Abstract: Embodiments of the invention provide swallowable devices, preparations and methods for delivering drugs and other therapeutic agents within the GI tract. Many embodiments provide a swallowable device for delivering the agents. Particular embodiments provide a swallowable device such as a capsule for delivering drugs into the intestinal wall or other GI lumen. Embodiments also provide various drug preparations that are configured to be contained within the capsule, advanced from the capsule into the intestinal wall and degrade to release the drug into the bloodstream to produce a therapeutic effect. The preparation can be operably coupled to delivery means having a first configuration where the preparation is contained in the capsule and a second configuration where the preparation is advanced out of the capsule into the intestinal wall. Embodiments of the invention are particularly useful for the delivery of drugs which are poorly absorbed, tolerated and/or degraded within the GI tract.

Abstract: Methods are described for the isolation and selection of a heterogeneous bone marrow cell population, called NCS-01, that is effective at treating neurodegeneration. For example, NCS-01 cells are shown to treat neurodegeneration caused by ischemia. In vivo studies demonstrate that selected NCS-01 cell populations treat neurodegeneration in a standard rat middle cerebral artery occlusion (MCAO) animal model under conditions of transient or permanent total arterial occlusion. These studies also disclose that when the neurodegeneration is caused by ischemic stroke, combining the administration of a selected NCS-01 cell population with thrombolytic agents and/or mechanical methods of clot removal leads to a decrease in the volume of infarction caused by acute onset neurodegeneration. The disclosed cell therapy promises to make a significant clinical impact on patient survival after stroke.

Abstract: The disclosure describes compositions containing conjugates using novel linkers, bivalent polysaccharide conjugates, and methods of bivalent polysaccharide conjugation in the development of multivalent conjugate vaccines. Conjugation of capsular polysaccharides to carrier proteins is carried out using homo-bifunctional and/or hetero-bifunctional linkers of specific lengths. Incorporation of the linkers and their use in bifunctional linkers induces higher titers of functional antibodies with high avidity, eliciting higher immunologic memory, and reduced carrier protein effect. This provides immunochemically cross-reactive capsular polysaccharides wherein one or more cross-reactive capsular polysaccharides are conjugated sequentially or concurrently to carrier protein using bifunctional linkers bearing the same or different functional groups.
Abstract: A combined application of Haemophilus parasuis (HPS) LC strain having a deposit number of CGMCC No. 5257 and HPS LZ-20100109 strain having a deposit number of CGMCC No. 5802 in preparing a bivalent inactivated vaccine is provided, relating to HPS disease vaccines in a field of veterinary biologics. The combined application of the HPS LC strain and the HPS LZ-20100109 strain in preparing the bivalent inactivated vaccine is safe and reliable, providing not only a homologous challenge protection against serotype 1 and serotype 5, but also certain cross protection against heterologous challenges of serotype 2, serotype 4, serotype 10, serotype 12, serotype 13, serotype 14, and serotype 15 of HPS. The combined application of the HPS LC strain and the HPS LZ-20100109 strain has an obviously increased effect. After immunizing swine, a relatively strong immunity is generated; an incidence rate and a mortality rate of inoculated swine decrease obviously.

Abstract: The invention covers the use of certain classes of lipids including cationic lipids in ex-vivo dendritic cell therapies. The cationic lipids enhance antigen uptake, processing and presentation of the processed antigens by dendritic cells to CD8+ and CD4+ T-cells via the MHC classes I and II presentation pathways respectively. Antigen uptake via cationic lipid by dendritic cells result in significant lowering of the population of the immune suppressive regulatory T cells in the tumors and a significant increase of the tumor targeting cytotoxic T-cells. Loss of regulatory T cells and increase of tumor specific cytotoxic cells are conducive to effective elimination of the tumors.

Abstract: The present invention provides methods and compositions for the remote control of cell function based on the use of radiofrequency waves to excite nanoparticles targeted to specific cell types. The nanoparticles may be applied to the target cell extracellularly and/or expressed intracellularly. The cell type of interest expresses a temperature sensitive channel wherein excitation of the nanoparticles results in a localized temperature increase that is transduced into a cellular response. Such cellular responses may include, for example, increases in gene expression resulting in production of one or more physiologically active proteins. The expression of such proteins can be used to treat a variety of different inherited or acquired diseases or disorders in a subject. Accordingly, the invention provides a generic approach for treatment of any disease associated with a protein deficiency.
Abstract: This invention provides a system for producing cells of the hematopoietic lineage from embryonic stem cells. Differentiation is conducted in the presence of hematogenic cytokines and other factors listed in the disclosure.

Including a bone morphogenic protein during the differentiation process enhances the ability of the cell population to form secondary colonies. Because of the enormous replicative capacity of embryonic stem cells, this provides an important new commercial source of hematopoietic cells.
