Title: Novel peptide sy
Inventor: OOISHI YASUNORI
IPC: A23L1/305
Filed: 2002-12-24
Abstract: A peptide SY is produced by applying peptides, which have been obtained by treating fish meat with protease, to a peptide-adsorbing resin (ODS resin, etc.), then eluting successively with a 11 to 18 V/V % aqueous solution of ethanol and water, and combining a fraction (1) obtained after eluting with water and another fraction (2) obtained by eluting with the 11 to 18 V/V % aqueous solution of ethanol and water. Also, a peptide SY-MD is produced by isolating a fraction eluted with 11 to 18 V/V % aqueous solution of ethanol alone. The peptide SY and the peptide SY-MD are both novel peptide mixtures which contain a large amount of a newly found hypotensive peptide Val-Tyr, show little bitterness and have excellent taste and safety. Thus, these peptides are usable as hypotensive drugs, blood pressure increase inhibitors and functional foods aiming at preventing an increase in blood pressure.</SD OAB>

Inventor: BARTLETT PERRY FRANCIS
IPC: A61P25/16
Filed: 2002-05-31
Abstract: The present invention relates generally to a method for the generation of a substantially homogeneous population of undifferentiated cells. More particularly, the present invention relates to the purification of a substantially homogeneous population of stem cells and their progenitor or precursor cells. Even more particularly, the present invention provides a population of neural stem cells (NSCs). The subject invention is particularly directed to NSCs and precursor cells with the capacity to differentiate into cells and cell lineages required for the development, maintenance or repair of the central nervous system in an animal such as a mammal. The present invention is further directed to NSCs and progenitor and/or precursor cells which are capable of proliferation and differentiation into multiple cell lineages, such as but not limited to neurons, oligodendrocytes, glia and astrocytes. The subject invention further contemplates the use of NSCs and/or precursor cells for the repair or regeneration of tissue, such as tissue associated with the central nervous system, in an animal including a mammal.  The NSCs of the present invention may be used to identify naturally occurring molecules such as cytokines as well as molecules obtained from natural product screening or screening of chemical libraries which induce proliferation of the NSCs. Such molecules are useful in the development of therapeutics.

A conduit in a wellhead body member provides access to the vertical wellbore proximate the isolated tubing hanger. Hot electrical connection is made through the conduit, for electrical connection to the conducting tubing string. An electrical isolation assembly seals and electrically isolates the hot electrical connection in the conduit from the wellhead body members. Grounding connection is provided to the wellhead body member proximate the grounding tubing hanger. A source of current provides a first connection to the hot electrical connection and a second connection to the grounding connection.
