Pathogenicity of Heparin Dependent Antibodies
Many of the heparin dependent antibodies, including those with the IgG isotype, are asymptomatic, and only a subgroup of antibodies is positive in platelet activation assays. What differentiates pathogenic from asymptomatic antibodies is not fully understood, with the exception that there is some relationship between antibody concentration and occurrence of HIT, and that antibodies with the ...

A reliable rapid functional lab test to help in diagnosing heparin-induced thrombocytopenia (HIT) in daily practice
Recently brought under the spotlights because of the Astra-Zeneca anti-COVID 19 vaccine-associated thrombosis, HIT is a potentially life-threatening complication of treatment with anticoagulant heparin whose diagnostic work-up is still an issue. An article recently published in Biomedicines reported the performance of a rapid flow cytometry-based assay (FCA) as being like the performance of ...

Immune cells in Chernobyl radiation workers exposed to low dose irradiation
Immune response parameters were studied in Chernobyl radiation emergency workers exposed to low-dose irradiation during 1986–1989 and nuclear industry workers exposed under professional limits. Analysis was performed in irradiation dose limits of 250 and 100 mSv. The comparison group included participants of the clinical–epidemiological registry (n – 42,000) studied in the same time periods. The ...

Efficacy and Detection of Ceramide
Ceramides are composed of sphingosine analogs and long-chain fatty acids bound by amide bonds, and are the most important of the sphingolipid compounds. Ceramide is synthesized and secreted by lamellar vesicles, which together with cholesterol (25%) and free fatty acids (15%) constitute the intercellular lipids (ceramide 50%) involved in maintaining the skin barrier function. It also has various ...

Effect of endothelium mimicking self-assembled nanomatrices on cell adhesion and spreading of human endothelial cells and smooth muscle cells
Abstract The goal of this study is to develop unique native endothelium mimicking nanomatrices and evaluate their effects on adhesion and spreading of human umbilical vein endothelial cells (HUVECs) and aortic smooth muscle cells (AoSMCs). These nanomatrices were developed by self-assembly of peptide amphiphiles (PAs) through a solvent evaporation technique. Three PAs, one containing the ...
