Selenomethionine and methionine in in vitro rabbit reticulocyte hemoglobin synthesis and in Escherichia coli tRNA aminoacylation

Creator:

McCoy, Kim Edward Monroe

Abstract:

Selenomethionine and methionine have been postulated to be similarly involved in protein synthesis. This thesis has evaluated this hypothesis from a molecular and genetic approach. Selenomethionine and methionine were incorporated into rabbit reticulocyte hemoglobin at the same rates and in equal quantities. Each methionine demonstrated competitive inhibition for its analog...

Glutathione peroxidase and selenium distribution in semen and reproductive tissues of farm animals

Creator:

Alabi, Nathaniel Sigismund

Abstract:

This study was conducted to investigate the distribution of glutathione peroxidase (GSH-Px) and selenium in semen of the boar, bull, ram and stallion, and in the reproductive tissues of the boar, bull and ram. The effect of repeated noncryoprotective freeze-thawing on GSH-Px activity was also studied. Both hydrogen peroxide (H₂0₂)...

Interaction of selenium with cadmium and mercury in semen and reproductive tissues: in vivo and in vitro studies

Creator:

Alabi, Nathaniel Sigismund

Abstract:

Studies were conducted to investigate the metabolism of selenium (Se) , and the influences of Se on the metabolism of cadmium (Cd) and inorganic mercury (Hg) in rats, and in ram semen in vitro. Se-deficient (-Se) or Se-adequate (+Se) rats were injected intraperitoneally with either ¹⁰⁹CdCl₂ (5 μCi/rat) or ²⁰³HgN0₃...
