Cerebrovascular reactivity (CVR), which measures the ability of cerebral blood vessels to dilate or constrict in response to vasoactive stimuli such as CO2 inhalation, is an important index of the brain's vascular health. Quantification of CVR using BOLD MRI with hypercapnia challenge has shown great promises in research and clinical studies. However, in order for it to be used as a potential imaging biomarker in large-scale and multi-site studies, the reliability of CO2-CVR quantification across different MRI acquisition platforms and researchers/raters must be examined. The goal of this report from the MarkVCID small vessel disease biomarkers consortium is to evaluate …

Contribution Of Retinal Ganglion Cells To Brown-Norway Rat Spatiotemporal Visual Perception And The Electroretinogram, Nicholas P. Johnson

USF Tampa Graduate Theses and Dissertations

Retinal Ganglion Cells (RGCs) are the sole cells through which visual information is transmitted from the eye to the brain. As such, RGC dysfunction has a dramatic effect on vision and perception. Retinal neurodegenerative diseases, such as glaucoma, are one of the leading causes of blindness worldwide. The study of these diseases requires well-characterized models in order to swiftly and effectively develop diagnostic tools and therapeutics. This dissertation aims to characterize specific properties of the visual system of the Brown-Norway rat. First, visual processing was evaluated in awake, freely moving rats. Contrast sensitivities of Brown-Norway rats were characterized by discrimination-driven …

Fibroblast Growth Factor 19 Increases The Excitability Of Pre-Motor Glutamatergic Dorsal Vagal Complex Neurons From Hyperglycemic Mice, Jordan B. Wean, Bret N. Smith

Physiology Faculty Publications

Intracerebroventricular administration of the protein hormone fibroblast growth factor 19 (FGF19) to the hindbrain produces potent antidiabetic effects in hyperglycemic mice that are likely mediated through a vagal parasympathetic mechanism. FGF19 increases the synaptic excitability of parasympathetic motor neurons in the dorsal motor nucleus of the vagus (DMV) from hyperglycemic, but not normoglycemic, mice but the source of this synaptic input is unknown. Neurons in the area postrema (AP) and nucleus tractus solitarius (NTS) express high levels of FGF receptors and exert glutamatergic control over the DMV. This study tested the hypothesis that FGF19 increases glutamate release in the DMV …

Musical Instrument Familiarity Affects Statistical Learning Of Tone Sequences., Stephen C Van Hedger, Ingrid Johnsrude, Laura J Batterink

Brain and Mind Institute Researchers' Publications

Most listeners have an implicit understanding of the rules that govern how music unfolds over time. This knowledge is acquired in part through statistical learning, a robust learning mechanism that allows individuals to extract regularities from the environment. However, it is presently unclear how this prior musical knowledge might facilitate or interfere with the learning of novel tone sequences that do not conform to familiar musical rules. In the present experiment, participants listened to novel, statistically structured tone sequences composed of pitch intervals not typically found in Western music. Between participants, the tone sequences either had the timbre of artificial, …

Ethanol And Opioids Do Not Act Synergistically To Depress Excitation In Carotid Body Type I Cells, Ryan J. Rakoczy, Kajal Kamra, Yoon-Jae Yi, Christopher N. Wyatt

Neuroscience, Cell Biology & Physiology Faculty Publications

The combination of opioids and ethanol can synergistically depress breathing and the acute ventilatory response to hypoxia. Multiple studies have shown that the underlying mechanisms for this may involve calcium channel inhibition in central neurons. But we have previously identified opioid receptors in the carotid bodies and shown that their activation inhibits calcium influx into the chemosensitive cells. Given that the carotid bodies contribute to the drive to breathe and underpin the acute hypoxic ventilatory response, we hypothesized that ethanol and opioids may act synergistically in these peripheral sensory organs to further inhibit calcium influx and therefore inhibit ventilation.

Brain and Mind Institute Researchers' Publications

Background: The COVID-19 pandemic has increased psychological stress among adolescents, and the relation between perceived stress (PS) and psychotic-like experiences (PLEs) has been well-established. However, little is known about the role of family functioning (FF) in this relation, especially when adolescents experienced the extended lockdown period with family members. Methods: A total of 4807 adolescents completed this retrospective paper-and-pencil survey after school reopening between May 14th and June 6th, 2020 in Hunan Province, China. We measured PS with the Perceived stress scale (PSS-10), PLEs with the eight positive items from Community Assessment of Psychic Experiences (CAPE-8), and FF with the …

Modulatory Actions Of The Glycine Receptor Β Subunit On The Positive Allosteric Modulation Of Ethanol In Α2 Containing Receptors, Braulio Muñoz, Trinidad Mariqueo, Pablo Murath, Christian Peters, Gonzalo E. Yevenes, Gustavo Moraga-Cid, Robert W. Peoples, Luis G. Aguayo

Biomedical Sciences Faculty Research and Publications

Alpha1-containing glycine receptors (GlyRs) are major mediators of synaptic inhibition in the spinal cord and brain stem. Recent studies reported the presence of α2-containing GlyRs in other brain regions, such as nucleus accumbens and cerebral cortex. GlyR activation decreases neuronal excitability associated with sensorial information, motor control, and respiratory functions; all of which are significantly altered during ethanol intoxication. We evaluated the role of β GlyR subunits and of two basic amino acid residues, K389 and R390, located in the large intracellular loop (IL) of the α2 GlyR subunit, which are important for binding and functional modulation by Gβγ, the …

Ptsd As An Endothelial Disease: Insights From Covid-19, Adonis Sfera, Carolina Osorio, Leah Rahman, Carlos M. Zapata Martín Del Campo, Jose Campo Maldonado, Nyla Jafri, Michael Cummings, Steve Maurer, Zisis Kozlakidis

School of Medicine Publications and Presentations

SARS-CoV-2 virus, the etiologic agent of COVID-19, has affected almost every aspect of human life, precipitating stress-related pathology in vulnerable individuals. As the prevalence rate of posttraumatic stress disorder in pandemic survivors exceeds that of the general and special populations, the virus may predispose to this disorder by directly interfering with the stress-processing pathways. The SARS-CoV-2 interactome has identified several antigens that may disrupt the blood-brain-barrier by inducing premature senescence in many cell types, including the cerebral endothelial cells. This enables the stress molecules, including angiotensin II, endothelin-1 and plasminogen activator inhibitor 1, to aberrantly activate the amygdala, hippocampus, and …

Pairwise Correlation Analysis Of The Alzheimer’S Disease Neuroimaging Initiative (Adni) Dataset Reveals Significant Feature Correlation, Erik D. Huckvale, Matthew W. Hodgman, Brianna B. Greenwood, Devorah O. Stucki, Katrisa M. Ward, Mark T. W. Ebbert, John S. K. Kauwe, The Alzheimer’S Disease Neuroimaging Initiative, The Alzheimer’S Disease Metabolomics Consortium, Justin B. Miller

Sanders-Brown Center on Aging Faculty Publications

The Alzheimer’s Disease Neuroimaging Initiative (ADNI) contains extensive patient measurements (e.g., magnetic resonance imaging [MRI], biometrics, RNA expression, etc.) from Alzheimer’s disease (AD) cases and controls that have recently been used by machine learning algorithms to evaluate AD onset and progression. While using a variety of biomarkers is essential to AD research, highly correlated input features can significantly decrease machine learning model generalizability and performance. Additionally, redundant features unnecessarily increase computational time and resources necessary to train predictive models. Therefore, we used 49,288 biomarkers and 793,600 extracted MRI features to assess feature correlation within the ADNI dataset to determine the …

Genetic Targeting Of Adult Renshaw Cells Using A Calbindin 1 Destabilized Cre Allele For Intersection With Parvalbumin Or Engrailed1, Alicia R. Lane, Indeara C. Cogdell, Thomas M. Jessell, Jay B. Bikoff, Francisco J. Alvarez

Neuroscience, Cell Biology & Physiology Faculty Publications

Renshaw cells (RCs) are one of the most studied spinal interneurons; however, their roles in motor control remain enigmatic in part due to the lack of experimental models to interfere with RC function, specifically in adults. To overcome this limitation, we leveraged the distinct temporal regulation of Calbindin (Calb1) expression in RCs to create genetic models for timed RC manipulation. We used a Calb1 allele expressing a destabilized Cre (dgCre) theoretically active only upon trimethoprim (TMP) administration. TMP timing and dose influenced RC targeting efficiency, which was highest within the first three postnatal weeks, but specificity was low with …

Effects Of The Tailored Activity Program (Tap) On Dementia-Related Symptoms, Health Events And Caregiver Wellbeing: A Randomized Controlled Trial, Laura N Gitlin, Katherine Marx, Catherine V. Piersol, Nancy A Hodgson, Jin Huang, David L Roth, Constantine Lyketsos

Department of Occupational Therapy Faculty Papers

BACKGROUND: People living with dementia (PLWD) and caregivers are adversely impacted by lack of meaningful activity leading to worse symptoms and impaired quality-of-life. There is a critical need to develop effective and well-tolerated treatments that mitigate clinical symptoms, engage PLWD and support caregiver wellbeing. We tested whether, compared to attention control, the Tailored Activity Program (TAP) reduced clinical symptoms and health-related events, and improved caregiver wellbeing, and if TAP activities were well-tolerated.

METHODS: We conducted a single-blind randomized controlled trial among 250 dyads recruited from Baltimore-Washington DC (2012-2016) with a dementia diagnosis and clinically significant agitation/aggression. Dyads were randomized to …

Validation Of Arterial Spin Labeling For Longitudinal Monitoring And Differential Diagnosis Of Frontotemporal Dementia, Tracy Ssali

Electronic Thesis and Dissertation Repository

Frontotemporal dementia (FTD) is a devastating neurodegenerative disease characterized by a rapid decline in behavioural, language, and motor abilities. Advances in the understanding of FTD genetics and pathophysiology, and the subsequent development of novel disease modifying treatments have highlighted the need for tools to assess their efficacy. While structural magnetic resonance imaging (MRI) and functional imaging with ¹⁸F-flurodeoxyglucose (FDG) positron emission tomography (PET) are used for clinical diagnosis, structural changes are subtle at the early stages and PET imaging is expensive and access limited. Given the coupling of cerebral blood flow (CBF) to energy metabolism, an attractive alternative is …

Investigating The Role Of Adipor1 In Pro-Homeostatic Fatty Acid Metabolism Pathways, Eric Prestenburg, Alise Aucoin, Marie-Audrey Kautzmann-Guerin, Bokkyoo Jun, William Gordon, Nicolas Bazan

Medical Student Research Poster Symposium

Docosahexaenoic acid (DHA, 22:6) is a substrate widely accepted as necessary for synthesizing very-long-chain polyunsaturated fatty acids (VLC-PUFAs), a class of lipids found in high concentrations in the retina. VLC-PUFAs are formed from 28:6 derived in the omega-3 fatty acid pathway involving eicosapentaenoic acid (EPA, 20:5) and docosahexaenoic acid (DHA, 22:6) by a series of reactions catalyzed by the elongase ELOVL4 within the inner segments of the photoreceptor cells (PRCs). VLC-PUFAs are precursors to elovanoids (ELVs), which have been indicated to maintain homeostasis in the retina in response to inflammation and uncompensated oxidative stress (UOS). During these conditions, elovanoids are …

Investigating Neuroprotective Efficacy Of Lipid Mediators Neuroprotectin D1 (Npd1)And Resolvin D1 (Rvd1) On Behavioral Outcomes And Ischemic Penumbra, Kierany B. Shelvin, Madigan M. Reid, Larissa Khourtorova, Jeff Ji, William Lewis, Pranab Mukherjee, Ludmila Belayev, Nicolas G. Bazan

Medical Student Research Poster Symposium

Background: In the United States, stroke is the sixth leading cause of death, and a major cause of long-term disability. Ischemic stroke elicits a cascade of immune and neuroinflammatory responses that form an ischemic core and surrounding area (penumbra) which can be salvaged upon reperfusion within a limited period of time. Reperfusion signals the release of an essential omega-3 fatty acid, Docosahexaenoic acid (DHA) from injured neuronal cell membranes. DHA is converted into its derivatives, Neuroprotectin D1 (NPD1) via 15- lypoxygenase and Resolvin D1 (RvD1) via 15- and 5-lypoxygenase. These docosanoid lipid mediators have been shown to improve neurologic outcomes …

Neuroscience, Cell Biology & Physiology Faculty Publications

Non-steroidal anti-inflammatory drugs (NSAIDs) are used for relieving pain and inflammation accompanying numerous disease states. The primary therapeutic mechanism of these widely used drugs is the inhibition of cyclooxygenase 1 and 2 (COX1, 2) enzymes that catalyze the conversion of arachidonic acid into prostaglandins. At higher doses, NSAIDs are used for prevention of certain types of cancer and as experimental treatments for Alzheimer’s disease. In the immune system, various NSAIDs have been reported to influence neutrophil function and lymphocyte proliferation, and affect ion channels and cellular calcium homeostasis. Transient receptor potential melastatin 7 (TRPM7) cation channels are highly expressed in …

Journal of Mind and Medical Sciences

Undoubtedly, the outbreak of COVID-19 still represents an overanxious event for both society and population. The fear of getting infected is ubiquitous in the time of the pandemic. The population presented worrying thoughts related to the fact that the health care system was not able to provide enough services during the COVID-19 pandemic. The number of the hospital beds and ventilators was insufficient in order to ensure enough care, considering the increased number of COVID-19 cases that were admitted to the hospitals. Furthermore, people were fearful about the possibility of the global economy becoming decimated. The fright and also the …

Enhancing Mask Activity In Dopaminergic Neurons Extends Lifespan In Flies, Xiaolin Tian

School of Medicine Faculty Publications

Dopaminergic neurons (DANs) are essential modulators for brain functions involving memory formation, reward processing, and decision-making. Here I demonstrate a novel and important function of the DANs in regulating aging and longevity. Overexpressing the putative scaffolding protein Mask in two small groups of DANs in flies can significantly extend the lifespan in flies and sustain adult locomotor and fecundity at old ages. This Mask-induced beneficial effect requires dopaminergic transmission but cannot be recapitulated by elevating dopamine production alone in the DANs. Independent activation of Gαs in the same two groups of DANs via the drug-inducible DREADD system also extends fly …

A Comparison Of Calcium Aggregation And Ultracentrifugation Methods For The Preparation Of Rat Brain Microsomes For Drug Metabolism Studies, Barent N. Dubois, Farideh Amirrad, Reza Mehvar

Pharmacy Faculty Articles and Research

Preparation of brain microsomes by the calcium chloride aggregation method has been suggested as an alternative to the ultracentrifugation method. However, the effects of the calcium chloride concentration on the quality of the microsomal fractions are not known. Brain microsomes were prepared from the adult rat brains using the high-speed ultracentrifugation and low-speed calcium chloride (10–100 mM) aggregation methods (n = 5–6 per group). The microsomal protein yield (spectrometry), the cytochrome P450 reductase (CPR) activity (spectrometry), and the monooxygenase activities (UPLC-MS/MS) of CYP2D and CYP2E1 were determined in the obtained fractions. Increasing the concentrations of calcium chloride progressively increased …

The Ephb2 Receptor Uses Homotypic, Head-To-Tail Interactions Within Its Ectodomain As An Autoinhibitory Control Mechanism, Yan Xu, Dorothea Robev, Nayanendu Saha, Bingcheng Wang, Matthew B. Dalva, Kai Xu, Juha P. Himanen, Dimitar B. Nikolov

Department of Neuroscience Faculty Papers

The Eph receptor tyrosine kinases and their ephrin ligands direct axon pathfinding and neuronal cell migration, as well as mediate many other cell–cell communication events. Their dysfunctional signaling has been shown to lead to various diseases, including cancer. The Ephs and ephrins both localize to the plasma membrane and, upon cell–cell contact, form extensive signaling assemblies at the contact sites. The Ephs and the ephrins are divided into A and B subclasses based on their sequence conservation and affinities for each other. The molecular details of Eph–ephrin recognition have been previously revealed and it has been documented that ephrin binding …
