A retrospective analysis of a commercially available platelet-rich plasma kit during clinical use.

Introduction: Point-of-care analyses of platelet-rich plasma (PRP) are not routine in the orthopedic regenerative medicine field. Therefore, many physicians rely on the manufacturer's reported content for commercial preparation kits. This contributes to a knowledge gap between injectate content and patient outcome.

NMR studies on the temperature-dependent dynamics of confined water.

We use (2)H NMR to study the rotational motion of supercooled water in silica pores of various diameters, specifically, in the MCM-41 materials C10, C12, and C14. Combination of spin-lattice relaxation, line-shape, and stimulated-echo analyses allows us to determine correlation times in very broad time and temperature ranges. For the studied pore diameters, 2.
