TSST-1 protein exerts indirect effect on platelet activation and apoptosis
Platelets, 2022 Thrombocytopenia or platelet dysfunction is a risk factor for severe infection. Staphylococcus aureus (S. aureus) releases a variety of virulence factors especially toxic shock syndrome toxin 1 (TSST-1), which may cause toxic shock syndrome. S.

Modeling of Polymer Clay Nanocomposite for a Multiscale Approach [PDF]
, 2008 The mechanical property enhancement of polymer reinforced with nano-thin clay platelets (of high aspect ratio) is associated with a high polymer-filler interfacial area per unit volume. The ideal case of fully separated (exfoliated) platelets is generally difficult to achieve in practice: a typical nanocomposite also contains multilayer stacks of ...

Circulating microRNAs as biomarkers and mediators of platelet activation
Platelets, 2022 Platelets are essential mediators of physiological hemostasis and pathological thrombosis. Currently available tests and markers of platelet activation did not prove successful in guiding treatment decisions for patients with cardiovascular disease ...

A megakaryocyte with no platelets: Anti-platelet antibodies, apoptosis, and platelet production
Platelets, 2012 Primary immune thrombocytopenia (ITP) and drug-induced thrombocytopenia (DITP) are disorders caused primarily by the presence of anti-platelet auto-antibodies (Abs). Hematologists have traditionally seen thrombocytopenia as the result of increased destruction of Ab-coated platelets by the reticuloendothelial system.

Platelets, 2022 Immune thrombocytopenia (ITP) is a condition that is distinct from thrombosis with thrombocytopenia syndrome (TTS) that may also occur after coronavirus disease 2019 (COVID-19) vaccinations.

The utility of flow cytometric platelet forward scatter as an alternative to mean platelet volume
Platelets, 2022 The use of mean platelet diameter (MPD) to classify inherited thrombocytopenia (IT) has been demonstrated in several studies. Alternatively, the mean platelet volume (MPV) may be used, but in macrothrombocytopenia this may not be available.

Anomalous Platelet Transport & Fat-Tailed Distributions [PDF]
arXiv, 2020 The transport of platelets in blood is commonly assumed to obey an advection-diffusion equation. Here we propose a disruptive view, by showing that the random part of their velocity is governed by a fat-tailed probability distribution, usually referred to as a L\'evy flight.

Platelets, 2022 MicroRNAs (miRNAs) are small, non-coding RNAs, able to regulate cellular functions by induction of mRNA degradation and post-transcriptional repression of gene expression.

Platelets, 2022 Impaired platelet production is a mechanism of immune thrombocytopenia (ITP). Morphological abnormalities of megakaryocytes (MKs) are sometimes observed in this disease.

Effect of tube diameter and capillary number on platelet margination and near-wall dynamics [PDF]
, 2015 The effect of tube diameter $D$ and capillary number $Ca$ on platelet margination in blood flow at $\approx 37\%$ tube haematocrit is investigated. The system is modelled as three-dimensional suspension of deformable red blood cells and nearly rigid platelets using a combination of the lattice-Boltzmann, immersed boundary and finite element methods ...
