Non‐locked and locked small fragment straight plates have a similar behavior in buttressing the posteromedial shear tibial plateau fragment: a biomechanical analysis of three different fixations

Journal of Experimental Orthopaedics, Volume 7, Issue 1, 2020., 2020
Abstract Purpose The aim of this study is to compare the biomechanical behavior of three different fixation constructions currently used for buttressing the posteromedial shearing tibial plateau fragment. Our hypothesis is that non‐locked implants provide sufficient comparable stability in posteromedial tibial plateau fractures as locked implants ...

Internal Friction and Microstructure of Ti and Ti-Mo Alloys Containing Oxygen

Archives of Metallurgy and Materials, 2016
Ti-Mo alloys are promising materials for use as biomaterials, because these alloys have excellent corrosion resistance and a good combination of mechanical properties such as fatigue, low elastic modulus, hardness, and wear resistance.

Effect of the substitutional elements on the microstructure of the Ti-15Mo-Zr and Ti-15Zr-Mo systems alloys

Journal of Materials Research and Technology, 2015
Titanium alloys have excellent biocompatibility, and combined with their low elastic modulus, become more efficient when applied in orthopedic prostheses.

Interaction of cultured human endothelial cells with polymeric surfaces of different wettabilities [PDF]

, 1985
The in vitro interaction of human endothelial cells (HEC) and polymers with different wettabilities in culture medium containing serum was investigated. Optimal adhesion of HEC generally occurred onto moderately wettable polymers.

Pattern of sympathetic vasomotor activity in a model of hypertension induced by nitric oxide synthase blockade

Physiological Reports, Volume 7, Issue 14, July 2019., 2019
Hypertension induced by NO synthase blockade is characterized by increased sympathetic nerve activity to renal (rSNA) and splanchnic nerve (sSNA). The rats that had the greatest reduction in NO levels in plasma by L‐NAME were those that developed higher blood pressure levels.

Evaluation of Hemagglutination Activity of Chitosan Nanoparticles Using Human Erythrocytes

BioMed Research International, Volume 2015, Issue 1, 2015., 2015
Chitosan is a polysaccharide composed of randomly distributed chains of β‐(1‐4) D‐glucosamine and N‐acetyl‐D‐glucosamine. This compound is obtained by partial or total deacetylation of chitin in acidic solution. The chitosan‐based hemostatic agents have been gaining much attention in the management of bleeding.

Cell Adhesion to Plasma‐Coated PVC

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
To produce environments suitable for cell culture, thin polymer films were deposited onto commercial PVC plates from radiofrequency acetylene‐argon plasmas. The proportion of argon in the plasmas, PAr, was varied from 5.3 to 65.8%. The adhesion and growth of Vero cells on the coated surfaces were examined for different incubation times.
