The Regioselective Conjugation of the 15-nt Thrombin Aptamer with an Optimized Tripeptide Sequence Greatly Increases the Anticoagulant Activity of the Aptamer

open access: yesPharmaceutics, 2023
Currently, oligonucleotide therapy has emerged as a new paradigm in the treatment of human diseases. In many cases, however, therapeutic oligonucleotides cannot be used directly without modification.

Dynamic allostery in thrombin—a review

open access: yesFrontiers in Molecular Biosciences, 2023
Thrombin is a serine protease that catalyzes a large number of different reactions including proteolytic cleave of fibrinogen to make the fibrin clot (procoagulant activity), of the protease activated receptors (for cell signaling) and of protein C generating activated protein C (anticoagulant activity). Thrombin has an effector binding site called the

Anticoagulants and the propagation phase of thrombin generation. [PDF]

open access: yesPLoS ONE, 2011
The view that clot time-based assays do not provide a sufficient assessment of an individual's hemostatic competence, especially in the context of anticoagulant therapy, has provoked a search for new metrics, with significant focus directed at techniques

Contribution of septins to human platelet structure and function

open access: yesiScience, 2022
Summary: Although septins have been well-studied in nucleated cells, their role in anucleate blood platelets remains obscure. Here, we elucidate the contribution of septins to human platelet structure and functionality. We show that Septin-2 and Septin-9

Investigation of the heparin–thrombin interaction by dynamic force spectroscopy [PDF]

open access: yesBiochimica et Biophysica Acta (BBA) - General Subjects, 2015
The interaction between heparin and thrombin is a vital step in the blood (anti)coagulation process. Unraveling the molecular basis of the interactions is therefore extremely important in understanding the mechanisms of this complex biological process.In this study, we use a combination of an efficient thiolation chemistry of heparin, a self-assembled ...

Effect of Chinese herbal formulae (BU-SHEN-YI-QI granule) treatment on thrombin expression after ischemia/reperfusion

open access: yesAll Life, 2023
Bu-Shen-Yi-Qi granule (BSYQG), a Chinese herbal formula, has been used for the treatment of ischemic stroke with proven efficacy. The purpose of this study is to evaluate the therapeutic efficacy of BSYQG in neurovascular unit (NVU) and its mechanism of ...

A mathematical model to quantify the effects of platelet count, shear rate, and injury size on the initiation of blood coagulation under venous flow conditions.

open access: yesPLoS ONE, 2020
Platelets upregulate the generation of thrombin and reinforce the fibrin clot which increases the incidence risk of venous thromboembolism (VTE). However, the role of platelets in the pathogenesis of venous cardiovascular diseases remains hard to ...

Percutaneous Thrombin Injection Based on Computational Fluid Dynamics of Femoral Artery Pseudoaneurysms [PDF]

open access: yesKorean Journal of Radiology, 2021
To analyze the computational fluid dynamics (CFD) of femoral artery pseudoaneurysm (FAP), identify a suitable location and timing for percutaneous thrombin injection (PTI) based on this analysis, and report our clinical experience with the procedure.CFD can be used to analyze the hemodynamics of the human body.
