Abstract: Aquaculture feeds include a combination of proteinaceous vegetable material and proteinaceous fish material. The vegetable and fish materials are combined with additives such as alcohol and reducing agents and heated at elevated temperatures to release oil and nutrients from the fish material. At least a portion of the oil is absorbed into the proteinaceous vegetable material to form a proteinaceous product from the mixture. Alcohol is removed from the mixture to form the aquaculture feed with enhanced protein digestibility and solubility. The aquaculture feed may include up to about 50 percent proteinaceous vegetable material and up to about 50 percent proteinaceous fish material.

Abstract: The invention relates to methods of using an apparatus to sequester thrombi (including emboli) from blood of an animal such as a human. The apparatus comprises a stepped or sloped separation element interposed between an inlet region and an outlet region of a void that can be filled with fluid. The void can be enclosed within a cover and fluid flow through the void engages cells and thrombi/emboli in a blood sample with the separation element. Only particles (e.g., blood cells) which have or can deform to have a characteristic dimension smaller than or equal to the distance between a step and the cover or body can pass onto or past a step. By selecting dimensions which permit blood cells, but not thrombi or emboli, to pass onto or past a step and passing fluid through the apparatus, thrombi/emboli can be sequested from the blood sample. The thrombi can be observed, removed, or treated to effect their degradation or lysis.
