Vox Sanguinis, 1992
An immune response to human platelet antigens (HPA), as in neonatal alloimmune thrombocytopenia (NAIT) and post-transfusion purpura (PTP), is the exception rather than the rule and evidence is accumulating for the importance of human leucocyte antigen (HLA) class II restriction in this situation.

Platelet aggregation by platelet-clumping substance
Thrombosis Research, 1974Abstract The platelet-clumping substance isolated from rabbit plasma by the authors aggregated washed rabbit platelets, while ADP did not. The presence of AMP or adenosine did not inhibit the appearance of platelet aggregation induced by the clumping substance.

Platelet Economy (Platelet Survival and Turnover)*
British Journal of Haematology, 1966Investigators studying blood platelet survival and turnover have used the term ‘thrombo‐kinetics’ to describe the subject, by analogy with the usages of thermodynamics. Inasmuch as these phenomena reflect the interactions and hazards which the platelets encounter while discharging their function in the circulation, we prefer the term ‘platelet economy’

Biological Trace Element Research, 1988
Blood and its main components are commonly used to detect states of selenium deficiency. In order to examine whether human platelets are able to provide better or additional information, improvements of the analytical method resulted in surprisingly narrow normal ranges for selenium and other mineral elements using neutron activation analysis (NAA) and

Structural characterization of platelets and platelet microvesicles
Cell and Tissue Biology, 2016© 2016, Pleiades Publishing, Ltd.Platelets are blood cells without nuclei, which, in conjunction with fibrin, cause bleeding to stop (hemostasis). Cellular microvesicles are microscopic particles released into extracellular space under activation and/or apoptosis of cells of different types.

Annals of the New York Academy of Sciences, 1991
The role of platelets in arterial and venous haemostasis is well documented1, as is the contribution of these blood elements to arteriosclerosis2. Whether platelets contribute significantly to other pathological process, such as elimination of parasites3, localisation of tumor metastases4 and asthma5 is currently a matter for debate.

Status of Platelet Collection and Platelet Transfusion
Therapeutic Apheresis, 2001Abstract: Platelet product derived from single donor plateletpheresis is required to reduce the risks of adverse reactions by blood transfusion. The objectives of this study are to evaluate the status of platelet collection and its efficacy by various kinds of plateletpheresis equipment and to assess the achievement of platelet transfusion by platelet ...

Platelet Aggregometry and Anti-Platelet Isoantibodies
Pathophysiology of Haemostasis and Thrombosis, 1975102 sera from polytransfused patients have been screened in platelet aggregometry. Anti-human platelet isoantibodies, tested against ‘responsive’ human platelets in PRP, give in the aggregometer a decrease in optical density recorded as a sigmoidal curve.

Platelet substitutes and novel platelet products
Expert Opinion on Investigational Drugs, 2000Despite many advances in the safety, processing and storage of conventional 22 degrees C liquid-stored allogeneic platelet concentrates, there are still significant drawbacks to standard platelet concentrates used in transfusions for patients with thrombocytopenia.

Platelet aggregation and platelet-inhibiting drugs
Neurochemical Pathology, 1987Platelet function may cause a progression of central gray matter damage after cerebrospinal hemorrhage or trauma because of the thrombotic occlusion of injured vessels or a vasospasm induced by extravasated blood. It has therefore been suggested that antiplatelet drugs could limit the extent of the neurological lesions produced by a spinal trauma.
