objective(s): platelet-rich plasma (prp) has recently emerged as a promising strategy in regenerative medicine due to its multiple endogenous growth factors. little is known about the role of prp as a promoter in chondrogenesis of human adipose derived stem cells (hadscs). the aim of this study was to determine whether prp may be considered as a natural and easy achievable source of growth fact...

the purpose of the present randomized clinical trial study was to compare the effectiveness of bovine porous bone mineral (bpbm) with and without plasma rich in growth factors (prgf) in the treatment of mandibular class ii furcation defects.in seven patients, nine pairs of symmetric buccal or lingual mandibular class ii furcation defects were treated. in each patient, one defect received bpbm (...

the synthesis of 3-amino-1-nitroguanidine (3-anq) and 5-hydrazino tetrazole (5-ht) derivatives as new energetic materials are described. reaction of 3-anq with triethyl orthoformate leads to the formation of 3-nitramino triazole while no reaction was observed whit 5-ht. addition of nan3 to a mixture of 3-anq and triethyl orthoformate, afforded 1-nitroguanidyl tetrazole in excellent yield. on th...

conclusions both l-prp and l-prf could be used to effectively promote the healing of articular cartilage defects of the knee. results mean macroscopic scores of the treated defects were higher than the controls at all sampling times with significant differences (p < 0.05) observed between l-prf treated and control defects (10.13 vs. 8.37) and l-prp treated and control defects (10 vs. 8.5) at 4 ...

objective- this study aimed to evaluate the feasibility of using platelet rich fibrin membrane as a novel on-lay patching biomaterial in canine esophagotomy and its effects on esophageal wound healing. design- experimental study. animals- eight adult mixed breed dogs of both sexes equally allocated to control and treatment groups. procedures- longitudinal incisions measuring 3 cm were made in t...

in this work, thermal degradation behavior of a fuel-rich energetic mixture containing epoxy binder was studied by thrmogravimetric analysis and differential scanning calorimetry under dynamic nitrogen atmosphere at different heating rates. variation of the thermal degradation activation energy of the mixture was evaluated by differential and integral isoconversional methods via akts software p...

blood transfusion centers are under considerable pressure to produce platelet concentrates with high quality and safety due to the short shelf life of 3-5 days as well as possible bacterial and viral contaminations. for a variety of reasons, many europeans have changed their methods of component production from whole blood using the north american standard platelet-rich plasma method to the buf...

objective: to assess the effects of platelet rich plasma (prp) with chitosan biodegradable film on full thickness wound healing in rat. methods: this was an experimental study being performed in 2015 during a 4-month period. twenty-four male white wistar rats were divided into four groups of 12 rats each, randomly: control group (sham) with creation of wounds and no treatment, prp group with cr...
