Elevated serum triglyceride and low-density lipoprotein cholesterol promotes the formation of colorectal polyps.

Background: Hyperlipidaemia may be a potential risk factor for the occurrence of intestinal polyps. This study aimed to evaluate correlation between lipidaemia and the formation of colorectal polyps.

Methods: One hundred and fourteen patients with colorectal polyps and forty-eight healthy controls were included in this study.

Preparation and biological characterization of the mixture of poly(lactic-co-glycolic acid)/chitosan/Ag nanoparticles for periodontal tissue engineering.

Objective: This study aims to produce nanoparticles of chitosan (CS), poly(lactic-co-glycolic acid) (PLGA), and silver and investigate the optimal composite ratio of these three materials for periodontal tissue regeneration.

Methods: PLGA nanoparticles (nPLGA), CS nanoparticles (nCS), and silver nanoparticles (nAg) were prepared. The antibacterial properties of single nanoparticles and their effects on the proliferation and mineralization of periodontal membrane cells were investigated.

Climate change risk perception in global: Correlation with petroleum and liver disease: A meta-analysis.

Background: Liver diseases have been bound to environmental factors, inclusive of air pollution. The exposure of workers to petrochemicals counts as a possible cause of Liver diseases, whereas results are inconsistent with the previous studies. In this study, a meta-analysis is conducted to assess the pooled risk.

Shear Bond Strength of Different CAD/CAM Ceramics: Acid vs Er:YAG Laser Etching.

Objective: To evaluate whether Er:YAG laser etching could be an alternative surface treatment to hydrofluoric (HF) acid etching.

Background: Surface treatment is important to bonding properties and utility times of computer aided design/computer aided manufacture (CAD/CAM) dental ceramics. The traditional method of HF acid etching is harmful to humans if not handled properly.

The use of chitosan/PLA nano-fibers by emulsion eletrospinning for periodontal tissue engineering.

Objective: In this study, nanofibrous scaffolds base on pure polylactic acid (PLA) and chitosan/PLA blends were fabricated by emulsion eletrospinning. By modulating their mechanical and biological properties, cell-compatible and biodegradable scaffolds were developed for periodontal bone regeneration.

Methods: Pure PLA and different weight ratios of chitosan nano-particle/PLA nano-fibers were fabricated by emulsion eletrospinning.

Drug-Loadable Calcium Alginate Hydrogel System for Use in Oral Bone Tissue Repair.

This study developed a drug-loadable hydrogel system with high plasticity and favorable biological properties to enhance oral bone tissue regeneration. Hydrogels of different calcium alginate concentrations were prepared. Their swelling ratio, degradation time, and bovine serum albumin (BSA) release rate were measured.
