Patent number: 6541003Abstract: A live attenuated human immunodeficiency virus type 1 (HIV-1) whose replication is not constitutive but is instead conditionally regulated (such that rounds of reverse transcription with accompanying potential for error are strictly limited) might yield a paradigm that minimizes evolution to virulence and facilitate vaccine development.

Here, we describe the design of constitutively inactive HIV-1 genomes (HIV-DoxT and HIV-DoxSp) which can be conditionally resuscitated to an active state by tetracycline or related analogues. The HIV-DoxT construct comprises an inactivating mutation engineered into TAR, thereby rendering the virus non-responsive to Tat, a 302-bp DNA fragment (TetopT) which contains the tet-operator ligated into a position upstream of the HIV TATAA box, in both the 5′ and 3′ LTRs, and a reverse tetracycline-controlled activator (RTTA) coding sequence in place of the nef coding region.Type: GrantFiled: July 25, 2000Date of Patent: April 1, 2003Assignee: Infectious Diseases FoundationInventor: Stephen M.

Patent number: 6541038Abstract: A method for treating wood, characterized by impregnating wood with a metal-containing treating agent containing lignin and/or lignin derivatives and a metal, a metal compound, and/or a metal ion and oxidizing and/or macromolecularizing of the lignin and/or lignin derivatives in the wood to fix the metal component in the wood, and wood and woody materials obtained by the treating method. According to the method of the present invention, while effectively utilizing lignins, lignosulfonic acids, or lignosulfonic acid salts, leaching of the metal component can be suppressed to a low level to thereby retain the effects due to the incorporation of the metal components for a prolonged period.Type: GrantFiled: May 25, 2000Date of Patent: April 1, 2003Assignee: SDS Biotech K.K.Inventors: Keijitsu Tanaka, Hirobumi Aoki, Takashi Echigo

Patent number: 6541039Abstract: The invention relates to nanoscale particles suited especially for use in tumor therapy by hyperthermia. Said particles comprise a (preferably superparamagnetic) iron oxide-containing core and at least two shells surrounding said core. The (innermost) shell adjoining the core is an envelope which comprises groups capable of forming cationic groups and is broken down by human or animal tissue at such a slow rate as to allow for association of the core surrounded by said envelope with the surface of cells and/or for absorption of said core into the inside of cells.Type: GrantFiled: December 20, 1999Date of Patent: April 1, 2003Assignee: Institut für Neue Materialien gem. GmbHInventors: Christoph Lesniak, Thomas Schiestel, Helmut Schmidt, Andreas Jordan

Patent number: 6541041Abstract: Crude drug extracts containing soluble silicon compounds as an effective component are obtained by subjecting a crude drug to extraction with water or an aqueous solvent, preferably at an alkaline pH. The crude drugs subjected to extraction to obtain the extracts may be derived from animals, plants, etc. The quality of the crude drug extract can be standardized using the soluble silicon compounds as an index. The soluble silicon compounds exhibit inhibitory action towards the production of plasma kallikrein. The amount of soluble silicon compounds in the dry extract may be used as an index whereby the quality of various crude drugs can be standardized which contributes to providing crude drug extracts having a stable or consistent quality. Consequently, the present invention greatly contributes to the appropriate standardization of pharmaceuticals.Type: GrantFiled: January 27, 2000Date of Patent: April 1, 2003Assignee: Nippon Zoki Pharmaceutical Co., Ltd.Inventor: Jin-emon Konishi

Patent number: 6541043Abstract: A composition and method for treating Attention Deficit/Hyperactivity Disorder (ADHD) is provided which can be used both with and without ethical drugs now used to treat ADHD. The composition contains dimethylaminoethanol (DMAE), omega 3-fatty acids, betaine, oligomeric proanthocyanidins (OPC), folic acid, vitamins C, E, B12, B6, B5 and beta-carotene and minerals (calcium, magnesium, zinc and selenium). Ethical drugs such as amphetamines, methylphenidate HCl and pemoline are known to control ADHD, but each has significant side effects when used in their therapeutic dose. When combining the composition with such ethical drugs, the amount of the ethical drug can be lowered below a level which causes undesirable side effects which is an important feature. Preferred compositions contain one or more of lecithin, choline, 5-hydroxytryptophan, tyrosine, Reishi Extract, Kava Extract, Gingko, Ginseng and St. John's Wort.Type: GrantFiled: August 28, 2001Date of Patent: April 1, 2003Assignee: DexGen Pharmaceuticals, Inc.Inventor: Philip C. Lang

Patent number: 6541044Abstract: A method of making an extract from kava-kava root includes drying the kava-kava root, and grinding the dried root to a powder. Compounds are extracted by contacting the ground root with CO2 at an extraction pressure of at least about 500 bar, and at a temperature of less than about 65° C. The dissolved kava-kava compounds are separated from the CO2 into at least a first fraction by collecting the carbon dioxide after extracting and decreasing the pressure to a predetermined first separation pressure lower than the extraction pressure, at a temperature sufficient to prevent the carbon dioxide from solidifying. A composition including a kava-kava extract comprises greater than about 70% kavalactone, greater than about 0.3% flavokawin, and preferably comprises about 30% flavokawin. The composition comprises substantially no solvent residue and includes a pharmaceutically acceptable carrier. The composition is taken orally for nutritinal supplementation in a substantially soft gel capsule.Type: GrantFiled: November 17, 2000Date of Patent: April 1, 2003Assignee: U.S. NutraceuticalsInventor: Fred B. Gregg, Jr.
