Assessing The Behavioral Impact Of Pyridostigmine Bromide In Rats, Noah A. Martin
Assessing The Behavioral Impact Of Pyridostigmine Bromide In Rats, Noah A. Martin
Honors Theses
Pyridostigmine bromide (PB) is an organophosphate (OP) nerve agent prophylactic used to protect warfighters against chemical warfare agents. OPs inhibit the neural enzyme acetylcholinesterase (AChE) in the brain. This leads to the buildup of acetylcholine, causing respiratory failure, seizures, and death. PB functions by inhibiting ~30% of peripheral AChE temporarily, protecting the enzymes so that the body is able to restore sufficient cholinergic function post-exposure. PB does not cross the blood-brain barrier, though it may still indirectly affect toxicity in the brain due to repeated AChE inhibition throughout treatment, or by inhibition of non-target ChE’s in the blood. The aim …
Fe(Iii) And Mn(Ii) Binding De Novo Designed Peptides And Their Oxidation With H2o2, Hannah Randall, Russ Upton
Fe(Iii) And Mn(Ii) Binding De Novo Designed Peptides And Their Oxidation With H2o2, Hannah Randall, Russ Upton
Honors Theses
Metalloenzymes perform a wide variety of reactions that are instrumental to the basic functions of life. Learning more about those enzymes–their structure, folding, active sites, and co-factors–can help to not only better understand the finer details of the chemical world, but also help provide answers and possible solutions to questions pertaining to alternative energy. Particulate Methane Monooxygenase (pMMO) is a metalloenzyme that oxidizes methane into methanol in the biological processes of some methanogenic bacteria, a valuable part of their process to obtain energy. One of its active sites, CuB, has a relatively unknown function. Heptad repeats of model enzymes have …
Purple Urine Bag Syndrome: Regulation Of Pyrimidine Enzymes, Ashley N. Broadway
Purple Urine Bag Syndrome: Regulation Of Pyrimidine Enzymes, Ashley N. Broadway
Honors Theses
Purple Urine Bag Syndrome, PUBS, is a unique condition that shows an interesting discoloration of the urine from women who have a chronic catheter. This study focused on the regulation of enzyme activities to determine the effects that may create an environment where PUBS is seen in patients with catheters. In this study, the reductive pyrimidine pathway was used to read out the bacteria Pseudomonas aeruginosa ATCC 15692. This microorganism expresses a pathway that synthesizes indoxyl from tryptophan. The bacteria strains were grown using various carbon and nitrogen sources. Concentrations of acetonitrile at 2 mM and 10 mM, concentrations of …
