Comparison of stress distribution in fully porous and dense-core porous scaffolds in dental implantation.

The aim of this study is to compare the stress distribution in porous scaffolds with different structures with similar geometric parameters to study a new approach in dental implantation. Three-dimensional finite element models of the fully porous and dense-core porous scaffolds with defined porosity parameters including space diameter and thickness with two porosity patterns were embedded in the jaw bone model with cortical and cancellous bone. The cylindrical shape was considered as the main shape of the scaffolds.

Serum Pro-oxidant-antioxidant Balance in Subjects with Type 2 Diabetes Mellitus.

Aim And Objective: Diabetes mellitus is associated with inflammation and increased oxidative stress. In the current study, we aimed to investigate the relationship between type 2 diabetes mellitus (T2DM) and serum pro-oxidant-antioxidant balance (PAB) in a large populationbased study.

Methods: In this cross-sectional study, 7888 individuals were recruited as part of the Mashhad Stroke and Heart Atherosclerotic Disorders (MASHAD) cohort study.

Kinetic and thermodynamic study of beta-Boswellic acid interaction with Tau protein investigated by surface plasmon resonance and molecular modeling methods.

Beta-Boswellic acid (BBA) is a pentacyclic terpene which has been obtained from frankincense and its beneficial effects on neurodegenerative disorders such as Alzheimer's disease (AD) have been addressed. In the present study, thermodynamic and kinetic aspects of BBA interaction with Tau protein as one of the important proteins involved in AD in the absence and presence of glucose has been investigated using surface plasmon resonance (SPR) method. Tau protein was immobilized onto the carboxy methyl dextran chip and its binding interactions with BBA were studied at physiological pH at various temperatures.
