Purpose Herein we evaluated the effects of platelet concentrate (PC) and platelet-poor plasma (PPP) on bone repair using noncritical defects in calvaria rabbits compared them to presence TGF-β1 osteocalcin reparative sites. Methods Five 8.7 mm diameter were created 15 animals. Each defect was treated differently, autograft (ABG), ABG associated with PC (ABG + PC), PPP PPP), isolated PPP, blood ...

Structural and bonding patterns arising from the incorporation of fluorine atoms in a graphene-like network relevant to the deposition of carbon fluoride (CFx) films were addressed by first-principles calculations. We find that large N-member (N=8 – 12) rings, defects by sheet branching, and defects associated with bond rotation pertain to CFx. The cohesive energy gains associated with these pa...

PURPOSE Artificial grafts have been investigated for use in the repair of oral mucosal defects. The aim of this retrospective study was to present the outcomes of the use of acellular dermal matrix (ADM) grafts to repair oral mucosal defects. MATERIALS AND METHODS Data from 36 patients with oral mucosal defects reconstructed with ADM grafts from 2003 through 2009 were reviewed. All patients w...

We study the initial stages of homogeneous melting a hexagonal ice crystal at coexistence and moderate superheating. Our trajectory-based computer simulation approach provides comprehensive picture events that lead to melting; from accumulation 5+7 defects, via formation L-D interstitial-vacancy pairs, liquid nucleus. Of different types defects we observe be involved in melting, particular kind...

BACKGROUND Visual dysfunction is common in Parkinson's disease (PD). It remains, however, unknown whether it is related to structural alterations of the retina. The aim of this study is to compare visual field (VF) findings and circumpapillary retinal nerve fiber layer (RNFL) thickness in a series of PD patients and normal controls, in order to assess possible retinal anatomical changes and/or ...
