Regulation Of Food Intake By Connexin43 Via Adipocyte-Sensory Neuron Electrical Synapses, Xi Chen, Xing Fang, Hong Zhou, Jieyi Meng, Yang He, Leon G Straub, Andrew Lemoff, Clair Crewe, Shangang Zhao, Yong Xu, Yi Zhu

Duncan NRI Faculty and Staff Publications

Background and objective: Connexin43 (Cx43), encoded by Gja1, forms gap junctions between adjacent cells. In adipose tissue, it is upregulated during adipose beiging while downregulated by high-fat-diet (HFD) feeding. Adipocyte-specific Gja1 overexpression enhances adipose tissue beiging in response to mild cold stress of room temperature. Moreover, those mice display a surprising decrease in food intake, but the mechanism remains unclear. This study investigates how adipocyte Cx43 influences feeding behavior.

Methods: Mice with adipose tissue-specific Gja1 overexpression (Adipoq-Cx43) were fed with HFD. Food intake, weight gain, substrate utilization, and serum lipolysis were assessed. RNA-seq, proteomics, and cytokine measurements were employed to …

Post-Translational Modification Of H2b C-Terminal Helix Regulates Nucleosome Interactions And Chromatin Signaling, Yani Zhao, Anh Nguyen, Eyla C Arteaga, Aleksandra Skrajna, Krzysztof Krajewski, Dennis Goldfarb, Robert K Mcginty

2020-Current year OA Pubs

Histone H2B contains a highly conserved C-terminal (H2B αC) helix that has been implicated in chromatin interactions and dynamics. The H2B αC helix comprising residues 105-125 is positioned adjacent to a major site of nucleosome interactions called the acidic patch. Despite individual structural studies highlighting interactions between chromatin proteins and the H2B αC helix, the general role of the helix in mediating nucleosome recognition has not been explored. Moreover, many post-translational modifications (PTMs) have been identified within the H2B αC helix, but significant gaps exist in our understanding of their regulatory potential. In this study, we employed nucleosome affinity proteomics …

Creating The Thomas Mcrae Sanitorium For Negros: Race, Contagion, And Space In Jim Crow Arkansas, Shauna Gibbons

The Ozark Historical Review

The Thomas McRae Memorial Sanatorium for Negroes, located in Alexander, Arkansas, opened its doors in 1931 as the only resource for the entire state’s population of consumptive African Americans. It was touted as one of the best of its kind under the supervision of Dr Hugh A. Browne. But its “kind” was a facility intended for individuals whom whites in the medical and political establishment viewed not only as second class citizens but as biologically and medically different.

Improving Glucose Monitoring Using Smart Phone-Based Monitoring Devices, Yetunde Ogunjumelo

Walden Dissertations and Doctoral Studies

The use of continuous glucose monitoring devices (CGMs) has become essential for improved glycemic control and the prevention of complications among patients. However, a significant number of nurses lack proper training in supporting patients with these devices, leading to a gap in practice. The project addressed the problem of insufficient staff knowledge and confidence in supporting patients with smartphone based CGMs through staff education on CGMs and evidence-based training on glucose monitoring techniques, interpretation of monitoring results, and patient education strategies. The question that guided the project was as follows: Does implementing a staff education program on smartphone-based CGMs improve …

Pharmacy Faculty Articles and Research

Air pollution is a significant public health issue that impacts lung health, particularly in vulnerable populations such as children, the elderly, and individuals with pre-existing respiratory conditions. Both natural and anthropogenic sources of air pollution give rise to a variety of toxic compounds, including particulate matter (PM), ozone (O₃), sulfur dioxide (SO₂), nitrogen dioxide (NO₂), carbon monoxide (CO), and polycyclic aromatic hydrocarbons (PAHs). Exposure to these pollutants is strongly associated with the development and exacerbation of respiratory diseases, including asthma, chronic obstructive pulmonary disease (COPD), lung cancer, and idiopathic pulmonary fibrosis (IPF). Notably, early life exposure to pollutants such as …

Human Adipose Stem Cell-Derived Small Extracellular Vesicles Modulate Glial Cell Response In Aged And Young Tbi Mouse Models, Salma S. Abdelmaboud

USF Tampa Graduate Theses and Dissertations

Traumatic brain injury (TBI) is a leading cause of long-term neurological impairment, with aging significantly increasing vulnerability and worsening outcomes. Older individuals experience greater cognitive and motor deficits after TBI and often show diminished responses to therapeutic interventions. Both aging and TBI independently promote heightened neuroinflammation and cognitive dysfunction, increasing susceptibility to poor recovery. This study investigated the therapeutic potential of small extracellular vesicles (sEVs) derived from human adipose-derived stem cells (hASCs) to promote neurological recovery and modulate neuroinflammation in a mouse model of TBI. Male C57BL/6 mice aged 3, 15, and 20 months underwent controlled cortical impact (CCI) and …

Evidence links air pollution to dementia, yet its role in Lewy body dementia (LBD) remains unclear. Here we showed in a cohort of 56.5 million individuals across the U.S. that PM2.5 exposure raises LBD risk. Mechanistically, we found PM2.5 exposure led to brain atrophy in wild-type mice, an effect not seen in α-synuclein (αSyn)-deficient mice. PM2.5 exposure generated a highly pathogenic αSyn strain, PM-PFF, with enhanced proteinase K-resistance and neurotoxicity, resembling αSyn LBD strains. PM2.5 samples from China, the U.S., and Europe consistently induced proteinase-resistant αSyn strains and in vivo pathology. Transcriptomic analyses revealed shared responses between PM2.5-exposed mice and …

HPV integration disrupts host genomic structure and expression, but whether these alterations promote cancer development remains unclear. Multiple genomic analyses of oropharyngeal cancers identified several host fusion genes, including recurrent FGFR3-TACC3 fusions, expressed from rearranged genomic loci adjacent to HPV integration sites. Evolutionary modeling implicated integration of virus concatemers into the host genome as a common initiating event in fusion formation. Co-expression of HPV16 E6/E7 and FGFR3-TACC3, but neither alone, was sufficient for tumor development in both xenograft and syngeneic mouse models and led to unique transcriptional programs implicated in carcinogenesis. FGFR3-TACC3 expression decreased the ubiquitination and degradation of …

The Impact Of Communication And Job Satisfaction On Registered Nurse Turnover, Kingsley Kenechukwu Onyeama

Walden Dissertations and Doctoral Studies

Health care leaders are challenged with ongoing nursing shortages. The purpose of this quantitative, correlational study was to examine the impact of communication and job satisfaction on registered nurses’ turnover intentions. The conceptual framework integrated Maslow’s Hierarchy of Needs, Herzberg and Mausner’s Motivation-Hygiene Theory, and Social Exchange Theory. Two research questions guided the study: the relationship between communication variables and intent to leave a healthcare organization, and the relationship between job satisfaction and intent to leave. A randomized sample of 156 registered nurses in California, aged 23 to 65 and identified through the California Nurses Database, was recruited via SurveyMonkey. …


The Causal Pivot: A Structural Approach To Genetic Heterogeneity And Variant Discovery In Complex Diseases, Chad A Shaw, C J Williams, Taotao Tan, Daniel Illera, Nicholas Di, Joshua M Shulman, John W Belmont Sep 2025

The Causal Pivot: A Structural Approach To Genetic Heterogeneity And Variant Discovery In Complex Diseases, Chad A Shaw, C J Williams, Taotao Tan, Daniel Illera, Nicholas Di, Joshua M Shulman, John W Belmont

Center on Aging Staff Publications

We present the Causal Pivot (CP) as a structural causal model (SCM) for analyzing genetic heterogeneity in complex diseases. The CP leverages an established causal factor or factors to detect the contribution of additional suspected causes. Specifically, polygenic risk scores (PRSs) serve as known causes, while rare variants (RVs) or RV ensembles are evaluated as candidate causes. The CP incorporates outcome-induced association by conditioning on disease status. We derive a conditional maximum-likelihood procedure for binary and quantitative traits and develop the Causal Pivot likelihood ratio test (CP-LRT) to detect causal signals. Through simulations, we demonstrate the CP-LRT’s robust power and …

2020-Current year OA Pubs

Preconditioning regimens are essential for the immunologic success of cell therapies like CAR T cells. Nevertheless, their effect on cancer vaccines is underexplored, and preconditioning regimens are generally absent from cancer vaccine clinical trials. To address this knowledge gap, we evaluated the impact of various preconditioning strategies on dendritic cell (DC) vaccine efficacy in a murine tumor model. Mice bearing syngeneic tumors received preconditioning with 2 Gy low-dose radiation therapy (LD RT; whole-body or tumor-only), cyclophosphamide, paclitaxel, LD RT plus cyclophosphamide, or no preconditioning, followed by administration of antigen-loaded DCs. Whether whole-body or tumor-directed, LD RT preconditioning significantly enhanced vaccine-induced …

Louisiana State University Health New Orleans hosts a 3-day program, the Fundamentals of Vascular Surgery (FVS) Symposium, during which vascular trainees from across the nation can participate in didactic and hands-on lessons with an emphasis on procedures less frequently performed during residency, taught by attending surgeons from various institutions. The objective of this study was to examine the effect of the FVS Symposium on participant confidence in endovascular and open procedures and evaluate any differences between junior and senior level residents. …

Anhedonia is increasingly recognized as a transdiagnostic risk factor for psychopathology. New evidence demonstrates that anhedonia is present in infancy and early childhood. Structural variability in striatal regions involved in reward processing and pleasure seeking is concurrently linked to anhedonia, yet few studies have examined whether striatal differences presage anhedonia, and none have examined prospective associations before middle childhood. The present study examined whether neuroanatomical markers that confer risk for anhedonia can be detected as early as the neonatal period. Specifically, we tested whether the volume of striatal regions in neonates predicted the emergence of infant anhedonic behaviors at six …

The practice problem I identified was a rising number of resident falls throughout the past 6-12 months at a 29-bed assisted living facility (ALF). The organization requested an education program on evidence-based practices on fall prevention in older adults. I used the project question to explore if an education program would increase the knowledge of the staff and caregivers at the ALF. Numerous sources of evidence supported the practice guidelines including fall risk assessment tools. During the facility monthly staff meeting, participants completed a six-question knowledge assessment on falls. The participants completed the same assessment after the education program, as …

Data on health equity to inform societally relevant evidence based decisions and policy making are lacking in the research literature. Observational studies have the potential to provide data on health equity. Yet, guidance on how to report health equity data and considerations in observational research is inadequate. The STROBE-Equity extension addresses this gap by providing a structured set of criteria to enhance the reporting of health equity data and considerations.
