Abstract: Provided herein are placental perfusate, placental perfusate cells, and placenta-derived intermediate natural killer cells, and combinations thereof. Also provided herein are compositions comprising the same, and methods of using placental perfusate, placental perfusate cells, and placenta-derived intermediate natural killer cells, and combinations thereof, to suppress the growth or proliferation of tumor cells, cancer cells, and the like, and to treat individuals having tumor cells.

Abstract: Provided herein are methods of producing natural killer cells using a two-step expansion and differentiation method. Also provided herein are methods of suppressing tumor cell proliferation, of treating individuals having cancer or a viral infection, comprising administering the NK cells produced by the method to an individual having the cancer or viral infection.

Abstract: This is a system and method of organizing secured purchasing groups (SPGs) to reduce costs and risks for both buyers and sellers by forming binding purchase offers and by selling in volume. The method includes authoring a first buyer to establish an SPG with the buyer's own terms of purchase. Other buyers join the established SPG if they agree to the terms of the SPG. As the established SPG interests more and more buyers and enlists the buyers to become a member, it attracts potential sellers to sell to the buyers of the SPG. A binding purchase contract is established when a seller makes a commitment to sell to a buyer of the SPG. A deposit is required from both the buyer and the seller to deter fraud and to reduce risks. A secret code system helps further reduce fraud and disputes. A user rating system further encourages good community behavior. The results of the rating system are used throughout the system.

Abstract: Provided herein are methods of suppressing tumor cell proliferation, of treating individuals having cancer or a viral infection, comprising contacting the tumor cells, or administering to the individual, placental perfusate, placental perfusate cells, or natural killer cells, e.g., placenta-derived intermediate natural killer cells, with an immunomodulatory compound or thalidomide.

Abstract: Provided herein are methods of producing erythrocytes from hematopoietic cells, particularly hematopoietic cells from placental perfusate in combination with hematopoietic cells from umbilical cord blood, wherein the method results in accelerated expansion and differentiation of the hematopoietic cells to more efficiently produce administrable erythrocytes. Further provided herein is a bioreactor in which hematopoietic cell expansion and differentiation takes place.

Abstract: Provided herein are placental perfusate, placental perfusate cells, and placenta-derived intermediate natural killer cells, and combinations thereof. Also provided herein are compositions comprising the same, and methods of using placental perfusate, placental perfusate cells, and placenta-derived intermediate natural killer cells, and combinations thereof, to suppress the growth or proliferation of tumor cells, cancer cells, and the like, and to treat individuals having tumor cells.

Abstract: Provided herein are the production of vasculogenic or angiogenic cells from placental perfusate. Also provided are methods of treating an individual having a cardiac or vascular insufficiency, disease, disorder or condition comprising administering to said individual placental perfusate, placental perfusate cells, or combinations of placental perfusate or perfusate cells with placental or non-placental hematopoietic stem cells or adherent placental stem cells.

Abstract: A method for use in indexing video footage, the video footage comprising an image signal and a corresponding audio signal relating to the image signals, the method comprising extracting audio features from the audio signal of the video footage and visual features from the image signal of the video footage; comparing the extracted audio and visual features with predetermined audio and visual keywords; identifying the audio and visual keywords associated with the video footage based on the comparison of the extracted video and visual features with the predetermine audio and visual keywords; and determining the presence of events in the video footage based on the audio and visual keywords associated with the video footage.
