Adding Gene Transcripts Into Genomic Prediction Improves Accuracy And Reveals Sampling Time Dependence., Bruno C Perez, Marco C A M Bink, Karen L. Svenson, Gary Churchill, Mario P L Calus

Faculty Research 2022

Recent developments allowed generating multiple high-quality 'omics' data that could increase the predictive performance of genomic prediction for phenotypes and genetic merit in animals and plants. Here, we have assessed the performance of parametric and nonparametric models that leverage transcriptomics in genomic prediction for 13 complex traits recorded in 478 animals from an outbred mouse population. Parametric models were implemented using the best linear unbiased prediction, while nonparametric models were implemented using the gradient boosting machine algorithm. We also propose a new model named GTCBLUP that aims to remove between-omics-layer covariance from predictors, whereas its counterpart GTBLUP does not do …

Visual Ecology: Sensing The Social World, Elliott P. Steele

Dartmouth College Ph.D Dissertations

Social animals, and even solitary animals, must at different points in their life actively search for and locate conspecifics within their environment, using one or multiple senses. One sense in particular, vision, can provide some of the most spatially detailed and temporally rapid information about the environment. Yet, the surrounding environment can also severely challenge animals’ abilities to find fellow conspecifics. Furthermore, once an animal successfully locates conspecifics, it must then make key decisions about when and where to enter group formations, decisions which may strongly impact their access to socially-acquired resources. Even after an animal has positioned itself within …

Blockade Of Fgf2/Fgfr2 Partially Overcomes Bone Marrow Mesenchymal Stromal Cells Mediated Progression Of T-Cell Acute Lymphoblastic Leukaemia, Chen Tian, Yueyang Li, Lina Wang, Junqi Si, Yaxin Zheng, Junnan Kang, Yafei Wang, M James You, Guoguang Zheng

Faculty, Staff and Student Publications

The development of acute lymphoblastic leuakemia (ALL) is partly attributed to the effects of bone marrow (BM) microenvironment, especially mesenchymal stromal cells (MSCs), which interact bilaterally with leukaemia cells, leading to ALL progression. In order to find MSCs-based microenvironment targeted therapeutic strategies, Notch1-induced T-cell ALL (T-ALL) mice models were used and dynamic alterations of BM-MSCs with increased cell viability during T-ALL development was observed. In T-ALL mice derived stroma-based condition, leukaemia cells showed significantly elevated growth capacity indicating that MSCs participated in leukaemic niche formation. RNA sequence results revealed that T-ALL derived MSCs secreted fibroblast growth factor 2 (FGF2), which …

Uses And Benefits Of Algae As A Nutritional Supplement For Honey Bees, Benjamin J. Nichols, Vincent A. Ricigliano

Department of Entomology: Faculty Publications

Honey bees are essential agricultural pollinators that are threatened by various interacting stressors, posing risks to beekeeping industries and human food security. Malnutrition is a major factor underlying managed bee colony losses that can be countered by feeding artificial diets, which aim to deliver essential macro- and micronutrients. Current bee nutritional supplements show room for improvement and require resources that compete with human food production. Algae and microalgae in particular have been gaining traction in the literature as alternative feed sources and nutritional supplements for livestock, including honey bees. Herein, we review the current literature and categorize the effects of …

Do Pharmaceuticals In The Environment Pose A Risk To Wildlife?, Thomas G. Bean, Elizabeth A. Chadwick, Marta Herrero‐Villar, Rafael Mateo, Vinny Naidoo, Barnett A. Rattner

United States Geological Survey: Staff Publications

The vast majority of knowledge related to the question “To what extent do pharmaceuticals in the environment pose a risk to wildlife?” stems from the Asian vulture crisis (>99% decline of some species of Old World vultures on the Indian subcontinent related to the veterinary use of the nonsteroidal anti‐inflammatory drug [NSAID] diclofenac). The hazard of diclofenac and other NSAIDs (carprofen, flunixin, ketoprofen, nimesulide, phenylbutazone) to vultures and other avian species has since been demonstrated; indeed, only meloxicam and tolfenamic acid have been found to be vulture‐safe. Since diclofenac was approved for veterinary use in Spain and Italy in …

Supplements To Reduce Methane Production In Ruminant Animals, Abdulaziz Almaghrabi

Research Papers

Changes in the climate continue to be one of the world's most pressing issues. The accumulation methane (CH4) in the atmosphere is a major driver of these changes. Ruminant animals have been identified as substantial contributors to CH4 emissions. This assertion is supported by the fact that ruminant animals have a unique digestive tract that allows them to digest complex polysaccharides by the action of microbes in their rumen. During the microbial digestion (fermentation) of dietary polysaccharides, CH4 is produced as a byproduct of the process. Therefore, this paper aims to analyze this issue, highlight how ruminants contribute to this …

Mitochondrial Protective Effects Caused By The Administration Of Mefenamic Acid In Sepsis, Diogo Dominguini, Monique Michels, Leticia B Wessler, Emilio L Streck, Tatiana Barichello, Felipe Dal-Pizzol

Faculty, Staff and Student Publications

The pathophysiology of sepsis may involve the activation of the NOD-type receptor containing the pyrin-3 domain (NLPR-3), mitochondrial and oxidative damages. One of the primary essential oxidation products is 8-oxoguanine (8-oxoG), and its accumulation in mitochondrial DNA (mtDNA) induces cell dysfunction and death, leading to the hypothesis that mtDNA integrity is crucial for maintaining neuronal function during sepsis. In sepsis, the modulation of NLRP-3 activation is critical, and mefenamic acid (MFA) is a potent drug that can reduce inflammasome activity, attenuating the acute cerebral inflammatory process. Thus, this study aimed to evaluate the administration of MFA and its implications for …

Effects Of Physical Activity On The Cognitive Performance Of Older Adults With Cognitive Impairment: A Critically Appraised Topic, Amaiah N. Young

Honors College Theses

The aging population is the fastest growing population currently. Older adults are most susceptible to cognitive impairment, because of the natural cognitive decline with age. Physical activity changes the body physically by increasing strength and endurance of muscles, and aids quality of life by decreasing the negative impact of cognitive impairment. This study investigated the influence of physical activity on cognitive performance of cognitively impaired older adults. This study found that physical activity had a beneficial effect on cognition when physical activity plans were done for at least 6 months and of moderate to high intensity. While, all areas of …

Reprogramming Of Pancreatic Adenocarcinoma Immunosurveillance By A Microbial Probiotic Siderophore, Mehdi Chaib, Bilal B. Hafeez, Hassan Mandil, Deidre Daria, Ajeeth K. Pingili, Sonam Kumari, Mohammed Sikander, Vivek K. Kashyap, Emmanuel Anning, Manish Tripathi, Sheema Khan, Stephen Behrman, Murali M. Yallapu, Meena Jaggi, Subhash C. Chauhan

School of Medicine Publications

There is increasing evidence suggesting the role of microbiome alterations in relation to pancreatic adenocarcinoma and tumor immune functionality. However, molecular mechanisms of the interplay between microbiome signatures and/or their metabolites in pancreatic tumor immunosurveillance are not well understood. We have identified that a probiotic strain (Lactobacillus casei) derived siderophore (ferrichrome) efficiently reprograms tumor-associated macrophages (TAMs) and increases CD8 + T cell infiltration into tumors that paralleled a marked reduction in tumor burden in a syngeneic mouse model of pancreatic cancer. Interestingly, this altered immune response improved anti-PD-L1 therapy that suggests promise of a novel combination (ferrichrome and …

Beyond Health And Animal Rights: A Study In Black Veganism, Wendy J. Rib

USF Tampa Graduate Theses and Dissertations

Veganism, or the avoidance of animal products, has been recognized by nutritionists and food scientists as a lifestyle choice associated with good health and lower prevalence of diabetes, obesity, hypertension, and heart disease. However, the choice to eschew all animal products is frequently more than just a diet. Many people practice veganism as part of a larger reformative social movement, seeking permanent change in food structures, advancing policies in animal welfare and transforming their everyday lives in the quest for cultural acceptance. Although the number of people who identify as vegans appears to be growing, it is often assumed that …

Paraquat-Resistant Italian Ryegrass (Lolium Multiflorum) Confirmed In Louisiana, Alphonse B. Coco Iii

LSU Master's Theses

Paraquat is the only herbicide labeled for postemergence control of Italian ryegrass in sugarcane. In 2017, sugarcane farmers in Louisiana reported Italian ryegrass control failures with paraquat applications. Seeds were collected from sugarcane fields in White Castle, St. Gabriel, and Bunkie, Louisiana where control was not achieved (reduced susceptibility). Additionally, Italian ryegrass seeds were collected from a sugarcane field in Welcome, LA with a history of paraquat use and with no reported control issues (susceptible population). A dose-response study was conducted at the Louisiana State University Agricultural Center’s Sugar Research Station in February 2021 and was repeated in November 2021. …

Improved Livelihoods From Grasslands; The Case Of Napier Grass In Smallholder Dairy Farms In Kenya, David Miano Mwangi, D. Romney, S. Staal, I. Baltenweck, S. Mwendia

IGC Proceedings (1977-2023)

In Kenya, smallholder farmers produce about 80% of the marketed milk. The farming systems vary from mixed farms with up to 10 ha of land and < 10 dairy cows (Gitau et al., 1994; Anon., 1985), to intensive smallholder dairy producers in the high human population central Kenya region with 0.9 to 2 ha of land and 3-4 dairy cows (Staal et al., 2001a). Milk production depends heavily on the cultivation of forages, with Pennisetum purpureum (Napier grass) by far the most important. An estimated 350,000 of the 600,000 smallholder farms in Kenya grow and utilize P. purpureum on their farms.

There are …

Role Of Information And Information Providers In Technology Transfer, D. Undersander

IGC Proceedings (1977-2023)

Technology transfer is an essential component of economic change in society. Developers of new technology often fail to realize that there is a science to technology transfer. This lack of appreciation for the skills involved in information dissemination and in activities necessary to affect a change of action in an audience often severely limits the rate and amount of technology transfer that occurs. Significant differences exist between doing a news release or writing a publication and causing audience acceptance of a new technology. The old standards of expecting adoption of a new technology simply because it “will profit farmers” or …

The Contribution Of Participatory Research: On-Farm Research, P. F. Fennessy, N. J. Daniels, S. A. Chadwick, P. A. Speck

IGC Proceedings (1977-2023)

Participatory research in agriculture may range from research and technology development (R&D), carried out on a research station with some involvement of farmers, through to genuine participatory research involving researchers and farmers working together. The latter involves the end-user in actually carrying out aspects of the research and/or in the development and evaluation of technology that is appropriate to commercial enterprises. Researchers often question the validity of the ‘findings of on-farm participatory research’ as they are more comfortable with the ‘controlled’ environment of the research station. However if research is to be applied appropriately on farms, it must go through …

Participatory Research For Smallholder Livestock Systems: Applying Common Sense To Complex Problems, P. M. Horne, Werner Stür

IGC Proceedings (1977-2023)

Key Points:

1. Participatory approaches to research (PAR) bring researchers closer to farmers, the intended users of research outputs.

2. Active, functional participation of farmers in the evaluation and development of new technologies requires researchers to make an important commitment: respecting the knowledge, skills and opinions of farmers while maintaining confidence in their own scientific knowledge.

3. Farmer experimentation is not usually suitable to provide quantitative biophysical data (this can be achieved more effectively in researcher controlled experiments), but to provide qualitative information and improve understanding. This type of information can be collected systematically to enable rigorous analysis.

4. While …

Not All Competitions Are The Same: Digital Game-Based Learning Environments That Incorporate Competition Facilitates Students' Learning Motivation, Yong Zeng, John E. Mceneaney

Journal of Research Initiatives

This text presents an argument that competition, as a pedagogical design element, facilitates students’ learning motivation in digital game-based learning environments (DGBLEs). Since competition has long been regarded as an adverse pedagogical element for fostering students’ learning motivation, a considerable proportion of educators and researchers in the U.S. have a variety of concerns about implementing competition in educational practices. However, the function of competition in DGBLEs could be fundamentally different. By reviewing major concerns about competition, this text refutes two major concerns about competition and claims that DGBLEs that incorporate competition facilitate students' learning motivation
