Ketosis Prevents Abdominal Aortic Aneurysm Rupture Through C-C Chemokine Receptor Type 2 Downregulation And Enhanced Extracellular Matrix Balance, Sergio Sastriques-Dunlop, Santiago Elizondo-Benedetto, Batool Arif, Rodrigo Meade, Mohamed S Zaghloul, Hannah Luehmann, Gyu S Heo, Sean J English, Yongjian Liu, Mohamed A Zayed

2020-Current year OA Pubs

Abdominal aortic aneurysms (AAAs) are prevalent with aging, and AAA rupture is associated with increased mortality. There is currently no effective medical therapy to prevent AAA rupture. The monocyte chemoattractant protein (MCP-1)/C-C chemokine receptor type 2 (CCR2) axis critically regulates AAA inflammation, matrix-metalloproteinase (MMP) production, and extracellular matrix (ECM) stability. We therefore hypothesized that a diet intervention that can modulate CCR2 axis may therapeutically impact AAA risk of rupture. Since ketone bodies (KBs) can trigger repair mechanisms in response to inflammation, we evaluated whether systemic ketosis in vivo could reduce CCR2 and AAA progression. Male Sprague-Dawley rats underwent surgical AAA …

Mechanical Stiffness And Anisotropy Measured By Mre During Brain Development In The Minipig, Shuaihu Wang, Charlotte A Guertler, Ruth J Okamoto, Curtis L Johnson, Matthew D J Mcgarry, Philip V Bayly

2020-Current year OA Pubs

The relationship between brain development and mechanical properties of brain tissue is important, but remains incompletely understood, in part due to the challenges in measuring these properties longitudinally over time. In addition, white matter, which is composed of aligned, myelinated, axonal fibers, may be mechanically anisotropic. Here we use data from magnetic resonance elastography (MRE) and diffusion tensor imaging (DTI) to estimate anisotropic mechanical properties in six female Yucatan minipigs at ages from 3 to 6 months. Fiber direction was estimated from the principal axis of the diffusion tensor in each voxel. Harmonic shear waves in the brain were excited …

Treatment failure in joint infections is associated with fibrinous, antibiotic-resistant, floating and tissue-associated Staphylococcus aureus aggregates formed in synovial fluid (SynF). We explore whether antibiotic activity could be increased against Staphylococcus aureus aggregates using ultrasound-triggered microbubble destruction (UTMD), in vitro and in a porcine model of septic arthritis. In vitro, when bacterially laden SynF is diluted, akin to the dilution achieved clinically with lavage and local injection of antibiotics, amikacin and ultrasound application result in increased bacterial metabolism, aggregate permeabilization, and a 4-5 log decrease in colony forming units, independent of microbubble destruction. Without SynF dilution, amikacin + UTMD does …

2020-Current year OA Pubs

Coronaviruses (CoVs) comprise a group of important human and animal pathogens. Despite extensive research in the past 3 years, the host innate immune defense mechanisms against CoVs remain incompletely understood, limiting the development of effective antivirals and non-antibody-based therapeutics. Here, we performed an integrated transcriptomic analysis of porcine jejunal epithelial cells infected with porcine epidemic diarrhea virus (PEDV) and identified cytidine/uridine monophosphate kinase 2 (CMPK2) as a potential host restriction factor. CMPK2 exhibited modest antiviral activity against PEDV infection in multiple cell types. CMPK2 transcription was regulated by interferon-dependent and interferon regulatory factor 1 (IRF1)-dependent pathways post-PEDV infection. We demonstrated …

Agricultural Dust Derived Bacterial Extracellular Vesicle Mediated Inflammation Is Attenuated By Dha, Art J. Heires, Derrick R. Samuelson, Daniel Villageliu, Tara M. Nordgren, Debra J. Romberger

Journal Articles: Pulmonary & Critical Care Med

Dietary long-chain omega-3 polyunsaturated fatty acids (n-3 PUFA) and their pro-resolving metabolites are protective against atherosclerotic disease, and ameliorate systemic inflammatory conditions including lupus erythematosus, psoriasis, and bronchial asthma. Organic bioaerosol inhalation is a common and injurious hazard associated with agricultural occupations such as work in swine concentrated animal feeding operations (CAFOs) and is known to increase the risk for developing respiratory conditions such as asthma and COPD. Nearly all cells secrete membrane-bound vesicles (extracellular vesicles, EVs) that have the capacity to transmit protein, nucleic acid, and lipid signaling mediators between cells. Using a polymer-based isolation technique (ExoQuick, PEG) followed …

A Standardized Nomenclature For Mammalian Histone Genes., Ruth L Seal, Paul Denny, Elspeth A Bruford, Anna K Gribkova, David Landsman, William F Marzluff, Monica Mcandrews, Anna R Panchenko, Alexey K Shaytan, Paul B Talbert

Faculty Research 2022

Histones have a long history of research in a wide range of species, leaving a legacy of complex nomenclature in the literature. Community-led discussions at the EMBO Workshop on Histone Variants in 2011 resulted in agreement amongst experts on a revised systematic protein nomenclature for histones, which is based on a combination of phylogenetic classification and historical symbol usage. Human and mouse histone gene symbols previously followed a genome-centric system that was not applicable across all vertebrate species and did not reflect the systematic histone protein nomenclature. This prompted a collaboration between histone experts, the Human Genome Organization (HUGO) Gene …

Blood-Brain Barrier Opening In A Large Animal Model Using Closed-Loop Microbubble Cavitation-Based Feedback Control Of Focused Ultrasound Sonication, Chih-Yen Chien, Lu Xu, Christopher Pham Pacia, Yimei Yue, Hong Chen

2020-Current year OA Pubs

Focused ultrasound (FUS) in combination with microbubbles has been established as a promising technique for noninvasive and localized Blood-brain barrier (BBB) opening. Real-time passive cavitation detection (PCD)-based feedback control of the FUS sonication is critical to ensure effective BBB opening without causing hemorrhage. This study evaluated the performance of a closed-loop feedback controller in a porcine model. Calibration of the baseline cavitation level was performed for each targeted brain location by a FUS sonication in the presence of intravenously injected microbubbles at a low acoustic pressure without inducing BBB opening. The target cavitation level (TCL) was defined for each target …

Repeated Endo-Tracheal Tube Disconnection Generates Pulmonary Edema In A Model Of Volume Overload: An Experimental Study, Bhushan H Katira, Doreen Engelberts, Sheena Bouch, Jordan Fliss, Luca Bastia, Kohei Osada, Kim A Connelly, Marcelo B P Amato, Niall D Ferguson, Wolfgang M Kuebler, Brian P Kavanagh, Laurent J Brochard, Martin Post

2020-Current year OA Pubs

BACKGROUND: An abrupt lung deflation in rodents results in lung injury through vascular mechanisms. Ventilator disconnections during endo-tracheal suctioning in humans often cause cardio-respiratory instability. Whether repeated disconnections or lung deflations cause lung injury or oedema is not known and was tested here in a porcine large animal model.

METHODS: Yorkshire pigs (~ 12 weeks) were studied in three series. First, we compared PEEP abruptly deflated from 26 cmH

RESULTS: As compared to PEEP 5 cmH

CONCLUSION: Single abrupt deflation from high PEEP, and repeated short deflations from moderate PEEP cause pulmonary oedema, impaired oxygenation, and increased PVR, in this …

Hydraulic Permeability And Compressive Properties Of Porcine And Human Synovium, Milad Rohanifar, Benjamin B Johnston, Alexandra L Davis, Young Guang, Kayla Nommensen, James A J Fitzpatrick, Christine N Pham, Lori A Setton

2020-Current year OA Pubs

The synovium is a multilayer connective tissue separating the intra-articular spaces of the diarthrodial joint from the extra-synovial vascular and lymphatic supply. Synovium regulates drug transport into and out of the joint, yet its material properties remain poorly characterized. Here, we measured the compressive properties (aggregate modulus, Young's modulus, and Poisson's ratio) and hydraulic permeability of synovium with a combined experimental-computational approach. A compressive aggregate modulus and Young's modulus for the solid phase of synovium were quantified from linear regression of the equilibrium confined and unconfined compressive stress upon strain, respectively (H

USDA Wildlife Services: Staff Publications

BACKGROUND: Lethal removal of invasive species, such as wild pigs (Sus scrofa), is often the most efficient approach for reducing their negative impacts. Wild pigs are one of the most widespread and destructive invasive mammals in the USA. Lethal management techniques are a key approach for wild pigs and can alter wild pig spatial behavior, but it is unclear how wild pigs respond to the most common removal technique, trapping.We investigated the spatial behavior of wild pigs following intensive removal of conspecifics via trapping at three sites within the Savannah River Site, SC, USA. We evaluated changes in …

A Framework For Surveillance Of Emerging Pathogens At The Human-Animal Interface: Pigs And Coronaviruses As A Case Study, Kim M. Pepin, Ryan S. Miller, Mark Q. Wilber

USDA Wildlife Services: Staff Publications

Pigs (Sus scrofa) may be important surveillance targets for risk assessment and risk-based control planning against emerging zoonoses. Pigs have high contact rates with humans and other animals, transmit similar pathogens as humans including CoVs, and serve as reservoirs and intermediate hosts for notable human pandemics. Wild and domestic pigs both interface with humans and each other but have unique ecologies that demand different surveillance strategies. Three fundamental questions shape any surveillance program: where, when, and how can surveillance be conducted to optimize the surveillance objective? Using theory of mechanisms of zoonotic spillover and data on risk factors, …

Reconciling Environmental Justice With Climate Change Mitigation: A Case Study Of Nc Swine Cafos, D. Lee Miller, Ryke Longest

Faculty Scholarship

For thirty years, the swine industry has externalized severe environmental and health harms onto poor communities of color in Eastern North Carolina. This “Big Pig” problem is caused by the confinement, consolidation, and concentration of industrial hog operations within the low, flat, and economically marginalized Coastal Plain. Big Pig’s rise was not inevitable. As recently as 1982, more than 11,000 small swine farms freckled nearly all of North Carolina’s 100 counties. Then came the “boom” of consolidation and industrialization that transformed hog production into a highly consolidated and vertically integrated industry.

Performance Differences Between Two Groups Of Commercial Pigs Following Experimental Infection With Prrs Virus 1-7-4, Erin Little

Electronic Theses and Dissertations

Porcine reproductive and respiratory syndrome virus (PRRSV) is the costliest swine disease in North America. Vaccines and management alone have not been effective in controlling this disease. Genetic selection for resilience may be a complimentary approach for controlling PRRSV. The objective of this study was to estimate performance differences between two groups of pigs from the same commercial line following infection with PRRSV 1-7-4: 1) pigs sired by boars selected based on a standard index (TN-S), which emphasized feed efficiency and carcass quality; and 2) pigs sired by boars selected based on an experimental index (TN-E), which emphasized feed intake, …

Community and Family Health Faculty Publications

The human papillomavirus (HPV) is a sexually transmitted infection and causes most oropharyngeal (e.g., throat) and anogenital (e.g., anal, cervical) cancers. Research indicates low knowledge about the link between HPV and cancer among the general population, and similar low knowledge of HPV among individuals diagnosed with HPV-associated cancers. This is important because HPV status can have implications for treatment, prognosis, and future sexual decisions. Using a health literacy framework, this study explored how patients diagnosed with HPV-associated cancers accessed, understood, appraised, and applied HPV information. We conducted 27 in-depth interviews with patients seeking care at a comprehensive cancer center; and …

Anticoagulant Rodenticide Residues In Game Animals In California, Stella C. Mcmillin, Robert H. Poppenga, Shannon C. Chandler, Deana L. Clifford

USDA Wildlife Services: Staff Publications

Anticoagulant rodenticides (ARs) are used to control rodents around homes, buildings, and in agriculture. They have been found widely in predatory and scavenging wildlife as a result of secondary exposure and less commonly in herbivores and omnivores from primary exposure. While predators and scavengers have been monitored for AR exposure, very little information is available about AR residues in edible muscle tissue of game animals. Game animals may be exposed to ARs through direct consumption of bait, ingestion of contaminated food or vegetation, or consumption of contaminated prey items. Carcasses of three species of game animals (black bear, wild pigs, …
