BACKGROUND AND OBJECTIVES The aim of this study was to compare culture-expanded, bone marrow-derived mesenchymal stem cells (MSCs) and platelet-rich plasma (PRP) loaded to biphasic calcium phosphate (BCP) bone ceramic in the repair of rat calvarial bone. MATERIALS AND METHODS Critical-size (7 mm dia.) calvarial defects were prepared in the frontal-parietal bones of 90 adult female Sprague-Daw...
OBJECTIVE To investigate the therapeutic potential of intra-articular hyaluronan-derivative HYADD® 4-G and/or platelet-rich plasma (PRP) in a mouse model of non-invasive joint injury. METHODS Non-invasive axial tibial loading was used to induce joint injury in 10-week-old C57BL/6J mice (n = 86). Mice underwent a single loading of either 6 Newton (N) or 9N axial tibial compression. HYADD® 4-G ...
Radiation is an important therapy for cancer with many benefits; however, its side effects, such as impaired wound healing, are a major problem. While many attempts have been made to overcome this particular disadvantage, there are few effective treatments for impaired wound healing in an X-ray-irradiated field. One reason for this deficiency is the lack of experimental models, especially anima...
Objectives Autologous bone transplantation known as the "gold standard" to reconstruction of osseous defects has known disadvantages. This study was designed to explore the effects of hydroxy-apatite/tricalcium-phosphate (HA/TCP) and platelet-rich plasma (PRP) on the osteogenesis ability of human adipose-derived mesenchymal stem cells (hAdMSCs) in vitro and in vivo. Materials and Methods hAdM...
Crude brain homogenates of terminally diseased hamsters infected with the 263 K strain of scrapie (PrP Sc) were heated and/or pressurized at 800 MPa at 60 degrees C for different times (a few seconds or 5, 30, 120 min) in phosphate-buffered saline (PBS) of different pH and concentration. Prion proteins were analyzed on immunoblots for their proteinase K (PK) resistance, and in hamster bioassays...
Purpose: The effects of 2 graft materials, -tricalcium phosphate (Cerasorb) alone and a combination of Cerasorb and platelet-rich plasma (PRP), on the bone regeneration process were evaluated in the canine mandible. Materials and Methods: The mandibular premolars of 12 beagle dogs were surgically removed. The extraction sockets were filled with Cerasorb on the control side and a mixture of Cera...
BACKGROUND/AIM Giant cell tumors are mostly benign but locally aggressive tumors. The excision of bone tumors can result in large defects, therefore bone reconstruction is still one the most demanding procedures in orthopedic surgery. Our study addresses the opportunity for improving surgical outcome by employing β-tricalcium phosphate (β-TCP) with platelet-rich plasma (PRP) at the surgical sit...
A sensitive, simple, and reliable high-performance liquid chromatographic method with electrochemical detection is developed for the measurement of four natural products, the serotonin-related indols from human platelet-rich plasma (PRP) using N-methylserotonin as internal standard. Separation of serotonin (5HT), 5-hydroxytryptophan (5HTP), 5-hydroxytryptophol (5HTOL), and 5-hydroxyindole-aceti...
INTRODUCTION Osteoarthritis (OA) is the most common musculoskeletal disease. Current treatments for OA are mainly symptomatic and inadequate since none results in restoration of fully functional cartilage. Hyaluronic Acid (HA) intra-articular injections are widely accepted for the treatment of pain associated to OA. The goal of HA viscosupplementation is to reduce pain and improve viscoelastici...
The introduction of Haemophilus influen-zae serotype b (Hib) conjugate vaccine has been a major step in the prevention of meningitis, epiglottitis, and other manifestations of invasive Hib disease. Because these diseases occur mainly in children, vaccination during infancy prevents the vast majority of cases within a few years. The optimal schedule for Hib vaccination is still a matter of debat...
