This study reports the beneficial effect of aqueous extract of dried flower buds of Syzygium aromaticum (clove) in acute and chronic inflammation. Inflammation was induced in rats by injecting carrageenan in hind paw or implanting cotton pellet in the axilla. Administration of the extract (1 g/kg body weight) inhibited the formation of oedema induced by carrageenan and decreased granuloma in cotton pellet granuloma model. The extract, when compared with the disease control, is reported to decrease the elevated levels of succinate dehydrogenase (p<0.001), xanthine oxidase (p<0.05) and lipid peroxidation, and increase the activity of catalase (p<0.001) and glutathione peroxidase (p<0.01) in the two animal models. Potential role of xanthine oxidase in inflammation and the ability of the extract to alleviate oxidative stress and inflammation is discussed. The study advocates the use of aqueous extract, rather than the isolated bioactive principle for various reasons.

Dental caries is a highly prevalent chronic condition globally. In recent years, scientists have turned to natural compounds such as plant extracts as an alternative to address concerns related to biofilm-mediated disease transmission, increasing bacterial resistance, and the adverse impacts of antibiotics. Consequently, this study investigated the antimicrobial properties of ethanolic, hydroethanolic, and aqueous extracts of L.

The limited availability of uranium (U) resources poses significant challenges to the advancement of nuclear energy. Recycling uranium from spent fuel is critical, but the coexistence of lanthanides (Ln) complicates the extraction process significantly. Here, we present an N/O ligand, ()-'-(pyridin-2-ylmethylene) picolinohydrazide (), designed for the selective recovery of U(VI) over Ln(III/IV) in acidic environments.
