Publication number: 20090054686Abstract: The present invention generally relates to the partial chemical neutralization of organic acids to make compositions used in animal nutrition. More particularly, the present invention relates to the use of a cooled reactor to prepare aqueous compositions of partially neutralized organic acids by a continuous or semi-continuous method of reacting an alkali with an organic acid dispersed or dissolved in an aqueous system. The alkali source is present in an amount less than the stiochometric amount required for complete neutralization of the organic acid.Type: ApplicationFiled: July 16, 2008Publication date: February 26, 2009Inventors: James Driggers, Stephen F.

Publication number: 20080249173Abstract: A method is provided for treating a patient suffering from apoptosis of tissue comprising administering to that subject a therapeutically effective amount of one or more ketogenic compounds such that a physiological ketosis is produced sufficient to arrest said apoptosis. Preferably the apoptosis is of cerebral tissue such as that associated with acute intractible seizures, particularly with status epilepticus. The method is also applicable to apoptosis associated with administration of topic stuimuli for treatment of cancer, that produced by viral infections, autoimmune diseases or Aquired Immuno Defficiency Syndrome. The ketosis produced is a state in which levels of one or both of acetoacetate and (R)-3-hydroxybutyrate concentrations in the mood of the subject such that their total concentration in the blood is elevated above the normal fed levels to between 0.1 and 30 mM.Type: ApplicationFiled: May 4, 2005Publication date: October 9, 2008Inventors: Keith Frank Martin, David John Heal, Elizabeth Jagger
