Patent number: 6080838Abstract: A peptidomimetic of the turn in the helix-turn-helix (HTH) motif of DNA-binding proteins was designed and synthesized. Conformational constraint was achieved by an unusual linking of two amino acids with a side-chain carbon--carbon bond. A phenyl ring provides the potential for new hydrophobic contacts with the hydrophobic core of the HTH motif. In the mimic, the peptide backbone and the central residue were retained in native form within a 12-membered cyclic tripeptide. The target compound 1b was synthesized by two sequential Horner-Wittig couplings followed by enantioselective hydrogenation with Rh(MeDuPHOS) in 8 steps and 35% overall yield. The stereochemical outcome of the key hydrogenation was determined by aromatic ring oxidation with RuO.sub.2 /NalO.sub.4 to give two equivalents of Boc-Asp-OMe.Type: GrantFiled: November 25, 1997Date of Patent: June 27, 2000Assignee: University of Virginia Patent FoundationInventors: Felicia A. Etzkorn, Jeremy M. Travins

Patent number: 6004932Abstract: The use of glucagon as a metabolic conditioner for dairy cows and other ruminants is described. The glucagon is preferably administered in an amount of from 1-10 mg per day, preferably during the time period beginning 7 days before calving and continuing until 21 days after calving. The administration of glucagon decreases the incidence of metabolic diseases and metabolic imbalances associated with fatty liver, allows cows to reach peak mile production sooner, and results in increased feed intake during the early stages of lactation.Type: GrantFiled: March 5, 1998Date of Patent: December 21, 1999Assignee: Iowa State University Research Foundation, Inc.Inventors: Jerry W.

Process and apparatus for the agglomeration of hydrolytically sensitive substances by means of steam
Patent number: 5955036Abstract: In the process for the agglomeration of slightly soluble and hydrolytically sensitive substances, a powder of the slightly soluble substance is conducted, together with at least one water-soluble binder, in free fall through a steam atmosphere at temperatures between 85.degree. C. and 105.degree. C. essentially without the action of compacting forces. In this process, the residence time in the steam atmosphere is approximately 0.5 to 10 seconds. The agglomerates formed are then dried in free fall, so that small solid bridges form from the binder liquid bridges formed at the points of contact between the primary particles. In a following integrated fluidized-bed dryer, the final drying then takes place to a water content of less than 0.5% by weight. The process is carried out in a steam jet agglomerator in which a freely falling product curtain of the pulverulent mixture to be agglomerated is impinged by steam using steam jet nozzles (5, 6).Type: GrantFiled: January 29, 1999Date of Patent: September 21, 1999Assignee: Bayer AktiengesellschaftInventors: Ina Seyffert, Hans Uhlemann, Reinhardt Walter, Joachim Martin Maasz -

Patent number: 5908921Abstract: The present invention is a process for the manufacture of gelatin which includes providing a collagen containing material and demineralizing the collagen containing material to produce ossein. The ossein is added to a water solution containing at least 3% sodium hydroxide or potassium hydroxide and at least 3% sodium sulfate for a time sufficient to form a reacted slurry. The reacted slurry is heated to a temperature of at least 45.degree. C. for a time sufficient to solubilize the ossein thereby producing a solution containing gelatin. The pH of the solution containing gelatin is raised to greater than 9.8. The pH of the solution containing gelatin is reduced with a sulfate salt of a divalent or trivalent metal to a neutral pH (between 7.0 and 8.0). The pH of the gelatin solution is then lowered to between 5.0 and 6.0 and a polymeric flocculant is added to the gelatin solution in an amount of less than 0.1% based on the dry weight of the gelatin to form a floc and the floc is removed.Type: GrantFiled: November 3, 1998Date of Patent: June 1, 1999Assignee: Eastman Kodak CompanyInventors: Scott W.
