The present study explored the potential role of osteoprotegerin (OPG)/receptor activator of nuclear factor-κB (RANK)/receptor activator of nuclear factor-κB ligand (RANKL) in promoting vascular calcification by periodontitis. Thirty-six male Wistar rats were randomly assigned to four groups to establish animal models as follows: the sham group (group C), vascular calcification group (group VDN), periodontitis group (group CP), and test group (group CP+VDN). After eight weeks, all the rats were sacrificed.

Objective And Background: To study the relationship between periodontitis and vascular calcification by establishing rat model of chronic periodontitis and vascular calcification.

Methods: Forty male Wistar rats were divided into four groups randomly: control group, periodontitis group, vascular calcification group, and compound periodontitis and calcification group. Each group rats accepted the corresponding manages to establish the animal model.

Purpose: To study the expression and possible role of OPG/RANK/RANKLin the rat dental pulp of periodontitis combined with vascular calcification.

Methods: Thirty-six male Wister rats were randomly divided into 4 groups: control group(group C), periodontitis group(group CP), vascular calcification group(group VDN) and compound group(group CP+VDN). Each group underwent corresponding management to establish animal model.

Background: Porphyromonas gingivalis (Pg) is a major etiologic agent of periodontitis, whose virulence has been attributed to different factors, including lipopolysaccharide (LPS). Vascular ectopic calcification as a well-known major risk factor for adverse cardiovascular diseases is a highly prevalent vascular pathophenotype, and vascular smooth muscle cells (VSMCs) play an important role in mediating vascular calcification. It was hypothesized that Pg-LPS may stimulate vascular calcification through a direct effect on VSMC function.

A novel ionic liquid-metal complex (ILMC) electrolyte was developed for dye-sensitized solar cells (DSCs). A high efficiency of nearly 7% was achieved, which was 69.2% higher compared with an ionic liquid (IL) electrolyte without a metal center.

We report important progress made in the synthesis of oriented functional layers of nanochannel materials by using coordination chemistry as a tool. Zeolite L (ZL) crystals have been arranged into oriented layers through the coordinative interactions between a functional organic linker (L) and metal cations used for connecting the different parts. As organic linker we used a terpyridyl ligand bearing a urea group and a reactive siloxane part.
