A Study Of Clinical Outcomes Using Serum Albumin And Percentage Of Weight Loss Following Nutritional Intervention In Post-Operative Bariatric Patients., Jennifer Michelle Angus

Electronic Theses and Dissertations

The purpose of this study was to determine if post-operative serum albumin and percentage of weight loss improved in patients who received formalized pre-operative nutrition counseling. Nutrition intervention was measured quantitatively. A retrospective review of records was conducted on 77 RYGB patients (68 female subjects and 9 male subjects), ages 21-64, during January 2001 through January 2006.

The results indicated that patients who received pre-operative nutrition intervention had better clinical outcomes of serum albumin than those with no nutrition intervention from a registered dietitian. However, outcomes regarding percentage of weight loss varied. Both pre-operatively and at the 3 month post-operative …

The Effect Of Caffeine And Ethanol On Flatworm Regeneration., Erica Leighanne Collins

Electronic Theses and Dissertations

Flatworms, or planarian, have a high potential for regeneration and have been used as a model to investigate regeneration and stem cell biology for over a century. Chemicals, temperature, and seasonal factors can influence planarian regeneration. Caffeine and ethanol are two widely used drugs and their effect on flatworm regeneration was evaluated in this experiment. Non-toxic levels of caffeine, a stimulant, and ethanol, a depressant, were determined. The tails of the flatworms were removed and the regeneration stage was analyzed every 3 days for 15 days to see the effect of these drugs alone and in combination on regeneration. For …

Studies On A 50s Ribosomal Precursor Particle As A Substrate For Erm E Methyltransferase Enzyme In Staphylococcus Aureus ., Indira Pokkunuri

Electronic Theses and Dissertations

Erythromycin is a macrolide antibiotic that inhibits not only mRNA translation but also 50S ribosomal subunit assembly in bacterial cells. An important mechanism of erythromycin resistance is the methylation of 23S rRNA by erm methyl transferase enzymes. We are interested in investigating the true substrate for methylation because it is known from our work and the work of others that fully assembled 50S subunits are not substrates for methylation. We have published a model for 50S ribosomal subunit formation where, the precursor particle that accumulates in erythromycin treated cells is a target for methyl transferase activity. Current studies are aimed …
