No effective blood-flow enhancement therapies are available for patients with severe peripheral arterial disease (SPAD), thus amputation remains the only option for relief of rest pain or gangrene. Autologous bone marrow-derived stem cell therapy (ABMSCT) is an emerging modality to induce angiogenesis from endothelial progenitors. A total of 5 patients with(More)
BACKGROUND AND AIMS Amputation is the only current option for relief of rest pain or gangrene in patients with severe peripheral arterial disease. Up to now, no effective blood-flow enhancement therapies are available. Autologous bone marrow-derived stem cell transplantation is an arising therapy modality with an option of building new blood vessels through(More)
Essential thrombocythemia (ET) is an acquired myeloproliferative disorder with sustained increase of platelet count. This disease may be associated with thrombotic or bleeding complications due to the altered number and function of platelets. Coated-platelets produced by a simultaneous activation of collagen and thrombin represent a subpopulation of(More)
CONTEXT Lupus anticoagulant (LA) is a heterogeneous group of antiphospholipid antibodies. Among others, diluted prothrombin time (dPT) is a sensitive screening test for LA; however, the interpretation of LA tests is difficult in patients treated with anticoagulants. The effect of different types of anticoagulants on the result of LA tests, particularly on(More)
To routinely test the formation of thrombi and the effect of drugs modifying it, proper test systems are needed. Their design should rely on the laws of rheology and the physiology of laminar flow. To best model physiological or pathological shear conditions, parallel/linear and rotational type flow chambers are developed. We have compared the initial phase(More)
Stem cell therapy (SCT) is a promising and prospective approach in the treatment of patients with severe peripheral arterial disorders, primarily with Buerger's disease. However, very little is known about the duration of the effect of SCT, and to our best knowledge no data are available on the efficacy and safety of repeated SCT in patients with Buerger's(More)
The present study describes severe multiplex cerebral ischaemic laesions in a male patient being diagnosed with polycythaemia vera (PV). In contrast to previous publications, unique platelet receptor pattern with normal platelet count was identified. Glycoprotein Ib receptor number on the surface of resting platelets was increased two-fold and almost(More)
New sugar derivatives of ristocetin were prepared by copper-catalyzed 1,3-dipolar cycloaddition reaction using azido-ristocetin aglycon and various propargyl glycosides. Some of them were found to be active against gram-positive bacteria and showed favorable antiviral activity against the H1N1 subtype of influenza A virus.
