Patterns Of Interdisciplinary Collaboration Resemble Biogeochemical Relationships In The Mcmurdo Dry Valleys, Antarctica: A Historical Social Network Analysis Of Science, 1907–2016, Stephen M. Chignell, Adrian Howkins, Poppie Gullett, Andrew G. Fountain

Geology Faculty Publications and Presentations

Co-authorship networks can provide key insights into the production of scientific knowledge. This is particularly interesting in Antarctica, where most human activity relates to scientific research. Bibliometric studies of Antarctic science have provided a useful understanding of international and interdisciplinary collaboration, yet most research has focused on broad-scale analyses over recent time periods. Here, we take advantage of a ‘Goldilocks’ opportunity in the McMurdo Dry Valleys, an internationally important region of Antarctica and the largest ice-free region on the continent. The McMurdo Dry Valleys have attracted continuous and diverse scientific activity since 1958. It is a geographically confined region with …

Glucocentric Drugs In Cardiovascular Disease Protection And Heart Failure, Khawaja M Talha, Gregg C Fonarow, Salim S Virani, Javed Butler

Faculty, Staff and Students Publications

Evidence for cardiovascular outcomes with older-generation antihyperglycemic drugs in the management of type 2 diabetes is based on aggregated data from prior randomized controlled trials and observational studies that were not focused on prespecified cardiovascular end points. Newer antihyperglycemic medications have undergone a rigorous evaluation of cardiovascular outcomes through randomized controlled trials since the US Food and Drug Administration imposed a mandatory requirement for all glucose-lowering drugs in 2008. The three classes of drugs that have been most extensively studied are dipeptidyl peptidase 4 inhibitors, glucagon-like peptide 1 receptor agonists, and sodium-glucose cotransporter-2 (SGLT2) inhibitors, the latter two reporting significant …

Economic Benefits Of Precision Agricultural Technologies, Mohsina Jahan

Agribusiness and Applied Economics

The purpose of this research was to build a model of profitability that can be used by individual farmers to calculate the net benefits of using precision agricultural technologies on their farms. Three case farms were selected. Partial budgeting analysis is used to calculate the net profit effect of adopting precision agricultural technology bundles. Two scenarios were compared: farms adopting precision agricultural technologies and farms not adopting. Revenues and costs that differ between the two scenarios are included in the model. A six-step process was employed and @Risk was used to account for risk. Results show that adopting PA is …

Reservoir Recreation Analysis: The Effect Of Reservoir Management Agency On Recreation Participation, Mary Mena Boateng

Agribusiness and Applied Economics

Dams and reservoirs are created to provide flood control, water storage for irrigation and water supply, recreation, and hydroelectric generation. Most US reservoirs provide recreation in some form. However, there are concerns that certain reservoir/dam managers do a better job in providing recreation than others. Some agencies that manage land riparian to US reservoirs, such as the National Park Service (NPS), are dedicated to recreation development. Other agencies such as the Army Corps of Engineers (USACE) might not be interested in catering to the additional demands of recreators as a stakeholder group. Management actions such as boat access, waterfront land, …

A Horor Theory For Introspective Consciousness, Adriana Renero, Richard Brown

Publications and Research

Higher-order theories of consciousness typically account for introspection in terms of one’s higher-order thoughts being conscious, which would require a third-order thought—i.e., a thought about a thought about a mental state. In this work, we offer an alternative account of introspection that builds on the recent Higher-Order Representation of a Representation (HOROR) theory of phenomenal consciousness. According to HOROR theory, phenomenal consciousness consists in having the right kind of higher-order representation. We claim that this theory can be extended to introspection by recognizing that there is a distinctive kind of consciousness—i.e., introspective consciousness—which can be accounted for as the theory …

Non-Physician’S Challenges In Sexual And Reproductive Health Care Provision For Women Of Reproductive Age With Cancer: A Scoping Review Of Barriers And Facilitators, Qi Chen, Emma Carpenter, Kari White

Publications and Research

Purpose: The American Society of Clinical Oncology Clinical Practice guidelines recommend that non-physicians such as nurses, social workers, psychologists should be prepared to discuss fertility and sexual concerns with patients. However, literature showed that the utilization rate of sexual and reproductive care for women with cancer remained low. We conducted a scoping review to describe non-physicians’ roles, barriers and facilitators providing sexual and reproductive health (SRH) care to women of reproductive age with cancer.

Methods: We searched six databases for articles that met the following criteria: 1) English-language; 2) original research; 3) non-physician providers; 4) women with cancer under …

Are Infrared Thermography, Automated Feeding Systems, And Heart Rate Variability Measures Capable Of Characterizing Group-Housed Sow Social Hierarchies?, Dominique Sommer

Animal Sciences

Group gestation housing is becoming standard practice in commercial swine production. Although group housing promotes behavioral variability within the breeding herd, it can cause several management challenges for producers due to the establishment of the social hierarchy. Poor performance and welfare in group housed breeding stock can be attributed to the repercussions of aggression performed between dyads. The ability to quickly identify sows in the social hierarchy could be beneficial to producers for enforcing preventative actions. Precision livestock farming tools have proven to aid animal caretakers in monitoring animal health and welfare in livestock industries.The objective of this thesis was …

Rangeland Forage Growth Prediction, Logistics, Energy, And Economics Analysis And Tool Development Using Open-Source Software, Subhashree Navaneetha Srinivasagan

Agribusiness and Biosystems Engineering

Forage availability was crucial for livestock production across the United States. Rangelands occupied vast areas 31 % of land and were the primary source of forage for livestock. However, extreme climatic conditions such as drought affect rangeland forage production and pose a serious threat to the rangeland enterprise. This increases the need to monitor forage in vast rangelands and adapt to other measures such as cultivating or buying forage to balance demand and supply. Despite this need, resources (studies and tools) on rangeland forage monitoring and existing forage production, handling, and economics were scattered and scarce. Therefore, a comprehensive systematic …

Accuracy Of A Sacral Drilling With A Custom 3d Printed Drilling Guide Or Free-Hand Technique In Canine Experimental Sacroiliac Luxation, Daniel Mccarthy

LSU Master's Theses

ABSTRACT

The objective of this study was to improve the accuracy of drilling during the repair of sacroiliac luxation with a 3D-printed patient-specific drill guide (3D-GDT) compared to free-hand drilling technique (FHDT). A blinded, randomized, prospective study was performed including sixteen canine cadavers (20-25 kg) euthanized for reasons not related to the study. Dorsal, bilateral, sacroiliac luxations (SILs) were created experimentally. A pelvic CT was performed pre- and post-drilling. The FHDT was drilled followed by 3D-GDT for each sacrum. CT and 3D measurements of craniocaudal and dorsoventral angles were compared between FHDT and 3D-GDT, as well as deviations of entry …

Escaping Circularity: The Fourth Amendment And Property Law, João Marinotti

Articles by Maurer Faculty

The Supreme Court’s “reasonable expectation of privacy” test under the Fourth Amendment has often been criticized as circular, and hence subjective and unpredictable. The Court is presumed to base its decisions on society’s expectations of privacy, while society’s expectations of privacy are themselves presumed to be based on the Court’s judgements. As a solution to this problem, property law has been repeatedly propounded as an allegedly independent, autonomous area of law from which the Supreme Court can glean reasonable expectations of privacy without falling back into tautological reasoning.

Such an approach presupposes that property law is not itself circular. If …

Standing For Rivers, Mountains - And Trees - In The Anthropocene, David Takacs

Faculty Scholarship

In his well-known article, Should Trees Have Standing?—Toward Legal Rights for Natural Objects, Professor Christopher Stone proposed that courts grant nonhuman entities standing as plaintiffs so their interests may directly represented in court. In this Article, I review Stone’s ideas about standing and our relationship with the natural environment and describe the current, burgeoning, widespread trend toward granting not just standing, but legal rights and legal personhood to rivers, mountains, and other natural entities. I analyze the ways in which courts and legislatures in New Zealand, Australia, Colombia, and elsewhere are addressing concerns similar to Stone’s with expansive, even radical …

Surgical Intervention For Phlegmasia Cerulea Dolens In A 61-Year-Old Cancer Patient, Christopher Ruben-Castillo, Cesar Cuen-Ojeda, Gabriel Lopez-Peña, Javier E Anaya-Ayala, Carlos A Hinojosa

The Texas Heart Institute Journal

Phlegmasia cerulea dolens, a rare and potentially fatal complication of acute deep vein thrombosis, is characterized by substantial edema, intense pain, and cyanosis. Phlegmasia cerulea dolens may compromise limb perfusion and lead to acute ischemia, gangrene, amputation, and death. We present the case of a 61-year-old woman with a history of breast cancer who had signs and symptoms of phlegmasia cerulea dolens in her left leg. She was treated promptly with open surgical thrombectomy and sequential distal compression with use of an Esmarch bandage to ensure complete thrombus extraction. These techniques restored venous flow and saved her leg. Open surgical …

Rev-Erb Is Essential In Cardiac Fibroblasts Homeostasis, Xiaokang Luo, Shiyang Song, Lei Qi, Chih-Liang Tien, Hui Li, Weiyi Xu, Theodore Lemuel Mathuram, Thomas Burris, Yuanbiao Zhao, Zheng Sun, Lilei Zhang

Faculty, Staff and Students Publications

REV-ERB agonists have shown antifibrotic effects in the heart and other organs. The function of REV-ERB in the cardiac fibroblasts remains unstudied. Here, we characterize the functional difference of REV-ERB in mouse embryonic fibroblasts and cardiac fibroblasts using genetic deletion of REV-ERBα and ß in vitro. We show that REV-ERB α/β double deleted cardiac fibroblasts have reduced viability and proliferation, but increased migration and myofibroblasts activation. Thus, REV-ERB α/β has essential cell-autonomous role in cardiac fibroblasts in maintaining them in a healthy, quiescent state. We also show that existing REV-ERB agonist SR9009 strongly suppresses cardiac fibroblasts activation but in …

Plasma Diaphanous Related Formin 1 Levels Are Associated With Altered Glucose Metabolism And Insulin Resistance In Patients With Polycystic Ovary Syndrome: A Case Control Study, Xing Li, Mingyu Liao, Jiaqing Shao, Weixin Li, Liu Shi, Dong Wang, Juan Ni, Qiuyue Shen, Fan Yang, Guiliang Peng, Ling Zhou, Yuling Zhang, Zheng Sun, Hongting Zheng, Min Long

Faculty, Staff and Students Publications

BACKGROUND: Diaphanous related formin 1 (DIAPH1) is a novel component of advanced glycation end product (AGE) signal transduction that was recently found to participate in diabetes-related disorders, obesity, and androgen hormones. We investigated whether plasma DIAPH1 levels were a potential prognostic predictor for polycystic ovary syndrome (PCOS).

METHODS: The levels of circulating plasma DIAPH1 and indicators of glucose, insulin, lipid metabolism, liver enzymes, kidney function, sex hormones, and inflammation were measured in 75 patients with PCOS and 77 healthy participants. All of the participants were divided into normal-weight (NW) and overweight/obese (OW) subgroups. Statistical analyses were performed with R studio. …

A Steroid Receptor Coactivator Small Molecule "Stimulator" Attenuates Post-Stroke Ischemic Brain Injury, Lisa K Mcclendon, Roberto L Garcia, Tyler Lazaro, Ariadna Robledo, Viren Vasandani, Zean Aaron Evan Luna, Abhijit S Rao, Aditya Srivatsan, David M Lonard, Clifford C Dacso, Peter Kan, Bert W O'Malley

Faculty, Staff and Students Publications

Introduction: Pathologic remodeling of the brain following ischemic stroke results in neuronal loss, increased inflammation, oxidative stress, astrogliosis, and a progressive decrease in brain function. We recently demonstrated that stimulation of steroid receptor coactivator 3 with the small-molecule stimulator MCB-613 improves cardiac function in a mouse model of myocardial ischemia. Since steroid receptor coactivators are ubiquitously expressed in the brain, we reasoned that an MCB-613 derivative (MCB-10-1), could protect the brain following ischemic injury. To test this, we administered MCB-10-1 to rats following middle cerebral artery occlusion and reperfusion.

Methods: Neurologic impairment and tissue damage responses were evaluated on day …

Faculty, Staff and Students Publications

BACKGROUND: We sought to identify clinical and genetic predictors of temozolomide-related myelotoxicity among patients receiving therapy for glioblastoma.

METHODS:Patients (n = 591) receiving therapy on NRG Oncology/RTOG 0825 were included in the analysis. Cases were patients with severe myelotoxicity (grade 3 and higher leukopenia, neutropenia, and/or thrombocytopenia); controls were patients without such toxicity. A risk-prediction model was built and cross-validated by logistic regression using only clinical variables and extended using polymorphisms associated with myelotoxicity.

RESULTS: 23% of patients developed myelotoxicity (n = 134). This toxicity was first reported during the concurrent phase of therapy for 56 patients; 30 …

Quantification Of Behavioral Deficits In Developing Mice With Dystonic Behaviors., Meike E Van Der Heijden, Jason S Gill, Alejandro G Rey Hipolito, Luis E Salazar Leon, Roy V Sillitoe

Duncan NRI Faculty and Staff Publications

Converging evidence from structural imaging studies in patients, the function of dystonia-causing genes, and the comorbidity of neuronal and behavioral defects all suggest that pediatric-onset dystonia is a neurodevelopmental disorder. However, to fully appreciate the contribution of altered development to dystonia, a mechanistic understanding of how networks become dysfunctional is required for early-onset dystonia. One current hurdle is that many dystonia animal models are ideally suited for studying adult phenotypes, as the neurodevelopmental features can be subtle or are complicated by broad developmental deficits. Furthermore, most assays that are used to measure dystonia are not suited for developing postnatal mice. …

Epithelial Morphogenesis In The Drosophila Egg Chamber Requires Parvin And Ilk, Athina Keramidioti, Evgenia Golegou, Eleni Psarra, Nikolaos Paschalidis, Konstantina Kalodimou, Shinya Yamamoto, Christos Delidakis, Katerina M Vakaloglou, Christos G Zervas

Integrins are the major family of transmembrane proteins that mediate cell-matrix adhesion and have a critical role in epithelial morphogenesis. Integrin function largely depends on the indirect connection of the integrin cytoplasmic tail to the actin cytoskeleton through an intracellular protein network, the integrin adhesome. What is currently unknown is the role of individual integrin adhesome components in epithelia dynamic reorganization. Drosophila egg chamber consists of the oocyte encircled by a monolayer of somatic follicle epithelial cells that undergo specific cell shape changes. Egg chamber morphogenesis depends on a developmental array of cell-cell and cell-matrix signalling events. Recent elegant work …

An Introductory Point-Of-Care Ultrasound Curriculum For An Anesthesiology Residency Program, Susan C Lee, Edward C Yang, Jovany Cruz Navarro, Charles G Minard, Xiaofan Huang, Yi Deng

Faculty, Staff and Students Publications

INTRODUCTION: The use of point-of-care ultrasound (POCUS) is a growing trend in the field of anesthesiology. However, formal POCUS curriculums are still not widely implemented in residency programs. As the Accreditation Council for Graduate Medical Education and the American Board of Anesthesiology have both incorporated POCUS into their educational aims and expectations for graduates, we recognized the need for a formal POCUS curriculum for our residency program. We developed and implemented a comprehensive 3-week POCUS curriculum for our first-year anesthesiology residents (CA1s) in the latter half of their academic year.

METHODS: Twenty CA1s participated in this educational activity. The POCUS …

Exercise-Induced Myokines Downregulates The Ace2 Level In Bronchial Epithelial Cells: Implications For Sars-Cov-2 Prevention, Vaishali Bhardwaj, Mart Dela Cruz, Deepika Subramanyam, Rohit Kumar, Sandeep Markan, Beth Parker, Hemant K Roy

Faculty, Staff and Students Publications

BACKGROUND: The Covid-19 pandemic has emerged as the leading public health challenge of our time (20th century). While vaccinations have finally blunted the death rate, concern has remained about more virulent forms highlighting the need for alternative approaches. Epidemiological studies indicate that physical activity has been shown to decrease the risk of infection of some respiratory viruses. Part of the salutary effects of exercise is believed to be through the elaboration of cytokines by contracting skeletal muscles (termed myokines). The objective of this study was to investigate whether exercise-induced myokines would mitigate the SARS-CoV-2 infectivity of the bronchial epithelium through …

A Precision Medicine Agenda In Traumatic Brain Injury, Jovany Cruz Navarro, Lucido L Ponce Mejia, Claudia Robertson

Faculty, Staff and Students Publications

Traumatic brain injury remains a leading cause of death and disability across the globe. Substantial uncertainty in outcome prediction continues to be the rule notwithstanding the existing prediction models. Additionally, despite very promising preclinical data, randomized clinical trials (RCTs) of neuroprotective strategies in moderate and severe TBI have failed to demonstrate significant treatment effects. Better predictive models are needed, as the existing validated ones are more useful in prognosticating poor outcome and do not include biomarkers, genomics, proteonomics, metabolomics, etc. Invasive neuromonitoring long believed to be a "game changer" in the care of TBI patients have shown mixed results, and …

Management Of Perioperative Anticoagulation In A Patient With Antiphospholipid Antibody Syndrome Undergoing Cardiac Surgery: A Case Report, Sanjana A Malviya, Yi Deng, Sayyed O Gilani, Alec A Hendon, Melissa A Nikolaidis, Micah S Moseley

Faculty, Staff and Students Publications

Patients with Antiphospholipid syndrome (APLS) are at high risk for both bleeding and thrombotic complications during cardiac surgery involving cardiopulmonary bypass (CPB). In this case we present a patient with APLS and Immune Thrombocytopenic Purpura who successfully underwent aortic valve replacement (AVR) with CPB despite recent craniotomy for subdural hematoma evacuation. Anticoagulation for CPB was monitored by targeting an Activated Clotting Time (ACT) that was 2× the upper limit of normal. A multidisciplinary approach was essential in ensuring a safe and successful operation.
