Influence of platelet rich fibrin (PRF) on proliferation of human preadipocytes and tympanic keratinocytes: A new opportunity in facial lipostructure (Coleman's technique) and tympanoplasty?
The PRF, considered as a healing biomaterial, could be used in tympanic and facial lipostructures surgeries, in order to improve the therapeutic result. Other applications in microsurgery and in plastic surgery may be possible, but specific clinical studies need to validate such protocols.
An up-regulation of maspin expression precedes, rather than occurs at, the critical transition from premalignant prostate lesion of HGPIN to PC. Our data suggest maspin may mark an important transitional phase and play an important role in the premalignancy of the prostate gland.
