Platelet Counts in Insoluble Platelet-Rich Fibrin Clots: A Direct Method for Accurate Determination

Platelet-rich fibrin (PRF) clots have been used in regenerative dentistry most often, with the assumption that growth factor levels are concentrated in proportion to the platelet concentration. Platelet counts in PRF are generally determined indirectly by platelet counting in other liquid fractions. This study shows a method for direct estimation of platelet counts in PRF. To validate this meth...

A method for rapid fractionation of particulate systems by gradient differential centrifugation.

IPIT initial experiments on the fractionation of mitochondria into subparticulate constituents, it became apparent that for isolation of the particles, a method more satisfactory than the customary methods of differential centrifugation was needed. The subject of this report is a simple and rapid method for obtaining relatively uncontaminated preparations of particulate cell components by gradi...

A Novel and Accurate Method for the Design of Dielectric

The development of numerical techniques now permits us to analyze complex structures such as dielectric resonator filters and planar passive elements for coplanar monolithic microwave integrated circuits. In this paper, we describe a novel method for designing dielectric resonator filters. Then a Chebychev band pass filter is designed by coaxially placing high-Q TM01Q dielectric resonators ...

A REPORT OF RAPID AND EFFICIENT METHOD FOR MITOCHONDRIAL DNA

Based on the similarity of prokaryotic DNA to that of mitochondrial DNA, a rapid and efficient method for DNA purification from mitochondrial extracts obtained from different sources, was carried out based on the modification method described by Marmur (1983) which resulted in a high degree of purity (A260/A280=2). In addition we have applied the same technique for the first time to purify...
