Crosstalk between Platelets and the Immune System: Old Systems with New Discoveries

Advances in Hematology, 2012
Platelets are small anucleate cells circulating in the blood. It has been recognized for more than 100 years that platelet adhesion and aggregation at the site of vascular injury are critical events in hemostasis and thrombosis; however, recent studies ...

Phytochemicalassay and Antiplatelet Activity of Fractions of Velvet Bean Seeds (Mucuna pruriens L.)

Hayati Journal of Biosciences, 2010
Platelet aggregation is an important factor contributing to the formation of thrombus due to an uncontrolled blood clotting. An antiplatelet agent is a compound which decreases platelet aggregation and inhibits thrombus formation.

3D Nano‐architected Polymer Shell Enables Reconfigurable Stabilized Blue Phase Soft Crystals

Advanced Functional Materials, EarlyView.
Spherical polymer shells featuring nanostructure of blue phase (BP) disclinations form via in situ photo‐polymerization within BP liquid crystals, providing controlled anchoring for BP nucleation and growth at room temperature and beyond. This architected confinement enhances BP thermal stability over a broad temperature range while enabling dynamic ...

Transport of platelets induced by red blood cells based on mixture theory [PDF]

arXiv, 2017
Thrombosis is a common complication following the surgical implantation of blood contacting devices, and is strongly influenced by the phenomenon of near-wall enrichment of platelets. This paper describes a multi-constituent continuum approach to study this phenomenon.

“Writing” Crystal Phases in Amorphous Calcium Carbonate via Laser‐Induced Patterned Transformations

Advanced Functional Materials, EarlyView.
Laser‐induced crystallization enabling the patterning of amorphous calcium carbonate into various distinct phases is introduced. This approach provides spatial control over polymorph selection, both crystalline and amorphous, inspired by biomineralization pathways.

Microneedle Assisted Melittin‐Chondroitin Sulfate Administration for the Transdermal Therapy of Rheumatoid Arthritis

Advanced Healthcare Materials, EarlyView.
Microneedle‐assisted RA therapy with MC complexes in CCMNP effectively treats cartilage degradation and synovitis without visceral damage. The dual capability in therapeutic intervention and in situ monitoring inflammation through local pH and ROS levels facilitates the dynamic adjustment of treatment protocols and represents a paradigm shift in the RA

Biomimetic Co‐delivery of Lenvatinib and FePt Nanoparticles for Enhanced Ferroptosis/Apoptosis Treatment of Hepatocellular Carcinoma

Advanced Healthcare Materials, EarlyView.
This study introduces a novel HCC treatment using poly lactic‐co‐glycolic acid (PLGA) nanoparticles encased in HCC cell membranes to co‐deliver Lenvatinib and FePt nanoparticles. This approach improves treatment efficacy by enhancing ferroptosis and apoptosis.

Treatment of critical bleeding events in patients with immune thrombocytopenia: a protocol for a systematic review and meta-analysis

Systematic Reviews
Background Critical bleeding events in adults and children with ITP are medical emergencies; however, evidence-based treatment protocols are lacking. Due to the severe thrombocytopenia, (typically platelet count less than 20 × 109/L), a critical bleed ...

Cooperative SIR dynamics as a model for spontaneous blood clot initiation [PDF]

arXiv
Blood clotting is an important physiological process to suppress bleeding upon injury, but when it occurs inadvertently, it can cause thrombosis, which can lead to life threatening conditions. Hence, understanding the microscopic mechanistic factors for inadvertent, spontaneous blood clotting, in absence of a vessel breach, can help in predicting and ...
