Analysis of platelet-rich plasma extraction variations in platelet and blood components between 4 common commercial kits [PDF]

open access: yes, 2017
Background: Platelet-rich plasma (PRP) has been extensively used as a treatment in tissue healing in tendinopathy, muscle injury, and osteoarthritis. However, there is variation in methods of extraction, and this produces different types of PRP. Purpose:

Effects of leukocyte–platelet-rich fibrin and advanced platelet-rich fibrin on the viability and migration of human gingival fibroblasts

open access: yesJournal of Indian Society of Periodontology, 2020
Platelet products play a fundamental role in the process of healing. The new generation of platelet-rich fibrin (PRF), namely advanced PRF (A-PRF), has different biological and mechanical properties compared to those of leukocyte-PRF (L-PRF). This study aimed to compare the effects of L-PRF and A-PRF on the viability and migration of human gingival ...

Blood clot inspired pore‐gradient nanofiber sponge with “outer filtration” and “inner adsorption” bifunction for rapid stop of uncontrolled hemorrhage

open access: yesBMEMat, EarlyView.
In this study, by mimicking the nanofiber structure and netting blood cells function of fibrin network in blood clots, we developed a novel bioinspired quaternized chitosan nanofiber sponge with distinct blood cell filtration and blood plasma absorption bifunction for rapid hemostasis.

Binding of thrombin-activated platelets to a fibrin scaffold through α(IIb)β₃ evokes phosphatidylserine exposure on their cell surface. [PDF]

open access: yesPLoS ONE, 2013
Recently, by employing intra-vital confocal microscopy, we demonstrated that platelets expose phosphatidylserine (PS) and fibrin accumulate only in the center of the thrombus but not in its periphery.

Multi-scale strain-stiffening of semiflexible bundle networks [PDF]

open access: yesarXiv, 2012
Bundles of polymer filaments are responsible for the rich and unique mechanical behaviors of many biomaterials, including cells and extracellular matrices. In fibrin biopolymers, whose nonlinear elastic properties are crucial for normal blood clotting, protofibrils self-assemble and bundle to form networks of semiflexible fibers.

Permeability and conductivity of platelet-reinforced membranes and composites [PDF]

open access: yes, 2001
We present large scale simulations of the diffusion constant $D$ of a random composite consisting of aligned platelets with aspect ratio $a/b>>1$ in a matrix (with diffusion constant $D_0$) and find that $D/D_0 = 1/(1+ c_1 x + c_2 x^2)$, where $x= a v_f/b$ and $v_f$ is the platelet volume fraction.

The Role of Platelet-rich Fibrin Facilitates the Healing of Gastrocnemius Muscle Defect: a Preliminary Study on Animal Model [PDF]

open access: yes, 2018
Background: Scar formation has been a classical issue in the healing of skeletal muscle defect which will results in decrease of strength and function. Platelet-rich plasma (PRP) has been studied to enhance the healing of muscle defect. The disadvantages

Developing an unfolding-incorporated coarse-grained polymer model for fibrinogen to study the mechanical behaviour [PDF]

open access: yesNortheast Journal of Complex Systems (NEJCS): Vol. 7 : No. 1 , Article 10 (2025); Special Issue: IC2SMA2 2025 Conference proceedings
Fibrinogen is a protein found in blood that forms Fibrin polymer network to build a clot during wound healing process when there is a cut in the blood vessel. The fibrin fiber is highly stretchable and shows a complex mechanical properties. The fibrin monomer, Fibrinogen, has a very complex structure which is responsible for its unusual elastic ...

Dynamic Formation of Preferentially Lattice Oriented, Self Trapped Hydrogen Clusters [PDF]

open access: yesarXiv, 2023
A series of MD and DFT simulations were performed to investigate hydrogen self-clustering and retention in tungsten. Using a newly develop machine learned interatomic potential, spontaneous formation of hydrogen platelets was observed after implanting low-energy hydrogen into tungsten at high fluxes and temperatures.

Conservative Surgical Treatment of Bisphosphonate-Related Osteonecrosis of the Jaw with Er,Cr:YSGG Laser and Platelet-Rich Plasma: A Longitudinal Study [PDF]

open access: yes, 2018
Introduction: The management of bisphosphonate-related osteonecrosis of the jaw (BRONJ), with no evidence-based guidelines, remains controversial. We aimed to evaluate the efficiency of a conservative surgical treatment combining Er,Cr:YSGG laser and ...
