I was pleased to read Berber et al’s 50 year-old patient with Evans syndrome which was published as a Letter to The Editor in the recent issue of the Journal of Turgut Ozal Medical Center (2013;20(3):289-290). But, it was surprised to me that mega dose methyl prednisolone (MDMP) treatment was not brought to attention which had been successfully used for these patients first time from our countr...

The mechanisms that regulate the incorporation and release of tissue factors (TFs) into cell-derived microparticles are as yet unidentified. In this study, we have explored the regulation of TF release into microparticles by the phosphorylation of serine residues within the cytoplasmic domain of TF. Wild-type and mutant forms of TF, containing alanine and aspartate substitutions at Ser253 and S...

The effect of the various glycosyltransferases on glycosphingolipids was examined, using transfected swine endothelial cell (SEC) lines. The reactivity of parental SEC to normal human serum (NHS) and Griffonia simplicifolia IB(4) (GSIB4) lectin, which binds to the Gal alpha1-3 Gal beta 1-4 GlcNAc-R (alpha-galactosyl epitope), was reduced by approximately 20% by the treatment with D-PDMP (D-thre...

Background: Activated normal platelets undergo many biochemical and morphological changes, some of which are apoptotic. Platelet derived microparticles and shrinked platelets as hallmark of platelet activation and apoptosis disperse surfaces containing procoagulant activity around injured vessels and tissues. This study was conducted to determine microparticles formation and platelet shrinkage ...

Preparations of platelet concentrates (PCs) that are stored under blood bank conditions and used for transfusion purposes, appear to be enriched in platelet derived-microparticles (PMPs) with high coagulant activity that may change platelet efficacy and safety issues. High shear stress could cause shedding of PMPs from the platelet plasma membrane, platelet aggregation, and activation of the co...

BACKGROUND The tumor microenvironment has been described as a critical milieu determining tumor growth and metastases. A pivotal role of metastasis-inducing S100A4 in the development of tumor stroma has been proven in animal models and verified in human breast cancer biopsies. Expression and release of S100A4 has been shown in various types of stroma composing cells, including fibroblasts and i...
