The Role Of Oral Microbiota In Periodontitis And Alzheimer's Disease, Noah Al-Hassan, Taha Al Hassan, Juan C. Lopez-Alvarenga, Maria Quinones, Seratna Guadarrama

Research Symposium

Background: Periodontal disease (PD), affecting 20-50% of the global population is marked by biofilm-induced inflammation in oral tissues. Chronic PD results in systemic complications such as heart disease, stroke, and Alzheimer's. The red complex microbes, Porphyromonas gingivalis and Treponema denticola, play a pivotal role, penetrating the blood-brain barrier and contributing to neurodegeneration. Alzheimer's disease (AD), an irreversible neurodegenerative disorder, is linked to abnormal protein cleavage and potentially involves microbiologic components, including gram-positive cocci. Research suggests the presence of bacteria such as Porphyromonas, Actinomyces, and Treponema in autopsied AD brains. Investigating the microbiologic connection between PD and AD is crucial, considering …

Investigating Interrater-Reliability In Assessing Social Behavior Of Monodelphis Domestica, Bianca A. Camacho, Johanna Perez, Jatziry L. Escobedo, John L. Vandeberg, Mario Gil

Research Symposium

Background: Reliable, consistent, and objective data is a goal all studies aim to achieve, but many struggle to obtain when subjective biases between researchers can occur. Inter-rater reliability (IRR) is a statistical measure used to quantify the degree of agreement between researchers qualitatively scoring the same phenomenon. The primary goal of this study is to enhance the methodology used to achieve optimal IRR. Using an established ethogram, our team of researchers scored the social behavior of the adult gray short-tailed opossum (Monodelphis domestica) to propose an effective method for achieving high IRR that can contribute to future …


Gamma-Aminobutyric Acid (Gaba) Neurons And Perineuronal Nets (Pnn) In The Monodelphis Domestica And Relevance To Psychiatric Disorders, Jatziry Z. Luna Escobedo, Mariela Garcia, John L. Vandeberg, Mario Gil Mar 2024

Gamma-Aminobutyric Acid (Gaba) Neurons And Perineuronal Nets (Pnn) In The Monodelphis Domestica And Relevance To Psychiatric Disorders, Jatziry Z. Luna Escobedo, Mariela Garcia, John L. Vandeberg, Mario Gil

Research Symposium

Background/ Purpose: Gamma-aminobutyric acid (GABA) is an amino acid that serves as the central nervous system’s (CNS) main inhibitory neurotransmitter. By inhibiting nerve transmission, it works to lower neuronal excitability. Altered GABA levels have been associated with a variety of psychiatric disorders, for example Epilepsies, Parkinson’s Disease, and Schizophrenia. Perineuronal nets (PNN) are extracellular molecules that are released by neurons and glial cells that modulate many neuronal and glial functions by encapsulating the inhibitory cells and neurites. Altered PNN levels serve as a potential trigger to synaptic imbalance. The purpose of this study is to quantify and analyze the presence, …
