Identification Of The Role Of Swra In Copper Induced Poly-Gamma-Glutamic Acid Production In Bacillus Subtilis, Maya Addison Jan 2022

Identification Of The Role Of Swra In Copper Induced Poly-Gamma-Glutamic Acid Production In Bacillus Subtilis, Maya Addison

Scripps Senior Theses

Each year over 2.8 million Americans are infected by an antibiotic resistant strain of bacteria with over 35, 000 dying as a result (CDC). The lack of development of new antibiotics has renewed interest in the antimicrobial properties of copper. Gram positive bacterium such as Bacillus subtilis produce poly-gamma-glutamic acid (γ-PGA) to sequester excess copper ions. swrA has shown to be essential for proper activation of the pgs operon by phosphorylated DegU via an unknown mechanism. This study seeks to determine the role of swrA in copper induced gamma-PGA production and if swrA and ppsB are involved in copper resistance. …


A Flora Of Coyote Ridge And Flat, Inyo County, California, Martin Purdy Jan 2022

A Flora Of Coyote Ridge And Flat, Inyo County, California, Martin Purdy

CGU Theses & Dissertations

California’s Sierra Nevada mountain range contains a disproportionate share of the state’s plant diversity and is one of the most floristically diverse regions of its size in the United States. The high Sierra Nevada, in particular, has been identified as an important center of species richness and endemism within California. Anthropogenic climate warming is expected to disproportionately affect mountain ecosystems, and models have predicted serious habitat contraction and extirpation for many alpine plant taxa. A specimen-based inventory of the vascular and non-vascular plants of Coyote Ridge and Flat was conducted to establish baseline data for one such sensitive alpine and …


Parent-Prompted Dysregulation: Do Parents Serve As Cues For Dysregulation In Some Children?, Daniel Lee Jan 2022

Parent-Prompted Dysregulation: Do Parents Serve As Cues For Dysregulation In Some Children?, Daniel Lee

Pitzer Senior Theses

Children occasionally encounter dysregulation when interacting with their parents in relatively neutral or positive scenarios. Given that the cause of dysregulation is usually relational, meaning it is often cued by someone who is seen to have power or control over the person, children could be particularly susceptible to dysregulation in the presence of their parents. However, when examining the existing literature, there appeared to be a lack of research and knowledge concerning this topic, with much of the literature focusing on the effect of child stressors on parental dysregulation. As a result, the term parent-prompted dysregulation was developed to refer …


A Serological Analysis Of Sars-Cov-2 Infection In The Obstetric Population, Sophia Rose Jan 2022

A Serological Analysis Of Sars-Cov-2 Infection In The Obstetric Population, Sophia Rose

CMC Senior Theses

In December 2019, the surfacing and spread of a novel coronavirus, SARS-CoV-2, resulted in the global COVID-19 pandemic. As a viral antigen, SARS-CoV-2 poses a particular threat to the obstetric population due to physiological and immunological changes that women face during pregnancy. While recent studies have found that SARS-CoV-2 may have better clinical outcomes as compared to other betacoronaviruses, adverse pregnancy events such as ICU admission, preeclampsia, and/or preterm birth have been associated with COVID-19. Progress has been made in better understanding the pathophysiology of SARS-CoV-2 in pregnancy, but there is still much to be known about the interaction …


Physician Assisted Dying (Pad): An Investigation Into The Mechanistic Action Of Opioid, Benzodiazepine, And Barbiturate Administration As An Alternative Measure To Forgoing Life Sustaining Treatment And Aggressive Palliation., Jordana Chanel Deighton Jan 2022

Physician Assisted Dying (Pad): An Investigation Into The Mechanistic Action Of Opioid, Benzodiazepine, And Barbiturate Administration As An Alternative Measure To Forgoing Life Sustaining Treatment And Aggressive Palliation., Jordana Chanel Deighton

CMC Senior Theses

Whilst modern medicine has increased longevity, the rise in life expectancy has brought about new struggles, namely that of aging and age related disease. Thus, humanity has been presented with a new problem: at what point is death preferable to aggressive life-prolonging treatment in the face of inevitable death? And if so, what right do individuals have to control the circumstances of their death? In the West, traditionally, individuals who seek to end their own lives in the face of terminal illness opt for forgoing artificial hydration and nutrition. Driven by an increase in desire for autonomous dignified death, a …


Effects Of Drought On Habitat Quality For Native Bees In Residential Gardens Of Claremont, Ca, Max Proctor Jan 2022

Effects Of Drought On Habitat Quality For Native Bees In Residential Gardens Of Claremont, Ca, Max Proctor

CMC Senior Theses

Over 1,500 of the 4000 bee species found in North America inhabit California. Native bees are declining however, largely due to climate change and agricultural intensification. Previous research shows that cities can sustain diverse bee communities, due to the diversity of ornamental flowers. Urban green space represents an opportunity for native bee conservation. Residential gardens provide lots of green space and are urban pollinator hotspots. Managing yards for increased floral resources and nesting habitat can benefit native bee communities. Turfgrass provides few floral or nesting resources and negatively correlates with bee diversity. The 2011-2017 California drought caused many homeowners to …


Not Coming Home: The Flaws In Skilled Nursing Facilities And Their Contribution To Cyclical Hospitalizations Of Post-Acute Patients, Kate Eisenbraun Jan 2022

Not Coming Home: The Flaws In Skilled Nursing Facilities And Their Contribution To Cyclical Hospitalizations Of Post-Acute Patients, Kate Eisenbraun

Pitzer Senior Theses

This literature review will discuss the experience of patients within the US healthcare system, focusing on skilled nursing facilities (SNFs) and their contribution to cyclical hospitalizations. SNFs differ from nursing homes and other long-term care facilities by providing short-term, post-operational rehabilitation at a cost lower than what is offered at hospitals. Despite their critical role, SNFs often face fundamental issues, such as understaffing, underfunding, and staff burn-out, which result in lower quality patient care. This thesis argues that the issues faced by SNFs are a result of inconsistencies with state and federal staffing regulations, as well as inadequate insurance reimbursements. …
