Potential Toxicity Of Silver Nanoparticles To Microbial Communities And Macroinvertebrates, Joseph Kusi
Potential Toxicity Of Silver Nanoparticles To Microbial Communities And Macroinvertebrates, Joseph Kusi
Electronic Theses and Dissertations
Silver nanoparticles (AgNPs) are the most common nanomaterials incorporated in commercial products due to their antimicrobial activity. Recently, AgNPs were detected in surface waters suggesting the potential for bioavailability in the aquatic receptor organisms. This dissertation research attempts to understand the potential toxicity of AgNPs on water quality indicators, focusing on the microbial community and amphipods. This study evaluated whether: (1) the antimicrobial properties of AgNPs pose potential risks to microbial communities in pathogen impaired streams; (2) AgNPs can cause a shift in functional diversity and metabolic fingerprinting of microbial communities; (3) survival and growth of Hyalella azteca (amphipods) could …
Therapeutic Drug Monitoring Of Apixaban Using Chromogenic Kits, Brooke Vogel
Therapeutic Drug Monitoring Of Apixaban Using Chromogenic Kits, Brooke Vogel
Undergraduate Honors Theses
Apixaban is a novel oral anticoagulant that prevents clotting by directly inhibiting Factor Xa in the coagulation cascade. Due to its different pharmacokinetics, previous standards for testing anticoagulant concentrations are ineffective at measuring apixaban. In this study, Hyphen Biomed Biophen Direct Xa Inhibitor and Biophen Heparin chromogenic kits from Aniara Diagnostica were used along with a NanoDrop™ One/OneC Microvolume UV-Vis Spectrophotometer to see if either of these kits provide acceptable precision and accuracy for the quantification of apixaban in plasma samples, as well as if there is a significant difference in these two kits at varying concentrations of apixaban. …
Levels Of Parp1-Immunoreactivity In The Human Brain In Major Depressive Disorder, Aamir Shaikh
Levels Of Parp1-Immunoreactivity In The Human Brain In Major Depressive Disorder, Aamir Shaikh
Undergraduate Honors Theses
MDD is a severe and debilitating disorder that is associated with a growing global economic burden due to reduced workplace productivity along with increased healthcare resource utilization. Furthermore, depression markedly enhances the risk for suicide, mortality that is especially worrisome given that 30% of depressed individuals have an inadequate response to current antidepressants. This inadequacy of antidepressants necessitates the discovery of a better understanding of the pathobiology of MDD. Most current antidepressants work through monoamine neurotransmitters, and their relative efficacy in depression led to the now dated monoamine-deficiency hypothesis. The limited usefulness of antidepressants has led to a reinvigorated search …
