Identifying Potential Antibiotic Uptake Mechanisms Of Streptococcus Pneumoniae, Yuri Laguna Terai
Identifying Potential Antibiotic Uptake Mechanisms Of Streptococcus Pneumoniae, Yuri Laguna Terai
Theses and Dissertations
Streptococcus pneumoniae (pneumococcus) is a commensal gram-positive colonizer of the human nasopharynx capable of causing diseases including otitis media, pneumonia, bacteremia, and meningitis. Although it is often a harmless colonizer, there is a high rate of mortality and morbidity among the immunocompromised, elderly, and young children. While these infections can often be treated with antibiotics, resistance to numerous antibiotics is increasing. Antibiotic resistance is a well-studied dilemma; however, little information is known of how bacteria take up certain antibiotics. Because most antibiotics cannot diffuse freely across the bacterial cell wall, we hypothesize that metabolite transport proteins participate in the uptake …

Collectors Versus Non-Collectors With Hoarding Symptoms, Caitlyn A. Nix
Collectors Versus Non-Collectors With Hoarding Symptoms, Caitlyn A. Nix
Theses and Dissertations
Research assessing the diagnostic criteria for hoarding disorder has firmly differentiated hoarding disorder from normative collecting. However, there has been no examination of non-normative collecting – that is, collectors that experience elevated hoarding symptoms. The current study utilized an online survey to explore differences between self-identified collectors (n = 140) and non-collectors (n = 169) in externalized hoarding symptoms, saving cognitions, and psychosocial functioning. Collectors reported higher general self-efficacy and higher need for control of items than non-collectors. Hoarding symptoms were not significantly different between collectors and non-collectors. These results suggest that identifying as a collector does not significantly change …
