Article Synopsis
- Platelet suspensions (PSs) stored at 4 °C demonstrate better hemostatic properties compared to those stored at room temperature (22 °C), as highlighted by recent studies.
- In a comparison of apheresis derived platelets (ADPs) and random platelet suspensions (RPSs), both types stored at 4 °C showed significantly higher thrombin generation and faster peak levels than those at 22 °C.
- The findings suggest that using different storage temperatures for PSs could be beneficial, particularly for improving outcomes in trauma patients experiencing bleeding.
Objective: In the last decade, substantial evidence has accumulated about the use of cryopreserved platelet concentrates, especially in trauma. However, little reference has been made in these studies to the morphological and functional changes of platelets. Recently platelets have been shown to be activated by cryopreservation processes and to undergo procoagulant membrane changes resulting in the generation of platelet-derived microparticles (PMPs), platelet degranulation, and release of platelet-derived growth factors (PDGFs).

In this study, we studied the magnitude of blood donor gain by using a re-entry mechanism in our Blood Bank of Gulhane Military Academy of Medicine.
Materials And Methods: Between January and May 2013, 5148 voluntary blood donors were screened by ELISA method for HBsAg, anti-HBc total and other screening markers, prospectively.
Background/aim: Currently, the provision of blood products largely depends on walking blood banks and limited amounts of stored blood with short shelf lives. We aimed to compare the efficacy of erythrocyte concentrate (ECs) by pre- and postfreezing in vitro tests.
Materials And Methods: In our study, 10 ECs were glycerolized, frozen, thawed, and then deglycerolized using the Naval Blood Research Laboratory method.

Objective: Transfusion of platelet suspensions is an essential part of patient care for certain clinical indications. In this pioneering study in Turkey, we aimed to assess the in vitro hemostatic functions of platelets after cryopreservation.
Materials And Methods: Seven units of platelet concentrates were obtained by apheresis.
Aim: To compare the prevalence of hepatitis viral markers among soldiers from Turkey, blood donors from Northern Cyprus, and soldiers from Northern Cyprus.
Methods: Hepatitis B surface antigen (HBsAg), anti-HCV and anti-human immunodeficiency virus (HIV) seroprevalence, HBV DNA, HCV RNA and HCV genotyping among soldiers from Turkey (group I), civil blood donors from Northern Cyprus (group II), and soldier candidates from Northern Cyprus (group III) were studied and compared to one another. In total, 17545 cases (13546 males and 3999 females with a mean age of 34.
