As a leading cause of death worldwide, cancer and its treatments remain a primary source of interest among researchers. Modern studies are looking into bioselective cytotoxicity to create new chemotherapies that do not have the same harsh side effects as those we use today. Natural product research has a promising future for the development of such treatments. Specifically, polar flavonoids may be the key to a bioselective treatment. Such flavonoid species are native to plants, often within flower petals or within the body. A natural antioxidant, they are designed not to harm healthy cells. This study focuses on the plant …
Analysis Of The Role Of D2 Receptors In Methylphenidate-Induced Conditioned Place Preference., Chase M. Duty

ADHD is one of the most commonly diagnosed disorders during adolescence. Recently, significant increases in the diagnosis of ADHD have caused the prescription of the ADHD medication methylphenidate (MPH) to increase. MPH is a psychostimulant that blocks the dopamine transporter, which is responsible for dopamine reuptake at the synapse. The blockade of the dopamine transporter results in an increase in the availability of dopamine in the synaptic cleft. This increase of dopamine accounts for the addictive properties of a MPH due to strong effects on portions of the brain’s drug-reward pathway, including the striatum and nucleus accumbens. In this study, …
The Effect Of Caffeine And Ethanol On Flatworm Regeneration., Erica Leighanne Collins
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 …

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 …
