The Wallflower Prototype
No full textThe Wallflower Prototype is based on my novel, “Wallflower.” “Wallflower” follows the story of daring trauma survivor, Robyn. She uncovers a dark truth - demons and she-devils look just like her. Armed with her newfound strength and courage, she takes it upon herself to face the darkness and prove that true power comes from within. This novel stemmed from a thought experiment. I pondered a thought-provoking scenario: What if in a society, people\u27s choices were believed to be influenced by malevolent demons, and the terrible atrocities committed by humanity were the work of these dark forces

Analysis of Terrestrial Deep Subsurface Simulated Environment and Native Microorganisms Interacting with Oxidative Hydrothermal Dissolution Processed Corn Cob
No full textAn increase in atmospheric carbon dioxide (CO2) concentrations has been observed, with values ~40% higher than those seen in the last 800,000 years. This increase in atmospheric CO2 has been linked to anthropogenic emissions due to burning of fossil fuels, and is considered a major driving factor of the contemporary climate change. Development and implementation of carbon dioxide removal (CDR) methods is imperative to the mitigation and reversal of climate change and its effects. Carbon fixing organisms, such as plants, are able to remove CO2 from the atmosphere and store it as biomass. A novel CDR method known as indirect air capture (iDAC) proposes to make use of a technology known as Oxidative Hydrothermal Dissolution (OHD) to break down biomass into low molecular weight water soluble molecules. With the iDAC method, the OHD processed biomass would by injected into a deep subsurface geological reservoir for long term sequestration of the carbon. The deep subsurface is not a sterile environment, but rather its own ecosystem populated with a diverse phylogenetic array of microorganisms. OHD-processed biomass injected into the deep subsurface would certainly come into contact with these communities, and introduce to them new compounds and chemical characteristics. In this study, an OHD-processed corn cob solution was injected into a simulated deep subsurface environment containing deep subsurface microorganisms in order to observe outcomes of interaction and to provide data that can be extrapolated for scale-up and in situ iDAC method studies. The results of this study showed that during the interaction between the OHD-processed corn cob and subsurface native and non-native microorganisms there was a shift in the microbial community but no loss of biodiversity. Additionally, over the course of the study, production of CO2 was observed. Further studies are recommended to amend the OHD-processed corn cob solution by basification to expectedly mitigate the production of CO2
Evolution of iron silicate minerals over geologic time utilizing mineral databases
No full textThere is an implication that minerals have been evolving for the entirety of Earth’s history. Iron silicate minerals are very abundant in Earth’s crust, form in a wide range of pressure, temperature, Eh, pH conditions, and are more resistant to weathering than other iron mineral groups, therefore are expected to be representative of the overall changes that occur through geologic time. Iron is a redox sensitive element, and the valence state of iron in iron silicate minerals can be used to track large-scale geologic events, such as supercontinent formation periods and the Great Oxidation Event. Comparing the average oxidation state of iron through geologic time with atmospheric oxygen abundance reconstructions we can observe a 200-million-year time lag between the increase in average iron oxidation and the increase in O2 in the atmosphere. This time lag is interpreted as iron acting as a sink for molecular oxygen. Iron was being oxidized from Fe2+ to Fe3+ and being deposited in large quantities as the Banded Iron Formations

Interplay of NR3C1 and FOXO1 in somatotrope differentiation
No full textThis study investigates the molecular mechanisms governing pituitary gland development,focusing on the roles of transcription factors NR3C1 and FOXO1 in the differentiation and maturation of somatotropes, responsible for GH production. NR3C1, activated by glucocorticoids, is critical for somatotrope maturation and GH production, while FOXO1 plays a key role in mediating NR3C1’s effects. Disruptions in NR3C1 signaling impair somatotrope development, indicating its importance in maintaining normal pituitary function. Furthermore, FOXO1 is also essential for glucocorticoid-induced somatotrope maturation and GH expression, as demonstrated by in vitro and in vivo models where FOXO1 deficiency results in significantly reduced GH production. Additionally, FOXO1 regulates the heat shock protein Hsp90b1, a chaperone that stabilizes NR3C1, ensuring effective glucocorticoid signaling and proper somatotrope differentiation. This research provides a comprehensive understanding of how NR3C1 and FOXO1 interact to regulate pituitary development, highlighting a broader role of glucocorticoid signaling and its importance in maintaining molecular interactions necessary for somatotrope function
