Sugar Recovery Rates In Louisiana, Florida, And Australia (1901–2018): Sugarcane Varietal Development And Cultural Practices, P. Lynn Kennedy, Andrew Schmitz, Fangyi Zhang

Faculty Publications

Australia, Florida, and Louisiana are dominant sugar producers. We use piecewise regression to compare the growth in sugar recovery rates. To discuss sugarcane (Saccharum officinarum L.) varietal development and cultural practices, we consider two scenarios: the entire period 1901 to 2018 and two subperiods using country-specific breakpoints. The overall annual increase in the sugar recovery rate for all three regions ranged between 0.0180% for Australia and 0.0525% for Florida. In the first subperiod, Florida (0.2380%, 1928–1941) and Australia (0.1233%, 1901–1927) have the greatest annual gains, but in the second subperiod, Louisiana experiences the greatest annual gains (0.0813%, 1969–2018), followed by …

Kentucky Soybean Farmers' Supportiveness Of Two Integrated Pest And Pollinator Management Tactics, Hannah J. Penn, Jerrod Penn, Michael Cunningham-Minnick, Wuyang Hu Jan 2021

Kentucky Soybean Farmers' Supportiveness Of Two Integrated Pest And Pollinator Management Tactics, Hannah J. Penn, Jerrod Penn, Michael Cunningham-Minnick, Wuyang Hu

Faculty Publications

Beneficial insect conservation in agriculture is often studied in the context of integrated pest management (IPM). For instance, vegetative field edges provide habitat and changing the timing of insecticidal sprays decreases risk for pollinators and natural enemies of insect pests. However, the attitudes and confidence of U.S. growers towards IPM implementation in traditional row crops remain understudied. We developed an online survey using a convenience sample and surveyed Kentucky soybean growers to understand their current pest and general management practices, beliefs about sources of insect pests/weeds, and attitudes towards pollinators. We also asked about their willingness to implement two management …

Studying Morphological, Physiological, And Molecular Regulation Of Stomatal Conductance And Its Relationship To Water Use Efficiency In Alfalfa, Surbhi Gupta

Electronic Theses and Dissertations

Alfalfa (Medicago sativa), being a leguminous, highly fibrous, and proteinaceous plant has always been one of the top choices for the forage production but has high cost of irrigation in many dry and warm areas such as California and Arizona. Thus, a reduction of irrigation by using the higher water use efficiency (WUE) varieties can help the growers in reducing the cost and is critical for sustainable agriculture production. WUE is closely related to water loss through transpiring stomata. A study in our lab reported that Riverside (RS) an alfalfa genotype that has naturized in the national grassland in South …

Novel Acetylcholine Chloride Based Water Immiscible Deep Eutectic Solvent: Formulation, Characterization And Application In Drug Solubilization, Shiksha Subedi

Electronic Theses and Dissertations

Deep eutectic solvents (DESs) are the emerging class of new and inexpensive solvents composed of two or three safe components capable of self-association through hydrogen bond interaction. The depression in the melting point characterizes DESs compared to those of the individual components. These solvents have properties like the traditionally used ionic liquids (ILs), but they can offset the significant drawbacks of ILs, such as biodegradability, toxicity, and complex synthesis. Due to these remarkable advantages, the research in DESs is increasing exponentially. However, current deep eutectic solvents still have limitations to apply to the real chemical industries due to hydrophilicity and …

Viral And Immune Studies On Bovine Viral Diarrhea Virus (Bvdv) In Bovine Species, Karim Abdelsalam Jan 2021

Viral And Immune Studies On Bovine Viral Diarrhea Virus (Bvdv) In Bovine Species, Karim Abdelsalam

Electronic Theses and Dissertations

BVDV is a major pathogen of ruminants that causes immune dysfunction and lead to secondary bacterial infection. The underlying mechanism of this dysfunction is not well understood. Based on previous results, we believe that macrophages play a central role in BVDV-associated immune dysfunction. Previously, we have shown that the infected monocyte-derived macrophage (MDM) supernatant of the high virulent strains of BVDV significantly induced lymphocyte apoptosis. In the current study, we performed experiments to identify the apoptotic factors in the infected MDM supernatants in vitro. Also, we have extended our investigation to include testing the impact of infected macrophages on neutrophil …

In The Service Of God And Humanity: Conscience, Reason, And The Mind Of Martin R. Delany, Philip Yaure

Civil War Book Review

Adeleke shows that Delaney was alternatively a separatist, integrationist, militarist, and accommodationist before returning to his previous belief in emigration. Despite his changing methods, a puzzling belief in the power of moral suasion animated all of Delaney’s emancipationist efforts. This puzzlement is indicative of “the success of Adeleke’s project.”

Caregiver Treatment Consumption In An Experimental Treatment Marketplace, Delaney J. Darragh Jan 2021

Caregiver Treatment Consumption In An Experimental Treatment Marketplace, Delaney J. Darragh

Faculty Publications

Behavioral economics is an approach to understanding consumer behavior by integrating behavioral science with economic principles. Behavioral economics incorporates traditional economic principles with operant learning approaches. There is limited research examining how individuals consume psychological and behavioral treatments. This is especially the case for treatments designed for children. The current study used data from a previously collected sample to explore gender differences in an experimental treatment marketplace (ETM). Experimental treatment marketplaces are generally used to evaluate choices between goods and services (e.g., types of behavior interventions). An ETM was developed to evaluate treatment consumption when levels of evidence differed between …

Siah2 Is Expressed In Adipocyte Precursor Cells And Interacts With Ebf1 And Zfp521 To Promote Adipogenesis, Thanh N. Dang, Jessica L. Taylor, Gail Kilroy, Yongmei Yu, David H. Burk, Z. Elizabeth Floyd

Division of Basic Science Faculty Publications

Objective: Expression of zinc finger protein 423 (ZFP423), a key proadipogenic transcription factor in adipocyte precursor cells, is regulated by interaction of the proadipogenic early B-cell factor 1 (EBF1) and antiadipogenic ZFP521. The ubiquitin ligase seven-in-absentia homolog 2 (SIAH2) targets ZFP521 for degradation. This study asked whether SIAH2 is expressed in adipocyte precursor cells and whether SIAH2 interacts with ZFP521 and EBF1 to regulate ZFP521 protein levels during adipogenesis. Methods: SIAH2 expression in precursor cells was assessed in primary cells and tissues from wild-type and SIAH2 null mice fed a control or high-fat diet. Primary cells, 3T3-L1 preadipocytes, and HEK293T …

Caloric restriction (CR) is a strategy that attenuates aging in multiple nonhuman species. The Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy (CALERIE) trials are part of a research program aiming to test the effects of CR on aging and longevity biomarkers in humans. Building on CALERIE phase 1, CALERIE phase 2 (CALERIE 2) was the largest study to date to assess sustained CR in healthy humans without obesity. In a 24-month randomized controlled trial comprising 218 participants at baseline, CALERIE 2 showed that moderate CR, 11.9% on average, induced improvements in aging-related biomarkers without adversely affecting psychological …

Sympathetic Innervation Of White Adipose Tissue: To Beige Or Not To Beige?, Heike Münzberg, Elizabeth Floyd, Ji Suk Chang

Division of Basic Science Faculty Publications

Obesity research progresses in understanding neuronal circuits and adipocyte biology to regulate metabolism. However, the interface of neuro-adipocyte interaction is less studied. We summarize the current knowledge of adipose tissue innervation and interaction with adipocytes and emphasize adipocyte transitions from white to brown adipocytes and vice versa. We further highlight emerging concepts for the differential neuronal regulation of brown/beige versus white adipocyte and the interdependence of both for metabolic regulation.

Division of Basic Science Faculty Publications

Glucocorticoids are clinically essential drugs used routinely to control inflammation. However, a host of metabolic side effects manifests upon usage beyond a few days. In the present study, we tested the hypothesis that seven-in-absentia mammalian homolog-2 (SIAH2), a ubiquitin ligase that regulates adipogenesis, is important for controlling adipocyte size, inflammation, and the ability of adipose tissue to expand in response to a glucocorticoid challenge. Using mice with global deletion of SIAH2 exposed or not to corticosterone, we found that adipocytes are larger in response to glucocorticoids in the absence of SIAH2. In addition, SIAH2 regulates glucocorticoid receptor (GR) transcriptional activity …

The inflammatory response is an obstacle to success in both allogeneic and autologous islet transplantation. In autologous islet transplantation (AIT), however, the recipient is also the donor, permitting pretreatment of donor/recipient for a controlled duration prior to transplantation. We sought to exploit this feature of (AIT) by pretreating donor/recipients with chronic pancreatitis undergoing total pancreatectomy and autologous islet transplantation (TPAIT) to test the hypothesis that peri-transplant treatment with the FDA-approved anti-inflammatory hydroxychloroquine (HCQ) improves graft function. In this randomized placebo-controlled pilot clinical study, patients (n = 6) were treated with oral HCQ for 30 days prior to and 90 days …

Declining estrogen levels before, during, and after menopause can affect memory and risk for Alzheimer's disease. Undesirable side effects of hormone variations emphasize a role for hormone therapy (HT) where possible benefits include a delay in the onset of dementia—yet findings are inconsistent. Effects of HT may be mediated by estrogen receptors found throughout the brain. Effects may also depend on lifestyle factors, timing of use, and genetic risk. We studied the impact of self-reported HT use on brain volume in 562 elderly women (71–94 years) with mixed cognitive status while adjusting for aforementioned factors. Covariate-adjusted voxelwise linear regression analyses …

This paper traces the genesis and lineage of solopreneur digital ecosystems. These ecosystems, fostered by a digital environment that is infrastructural, combinatorial and servitized, are enabling the rise to prominence of the solopreneur. We theorize solopreneur digital ecosystems as the latest incarnation of systems beyond firm control, with digital platforms and digital marketplaces as their principal enablers. In an effort to compare them from the perspective of the solopreneur, we categorize solopreneur digital ecosystems on three dimensions: algorithmic control, commoditization, and lock-in. Our work contributes a framework that solopreneurs can use to identify ecosystems in which they can optimally invest …
