Optimizing Desmostachya bipinnata-derived platinum nanoparticles for enhanced antibacterial and biofilm reduction.

This study presents the green synthesis and comprehensive characterization of platinum nanoparticles (PtNPs) using Desmostachya bipinnata (Db) extract, incorporated into two innovative mouthwash formulations (MW1 and MW2). UV-Vis spectroscopy confirmed the successful synthesis of PtNPs, with distinct absorption peaks between 250 and 600 nm. Fourier-transform infrared (FTIR) spectroscopy identified hydroxyl and carbonyl functional groups, critical for the bioreduction and stabilization of PtNPs.

Potential of salivary biomarkers for diagnosing and prognosing rheumatoid arthritis: A systematic review and meta-analysis: Salivary biomarkers in Rheumatoid Arthritis patients - A systematic review with Meta-analysis.

Background: Rheumatoid arthritis (RA) is a chronic debilitating autoimmune disorder. Blood biomarkers, like rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPAs), lack the sensitivity and specificity for early diagnosis, delaying treatment. This review while highlighting the need for new diagnostic tools, emphasizes the promising avenue of saliva for developing RA biomarkers.
