Metabolism of pyrrolizidine alkaloids by ruminal microbes

Creator:: Hovermale, Jeannette Talbot
Abstract:: The plant Senecio jacobaea (tansy ragwort) produces several macrocyclic pyrrolizidine alkaloids which cause irreversible liver cirrhosis. All of the pyrrolizidine alkaloids in Senecio jacobaea are macrocyclic diesters of the necine base retronecine, with the two most predominant being seneciphylline and jacobine. Unlike horses and cattle, sheep and goats are generally...

A new general method for the optimization of HPLC ternary of pseudo-quaternary mobile phases and the separation of two new metabolites of nefopam from greyhound urine

Creator:: Chen, Hsiao and Chen, Xiao
Abstract:: A new general method is developed for the optimization of HPLC ternary or pseudo-quaternary mobile phases which are represented by the trilinear coordinate system. This method can predict the global optimum of the mobile phase composition. The global optimum composition along each edge of the triangle and the corresponding selectivity...

Analytical chemistry of pentazocine metabolites produced by the greyhound

Creator:: Xiao, Guang
Abstract:: This thesis concerns itself mainly with analytical methods development and analytical applications in the field of drug metabolism studies. The determination of the analgesic pentazocine and its metabolites in the greyhound are studied. Pentazocine and all of its possible metabolites are isolated from the greyhound urine by a the multi-solvent...

Solid Solution Studies of Layered Honeycomb-Ordered Phases O3-Na3M2SbO6 (M = Cu, Mg, Ni, Zn)

Creator:: Schmidt, Whitney, Berthelot, Romain, Sleight, A. W., and Subramanian, M. A.
Abstract:: Complete solid solutions with the composition Na₃M₂₋ₓM’ₓSbO₆ where M, M’ = Cu, Mg, Ni, Zn have been synthesized by conventional solid state techniques and were investigated using X-ray diffraction, magnetism and optical measurements. All compositions crystallize in a monoclinic unit cell and exhibit a layered structure with a honeycomb cationic...

Deposition and characterization of transition metal oxides from aqueous solution

Creator:: Betterton, Sharon A.
Abstract:: The aqueous chemistries of two transition metal cations, Zr⁴⁺ and Nb⁵⁺, are examined and then used to develop inorganic precursor solutions. The oxides of these cations (ZrO₂ and Nb₂O₅) are deposited and characterized, and their morphological and optical properties discussed. Due to the obstacles created by niobium's aqueous chemistry, an...

Synthesis and study of transparent p- and n-type semiconductors and luminescent materials

Creator:: Park, Cheol-Hee
Abstract:: New transparent p- and n-type semiconductors and luminescent materials have been prepared and characterized. Synthesis, structures, optical and electrical properties of new chalcogenide fluoride p-type transparent semiconductors MCuQF (M=Ba, Sr; Q=S, Se, Te) are described. Band-gap tuning and improvement in conductivity through p-type doping are demonstrated in the family. The...
