Corticobasal Syndrome With Mixed Pathology In The Absence Of Grn Mutation: A Clinico-Pathological Case Of Ftld-Tdp With Coexisting Alzheimer’S And Lewy Body Pathology, Hugo Zamarron, David Irwin, Jeffery Phillips, Edward Lee, Matthew Tisdall, Corey Mcmillan

Research Colloquium

Background: Corticobasal syndrome (CBS) is a neurodegenerative disorder characterized by often asymmetric fronto-pariteal and extra-pyramidal features that is traditionally associated with tauopathy, but pathological findings are heterogenous, including other forms of frontotemporal lobar degeneration (FTLD) and mixed pathologies of aging. We present clinical, radiographic, and histopathologic features of asymmetry in a unique patient with CBS and underlying FTLD with TDP-43 pathology (FTLD-TDP), co-occurring with other age-related pathologies.

Case Presentation: A 76-year-old man presented with progressive cognitive and motor dysfunction including asymmetric parkinsonism, left-sided dystonia and rigidity, apraxia, visuospatial impairment, and a subtle social disorder including apathy and social withdrawal. The …

A Neurodevelopmental Perspective To Improve Innovation In Preventive Treatment Of Substance Use Disorders, Ismael Perez, John Vandeberg, Mario Gil

Research Symposium

Background: Midbrain dopaminergic neurons have been associated with substance use disorders (Blaess & Ang, 2015). Understanding their neurodevelopment during early stages of life is fundamental for innovating preventive care treatments. The animal model Monodelphis domestica has been proposed as an excellent candidate to study neurodevelopmental changes due to the ease of access to see changes in their embryonic development (Mate et al., 1994). The purpose of our study is to inform how brain cells, including and especially dopaminergic neurons, mature by quantifying their number during early development. Additionally, the study aims to compare different midbrain areas and track neurodevelopmental changes …

Triazole Compounds – Potentials In The Treatment Of Cystic Fibrosis, Maggie Taylor

Undergraduate Research Conference

Cystic Fibrosis (CF) is a genetic disease that affects the respiratory and digestive system and is most common among Caucasians of Northern European origin. CF is caused by mutations in a membrane protein CFTR (Cystic Fibrosis Transmembrane-conductance Regulator). This mutation impairs the membrane protein’s chloride ion channel function. One of the most common CFTR mutations is the DF508 mutation that affects over 70% of CF cases. Our research has shown that the DF508-CFTR mutation can be partially reversed by physical and chemical means [Heda & Marino, BBRC, 271:659-664, 2000]. In cell lines expressing DF508-CFTR, synthetic anion carriers have shown to …

High Energy Blue Light Induces Oxidative Stress And Retinal Cell Apoptosis, Jessica Malinsky

Capstone Showcase

Blue light (BL) is a high energy, short wavelength spanning 400 to 500 nm. Found in technological and environmental forms, BL has been shown to induce photochemical damage of the retina by reactive oxygen species (ROS) production. Excess ROS leads to oxidative stress, which disrupts retinal mitochondrial structure and function. As mitochondria amply occupy photoreceptors, they also contribute to oxidative stress due to their selectively significant absorption of BL at 400 to 500 nm. ROS generation that induces oxidative stress subsequently promotes retinal mitochondrial apoptosis. BL filtering and preventative mechanisms have been suggested to improve or repair BL-induced retinal damage, …

Variations In Antibody Response To Aspergillus Fumigatus Inhalation In Mice, Andrea Wells

Student Academic Conference

Studies have configured immunological responses to Aspergillus fumigatus in mice, leading to advanced understandings. However, the comparisons of the immune responses between juvenile (younger than 6 weeks) male and female C57BL/6J mice after A. fumigatus exposure, remains uninvestigated. In this study, we intranasally inoculated 3 week old male and female mice with Aspergillus fumigatus spores dilution of 2 106spores per 40 l. They were exposed to the allergen once a week for 8 consecutive weeks and euthanized on day 28 post the last inoculation. As compared to our last report, we increased the sample size for each group in this …

Design And Development Of Software With A Graphical User Interface To Display And Convert Multiple Microscopic Histology Images, Sayed Ahmadreza Razian, Majid Jadidi, Alexey Kamenskiy

UNO Student Research and Creative Activity Fair

Histological images are widely used to assess the microscopic anatomy of biological tissues. Recent advancements in image analysis allow the identification of structural features on histological sections that can help advance medical device development, brain and cancer research, drug discovery, vascular mechanobiology, and many other fields. Histological slide scanners create images in SVS and TIFF formats that were designed to archive image blocks and high-resolution textual information. Because these formats were primarily intended for storage, they are often not compatible with conventional image analysis software and require conversion before they can be used in research. We have developed a user-friendly …
