Differential Speed And Accuracy Trade-Off In Working Memory Retrieval And Bilateral Precuneus Between Older Men And Women, Darlingtina K. Esiaka, Stephanie Strothkamp, Aghayeeabianeh Banafsheh, Lucas S. Broster, David K. Powell, Gregory Jicha, Yang Jiang

Behavioral Science Faculty Publications

Background

Despite various hypotheses, including differences in longevity, hormones, genetics, and neuroanatomy, the reasons for the higher prevalence of Alzheimer's disease in older women compared to men remain unclear. Emerging evidence suggests that the precuneus, a key region of the default mode network, is linked to internally focused processes like memory retrieval. We examined the relationship between precuneus volumes and task performance (accuracy and reaction time) during working memory retrievals in cognitively normal older adults.

Method

A cohort of older participants (N = 45; 25 women; Mage = 77) from the University of Kentucky Alzheimer's Disease Research Center …

Examining The Communication Work Of Women Who Have Tested Brca-Positive: “I Feel This Responsibility To Let People Know”, Summer C. Martin, Allison M. Scott, Anne M. Stone

Communication Faculty Publications

Inheriting a pathogenic variant in the BRCA1 or BRCA2 gene considerably increases a woman's risk levels for developing breast and ovarian cancer. In addition to serious physical health implications, women with a BRCA pathogenic variant may face psychosocial challenges, including those related to navigating the often demanding process of communicating about topics regarding BRCA with family and other social network members. Based on in-depth interviews with 24 women who tested BRCA-positive, we found that—consistent with the conceptualization of communication work articulated by Donovan-Kicken et al. (2012) as an extension of the theory of illness trajectories (Corbin & Strauss, 1988)—the labor …

The alarmingly high prevalence of obesity in older adults coupled with the negative health effects of chronic inflammation in both obesity and aging highlight the importance of studies investigating the impacts of obesity on age-related inflammation. Since shifts in peripheral T-cell metabolism and function drive systemic inflammation in both obesity and aging, we hypothesize that obesity impacts the Th17-dominated inflammaging profile we identified in lean subjects and thus modifies the anti-inflammatory effects of geroprotective drugs like metformin. New cytokine profiling data showed that CD4+ T cells from older people with obesity generate a profile that specifically excludes Th17 cytokines. Metformin …

Bilirubin Hepatic And Intestinal Transport And Catabolism: Physiology, Pathophysiology, And Benefits, Zachary A. Kipp, Sally N. Pauss, Genesee J. Martinez, Terry D. Hinds, Jr., Wang-Hsin Lee

Pharmacology and Nutritional Sciences Faculty Publications

Bilirubin, a metabolite derived from heme degradation, has traditionally been regarded as a waste product and a marker of liver injury. However, increasing evidence suggests that bilirubin also functions as a hormone, and reduced levels are associated with metabolic dysfunction. Studies have shown a strong association between low circulating bilirubin levels and an increased risk of metabolic disorders and cardiovascular disease. To advance bilirubin-based treatment strategies, it is essential to elucidate the mechanisms underlying bilirubin transport and metabolism. Therefore, we provide an in-depth discussion of bilirubin production and its subsequent fates, with a particular focus on the transport between the …

Cd47: An Immunoregulatory Nexus In Liver And Gastrointestinal Disorders, Josephine Otuagomah, Alana Newcomb, Taesik Gwag, Shuxia Wang

Pharmacology and Nutritional Sciences Faculty Publications

Cluster of differentiation 47 (CD47) is a widely expressed transmembrane protein that serves as a critical immunoregulatory checkpoint in both homeostatic and pathological conditions of the digestive system. It interacts with signal regulatory protein alpha to send a ‘do not eat me’ signal, thereby preventing phagocytosis and shaping immune responses. Beyond immunity, CD47 also influences cell death, growth and metabolism through interactions with integrins and thrombospondin-1. Recent studies implicate CD47 as a central nexus in the pathogenesis of diverse liver and gastrointestinal disorders, including metabolic dysfunction-associated steatotic liver disease, metabolic dysfunction-associated steatohepatitis, inflammatory bowel disease, liver ischaemia-reperfusion injury, drug-induced liver …

Brain signaling of calcineurin (CN) and nuclear factor of activated T-cells (NFAT) transcription factor increases in Alzheimer disease (AD) and is associated with synaptic loss, neurodegeneration, neuroinflammation, amyloid-β (Aβ) production, and cognitive decline. CN/NFAT inhibitors ameliorate these neuropathologies in mouse models of AD. Further, chronic use of tacrolimus in transplant patients reduces risk of AD. Beagles naturally develop Aβ plaques and cognitive dysfunction. We evaluated the impact of FDA-approved CN inhibitor, tacrolimus, and experimental NFAT inhibitor, Q134R, on cognitive outcomes during a three-year prevention study in 37 middle-aged beagles. While beagles treated with CN/NFAT inhibitors showed differences in the pattern …

Ceramide Homeostasis In Hepatic Lipid Droplets, Leobarda Robles-Martinez, Kylie H. Morin, Mariana Nikolova‑Karakashian

Physiology Faculty Publications

Almost all eukaryotic cells have the capacity to form lipid droplets (LDs) in conditions of excess energy. Traditionally thought to be just inert fat reservoirs, LDs have recently emerged as important metabolic regulators of cellular stress response that buffer excess free fats and protect cells from lipotoxicity. Ceramide is a bioactive lipid that accumulates in metabolic tissues during fat oversupply. Emerging evidence suggests that sphingolipids and sphingolipid-metabolizing enzymes are found in the LDs and affect LD biogenesis and functions. This article aims to summarize the evidence, delineate some plausible functions of ceramide in hepatic LD biogenesis, and illustrate some of …

Blood-based biomarkers continue to be explored for disease detection, monitoring of progression, and therapeutic outcomes as the diagnostic determination of Alzheimer’s Disease in Down Syndrome (DS-AD) remains challenging in clinical settings. This perspective highlights the current status of this effort. Overall, amyloid (A), tau (T), and neurodegeneration (AT[N]) blood-based biomarkers have been shown to increase with disease pathology for individuals with DS. Phosphorylated tau biomarkers (p-tau217, p-tau181) have been consistently shown to track disease progression for DS-AD and are likely good candidates for use in clinical settings. Biomarkers of inflammation (glial fibrillary acidic protein) also show promise; however, additional work …


Lgbt People's Sense Of Linked Fate: Belonging And Utility, Kay Hales Jan 2025

Lgbt People's Sense Of Linked Fate: Belonging And Utility, Kay Hales

Theses and Dissertations--Political Science

This is a three study dissertation. While the LGBT community is often referred to as a monolith, research suggests that it may be separate subgroups under one umbrella. Linked fate is the sense that what happens to one member of a group will affect all other group members with consequences for political behavior. While research on racial identity groups suggests that members often feel a sense of linked fate with other group members, this research has not been generalized or explored in the LGBT community. This study empirically explores whether there is a sense of linked fate in the LGBT …

Bourbon County has a low physical activity rate. A program has been implemented to increase rates of physical activity. An evaluation has been performed using the CDC’s 6-step program evaluation process framework.

According the the framework, two recommendations were made. The first one is to increase access to parks or exercise facilities for those outside of Paris city limits. The second one is to increase the number of indoor facilities for people to use during the cold, winter months.
