Kinetic Parameters of Platelet Aggregation as an Expression of Platelet Responsiveness
Thrombosis and Haemostasis, 1977SummaryThe kinetics of platelet aggregation induced by collagen and by ADP were studied. The maximum aggregation (ΔLTmax) and the ADP and collagen concentrations required to produce half-maximum aggregation (Kd) were determined using platelets obtained from normal individuals, individuals who ingested aspirin and individuals whose platelet-rich plasma (

Determination of Critical Parameters in Platelet Margination
Annals of Biomedical Engineering, 2012An investigation of margination dependence on hematocrit, platelet shape, and viscosity ratio of plasma to cytoplasm is presented. Whole blood is modeled as a suspension of deformable red blood cells (RBCs) and rigid platelets in a viscous liquid. The fluid phase is simulated using the lattice-Boltzmann method, the RBC membranes are modeled with a ...

Expression of platelet parameters and platelet membrane glycoproteins in childhood Burkitt lymphoma
Leukemia Research, 2019Platelet activation and functional changes in some haematological malignancies have been investigated with little or no known documentation on Burkitt lymphoma (BL). Abnormalities of platelets contribute to either haemorrhage or thrombotic episodes which are life-threatening in patients with BL.

The value of first-trimester platelet parameters in predicting gestational diabetes mellitus
Journal of Maternal-Fetal & Neonatal Medicine, 2020Objective To explore the potential clinical value of platelet parameters in early pregnancy in predicting gestational diabetes mellitus (GDM). Methods A total of 1188 singleton pregnant women were included in the regular antenatal examination and ...

The mitochondrial membrane potential in human platelets: a sensitive parameter for platelet quality
Transfusion, 2004BACKGROUND: Deterioration of platelet (PLT) quality during storage is accompanied by an increase in lactate production, indicating a decrease in mitochondrial function. In this study, the optimal conditions under which the fluorescent dye JC‐1 can be used to detect changes in mitochondrial function in PLTs were established.STUDY DESIGN AND METHODS ...

Automated Platelet-Sizing Parameters on a Normal Population
American Journal of Clinical Pathology, 1987The quantitation of platelets in peripheral blood is a well-recognized tool. However, other platelet parameters that recently have become available on a routine basis with the introduction of automated cell sizers may become increasingly important in evaluating the integrity of the thrombocytic function.

Platelet Parameters and Aggregation in Essential and Reactive Thrombocytosis
American Journal of Clinical Pathology, 1988Platelet characteristics were assessed in 15 patients with essential thrombocytosis (ET), 89 patients with reactive thrombocytosis (RT), and 23 normal controls. A platelet volume distribution width (PDW) greater than or equal to 10.5 was found in 50%, 21%, and 14% of the three groups, respectively (P = 0.01 between patients with ET and patients with RT;

Thrombosis Research, 1980
Abstract An additional parameter, the platelet count ratio (PCR), has been introduced to describe further platelet aggregation as determined by nephelometric measurements. This parameter is the ratio of the count of individual platelets a specified time after the addition of an aggregating agent to the original platelet count of the plateletrich ...

An important and overlooked parameter in platelet rich plasma preparation: The mean platelet volume
Journal of Cosmetic Dermatology, 2018SummaryBackgroundThe platelets are the most heterogeneous cellular elements of the blood in size whereas larger platelets have more granules that make them more reactive rather than their smaller counterparts.ObjectivesThe aim of this study is to report the distribution of platelets in the plasma after centrifugation steps.MethodsTwelve healthy male ...
