Do zinc and copper play a role in coaggregation inhibiting action of Porphyromonas gingivalis?
Our findings suggest that zinc and copper ions markedly enhanced the adhesion and accumulation of salivary and serum proteins on cells of P. gingivalis and inhibited the coaggregation and hemagglutination of P. gingivalis. These cations might be useful for limiting the settlement of P. gingivalis in the gingival sulcus with the goal of preventing periodontal disease.
Sclerostin was significantly lower in OA plasma samples when compared with healthy controls. Plasma and synovial fluid sclerostin levels were inversely associated with the radiographic severity of knee OA. Therefore, sclerostin may be utilized as a biochemical marker for reflecting disease severity in primary knee OA.
