标 题:Dietary supplement and method for synthesis of same
发明人：WYNN JASON R
权利人:StrongCell LLC
摘要:A dietary supplement and method for synthesis of the same are disclosed. In one embodiment of the method, an NADH component is provided that includes at least partially microencapsulated nicotinamide having nicotinamide blended with water. A supplement component, such as collagen, coenzyme Q10, vitamins, and minerals, is provided. A mixed component, which is a liquid, is formed by mixing the NADH component with the supplement component at ambient conditions. The mixed component is subjected to a fill production process.

摘要:A dietary supplement and method for synthesis of the same are disclosed. In one embodiment of the method, an NADH component is provided which includes NADH from about 0.1% to about 0.5% blended with water from about 40% to about 84% both by weight of the dietary supplement. A supplement component from about 9% to about 99% by weight of the dietary supplement is also provided. The supplement component may include collagen in about 2% to about 10%, vitamins in about 0.00001% to about 3%, and minerals in about 0.000002% to about 0.5% all by weight of the dietary supplement. A mixed component is formed by mixing the NADH component with the supplement component at ambient conditions. The mixed component is a liquid at ambient conditions having a pH of less than 4.0. The mixed component is subjected to a cold fill production process.

权利人:HART CHERYLE RAM; GROSSMAN RONALD S; RAM HERBERT
摘要:Dietary supplements for treating a neurotransmitter deficiency include one or more precursors of the deficient neurotransmitter and a cofactor for activating in vivo enzymatic synthesis of the deficient neurotransmitter. The dietary supplements can also include an appropriate neurotransmitter, such as an amino acid. When administered through the oral mucosa, increases in levels of the deficient neurotransmitters and relief from deficiency symptoms are obtained.

标题 :Synthesis of taxanes in culture using pseudocalluscells
发明人：SMITH RICHARD J
权利人:ESCAGENETICS CORP
摘要:A method of synthesis of taxanes from pseudocallus of Taxus species, particularly T. baccata , and methods for pseudocallus production are described. Pseudocallus of the invention can be distinguished from callus tissue and cell suspensions by (1) its unique morphology which is characterized by an amorphous aggregation of cells lacking both differentiated tissues and clearly defined meristematic zones; by (2) very poor intercellular adhesion resulting in marked tissue friability; and by (3) relatively high initial rate of mass doubling. Production of taxanes is achieved by culturing the pseudocallus on support culture medium.
