Effect of Lead Nanoparticles Inhalation on Bone Calcium Sensing Receptor, Hydroxyapatite Crystal and Receptor Activator of Nuclear Factor-Kappa B in Rats.

This study aimed to investigate whether Pb nanoparticle exposure affects the bone calcium sensing receptor (CaSR), hydroxyapatite crystal, and receptor activator of nuclear factor-kappa B (RANK) in rats exposed to subchronic and chronic inhalation. Thirty two rats were randomly divided into eight groups. One group is a non-exposed group.

Regulation by Phloroglucinol of Nrf2/Maf-Mediated Expression of Antioxidant Enzymes and Inhibition of Osteoclastogenesis via the RANKL/RANK Signaling Pathway: In Silico study.

Introduction: Phloroglucinol is an antioxidant compound with many positive effects on health. The purpose of this study was to determine the role of phloroglucinol in osteoclastogenesis via the RANKL/RANK signaling pathway and the activity of the transcription factor Nrf2.

Material And Methods: Analysis was performed in silico using the primary method of docking by the use of Hex 8.
