A Persuasive Case Against Government Authority In End-Of-Life Decisions For Vegetative Patients, Helen Gizachew Apr 2024

A Persuasive Case Against Government Authority In End-Of-Life Decisions For Vegetative Patients, Helen Gizachew

Helm's School of Government Conference - American Revival: Citizenship & Virtue

The debate over whether the government should have jurisdiction to withdraw life support from people in a vegetative state is heating up, producing a persuasive case emphasizing the need to protect human liberty and oppose government overreach in matters of life and death. The key tenet of this argument is individual autonomy, which stresses a person's freedom to make decisions about their own life and body. Giving the government the authority to decide the fate of people in vegetative states violates this basic right, setting a dangerous precedent that undermines personal liberty and self-determination. Entrusting such decisions to a bureaucratic …

Investigating Vital Neutrophil Extracellular Trap Pathogen Response In Neutropenic Individuals, Ryan Illig Apr 2024

Investigating Vital Neutrophil Extracellular Trap Pathogen Response In Neutropenic Individuals, Ryan Illig

Thinking Matters Symposium

Neutrophils, also called polymorphonuclear leukocytes (PMNs), constitute the majority of innate immune cells. These cells possess a complex arsenal of functions that allow them to detect and eliminate a broad spectrum of pathogens. Neutropenia is characterized by decreased levels of neutrophils in the bloodstream, typically falling below the normal range. Moderate to severe neutropenia can increase the risk of pathogenic infections and without treatment can be life-threatening. Although the concentration of neutrophils in neutropenic individuals is decreased, upon activation, neutrophils still release neutrophil extracellular traps (NETs). NETs are pivotal in combating a spectrum of pathogens through their non-selective nature. Overreactive …

Targeting Tgf-Β During Epithelial-To-Mesenchymal Progression As An Effective Therapy Against Colorectal Cancer, Joyce Fan

Undergraduate Research

Colorectal cancer is one of the most common cancers worldwide. Understanding the mechanisms of colorectal cancer progression is crucial for the development of effective therapeutics. Epithelial-to-mesenchymal transition is a hallmark feature of cancer and is defined as the loss of epithelial cell features, such as apical-basal polarity and high expression of cell adhesion molecules, and the development of mesenchymal features, such as lack of polarity and increased cell mobility. Epithelial-to-mesenchymal is essential for cell migration, proliferation, and tumor growth. Both the TGF-β and SMAD pathway are associated with colorectal cancer progression. TGF-β is crucial to the cellular mechanism of cell …

School of Medicine Publications and Presentations

Although previous studies have examined the signaling pathway involved in melanogenesis through which ultraviolet (UV) or α-melanocyte-stimulating hormones (α-MSH) stimuli act as key inducers to produce melanin at the stratum basal layer of the epidermis, the signaling pathway regulating melanogenesis is still controversial. This study reports that α-MSH, not UVA and UVB, acted as a major stimulus of melanogenesis in B16F10 melanoma cells. Signaling pathway analysis using gene knockdown technology and chemical inhibitors, the mitogen-activated protein kinase kinase (MEK)/extracellular signal-regulated kinase (ERK)/p90 ribosomal S6 kinase 2 (RSK2) played an important role in melanogenesis. Unexpectedly, LY294002, a PI3K inhibitor, increased melanogenesis …
