Advanced Functional Materials, EarlyView.Schematic illustration of LNP‐MPG nuclei‐targeting delivery of HMW‐FGF2 promoting histone acetylation to regulate the fate of DPSCs and treat spinal cord injury. LNPs components include pHMW‐FGF2 plasmid, DSPC, Dlin‐MC3‐DMA, cholesterol, and PEG2000, and are modified with MPG to form HMW‐FGF2@LNP‐MPG (HLM). HLM nuclei‐targets DPSCs to deliver HMW‐FGF2,

The stress distribution of implants made of Polyaryletherketones: A 3D Finite Element Analysis
Acta Odontologica TurcicaOBJECTIVE: To explore the stress distribution on the bone-implant structures caused by the Polyetheretherketone (PEEK), Polyetherketoneketone (PEKK), and titanium fixture/abutments by using the three-dimensional (3D) finite element analysis (FEA ...

EXPERIMENTAL STRESS ANALYSIS AND FEA OF DENTAL IMPLANTS
International Journal of Research in Engineering and Technology, 2016 Dental implants are used as prosthetic treatment alternatives made of Titanium for treating partial edentulism in patients. The oessointegration of bone and implant at the interface is of utmost importance as the success or failure of a dental implant depends on the manner in which stresses are transferred to the surrounding bone.
