GALECTIN-3 PLASMAPHERESIS THERAPY
20190151360 · 2019-05-23 · ·

The invention is directed to the removal of serum gal-3 from circulation by plasmapheresis, comprising at least in part donor apheresis, using gal-3 binding agents in either a fixed bed, or in a form easily removed, such as by being complexed with magnetic particles. This method, on its own, brings a sharp reduction and relief from the inflammation and fibroses that can be induced by circulating gal-3. The process may be combined with the administration of gal-3 binding agents, such as modified citrus pectin, to further lower unbound gal-3 levels, to the point where gal-3 in the tissues may be addressed. This method may also be combined with removal of TNF receptors to provide an effective treatment for cancer.

20190134293 · 2019-05-09 ·

Provided is an accelerated method for preparing platelet rich plasma (PrP) without centrifugation or filtration. The method comprises contacting a sample of whole blood with an anti-coagulant and an inducer of Rouleaux formation; allowing the mixture to stand thereby depleting the sample of RBCs, and collecting the platelet-rich plasma fraction. The PrP volume obtained by the present method is about 10-60% of the volume of the starting whole blood sample, and contains less than 200,000 RBCs and at least 100,000 platelets per microliter.
