Glyphosate Catabolism By Pseudomonas Sp. Pg2982., Dean Lee Shinabarger Jan 1986

Glyphosate Catabolism By Pseudomonas Sp. Pg2982., Dean Lee Shinabarger

LSU Historical Dissertations and Theses

The pathway for the degradation of glyphosate (N-phosphonomethylglycine) by Pseudomonas sp. PG2982 has been determined using metabolic radiolabeling experiments. Radiorespirometry experiments utilizing 3-('14)C glyphosate revealed that approximately 50-59% of the C3 carbon was oxidized to CO(,2). Fractionation of stationary phase cells labeled with 3-('14)C glyphosate revealed that from 45-47% of the assimilated C3 carbon is distributed to proteins and that the amino acids methionine and serine are highly labeled. The nucleic acid bases adenine and guanine received 90% of the C3 label that was incorporated into nucleic acids, and the only pyrimidine base labeled was thymine. These results indicated that …

Fear Of Crime And Women: An Analysis Of A Paradox (Louisiana)., Cheryl L. Thayer-Doyle Jan 1986

Fear Of Crime And Women: An Analysis Of A Paradox (Louisiana)., Cheryl L. Thayer-Doyle

LSU Historical Dissertations and Theses

Research indicates that sex is the most powerful predictor of fear of crime and that women have a higher level of fear than men. A paradox arises because women have a higher level of fear but are victimized less. This dissertation examines: (1) the underlying dimensions of fear and the specific offenses that evoke fear in men and women; (2) selected social and demographic characteristics and their relationship to a criterion variable; and (3) the effect the fear of rape contributes to the differences in the level of fear between men and women. The data was taken from a larger …

The Type A Behavior Pattern And Acth Response To The Stress Of Cardiac Catheterization., Marie Carmen Veitia Jan 1986

The Type A Behavior Pattern And Acth Response To The Stress Of Cardiac Catheterization., Marie Carmen Veitia

LSU Historical Dissertations and Theses

There is substantial evidence to indicate that the Type A Behavior Pattern is associated with an increased risk of coronary heart disease. Recent research has shown that Type As, as compared to Type Bs, demonstrate enhanced biochemical and cardiovascular responses to stressful situations. These findings have led researchers to postulate that physiological reactivity may be one of the mechanisms through which Type A behavior confers coronary risk. The present study was designed to investigate physiological and psychological reactivity in Type A and Type B cardiac patients exposed to a cardiac catheterization. The effects of drugs (i.e., none versus beta-blockers and …

The Biology Of Egg Production In The House Cricket, Acheta Domesticus L., Craig William Clifford Jan 1985

The Biology Of Egg Production In The House Cricket, Acheta Domesticus L., Craig William Clifford

LSU Historical Dissertations and Theses

Oogenesis commenced on day 3 (day 0 = adult ecdysis) in Acheta domesticus L., which, based on degeneration of the flight muscles, was approximately when juvenile hormone was released. Starvation did not prevent the onset of oogenesis, although egg production was greatly reduced. Virgin females did not oviposit and the oviducts filled with eggs by day 15. Compaction appeared to be a factor limiting oogenesis. The digestive tract was compressed and feeding reduced, which might be the primary factors terminating oogenesis. The concentration of juvenile hormone esterase (JHE) did not change as virgins filled with eggs, which indicated that JHE …

Host Responses To The Phenolic-Glycolipid-1 Antigen Of Mycobacterium Leprae (Elisa, Leprosy, Epidemiology, Armadillo, Human)., Richard W. Truman

LSU Historical Dissertations and Theses

Antibody responses to the apparently species specific phenolic-glycolipid-1 (Phen-Gl-1) antigen of Mycobacterium leprae were examined in humans and armadillos using enzyme-linked immunosorbent assays (ELISA). Statistical definitions for the interpretation of positive and negative reactions were derived. A retrospective serological survey of armadillos indicated that leprosy in the wild armadillo is a naturally acquired zoonosis. Presently 12.5% of the armadillos in 2 parishes in south central Louisiana have detectable IgM antibodies to Phen-Gl-1. Approximately 2.7% of these histologically exhibit clinical disease. Antibodies were not detected in Florida armadillo sera. Variations in prevalence rates were noted, and may be due to environmental …

Characterization Of The Modified Phagocytic Vacuole Occupied By Intracellular Toxoplasma Gondii (Macrophage, Protozoa)., L. David Sibley Jan 1985

Characterization Of The Modified Phagocytic Vacuole Occupied By Intracellular Toxoplasma Gondii (Macrophage, Protozoa)., L. David Sibley

LSU Historical Dissertations and Theses

Toxoplasma gondii is a protozoan parasite which resides in modified endocytic compartments of host cells. Extensive intracellular replication and host cell lysis leads to acute toxoplasmosis which is eventually limited by the host immune response to a chronic state of infection. The features of this unique intracellular compartment, which enables Toxoplasma to survive in macrophages, are reported here. Although Toxoplasma survives in normal macrophages, activated macrophages from immune animals rapidly killed Toxoplasma by production of oxygen radicals and intermediates generated during parasite invasion. In addition, activated macrophages inhibited Toxoplasma growth by an oxygen-independent mechanism. Qualitative and quantitative features of oxygen …
