The Potential Roles of IL-1β, IL-6, and RIPK3 in the Pathogenesis of Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis.

Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis (SJS/TEN) are rare but severe skin conditions, often triggered by medications, that can be life-threatening. These conditions frequently affect the eyes, causing ocular surface disease, which can result in visual impairment or blindness. Although the exact mechanisms behind SJS/TEN remain unclear, key inflammatory mediators such as IL-1β, IL-6, and RIPK3 are believed to play critical roles in inflammation, necroptosis, and regulatory processes.

Fibrinolytic Status and Risk of Death After Acute Pulmonary Embolism.

Background: Acute pulmonary embolism (PE) is a heterogeneous disease process with variable presentation and outcomes. The endogenous fibrinolytic system is a complex framework of regulatory pathways that maintains homeostasis by dissolving overabundant thrombi. We sought to investigate phenotypic profiles of the endogenous fibrinolytic system among patients presenting with acute PE and their impact on mortality.

Potency Adjusted Blended Heparin of Bovine, Ovine, and Porcine Heparin Exhibit Comparable Biologic Effects to Referenced Single-Sourced Porcine Heparin.

Differential Neutralization of Apixaban, Betrixaban, Edoxaban, and Rivaroxaban by Andexanet Alfa as Measured by Whole Blood Thromboelastographic Analysis.

Introduction: The available oral anti-Xa agents are routinely used for the management of thrombotic disorders. A molecularly modified recombinant coagulation FXa, also known as Andexanet Alfa (AA), that has been developed as an antidote to neutralize the bleeding effects of oral FXa inhibitors, such as Apixaban and Rivaroxaban.

Materials And Methods: This study utilized thromboelastography (TEG 5000 Hemostasis System), to investigate the neutralizing effects of AA at different concentrations of oral FXa inhibitors measuring such parameters as R-Time, K-Time, Angle, and Max Amplitude (MA).

Prevention and treatment of atherothrombosis: Potential impact of nanotechnology.

Complications with atherosclerosis can often lead to fatal clot formation and blood vessel occlusion - also known as atherothrombosis. A key component to the development of atherosclerosis and atherothrombosis is the endothelium and its ability to regulate the balance between prothrombotic and antithrombotic activities. Endothelial surface glycocalyx has a critical role in maintenance of vascular integrity.

Predictive Role of Blood Cellular Indices and Their Relationship with Endogenous Glycosaminoglycans as Determinants of Inflammatory Biomarkers in Pulmonary Embolism.

Introduction: In this study, we profiled the levels of blood cellular indices, endogenous glycosaminoglycans (GAGs) and inflammatory biomarkers in a cohort comprised of pulmonary embolism (PE) patients, to determine their inter-relationships. Identification of this relationship may provide insight to the complex pathophysiology of PE and the predictive role of blood cellular indices in acute PE patients.

Materials And Methods: Plasma samples from PE patients and healthy controls were analyzed for thrombo-inflammatory biomarkers (IL-2, IL-4, IL-6, IL-8, IL-10, VEGF, IFN-ɣ, TNF-α, IL-1α, IL-1β, MCP-1, EGF, D-dimer, CRP and MMP-9) using biochip array and ELISA methods.

Differential Neutralization of Unfractionated Heparin and Enoxaparin by Andexanet Alfa.

Introduction: Andexanet alfa (andexanet) is an approved antidote used to reverse the bleeding effects of Direct Oral Anticoagulant (Direct-Xa agents) agents because it reverses anti-Xa activity.
