Experimental allergic airway inflammation impacts gut homeostasis in mice.

Background: /Aims: Epidemiological data show that there is an important relationship between respiratory and intestinal diseases. To improve our understanding on the interconnectedness between the lung and intestinal mucosa and the overlap between respiratory and intestinal diseases, our aim was to investigate the influence of ovalbumin (OVA)-induced allergic airway inflammation on gut homeostasis.

Methods: A/J mice were sensitized and challenged with OVA.

Probiotics During the Therapeutic Management of Periodontitis.

Scaling and root planing is the gold standard for the treatment of periodontitis, but administration of systemic antibiotics may be needed especially for sites with deep probing depths, or in the presence of comorbidities. However, treated sites are subject to recolonization with a microbiota similar to that present before therapy, and supportive periodontal therapy is employed after the treatment of active disease. The use of beneficial organisms, known as probiotics, seems an attractive proposal to promote a healthy associated subgingival microbiome and to control inflammation for the management of periodontitis.

Probiotics improve re-epithelialization of scratches infected by Porphyromonas gingivalis through up-regulating CXCL8-CXCR1/CXCR2 axis.

Porphyromonas gingivalis inhibits the release of CXCL8 by gingival epithelial cells and reduces their proliferation. We previously reported that Bifidocaterium sp. and Lactobacillus sp.

Probiotics alter biofilm formation and the transcription of virulence-associated genes.

Background And Objective: The potential of probiotics on the prevention and control of periodontitis and other chronic inflammatory conditions has been suggested. and species influence interaction with gingival epithelial cells (GECs) but may not act in a unique way. In order to select the most appropriate probiotic against , we aimed to evaluate the effect of several strains on biofilm formation and transcription virulence-associated factors (PgVAFs).

The role of probiotic bacteria in managing periodontal disease: a systematic review.

Introduction: The frequent recolonization of treated sites by periodontopathogens and the emergence of antibiotic resistance have led to a call for new therapeutic approaches for managing periodontal diseases. As probiotics are considered a new tool for combating infectious diseases, we systematically reviewed the evidences for their effectiveness in the management of periodontitis.

Areas Covered: An electronic search was performed in the MEDLINE, SCOPUS and Cochrane Library databases up to March 2016 using the terms 'periodontitis', 'chronic periodontitis', 'probiotic(s)', 'prebiotic(s)', 'symbiotic(s)', 'Bifidobacterium and 'Lactobacillus'.

Study of the surface hardness and modulus of elasticity of conventional and microwave-cured acrylic resins.

The aim of this study was to evaluate the following acrylic resins: Clássico, QC-20 and Lucitone, recommended specifically for thermal polymerization, and Acron MC and VIPI-WAVE, made for polymerization by microwave energy. The resins were evaluated regarding their surface nanohardness and modulus of elasticity, while varying the polymerization time recommended by the manufacturer. They were also compared as to the presence of water absorbed by the samples.
