Dental implant surfaces treated with phosphoric acid can modulate cytokine production by blood MN cells.

The study characterizes dental implant surfaces treated with phosphoric acid to assess the effects of acid treatment on blood cells and correlate them with cytokine levels. The implant surfaces examined were divided into untreated metal surface (US; n = 50), metal surface treated with phosphoric acid (ATS; n = 50) and cement surface (CS; n = 50) groups. The samples were characterized by scanning electron microscopy (SEM) and rheometry.

Phenotypic characterization of regulatory T cells populations in maternal blood, cord blood and placenta from diabetic mothers.

Changes in regulatory T cells (Treg) in peripheral blood are associated with a number of pathologies, including diabetes. However, the immunological responses of pregnant diabetic women remain scarcely known, and the effects of Treg cells in these patients have yet to be investigated. The present study characterized the expression of regulatory T cells in the maternal blood, cord blood and placenta of diabetic pregnant women.
