Comprehensive Analysis Of The Retinal Cell Contributions To The Human Erg, Christopher W. Tyler May 2023

Comprehensive Analysis Of The Retinal Cell Contributions To The Human Erg, Christopher W. Tyler

MODVIS Workshop

Purpose. Standard electroretinogram (ERG) protocols are largely designed to isolate the responses of the rod and cone retinal pathways, including the use of adapting backgrounds to suppress unwanted off-pathway responses. Here, we record spectral ERGs in the low-to-high mesopic sensitivity range in the absence of any adapting background in order to assess interactions between the pathways.

Methods. We have developed a comprehensive neuroanalytic model of the component structure of the ERG driven by knowledge of the underlying retinal physiology, to enhance its power as a critical diagnostic tool for a broad range of both retinal and systemic dysfunctions. The ERG …

Get It From The Source: Identifying Library Resources And Software Used In Faculty Research, Karen S. Alcorn, Erin E. Wentz, Gregory A. Martin, Shanti C. Freundlich, Joanne A. Doucette

Charleston Library Conference

Libraries and Information Technology departments aim to support the educational and research needs of students, researchers, and faculty members. Close matches between the resources those departments provide and the resources the institution’s community members actually use highlight the value of the departments, demonstrate fiscally responsibility, and show attentiveness to the community’s needs. Traditionally, libraries rely on usage statistics to guide collection development decisions, but usage statistics can only imply value. Identifying a resource by name in a publication demonstrates the value of that resource more clearly. This pilot project examined the full-text of articles published in 2016-2017 by faculty members …

Modeling Visual Enumeration Using Cumulative Link Regression., Anthony D. Cate Ph.D. May 2019

Modeling Visual Enumeration Using Cumulative Link Regression., Anthony D. Cate Ph.D.

MODVIS Workshop

Based on three core assumptions about mental representations of number, this model of visual enumeration specifies analysis methods that can identify when observers rely on different processes to estimate the numerosity of a visual display. Specifically, the model provides a clear criterion for identifying domains of numerosity that correspond to different perceptual or cognitive processes that have been described in numeracy literature, e.g. subitizing. The model predicts how the requirement to give integer responses in enumeration tasks can produce spurious discontinuities in accuracy measures that can be misidentified as evidence for a subitizing process. It is proposed that cumulative link …

Reimagining Print Materials In A Health Science Context: Creating And Marketing A Wellness Collection, Margaret Ansell, Ariel Pomputius

Charleston Library Conference

In the healthcare field in which out-of-date information can harm patients, the currency and immediacy of digital collections is highly valued. As a result, many health science libraries have deselected much of their print collections (Haapanen, Kultamaa, Ovaska, & Salmi, 2015; Lingle & Robinson, 2009; Tobia & Hunnicutt, 2008; Xiaoli & Kopper, 2005). However, print materials continue to be valued by health science library users for a variety of purposes (Houghton, 2017; Watson, 2016). This paper describes how one academic health science center library found a role for print materials in the context of a wellness initiative, which (1) gave …

Mass Spectrometry Image Creator (Msic): Ion Mobility / Mass Spectrometry Imaging Workflow In Python, Stephen Creger, Julia Laskin, Daniela Mesa Sanchez Aug 2018

Mass Spectrometry Image Creator (Msic): Ion Mobility / Mass Spectrometry Imaging Workflow In Python, Stephen Creger, Julia Laskin, Daniela Mesa Sanchez

The Summer Undergraduate Research Fellowship (SURF) Symposium

Mass spectrometry (MS) is a powerful characterization technique that enables identification of compounds in complex mixtures. Acquiring mass spectra in a spatially-resolved manner (i.e. over a grid), allows the data to be used to generate images that show the spatial distribution and relative intensities of every compound in a sample. These images can be used to monitor and identify biomarkers, explore the metabolism of compounds within tissues, and much more. However, the limitations of mass spectrometry can result in ambiguous compound identifications. Another characterization tool, ion mobility spectrometry (IM) can be integrated into existing MS routines to address this problem; …

Polyrotaxane Variants And Their Effects On The Cholesterol Efflux In Patients Suffering From Niemann Pick Type C, Sydney Smith, Zach Struzik, David Thompson

The Summer Undergraduate Research Fellowship (SURF) Symposium

Niemann Pick type C disease (NPC) is a rare lysosomal storage disorder characterized by a progressive accumulation of cholesterol in the late endosomal/lysosomes compartment leading to cellular dysfunction and organ failure. Symptoms include ataxia, dysarthria, cognitive dysfunction, and seizures. Although average life expectancy is below 20, there are no FDA approved treatment available making it a serious unmet medical need. Clinical trials with 2-hydroxypropyl-beta-cyclodextrin (HP-beta-CD) has shown promise in cholesterol normalization within NPC cells. However, HP-beta-CD treatment has been shown to cause ototoxicity in NPC patients at high dosages. Supramolecular complexes known as polyrotaxanes have been synthesized in hopes of …


Targeting Pro-Inflammatory Function Of Microglia Using Small Molecules To Combat Neurodegeneration, Gabrielle C. Williams, Priya Prakash, Gaurav Chopra Aug 2018

Targeting Pro-Inflammatory Function Of Microglia Using Small Molecules To Combat Neurodegeneration, Gabrielle C. Williams, Priya Prakash, Gaurav Chopra

The Summer Undergraduate Research Fellowship (SURF) Symposium

Microglia are the brain’s resident immune cells that are responsible for maintaining homeostasis in healthy conditions. During injury or infection, resting microglia get activated and produce pro-inflammatory cytokines such as IL-1b, IL-1a, IL-6, etc. along with reactive oxygen species like nitric oxide (NO) to combat neuroinflammatory diseases such as Alzheimer’s disease (AD). Inflammation is characterized by the activation of resident-immune cells in the brain called microglia that respond to the eat-me signals released by the toxic amyloid beta peptides as well as the dying neurons in the microenvironment. Recent studies have shown that activated microglia induce neuronal death by secreting …

Targeting Neuropeptides To Bone Fractures For Accelerated Healing, Nicholas A. Young, Jeffery J. Nielsen, Philip S. Low Aug 2018

Targeting Neuropeptides To Bone Fractures For Accelerated Healing, Nicholas A. Young, Jeffery J. Nielsen, Philip S. Low

The Summer Undergraduate Research Fellowship (SURF) Symposium

In patients over the age of 65 especially, bone fractures represent a significant disease burden. Non-invasive drug therapies are not available for bone fractures which represents a problem for this population. Vasoactive intestinal peptide (VIP) and Pituitary Adenylate Cyclase-Activating Polypeptide (PACAP), two neuromodulator peptides in the glucagon superfamily, have demonstrated positive regulation of osteoblast proliferation and activity. Using acidic oligopeptides, we have developed ligands that target to and accumulate at fracture sites. These targeting ligands can be synthesized in sequence with bone anabolic peptides to minimize off target effects and increase potency at the fracture site to create safer and …
