The Effects Of An Adenosine A(2a) Agonist As An Adjunctive Treatment To Alleviate Sensorimotor Gating Deficits In A Rodent Model Of Schizophrenia, Hannah Rauhuff
Undergraduate Honors Theses
The adenosine system has become a promising target for the treatment of schizophrenia due to its unique relationship with dopamine D2 receptors. Dopamine D2 receptors display heightened sensitivity in schizophrenia, and inhibition of these receptors has been shown to alleviate some of the psychotic symptoms of the disorder. Inhibition of adenosine A(2A) receptors has been shown to decrease dopamine D2 receptor sensitivity, making this receptor a potential target for treatment of the disorder. This effect occurs because adenosine A(2A) receptors form a mutually inhibitory heterodimeric complex with dopamine D2 receptors. The present study looked at the …

An Investigation Into Formulation And Therapeutic Effectiveness Of Nanoparticle Drug Delivery For Select Pharmaceutical Agents, Dustin Cooper
Electronic Theses and Dissertations
Drug based nanoparticle (NP) formulations have gained considerable attention over the past decade for their use in various drug delivery systems. NPs have been shown to increase bioavailability, decrease side effects of highly toxic drugs, and prolong drug release. Furthermore, polymer based, biodegradable nanodelivery has become increasing popular in the field of NP formulation because of their high degree of compatibility and low rate of toxicity. Due to their popularity, commercially available polymers such as poly lactic acid (PLA), poly glycolic acid (PGA) and polylactic-co-glycolic acid (PLGA) are commonly used in the development and design of new nano based delivery …
Cytotoxic Effects Of Ruthenium Compounds On Human Cancer Cell Lines., Katie Beth Brown
Cytotoxic Effects Of Ruthenium Compounds On Human Cancer Cell Lines., Katie Beth Brown
Electronic Theses and Dissertations
Chemotherapy is the most common cancer treatment. Traditionally, platinum-based drugs are used in chemotherapy. More recently, researchers have focused on ruthenium based compounds as a substitute for the platinum compounds. Ruthenium-based compounds appear to be less toxic to healthy cells than traditional platinum-based compounds. In this study, 7 ruthenium-based compounds were tested on HT-29 (colon) and MCF-7 (breast) human cancer cell lines with the specific aim of determining whether or not any of the ruthenium-based compounds exhibited cytotoxic properties. In addition, levels of vascular endothelial growth factor (VEGF) production were tested in supernate from the cancer cells treated with various …
Characterization Of A 30s Ribsomal Subunit Intermediate Found In Escherichia Coli Cells Growing With Neomycin And Paromomycin., Cerrone Renee Foster
Characterization Of A 30s Ribsomal Subunit Intermediate Found In Escherichia Coli Cells Growing With Neomycin And Paromomycin., Cerrone Renee Foster
Electronic Theses and Dissertations
The bacterial ribosome is a target for inhibition by numerous antibiotics. Neomycin and paromomycin are aminoglycoside antibiotics that specifically stimulate the misreading of mRNA by binding to the decoding site of 16S rRNA in the 30S ribosomal subunit. Recent work has shown that both antibiotics also inhibit 30S subunit assembly in Escherichia coli and Staphylococcus aureus cells. This work describes the characteristics of an assembly intermediate produced in E.coli cells grown with neomycin or paromomycin. Antibiotic treatment stimulated the accumulation of a 30S assembly precursor with a sedimentation coefficient of 21S. The particle was able to bind radio labeled antibiotics …
