3-In-1 Hybrid Learning Environment, Holly Hapke, Anita Lee-Post, Tereza Dean Dec 2020

3-In-1 Hybrid Learning Environment, Holly Hapke, Anita Lee-Post, Tereza Dean

Marketing & Supply Chain Faculty Publications

We propose a learning innovation called 3-in-1 Hybrid environment as a solution for educational institutions to meet the challenge of balancing campus reopening against public health risks amid the COVID-19 pandemic. Our proposed innovation provides students options to attend class synchronously (either face-to-face or remote) or asynchronously (online) in an interactive learning environment that promotes emotional, behavioral, and cognitive engagement. We designed and implemented a large Marketing Management class with over 800 students as a 3-in-1 course. We examined its effectiveness in an empirical study and found that (1) students have a positive attitude toward 3-in-1 Hybrid learning; (2) they …

Near Conformal Perturbation Theory In Syk Type Models, Sumit R. Das, Animik Ghosh, Antal Jevicki, Kenta Suzuki Dec 2020

Near Conformal Perturbation Theory In Syk Type Models, Sumit R. Das, Animik Ghosh, Antal Jevicki, Kenta Suzuki

Physics and Astronomy Faculty Publications

We present a systematic procedure to extract the dynamics of the low energy soft mode in SYK type models with a single energy scale J and emergent reparametrization symmetry in the IR. This is given in the framework of the perturbative scheme of arXiv:1608.07567 based on a specific (off-shell) breaking of conformal invariance in the UV, adjusted to yield the exact large-N saddle point. While this breaking term formally vanishes on-shell, it has a non-trivial effect on correlation functions and the effective action. In particular, it leads to the Schwarzian action with a specific coupling to bi-local matter. The …

Biosystems and Agricultural Engineering Faculty Publications

This study developed a mathematical model following the fundamental principles of mass transfer for the simulation of the oil and moisture content change during the Deep-Fat Frying of plantain (ipekere) chip. The explicit Finite Difference Technique (FDT) was used to conduct a numerical solution to the consequential governing equation (partial differential equation) that was used to describe the mass transfer rate during the process. Computer codes that were computed in MATLAB were used for the implementation of FDT at diverse frying conditions. Samples of the plantain were cut into portions of 2 mm thickness, and these sliced portions …


Prospective Evaluation Of Association Between Negative Emotions And Heart Failure Symptom Severity, Kyoung Suk Lee, Terry A. Lennie, Debra K. Moser Dec 2020

Prospective Evaluation Of Association Between Negative Emotions And Heart Failure Symptom Severity, Kyoung Suk Lee, Terry A. Lennie, Debra K. Moser

Nursing Faculty Publications

Background: Prior studies of symptoms in heart failure (HF) were largely cross-sectional and symptoms were measured using retrospective recall. Because negative emotions influence information processing, retrospective symptom reports by patients with depressive symptoms and anxiety may be biased. The purpose of this study was to determine whether there are differences in patterns of symptom changes, measured prospectively, over 15 days by levels of depressive symptoms and anxiety.

Methods: HF patients (N=52) rated daily symptom severity for shortness of breath (SOB), fatigue, sleep disturbance, and edema over 15 days on a 10-point visual analogue scale. Patients were grouped into higher vs …

Dietetics and Human Nutrition Faculty Publications

Introduction

Obesity disproportionately affects rural communities, and Appalachia has some of the highest obesity rates in the nation. Successful policy, systems, and environmental (PSE) interventions to reduce obesity must reflect the circumstances of the population. We used a health equity lens to identify barriers and facilitators for healthy food access in Martin County, Kentucky, to design interventions responsive to social, cultural, and historical contexts.

Methods

We conducted 5 focus groups in Martin County, Kentucky, in fall 2019 to obtain perspectives on the local food system and gauge acceptability of PSE interventions. We used grounded theory to identify perceived barriers and …

Bilirubin Nanoparticles Reduce Diet-Induced Hepatic Steatosis, Improve Fat Utilization, And Increase Plasma Β-Hydroxybutyrate, Terry D. Hinds Jr., Justin F. Creeden, Darren M. Gordon, Donald F. Stec, Matthew C. Donald, David E. Stec

Pharmacology and Nutritional Sciences Faculty Publications

The inverse relationship of plasma bilirubin levels with liver fat accumulation has prompted the possibility of bilirubin as a therapeutic for non-alcoholic fatty liver disease. Here, we used diet-induced obese mice with non-alcoholic fatty liver disease treated with pegylated bilirubin (bilirubin nanoparticles) or vehicle control to determine the impact on hepatic lipid accumulation. The bilirubin nanoparticles significantly reduced hepatic fat, triglyceride accumulation, de novo lipogenesis, and serum levels of liver dysfunction marker aspartate transaminase and ApoB100 containing very-low-density lipoprotein. The bilirubin nanoparticles improved liver function and activated the hepatic β-oxidation pathway by increasing PPARα and acyl-coenzyme A oxidase 1. …


Experimental Manipulations To Test Theory-Driven Mechanisms Of Cognitive Behavior Therapy, Matthew W. Southward, Shannon Sauer-Zavala Dec 2020

Experimental Manipulations To Test Theory-Driven Mechanisms Of Cognitive Behavior Therapy, Matthew W. Southward, Shannon Sauer-Zavala

Psychology Faculty Publications

Despite decades of randomized-controlled trials demonstrating the efficacy of cognitive-behavior therapy (CBT), the mechanisms by which CBT achieves its effects remain unclear. Here, we describe how one adaptive intervention, the sequential multiple assignment randomized trial (SMART), can be used to randomize patients at multiple decision points in treatment to draw stronger causal claims about mechanisms unfolding in the course of CBT. We illustrate this design using preliminary data and case examples from an ongoing SMART in which we are testing the role of aversive reactions to negative emotions as a hypothesized mechanism of change in the Unified Protocol. Finally, we …

Cd47 Differentially Regulates White And Brown Fat Function, Heather Norman-Burgdolf, Dong Li, Patrick G. Sullivan, Shuxia Wang Dec 2020

Cd47 Differentially Regulates White And Brown Fat Function, Heather Norman-Burgdolf, Dong Li, Patrick G. Sullivan, Shuxia Wang

Pharmacology and Nutritional Sciences Faculty Publications

Mechanisms that enhance energy expenditure are attractive therapeutic targets for obesity. Previously we have demonstrated that mice lacking cd47 are leaner, exhibit increased energy expenditure, and are protected against diet-induced obesity. In this study, we further defined the physiological role of cd47 deficiency in regulating mitochondrial function and energy expenditure in both white and brown adipose tissue. We observed that cd47 deficient mice (under normal chow diet) had comparable amount of white fat mass but reduced white adipocyte size as compared to wild-type mice. Subsequent ex vivo and in vitro studies suggest enhanced lipolysis, and not impaired lipogenesis or energy …


Emerald Ash Borer Specific Gene Silencing Has No Effect On Non-Target Organisms, Flavia Pampolini, Lynne K. Rieske Dec 2020

Emerald Ash Borer Specific Gene Silencing Has No Effect On Non-Target Organisms, Flavia Pampolini, Lynne K. Rieske

Entomology Faculty Publications

The sequence complementarity of the RNA interference (RNAi) pathway allows for targeted suppression of genes essential for insect survival, and enables development of pest management strategies specific to a given species while reducing the likelihood of adversely impacting non-target organisms (NTOs). The feasibility of manipulating the RNAi pathway to cause mortality in the highly invasive emerald ash borer (EAB) has been demonstrated. Here the spectrum of activity of three double stranded RNAs (dsRNAs) targeting the genes hsp, shi, and sn-rnp in EAB was evaluated in model insects representing five functional guilds including herbivore, predator, detritivore, pollinator, parasitoid; …

Internal Medicine Faculty Publications

Exposure to blast overpressure waves is implicated as the major cause of ocular injuries and resultant visual dysfunction in veterans involved in recent combat operations. No effective therapeutic strategies have been developed so far for blast-induced ocular dysfunction. Lysophosphatidic acid (LPA) is a bioactive phospholipid generated by activated platelets, astrocytes, choroidal plexus cells, and microglia and is reported to play major roles in stimulating inflammatory processes. The levels of LPA in the cerebrospinal fluid have been reported to increase acutely in patients with traumatic brain injury (TBI) as well as in a controlled cortical impact (CCI) TBI model in mice. …


Natural Product Heme Oxygenase Inducers As Treatment For Nonalcoholic Fatty Liver Disease, David E. Stec, Terry D. Hinds Jr. Dec 2020

Natural Product Heme Oxygenase Inducers As Treatment For Nonalcoholic Fatty Liver Disease, David E. Stec, Terry D. Hinds Jr.

Pharmacology and Nutritional Sciences Faculty Publications

Heme oxygenase (HO) is a critical component of the defense mechanism to a wide variety of cellular stressors. HO induction affords cellular protection through the breakdown of toxic heme into metabolites, helping preserve cellular integrity. Nonalcoholic fatty liver disease (NAFLD) is a pathological condition by which the liver accumulates fat. The incidence of NAFLD has reached all-time high levels driven primarily by the obesity epidemic. NALFD can progress to nonalcoholic steatohepatitis (NASH), advancing further to liver cirrhosis or cancer. NAFLD is also a contributing factor to cardiovascular and metabolic diseases. There are currently no drugs to specifically treat NAFLD, with …

The Impact Of Standards-Based Learning: Tracking High School Students’ Transition To The University, Thomas R. Guskey, Matt Townsley, Thomas M. Buckmiller

Educational, School, and Counseling Psychology Faculty Publications

This study sought to determine if the implementation of standards-based learning in high schools affects students’ transition to learning in university courses. Surveys and interviews with 13 students who had graduated from high schools implementing standards-based learning and who had completed their first academic semester at a midsize, private, Midwest university revealed no detrimental effects. The most frequently mentioned transition difficulties related to social issues and time management. Implications for implementing high school grading reforms are discussed.

Entomology Faculty Publications

Tomato spotted wilt orthotospovirus (TSWV) causes serious crop losses worldwide and is transmitted by Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae). NSs protein is the silencing suppressor of TSWV and plays an important role in virus infection, cycling, and transmission process. In this research, we investigated the influences of NSs protein on the interaction of TSWV, plants, and F. occidentalis with the transgenic Arabidopsis thaliana. Compared with the wild-type Col-0 plant, F. occidentalis showed an increased number and induced feeding behavior on transgenic Arabidopsis thaliana expressing exogenous NSs. Further analysis showed that NSs reduced the expression of terpenoids synthesis-related genes and …


Cellular Proliferation Of Equine Bone Marrow- And Adipose Tissue-Derived Mesenchymal Stem Cells Decline With Increasing Donor Age, Jasmin Bagge, James N. Macleod, Lise C. Berg Dec 2020

Cellular Proliferation Of Equine Bone Marrow- And Adipose Tissue-Derived Mesenchymal Stem Cells Decline With Increasing Donor Age, Jasmin Bagge, James N. Macleod, Lise C. Berg

Maxwell H. Gluck Equine Research Center Faculty Publications

Background: Bone marrow (BM)- and adipose tissue (AT)-derived mesenchymal stem cells (MSCs) are used increasingly for autologous cell therapy in equine practice to treat musculoskeletal and other injuries. Current recommendations often call for 10–100 million MSCs per treatment, necessitating the expansion of primary cells in culture prior to therapeutic use. Of concern, human and rodent studies have shown a decline of both MSC recovery from sampled tissue and in vitro proliferative capacity with increasing donor age. This may be problematic for applications of autologous cell-based therapies in the important equine demographic of older patients.

Objectives: To investigate the effect of …
