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 …

The Role Of Age And Biological Sex On Short-Term Memory In The Syrian Hamster (Mesocricetus Auratus), Laura E. Garcia, Mario Gil

Research Symposium

Background: Aging plays an important role in cognitive function, memory, and mental health. As we age, some cognitive functions become weaker. Aging is also a critical risk factor for dementia and Alzheimer’s Disease. With recent advances seen in public health, humans are living longer years. This makes it a challenge to make those added years healthy. For this reason, it is important to continue studying its effects by using, the Syrian hamster, as a model. The purpose of the study is to identify other factors that might also have a role in short-term memory, besides aging.

Methods: All behavioral …

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

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, …

The Impact Of Biological Sex On Motor Function And Responses To Novel Environments In The Gray Short-Tailed Opossum (Monodelphis Domestica), Esperanza I. Alaniz, Ismael Perez, Sasawan Heingraj, Katelynn Renteria, Cristian M. Botello, Joseph C. Cantu, John L. Vandeberg, Mario Gil

Research Symposium

Background: Understanding the different stress reactions in different environments can help us understand stress factors. Studying animal behavior is important for translational research for mental health improvement.

Previous literature has shown that stress is a risk factor for higher cancer incidence and poorer cancer survival. (Klejbor & Turlejski., 2012), as well as mental health outcomes. Understanding of how stress is related to cancer can help improve therapeutic outcomes as preventive measures (Glaser et al., 1987).

Methods: Using the Rota Rod apparatus, 12 animals (3 males, 9 females) were tested at 36 rpm for a maximum of 400 seconds (Madroñal et …

Mind, Body And Race: A Look Into How Implicit Biases Influence The Perception Of Emotion, Faiza Ahmad, Adam Anderson, James Dalton Rounds, Christina Chick, Alize Hill

Research Symposium

Background: Most research examining the effects of implicit race-based biases in emotion perception has focused on the perception of Black faces as being angry. Limited work has been done examining the perception of “approach” emotions such as fear. Furthermore, most studies have predominantly used White subjects. Our study examined the role of implicit racial biases in shaping the perception of both anger and fear in White, Black and Asian participants.

Methods: 78 participants completed a Go/NoGo task in which they were asked to categorize different race faces as portraying either anger or fear. Participants would be asked to press the …

From Bench To Bedside: Bridging The Gap Between Animal Behavior Research And The Study Of Human Personality And Psychopathology, William Reckley, Mario Gil

Research Symposium

Background: Most psychopathology focuses on the current mental picture of an individual with some including relations to the past experience. One problem with the biomedical studies of psychopathologies is the difficulty in using animals to describe and model these mental states in humans. This difficult task has been confounded by the inability to classify animals in a way that will provide general models that will allow better translation to hypotheses in humans. Therefore, the present investigation explores statistical/research strategies to organize variables using lab animals to facilitate the translation of this information to humans.

Methods: Factor analysis/PCA was used to …

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 …

Residential Treatment Of Substance Use Disorder And Related Comorbidities In Older Adults, Dale J. Dyben

Research Symposium

Purpose: Substance Use Disorders (SUD) are a leading contributor to health problems and premature mortality in the United States. Stigma and misconceptions about persons with SUD contribute to negative outcomes. The misconception that older adults do not suffer from severe SUD has contributed to a paucity of treatment options that meet the unique needs this population.

Description: The Center for Older Adult Recovery (COAR) at Hanley Center in West Palm Beach, Florida provides a model for residential treatment of older 65 and older with severe SUD and related medical and mental health comorbidities. Older adults who meet DSM-V diagnostic …

The Impact Of Social Isolation On The Neural Pathways Of Dopamine Neurons In The Ventral Tegmental Area (Vta) And The Nucelus Accumbens (Nac): Implications For The Treatment Of Depression, Anxiety, And Drug Addiction., Cristian M. Botello, Sasawan Heingraj, John L. Vandeberg, Mario Gil

Research Symposium

As the literature on the Monodelphis domestica continues to grow, it is important to contribute to the knowledge base regarding neural pathways and their role in social behavior in this species. Previous studies have provided evidence that increased activity in ventral tegmental area (VTA) dopamine neurons were associated with more social activity in mice. It is also known that in traditional rodent models, the Nucleus Accumbens (NAcc) is implicated in interaction reward processes like motivation; however, more research is needed to elucidate the role of the NAcc in social behavior of the M. domestica. The present study was designed …
