A double-stranded secondary structure for hyaluronic acid in aqueous-organic solvent as revealed by vacuum ultraviolet circular dichroism

Creator:: Staskus, Paul
Abstract:: The association of hyaluronic acid (HA) into a double stranded structure has been investigated by circular dichroism (CD) spectroscopy into the vacuum ultraviolet region. The CD of HA changes dramatically, monitoring a cooperative transition as the dielectric constant of an aqueous solution is reduced by adding organic solvents. This structural...

The exploitation of methylthioadenosine phosphorylase deficiency in cancer therapy

Creator:: Lindburg, Katherine L.
Abstract:: Methylthioadenosine (MTA) is a naturally occuring nucleoside formed during the synthesis of polyamines in mammalian cells. MTA is rapidly catabolised by MTA phosphorylase (MTAase), eventually yielding methionine and adenine. MTAase has been shown to be active in all normal cells, but deficient in some cells and tissues of malignant origin....

Studies to improve lactic acid bacterial starter cultures

Creator:: Khosravi, Lewa
Abstract:: Three commercial sausage starter cultures were grown in an internal-pH-controlled medium (PHASE 4) and in a soluble phosphate-buffered medium. The cultures were tested by comparing viable counts before and after freezing at -40 C or freeze-drying and subsequent storage for 3 months in the frozen or dried state. Strains varied...

Studies on advanced intermediates in the biosynthesis of streptonigrin

Creator:: Erickson, W. Randal
Abstract:: Early studies on the biosynthesis of the quinoline quinone portion of streptonigrin, 1, had suggested the intermediacy of novel aromatic amino acids. In order to test this hypothesis, a series of compounds was synthesized and tested for potential incorporation. [4-¹⁵N] 4-Aminoanthranilic acid, 4 5 a , [4-² H] 7-aminoquinaldinic acid,...

A molecular study of the viral proteins of infectious hematopoietic necrosis virus

Creator:: Hsu, Ya-li
Abstract:: The virion protein patterns of 72 isolates of infectious hematopoietic necrosis virus (IHNV) were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of S-methionine labeled virus. This analysis led to the classification of these virus isolates into 4 or more types. Type 1 virus is characterized by a nucleocapsid protein...

Effect of dietary fat and cholesterol on plasma lecithin:cholesterol acyltransferase activity in man

Creator:: Farid, Sheedvash Amirkia
Abstract:: Effect of diets varying in amount of cholesterol and polyunsaturated to saturated fatty acid ratio (P/S) on plasma lipid levels and lecithin:cholesterol acyltransferase (LCAT) activity was determined in fourteen young adult male subjects during a 13-week experimental period in a crossover design. Control diet was fed for two weeks prior...

Attempted cloning of T4 phage ribonucleotide reductase

Creator:: Booth, Joseph
Abstract:: Ribonucleotide reductase is an important enzyme in the control of DNA replication within the cell. Ribonucleotide reductase exerts its control through enzymatic reduction of nucleoside diphosphates. The bacteriophage T4 enzyme is an example of the class of iron-requiring reductases which also includes E. coli and mammalian ribonucleotide reductases. The two...

Molecular cloning of infectious pancreatic necrosis virus and characterization of the coding capacity of the complementary DNA

Creator:: Huang, Manley T. F.
Abstract:: The two segments of double-stranded RNA (dsRNA) from infectious pancreatic necrosis virus (IPNV) were cloned into plasmid vector pUC8. Two distinct sets of overlapping clones were identified by restriction enzyme and Southern blot analysis. Each of these sets was shown, by Northern blot analysis, to be exclusively related to either...
