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.

Effects of barium chloride adsorbed to polyethylene glycol (PEG) microspheres on co-culture of human blood mononuclear cell and breast cancer cell lines (MCF-7).

This study investigated the effects of BaCl adsorbed to polyethylene glycol (PEG) microspheres on human blood mononuclear cells (MN) co-cultured with breast cancer cell lines (MCF-7). The MCF-7 cells were obtained from the American Type Culture Collection and the blood mononuclear (MN) cells from volunteer donors. MN cells, MCF-7 cells and their co-culture (MN and MCF-7 cells) were pre-incubated for 24 h with or without 25 and 1000 pg L BaCl (Ba and Ba), PEG microspheres or 25 and 1000 pg L BaCl adsorbed to PEG microspheres (PEG-Ba and PEG-Ba).

Herbal Mixture Adsorbed to Polyethylene Glycol Microspheres Induces Apoptotic Effects on Breast Cancer Cells.

Background: The combination of medicinal plants and polymeric matrices raised the possibility of obtaining new drugs to treat a number of diseases, including cancer. Breast cancer is one of the most frequent diseases among women, but the effective treatments is still a challenge.

Methods: Thus, this study investigated the effect of herbal mixture adsorbed to PEG microspheres on MCF-7 human breast cancer cells and these cells in co-culture of blood MN cells.
