Platelet activation plays a critical role in thrombosis and hemostasis. Several pathophysiological situations lead to hemolysis, resulting in the liberation of free ferric iron-containing hemin. Hemin has been shown to activate platelets and induce thrombo-inflammation.

Article Synopsis
  • Nanopores are gaining popularity for their potential in sensing and creating biomimetic channels, with surface charges playing a key role in ion selectivity and conductance.
  • This study utilizes three-dimensional modeling to analyze how the length of charged nanopores and applied voltage affect ion conductance and selectivity, highlighting conditions where reducing pore length doesn't alter ion current.
  • The research reveals that ion concentration polarization (ICP) impacts ionic concentrations inside the nanopores, and it discusses scenarios where charged nanopores might conduct less current than uncharged ones, aiming to inform the design of efficient nanopores for various applications.

Background: Cardiac hypertrophy is characterized by remodeling of the myocardium, which involves alterations in the ECM (extracellular matrix) and cardiomyocyte structure. These alterations critically contribute to impaired contractility and relaxation, ultimately leading to heart failure. Emerging evidence implicates that extracellular signaling molecules are critically involved in the pathogenesis of cardiac hypertrophy and remodeling.

Background:  Platelets are anucleate cells that play an important role in wound closure following vessel injury. Maintaining a constant platelet volume is critical for platelet function. For example, water-induced swelling can promote procoagulant activity and initiate thrombosis.

The liver has the remarkable capacity to regenerate. In the clinic, regeneration is induced by portal vein embolization, which redirects portal blood flow, resulting in liver hypertrophy in locations with increased blood supply, and atrophy of embolized segments. Here, we apply single-cell and single-nucleus transcriptomics on healthy, hypertrophied, and atrophied patient-derived liver samples to explore cell states in the regenerating liver.
