A Study Of The Environmental Aspects Of Schistosomiasis In Libya, Abubaker I. Swehli

Dissertations

Schistosomiasis is a serious disease in humans. Two species of schistosome, Schistosoma mansoni and Schistosoma haematobium, organisms that cause the disease, parasitize humans in Libya. Schistosomes require aquatic snails in their life cycle. The purpose of this study was to investigate the environmental and the host relationships of the disease in the three regions of Libya where the disease is found. These relationships include:

1) Analyses of the physical-chemical characteristics of the aquatic habitat.

2) Collection of snails to determine: a) the kind of snail species and th e ir abundance; and b) the cercarial infestation rates.

3) Infection rates …

Serial Cardiovascular Adaptations During Pregnancy, Mark Vincent Hart

Dissertations and Theses

Maternal cardiovascular adaptations appear to be essential in order to supply extra circulation to both the developing fetus and maternal system during a successful pregnancy. Since inadequate cardiovascular adjustments may produce abortions or maternal morbidity, the characterization of maternal cardiovascular changes during pregnancy and the elaboration of the underlying mechanism for these changes are essential to the understanding of how the heart enlarges during pregnancy and what significance this enlargement might have. To provide needed information regarding this time course and extent of maternal cardiac enlargement and the hormonal and hemodynamic changes which may be responsible for these changes, the …

The Absence Of Extrachromosomal Dna In Methanogenic Bacteria, Nancy Ann Kurkinen

Dissertations and Theses

Five species of methanogenic bacteria were analyzed for the presence of plasmid DNA. Several procedures for the detection and isolation of covalently closed circular plasmid DNA were modified for use with the methanogens.

Protein Contributions Of The Male Accessory Organs To The Composition Of Human Seminal Plasma As Determined By High Resolution Two-Dimensional Electrophoresis, Edward E. Gaunt

Theses and Dissertations in Biomedical Sciences

Human Seminal Plasma was evaluated using a High Resolution Two-Dimensional Electrophoresis technique adapted by this laboratory. Seminal plasma from healthy volunteers with recently proven fertility were characterized using this technique to establish "normal" protein distribution patterns in the two-dimensional polyacrylamide gel slab. In addition, time studies were performed on selected specimens to determine the effects of liquefaction on seminal plasma protein composition within the first several hours after collection. Split ejaculates were collected for identification and elaboration of accessory organ components in the whole seminal plasma specimen. A more direct approach to accessory organ component analysis involved electrophoresis of semen …
