The present study was designed to test the hypothesis that the acetonic and methanolic extracts of H. inuloides prevent carbon tetrachloride-(CCl(4)) induced oxidative stress in vital tissues. Pretreatment with both H. inuloides extracts or quercetin attenuated the increase in serum activity of alkaline phosphatase (ALP), total bilirubin (BB), creatinine (CRE), and creatine kinase (CK), and imp...

In the present study, silver nanoparticles (AgNPs) were synthesized in situ on orthodontic elastomeric modules (OEM) using silver nitrate salts as metal-ion precursors and extract of the plant Hetheroteca inuloides (H. inuloides) as bioreductant via a simple and eco-friendly method. The synthesized AgNPs were characterized by UV-visible spectroscopy; scanning electron microscopy-energy-dispersi...

-Sesquiterpenoids, 7-hydroxy-3,4-dihydrocadalin and 7-hydroxycadalin, and flavonoids, quercetin, kaempferol and their glycosides, isolated from Heterotheca inuloides (Asteraceae), a Mexican medicinal plant known as "arnica", were evaluated as antioxidants. These compounds showed potent scavenging activity on diphenyl-p-picrylhydrazyl (DPPH) radical. Microsomal lipid peroxidation induced by Fe(I...

Osteoarthritis is characterised by progressive loss of articular cartilage through the increase of catabolic metalloproteinases, and chondrocyte cytoskeleton disruption has also been reported. In this regard, we studied the effect of Heterotheca inuloides essential oil (HIEO) on the distribution and immunolocalisation of actin, vimentin and tubulin of chondrocytes from cultured rat articular ca...
