Background: Inherited platelet disorders (IPDs) are rare diseases characterized by reduced blood platelet counts and/or impaired platelet function. (lu.se)
Platelets are also very important in maintaining this barrier function. (cdc.gov)
As you know, I think the most famous part about platelet function is the ability of your blood to clot. (cdc.gov)

DLL-4, in turn, instigated neighbouring platelets to switch to 'activated' phenotype through cleavage of Notch receptor and release of its intracellular domain (NICD), which was averted by inhibition of γ-secretase and phosphatidylinositol-3-kinase (PI3K). (elifesciences.org)
We established a method to assess the platelet phenotype on blood smears using immunofluorescence microscopy as a diagnostic tool for IPDs. (lu.se)

There is also a quantitative deficiency in the platelet protein multimerin 1 (MMRN1). (wikipedia.org)

If a prolonged aPTT or aPTT-LA is demonstrated, the patient's plasma is then subjected to another phospholipid dependent coagulation assay of a different principle. (medscape.com)

The frequency of CBC checks depends on how severely low the cat's blood-cell and platelet counts were and are, as well as the underlying cause of the disease. (petmd.com)

26 ] showed that gene expression of BDNF in lymphocytes and its protein expression in platelets from adult and pediatric depressed patients were significantly decreased, and the authors proposed that it could be a target for antidepressant drugs. (hindawi.com)

Platelets contain two unique types of granules: alpha granules and dense granules. (medscape.com)

Preoperative arterial blood gas analysis revealed desaturation with a Sao2 of 86% and Pao2 of 55 mmHg. (ispub.com)

On resting platelets, GP IIb/IIIa is unable to bind fibrinogen or vWf. (medscape.com)

How do functional platelet disorders manifest clinically? (arupconsult.com)

Our study presents compelling evidence in support of non-canonical juxtacrine Notch signaling within platelet aggregates that synergizes with physiological agonists to generate occlusive intramural thrombi. (elifesciences.org)

Once activated, platelets have two major mechanisms to recruit additional platelets to the growing hemostatic plug. (medscape.com)
Thus, the release reaction and prostaglandin synthesis act to consolidate the initial hemostatic plug by promoting the participation of other platelets in the growing hemostatic plug. (medscape.com)
The theoretical mechanism for the coagulation and hemostatic effects of rFVIIa are discussed. (medscape.com)

Blood products3 contribute to the saving of millions of lives every year, improve dramatically life expectancy and the quality of life of patients suffering from life-threatening conditions, and support complex medical and surgical procedures. (who.int)

Thus, Notch pathway can be a potential anti-platelet/anti-thrombotic therapeutic target. (elifesciences.org)
3 Blood products are defined as any therapeutic substances derived from human blood, including whole blood, labile blood components and plasma-derived medicinal products. (who.int)

Patients receiving granulocyte components, components that are HLA matched, or directed donations (from blood relatives) . (utmb.edu)

In fact, some antidepressants increase BDNF expression [ 27 ] and also may evoke BDNF release from platelets, in a dose-dependent manner after direct treatment in vitro [ 15 ]. (hindawi.com)
Screening with 2 or more phospholipid-dependent coagulation tests and demonstrating prolongation of at least one. (medscape.com)
