The Increased Effectiveness of Platelet Concentrates Prepared in Acidified Plasma

The increased effectiveness of platelet concentrates prepared in acidified plasma.

Comparative Study of Four Platelet-Rich Plasma Methods for Preparing Platelet Concentrates

Background: Platelet preparations have been used for a wide variety of clinical applications such as hemorrhage, tissue engineering and cellular therapy. Platelet concentrates can be prepared by the apheresis method or from the whole blood using the Buffy-coat or Platelet-rich plasma methods. The purpose of this study was to compare four variations of platelet-rich plasma method based on double...

Evaluation of microRNAs; mir223, mir222 and mir92a levels in the Platelet-derived microparticles in the Platelet concentrates produced by Platelet Rich Plasma method during storage

Abstract Background and Objectives Platelets release microparticles containing cellular components, including microRNAs, during storage. Assessment of these microRNAs is one of the markers for evaluation of platelet storage lesions. The aim of the present study was to evaluate the level of changes in the expression of mir-223, mir-92a and mir-222 during storage in platelets prepared by platele...

Evaluation of Biochemical Parameters of Platelet Concentrates Stored in Plasma or in A Platelet Additive Solution (Composol)

Abstract Objective Removing plasma from the platelet concentrate (PC) medium could be an effective way to increase the safety of this product. The goal of this study was to compare PC stored in plasma or in an additive solution (Composol) with in vitro testing. Materials and Methods Fifty-four single donor PCs were prepared from Iranian Blood Transfusion Organization (IBTO). Each PC unit wa...

Lipid composition of freshly prepared and stored platelet concentrates.

To evaluate the possibility that changes in lipid composition might be related to the functional lesion that develops when platelets are stored as concentrates for several days, we measured lipid constituents of platelets in freshly prepared concentrates and in concentrates stored for 72 hr at 4 degrees C or at 20 degrees C under standard blood banking conditions. At 20 degrees C, but not at 4 ...
