Staying Hydrated: A Comparative Analysis Of Humectants In Human Skin, Ayden Olsen, Rachel Prince, Craig Reeves, Cassie Peterson, Jason Adams

Library/Life Sciences Undergraduate Poster Competition 2022

Humectants are an important class of compounds that attract and retain water within a cell. When mixed with water to create wetting solutions, humectants can prevent desiccation of cadaveric specimens. Recognizing a relative scarcity of comparative studies analyzing the effects of various wetting solutions on post preservation cadaveric maintenance, we utilized wet-dry analysis in order to compare the effects of four common humectants on water retention in human skin tissue. We created a concentration gradient for each humectant to identify the optimal concentrations of each compound for water retention, after which we compared water retention in tissue at the optimal …

New Treatment For Multiple Sclerosis Could Halt Disease Progression Without Weakening Immune System, Carter Helquist, Dario Mizrachi

Library/Life Sciences Undergraduate Poster Competition 2022

• Multiple Sclerosis (MS) is a debilitating neurological and autoimmune disease in which immune cells cause demyelination of axons in nervous tissue.
• Current treatments for the disease are principally aimed at weakening the immune system to therefore weaken the autoimmune attack on the brain. This leaves patients prone to other sicknesses.
• We seek a treatment that prevents the immune cells from entering the central nervous system (CNS) thereby protecting its cells.
• We can prevent immune cells from entering the CNS by strengthening the blood brain barrier through targeting claudin 5 proteins in the tight junctions.
• This new treatment could mean increased …

Comparison Of Free Versus Encapsulated Drugs On 3t3 Differentiation, Simon H. Friedrich, Gabriel Volpe

Undergraduate Research Posters

The scope of this project was to design, synthesize and test targeted nanoparticles containing hydrophobic and hydrophilic drugs that promote browning in adipose tissue. For hydrophilic drugs the use of liposomes and their hydrophilic core is more useful than the PLGA nanoparticles which have hydrophobic cores. The inhibition of the FOXO1 pathway and modulation of autophagy in adipose tissue can promote browning of white adipose tissue, or an energy burning state where excess energy is burned as heat instead of stored in the cell. If successful, these drugs would offer an alternative treatment for obesity where changes to the patient's …

The Effects Of Neuronal Growth Factors On Lps-Activated Schwann Cells, Caitlyn E. Henry, Peyton Kimmel, Angela Asirvatham Ph.D.

Student Research Poster Presentations 2022

Schwann cells (SCs) are the principal support cells of neurons in the peripheral nervous system, that both myelinate axons for the rapid conduction of electrical impulses as well as assist in axonal repair during nerve injury. During nerve injury, SCs secrete tumor necrosis factor alpha (TNF-α)^1,5,6 and other proinflammatory mediators^1,6, attracting macrophages to the site of injury to induce inflammation and clear myelin debris.^1,6 Once the debris is cleared, the neuron stimulates SC proliferation by secreting neuronal mitogens, such as heregulin^3,4, and an unknown factor that activates the cAMP pathway³, an important …

Simulation Of An Inflammatory Model Using Schwann Cells, Caitlyn Henry, Peyton Kimmel, Angela Asirvatham

Student Research Poster Presentations 2022

During peripheral nerve injury, the myelin surrounding the neuronal axons is damaged, initiating an inflammatory response to remove myelin debris. Once myelin debris is cleared, Schwann cells acquire a proliferating phenotype which allows them to grow and divide so that remyelination can occur. The neuron stimulates Schwann cell division by secreting growth factors, like heregulin, and an unknown growth factor that activates the cAMP pathway. Although the role of cAMP in axonal regeneration is well-known, not much has been explored about its function in Schwann cells during nerve injury and inflammation. To simulate an inflammatory environment, the S16 Schwann cell …
