Targeted apheresis to treat preeclampsia
11806459 · 2023-11-07 ·

This invention teaches a targeted apheresis method of treating a pregnant woman with preeclampsia, or who is predisposed to developing preeclampsia, utilizing immobilized binding agents contained within an apheresis device to remove sVEGFR-1 and sVEGFR-2, and one or more other harmful factors associated with preeclampsia selected from a list that includes: sEndoglin, Endothelin-1, TNF, IL-1, IL-6, IL-12, IL-18, digitalis-like factor, ouabain-like factor, marinobufagenin, .marinobufotoxenin, and telocinobufagin. The binding agents used are antibodies or aptamers or binding peptides. Reducing the concentration of sVEGFR-1, sVEGFR-2 and other harmful factors in the pregnant woman's blood using targeted apheresis will alleviate or delay the symptoms of preeclampsia, and thus postpone premature delivery of the baby so that the baby is born at term or as close to term as possible.

ECO-FRIENDLY SORBENT MATERIAL FOR REMOVING OIL AND METHOD OF PRODUCING THE SAME

Disclosed are a sorbent produced by recycling waste paper, which is an eco-friendly recycling paper resource, to adsorb and remove a marine spilled oil and other types of oil and a method of producing the same. The oil sorbent is produced by hydrophobizing a biomass material such as waste paper using a gas-grafting method. Compared to the oil sorbent of the prior art formed of synthetic resin, it is possible to provide excellent oil adsorption selectivity, a high oil adsorption rate, and a low water absorption rate. Therefore, an incineration process for processing the waste oil sorbent after use is easy advantageously. The oil sorbent generates less harmful substances during combustion because the eco-friendly material is used. Since a biomass material is hydrophobized using vegetable fatty acids, decomposition is performed fast within a short time in a landfill process, and there is no risk of environmental pollution.
