Platelet Rich Plasma and Hyaluronic Acid Blend for the Treatment of Osteoarthritis: Rheological and Biological Evaluation - Fig 1 Fabrizio Russo Matteo D’Este Gianluca Vadalà Caterina Cattani Rocco Papalia Mauro Alini Vincenzo Denaro 10.1371/journal.pone.0157048.g001 https://plos.figshare.com/articles/figure/Platelet_Rich_Plasma_and_Hyaluronic_Acid_Blend_for_the_Treatment_of_Osteoarthritis_Rheological_and_Biological_Evaluation_-_Fig_1/3449243 <p><b>(A)</b> Viscosity curves of the pure viscosupplements. The graph represents the viscosity as a function of the shear rate. For all specimens the typical shear-thinning behavior of HA is observed. SN displays viscosity one order of magnitude lower than the other specimens. <b>(B)</b> Mechanical spectra of the pure viscosupplements. The graph represents the shear storage modulus G' (triangles) and the shear loss modulus G" (circle) as a function of the angular frequency.</p> 2016-06-16 05:57:01 Platelet Rich Plasma Bovine Serum Albumin PRP regenerative properties HX GAG future OA therapy PBS HA concentration Biological Evaluation Introduction Osteoarthritis Results PRP addition BSA synovial fluid SN osteoarthritic chondrocytes SF HL conjugates HA viscosupplementation extracellular matrix production
