Abstract:
We evaluated and compared the biomechanical properties of Leukocyte-and Platelet Rich Fibrin L-PRF clots and membranes derived from smoker and nonsmoker donors. Twenty venous-blood donors (aged 18 to 50 years) were included after signing informed consent forms. L-PRF clots were analyzed and then compressed to obtain L-PRF membranes. L-PRF clot and membrane samples were tested in quasi-static uniaxial tension and the stress–stretch response was registered and characterized. Furthermore, scanning electron microscope representative images were taken to see the fibrin structure from both groups. T

Objectives. The mechanical properties of membranes are important factors in the success of treatment and clinical handling. The goal of this study was to compare the mechanical properties of early leukocyte- and platelet-rich fibrin (L-PRF) versus PRGF/Endoret membrane.Materials and Methods.In this experimental study, membranes were obtained from 10 healthy male volunteers. After obtaining 20 cc venous blood from each volunteer, 10 cc was used to prepare early L-PRF (group 1) and the rest was used to get a membrane by PRGF-Endoret system (group 2).

Abstract:
Leukocyte and platelet-rich fibrin (L-PRF), an essential source of cytokines and growth factors, has been widely used to regulate the healing process. The quality of the L-PRF obtained is dependent on technical factors and the centrifugation protocol used. Thus, the present study aimed to macro and microscopically evaluate the formation of the L-PRF membrane/clot in two centrifuge models and protocols recommended by manufacturers. Four blood samples from 8 healthy volunteers undergoing rehabilitation surgery with dental implants were used. In group 1 of the Montserrat centrifuge (model 80-2B 1

Alternative pre-mRNA splicing is often controlled by cell signals (1-3). Membrane depolarization/calcium (Ca2+) signaling controls alternative splicing of a group of genes in neurons and endocrine cells (4-9), with important implications in memory formation or secretion of hormones and neurotransmitters (10-15). However, the underlying molecular basis remains largely unknown.

Since NAAG exhibits neuroprotective effects, GCPII may participate in a number of brain disorders, which were shown to be ameliorated by GCPII selective inhibitors.

Despite this long history, detailed data on the biochemistry of plasminogen activation have only become available recently.
