Viral inactivation in platelet concentrates
Transfusion Clinique et Biologique, 1994Although the current risk of posttransfusion infection is very low in North America and Western Europe, there continues to be considerable interest in measures to inactivate residual viruses in blood components. The human immunodeficiency virus is of greatest concern, but hepatitis C virus is also considered to be a significant problem.

Platelet concentration and platelet volume distribution in healthy cats
American Journal of Veterinary Research, 1984SUMMARY An electronic particle counter and size analysis system were used to determine platelet count, mean platelet volume (mpv), platelet volume heterogeneity (sd of platelet volumes), and platelet mass values in feline platelet-rich plasma (prp) prepared by brief centrifugation of blood.

Platelet counting using plasma platelet concentrate samples
Transfusion Medicine, 1992SUMMARY. Platelet counting using samples of plasma from platelet concentrates prepared for transfusion was assessed. The methods employed included a manual phase‐contrast method, and counting with Coulter S Plus and Sysmex E‐2500 counters. All methods were reproducible (mean CV of 4.9, 2.2 and 1.4%, respectively).

Preservation of platelet function in cryopreserved platelet concentrates with prostacyclin
Clinical & Laboratory Haematology, 2008Prostacyclin (Epoprostenol) or a stable prostacyclin analogue (ZK 36,374) were added to platelet concentrates prior to cryopreservation. This resulted in significantly better preserved function of the thawed platelet concentrate, assessed by platelet aggregation to various concentrations of ADP, collagen and ristocetin, compared to control ...

Monitoring of platelet morphology during storage of platelet concentrates
Transfusion, 1989During storage, human platelet concentrates progressively lose the capacity to survive and function in vivo after transfusion. A shape transformation from disc to sphere is the most reliable in vitro determinant for the loss of the in vivo survival of platelets.

The Functional Integrity of Platelets in Volume-Reduced Platelet Concentrates
Anesthesia & Analgesia, 2005Premature and low-birth-weight infants usually require small-volume platelet transfusions to treat thrombocytopenia. Also, infants undergoing open-heart surgery with extracorporeal circulation and with compromised cardiac function are at risk for excessive intravascular volume.

Platelet apoptosis in stored platelet concentrates and other models
Transfusion and Apheresis Science, 2003Apoptosis or programmed cell death was discovered in nucleate cells 30 years ago and has been well documented. In contrast, apoptosis in anucleate platelets has only a five-year research history and as yet but few publications related to it. In this review, we will present the data on platelet apoptosis in several models.

A flow cytometric method for platelet counting in platelet concentrates
Transfusion, 2011BACKGROUND: The platelets (PLTs) in PLT concentrates are counted with hematology analyzers, but varying results among different hematology analyzers are observed, making comparisons very difficult. Due to the absence of red blood cells in PLT concentrates, the International Council for Standardization in Hematology (ICSH) reference method was modified ...
