Bioactivity and cellular structure of Candida albicans and Candida glabrata biofilms grown in the presence of fluconazole.

Objective: The aim of this study was to evaluate whether fluconazole (FLZ) could affect the bioactivity and cellular structure of Candida albicans or Candida glabrata biofilms grown in the presence of FLZ.

Materials And Methods: Tokens were fabricated using poly(methylmethacrylate) resin (PMMA) in a hot water bath. Salivary pellicles were formed on the PMMA surface, and biofilms of a reference strain and two clinical isolates of C.

Immunolocalization and activity of the MMP-9 and MMP-2 in odontogenic region of the rat incisor tooth after post shortening procedure.

MMP-9 and MMP-2 are metalloproteinases which degrade the denatured collagen fibers. However, there is no report about roles of these MMPs in the odontogenic region of the adult rat incisor tooth under different eruption conditions. Male Wistar rats were divided in a normofunctional group (NF) in which their lower teeth remained in a normal eruption.

Increase of MT1-MMP, TIMP-2 and Ki-67 proteins in the odontogenic region of the rat incisor post-shortening procedure.

MT1-MMP and TIMP-2 are well known for their roles in remodelling of extracellular matrix components. However, reports are emerging on the involvement of these molecules in cell kinetics. In the rat incisor tooth, a shortening treatment increases the eruption and cell proliferation rates.

Influence of different decalcifying agents on EGF and EGFR immunostaining.

This study was designed to verify the influence of three demineralizing agents on EGF and EGFR immunostaining as well as on tissue morphology. We chose submandibular glands that are a source of EGF and its receptor and which could be analyzed using a control in which the decalcification step was not carried out. After sacrifice of adult male Wistar rats by perfusion fixation, the submandibular glands and mandibles were excised and placed together in each of the following solutions: (a) 5% nitric acid in 4% formaldehyde; (b) 4.
