  • Patent number: 11442072
    Abstract: The present disclosure relates to a method for measuring aggregation of low-density lipoprotein (LDL). The susceptibility of LDL to aggregate is an important factor regarding prognosis, diagnosis and surveillance of atherosclerotic cardiovascular diseases and cardiometabolic diseases, such as type 2 diabetes and related conditions, at various stages of their development. Also provided are methods of treatment of such diseases in subjects in need thereof.
    Type: Grant
    Filed: July 1, 2019
    Date of Patent: September 13, 2022
    Assignee: Jenny and Antti Wihuri Foundation
    Inventors: Katariina Öörni, Maija Ruuth, Petri Kovanen

  • Patent number: 8415324
    Abstract: Heparin-like compounds inhibit collagen-induced platelet aggregation in flowing whole blood. The compounds share properties displayed by native mast-cell derived heparin proteoglycans (HEP-PG) and/or heparin glycosaminoglycan (HEP-GAG) molecules. The compounds are useful in prevention and treatment of severe vascular disorders including arterial thrombosis.

  • Patent number: 8163734
    Abstract: The invention concerns the use of a mast cell activation- or degranulation-blocking agent in the manufacture of a medicament for preventing and treating cerebral complications caused by thrombolytic treatment. The invention also relates to treatment of patients suffering from cerebral complications associated with thrombolysis. Further, the invention provides thrombolytic compositions comprising a mast cell degranulation-blocking and/or mast cell activation-blocking agent present in a therapeutically effective amount to prevent or reduce any cerebral complications caused by the active thrombolytic component.

  • Patent number: 7504113
    Abstract: The present invention is related to heparin-like compounds characterized by their capacity of inhibiting collagen-induced platelet aggregation in flowing whole blood and their use for prophylactic treatment of arterial thrombosis associated with vascular or microvascular injury and interventions. Said properties are related to a high coupling density of negatively charged heparin or heparin-like glycosaminoglycan molecules, present in multiple heparin or heparin-like glycosaminoglycans as well as in proteoglycans containing said multiple heparin or heparin-like glycosaminoglycans or lower-molecular-weight heparin or heparin-like glycosaminoglycans connected directly or through spacer/linker molecules to globular core molecules. Heparin-like compounds, with said properties are obtainable from mammalian mast cells, by tissue extraction or cell cultivation.
