BXZLY on KOA by using network pharmacology and molecular docking. Active ingredients and their corresponding targets of BXZLY were screened through the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform.

Maximizing Interlaminar Fracture Toughness in Bidirectional GFRP through Controlled CNT Heterogeneous Toughening.

"Interleaving" is widely used for interlaminar toughening of fiber-reinforced composites, and the structure of interleaving is one of the important factors affecting the toughening efficiency of laminates. Several experiments have demonstrated that compared to continuous and dense structures, toughening layers with structural heterogeneity can trigger multiple toughening mechanisms and have better toughening effects. On this basis, this work further investigates the application of heterogeneous toughening phases in interlaminar toughening of bidirectional GFRP.

Anti-inflammatory Effect of Pomelo Peel and Its Bioactive Coumarins.

(L.) Osbeck is a popular fruit cultivated around the world, and its peels are sometimes used for the treatment of cough, abdominal pain, and indigestion in China. However, the peel is discarded after fruit consumption in most cases, and its chemical constituents and biological activities have not been validated before.

Novel nor-monoterpenoid indole alkaloids inhibiting glioma stem cells from fruits of Alstonia scholaris.

Background: Glioblastoma multiforme (GBM) is a highly aggressive and frequently recurrent malignant brain tumor, and to date, the clinically effective drugs against GBM remain scarce. Natural products play an important role in drug discovery, and might be the resource of antitumor agents for GSCs. Alstonia scholaris (L.

Antitumor Triterpenoid Saponin from the Fruits of Avicennia marina.

The fruits of Avicennia marina are widely used for both medicine and food in Guangxi of China. As a part of our continuous effort to search for bioactive molecules from the plant, the fruits of A. marina were investigated, which has led to one new triterpenoid saponin (1) and 29 known compounds been isolated and their structures were established by using spectroscopic methods and comparing with literature data.
