Mitochondrial dysfunction and reactive oxygen species (ROS) accumulation within the substantia nigra pars compacta (SNpc) are central drivers of dopaminergic (DA) neuron death in Parkinson's disease (PD). Guanylyl cyclases and their second messenger cyclic (c)GMP support mitochondrial function, protecting against ROS and promoting cell survival in several tissues. However, the role of the guanylyl cyclase-cGMP axis in defining the vulnerability of DA neurons in the SNpc in PD remains unclear, in part due to the challenge of manipulating cGMP levels selectively in midbrain DA neurons. In that context, guanylyl cyclase C (GUCY2C), a receptor primarily expressed by intestinal epithelial cells, …

BACKGROUND: Digital neuropsychological tests reliably capture real-time, process-based behavior that traditional paper/pencil tests cannot detect, enabling earlier detection of neurodegenerative illness. We assessed relations between informant-based subtle and mild functional decline and process-based features extracted from the digital Trail Making Test-Part B (dTMT-B).

METHODS: A total of 321 community-dwelling participants (56.0% female) were assessed with the Functional Activities Questionnaire (FAQ) and the dTMT-B. Three FAQ groups were constructed: FAQ = 0 (unimpaired); FAQ = 1-4 (subtle impairment); FAQ = 5-8 (mild impairment).

Results: Compared to the FAQ-unimpaired group, other groups required longer pauses inside target circles (p < 0.050) and produced more total pen strokes to complete the test (p < 0.016). FAQ-subtle participants required more time to complete the entire test (p …


Technology To Support Aging In Place: The Perspective Of Caregivers, Sophie Meng Apr 2024

Technology To Support Aging In Place: The Perspective Of Caregivers, Sophie Meng

Capstone Research Posters

As the world population ages, more older adults prefer to age in a place which offers them better life qualities and autonomy but demands increased commitments of caregivers. The development of technology can be great aid in daily lives yet significant gaps persist in supporting older adults with impaired cognition aging in place. This study aimed to explore the perspective of caregivers on technology when assisting cognition impaired older adults at home. It sought to understand the needs of the caregivers in this context. The study also briefly addressed Artificial Intelligence (AI) in caregiving, considering its growing use. Five caregivers …

Expanded intronic G4C2 repeats in the C9ORF72 gene cause amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). These intronic repeats are translated through a non-AUG-dependent mechanism into five different dipeptide repeat proteins (DPRs), including poly-glycine-arginine (GR), which is aggregation-prone and neurotoxic. Here, we report that Kapβ2 and GR interact, co-aggregating, in cultured neurons in-vitro and CNS tissue in-vivo. Importantly, this interaction significantly decreased the risk of death of cultured GR-expressing neurons. Downregulation of Kapβ2 is detrimental to their survival, whereas increased Kapβ2 levels mitigated GR-mediated neurotoxicity. As expected, GR-expressing neurons displayed TDP-43 nuclear loss. Raising Kapβ2 levels …


The Binding And Mechanism Of A Positive Allosteric Modulator Of Kv3 Channels, Qiansheng Liang, Gamma Chi, Leonardo Cirqueira, Lianteng Zhi, Agostino Marasco, Nadia Pilati, Martin Gunthorpe, Giuseppe Alvaro, Charles Large, David Sauer, Werner Treptow, Manuel Covarrubias Mar 2024

Small-molecule modulators of diverse voltage-gated K+ (Kv) channels may help treat a wide range of neurological disorders. However, developing effective modulators requires understanding of their mechanism of action. We apply an orthogonal approach to elucidate the mechanism of action of an imidazolidinedione derivative (AUT5), a highly selective positive allosteric modulator of Kv3.1 and Kv3.2 channels. AUT5 modulation involves positive cooperativity and preferential stabilization of the open state. The cryo-EM structure of the Kv3.1/AUT5 complex at a resolution of 2.5 Å reveals four equivalent AUT5 binding sites at the extracellular inter-subunit interface between the voltage-sensing and pore domains of the …


Enhancing Workplace Neuro Health And Productivity: The Synergy Of Wearable Technology With Biophilic And Oxygenation Strategies, Piper Hutson, James Hutson Feb 2024

Enhancing Workplace Neuro Health And Productivity: The Synergy Of Wearable Technology With Biophilic And Oxygenation Strategies, Piper Hutson, James Hutson

Faculty Scholarship

In the contemporary workplace, where a staggering 62% of employees reported experiencing burnout in 2023 according to a Medium article, the integration of wearable technology with biophilic and oxygenation strategies emerges as a vital Neurohemal initiative. This approach is particularly relevant for supporting neurodivergent individuals, as well as those recovering from stroke and long-COVID, in the context of return-to-office mandates. The article underscores the significance of research on increased hydrostatic pressure in circulation, particularly its impact on spinal and spinal cord blood flow during water immersion. This insight lays the groundwork for innovations like non-wet water massage devices, which could …


The Effect Of Caffeine On Bee Behavior: A Progressive Ratio Study, Kayle Cohen, Becky Hansis-O'Neill, Aimee Dunlap Dr Jan 2024

The Effect Of Caffeine On Bee Behavior: A Progressive Ratio Study, Kayle Cohen, Becky Hansis-O'Neill, Aimee Dunlap Dr

Undergraduate Research Symposium

This presentation focuses on the effect of caffeine on bee behavior using behavioral pharmacology methodologies. Researchers trained bumblebees to drink out of artificial flowers, then administered sucrose nectar or caffeinated sucrose nectar during a schedule of progressive and fixed ratios. The finding suggests that caffeine did increase the number of rewards during the fixed ratio, but not in the progressive ratio. However, research is still ongoing as bees continue to be tested..

BACKGROUND: Smartphone-based cognitive assessments have emerged as promising tools, bridging gaps in accessibility and reducing bias in Alzheimer disease and related dementia research. However, their congruence with traditional neuropsychological tests and usefulness in diverse cohorts remain underexplored.

METHODS AND RESULTS: A total of 406 FHS (Framingham Heart Study) and 59 BHS (Bogalusa Heart Study) participants with traditional neuropsychological tests and digital assessments using the Defense Automated Neurocognitive Assessment (DANA) smartphone protocol were included. Regression models investigated associations between DANA task digital measures and a neuropsychological global cognitive

CONCLUSIONS: Our findings demonstrate that smartphone-based cognitive assessments exhibit concurrent validity with a …

Enhancing Proprioception And Regulating Cognitive Load In Neurodiverse Populations Through Biometric Monitoring With Wearable Technologies, James Hutson, Piper Hutson

Faculty Scholarship

This paper considers the realm of wearable technologies and their prospective applications for individuals with neurodivergent conditions, specifically Autism Spectrum Disorders (ASDs). The study undertakes a multifaceted analysis that encompasses biomarker sensing technologies, AI-driven biofeedback mechanisms, and haptic devices, focusing on their implications for enhancing proprioception and social interaction among neurodivergent populations. While wearables offer a range of opportunities for societal advancement, a discernable gap remains: a scarcity of consumer-oriented applications tailored to the unique physiological and psychological needs of these individuals. Key takeaways underscore the emergent promise of tailored auditory stimuli in workplace dynamics and the efficacy of haptic …
