Antibacterial, cytotoxic and mechanical properties of a orthodontic cement with phosphate nano-sized and phosphorylated chitosan: An in vitro study.

Objectives: Evaluate, in vitro, the effect of incorporating nano-sized sodium trimetaphosphate (TMPnano) and phosphorylated chitosan (Chi-Ph) into resin-modified glass ionomer cement (RMGIC) used for orthodontic bracket cementation, on mechanical, fluoride release, antimicrobial and cytotoxic properties.

Methods: RMGIC was combined with Chi-Ph (0.25%/0.

Influence of titanium and zirconia substrates on the synthesis of inflammatory mediators.

The repair and homeostasis of peri-implant tissues depend on several factors such as the local presence of pathogenic bacteria and their products. Among other events, peri-implant tissue response is also related to the implant material used, which interferes with cells and extracellular matrix interactions, affecting the osseointegration process. In this study, the influence of zirconia (Zr) and titanium (Ti) substrates on the response of preosteoblasts (MC3T3) and murine macrophages (RAW 264.

Skeletal muscle overexpression of sAnk1.5 in transgenic mice does not predispose to type 2 diabetes.

Genome-wide association studies (GWAS) and cis-expression quantitative trait locus (cis-eQTL) analyses indicated an association of the rs508419 single nucleotide polymorphism (SNP) with type 2 diabetes (T2D). rs508419 is localized in the muscle-specific internal promoter (P2) of the ANK1 gene, which drives the expression of the sAnk1.5 isoform.

Dimerization of the C-type lectin-like receptor CD93 promotes its binding to Multimerin-2 in endothelial cells.

Blocking the signaling activated by the plasma membrane receptor CD93 has recently been demonstrated a useful tool in antiangiogenic treatment and oncotherapy. In the proliferating endothelium, CD93 regulates cell adhesion, migration, and vascular maturation, yet it is unclear how CD93 interacts with the extracellular matrix activating signaling pathways involved in the vascular remodeling. Here for the first time we show that in endothelial cells CD93 is structured as a dimer and that this oligomeric form is physiologically instrumental for the binding of CD93 to its ligand Multimerin-2.

CD93 Signaling via Rho Proteins Drives Cytoskeletal Remodeling in Spreading Endothelial Cells.

During angiogenesis, cell adhesion molecules expressed on the endothelial cell surface promote the growth and survival of newly forming vessels. Hence, elucidation of the signaling pathways activated by cell-to-matrix adhesion may assist in the discovery of new targets to be used in antiangiogenic therapy. In proliferating endothelial cells, the single-pass transmembrane glycoprotein CD93 has recently emerged as an important endothelial cell adhesion molecule regulating vascular maturation.
