Energy efficient apparatus employing energy efficient process schemes providing enhanced integration of gasification-based multi-generation and hydrocarbon refining facilities and related methods

Energy-efficient gasification-based multi-generation apparatus, facilities, or systems, and methods of modifying existing gasification-based multi-generation apparatus and the various conventional thermal coupling arrangements, are provided. Apparatus for managing waste heat recovery through integration of a gasification-based multi-generation facility or other multi-generation system with a hydrocarbon refining facility or other hydrocarbon refining system and methods of providing the respective integration are also provided. An exemplary apparatus includes an integrated site energy management system configured according to one or more process-based thermal coupling schemes comprising one or more thermal coupling arrangements between a gasification-based multi-generation system or facility and a hydrocarbon refining system or facility. The gasification-based multi-generation system or facility can include an acid gas removal system or plant configured to remove acidic contaminants from a raw syngas feed to thereby provide a treated syngas feed, the acid gas removal system or plant containing a separation section including a solvent regenerator, and a gasification system configured to generate the raw syngas feed from a carbon-based feedstock. The hydrocarbon refining system or facility can include an aromatics system or plant containing a xylene products separation section including one or more of the following: an Extract column and a Raffinate column. The integrated site energy management system can include a hot-water system extending between the separation section of the acid gas removal system or plant and the xylene products separation section of the aromatics system or plant, and a plurality of added heat exchanger units providing various advanced thermal coupling arrangements.

Regulatory T cells and their use in immunotherapy and suppression of autoimmune responses

Based upon a strong correlation between regulator T cells (Treg cells) and suppressing or preventing a cytotoxic T cell response, provided are methods for the production of ex vivo activated and culture-expanded isolated CD4+CD25+ suppressor Treg cells for the prevention or suppression of immune reactions in a host, particularly in a human host, and including autoimmune responses. The resulting ex vivo culture-expanded Treg cells provide a sufficient amount of otherwise low numbers of such cells, having long term suppressor capability to permit therapeutic uses, including the preventing, suppressing, blocking or inhibiting the rejection of transplanted tissue in a human or other animal host, or protecting against graft vs host disease. Also provided are therapeutic and immunosuppressive methods utilizing the ex vivo culture-expanded Treg cells for human treatment, and high efficiency methods for research use.

Compositions and methods of using a synthetic Dnase I

Compositions and method for making and using a synthetic bovine DNase I are disclosed. More particularly, the sbDNase I of the present invention is a versatile enzyme that cleaves DNA nonspecifically to release 5′-phosphorylated nucleotides. The sbDNase I molecules of the present invention find particular use in a wide range of molecular biology applications, including: degradation of contaminating DNA after RNA isolation; RNA clean-up prior to, or in conjunction with, RT-PCR after in vitro transcription; identification of protein binding sequences on DNA (DNase I footprinting); prevention of clumping when handling cultured cells; tissue dissociation and creation of fragmented DNA for in vitro recombination reactions.
