Inflammation in the lungs of mice due to methyl methacrylate exposure.

Aim: This study aimed to predict the potential inflammation in lungs caused by exposure to methyl methacrylate (MMA; study) and assess inflammation in lungs in response to MMA inhalation in mice ( study).

Materials And Methods: and studies were performed using 24 mice divided into a control group (0 ppm MMA) and five treatment groups, which were exposed to 150 ppm MMA for 40, 80, 120, 160, and 200 min, respectively. Lung tissues were harvested and examined with a light microscope at 400×.

Osteogenic Differentiation of Human Amniotic Mesenchymal Stem Cells in Chitosan-Carbonate Apatite Scaffold ( Study).

Background: Studies of bone tissue engineering as a viable alternative to autogenous bone graft show promising results, although its mechanism and effectiveness remain only partially understood.

Purpose: To explain the osteogenic differentiation of scaffold chitosan (Ch)-carbonate apatite (CA) in seeding with human amniotic mesenchymal stem cells (hAMSCs) on the regeneration of calvarial bone defects in rats.

Materials And Methods: Shitosan-Carbonate Apatite (Ch-CA) scaffold was created by means of a freeze-drying method.

The Effect of Combination Spirulina-chitosan on Angiogenesis, Osteoclast, and Osteoblast Cells in Socket Models of Hyperglycemic .

Background: Prolongation of the inflammatory process in hyperglycemic interferes with bone formation, inhibits the healing process, and triggers bone resorption. A combination of spirulina and chitosan in the tooth socket of is expected to promote the bone remodeling process. This study aimed to evaluate the effect of spirulina and chitosan on angiogenesis, osteoclast, and osteoblast cell in tooth socket models of type 1 diabetes.

Effect of lipopolysaccharide derived from surabaya isolates on alveolar bone destruction.

Background: lipopolysaccharide (LPS) has a high virulence factor. It interacts with serum protein through receptors on the epithelial cell surface, thereby increasing both interleukin (IL)-1β, and IL-6 which results in damage to periodontal tissue.

Aim: The aim of the study was to identify and evaluate the effect of LPS derived from local isolates ( on the destruction of alveolar bone by means of several biomarkers, including; the number of osteoblasts and osteoclasts, the expression of IL-6, matrix metallopeptidase 1 (MMP-1), and receptor activator of nuclear factor kappa-Β ligand (RANKL).

In vitro and in vivo evaluation of carbonate apatite-collagen scaffolds with some cytokines for bone tissue engineering.

Background: Collagen is regarded as one of the most useful biomaterials. We tried to combine collagen and carbonate apatite (CA) with some cytokines in order to enhance bone formation ability. In this study, we found that CA-collagen sponge (CA-CS) was a possible candidate of newly graft material for bone formation.
