A Mathematical Model of Platelet Aggregation in an Extravascular Injury Under Flow [PDF]

arXiv, 2020
We present the first mathematical model of flow-mediated primary hemostasis in an extravascular injury, which can track the process from initial deposition to occlusion. The model consists of a system of ordinary differential equations (ODE) that describe platelet aggregation (adhesion and cohesion), soluble-agonist-dependent platelet activation, and ...

Microrheology and structural quantification of hypercoagulable clots [PDF]

arXiv, 2023
We propose a combination of microrheological and structural characterizations of fibrin networks to study blood hypercoagulability. Fibrin is the central element of coagulation as its polymerization creates the network of fibers in which platelets and red blood cells are included.

Hypoxia modulates platelet purinergic signalling pathways. [PDF]

, 2019
BACKGROUND:  Hypoxia resulting from ascent to high-altitude or pathological states at sea level is known to increase platelet reactivity. Previous work from our group has suggested that this may be adenosine diphosphate (ADP)-specific. Given the clinical

Agkistrodon piscivorus piscivorus platelet aggregation inhibitor: a potent inhibitor of platelet activation. [PDF]

Proceedings of the National Academy of Sciences, 1989
Applaggin (Agkistrodon piscivorus piscivorus platelet aggregation inhibitor) is a potent inhibitor of platelet activation. The protein is isolated from the venom of the North American water moccasin snake in three steps, including gel filtration, cation exchange, and reverse-phase HPLC procedures.

Subpar reporting of pre‐analytical variables in RNA‐focused blood plasma studies

Molecular Oncology, EarlyView.
Pre‐analytical variables strongly influence the analysis of extracellular RNA (cell‐free RNA; exRNA) derived from blood plasma. Their reporting is essential to allow interpretation and replication of results. By evaluating 200 exRNA studies, we pinpoint a lack of reporting pre‐analytical variables associated with blood collection, plasma preparation ...

Synergistic effect of peptide inhibitors derived from the extracellular and intracellular domain of αIIb subunit of integrin αIIbβ3 on platelet activation and aggregation

Platelets, 2018
αIIbβ3, the major platelet integrin, plays a central role in hemostasis and thrombosis. Upon platelet activation, conformation of αIIbβ3 changes and allows fibrinogen binding and, subsequently, platelet aggregation.

Lipopolysaccharide as trigger of platelet aggregation via eicosanoid over-production [PDF]

, 2017
The effect of lipopolysaccharide (LPS) on platelet aggregation is still controversial. We performed in vitro and ex vivo studies in controls and in patients with community-acquired pneumonia (CAP) to assess the effect of LPS on platelet activation (PA ...

Identification of functional and diverse circulating cancer‐associated fibroblasts in metastatic castration‐naïve prostate cancer patients

Molecular Oncology, EarlyView.
Cancer‐associated fibroblasts (CAFs) promote cancer growth, invasion (metastasis), and drug resistance. Here, we identified functional and diverse circulating CAFs (cCAFs) in patients with metastatic prostate cancer (mPCa). cCAFs were found in higher numbers and were functional and diverse in mPCa patients versus healthy individuals, suggesting their ...

Aggregation of Red Blood Cells: From Rouleaux to Clot Formation [PDF]

Comptes Rendues en Physique 14, 459 (2013), 2013
Red blood cells are known to form aggregates in the form of rouleaux. This aggregation process is believed to be reversible, but there is still no full understanding on the binding mechanism. There are at least two competing models, based either on bridging or on depletion.

Surfaceome: a new era in the discovery of immune evasion mechanisms of circulating tumor cells

Molecular Oncology, EarlyView.
In the era of immunotherapies, many patients either do not respond or eventually develop resistance. We propose to pave the way for proteomic analysis of surface‐expressed proteins called surfaceome, of circulating tumor cells. This approach seeks to identify immune evasion mechanisms and discover potential therapeutic targets. Circulating tumor cells (
