We aimed to determine the chemical profile and unveil Anadenanthera colubrina (Vell.) Brenan standardized extract effects on inflammatory cytokines expression and key proteins from immunoregulating signaling pathways on LPS-induced THP-1 monocyte. Using the RT-PCR and Luminex Assays, we planned to show the gene expression and the levels of IL-8, IL-1β, and IL-10 inflammatory cytokines.

Methods, we synthesized a glass nanoparticle by Sol-Gel Stöber method, used to be incorporated in a dental material for endodontic uses.
Materials And Methods: We assess the mineralizing properties and biocompatibility.
() is abundant within the microbial dysbiotic community of some patients with periodontitis. outer membrane protein 29 (OMP29), a member of the OMPA family, mediates the invasion of to gingival epithelial cells (GECs). This study evaluated the effect of OMP29 and its paralogue OMP29 on the response of GECs to .

Plant extracts with strong antiviral activity working in nanomolar or picomolar range can be used to enhance the activity of synthetic compounds and work as anti-HIV agents.

For this, the Aa, was applied to cross the monolayer of epithelial keratinocytes (OBA-9) to reach the fibroblasts layer (HGF-1) in the basal chamber. The Monolaurin treatments (25 or 50 μM) were added immediately after the inoculation of the dual-chamber with Aa.

Curcumin is used as a spice, food preservative, flavoring, and coloring agent that has been shown to have many pharmacological activities. Thus, this study evaluated the modulatory effects of curcumin on major virulence factors associated with the pathogenicity of .

Material And Methods: Genomic DNA and total RNA were purified from gingival tissue using the TRIZOL reagent protocol. Genomic DNA was then digested by methylation-sensitive restriction enzymes, amplified by polymerase chain reaction (PCR), electrophoresed on a 10% polyacrylamide gel and stained using SYBR Gold.
Latex extracted from Hevea brasiliensis was used as an occlusive membrane for guided bone regeneration. Twenty-four rabbits were divided in two groups: treated and control group. Critical size bone defects (2 cm × 1 cm) were surgically made in the rabbit calvarium.

Design: Ethanol was administered to drinking water (treated group) starting at concentrations of 1% and increasing weekly to 5, 10, 15, 20 and 25% (v/v). During week 7, these rats were mated and continued to receive the 25% alcoholic solution, up to delivery.
